Selling Digital Music without Copy-protection Makes Sense
A. It was uncharacteristically low-key for the industry’s greatest showman.
But the essay published this week by Steve Jobs, the boss of Apple, on his
firm’s website under the unassuming title “Thoughts on Music” has nonetheless
provoked a vigorous debate about the future of digital music, which Apple
dominates with its iPod music-player and iTunes music-store. At issue is
“digital rights management” (DRM)—the technology guarding downloaded music
against theft. Since there is no common standard for DRM, it also has the
side-effect that songs purchased for one type of music-player may not work on
another. Apple’s DRM system, called FairPlay, is the most widespread. So it came
as a surprise when Mr. Jobs called for DRM for digital music to be
abolished.
B. This is a change of tack for Apple. It has come under fire from European
regulators who claim that its refusal to license FairPlay to other firms has
“locked in” customers. Since music from the iTunes store cannot be played on
non-iPod music-players (at least not without a lot of fiddling), any iTunes
buyer will be deterred from switching to a device made by a rival firm, such as
Sony or Microsoft. When French lawmakers drafted a bill last year compelling
Apple to open up FairPlay to rivals, the company warned of “state-sponsored
piracy”. Only DRM, it implied, could keep the pirates at bay.
C. This week Mr. Jobs gave another explanation for his former defence of DRM:
the record companies made him do it. They would make their music available to
the iTunes store only if Apple agreed to protect it using DRM. They can still
withdraw their catalogues if the DRM system is compromised. Apple cannot license
FairPlay to others, says Mr Jobs, because it would depend on them to produce
security fixes promptly. All DRM does is restrict consumer choice and provide a
barrier to entry, says Mr Jobs; without it there would be far more stores and
players, and far more innovation. So, he suggests, why not do away with DRM and
sell music unprotected? “This is clearly the best alternative for consumers,” he
declares, “and Apple would embrace it in a heartbeat.”
D. Why the sudden change of heart? Mr Jobs seems chiefly concerned with
getting Europe’s regulators off his back. Rather than complaining to Apple about
its use of DRM, he suggests, “those unhappy with the current situation should
redirect their energies towards persuading the music companies to sell their
music DRM-free.” Two and a half of the four big record companies, he helpfully
points out, are European-owned. Mr Jobs also hopes to paint himself as a
consumer champion. Apple resents accusations that it has become the Microsoft of
digital music.
E. Apple can afford to embrace open competition in music players and online
stores. Consumers would gravitate to the best player and the best store, and at
the moment that still means Apple’s. Mr Jobs is evidently unfazed by rivals to
the iPod. Since only 3% of the music in a typical iTunes library is protected,
most of it can already be used on other players today, he notes. (And even the
protected tracks can be burned onto a CD and then re-ripped.) So Apple’s
dominance evidently depends far more on branding and ease of use than
DRM-related “lock in”.
F. The music giants are trying DRM-free downloads. Lots of smaller labels
already sell music that way. Having seen which way the wind is blowing, Mr Jobs
now wants to be seen not as DRM’s defender, but as a consumer champion who
helped in its downfall. Wouldn’t it lead to a surge in piracy? No, because most
music is still sold unprotected on CDs, people wishing to steal music already
can do so. Indeed, scrapping DRM would probably increase online-music sales by
reducing confusion and incompatibility. With the leading online store, Apple
would benefit most. Mr Jobs’s argument, in short, is transparently self-serving.
It also happens to be right.

new weapon to fight cancer
1. British scientists are preparing to launch trials of a radical new way to
fight cancer, which kills tumours by infecting them with viruses like the common
cold.
2. If successful, virus therapy could eventually form a third pillar
alongside radiotherapy and chemotherapy in the standard arsenal against cancer,
while avoiding some of the debilitating side-effects.
3. Leonard Seymour, a professor of gene therapy at Oxford University, who has
been working on the virus therapy with colleagues in London and the US, will
lead the trials later this year. Cancer Research UK said yesterday that it was
excited by the potential of Prof Seymour’s pioneering techniques.
4. One of the country’s leading geneticists, Prof Seymour has been working
with viruses that kill cancer cells directly, while avoiding harm to healthy
tissue. "In principle, you’ve got something which could be many times more
effective than regular chemotherapy," he said.
5. Cancer-killing viruses exploit the fact that cancer cells suppress the
body’s local immune system. "If a cancer doesn’t do that, the immune system
wipes it out. If you can get a virus into a tumour, viruses find them a very
good place to be because there’s no immune system to stop them replicating. You
can regard it as the cancer’s Achilles’ heel."
6. Only a small amount of the virus needs to get to the cancer. "They
replicate, you get a million copies in each cell and the cell bursts and they
infect the tumour cells adjacent and repeat the process," said Prof Seymour.
7. Preliminary research on mice shows that the viruses work well on tumours
resistant to standard cancer drugs. "It’s an interesting possibility that they
may have an advantage in killing drug-resistant tumours, which could be quite
different to anything we’ve had before."
8. Researchers have known for some time that viruses can kill tumour cells
and some aspects of the work have already been published in scientific journals.
American scientists have previously injected viruses directly into tumours but
this technique will not work if the cancer is inaccessible or has spread
throughout the body.
9. Prof Seymour’s innovative solution is to mask the virus from the body’s
immune system, effectively allowing the viruses to do what chemotherapy drugs do
- spread through the blood and reach tumours wherever they are. The big hurdle
has always been to find a way to deliver viruses to tumours via the bloodstream
without the body’s immune system destroying them on the way.
10. "What we’ve done is make chemical modifications to the virus to put a
polymer coat around it - it’s a stealth virus when you inject it," he said.
11. After the stealth virus infects the tumour, it replicates, but the copies
do not have the chemical modifications. If they escape from the tumour, the
copies will be quickly recognised and mopped up by the body’s immune system.
12. The therapy would be especially useful for secondary cancers, called
metastases, which sometimes spread around the body after the first tumour
appears. "There’s an awful statistic of patients in the west ... with malignant
cancers; 75% of them go on to die from metastases," said Prof Seymour.
13. Two viruses are likely to be examined in the first clinical trials:
adenovirus, which normally causes a cold-like illness, and vaccinia, which
causes cowpox and is also used in the vaccine against smallpox. For safety
reasons, both will be disabled to make them less pathogenic in the trial, but
Prof Seymour said he eventually hopes to use natural viruses.
14. The first trials will use uncoated adenovirus and vaccinia and will be
delivered locally to liver tumours, in order to establish whether the treatment
is safe in humans and what dose of virus will be needed. Several more years of
trials will be needed, eventually also on the polymer-coated viruses, before the
therapy can be considered for use in the NHS. Though the approach will be
examined at first for cancers that do not respond to conventional treatments,
Prof Seymour hopes that one day it might be applied to all cancers.
Questions 1-6
Do the following statements agree with the information given in the reading
passage? For questions 1-6 write
TRUE if the statement agrees with the information
FALSE if the statement contradicts the information
NOT GIVEN if there is no information on this in the passage
1.Virus therapy, if successful, has an advantage in eliminating
side-effects.
2.Cancer Research UK is quite hopeful about Professor Seymour’s work on the
virus therapy.
3.Virus can kill cancer cells and stop them from growing again.
4.Cancer’s Achilles’ heel refers to the fact that virus may stay safely in a
tumor and replicate.
5.To infect the cancer cells, a good deal of viruses should be injected into
the tumor.
6.Researches on animals indicate that virus could be used as a new way to
treat drug-resistant tumors.

How a Frenchman is reviving McDonald’s in Europe
A. When Denis Hennequin took over as the European boss of McDonald’s in
January 2004, the world’s biggest restaurant chain was showing signs of recovery
in America and Australia, but sales in Europe were sluggish or declining. One
exception was France, where Mr Hennequin had done a sterling job as head of the
group’s French subsidiary to sell more Big Macs to his compatriots. His task was
to replicate this success in all 41 of the European countries where
anti-globalisers’ favourite enemy operates.
B. So far Mr Hennequin is doing well. Last year European sales increased by
5.8% and the number of customers by 3.4%, the best annual results in nearly 15
years. Europe accounted for 36% of the group’s profits and for 28% of its sales.
December was an especially good month as customers took to seasonal menu
offerings in France and Britain, and to a promotion in Germany based on the game
of Monopoly.
C. Mr Hennequin’s recipe for revival is to be more open about his company’s
operations, to be “locally relevant”, and to improve the experience of visiting
his 6,400 restaurants. McDonald’s is blamed for making people fat, exploiting
workers, treating animals cruelly, polluting the environment and simply for
being American. Mr Hennequin says he wants to engage in a dialogue with the
public to address these concerns.
D. He introduced “open door” visitor days in each country which became hugely
popular. In Poland alone some 50,000 visitors came to McDonald’s through the
visitors’ programme last year. The Nutrition Information Initiative, launched
last year, put detailed labels on McDonald’s packaging with data on calories,
protein, fat, carbohydrates and salt content. The details are also printed on
tray-liners.
E. Mr Hennequin also wants people to know that “McJobs”, the low-paid menial
jobs at McDonald’s restaurants, are much better than people think. But some of
his efforts have backfired: last year he sparked a controversy with the
introduction of a “McPassport” that allows McDonald’s employees to work anywhere
in the European Union. Politicians accused the firm of a ploy to make cheap
labour from eastern Europe more easily available to McDonald’s managers across
the continent.
F. To stay in touch with local needs and preferences, McDonald’s employs
local bosses as much as possible. A Russian is running McDonald’s in Russia,
though a Serb is in charge of Germany. The group buys mainly from local
suppliers. Four-fifths of its supplies in France come from local farmers, for
example. (Some of the French farmers who campaigned against the company in the
late 1990s subsequently discovered that it was, in fact, buying their produce.)
And it hires celebrities such as Heidi Klum, a German model, as local brand
ambassadors.
G. In his previous job Mr Hennequin established a “design studio” in France
to spruce up his company’s drab restaurants and adapt the interior to local
tastes. The studio is now masterminding improvements everywhere in Europe. He
also set up a “food studio”, where cooks devise new recipes in response to local
trends.
H. Given France’s reputation as the most anti-American country in Europe, it
seems odd that McDonald’s revival in Europe is being led by a Frenchman, using
ideas cooked up in the French market. But France is in fact the company’s most
profitable market after America. The market where McDonald’s is weakest in
Europe is not France, but Britain.
I. “Fixing Britain should be his priority,” says David Palmer, a restaurant
analyst at UBS. Almost two-thirds of the 1,214 McDonald’s restaurants in Britain
are company-owned, compared with 40% in Europe and 15% in America. The company
suffers from the volatility of sales at its own restaurants, but can rely on
steady income from franchisees. So it should sell as many underperforming
outlets as possible, says Mr Palmer.
J. M.Mark Wiltamuth, an analyst at Morgan Stanley, estimates that European
company-owned restaurants’ margins will increase slightly to 16.4% in 2007. This
is still less than in the late 1990s and below America’s 18-19% today. But it is
much better than before Mr Hennequin’s reign. He is already being tipped as the
first European candidate for the group’s top job in Illinois. Nobody would call
that a McJob.

