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.

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

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.

I was at the outer limit - stiff whisky or G&T before dinner, couple of glasses of wine or even half a bottle with it”

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."

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.

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

Marie Colvin and Remi Ochlik were killed in a makeshift media centre in Homs

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.

Sweden snow: Man 'survives two months trapped in car'

Sweden snow: Man 'survives two months trapped in car'

Survival expert Dale Collett explains how, in theory, somebody could survive for two months with hardly any food or water

A Swedish man has survived being trapped in his snow-covered car for two months without food, police say.

The car was found on Friday at the end of a forest track more than 1 km (0.6 miles) from a main road in northern Sweden.

Police say the temperature in the area had recently dropped to -30C (-22F).

The man, who was too weak to utter more than a few words, said he had been inside since 19 December. He may have survived by drinking melted snow.

Police say they have no reason to doubt his story.

Sleeping bag

The man, who has not been named, is recovering at Umea University Hospital - where staff say he is doing well considering the circumstances.

The 45-year-old was discovered by snowmobilers who initially assumed the car was a wreck until they dug their way to a window and saw movement inside, reported the Vasterbotten Courier newspaper.

The man was huddled in a sleeping bag on the back seat, said policeman Ebbe Nyberg.

"He was in a very poor state. Poor condition. He said he'd been there for a long time and had survived on a little snow.

"He said himself he hadn't eaten anything since December," Mr Nyberg said.

Doctors at the Umea University Hospital said they would normally expect a person to survive without food for around four weeks, said the Vasterbotten Courier.

One doctor told the newspaper that the man might have survived so long by going into a kind of hibernation.

Male Y chromosome extinction theory challenged

Male Y chromosome extinction theory challenged

Human cells carry 23 pairs of chromosomes
Human cells carry 23 pairs of chromosomes, including one pair which determine gender

Men may not become extinct after all, according to a new study.

Previous research has suggested the Y sex chromosome, which only men carry, is decaying genetically so fast that it will be extinct in five million years' time.

A gene within the chromosome is the switch which leads to testes development and the secretion of male hormones.

But a new US study in Nature suggests the genetic decay has all but ended.

Professor Jennifer Graves of Australian National University has previously suggested the Y chromosome may become extinct in as little as five million years' time, based on the rate at which genes are disappearing from the chromosome.

Genetics professor Brian Sykes predicted the demise of the Y chromosome, and of men, in as little as 100,000 years in his 2003 book Adam's Curse: A Future without Men.

The predictions were based on comparisons between the human X and Y sex chromosomes. While these chromosomes were once thought to be identical far back in the early history of mammals, the Y chromosome now has about 78 genes, compared with about 800 in the X chromosome.

The Y is not going anywhere and gene loss has probably come to a halt”

Dr Jennifer Hughes Whitehead Institute, Cambridge, Massachusetts

Jennifer Hughes and colleagues at the Whitehead Institute in Cambridge, Massachusetts, have sought to determine whether rumours of the Y chromosome's demise have been exaggerated.

In a previous Nature paper in 2005, they compared the human Y chromosome with that of the chimpanzee, whose lineage diverged from that of humans about six million years ago.

They have now sequenced the Y chromosome of the rhesus monkey, which is separated from humans by 25 million years of evolution.

The conclusion from these comparative studies is that genetic decay has in recent history been minimal, with the human chromosome having lost no further genes in the last six million years, and only one in the last 25 million years.

"The Y is not going anywhere and gene loss has probably come to a halt," Ms Hughes told BBC News. "We can't rule out the possibility it could happen another time, but the genes which are left on the Y are here to stay.

"They apparently serve some critical function which we don't know much about yet, but the genes are being preserved pretty well by natural selection."

X-Y crossing

Most humans cells contain 23 sets of chromosomes, including one pair of sex chromosomes. In women, this sex pair consist of two X chromosomes, while men have one X and one Y chromosome. It is a gene within the Y chromosome which triggers the development in the embryo of male testes and the secretion of male hormones.

Professor Julian Parkhill visits the Wellcome Collection to unravel the science behind the genome

Genetic deterioration of the Y chromosome has occurred because unlike with the two X chromosomes in women, there is very little swapping of genetic material between the Y and X chromosome during reproduction. This means mutations and deletions in the Y chromosome are preserved between (male) generations.

