What has happened to Nasa's missing Moon rocks?

What has happened to Nasa's missing Moon rocks?

The US space agency Nasa recently announced that many of the Moon rocks brought back to Earth from two Apollo space missions have gone missing. They were given as gifts to the nations of the world. So what happened to them?

Towards the end of the Apollo 17 mission on 13 December 1972, Eugene Cernan and Harrison Schmitt - the last men to have set foot on the Moon - picked up a rock.

Cernan announced: "We'd like to share a piece of this rock with so many of the countries throughout the world."

His wish was fulfilled.

President Richard Nixon ordered that the brick-sized rock be broken up into fragments and sent to 135 foreign heads of state and the 50 US states.

Each "goodwill Moon rock" was encased in a lucite ball and mounted on a wooden plaque with the recipient nations' flag attached.

Moon rock collected during the Apollo 11 mission in 1969 was also distributed to the same nations and US states.

There were 370 pieces gathered for this purpose from the two missions. Two hundred and seventy were given to nations of the world and 100 to the 50 US states.

But 184 of these are lost, stolen or unaccounted for - 160 around the world and 24 in the US.

The rocks were distributed to countries ranging from Afghanistan to Trinidad and Tobago.

Joseph Gutheinz Joseph Gutheinz's search for the missing Moon rocks began in 1998

"Gaddafi's government was given two Moon rocks - they're missing. Romania is missing its Apollo 17 goodwill Moon rock," says Joseph Gutheinz Jr, the Texas-based lawyer and former Nasa agent, who has become known as the "Moon rock hunter".

His obsession began in 1998 when - still at Nasa - he set up an undercover sting operation called Operation Lunar Eclipse.

He placed an advert entitled "Moon Rocks Wanted" in USA Today, to entice con-artists selling bogus Moon rocks to approach him.

"What I did not anticipate was that a person with the real thing, the Honduras goodwill Moon rock, would call me," he says.

The rock - which weighed 1.142g - was offered to Gutheinz for $5m (£3m).

He did not pay the money, but says the asking price was reasonable.

These valuable rocks are not being protected as well as they could be, he says, and both Nasa and the recipient nations have done a poor job of entering them into an inventory system.

He says the only authorised sale of lunar material that he is aware of was in 1993, when the Russian government sold material gathered from the Soviet Union's Luna 16 mission at Sotheby's auction house in New York.

From lunar landscape to Dublin dump

Dr Ian Elliott worked at the Dunsink Observatory in Dublin when it was destroyed by fire on 3 October 1977.

I heard about the fire on the morning news. I can tell you, that was a bit of a shock.

My main concern was with the disruption to the work of the observatory. It was only afterwards that we realised that the bit of Apollo 11 Moon rock could not be found.

It was gathered up with all of the other debris and dumped in the municipal dump which was conveniently just across the road.

It is probably the only municipal dump in the world that has got a bit of Moon rock.

If we'd had any perception of the rock's value, perhaps all of the debris would have been sifted by archaeologists and it might have been found.

I am amazed that anyone puts a value of $5m on it, though there are a lot of mad people with money around so they might just pay that.

It is a very big dump, I am afraid. It is worse than a needle in a haystack - you would never find it.

An anonymous private collector bought 0.2g of lunar dust for $442,500 (£280,000).

With potential prices in this range, it is no surprise there is a lucrative black market in moon rocks, both real and fake.

Mr Gutheinz says a woman in California allegedly tried to sell a Moon rock online, and that attempts to sell Spain's and Cyprus's moon rocks have been well documented.

"I once offered $10,000 for the recovery of Malta's stolen Apollo 17 goodwill Moon rock but it still hasn't been recovered," he says.

"I know for certain that this was an amateur thief as he only took the rocks, and not the self-authenticating plaque."

Some Moon rocks have gone astray at times of revolution or political transition. The US national archives show that a rock was presented to the late Romanian dictator, Nicolae Ceausescu, but Gutheinz believes it was sold after his execution.

Then there is the mysterious tale of how - after a fire at an observatory in Dublin - Ireland's Apollo 11 Moon rock ended up lying in a rubbish dump, after apparently being thrown out with the rest of the debris.

"It's still there under a couple of tonnes of trash. That could definitely be worth over $5m (£3.1m). I'll tell you where it's at. It's in the Finglas landfill dump in Dublin," Gutheinz says.

Because of the scale of the task he has challenged his students at the University of Phoenix and Alvin Community College in Texas - where he teaches criminal justice - to help find the missing rocks.

So far, they have helped to track down 77, including those that were given to the governors of the US states of Colorado, Missouri and West Virginia.

Dr Carle Pieters, a planetary geologist at Brown University, Rhode Island, says the knowledge gained from these tiny rocks is priceless.

"I am continually awed when I work with four-billion-year-old lunar samples. They are beautiful and don't have ugly weathering products often seen in Earth rocks.

"The lunar rocks retain a record of events in the early solar system that we cannot obtain elsewhere."

While Joseph Gutheinz has compared them to works of art, not everyone is so enthusiastic about them. London-based art writer and curator, Francesca Gavin, describes them as "ugly little things", although she is not opposed to the idea of seeing one in an art gallery.