1 There's a dimmer switch inside the sun that causes its brightness to rise
and fall on timescales of around 100,000 years - exactly the same period as
between ice ages on Earth. So says a physicist who has created a computer model
of our star's core.
2 Robert Ehrlich of George Mason University in Fairfax, Virginia, modelled
the effect of temperature fluctuations in the sun's interior. According to the
standard view, the temperature of the sun's core is held constant by the
opposing pressures of gravity and nuclear fusion. However, Ehrlich believed that
slight variations should be possible.
3 He took as his starting point the work of Attila Grandpierre of the Konkoly
Observatory of the Hungarian Academy of Sciences. In 2005, Grandpierre and a
collaborator, Gábor ágoston, calculated that magnetic fields in the sun's core
could produce small instabilities in the solar plasma. These instabilities would
induce localised oscillations in temperature.
4 Ehrlich's model shows that whilst most of these oscillations cancel each
other out, some reinforce one another and become long-lived temperature
variations. The favoured frequencies allow the sun's core temperature to
oscillate around its average temperature of 13.6 million kelvin in cycles
lasting either 100,000 or 41,000 years. Ehrlich says that random interactions
within the sun's magnetic field could flip the fluctuations from one cycle
length to the other.
5 These two timescales are instantly recognisable to anyone familiar with
Earth's ice ages: for the past million years, ice ages have occurred roughly
every 100,000 years. Before that, they occurred roughly every 41,000 years.
6 Most scientists believe that the ice ages are the result of subtle changes
in Earth's orbit, known as the Milankovitch cycles. One such cycle describes the
way Earth's orbit gradually changes shape from a circle to a slight ellipse and
back again roughly every 100,000 years. The theory says this alters the amount
of solar radiation that Earth receives, triggering the ice ages. However, a
persistent problem with this theory has been its inability to explain why the
ice ages changed frequency a million years ago.
7 "In Milankovitch, there is certainly no good idea why the frequency should
change from one to another," says Neil Edwards, a climatologist at the Open
University in Milton Keynes, UK. Nor is the transition problem the only one the
Milankovitch theory faces. Ehrlich and other critics claim that the temperature
variations caused by Milankovitch cycles are simply not big enough to drive ice
ages.
8 However, Edwards believes the small changes in solar heating produced by
Milankovitch cycles are then amplified by feedback mechanisms on Earth. For
example, if sea ice begins to form because of a slight cooling, carbon dioxide
that would otherwise have found its way into the atmosphere as part of the
carbon cycle is locked into the ice. That weakens the greenhouse effect and
Earth grows even colder.
9 According to Edwards, there is no lack of such mechanisms. "If you add
their effects together, there is more than enough feedback to make Milankovitch
work," he says. "The problem now is identifying which mechanisms are at work."
This is why scientists like Edwards are not yet ready to give up on the current
theory. "Milankovitch cycles give us ice ages roughly when we observe them to
happen. We can calculate where we are in the cycle and compare it with
observation," he says. "I can't see any way of testing [Ehrlich's] idea to see
where we are in the temperature oscillation."
10 Ehrlich concedes this. "If there is a way to test this theory on the sun,
I can't think of one that is practical," he says. That's because variation over
41,000 to 100,000 years is too gradual to be observed. However, there may be a
way to test it in other stars: red dwarfs. Their cores are much smaller than
that of the sun, and so Ehrlich believes that the oscillation periods could be
short enough to be observed. He has yet to calculate the precise period or the
extent of variation in brightness to be expected.
11 Nigel Weiss, a solar physicist at the University of Cambridge, is far from
convinced. He describes Ehrlich's claims as "utterly implausible". Ehrlich
counters that Weiss's opinion is based on the standard solar model, which fails
to take into account the magnetic instabilities that cause the temperature
fluctuations.

The Guardian
1. Consumers are to be presented with two rival new year advertising
campaigns as the Food Standards Agency goes public in its battle with the
industry over the labelling of unhealthy foods.
2. The Guardian has learned that the FSA will launch a series of 10-second
television adverts in January telling shoppers how to follow a red, amber and
green traffic light labelling system on the front of food packs, which is
designed to tackle Britain’s obesity epidemic.
3. The campaign is a direct response to a concerted attempt by leading food
manufacturers and retailers, including Kellogg’s and Tesco, to derail the
system. The industry fears that traffic lights would demonise entire categories
of foods and could seriously damage the market for those that are fatty, salty
or high in sugar.
4. The UK market for breakfast cereals is worth ￡1.27bn a year and the
manufacturers fear it will be severely dented if red light labels are put on
packaging drawing attention to the fact that the majority are high in salt
and/or sugar.
5. The industry is planning a major marketing campaign for a competing
labelling system which avoids colour-coding in favour of information about the
percentage of "guideline daily amounts" (GDAs) of fat, salt and sugar contained
in their products.
6. The battle for the nation’s diet comes as new rules on television
advertising come into force in January which will bar adverts for unhealthy
foods from commercial breaks during programmes aimed at children. Sources at the
TV regulators are braced for a legal challenge from the industry and have
described the lobbying efforts to block any new ad ban or colour-coded labelling
as "the most ferocious we’ve ever experienced".
7. Ofcom’s chief executive, Ed Richards, said: "We are prepared to face up to
any legal action from the industry, but we very much hope it will not be
necessary." The FSA said it was expecting an onslaught from the industry in
January. Senior FSA officials said the manufacturers’ efforts to undermine its
proposals on labelling could threaten the agency’s credibility.
8. Terrence Collis, FSA director of communications, dismissed claims that the
proposals were not based on science. "We have some of the most respected
scientists in Europe, both within the FSA and in our independent advisory
committees. It is unjustified and nonsensical to attack the FSA’s scientific
reputation and to try to undermine its credibility."
9. The FSA is understood to have briefed its ad agency, United, before
Christmas, and will aim to air ads that are "non-confrontational, humorous and
factual" as a counterweight to industry’s efforts about the same time. The
agency, however, will have a tiny fraction of the budget available to the
industry.
10. Gavin Neath, chairman of Unilever UK and president of the Food and Drink
Federation, has said that the industry has made enormous progress but could not
accept red "stop" signs on its food.
11. Alastair Sykes, chief executive of Nestlé UK, said that under the FSA
proposals all his company’s confectionery and most of its cereals would score a
red. "Are we saying people shouldn’t eat confectionery? We’re driven by
consumers and what they want, and much of what we do has been to make our
products healthier," he said.
12. Chris Wermann, director of communications at Kellogg’s, said: "In
principle we could never accept traffic light labelling."
13. The rival labelling scheme introduced by Kellogg’s, Danone, Unilever,
Nestlé, Kraft and Tesco and now favoured by 21 manufacturers, uses an
industry-devised system based on identifying GDAs of key nutrients. Tesco says
it has tested both traffic lights and GDA labels in its stores and that the
latter increased sales of healthier foods.
14. But the FSA said it could not live with this GDA system alone because it
was "not scientific" or easy for shoppers to understand at a glance.
Questions 1-6
Answer the questions below using NO MORE THAN THREE WORDS from the passage
for each answer.
1. When will instructions be given on reading the color-coded labels?
2. Where can customers find the red light labels?
3. What problem is the FSA trying to handle with the labeling system?
4. Which product sells well but may not be healthy?
5. What information, according to the manufacturers, can be labeled on

