Ion-based electronic chip to control muscles: Entirely new circuit technology based on ions and molecules
ScienceDaily (May 29, 2012) Klas Tybrandt, doctoral student in organic electronics at Linkoping University, Sweden, has developed an integrated chemical chip. The results have just been published in the journal Nature Communications. The Organic Electronics research group at Linköping University previously developed ion transistors for transport of both positive and negative ions, as well as biomolecules
Gardeners told ‘wash off compost’
27 May 2012 Last updated at 20:40 ET By Eleanor Bradford BBC Scotland Health Correspondent Gardeners are being warned to wash their hands after using compost following a series of Legionella cases in Scotland over the past five years. One man has died and five others have become ill after contracting a rare strain called ‘Legionella longbeachae’, which appears to come from compost. The unusual strain is well known in Australia and New Zealand, where bags of compost carry warning labels.
Persistent sensory experience is good for aging brain
ScienceDaily (May 24, 2012) Despite a long-held scientific belief that much of the wiring of the brain is fixed by the time of adolescence, a new study shows that changes in sensory experience can cause massive rewiring of the brain, even as one ages. In addition, the study found that this rewiring involves fibers that supply the primary input to the cerebral cortex, the part of the brain that is responsible for sensory perception, motor control and cognition.

In addition, the study found that this rewiring involves fibers that supply the primary input to the cerebral cortex, the part of the brain that is responsible for sensory perception, motor control and cognition. These findings promise to open new avenues of research on brain remodeling and aging.
New approach to ‘spell checking’ gene sequences
ScienceDaily (May 21, 2012) A PhD student from CSIRO and the University of Queensland has found a better way to ‘spell check’ gene sequences and help biologists better understand the natural world. The student, Lauren Bragg, has contributed to the May issue of the journal Nature Methods highlighting her new approach and its software implementation called Acacia
Cheap dysentery drug ‘promising’
20 May 2012 Last updated at 14:26 ET By James Gallagher Health and science reporter, BBC News A cheap drug, which is already prescribed for arthritis, could fight amoebic dysentery, according to researchers in the US.
Prosthetic retina in development
17 May 2012 Last updated at 07:19 ET Scottish scientists are working on a device to restore sight in people with a specific form of blindness. Strathclyde University in Glasgow aims to create a prosthetic retina to tackle age related macular degeneration (AMD)
New clues on how ApoE4 affects Alzheimer’s risk
ScienceDaily (May 16, 2012) Common variants of the ApoE gene are strongly associated with the risk of developing late-onset Alzheimer’s disease, but the gene’s role in the disease has been unclear.
Stopping brain death breakthrough
6 May 2012 Last updated at 13:34 ET By James Gallagher Health and science reporter, BBC News The tantalising prospect of treating a range of brain diseases, such as Alzheimer’s and Parkinson’s, all with the same drug, has been raised by UK researchers. In a study, published in Nature 1 , they prevented brain cells dying in mice with prion disease. It is hoped the same method for preventing brain cell death could apply in other diseases
Research censorship ‘problematic’
2 May 2012 Last updated at 13:01 ET By Pallab Ghosh Science correspondent, BBC News The editor of the world-leading scientific journal Nature says current procedures to assess and censor medical research potentially of use to terrorists need to be improved. Dr Philip Campbell 1 made his remarks to BBC News following the publication of controversial research into the bird flu virus H5N1 2 . Two research papers have raised the concern of anti-terrorist agencies