"Moon rocks could be seen as artworks - relating in particular to the Chinese tradition of the Philosopher Stones as naturally occurring artworks reflecting the universe in microcosmic form," she says.

Gavin does not think the rocks are worth $5m (£3.1m), however, and questions the way they are mounted as goodwill gifts.

"The brown plaque, text and flag? It's pretty uneasy on the eyes."

Gutheinz concedes he will never be able to recover all of the missing Moon rocks - many are now in private collections - but says there are some he particularly wants back.

"Definitely the Malta Moon rock. I'd really like to see that back, and the Romanian rock. If I go to Europe, I will hunt that one down. I have a few ideas as to how I'll do that.

"And I love the story about the Ireland Moon rock - that pot of gold under a dump."

Doctors want to improve the prognosis of this aggressive cancer

Scientists say they may have found a new weapon against pancreatic cancer after promising early trial results of an experimental drug combination.

Giving the chemotherapy agent gemcitabine with an experimental drug called MRK003 sets off a chain of events that ultimately kills cancer cells, studies in mice show.

Patients are now testing the treatment to see if it will work for them.

The Cancer Research UK-funded trials are being carried out in Cambridge.

Father-of-two Richard Griffiths, 41, from Coventry, has been on the trial since being diagnosed with pancreatic cancer in May 2011.

"After six cycles of treatment, a scan showed the tumours had reduced and so I have continued with the treatment," he said.

"The trial gives you hope - I really feel I can do this with the science behind me."

Aggressive cancer

Cancer Research UK says it is prioritising research into pancreatic cancer because the survival rate still remains dismally low.

About 8,000 people in the UK are diagnosed with pancreatic cancer each year, and the disease is the fifth most common cause of cancer death in the UK.

Survival rates are very low in relation to other cancers, and the length of time between diagnosis and death is typically short, usually less than six months.

The most recent data for England show that about 16% of patients survive the disease beyond 12 months after diagnosis - prompting the need for new treatments.

Professor Duncan Jodrell, who is leading the trials at the University of Cambridge, said: "We're delighted that the results of this important research are now being evaluated in a clinical trial, to test whether this might be a new treatment approach for patients with pancreatic cancer, although it will be some time before we're able to say how successful this will be in patients."

In total, about 60 patients with advanced pancreatic cancer will be recruited for the first Phase I/II clinical trial.

The cult of the hyperpolyglot

The cult of the hyperpolyglot

Alex Rawlings demonstrates his 11 languages

Many people want to speak a second language, but for some people two can never be enough. Welcome to the world of the hyperpolyglot.

Ray Gillon speaks 18 languages. To be precise, he only speaks eight fluently. His grasp on the other 10 is merely conversational.

Throw anything at him in Portuguese, Thai, Turkish, Russian, Polish, Dutch, Danish, Norwegian, Bulgarian or Mandarin and he will banter back.

In the UK, where there has been a growing anxiety over the failure to learn additional languages, Gillon might seem to be a bit of an anomaly. More and more children have been giving up languages since the last government made learning foreign languages optional in England from the age of 14.

Publisher HarperCollins has been searching for the UK's most multilingual student, and has discovered a 20-year-old Oxford University undergraduate who can speak 11 languages. And a new book, Babel No More: The Search for the World's Most Extraordinary Language Learners, by Michael Erard, suggests Gillon is among a set of people who are learning languages for fun.

Ray Gillon Ray Gillon says he sees etymology as a sport and he enjoys looking up the origins of words

So what makes some people learn language after language?

For self-taught polyglot Gillon, 54, his love affair with language started by accident. He says he first learned French and Latin at the age of 11, and later studied French and German as elective courses while studying for his electronic engineering degree.

"But it wasn't until I got my first job, and was sent to live in the south of France, that I had any real enthusiasm for languages," he says.

It was during this chapter of his life, while designing audio visual systems for a cruise liner, that Gillon was introduced to Italian through colleagues.

What's that you're saying?

Beatles promote multi-language version of their song All You Need Is Love
  • Up to 7,000 different languages are estimated to be spoken around the world
  • Mandarin Chinese, English, Spanish, Hindi, Arabic, Bengali, Russian, Portuguese, Japanese, German and French are world's most widely spoken languages, according to UNESCO
  • Languages are grouped into families that share a common ancestry
  • English is related to German and Dutch, and all are part of Indo-European family of languages
  • Also includes French, Spanish and Italian, which come from Latin
  • 2,200 of the world's languages can be found in Asia, while Europe has 260

Source: BBC Languages

"I went to Italy for a weekend, and fell in love with the language. I bought books and started teaching myself. By the end of my three years in France, I was fluent in both languages," he says.

Gillon's next job took him round the world, and pretty soon he was up to speed on German, Spanish, Polish, Portuguese and Swedish.

He says he used half a dozen languages every day for 10 years and his current job, which involves supervising foreign language versioning of Hollywood movies, means he has to stay on top of his skills.

"I have a massive foreign language book library, so I regularly keep up to date, revising grammar, reading newspapers, watching satellite television.