1. A European spacecraft took off today to spearhead the search for another
"Earth" among the stars.
2. The Corot space telescope blasted off aboard a Russian Soyuz rocket from
the Baikonur cosmodrome in Kazakhstan shortly after 2.20pm.
3. Corot, short for convection rotation and planetary transits, is the first
instrument capable of finding small rocky planets beyond the solar system. Any
such planet situated in the right orbit stands a good chance of having liquid
water on its surface, and quite possibly life, although a leading scientist
involved in the project said it was unlikely to find "any little green men".
4. Developed by the French space agency, CNES, and partnered by the European
Space Agency (ESA), Austria, Belgium, Germany, Brazil and Spain, Corot will
monitor around 120,000 stars with its 27cm telescope from a polar orbit 514
miles above the Earth. Over two and a half years, it will focus on five to six
different areas of the sky, measuring the brightness of about 10,000 stars every
512 seconds.
5. "At the present moment we are hoping to find out more about the nature of
planets around stars which are potential habitats. We are looking at habitable
planets, not inhabited planets. We are not going to find any little green men,"
Professor Ian Roxburgh, an ESA scientist who has been involved with Corot since
its inception, told the BBC Radio 4 Today programme.
6. Prof Roxburgh said it was hoped Corot would find "rocky planets that could
develop an atmosphere and, if they are the right distance from their parent
star, they could have water".
7. To search for planets, the telescope will look for the dimming of
starlight caused when an object passes in front of a star, known as a "transit".
Although it will take more sophisticated space telescopes planned in the next 10
years to confirm the presence of an Earth-like planet with oxygen and liquid
water, Corot will let scientists know where to point their lenses.
8. Measurements of minute changes in brightness will enable scientists to
detect giant Jupiter-like gas planets as well as small rocky ones. It is the
rocky planets - that could be no bigger than about twice the size of the Earth -
which will cause the most excitement. Scientists expect to find between 10 and
40 of these smaller planets.
9. Corot will also probe into stellar interiors by studying the acoustic
waves that ripple across the surface of stars, a technique called
"asteroseismology".
10. The nature of the ripples allows astronomers to calculate a star’s
precise mass, age and chemical composition.
11. "A planet passing in front of a star can be detected by the fall in light
from that star. Small oscillations of the star also produce changes in the light
emitted, which reveal what the star is made of and how they are structured
internally. This data will provide a major boost to our understanding of how
stars form and evolve," Prof Roxburgh said.
12. Since the discovery in 1995 of the first "exoplanet" - a planet orbiting
a star other than the Sun - more than 200 others have been found by ground-based
observatories.
13. Until now the usual method of finding exoplanets has been to detect the
"wobble" their gravity imparts on parent stars. But only giant gaseous planets
bigger than Jupiter can be found this way, and they are unlikely to harbour
life.
14. In the 2010s, ESA plans to launch Darwin, a fleet of four or five
interlinked space telescopes that will not only spot small rocky planets, but
analyse their atmospheres for signs of biological activity.
15. At around the same time, the US space agency, Nasa, will launch
Terrestrial Planet Finder, another space telescope designed to locate Earth-like
planets.

Don't wash those fossils!
Standard museum practice can wash away DNA.
1.Washing, brushing and varnishing fossils — all standard conservation
treatments used by many fossil hunters and museum curators alike — vastly
reduces the chances of recovering ancient DNA.
2.Instead, excavators should be handling at least some of their bounty with
gloves, and freezing samples as they are found, dirt and all, concludes a paper
in the Proceedings of the National Academy of Sciences today.
3.Although many palaeontologists know anecdotally that this is the best way
to up the odds of extracting good DNA, Eva-Maria Geigl of the Jacques Monod
Institute in Paris, France, and her colleagues have now shown just how important
conservation practices can be.This information, they say, needs to be hammered
home among the people who are actually out in the field digging up bones.
4.Geigl and her colleagues looked at 3,200-year-old fossil bones belonging to
a single individual of an extinct cattle species, called an aurochs.The fossils
were dug up at a site in France at two different times — either in 1947, and
stored in a museum collection, or in 2004, and conserved in sterile conditions
at -20 oC.
5.The team's attempts to extract DNA from the 1947 bones all failed.The newly
excavated fossils, however, all yielded DNA.
6.Because the bones had been buried for the same amount of time, and in the
same conditions, the conservation method had to be to blame says Geigl."As much
DNA was degraded in these 57 years as in the 3,200 years before," she says.
Wash in, wash out
7.Because many palaeontologists base their work on the shape of fossils
alone, their methods of conservation are not designed to preserve DNA, Geigl
explains.
8.The biggest problem is how they are cleaned.Fossils are often washed
together on-site in a large bath, which can allow water — and contaminants in
the form of contemporary DNA — to permeate into the porous bones."Not only is
the authentic DNA getting washed out, but contamination is getting washed in,"
says Geigl.
9.Most ancient DNA specialists know this already, says Hendrik Poinar, an
evolutionary geneticist at McMaster University in Ontario, Canada.But that
doesn't mean that best practice has become widespread among those who actually
find the fossils.
10.Getting hold of fossils that have been preserved with their DNA in mind
relies on close relationships between lab-based geneticists and the excavators,
says palaeogeneticist Svante P bo of the Max Planck Institute for Evolutionary
Anthropology in Leipzig, Germany.And that only occurs in exceptional cases, he
says.
11.P bo's team, which has been sequencing Neanderthal DNA, continually faces
these problems."When you want to study ancient human and Neanderthal remains,
there's a big issue of contamination with contemporary human DNA," he says.
12.This doesn't mean that all museum specimens are fatally flawed, notes P
bo.The Neanderthal fossils that were recently sequenced in his own lab, for
example, had been part of a museum collection treated in the traditional way.But
P bo is keen to see samples of fossils from every major find preserved in line
with Geigl's recommendations — just in case.
Warm and wet
13.Geigl herself believes that, with cooperation between bench and field
researchers, preserving fossils properly could open up avenues of discovery that
have long been assumed closed.
14.Much human cultural development took place in temperate regions.DNA does
not survive well in warm environments in the first place, and can vanish when
fossils are washed and treated.For this reason, Geigl says, most ancient DNA
studies have been done on permafrost samples, such as the woolly mammoth, or on
remains sheltered from the elements in cold caves — including cave bear and
Neanderthal fossils.
15.Better conservation methods, and a focus on fresh fossils, could boost DNA
extraction from more delicate specimens, says Geigl.And that could shed more
light on the story of human evolution.

1.The failure of a high-profile cholesterol drug has thrown a spotlight on
the complicated machinery that regulates cholesterol levels.But many researchers
remain confident that drugs to boost levels of 'good' cholesterol are still one
of the most promising means to combat spiralling heart disease.
2.Drug company Pfizer announced on 2 December that it was cancelling all
clinical trials of torcetrapib，a drug designed to raise heart-protective
high-density lipoproteins (HDLs).In a trial of 15000 patients，a safety board
found that more people died or suffered cardiovascular problems after taking the
drug plus a cholesterol-lowering statin than those in a control group who took
the statin alone.
3.The news came as a kick in the teeth to many cardiologists because earlier
tests in animals and people suggested it would lower rates of cardiovascular
disease."There have been no red flags to my knowledge," says John Chapman，a
specialist in lipoproteins and atherosclerosis at the National Institute for
Health and Medical Research (INSERM) in Paris who has also studied
torcetrapib."This cancellation came as a complete shock."
4.Torcetrapib is one of the most advanced of a new breed of drugs designed to
raise levels of HDLs，which ferry cholesterol out of artery-clogging plaques to
the liver for removal from the body.Specifically，torcetrapib blocks a protein
called cholesterol ester transfer protein (CETP)，which normally transfers the
cholesterol from high-density lipoproteins to low density，plaque-promoting
ones.Statins，in contrast，mainly work by lowering the 'bad' low-density
lipoproteins.
Under pressure
5.Researchers are now trying to work out why and how the drug
backfired，something that will not become clear until the clinical details are
released by Pfizer.One hint lies in evidence from earlier trials that it
slightly raises blood pressure in some patients.It was thought that this mild
problem would be offset by the heart benefits of the drug.But it is possible
that it actually proved fatal in some patients who already suffered high blood
pressure.If blood pressure is the explanation，it would actually be good news for
drug developers because it suggests that the problems are specific to this
compound.Other prototype drugs that are being developed to block CETP work in a
slightly different way and might not suffer the same downfall.
6.But it is also possible that the whole idea of blocking CETP is flawed，says
Moti Kashyap，who directs atherosclerosis research at the VA Medical Center in
Long Beach，California.When HDLs excrete cholesterol in the liver，they actually
rely on LDLs for part of this process.So inhibiting CETP，which prevents the
transfer of cholesterol from HDL to LDL，might actually cause an abnormal and
irreversible accumulation of cholesterol in the body."You're blocking a
physiologic mechanism to eliminate cholesterol and effectively constipating the
pathway," says Kashyap.Going up
7.Most researchers remain confident that elevating high density lipoproteins
levels by one means or another is one of the best routes for helping heart
disease patients.But HDLs are complex and not entirely understood.One approved
drug，called niacin，is known to both raise HDL and reduce cardiovascular risk but
also causes an unpleasant sensation of heat and tingling.Researchers are
exploring whether they can bypass this side effect and whether niacin can lower
disease risk more than statins alone.Scientists are also working on several
other means to bump up high-density lipoproteins by，for example，introducing
synthetic HDLs."The only thing we know is dead in the water is torcetrapib，not
the whole idea of raising HDL," says Michael Miller，director of preventive
cardiology at the University of Maryland Medical Center，Baltimore.