"The X is fine because in females it gets to recombine with the other X but the Y never gets to recombine over almost its entire length, and shutting down that recombination has left the Y vulnerable to all these degenerative forces," said Dr Hughes, "which is why we're left with the Y we have today."

Commenting on the paper, Professor Mark Pagel, an evolutionary biologist at the University of Reading and author of Wired for Culture: Origins of the Human Social Mind, said that while there might be some squabbling in academic circles over the timings of the events, the paper told us there was a future for males in the very long term.

"It's a very nice piece of work, showing that gene loss in the male-specific region of the Y chromosome proceeds rapidly at first - exponentially in fact - but then reaches a point at which purifying selection brings this process to a halt."

US cities built in the 20th Century have long catered for a population that prefers to take the car to shop, dine and work. But an ageing population and a young professional workforce looking for an urban lifestyle have forced city planners to reconsider the existing road and pavement infrastructure.

But how do you remake a city into a pedestrian dream, and how do you re-educate the public about its transportation choices?

The BBC's Franz Strasser went to Raleigh, North Carolina, where an unsanctioned street sign campaign called Walk Raleigh caught the attention of city officials and pedestrians alike.

New York police 'spied on' New Jersey Muslims

NYPD Police Commissioner  Ray Kelly speaks at a press conference 3 February 2012

New York City police secretly collected information on Muslim communities in nearby Newark, New Jersey, police records have shown.

Newark Mayor Cory Booker said he was not informed of the surveillance, revealed by the Associated Press.

"This raises a number of concerns," Mr Booker said, promising to investigate. "It's just very, very sobering."

Earlier this week university officials in the US north-east protested against NYPD monitoring of Muslim students.

Administrators at Yale and Columbia protested about the police department's activities, which the NYPD said were justified in an effort to identify possible campus radicalisation.

Earlier this month, civic groups from around the US called for a legal investigation into intelligence-gathering on Shia Muslims in New York.

NYPD's demographic unit compiled information on mosques and Muslim-owned businesses in Newark in 2007, AP reported.

The secret police report obtained by the news agency mentions no evidence of terrorism or criminal behaviour.

"These locations provide the maximum ability to assess the general opinions and general activity of these communities," the report said.

Similar reports were prepared for two counties in Long Island, in New York state.

Jersey unsure

In a statement, the NYPD told the BBC that they had informed Newark officials of their operations.

Newark's former police director, Garry McCarthy, told the Associated Press that the NYPD had contacted his police department "as a courtesy" before sending the officers.

The police department goes where there are allegations. Remind yourself when you turn out the light tonight”

No Newark police officers were involved in the surveillance, according to Mr McCarthy.

But New Jersey Governor Chris Christie said he had knowledge of the operation, which he called "disturbing".

Newark Mayor Cory Booker said the extent of the reported surveillance came as a surprise to him.

"If anyone in my police department had known this was a blanket investigation of individuals based on nothing but their religion, that strikes at the core of our beliefs and my beliefs very personally, and it would have merited a far sterner response,'' he said.

"We're going to get to the bottom of this."

The report notes Newark's large Portuguese and Brazilian communities, but says that only information about "Islamic religious centers" and Muslim-owned businesses were gathered.

However, polls show that most New Yorkers strongly support the NYPD's counter-terrorism efforts.

On Tuesday, New York City Mayor Michael Bloomberg strongly defended the city's police department after university leaders protested over campus monitoring.

"The police department goes where there are allegations," Mr Bloomberg said.

"And they look to see whether those allegations are true. That's what you'd expect them to do. That's what you'd want them to do. Remind yourself when you turn out the light tonight."

Is English or Mandarin the language of the future?

Is English or Mandarin the language of the future?

Mandarin-English dictionary

English has been the dominant global language for a century, but is it the language of the future? If Mandarin Chinese is to challenge English globally, then it first has to conquer its own backyard, South East Asia.

In Malaysia's southernmost city of Johor Bahru, the desire to speak good English has driven some children to make a remarkable two-hour journey to school every day.