"My much better half is also Swedish and speaks six languages - we probably speak them all every day," he says.

According to author and linguistics expert Erard, there are not many hyperpolyglots like Gillon in the world. He has identified 11 languages as a significant watershed. Those who speak more than this are very rare.

But he says it is difficult to define hyperpolyglots and polyglots because essentially it has to be about speaking and knowing rather than reading and writing. In some cases literacy is not possible, or a language does not have an alphabet.

He says the question of "how much a language weighs" is also significant in determining how unusual a linguist is.

Rise of the polyglots

"Most people say it's easier to pick up languages when you're younger," says David Green, of University College London, who specialises in bilingualism.

"But people can learn languages at any point in their lives. Being immersed in a language is important. Personality is a contributing factor too - not being able to tolerate feeling foolish from making inevitable errors will make learning a new language a difficult process.

"Polyglots are definitely on the rise worldwide predominantly because of migration. In 10 years' time, it is estimated that 50% of America will be Spanish-speaking. Many of these people will speak both English and Spanish."

"If the languages are English, French, Mandarin, Japanese, Hindi and Russian - that would be more significant from a learner's perspective than 11 Romance languages such as Italian, French and Spanish," he says.

People who are gifted linguists also often have to make the choice between getting very highly developed skills in a smaller number of languages, or focusing on one aspect like the oral language, he says.

For language-lover Matt Withers, 32, who speaks German, Portuguese, Luxembourgish, French and Welsh, it is not his vocation, but a fascination with language and the world that fuels his hobby.

But rather than relying solely on books, he also signed up to a series of courses.

"When I lived in Germany, I shared a house with three Brazilians, so I did an evening course in Portuguese to converse with them - it was interesting trying to learn Portuguese through the medium of German," he laughs.

Which words come easily?

Road signs in English and Polish
  • Usually easier when second language is close to learner's native tongue in terms of vocabulary, sounds or sentence structure
  • So Polish speakers find it easier to learn Slavic languages like Czech rather than Asian ones
  • And Japanese speakers will find it easier to learn Mandarin than Polish
  • Easiest language for native English speakers to learn is said to be Dutch
  • Five most difficult languages for native English speakers are Arabic, Cantonese, Mandarin, Japanese and Korean

Source: BBC Languages

"For the past few years, I've been living in Wales - I share an office with predominantly native Welsh speakers, so I've been learning Welsh."

Withers thinks that fluency in one language allows people to accumulate others more easily.

"Most monoglots in this country aren't really able to explain English in terms such as the perfect past tense and past tense. When you learn about cases and tenses and grammatical formations, I think the tool box is there for other languages," he says.

But he concedes it is not always the case, "as Welsh isn't like any other major European language, in terms of the way it is constructed, and is incredibly different".

So what enables hyperpolyglots to seemingly pick up a new language at the push of a button?

Erard says it is hard to explain, but whatever an individual's biographical reasons are, he believes there is something that distinguishes hyperpolyglots neurologically.

"They have a neurological hardware that responds to the world, that's fed by the world, that is suited to a pattern that is recognition-heavy, sound-heavy and memory-heavy - that is very structured, and also very sociable.

Manuel from Fawlty Towers Manuel probably spoke three languages - Basil Fawlty just the one

"They have an ability to switch between languages very easily, and that involves cognitive skills which are often heritable," he adds.

But Gillon says he has no idea what the secret to his success is.

He says some "blocks" - Germanic, Slavic, Latin - make it "easier to go with the flow, and language becomes intuitive". He agrees that by the third or fourth language, it also gets easier to assimilate vocabulary and grammar much more quickly.

"Etymology is a sport for me. I enjoy looking up the origin of words and seeing which particular invasion was responsible for bringing that word into our vocabulary. I am immersed in it for my work and it will continue to intrigue me for every day of my life."

But he concludes: "I can't explain it - if I could, I would bottle and sell it."

Dolphins deserve same rights as humans, say scientists

Dolphins deserve same rights as humans, say scientists

Recognising the rights of dolphins would end whaling and their captivity

Dolphins should be treated as non-human "persons", with their rights to life and liberty respected, scientists meeting in Canada have been told.

Experts in philosophy, conservation and animal behaviour want support for a Declaration of Rights for Cetaceans.

They believe dolphins and whales are sufficiently intelligent to justify the same ethical considerations as humans.

Recognising their rights would mean an end to whaling and their captivity, or their use in entertainment.

“Start Quote

Science has shown that individuality - consciousness, self-awareness - is no longer a unique human property. That poses all kinds of challenges.”

Ethics Professor Tom White Loyola Marymount University of Los Angeles

The move was made at the annual meeting of the American Association for the Advancement of Science (AAAS) in Vancouver, Canada, the world's biggest science conference.

It is based on years of research that has shown dolphins and whales have large, complex brains and a human-like level of self-awareness.

This has led the experts to conclude that although non-human, dolphins and whales are "people" in a philosophical sense, which has far-reaching implications.

'Self-aware'

Ethics expert Prof Tom White, from Loyola Marymount University, Los Angeles, author of In Defence of Dolphins: The New Moral Frontier, said dolphins were "non-human persons".

