Researchers may have discovered key to life before its origin on Earth
— 29 Feb 2008 | BiologyAn important discovery has been made with respect to the mystery of 'handedness' in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry 'handedness' in a larger number than previously thought…
Magnetic atoms of gold, silver and copper have been obtained
— 29 Feb 2008 | PhysicsAn international team led by Physics and Chemistry teams from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) - become magnetic…
Researchers solve decade-old mystery
— 28 Feb 2008 | ChemistryEnvironmentally friendly hydrogen gas fuelled vehicles can dramatically reduce greenhouse gas emissions and lessen the country's dependence on sources of fossil fuel. Though several hydrogen vehicles exist on the market today, there is still much room for improvement in the way that hydrogen is stored on-board the vehicle…
Why juniper trees can live on less water
— 28 Feb 2008 | BiologyAn ability to avoid the plant equivalent of vapour lock and a favourable evolutionary history may explain the unusual drought resistance of junipers, some varieties of which are now spreading rapidly in water-starved regions of the western United States, a Duke University study has found…
Does Ginkgo biloba affect memory?
— 28 Feb 2008 | HealthTaking the supplement Ginkgo biloba had no clear-cut benefit on the risk of developing memory problems, according to a study published in the 27 February 2008, online issue of Neurology(R), the medical journal of the American Academy of Neurology…
Detecting bone erosion in arthritic wrists
— 28 Feb 2008 | HealthBoth magnetic resonance imaging (MRI) and computed tomography (CT) are more sensitive than radiography - the standard imaging technique - for detecting bone erosions in rheumatoid arthritis (RA), according to research published in the open access journal Arthritis Research and Therapy…
Destruction of Sumatra forests driving global climate change and species extinction
— 28 Feb 2008 | EnvironmentTurning just one Sumatran province's forests and peat swamps into pulpwood and palm oil plantations is generating more annual greenhouse gas emissions than the Netherlands and rapidly driving the province's elephants into extinction, a new study by WWF and partners has found…
Chewing gum - the new post-operative medicine
— 28 Feb 2008 | HealthIn an article recently recommended by Bradley Kropp of Faculty of 1000 Medicine, researchers find chewing gum is a simple solution to the recovery of bowel function after gastrointestinal surgery - a problem that has troubled patients and physicians for decades…
This is your brain on jazz: researchers use MRI to study spontaneity, creativity
— 28 Feb 2008 | HealthA pair of Johns Hopkins and government scientists have discovered that when jazz musicians improvise, their brains turn off areas linked to self-censoring and inhibition, and turn on those that let self-expression flow…
Capturing sunlight
— 28 Feb 2008 | PhysicsSolar cell technology is marching ahead, though it still struggles with the two problems: efficiency and high production costs. In collaboration with Satoshi Uchida at the University of Tokyo, Michael Graetzel and his research group at the Swiss Federal Institute of Technology in Lausanne have now developed new sensitisers that should help an inexpensive type of solar cell to be more efficient…