Rogue theory of smell gets a boost
1.A controversial theory of how we smell, which claims that our fine sense of
odour depends on quantum mechanics, has been given the thumbs up by a team of
physicists.
2.Calculations by researchers at University College London (UCL) show that
the idea that we smell odour molecules by sensing their molecular vibrations
makes sense in terms of the physics involved.
3.That's still some way from proving that the theory, proposed in the
mid-1990s by biophysicist Luca Turin, is correct.But it should make other
scientists take the idea more seriously.
4."This is a big step forward," says Turin, who has now set up his own
perfume company Flexitral in Virginia.He says that since he published his
theory, "it has been ignored rather than criticized."
5.Most scientists have assumed that our sense of smell depends on receptors
in the nose detecting the shape of incoming molecules, which triggers a signal
to the brain.This molecular 'lock and key' process is thought to lie behind a
wide range of the body's detection systems: it is how some parts of the immune
system recognise invaders, for example, and how the tongue recognizes some
tastes.
6.But Turin argued that smell doesn't seem to fit this picture very
well.Molecules that look almost identical can smell very different — such as
alcohols, which smell like spirits, and thiols, which smell like rotten eggs.And
molecules with very different structures can smell similar.Most strikingly, some
molecules can smell different — to animals, if not necessarily to humans —
simply because they contain different isotopes (atoms that are chemically
identical but have a different mass).
7.Turin's explanation for these smelly facts invokes the idea that the smell
signal in olfactory receptor proteins is triggered not by an odour molecule's
shape, but by its vibrations, which can enourage an electron to jump between two
parts of the receptor in a quantum-mechanical process called tunnelling.This
electron movement could initiate the smell signal being sent to the brain.
8.This would explain why isotopes can smell different: their vibration
frequencies are changed if the atoms are heavier.Turin's mechanism, says
Marshall Stoneham of the UCL team, is more like swipe-card identification than a
key fitting a lock.
9.Vibration-assisted electron tunnelling can undoubtedly occur — it is used
in an experimental technique for measuring molecular vibrations."The question is
whether this is possible in the nose," says Stoneham's colleague, Andrew
Horsfield.
10.Stoneham says that when he first heard about Turin's idea, while Turin was
himself based at UCL, "I didn't believe it".But, he adds, "because it was an
interesting idea, I thought I should prove it couldn't work.I did some simple
calculations, and only then began to feel Luca could be right." Now Stoneham and
his co-workers have done the job more thoroughly, in a paper soon to be
published in Physical Review Letters.
11.The UCL team calculated the rates of electron hopping in a nose receptor
that has an odorant molecule bound to it.This rate depends on various properties
of the biomolecular system that are not known, but the researchers could
estimate these parameters based on typical values for molecules of this
sort.
12.The key issue is whether the hopping rate with the odorant in place is
significantly greater than that without it.The calculations show that it is —
which means that odour identification in this way seems theoretically
possible.
13.But Horsfield stresses that that's different from a proof of Turin's
idea."So far things look plausible, but we need proper experimental
verification.We're beginning to think about what experiments could be
performed."
14.Meanwhile, Turin is pressing ahead with his hypothesis."At Flexitral we
have been designing odorants exclusively on the basis of their computed
vibrations," he says."Our success rate at odorant discovery is two orders of
magnitude better than the competition." At the very least, he is putting his
money where his nose is.

______.

How shops can exploit people's herd mentality to increase sales
1.A TRIP to the supermarket may not seem like an exercise in psychological
warfare—but it is.Shopkeepers know that filling a store with the aroma of
freshly baked bread makes people feel hungry and persuades them to buy more food
than they had intended.Stocking the most expensive products at eye level makes
them sell faster than cheaper but less visible competitors.Now researchers are
investigating how “swarm intelligence” (that is，how ants，bees or any social
animal，including humans，behave in a crowd) can be used to influence what people
buy.
2.At a recent conference on the simulation of adaptive behaviour in
Rome，Zeeshan-ul-hassan Usmani，a computer scientist from the Florida Institute of
Technology，described a new way to increase impulse buying using this
phenomenon.Supermarkets already encourage shoppers to buy things they did not
realise they wanted: for instance，by placing everyday items such as milk and
eggs at the back of the store，forcing shoppers to walk past other tempting goods
to reach them.Mr Usmani and Ronaldo Menezes，also of the Florida Institute of
Technology，set out to enhance this tendency to buy more by playing on the herd
instinct.The idea is that，if a certain product is seen to be popular，shoppers
are likely to choose it too.The challenge is to keep customers informed about
what others are buying.
3.Enter smart-cart technology.In Mr Usmani's supermarket every product has a
radio frequency identification tag，a sort of barcode that uses radio waves to
transmit information，and every trolley has a scanner that reads this information
and relays it to a central computer.As a customer walks past a shelf of goods，a
screen on the shelf tells him how many people currently in the shop have chosen
that particular product.If the number is high，he is more likely to select it
too.
4.Mr Usmani's “swarm-moves” model appeals to supermarkets because it
increases sales without the need to give people discounts.And it gives shoppers
the satisfaction of knowing that they bought the “right” product—that is，the one
everyone else bought.The model has not yet been tested widely in the real
world，mainly because radio frequency identification technology is new and has
only been installed experimentally in some supermarkets.But Mr Usmani says that
both Wal-Mart in America and Tesco in Britain are interested in his work，and
testing will get under way in the spring.
5.Another recent study on the power of social influence indicates that sales
could，indeed，be boosted in this way.Matthew Salganik of Columbia University in
New York and his colleagues have described creating an artificial music market
in which some 14,000 people downloaded previously unknown songs.The researchers
found that when people could see the songs ranked by how many times they had
been downloaded，they followed the crowd.When the songs were not ordered by
rank，but the number of times they had been downloaded was displayed，the effect
of social influence was still there but was less pronounced.People thus follow
the herd when it is easy for them to do so.
6.In Japan a chain of convenience shops called RanKing RanQueen has been
ordering its products according to sales data from department stores and
research companies.The shops sell only the most popular items in each product
category，and the rankings are updated weekly.Icosystem，a company in
Cambridge，Massachusetts，also aims to exploit knowledge of social networking to
improve sales.
7.And the psychology that works in physical stores is just as potent on the
internet.Online retailers such as Amazon are adept at telling shoppers which
products are popular with like-minded consumers.Even in the privacy of your
home，you can still be part of the swarm.

In the earliest stages of man's development he had nomore need of money than animals have.He was content with very simple forms of shelter,made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him.As he became more civilized,however,he began to want better shelter,more efficient tools and weapons,and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands.For these things he had to turn to the skilled people such as smiths,leather workers or carpenters.It was then that the question of payment arose.
At first he got what he wanted by a simple process ofexchange.The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer inexchange for an axe or a plough.But as more and more goods which had no fixed exchange value came on the market,exchange became too complicated to be satisfactory.Another problem arose when those who made things wanted to get stocks of wood or leather,or iron,but had nothing to offer in exchange until their finished goods were ready. Thus the difficulties of exchange led by degrees to the invention of money.In some countries easily handled things like seeds or shells were given a certain value and the farmer,instead of paying the smith for a new axe by giving him some meat or grain,gave him so many shells.If the smith had any shells left when he had bought his food,he could get stocks of the raw materials of his trade.In some countries quite large things such as cows or camels or even big flat stones were used for trade.Later,pieces of metal,bearing values according to the rarity of the metal and the size of the pieces,or coins were used.Money as we know it had arrived.

Selling Digital Music without Copy-protection Makes Sense
A. It was uncharacteristically low-key for the industry’s greatest showman.
But the essay published this week by Steve Jobs, the boss of Apple, on his
firm’s website under the unassuming title “Thoughts on Music” has nonetheless
provoked a vigorous debate about the future of digital music, which Apple
dominates with its iPod music-player and iTunes music-store. At issue is
“digital rights management” (DRM)—the technology guarding downloaded music
against theft. Since there is no common standard for DRM, it also has the
side-effect that songs purchased for one type of music-player may not work on
another. Apple’s DRM system, called FairPlay, is the most widespread. So it came
as a surprise when Mr. Jobs called for DRM for digital music to be
abolished.
B. This is a change of tack for Apple. It has come under fire from European
regulators who claim that its refusal to license FairPlay to other firms has
“locked in” customers. Since music from the iTunes store cannot be played on
non-iPod music-players (at least not without a lot of fiddling), any iTunes
buyer will be deterred from switching to a device made by a rival firm, such as
Sony or Microsoft. When French lawmakers drafted a bill last year compelling
Apple to open up FairPlay to rivals, the company warned of “state-sponsored
piracy”. Only DRM, it implied, could keep the pirates at bay.
C. This week Mr. Jobs gave another explanation for his former defence of DRM:
the record companies made him do it. They would make their music available to
the iTunes store only if Apple agreed to protect it using DRM. They can still
withdraw their catalogues if the DRM system is compromised. Apple cannot license
FairPlay to others, says Mr Jobs, because it would depend on them to produce
security fixes promptly. All DRM does is restrict consumer choice and provide a
barrier to entry, says Mr Jobs; without it there would be far more stores and
players, and far more innovation. So, he suggests, why not do away with DRM and
sell music unprotected? “This is clearly the best alternative for consumers,” he
declares, “and Apple would embrace it in a heartbeat.”
D. Why the sudden change of heart? Mr Jobs seems chiefly concerned with
getting Europe’s regulators off his back. Rather than complaining to Apple about
its use of DRM, he suggests, “those unhappy with the current situation should
redirect their energies towards persuading the music companies to sell their
music DRM-free.” Two and a half of the four big record companies, he helpfully
points out, are European-owned. Mr Jobs also hopes to paint himself as a
consumer champion. Apple resents accusations that it has become the Microsoft of
digital music.
E. Apple can afford to embrace open competition in music players and online
stores. Consumers would gravitate to the best player and the best store, and at
the moment that still means Apple’s. Mr Jobs is evidently unfazed by rivals to
the iPod. Since only 3% of the music in a typical iTunes library is protected,
most of it can already be used on other players today, he notes. (And even the
protected tracks can be burned onto a CD and then re-ripped.) So Apple’s
dominance evidently depends far more on branding and ease of use than
DRM-related “lock in”.
F. The music giants are trying DRM-free downloads. Lots of smaller labels
already sell music that way. Having seen which way the wind is blowing, Mr Jobs
now wants to be seen not as DRM’s defender, but as a consumer champion who
helped in its downfall. Wouldn’t it lead to a surge in piracy? No, because most
music is still sold unprotected on CDs, people wishing to steal music already
can do so. Indeed, scrapping DRM would probably increase online-music sales by
reducing confusion and incompatibility. With the leading online store, Apple
would benefit most. Mr Jobs’s argument, in short, is transparently self-serving.
It also happens to be right.