"A person needs to be an individual. If individuals count, then the deliberate killing of individuals of this sort is ethically the equivalent of deliberately killing a human being.

Intelligent cetacean behaviour

  • A member of a group of orcas, or killer whales, in Patagonia had a damaged jaw and could not feed. The elderly whale was fed and kept alive by its companions.
  • Dolphins taking part in an experiment had to press one of two levers to distinguish between sounds, some of which were very similar. By pressing a third lever, they were able to tell the researchers they wanted to "pass" on a particular test because it was too hard. "When you place dolphins in a situation like that they respond in exactly the same way humans do," said Dr Lori Marino. "They are accessing their own minds and thinking their own thoughts."
  • A number of captive dolphins were rewarded with fish in return for tidying up their tank. One of them ripped up a large paper bag, hid away the pieces, and presented them one at a time to get multiple rewards.
  • In Iceland, killer whales and fishermen have been known to work together. The whales show the fishermen where to lay their nets, and in return are allowed to feed on part of the catch. Then they lead the fleet to the next fishing ground.

"We're saying the science has shown that individuality - consciousness, self-awareness - is no longer a unique human property. That poses all kinds of challenges."

They can look in a mirror and say, 'Hey, that's me'”

Dr Lori Marino Psychologist

The declaration, originally agreed in May 2010, contains the statements "every individual cetacean has the right to life", "no cetacean should be held in captivity or servitude, be subject to cruel treatment, or be removed from their natural environment", and "no cetacean is the property of any state, corporation, human group or individual".

It adds: "The rights, freedoms and norms set forth in this declaration should be protected under international and domestic law."

Psychologist Dr Lori Marino, from Emory University in Atlanta, told how scientific advances had changed the view of the cetacean brain.

She said: "We went from seeing the dolphin/whale brain as being a giant amorphous blob that doesn't carry a lot of intelligence and complexity to not only being an enormous brain but an enormous brain with an enormous amount of complexity, and a complexity that rivals our own."

Dolphins had a sense of self which could be tested by the way they recognise themselves in mirrors, she added.

"When you get up in the morning and look in the mirror and know that's you, you have a sense of 'you'," said Dr Marino.

"They have a similar sense. They can look in a mirror and say, 'Hey, that's me'."

10 radical solutions to binge drinking

10 radical solutions to binge drinking

Man drinks wine while cooking

Related Stories

Pressure to address the UK's binge drinking grows ever stronger, with a number of radical solutions being put forward to try to help people cut down.

David Cameron last week called binge drinking a "scandal" that costs the NHS £2.7bn a year. He pledged to introduce drunk tanks and booze buses, and there are plans for a minimum price for alcohol.

So what are the most radical solutions to the problem?

Subtly make drinks weaker

Definition of binge drinking

  • For men, more than eight units of alcohol - or about three pints of strong beer
  • For women, more than six units of alcohol, equivalent to three small (175ml) glasses of wine

Food firms have recently moved to cut the amount of salt and saturated fat in their products, following government pressure. The British Medical Association wants to see the same thing happen in relation to beer. So, for example, a premium lager could gradually be reduced from 5.5% to 5%, while a bitter comes down from 4.5% to 4%.

But Roger Protz, editor of the Good Beer Guide, says beer in Britain is much weaker than in the rest of Europe. And to reduce it would affect its characteristic flavour. "London Pride [bitter] at 4.1% is a lovely malty, hoppy beer but if you reduce it to 3.5% it will be very different."

Another approach would be to use the tax system to target stronger drinks. The March 2011 budget saw a rise in the duty on strong beers (above 7.5% alcohol) of 25%, and the duty on weak beers (below 2.8%) cut by 50%. Alcohol Concern says this should be extended to wine, which is getting stronger.

The British Beer and Pub Association says the current focus on beer is wrong. "We should be encouraging people to drink more beer rather than stronger drinks, which have been gaining market share. Beer tax here is 12 times that of Germany."

Enforce a minimum price for alcohol

Man carrying recycling box full of empty wine and beer bottles Many find it cheaper to drink at home

A review of international research published last year by Bangor University found that pricing was the "key determinant" for how much people drank.

Alcohol Concern wants to see a minimum rate of 50p per unit of alcohol brought in. It would make a pint of beer at least £1.25 and a bottle of wine £5.

It would hit the low-cost retailers rather than bars and restaurants, says Andrew Misell, a spokesman for Alcohol Concern. "It won't affect pub prices. Where you will be hit hard is in the supermarkets where cider is on sale for as little as 13p a unit."

The drinks industry says such moves only encourage counterfeit and smuggled alcohol. And Tim Martin, founder of JD Wetherspoon, says consumers will simply go abroad. "It's an international industry. People can go to Calais and load up their car with as much alcohol as they want."

Jamie Bartlett, author of Under the Influence, a 2011 report on binge drinking for think tank Demos, says it would cut total alcohol consumption but not necessarily binges. "The problem is people going on benders and it's not clear it would have an impact on that."

Get people back into pubs

Barbara Windsor in a pub, 1963 Pubs are dying out but are they a safer place to drink?