Nine-year-old Aw Yee Han hops on a yellow mini van at 04:30. His passport is tucked inside a small pouch hung around his neck.

This makes it easier for him to show it to immigration officials when he reaches the Malaysian border.

His school is located on the other side, in Singapore, where unlike in Malaysia, English is the main language.

It's not your typical school run, but his mother, Shirley Chua thinks it's worth it.

"Science and maths are all written in English so it's essential for my son to be fluent in the language," she says.

The assumption that Mandarin will grow with China's economic rise may be flawed. Consider Japan which, after spectacular post-war economic growth, became the world's second-biggest economy. The Japanese language saw no comparable rise in power and prestige.

The same may prove true of Mandarin. The character-based writing system requires years of hard work for even native speakers to learn, and poses a formidable obstacle to foreigners. In Asia, where China's influence is thousands of years old, this may pose less of a problem. But in the West, even dedicated students labour for years before they can confidently read a text of normal difficulty on a random topic.

Finally, many languages in Asia, Africa and the Amazon use "tones" (rising, falling, flat or dipping pitch contours) to distinguish different words. For speakers of tonal languages (like Vietnamese) learning the tones of Mandarin poses no particular difficulty. But speakers of non-tonal languages struggle to learn tones in adulthood - just ask any adult Mandarin-learner for their funniest story about using a word with the wrong tone.

An estimated 15,000 students from southern Johor state make the same bus journey across the border every day. It may seem like a drastic measure, but some parents don't trust the education system in Malaysia - they worry that the value of English is declining in the country.

Since independence from the British in 1957, the country has phased out schools that teach in English. By the early 1980s, most students were learning in the national language of Malay.

As a result, analysts say Malaysian graduates became less employable in the IT sector.

"We've seen a drastic reduction in the standard of English in our country, not just among the students but I think among the teachers as well," says political commentator Ong Kian Ming.

Those who believe that English is important for their children's future either send their kids to expensive private schools or to Singapore, where the government has been credited as being far-sighted for adopting the language of its former colonial master.

Nearly three-quarters of the population in Singapore are ethnic Chinese but English is the national language.

Many believe that this has helped the city state earn the title of being the easiest place to do business, by the World Bank.

However, the dominance of English is now being challenged by the rise of China in Singapore.

The Singapore Chinese Chamber Institute of Business has added Chinese classes for business use in recent years.

Students are being taught in Mandarin rather than the Hokkien dialect spoken by the older Chinese immigrants.

These courses have proved popular, ever since the government began providing subsidies for Singaporeans to learn Chinese in 2009 during the global financial crisis.

"The government pushed to provide them with an opportunity to upgrade themselves so as to prepare themselves for the economic upturn," says chamber spokesperson Alwyn Chia.

Some businesses are already desperate for Chinese speakers.

Lee Han Shih, who runs a multimedia company, says English is becoming less important to him financially because he is taking western clients to do business in China.

"So obviously you need to learn English but you also need to know Chinese," says Mr Lee.

As China's economic power grows, Mr Lee believes that Mandarin will overtake English. In fact, he has already been seeing hints of this.

"The decline of the English language probably follows the decline of the US dollar.

"If the renminbi is becoming the next reserve currency then you have to learn Chinese."

More and more, he says, places like Brazil and China are doing business in the renminbi, not the US dollar, so there is less of a need to use English.

Bilingualism

Indeed, China's clout is growing in South East Asia, becoming the region's top trading partner.

But to say that Mandarin will rival English is a "bit of a stretch", says Manoj Vohra, Asia director at the Economist Intelligence Unit.

Even companies in China, who prefer to operate in Chinese, are looking for managers who speak both Mandarin and English if they want to expand abroad, he says.

"They tend to act as their bridges."

So the future of English is not a question of whether it will be overtaken by Mandarin, but whether it will co-exist with Chinese, says Vohra.

He believes bilingualism will triumph in South East Asia.

It is a sound economic argument, but in Vietnam's case, there is resistance to learning Mandarin.

The country may share a border with China, but the Vietnamese government's choice to not emphasise Mandarin is an emotional one, says leading economist Le Dang Doanh.