new weapon to fight cancer
1. British scientists are preparing to launch trials of a radical new way to
fight cancer, which kills tumours by infecting them with viruses like the common
cold.
2. If successful, virus therapy could eventually form a third pillar
alongside radiotherapy and chemotherapy in the standard arsenal against cancer,
while avoiding some of the debilitating side-effects.
3. Leonard Seymour, a professor of gene therapy at Oxford University, who has
been working on the virus therapy with colleagues in London and the US, will
lead the trials later this year. Cancer Research UK said yesterday that it was
excited by the potential of Prof Seymour’s pioneering techniques.
4. One of the country’s leading geneticists, Prof Seymour has been working
with viruses that kill cancer cells directly, while avoiding harm to healthy
tissue. "In principle, you’ve got something which could be many times more
effective than regular chemotherapy," he said.
5. Cancer-killing viruses exploit the fact that cancer cells suppress the
body’s local immune system. "If a cancer doesn’t do that, the immune system
wipes it out. If you can get a virus into a tumour, viruses find them a very
good place to be because there’s no immune system to stop them replicating. You
can regard it as the cancer’s Achilles’ heel."
6. Only a small amount of the virus needs to get to the cancer. "They
replicate, you get a million copies in each cell and the cell bursts and they
infect the tumour cells adjacent and repeat the process," said Prof Seymour.
7. Preliminary research on mice shows that the viruses work well on tumours
resistant to standard cancer drugs. "It’s an interesting possibility that they
may have an advantage in killing drug-resistant tumours, which could be quite
different to anything we’ve had before."
8. Researchers have known for some time that viruses can kill tumour cells
and some aspects of the work have already been published in scientific journals.
American scientists have previously injected viruses directly into tumours but
this technique will not work if the cancer is inaccessible or has spread
throughout the body.
9. Prof Seymour’s innovative solution is to mask the virus from the body’s
immune system, effectively allowing the viruses to do what chemotherapy drugs do
- spread through the blood and reach tumours wherever they are. The big hurdle
has always been to find a way to deliver viruses to tumours via the bloodstream
without the body’s immune system destroying them on the way.
10. "What we’ve done is make chemical modifications to the virus to put a
polymer coat around it - it’s a stealth virus when you inject it," he said.
11. After the stealth virus infects the tumour, it replicates, but the copies
do not have the chemical modifications. If they escape from the tumour, the
copies will be quickly recognised and mopped up by the body’s immune system.
12. The therapy would be especially useful for secondary cancers, called
metastases, which sometimes spread around the body after the first tumour
appears. "There’s an awful statistic of patients in the west ... with malignant
cancers; 75% of them go on to die from metastases," said Prof Seymour.
13. Two viruses are likely to be examined in the first clinical trials:
adenovirus, which normally causes a cold-like illness, and vaccinia, which
causes cowpox and is also used in the vaccine against smallpox. For safety
reasons, both will be disabled to make them less pathogenic in the trial, but
Prof Seymour said he eventually hopes to use natural viruses.
14. The first trials will use uncoated adenovirus and vaccinia and will be
delivered locally to liver tumours, in order to establish whether the treatment
is safe in humans and what dose of virus will be needed. Several more years of
trials will be needed, eventually also on the polymer-coated viruses, before the
therapy can be considered for use in the NHS. Though the approach will be
examined at first for cancers that do not respond to conventional treatments,
Prof Seymour hopes that one day it might be applied to all cancers.
Questions 1-6
Do the following statements agree with the information given in the reading
passage? For questions 1-6 write
TRUE if the statement agrees with the information
FALSE if the statement contradicts the information
NOT GIVEN if there is no information on this in the passage

2.Cancer Research UK is quite hopeful about Professor Seymour’s work on the
virus therapy.
3.Virus can kill cancer cells and stop them from growing again.
4.Cancer’s Achilles’ heel refers to the fact that virus may stay safely in a
tumor and replicate.
5.To infect the cancer cells, a good deal of viruses should be injected into
the tumor.
6.Researches on animals indicate that virus could be used as a new way to
treat drug-resistant tumors.

How a Frenchman is reviving McDonald’s in Europe
A. When Denis Hennequin took over as the European boss of McDonald’s in
January 2004, the world’s biggest restaurant chain was showing signs of recovery
in America and Australia, but sales in Europe were sluggish or declining. One
exception was France, where Mr Hennequin had done a sterling job as head of the
group’s French subsidiary to sell more Big Macs to his compatriots. His task was
to replicate this success in all 41 of the European countries where
anti-globalisers’ favourite enemy operates.
B. So far Mr Hennequin is doing well. Last year European sales increased by
5.8% and the number of customers by 3.4%, the best annual results in nearly 15
years. Europe accounted for 36% of the group’s profits and for 28% of its sales.
December was an especially good month as customers took to seasonal menu
offerings in France and Britain, and to a promotion in Germany based on the game
of Monopoly.
C. Mr Hennequin’s recipe for revival is to be more open about his company’s
operations, to be “locally relevant”, and to improve the experience of visiting
his 6,400 restaurants. McDonald’s is blamed for making people fat, exploiting
workers, treating animals cruelly, polluting the environment and simply for
being American. Mr Hennequin says he wants to engage in a dialogue with the
public to address these concerns.
D. He introduced “open door” visitor days in each country which became hugely
popular. In Poland alone some 50,000 visitors came to McDonald’s through the
visitors’ programme last year. The Nutrition Information Initiative, launched
last year, put detailed labels on McDonald’s packaging with data on calories,
protein, fat, carbohydrates and salt content. The details are also printed on
tray-liners.
E. Mr Hennequin also wants people to know that “McJobs”, the low-paid menial
jobs at McDonald’s restaurants, are much better than people think. But some of
his efforts have backfired: last year he sparked a controversy with the
introduction of a “McPassport” that allows McDonald’s employees to work anywhere
in the European Union. Politicians accused the firm of a ploy to make cheap
labour from eastern Europe more easily available to McDonald’s managers across
the continent.
F. To stay in touch with local needs and preferences, McDonald’s employs
local bosses as much as possible. A Russian is running McDonald’s in Russia,
though a Serb is in charge of Germany. The group buys mainly from local
suppliers. Four-fifths of its supplies in France come from local farmers, for
example. (Some of the French farmers who campaigned against the company in the
late 1990s subsequently discovered that it was, in fact, buying their produce.)
And it hires celebrities such as Heidi Klum, a German model, as local brand
ambassadors.
G. In his previous job Mr Hennequin established a “design studio” in France
to spruce up his company’s drab restaurants and adapt the interior to local
tastes. The studio is now masterminding improvements everywhere in Europe. He
also set up a “food studio”, where cooks devise new recipes in response to local
trends.
H. Given France’s reputation as the most anti-American country in Europe, it
seems odd that McDonald’s revival in Europe is being led by a Frenchman, using
ideas cooked up in the French market. But France is in fact the company’s most
profitable market after America. The market where McDonald’s is weakest in
Europe is not France, but Britain.
I. “Fixing Britain should be his priority,” says David Palmer, a restaurant
analyst at UBS. Almost two-thirds of the 1,214 McDonald’s restaurants in Britain
are company-owned, compared with 40% in Europe and 15% in America. The company
suffers from the volatility of sales at its own restaurants, but can rely on
steady income from franchisees. So it should sell as many underperforming
outlets as possible, says Mr Palmer.
J. M.Mark Wiltamuth, an analyst at Morgan Stanley, estimates that European
company-owned restaurants’ margins will increase slightly to 16.4% in 2007. This
is still less than in the late 1990s and below America’s 18-19% today. But it is
much better than before Mr Hennequin’s reign. He is already being tipped as the
first European candidate for the group’s top job in Illinois. Nobody would call
that a McJob.