One of the traditional roles of the pub landlord is to tell a drinker when they've had enough. No such authority figure exists in people's living rooms. And pubs are closing in great numbers across the country, as supermarket-bought booze now accounts for about half of what's being consumed.

So, one solution is to shift drinking back into the pub where it is typically more expensive, served in measurable quantities, and supervised by trained staff. Martin says this can be done by cutting VAT on food and alcohol in pubs to 5%, a proposal that has been successful in helping restaurants in France and Ireland. Supermarkets add no VAT on to the food they sell, whereas pubs have VAT of 20%. "Supermarkets are effectively cross subsidising alcohol sales with their food sales. It's a huge tax advantage that undermines pubs," Martin says.

The British Medical Association does not accept that pubs should be cheaper but agrees that shop-bought drink should be made more expensive - "thus encouraging alcohol to be consumed in pubs where there are more controls". Misell cautions against getting too nostalgic about a golden age of pub sobriety that never was. "Some people idolise the pub as this place where it's impossible to get drunk. And yet we all know it's perfectly possible to over-indulge there."

Raise the legal drinking age

Empties in a park

In the US, the legal drinking age is 21. And there's an argument that by raising the minimum age, it makes it easier for retailers to police under-age drinking - most 21-year-olds look like adults. While raising the minimum age is not official BMA policy, the doctors' body argues that it is something that could be explored. A spokeswoman suggests: "Evidence from America clearly demonstrates that raising the legal drinking age has a significant positive effect on alcohol-related problems." Alcohol Concern agrees but says it would be politically impossible to raise the drinking age.

Tim Martin says that teenagers are going to try to drink, regardless of the law. The key thing is that they start by drinking beer in pubs, under the "watchful eye" of the landlord rather than vodka somewhere else. It's time the government stopped trying to entrap landlords by hiring 15 and 16-year-olds to try to get served.

Off-licences are rarely prosecuted for selling to under 18s, as it is, says Bartlett. So to raise the age limit even higher would not make sense. "Last year I think only one off-licence was fined for selling alcohol to a minor," says Bartlett.

The drinks industry says the issue of under-age drinking is already taken seriously in shops. For instance, under the Challenge 25 scheme shoppers are warned that if they look under 25 they may have to show ID, says Richard Dodd, spokesman for the British Retail Consortium. It raises the question of why this is not rolled out everywhere, as happens in countries like Sweden.

Nationalise off-licences

In some places - most of Canada, certain US States and Sweden - only certain state-owned shops can sell alcohol. The most rigorous is Sweden.

To buy a bottle of wine in Sweden, it's necessary to visit one of the country's network of Systembolaget shops, which close on Saturday afternoons and do not open on Sundays. The approach prevents impulse buys in the supermarket and the products are displayed in an atmosphere more akin to a chemist's than an off-licence. The Swedish model is based on the idea that by keeping control of price and availability, alcohol consumption is reduced.

A study carried out by international alcohol researchers in 2010 concluded that scrapping Sweden's state shops would lead to a 14% rise if sales were limited to private liquor stores. And allowing any grocery store to sell alcohol would result in a 29% rise in alcohol consumption.

However, such a proposal is unlikely to go down well with voters. Even Alcohol Concern warns of the dangers of "stockpiling".

And Dodd says it is absurd to crack down on supermarkets which would be most influenced by the change. "Supermarkets are already the most responsible alcohol outlets that there are and I can't see that preventing them from selling alcohol would improve things."

Discourage rounds

Buying rounds can create a social pressure to keep buying drinks because it's your turn. Last year the Sun reported that Prof Richard Thaler, an adviser to David Cameron on "nudge" - a form of behavioural economics, said buying rounds makes people drink more. He recommended that large groups set up a tab to be split at the end of an evening's drinking.

However bizarre, the idea of forbidding rounds is not new. During World War I, buying rounds - "treating" as it was known - was banned after fears that the war effort was being damaged by drunkenness.

Misell says it would be impractical to institute such a ban. But he supports the idea of improving public awareness on the perils of rounds. "My experience of rounds on a night out is that you very easily drink more than intended. My one piece of advice is - don't drink in rounds."

Ban alcohol marketing

Critics of the drinks industry say that cut price deals and cheeky advertising makes people drink more than they otherwise would.

Research in 2008 by the Royal College of Physicians found a link between sports sponsorship by alcohol firms and binge drinking. At the time half of all Premier League football teams and all 12 of the Guinness Premier League rugby clubs had alcohol firms as a sponsor. Today, Everton has a brewer - Chang - as its shirt sponsor and, until recently, Liverpool shirts carried the name of Carlsberg.

Alcohol Concern wants to see alcohol advertising banned from sport, television, and in cinemas for films aimed at those under 18. In theory, advertising is forbidden from associating alcohol with social or sexual success.

Official advice on drinking

  • Introduced in 1987, updated in 1995
  • Men: 21 units a week max, with no more than three or four units a day
  • Women: 14 units a week max, with no more than two or three units a day
  • After heavy drinking, no alcohol for 48 hours to allow body to recover

"But in practice few ads don't include those two things," says Misell. By way of example he points to the beer advert featuring Holly Valance flirting with two Australian comedians. He is also in favour of renaming the large glass of wine (250ml) extra large - it equals a third of a bottle of wine. The small (175ml) glass could then be renamed medium, with a new small size(125ml) available.