Aw Yee Han and his mother Shirley Chua fears her son's English will suffer in the Malaysian school system

"All the streets in Vietnam are named according to generals and emperors that have been fighting against the Chinese invasion for 2000 years," he says.

Tensions flared up again last May over the disputed waters of the South China Sea.

Anti-Chinese sentiment means that young Vietnamese are choosing to embrace English - the language of a defeated enemy. Many families still bear the psychological scars from the Vietnam War with the United States.

Yet there is no animosity towards English because the founding father of Vietnam, Ho Chi Minh, made a clear distinction between the so-called American imperialists who were bombarding Vietnam and the American people, says Le Dang Doanh.

Many Vietnamese who have lost family members during the war are now studying in America, he says.

"We never forget any victim in the past but in order to industrialise and normalise a country, Vietnam needs to speak English."

The Vietnamese government has an ambitious goal to ensure all young people leaving school by 2020 will have a good grasp of the English language.

But it's not hard for young Vietnamese to accept English. For some, the language offers a sense of freedom in Vietnam, where the one-party communist state retains a tight grip on all media.

In a public square in central Hanoi, a group of young men are break-dancing to the pulsing beats of western hip hop. Ngoc Tu, 20, says he only listens to English music.

"The Ministry of Culture has banned a lot of [Vietnamese] songs and any cultural publications that refer to freedom or rebellion but... English songs are not censored."

It is debatable whether English or Mandarin will dominate in South East Asia in the future. There are arguments for both on the economic front.

But culturally, there is no dispute.

Even Mandarin language enthusiasts like Singaporean businessman Mr Lee, says that English will remain popular so long as Hollywood exists.

The success of movies such as Kung Fu Panda, an American production about a Chinese animal, has caused a lot of anxiety in China, he says.

There have been many cartoons in China about pandas before, but none had reached commercial success, says Mr Lee.

"The moment Kung Fu Panda hit the cinemas everybody watched it. They bought the merchandise and they learned English."

Barack Obama seeks to change US corporate tax code

Barack Obama seeks to change US corporate tax code

Barack Obama addresses the audience at the White House, Washington, DC 21 February 2012.
The US president has seen recent success on extending the payroll tax cut

Related Stories

US President Barack Obama is proposing cutting the US corporate tax rate from 35% to 28%, and closing loopholes, as part of a larger push for tax reform.

Announcing the plan, the US treasury secretary called the tax code loopholes "fundamentally unfair".

Republicans also propose lowering rates, but Mr Obama's plan is thought to have few chances of becoming law.

Correspondents say the president is using the plan to spark a debate on tax reform in an election year.

The plan does not include any overhaul of the individual tax code.

"Our current corporate tax system is outdated, unfair, and inefficient," Mr Obama said in a statement.

"It is unnecessarily complicated and forces America's small businesses to spend countless hours and dollars filing their taxes."

Treasury Secretary Timothy Geithner also called the current system inefficient, describing it as bad for job-creation.

He said the White House and Treasury plan would make the tax system more globally competitive and eliminate "fundamentally unfair" loopholes.

"We want to restore a system in which American businesses succeed or fail based on the products they make and the services they provide, not on the creativity of their tax engineers or the lobbyists they hire."

Loophole tax rate

The US currently has one of the top corporate tax rates in the world, but loopholes and other subsidies mean many companies pay a much lower effective tax rate.

According to the Congressional Budget Office, total corporate federal taxes represented 12.1% of US profits in 2011.

US media analysis

Washington Post's Wonkbook argues the plan is a challenge to businesses who have called for reform: "In a sense, their document is as much about showing how hard corporate tax reform will be as it is about getting corporate tax reform done."

Fox Business's Elizabeth MacDonald says that under the White House's plan, business such as utilities and car manufacturers would benefit, while the internet and biotech sectors could see higher taxes.

Writing in the National Review, Douglas Holtz-Eakin says: "Credit where credit is due," but adds that the rate is not competitive enough and that a minimum tax on foreign profits puts the US "out of step" with other developed countries.

Republican Representative Dave Camp and presidential hopeful Mitt Romney have proposed a 25% rate, while other Republican candidates have suggested rates as low as 12.5%.

