With a broken promise, the government has handed the NHS over to the market | Clive Peedell
Reassurances on clinicians and local people controlling how services are commissioned look likely to be overturnedThe NHS needs to be reformed to remain true to its founding principles; the question is how. International evidence suggests that increasing marketisation and privatisation of healthcare services leads to greater expenditure, greater variations in care, reduced access to services, and erosion of professional standards. On that basis, the reforms have been heading in the wrong direction for a long time, with all the major political parties supporting policies that increase the role of the private sector in the N...

Brain-to-brain interface transmits information from one rat to another | Mo Costandi
Electronically-linked brains could facilitate rehabilitation and revolutionize computingIn Star Trek, the Borg is a menacing race of cybernetically-enhanced beings who conquer other races and assimilate them. They do not act as individuals, but rather as an interconnected group that makes decisions collectively. Assimilation involves integrating other life forms into the Collective, using brain implants that connect them to the "hive mind," such that their biology and technology can help the Borg to become the perfect race. This is a popular concept that can be found elsewhere in science fiction, but scientists have now mo...

Neurons in the brain switch identity and re-route fibres | Mo Costandi
New findings could one day lead to gene therapies for stroke and spinal cord injuriesThese drawings by Santiago Ramón y Cajal show the cellular structure of three different areas of the human cerebral cortex. The cortex is the seat of higher mental functions such as language and decision-making, and contains dozens of distinct, specialised areas. As Cajal's drawings show, it has a characteristic layered structure, which differs somewhat from one area to the next, so that the layers vary in thickness according to the number of cells they contain. Cells throughout the cortex are arranged in a highly ordered manner. Those in...

Paralysed people could get movement back through thought-control
Brain implant could allow people to 'feel' the presence of infrared light and one day be used to move artificial limbsScientists have moved closer to allowing paralysed people to control artificial limbs with their thoughts following a breakthrough in technology that gave rats an extra sense.A brain implant that allows the animals to "feel" the presence of invisible infrared light could one day be used to provide paralysed people with feedback as they move artificial limbs with their thoughts, or it could even extend a person's normal range of senses.Miguel Nicolelis, a neurobiologist at Duke University in North Carolina w...

Families face battle with GSK over dangerous diabetes drug
Exclusive: Pharmaceutical giant resists claims despite settlement with victims in USThousands of families in the UK could be deprived of compensation for the death or harm of a relative caused by the diabetes drug Avandia, even though the British maker has agreed to pay billions of dollars to settle similar claims in the US.The licence for Avandia was revoked in Europe, in September 2010, because of evidence that it could cause heart failure and heart attacks. The drug can still be prescribed in the US, but not to patients at risk of heart problems.A scientist with the Food and Drug Administration estimated that Avandia co...

Lucy Mangan: wanted – mother for Neanderthal baby
'Don't you long, occasionally, for something really, really interesting, something different, something overwhelmingly "other" to happen?'It's possible that the snow has driven me stir crazy. Although, as someone who, when under stress, still draws diagrams of the underground, Womble burrow-based home that she plans to build when she wins the lottery, I think that is highly unlikely. In any case, I have been seized by the idea of having another baby.Not just any old baby – I've already got one of those – but a Neanderthal baby. Earlier this week Professor George Church, a genetic researcher at Harva...

Any defence of sugar is pure confection | Aseem Malhotra
More and more people are challenging the food industry's PR machine. The evidence shows that sugar, not fat, is the enemyThe public health minister, Anna Soubry, has commented that the poor are more likely to be obese. It is well known that social status is linked to health, but her comments were also motivated by a mentality that victimises the most vulnerable. She should really be directing her criticism at the food industry. There is no doubt that an oversupply of cheap junk food fuelled by unregulated and irresponsible marketing limits our ability to make healthy choices. But there is an equally important question that...

Ice age art at the British Museum was crafted by 'professional' artists
The best art by ice-age Homo sapiens are masterpieces that took hundreds of hours to produce, says curatorIt's smaller than your thumb: a little piece of mammoth ivory delicately carved into the shape of a woman's head. But this miniature sculpture, with one wonky eye and rather elongated, slightly Modigliani-esque proportions, is the oldest known portrait in the world, and is about to go on show to the public for the first time in Britain in a new exhibition at the British Museum, Ice Age Art: Arrival of the Modern Mind.Some 26,000 years ago, in a valley teeming with game in what is now Moravia, a man or woman carved this...

What will be the next great invention? Ask a teenager
From the lightbulb to the web, the British have a great history of innovation. We must help young people to keep inspiring usFrom the sewing machine to ice cream, the railway to the telegraph, the 19th century was awash with invention. It seems you couldn't turn your back without someone inventing the flushing toilet, the typewriter, the light bulb, X-ray, or the wireless.The Victorians certainly had a knack for recognising a need, an opportunity, a better way of doing things – as a recent poll of Britain's greatest inventions shows. And recognising needs is what innovation is all about. It's not about widgets for the sa...

Apophis: why Nasa takes a special interest in the asteroid's latest pass
Asteroid Apophis arrives this week for a close pass of Earth. This isn't the end of the world but a new beginning for research into potentially hazardous asteroidsApophis hit the headlines in December 2004. Six months after its discovery, astronomers had accrued enough images to calculate a reasonable orbit for the 300-metre chunk of space rock. What they saw was shocking. There was a roughly 1 in 300 chance of the asteroid hitting Earth during April 2029. Nasa issued a press release spurring astronomers around the world to take more observations in order to refine the orbit. Far from dropping, however, the chances of an i...