Alcohol promotions such as three bottles of wine for £10, or trays of beer tied into the World Cup, are still common in England. However they've been banned in Scotland. Financial Times wine critic Jancis Robinson says banning such deals makes sense. "Cut price wine deals are killing wine suppliers, too."

But Sarah Hanratty, a spokeswoman for the Portman Group, which represents the drinks industry, says banning sports sponsorship and other forms of marketing would punish the sensible majority. "It's a competitive market and the role of marketing is to help consumers choose between brands based on their lifestyle."

Target middle-class professionals

Much of the media attention to do with binge drinking is focused on public drunkenness. But it's arguable that the greater problem is the health impact of drinking too much.

Liver disease is the only major cause of death in Britain that is on the increase. Hospital admissions for alcoholic liver disease among people in their early 30s in north-east England have increased by more than 400% in the past eight years.

Tony Blair on his drinking habits in office

Alastair Campbell, Tony Blair's former spokesman, has recently pointed out that middle-class professionals are now the most frequent drinkers in the country. According to the Office for National Statistics 41% of professional men drink more than their daily limit at least once a week. But instead of targeting the Rioja-drinking classes, the focus of much rhetoric was on the damage done by public drunkenness. For many commentators, the government is pointing at the wrong group.

Nicholas Lezard wrote in the Guardian that Cameron is "trying to make us think of the proletariat getting smashed on cut-price lager". Rod Liddle in the Sunday Times agrees. "He [Cameron] doesn't mean someone who has spent the evening with a really nice Sancerre". He means the poor but "the poor, do not, on the whole, binge drink".

But is it really feasible to target the middle-class professional with their trusty gin and tonic or bottle of pinot noir? Jancis Robinson says it's all unworkable. "I really can't see how the government can effectively control what we drink in our own homes."

Not in front of the children

Child joining in a family toast When - and how - to introduce a child to alcohol?

Parents who drink a lot in front of their children may normalise the idea of heavy drinking. The Demos report, Under the Influence, argued that the government should consider issuing advice to parents about drinking in front of their children.

"This evidence, although limited, fits with what we know about behaviour - that steady exposure to norms and habits tacitly builds attitudes. Therefore more consideration needs to be given to advice that is given to parents about drinking in front of children."

Carrie Longton, co-founder of Mumsnet, says parents need to be aware how they're seen by the children. "You need to teach by example. What you drink is important." So careful about drinking that second glass of wine in front of the children.

Frank Furedi, author of Paranoid Parenting, agrees that parents have an important role to play. But far from avoiding alcohol in front of the kids, parents should allow teenagers to drink a little with a meal.

It removes the mystique of "an illegal drug" and makes it part of food culture, he argues. His view goes against official advice. In 2009, Sir Liam Donaldson, England's chief medical officer at the time, said that children aged under 15 should never drink alcohol.

Stop exaggerating the problem

Traditional social lubricant

The British believe alcohol is a disinhibitor, that it makes people amorous or aggressive.

But it is possible to change our drinking culture. Cultural shifts happen all the time, and there is extensive evidence to show it doesn't take much to effect dramatic changes in how people behave when they drink.

These show that even when people are very drunk, if they are given an incentive - either financial reward or social approval - they are perfectly capable of remaining in complete control of their behaviour.

Figures from 2006 show that the UK was not even among the top 10 per capita alcohol consumers in Europe. And alcohol consumption has been falling here for the past decade. Beer consumption has been declining for decades. And last year for the first time, wine sales fell. Even the worry about youth drinking may be overdone. 2010 NHS statistics showed that 55% of 11 to 15-year-olds have never drunk alcohol, an increase on previous years. Longton says these figures should give parents the confidence to be firm: "My children will say 'mummy everyone's doing it' but the statistics don't bear that out."

Bartlett says that exaggerating the problem can have negative effects. It leads to false "social norming" - people thinking that everyone else is binge drinking so why shouldn't they. "One reason university students go on a bender is because they overestimate the amount all their peers are drinking." But publishing the facts can challenge this. Some student unions have begun putting up posters giving the real drinking statistics for students, which are on average often far lower than expected. Once the true figure is displayed, students tailor their drinking accordingly. In other words, it doesn't do any good to hype up the problem.

Misell accepts that the UK is by no means at the top of the drinking league. But he argues that people are still drinking too much. "There's a big gap between the perception and reality of light drinking. For many it's three or four pints. But the advice from the Chief Medical officer is 3-4 units a day for a man and 2-3 for a woman. In some cases two pints would put you over the recommended limit."

Neo-Nazi murders: Germany holds minute's silence

Neo-Nazi murders: Germany holds minute's silence

Candles are lit during a commemoration for victims of neo-Nazi violence in Berlin (23 Feb 2012)

German Chancellor Angela Merkel has described 10 neo-Nazi murders as a "disgrace for our country" and appealed to victims' families for forgiveness.

