Graphene lights up with new possibilities
— 29 Nov 2011 | ChemistryThe future brightened for organic chemistry when researchers at Rice University found a highly controllable way to attach organic molecules to pristine graphene, making the miracle material suitable for a range of new applications…
Grey matter in brain's control centre linked to ability to process reward
— 29 Nov 2011 | HealthThe more grey matter you have in the decision-making, thought-processing part of your brain, the better your ability to evaluate rewards and consequences. That may seem like an obvious conclusion, but a new study conducted at the U.S. Department of Energy's Brookhaven National Laboratory is the first to show this link between structure and function in healthy people - and the impairment of both structure and function in people addicted to cocaine. The study appears in the Journal of Cognitive Neuroscience…
Genetic code of first arachnid cracked
— 28 Nov 2011 | BiologyAn international team of scientists - including Ghent VIB scientists - has succeeded in deciphering the genome of the spider mite. This is also the first known genome of an arachnid. This premiere not only brings along new insights into the evolution of arthropods, but also offers new opportunities to develop means of crop protection against the spider mite…
How bats 'hear' objects in their path
— 28 Nov 2011 | BiologyBy placing real and virtual objects in the flight paths of bats, scientists at the Universities of Bristol and Munich have shed new light on how echolocation works. Their research is published today in Behavioural Processes…
Researchers use CT to recreate Stradivarius violin
— 28 Nov 2011 | TechnologyUsing computed tomography (CT) imaging and advanced manufacturing techniques, a team of experts has created a reproduction of a 1704 Stradivarius violin. Three-dimensional images of the valuable violin and details on how the replica was made were presented today at the annual meeting of the Radiological Society of North America (RSNA)…
Counting cats: The endangered snow leopards of the Himalayas
— 28 Nov 2011 | BiologyThe elusive snow leopard (Panthera uncia) lives high in the mountains across Central Asia. Despite potentially living across 12 countries the actual numbers of this beautiful large cat are largely unknown. It is thought that there might be somewhere between 350 and 500 distributed across Nepal's northern frontier. New research published in BioMed Central's open access journal BMC Research Notes has used genetic analysis to show that the numbers of snow leopards in the central Himalayas is actually much lower than suggested…
Climate sensitivity to CO2 more limited than extreme projections
— 25 Nov 2011 | EnvironmentA new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies - and, in fact, may be less severe than projected by the Intergovernmental Panel on Climate Change report in 2007…
Ancient environment found to drive marine biodiversity
— 25 Nov 2011 | Geology and palaeontologyMuch of our knowledge about past life has come from the fossil record - but how accurately does that reflect the true history and drivers of biodiversity on Earth?…
Surprise role of nuclear structure protein in development
— 25 Nov 2011 | BiologyScientists have long held theories about the importance of proteins called B-type lamins in the process of embryonic stem cells replicating and differentiating into different varieties of cells. New research from a team led by Carnegie's Yixian Zheng indicates that, counter to expectations, these B-type lamins are not necessary for stem cells to renew and develop, but are necessary for proper organ development. Their work is published 24 November by Science Express…
Metabolic defects in mice corrected with transplanted embryonic neurones
— 25 Nov 2011 | HealthA new study has revealed that immature neurones taken from healthy mouse embryos can repair damaged brain circuitry and partially normalise metabolism when transplanted into adult mice that have grown morbidly obese due to a genetic deficiency. This proof-of-principle discovery represents one step down a long road toward neuronal replacement therapy, which researchers hope might one day be used to repair brains that have been injured by trauma or disease…