1 There's a dimmer switch inside the sun that causes its brightness to rise
and fall on timescales of around 100,000 years - exactly the same period as
between ice ages on Earth. So says a physicist who has created a computer model
of our star's core.
2 Robert Ehrlich of George Mason University in Fairfax, Virginia, modelled
the effect of temperature fluctuations in the sun's interior. According to the
standard view, the temperature of the sun's core is held constant by the
opposing pressures of gravity and nuclear fusion. However, Ehrlich believed that
slight variations should be possible.
3 He took as his starting point the work of Attila Grandpierre of the Konkoly
Observatory of the Hungarian Academy of Sciences. In 2005, Grandpierre and a
collaborator, Gábor ágoston, calculated that magnetic fields in the sun's core
could produce small instabilities in the solar plasma. These instabilities would
induce localised oscillations in temperature.
4 Ehrlich's model shows that whilst most of these oscillations cancel each
other out, some reinforce one another and become long-lived temperature
variations. The favoured frequencies allow the sun's core temperature to
oscillate around its average temperature of 13.6 million kelvin in cycles
lasting either 100,000 or 41,000 years. Ehrlich says that random interactions
within the sun's magnetic field could flip the fluctuations from one cycle
length to the other.
5 These two timescales are instantly recognisable to anyone familiar with
Earth's ice ages: for the past million years, ice ages have occurred roughly
every 100,000 years. Before that, they occurred roughly every 41,000 years.
6 Most scientists believe that the ice ages are the result of subtle changes
in Earth's orbit, known as the Milankovitch cycles. One such cycle describes the
way Earth's orbit gradually changes shape from a circle to a slight ellipse and
back again roughly every 100,000 years. The theory says this alters the amount
of solar radiation that Earth receives, triggering the ice ages. However, a
persistent problem with this theory has been its inability to explain why the
ice ages changed frequency a million years ago.
7 "In Milankovitch, there is certainly no good idea why the frequency should
change from one to another," says Neil Edwards, a climatologist at the Open
University in Milton Keynes, UK. Nor is the transition problem the only one the
Milankovitch theory faces. Ehrlich and other critics claim that the temperature
variations caused by Milankovitch cycles are simply not big enough to drive ice
ages.
8 However, Edwards believes the small changes in solar heating produced by
Milankovitch cycles are then amplified by feedback mechanisms on Earth. For
example, if sea ice begins to form because of a slight cooling, carbon dioxide
that would otherwise have found its way into the atmosphere as part of the
carbon cycle is locked into the ice. That weakens the greenhouse effect and
Earth grows even colder.
9 According to Edwards, there is no lack of such mechanisms. "If you add
their effects together, there is more than enough feedback to make Milankovitch
work," he says. "The problem now is identifying which mechanisms are at work."
This is why scientists like Edwards are not yet ready to give up on the current
theory. "Milankovitch cycles give us ice ages roughly when we observe them to
happen. We can calculate where we are in the cycle and compare it with
observation," he says. "I can't see any way of testing [Ehrlich's] idea to see
where we are in the temperature oscillation."
10 Ehrlich concedes this. "If there is a way to test this theory on the sun,
I can't think of one that is practical," he says. That's because variation over
41,000 to 100,000 years is too gradual to be observed. However, there may be a
way to test it in other stars: red dwarfs. Their cores are much smaller than
that of the sun, and so Ehrlich believes that the oscillation periods could be
short enough to be observed. He has yet to calculate the precise period or the
extent of variation in brightness to be expected.
11 Nigel Weiss, a solar physicist at the University of Cambridge, is far from
convinced. He describes Ehrlich's claims as "utterly implausible". Ehrlich
counters that Weiss's opinion is based on the standard solar model, which fails
to take into account the magnetic instabilities that cause the temperature
fluctuations.

The Guardian
1. Consumers are to be presented with two rival new year advertising
campaigns as the Food Standards Agency goes public in its battle with the
industry over the labelling of unhealthy foods.
2. The Guardian has learned that the FSA will launch a series of 10-second
television adverts in January telling shoppers how to follow a red, amber and
green traffic light labelling system on the front of food packs, which is
designed to tackle Britain’s obesity epidemic.
3. The campaign is a direct response to a concerted attempt by leading food
manufacturers and retailers, including Kellogg’s and Tesco, to derail the
system. The industry fears that traffic lights would demonise entire categories
of foods and could seriously damage the market for those that are fatty, salty
or high in sugar.
4. The UK market for breakfast cereals is worth ￡1.27bn a year and the
manufacturers fear it will be severely dented if red light labels are put on
packaging drawing attention to the fact that the majority are high in salt
and/or sugar.
5. The industry is planning a major marketing campaign for a competing
labelling system which avoids colour-coding in favour of information about the
percentage of "guideline daily amounts" (GDAs) of fat, salt and sugar contained
in their products.
6. The battle for the nation’s diet comes as new rules on television
advertising come into force in January which will bar adverts for unhealthy
foods from commercial breaks during programmes aimed at children. Sources at the
TV regulators are braced for a legal challenge from the industry and have
described the lobbying efforts to block any new ad ban or colour-coded labelling
as "the most ferocious we’ve ever experienced".
7. Ofcom’s chief executive, Ed Richards, said: "We are prepared to face up to
any legal action from the industry, but we very much hope it will not be
necessary." The FSA said it was expecting an onslaught from the industry in
January. Senior FSA officials said the manufacturers’ efforts to undermine its
proposals on labelling could threaten the agency’s credibility.
8. Terrence Collis, FSA director of communications, dismissed claims that the
proposals were not based on science. "We have some of the most respected
scientists in Europe, both within the FSA and in our independent advisory
committees. It is unjustified and nonsensical to attack the FSA’s scientific
reputation and to try to undermine its credibility."
9. The FSA is understood to have briefed its ad agency, United, before
Christmas, and will aim to air ads that are "non-confrontational, humorous and
factual" as a counterweight to industry’s efforts about the same time. The
agency, however, will have a tiny fraction of the budget available to the
industry.
10. Gavin Neath, chairman of Unilever UK and president of the Food and Drink
Federation, has said that the industry has made enormous progress but could not
accept red "stop" signs on its food.
11. Alastair Sykes, chief executive of Nestlé UK, said that under the FSA
proposals all his company’s confectionery and most of its cereals would score a
red. "Are we saying people shouldn’t eat confectionery? We’re driven by
consumers and what they want, and much of what we do has been to make our
products healthier," he said.
12. Chris Wermann, director of communications at Kellogg’s, said: "In
principle we could never accept traffic light labelling."
13. The rival labelling scheme introduced by Kellogg’s, Danone, Unilever,
Nestlé, Kraft and Tesco and now favoured by 21 manufacturers, uses an
industry-devised system based on identifying GDAs of key nutrients. Tesco says
it has tested both traffic lights and GDA labels in its stores and that the
latter increased sales of healthier foods.
14. But the FSA said it could not live with this GDA system alone because it
was "not scientific" or easy for shoppers to understand at a glance.
Questions 1-6
Answer the questions below using NO MORE THAN THREE WORDS from the passage
for each answer.
1. When will instructions be given on reading the color-coded labels?
2. Where can customers find the red light labels?
3. What problem is the FSA trying to handle with the labeling system?
4. Which product sells well but may not be healthy?
5. What information, according to the manufacturers, can be labeled on
products?
6. What can not be advertised during children’s programmes?

1-7.
NB You may use any letter more than once.
A Ed Richard
B Terrence Collis

D Alastair Sykes
E Chris Wermann
7. Generally we will not agree to use the red light labels.
8. It is unreasonable to doubt if FSA is trustworthy.
9. We are trying to meet our consumers’ needs.
10. The food industry has been improving greatly.
11. The color-coded labeling system is scientific.
12. Our products will be labeled unhealthy by the FSA.

1. A European spacecraft took off today to spearhead the search for another
"Earth" among the stars.
2. The Corot space telescope blasted off aboard a Russian Soyuz rocket from
the Baikonur cosmodrome in Kazakhstan shortly after 2.20pm.
3. Corot, short for convection rotation and planetary transits, is the first
instrument capable of finding small rocky planets beyond the solar system. Any
such planet situated in the right orbit stands a good chance of having liquid
water on its surface, and quite possibly life, although a leading scientist
involved in the project said it was unlikely to find "any little green men".
4. Developed by the French space agency, CNES, and partnered by the European
Space Agency (ESA), Austria, Belgium, Germany, Brazil and Spain, Corot will
monitor around 120,000 stars with its 27cm telescope from a polar orbit 514
miles above the Earth. Over two and a half years, it will focus on five to six
different areas of the sky, measuring the brightness of about 10,000 stars every
512 seconds.
5. "At the present moment we are hoping to find out more about the nature of
planets around stars which are potential habitats. We are looking at habitable
planets, not inhabited planets. We are not going to find any little green men,"
Professor Ian Roxburgh, an ESA scientist who has been involved with Corot since
its inception, told the BBC Radio 4 Today programme.
6. Prof Roxburgh said it was hoped Corot would find "rocky planets that could
develop an atmosphere and, if they are the right distance from their parent
star, they could have water".
7. To search for planets, the telescope will look for the dimming of
starlight caused when an object passes in front of a star, known as a "transit".
Although it will take more sophisticated space telescopes planned in the next 10
years to confirm the presence of an Earth-like planet with oxygen and liquid
water, Corot will let scientists know where to point their lenses.
8. Measurements of minute changes in brightness will enable scientists to
detect giant Jupiter-like gas planets as well as small rocky ones. It is the
rocky planets - that could be no bigger than about twice the size of the Earth -
which will cause the most excitement. Scientists expect to find between 10 and
40 of these smaller planets.
9. Corot will also probe into stellar interiors by studying the acoustic
waves that ripple across the surface of stars, a technique called
"asteroseismology".
10. The nature of the ripples allows astronomers to calculate a star’s
precise mass, age and chemical composition.
11. "A planet passing in front of a star can be detected by the fall in light
from that star. Small oscillations of the star also produce changes in the light
emitted, which reveal what the star is made of and how they are structured
internally. This data will provide a major boost to our understanding of how
stars form and evolve," Prof Roxburgh said.
12. Since the discovery in 1995 of the first "exoplanet" - a planet orbiting
a star other than the Sun - more than 200 others have been found by ground-based
observatories.
13. Until now the usual method of finding exoplanets has been to detect the
"wobble" their gravity imparts on parent stars. But only giant gaseous planets
bigger than Jupiter can be found this way, and they are unlikely to harbour
life.
14. In the 2010s, ESA plans to launch Darwin, a fleet of four or five
interlinked space telescopes that will not only spot small rocky planets, but
analyse their atmospheres for signs of biological activity.
15. At around the same time, the US space agency, Nasa, will launch
Terrestrial Planet Finder, another space telescope designed to locate Earth-like
planets.

