Scientists find flaw in Einstein’s theory
Scientists in Australia say that the speed of light, far from being the universal constant that allowed Einstein to predict that E=mc2, is in fact slowing down. The claim, if proven, would force a rethink of almost everything that cosmologists now believe about the way the universe works, opening a new era of theoretical physics. The Australian study, published in Nature , also opens up the possibility of travelling faster than light, and so the ability to go back in time.

Exam board sends A-level scripts to wrong address
Britain’s biggest exam board sent 140 unmarked A-level scripts to the wrong address only days before the deadline to have the papers returned. The Assessment and Qualifications Alliance sent the information technology scripts to the home of Marc Patterson in Pittington, Co Durham, rather than to the examiner designated to mark them. The latest blunder infuriated teacher’s leaders, who said the continuing errors highlighted the enormous pressure on the exam system and the lack of quality control.

How Betty the crow is bending the rules of animal behaviour
A team of Oxford University scientists says it has demonstrated for the first time, with Betty the New Caledonian crow, that an animal can understand cause and effect and make a tool for a specific task. Not even chimpanzees have shown this level of sophisticated problem solving. Professor Alex Kacelnik, an expert in behavioural ecology at Oxford, said he was surprised by the bird’s intelligence.

US study links autism to MMR
One of the scientists who believes there may be a connection between autism and the measles, mumps and rubella vaccine has published new research suggesting a link. Dr Vijendra Singh of Utah State University found that many children with the developmental disorder had an ‘inappropriate immune response’ to the measles component of the vaccine. His findings are reported in the Journal of Biomedical Science . But Peter Lachmann, emeritus professor of immunology at Cambridge University, said that the conclusions drawn by Singh and his team did not make for a direct link between MMR and autism. ‘His hypothesis does not show causality; he is drawing unjustifiable conclusions from the antibody data he has collected,’ Professor Lachmann said.

Economists expose myth of costly conservation
Communities are financially better off in the long term if they leave nature alone, according to a rare collaboration between economists and scientists that shows preserving the environment pays dividends. Andrew Balmford, a Cambridge University biologist and lead author of the study published in Science , said the scale of economic losses of land conversion had surprised the Anglo-American team of 19 researchers. ‘The economics are absolutely stark. We thought that the numbers would favour conservation, but not by this much.’

Archaeologists fight to save medieval vessel
A storm of protest is rising over the probable fate of a medieval ship found preserved in the muddy bank of the river Usk in Newport, South Wales. The next month could be more dangerous for the ship than the past 500 years. The local museum has neither the resources nor the space to excavate, preserve and display the ship and no other museum has expressed an interest it.

Methane-eating life form may halt global warming
Scientists have discovered an organism believed to be the world’s oldest life form that lives on methane and could be harnessed to help combat global warming. The organism lives at the bottom of the Black Sea, an area previously believed to be without life. Researchers from the Max Planck Society in Germany were surprised to find corals, made by microorganisms, processing methane and sulphates in what is the largest oxygen-free area of the planet.

Heavier babies become better at maths
The weight of babies at birth has been shown to have a direct bearing on their mathematical ability in later life. Research by scientists at the Institute of Child Health, in London, found that every extra kilogram equated to an average 4.7 per cent improvement in maths test scores. Females showed more improvement per kilogram – 5.2 per cent – than males, who scored 4.2 per cent.