Nine men, most of them of Turkish origin, and a policewoman have died since 2000 but the neo-Nazi gang blamed for their deaths emerged only recently.

A ceremony took place in Berlin and a minute's silence was held across the country to remember the victims.

Mrs Merkel told victims' families at the ceremony that "we mourn with you".

She promised to do everything possible to prevent a repeat of the "cold-blooded" murders.

Before she spoke, candles were lit in memory of those killed by a gang based in the eastern city of Zwickau that called itself the National Socialist Underground (NSU).

Ten burning candles, ten lives snuffed out”

Angela Merkel German Chancellor

Speaking in Berlin's concert hall, the chancellor named all the victims and gave details of their lives. "Ten burning candles, ten lives snuffed out," she said.

Shortly after the ceremony, at noon, a minute's silence was observed throughout Germany. Trains and buses came to a standstill and employers and unions urged people to halt their work.

The NSU had been undetected for years, prompting criticism of police and intelligence services.

Its existence was revealed last November when two suspected founders were found dead in a caravan and another, Beate Zschaepe, blew up her rented flat in Zwickau and gave herself up to police.

The chancellor apologised to the families for the fact that suspicion for the race murders had fallen, in some cases, on the victims' relatives themselves.

The ceremony was also addressed by Semiya Simsek and Gamze Kubasik, daughters of two of the victims.

Ms Simsek's father, a florist, was fatally shot in September 2000. "Not once in 11 years were we allowed to be treated as genuine victims," she said.

Gamze Kubasik, whose father was shot at his Dortmund kiosk in April 2006, expressed her hope of a future marked by greater "togetherness".

The former president, Christian Wulff, had been due to address the ceremony but he was replaced by Mrs Merkel because of his resignation last week.

Barack Obama apology to Afghanistan over Koran burning

Barack Obama apology to Afghanistan over Koran burning

Afghan police and plain-clothed security officials fire shots into a crowd of about 500 protesters in Kabul

President Barack Obama has apologised to the Afghan people for the burning of Korans by American troops at a US base.

In a letter to President Hamid Karzai, Mr Obama expressed his "deep regret" and said the incident earlier this week was a genuine mistake.

Demonstrations against the desecration have continued for a third day across northern and eastern Afghanistan.

Two foreign soldiers, believed to be Americans, have been killed, along with at least six Afghan people.

On Wednesday, another seven people were killed and dozens injured in protests.

Mr Obama's letter, delivered by the US ambassador to Afghanistan, assured the Afghan president that US authorities would question all those responsible.

At the scene

It started at about 09:00 when people from different villages around Baghlan converged on the town centre. About 1,000 demonstrators gathered in front of the police station and there was a lot of anger and violence. Then suddenly we heard an outbreak of machine-gun fire.

We went to the hospital where the injured were taken and a wounded policeman there told us that demonstrators shot at police. Officials say they are conducting an investigation to find out who opened fire.

After the violence, people escaped from the area, shops were closed and eventually demonstrators left. But it was an intense episode. People were shouting anti-American slogans expressing their outrage at the burning of the Koran. They also accused the Americans of being opposed to their religion.

"I convey my deep sympathies and ask you and the people to accept my deep apologies," the letter said.

President Karzai told members of the Afghan parliament that a US officer was responsible for the burning.

But he said it was done out of "ignorance".

In addition to those killed, many people have been injured in the protests, some of them critically, while armed men on Thursday also attacked at least two military installations.

Crowds shouting "death to Obama" have been throwing stones and setting fire to the US flag.

Meanwhile the Taliban has called on Afghans to kill and beat all invading forces in revenge for "insulting" the Koran.

In a statement a Taliban spokesman said Afghans should "not stop at protesting" but instead target military bases and personnel to "teach them a lesson that they will never again dare to insult the Holy Koran".

'Death to America'

The BBC's Andrew North, in the Afghan capital, says many officials sympathise with the outrage the US has provoked across the country.

He says Friday prayers may spark more tensions, depending on the tone set by religious leaders.

Protests map The protests have become more widespread

Police, local officials and tribal elders have told the BBC there have been major protests in at least nine areas across the country, each involving many hundreds of people.

The worst incident was in Khogyani in Nangarhar province, where a man wearing an Afghan army uniform killed two Nato soldiers who are believed to be from the US.

Two protesters were also killed and seven injured as Nato forces opened fire when armed men attacked the US/Afghan base.

Further south, in Uruzgan province, two people were killed and at least eight others wounded, three of them police, in clashes between protesters and Afghan security forces, local officials told the BBC's Bilal Sarwary.

They said demonstrators were carrying guns, metal bars and sticks.

Crowd of Afghans There have now been three days of protests over the burning of the Koran at a US military base

In northern Baghlan province, one civilian was killed and two others injured, while two police were also hurt.

Another person was killed in Laghman province east of Kabul, where local police said several hundred people were chanting "Death to America".

More than 3,000 people gathered in Mehtar Lam, the capital of Laghman province, with some burning an effigy of President Obama.

Police say fights broke out as they stopped hundreds of protesters entering the centre of Kabul.

And in Asadabad, some 1,500 demonstrators were said to be burning US flags and tyres and shouting anti-American slogans.