Don't wash those fossils!
Standard museum practice can wash away DNA.
1.Washing, brushing and varnishing fossils — all standard conservation
treatments used by many fossil hunters and museum curators alike — vastly
reduces the chances of recovering ancient DNA.
2.Instead, excavators should be handling at least some of their bounty with
gloves, and freezing samples as they are found, dirt and all, concludes a paper
in the Proceedings of the National Academy of Sciences today.
3.Although many palaeontologists know anecdotally that this is the best way
to up the odds of extracting good DNA, Eva-Maria Geigl of the Jacques Monod
Institute in Paris, France, and her colleagues have now shown just how important
conservation practices can be.This information, they say, needs to be hammered
home among the people who are actually out in the field digging up bones.
4.Geigl and her colleagues looked at 3,200-year-old fossil bones belonging to
a single individual of an extinct cattle species, called an aurochs.The fossils
were dug up at a site in France at two different times — either in 1947, and
stored in a museum collection, or in 2004, and conserved in sterile conditions
at -20 oC.
5.The team's attempts to extract DNA from the 1947 bones all failed.The newly
excavated fossils, however, all yielded DNA.
6.Because the bones had been buried for the same amount of time, and in the
same conditions, the conservation method had to be to blame says Geigl."As much
DNA was degraded in these 57 years as in the 3,200 years before," she says.
Wash in, wash out
7.Because many palaeontologists base their work on the shape of fossils
alone, their methods of conservation are not designed to preserve DNA, Geigl
explains.
8.The biggest problem is how they are cleaned.Fossils are often washed
together on-site in a large bath, which can allow water — and contaminants in
the form of contemporary DNA — to permeate into the porous bones."Not only is
the authentic DNA getting washed out, but contamination is getting washed in,"
says Geigl.
9.Most ancient DNA specialists know this already, says Hendrik Poinar, an
evolutionary geneticist at McMaster University in Ontario, Canada.But that
doesn't mean that best practice has become widespread among those who actually
find the fossils.
10.Getting hold of fossils that have been preserved with their DNA in mind
relies on close relationships between lab-based geneticists and the excavators,
says palaeogeneticist Svante P bo of the Max Planck Institute for Evolutionary
Anthropology in Leipzig, Germany.And that only occurs in exceptional cases, he
says.
11.P bo's team, which has been sequencing Neanderthal DNA, continually faces
these problems."When you want to study ancient human and Neanderthal remains,
there's a big issue of contamination with contemporary human DNA," he says.
12.This doesn't mean that all museum specimens are fatally flawed, notes P
bo.The Neanderthal fossils that were recently sequenced in his own lab, for
example, had been part of a museum collection treated in the traditional way.But
P bo is keen to see samples of fossils from every major find preserved in line
with Geigl's recommendations — just in case.
Warm and wet
13.Geigl herself believes that, with cooperation between bench and field
researchers, preserving fossils properly could open up avenues of discovery that
have long been assumed closed.
14.Much human cultural development took place in temperate regions.DNA does
not survive well in warm environments in the first place, and can vanish when
fossils are washed and treated.For this reason, Geigl says, most ancient DNA
studies have been done on permafrost samples, such as the woolly mammoth, or on
remains sheltered from the elements in cold caves — including cave bear and
Neanderthal fossils.
15.Better conservation methods, and a focus on fresh fossils, could boost DNA
extraction from more delicate specimens, says Geigl.And that could shed more
light on the story of human evolution.

1.The failure of a high-profile cholesterol drug has thrown a spotlight on
the complicated machinery that regulates cholesterol levels.But many researchers
remain confident that drugs to boost levels of 'good' cholesterol are still one
of the most promising means to combat spiralling heart disease.
2.Drug company Pfizer announced on 2 December that it was cancelling all
clinical trials of torcetrapib，a drug designed to raise heart-protective
high-density lipoproteins (HDLs).In a trial of 15000 patients，a safety board
found that more people died or suffered cardiovascular problems after taking the
drug plus a cholesterol-lowering statin than those in a control group who took
the statin alone.
3.The news came as a kick in the teeth to many cardiologists because earlier
tests in animals and people suggested it would lower rates of cardiovascular
disease."There have been no red flags to my knowledge," says John Chapman，a
specialist in lipoproteins and atherosclerosis at the National Institute for
Health and Medical Research (INSERM) in Paris who has also studied
torcetrapib."This cancellation came as a complete shock."
4.Torcetrapib is one of the most advanced of a new breed of drugs designed to
raise levels of HDLs，which ferry cholesterol out of artery-clogging plaques to
the liver for removal from the body.Specifically，torcetrapib blocks a protein
called cholesterol ester transfer protein (CETP)，which normally transfers the
cholesterol from high-density lipoproteins to low density，plaque-promoting
ones.Statins，in contrast，mainly work by lowering the 'bad' low-density
lipoproteins.
Under pressure
5.Researchers are now trying to work out why and how the drug
backfired，something that will not become clear until the clinical details are
released by Pfizer.One hint lies in evidence from earlier trials that it
slightly raises blood pressure in some patients.It was thought that this mild
problem would be offset by the heart benefits of the drug.But it is possible
that it actually proved fatal in some patients who already suffered high blood
pressure.If blood pressure is the explanation，it would actually be good news for
drug developers because it suggests that the problems are specific to this
compound.Other prototype drugs that are being developed to block CETP work in a
slightly different way and might not suffer the same downfall.
6.But it is also possible that the whole idea of blocking CETP is flawed，says
Moti Kashyap，who directs atherosclerosis research at the VA Medical Center in
Long Beach，California.When HDLs excrete cholesterol in the liver，they actually
rely on LDLs for part of this process.So inhibiting CETP，which prevents the
transfer of cholesterol from HDL to LDL，might actually cause an abnormal and
irreversible accumulation of cholesterol in the body."You're blocking a
physiologic mechanism to eliminate cholesterol and effectively constipating the
pathway," says Kashyap.Going up
7.Most researchers remain confident that elevating high density lipoproteins
levels by one means or another is one of the best routes for helping heart
disease patients.But HDLs are complex and not entirely understood.One approved
drug，called niacin，is known to both raise HDL and reduce cardiovascular risk but
also causes an unpleasant sensation of heat and tingling.Researchers are
exploring whether they can bypass this side effect and whether niacin can lower
disease risk more than statins alone.Scientists are also working on several
other means to bump up high-density lipoproteins by，for example，introducing
synthetic HDLs."The only thing we know is dead in the water is torcetrapib，not
the whole idea of raising HDL," says Michael Miller，director of preventive
cardiology at the University of Maryland Medical Center，Baltimore.

Rogue theory of smell gets a boost
1.A controversial theory of how we smell, which claims that our fine sense of
odour depends on quantum mechanics, has been given the thumbs up by a team of
physicists.
2.Calculations by researchers at University College London (UCL) show that
the idea that we smell odour molecules by sensing their molecular vibrations
makes sense in terms of the physics involved.
3.That's still some way from proving that the theory, proposed in the
mid-1990s by biophysicist Luca Turin, is correct.But it should make other
scientists take the idea more seriously.
4."This is a big step forward," says Turin, who has now set up his own
perfume company Flexitral in Virginia.He says that since he published his
theory, "it has been ignored rather than criticized."
5.Most scientists have assumed that our sense of smell depends on receptors
in the nose detecting the shape of incoming molecules, which triggers a signal
to the brain.This molecular 'lock and key' process is thought to lie behind a
wide range of the body's detection systems: it is how some parts of the immune
system recognise invaders, for example, and how the tongue recognizes some
tastes.
6.But Turin argued that smell doesn't seem to fit this picture very
well.Molecules that look almost identical can smell very different — such as
alcohols, which smell like spirits, and thiols, which smell like rotten eggs.And
molecules with very different structures can smell similar.Most strikingly, some
molecules can smell different — to animals, if not necessarily to humans —
simply because they contain different isotopes (atoms that are chemically
identical but have a different mass).
7.Turin's explanation for these smelly facts invokes the idea that the smell
signal in olfactory receptor proteins is triggered not by an odour molecule's
shape, but by its vibrations, which can enourage an electron to jump between two
parts of the receptor in a quantum-mechanical process called tunnelling.This
electron movement could initiate the smell signal being sent to the brain.
8.This would explain why isotopes can smell different: their vibration
frequencies are changed if the atoms are heavier.Turin's mechanism, says
Marshall Stoneham of the UCL team, is more like swipe-card identification than a
key fitting a lock.
9.Vibration-assisted electron tunnelling can undoubtedly occur — it is used
in an experimental technique for measuring molecular vibrations."The question is
whether this is possible in the nose," says Stoneham's colleague, Andrew
Horsfield.
10.Stoneham says that when he first heard about Turin's idea, while Turin was
himself based at UCL, "I didn't believe it".But, he adds, "because it was an
interesting idea, I thought I should prove it couldn't work.I did some simple
calculations, and only then began to feel Luca could be right." Now Stoneham and
his co-workers have done the job more thoroughly, in a paper soon to be
published in Physical Review Letters.
11.The UCL team calculated the rates of electron hopping in a nose receptor
that has an odorant molecule bound to it.This rate depends on various properties
of the biomolecular system that are not known, but the researchers could
estimate these parameters based on typical values for molecules of this
sort.
12.The key issue is whether the hopping rate with the odorant in place is
significantly greater than that without it.The calculations show that it is —
which means that odour identification in this way seems theoretically
possible.
13.But Horsfield stresses that that's different from a proof of Turin's
idea."So far things look plausible, but we need proper experimental
verification.We're beginning to think about what experiments could be
performed."
14.Meanwhile, Turin is pressing ahead with his hypothesis."At Flexitral we
have been designing odorants exclusively on the basis of their computed
vibrations," he says."Our success rate at odorant discovery is two orders of
magnitude better than the competition." At the very least, he is putting his
money where his nose is.