While both parties have expressed interest in removing tax loopholes, there is disagreement on which subsidies will be need to be cut in order to make up for revenues lost through lowering the standard rate.

Removing the tax loopholes would be likely to raise tax revenues overall, with some companies paying more or less under the current system.

As part of the proposed plan, Mr Obama has suggested lowering the tax rate to 25% for manufacturing businesses and continuing research and development-based tax credits.

While the announcement fleshes out promises made in Mr Obama's January State of the Union address, it leaves certain key details, like the percentage of a minimum tax on foreign profits, up to Congress.

Correspondents say that the tax proposal - and the deliberate lack of detail in some areas - is a move by Mr Obama to shift responsibility to Congress.

Republicans in the House of Representatives have routinely opposed Mr Obama's legislative plans since winning control of the chamber in the 2010 elections.

Lab-grown meat is first step to artificial hamburger

Lab-grown meat is first step to artificial hamburger

Lab grown meat
The first strips of muscle have been grown in a project to develop a new way to produce meat

Related Stories

Dutch scientists have used stem cells to create strips of muscle tissue with the aim of producing the first lab-grown hamburger later this year.

The aim of the research is to develop a more efficient way of producing meat than rearing animals.

At a major science meeting in Canada, Prof Mark Post said synthetic meat could reduce the environmental footprint of meat by up to 60%.

"We would gain a tremendous amount in terms of resources," he said.

Professor Post's group at Maastricht University in the Netherlands has grown small pieces of muscle about 2cm long, 1cm wide and about a mm thick.

They are off-white and resemble strips of calamari in appearance. These strips will be mixed with blood and artificially grown fat to produce a hamburger by the autumn.

The cost of producing the hamburger will be £200,000 but Professor Post says that once the principle has been demonstrated, production techniques will be improved and costs will come down.

At a news conference, Prof Post said he was even planning to ask celebrity chef Heston Blumenthal to cook it.

In the beginning it will taste bland. I think we will need to work on the flavour”

"The reason we are doing this is not to show a viable product but to show that in reality we can do this," he told BBC News.

"From then on, we need to spend a whole lot of work and money to make the process efficient and then cost effective."

So why use such high tech methods to produce meat when livestock production methods have done the job effectively for thousands of years?

It is because most food scientists believe that current methods of food production are unsustainable.

Some estimate that food production will have to double within the next 50 years to meet the requirements of a growing population. During this period, climate change, water shortages and greater urbanisation will make it more difficult to produce food.

Prof Sean Smukler from the University of British Columbia said keeping pace with demand for meat from Asia and Africa will be particularly hard as demand from these regions will shoot up as living standards rise. He thinks that lab grown meat could be a good solution.

Butcher Demand for meat will increase at a time when it will be harder than ever for farmers to boost production

"It will help reduce land pressures," he told BBC News. "Anything that stops more wild land being converted to agricultural land is a good thing. We're already reaching a critical point in availability of arable land," he said.

Lab-grown meat could eventually become more efficient than producing meat the old fashioned way, according to Prof Post. Currently, 100g of vegetable protein has to be fed to pigs or cows to produce 15g of animal protein, an efficiency of 15%. He believes that synthetic meat could be produced with an equivalent energy efficiency of 50%.

So what is the synthetic burger likely to taste like?

"In the beginning it will taste bland," says Prof Post. "I think we will need to work on the flavour separately by trying to figure out which components of the meat actually produce the taste and analyse what the composition of the strip is and whether we can change that."

Prof Post also said that if the technology took off, it would reduce the number of animals that were factory farmed and slaughtered.

The BBC's Pallab Ghosh reports from Duggie's Dogs hot dog restaurant in Downtown Vancouver

But David Steele, who is president of Earthsave Canada, said that the same benefits could be achieved if people ate less meat.

"While I do think that there are definite environmental and animal welfare advantages of this high-tech approach over factory farming, especially, it is pretty clear to me that plant-based alternatives... have substantial environmental and probably animal welfare advantages over synthetic meat," he said.

Dr Steele, who is also a molecular biologist, said he was also concerned that unhealthily high levels of antibiotics and antifungal chemicals would be needed to stop the synthetic meat from rotting.