A French military base to the east of Kabul was attacked.

Muslims consider the Koran the literal word of God and treat each book with deep reverence.

Last year, at least 24 people died in protests across Afghanistan after a hardline US pastor burned a Koran in Florida.

Syria unrest: Reporters' deaths spark Western outrage

Syria unrest: Reporters' deaths spark Western outrage

The killings of two Western reporters in the city of Homs and reported deaths of some 60 people across Syria have triggered further Western outrage towards the Damascus government.

Sunday Times reporter Marie Colvin, an American, and French photographer Remi Ochlik died in shelling by Syria's government forces.

The US said it was "another example of the shameless brutality" of the regime.

French President Nicolas Sarkozy said: "That's enough... The regime must go."

Syrian troops have been shelling opposition-held areas of Homs for weeks.

Thousands have died since the unrest erupted last March.

The International Red Cross said it hoped Wednesday's deaths would draw the attention of the world to the many hundreds of other people suffering in Syria.

It earlier urged the government and rebels to agree to a daily ceasefire, to allow medical supplies to reach the worst affected areas and get civilians out.

However, there is no sign yet of this being agreed.

'Dreadful events'

Colvin, 56, and Ochlik, 28, were reportedly staying in a house in Homs' area of Baba Amr that was being used by activists as a media centre when it was hit by a shell on Wednesday morning.

Analysis

Marie would not want any tribute to leave out mention of the people she met, the stories she heard. She often spoke of how humbled she was by the "quiet bravery of civilians".

We've come to expect that wherever something of consequence was happening, Marie would be there. Her signature was not just to go to a story, but to stay for as long as she could, regardless of the danger or discomfort.

She admired the pioneering journalism of fellow American Martha Gelhorn. I always saw her as the Martha of our generation: brave and beautiful. A woman with a wicked laugh, a sensitive soul, and a steely determination to tell the stories that mattered. She had both guts and glamour.

I remember a conversation long ago where she told me a partner wanted her to be what she called a "Laura Ashley" - pretty and perfect in the home. But that wasn't Marie and she knew it. She was, without exception, a kind and considerate colleague and fellow traveller, a woman who inspired and engaged.

Rockets were also said to have hit the building's garden when people tried to flee afterwards.

At least two other foreign journalists were wounded, activists said.

One was named as British freelance photographer Paul Conroy, who was working with Colvin, and Edith Bouvier of the French newspaper, Le Figaro. Bouvier was said to be in a serious condition. The dead and the injured journalists are said to have been taken to a field clinic in Baba Amr.

Activists have expressed fears that Bouvier risks bleeding to death without urgent medical attention and they were trying to get her out.

Syrian state TV said the information ministry had asked officials in Homs to determine the location of foreign journalists because it had learned that some may have been injured.

In Washington, US State Department spokeswoman Victoria Nuland said: "This tragic incident is another example of the shameless brutality of the Assad regime."

Earlier, the US warned that it was not ruling out taking "additional measures" to assist the rebels if the government onslaught continued.

In Paris, French Foreign Minister Alain Juppe said his country held the Syrian government accountable for the deaths.

"Damascus owes us an answer," Mr Juppe said.

UK Prime Minister David Cameron told parliament: "This is a desperately sad reminder of the risks that journalists take to inform the world of what is happening, and the dreadful events in Syria."

Later, the Syrian ambassador to London was summoned to be told that the UK expected Damascus to arrange for the immediate repatriation of the journalists' bodies and to provide medical treatment for the injured British journalist.

Colvin's last article

The editor of the Sunday Times, John Witherow, said the newspaper was doing what it could to recover Colvin's body and get Conroy to safety.

"Marie was an extraordinary figure in the life of the Sunday Times, driven by a passion to cover wars in the belief that what she did mattered," he added. "She believed profoundly that reporting could curtail the excesses of brutal regimes and make the international community take notice."

Her mother told journalists Colvin's legacy was: "Be passionate and be involved in what you believe in. And do it as thoroughly and honestly and fearlessly as you can."

Ochlik had reported from Haiti and covered many of the recent uprisings in the Arab world.

Sunday Times Editor John Witherow: "She may have been targeted"

Colvin had been a foreign correspondent for the Sunday Times for two decades, and had reported from several war zones. She lost the sight in one eye in Sri Lanka in 2001 after being hit by shrapnel.

On Tuesday, she told the BBC the bombardment of Baba Amr by Syrian government artillery and tanks had been "unrelenting".

"I watched a little baby die today, absolutely horrific, a two year old - found the shrapnel had gone into the left chest and the doctor said: 'I can't do anything,' and his little tummy just kept heaving until he died. That is happening over and over and over.

The Sunday Times on Wednesday made available Colvin's last article in which she said, "We live in fear of a massacre".

Map of Homs

Western journalists have mostly been barred from Syria since the uprising began.

But increasingly, they have risked entering the country undercover, helped by networks of activists, to report from flashpoints.

Last month, the French television journalist, Gilles Jacquier, was killed in Homs while visiting the city on a government-organised trip.

Anthony Shadid, of the New York Times, died of an apparent asthma attack in Syria last week.