______.

really occur in human nose.

How shops can exploit people's herd mentality to increase sales
1.A TRIP to the supermarket may not seem like an exercise in psychological
warfare—but it is.Shopkeepers know that filling a store with the aroma of
freshly baked bread makes people feel hungry and persuades them to buy more food
than they had intended.Stocking the most expensive products at eye level makes
them sell faster than cheaper but less visible competitors.Now researchers are
investigating how “swarm intelligence” (that is，how ants，bees or any social
animal，including humans，behave in a crowd) can be used to influence what people
buy.
2.At a recent conference on the simulation of adaptive behaviour in
Rome，Zeeshan-ul-hassan Usmani，a computer scientist from the Florida Institute of
Technology，described a new way to increase impulse buying using this
phenomenon.Supermarkets already encourage shoppers to buy things they did not
realise they wanted: for instance，by placing everyday items such as milk and
eggs at the back of the store，forcing shoppers to walk past other tempting goods
to reach them.Mr Usmani and Ronaldo Menezes，also of the Florida Institute of
Technology，set out to enhance this tendency to buy more by playing on the herd
instinct.The idea is that，if a certain product is seen to be popular，shoppers
are likely to choose it too.The challenge is to keep customers informed about
what others are buying.
3.Enter smart-cart technology.In Mr Usmani's supermarket every product has a
radio frequency identification tag，a sort of barcode that uses radio waves to
transmit information，and every trolley has a scanner that reads this information
and relays it to a central computer.As a customer walks past a shelf of goods，a
screen on the shelf tells him how many people currently in the shop have chosen
that particular product.If the number is high，he is more likely to select it
too.
4.Mr Usmani's “swarm-moves” model appeals to supermarkets because it
increases sales without the need to give people discounts.And it gives shoppers
the satisfaction of knowing that they bought the “right” product—that is，the one
everyone else bought.The model has not yet been tested widely in the real
world，mainly because radio frequency identification technology is new and has
only been installed experimentally in some supermarkets.But Mr Usmani says that
both Wal-Mart in America and Tesco in Britain are interested in his work，and
testing will get under way in the spring.
5.Another recent study on the power of social influence indicates that sales
could，indeed，be boosted in this way.Matthew Salganik of Columbia University in
New York and his colleagues have described creating an artificial music market
in which some 14,000 people downloaded previously unknown songs.The researchers
found that when people could see the songs ranked by how many times they had
been downloaded，they followed the crowd.When the songs were not ordered by
rank，but the number of times they had been downloaded was displayed，the effect
of social influence was still there but was less pronounced.People thus follow
the herd when it is easy for them to do so.
6.In Japan a chain of convenience shops called RanKing RanQueen has been
ordering its products according to sales data from department stores and
research companies.The shops sell only the most popular items in each product
category，and the rankings are updated weekly.Icosystem，a company in
Cambridge，Massachusetts，also aims to exploit knowledge of social networking to
improve sales.
7.And the psychology that works in physical stores is just as potent on the
internet.Online retailers such as Amazon are adept at telling shoppers which
products are popular with like-minded consumers.Even in the privacy of your
home，you can still be part of the swarm.

In the earliest stages of man's development he had nomore need of money than animals have.He was content with very simple forms of shelter,made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him.As he became more civilized,however,he began to want better shelter,more efficient tools and weapons,and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands.For these things he had to turn to the skilled people such as smiths,leather workers or carpenters.It was then that the question of payment arose.
At first he got what he wanted by a simple process ofexchange.The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer inexchange for an axe or a plough.But as more and more goods which had no fixed exchange value came on the market,exchange became too complicated to be satisfactory.Another problem arose when those who made things wanted to get stocks of wood or leather,or iron,but had nothing to offer in exchange until their finished goods were ready. Thus the difficulties of exchange led by degrees to the invention of money.In some countries easily handled things like seeds or shells were given a certain value and the farmer,instead of paying the smith for a new axe by giving him some meat or grain,gave him so many shells.If the smith had any shells left when he had bought his food,he could get stocks of the raw materials of his trade.In some countries quite large things such as cows or camels or even big flat stones were used for trade.Later,pieces of metal,bearing values according to the rarity of the metal and the size of the pieces,or coins were used.Money as we know it had arrived.

Itwasuncharacteristicallylow-keyfortheindustry’sgreatestshowman.ButtheessaypublishedthisweekbySteveJobs,thebossofApple,onhisfirm’swebsiteundertheunassumingtitle“ThoughtsonMusic”hasnonethelessprovokedavigorousdebateaboutthefutureofdigitalmusic,whichAppledominateswithitsiPodmusic-playerandiTunesmusic-store.Atissueis“digitalrightsmanagement”(DRM)—thetechnologyguardingdownloadedmusicagainsttheft.SincethereisnocommonstandardforDRM,italsohastheside-effectthatsongspurchasedforonetypeofmusic-playermaynotworkonanother.Apple’sDRMsystem,calledFairPlay,isthemostwidespread.SoitcameasasurprisewhenMr.JobscalledforDRMfordigitalmusictobeabolished.
B. ThisisachangeoftackforApple.IthascomeunderfirefromEuropeanregulatorswhoclaimthatitsrefusaltolicenseFairPlaytootherfirmshas“lockedin”customers.SincemusicfromtheiTunesstorecannotbeplayedonnon-iPodmusic-players(atleastnotwithoutalotoffiddling),anyiTunesbuyerwillbedeterredfromswitchingtoadevicemadebyarivalfirm,suchasSonyorMicrosoft.WhenFrenchlawmakersdraftedabilllastyearcompellingAppletoopenupFairPlaytorivals,thecompanywarnedof“state-sponsoredpiracy”.OnlyDRM,itimplied,couldkeepthepiratesatbay.
C. ThisweekMr.JobsgaveanotherexplanationforhisformerdefenceofDRM:therecordcompaniesmadehimdoit.TheywouldmaketheirmusicavailabletotheiTunesstoreonlyifAppleagreedtoprotectitusingDRM.TheycanstillwithdrawtheircataloguesiftheDRMsystemiscompromised.ApplecannotlicenseFairPlaytoothers,saysMrJobs,becauseitwoulddependonthemtoproducesecurityfixespromptly.AllDRMdoesisrestrictconsumerchoiceandprovideabarriertoentry,saysMrJobs;withoutittherewouldbefarmorestoresandplayers,andfarmoreinnovation.So,hesuggests,whynotdoawaywithDRMandsellmusicunprotected?“Thisisclearlythebestalternativeforconsumers,”hedeclares,“andApplewouldembraceitinaheartbeat.”
D. Whythesuddenchangeofheart?MrJobsseemschieflyconcernedwithgettingEurope’sregulatorsoffhisback.RatherthancomplainingtoAppleaboutitsuseofDRM,hesuggests,“thoseunhappywiththecurrentsituationshouldredirecttheirenergiestowardspersuadingthemusiccompaniestoselltheirmusicDRM-free.”Twoandahalfofthefourbigrecordcompanies,hehelpfullypointsout,areEuropean-owned.MrJobsalsohopestopainthimselfasaconsumerchampion.AppleresentsaccusationsthatithasbecometheMicrosoftofdigitalmusic.
E. Applecanaffordtoembraceopencompetitioninmusicplayersandonlinestores.Consumerswouldgravitatetothebestplayerandthebeststore,andatthemomentthatstillmeansApple’s.MrJobsisevidentlyunfazedbyrivalstotheiPod.Sinceonly3%ofthemusicinatypicaliTuneslibraryisprotected,mostofitcanalreadybeusedonotherplayerstoday,henotes.(AndeventheprotectedtrackscanbeburnedontoaCDandthenre-ripped.)SoApple’sdominanceevidentlydependsfarmoreonbrandingandeaseofusethanDRM-related“lockin”.
F. ThemusicgiantsaretryingDRM-freedownloads.Lotsofsmallerlabelsalreadysellmusicthatway.Havingseenwhichwaythewindisblowing,MrJobsnowwantstobeseennotasDRM’sdefender,butasaconsumerchampionwhohelpedinitsdownfall.Wouldn’titleadtoasurgeinpiracy?No,becausemostmusicisstillsoldunprotectedonCDs,peoplewishingtostealmusicalreadycandoso.Indeed,scrappingDRMwouldprobablyincreaseonline-musicsalesbyreducingconfusionandincompatibility.Withtheleadingonlinestore,Applewouldbenefitmost.MrJobs’sargument,inshort,istransparentlyself-serving.Italsohappenstoberight.
