NYU researchers identify new neurological deficit behind lazy eye
— 11:25 GMT | HealthResearchers at New York University's Centre for Neural Science have identified a new neurological deficit behind amblyopia, or 'lazy eye.' Their findings, which appear in the most recent issue of the Journal of Neuroscience, shed additional light on how amblyopia results from disrupted links between the brain and normal visual processing…
Sizing up stockpiles of children's vaccines
— 11:25 GMT | HealthA creative version of a classic engineering technique may improve decisions about building and using supplies of important paediatric vaccines, potentially leading to lower public health costs and healthier children…
World's first transcontinental anaesthesia
— 11:25 GMT | HealthVideoconferences may be known for putting people to sleep, but never like this. Dr Thomas Hemmerling and his team of McGill's Department of Anaesthesia achieved a world first on August 30, 2010, when they treated patients undergoing thyroid gland surgery in Italy remotely from Montreal. The approach is part of new technological advancements, known as 'Teleanaesthesia,' and it involves a team of engineers, researchers and anaesthesiologists who will ultimately apply the drugs intravenously which are then controlled remotely through an automated system…
Graphene may hold key to speeding up DNA sequencing
— 11:22 GMT | TechnologyIn a paper published as the cover story of the September 9, 2010 Nature, researchers from Harvard University and MIT have demonstrated that graphene, a surprisingly robust planar sheet of carbon just one-atom thick, can act as an artificial membrane separating two liquid reservoirs…
Many roads lead to superconductivity
— 11:19 GMT | TechnologySince their discovery in 2008, a new class of superconductors has precipitated a flood of research the world over. Unlike the previously familiar copper ceramics (cuprates), the basic structure of this new class consists of iron compounds. Because the structure of these compounds differs from the cuprates in many fundamental ways, there is hope of gaining new insights into how the phenomenon of superconductivity arises…
LiXEdrom: Innovative measuring chamber for X-ray study of liquid jets
— 11:16 GMT | TechnologyX-rays are the medium of choice for many scientific studies. When you shine them on a sample, they literally shed light on the material's structure, providing loads of information about it. Unfortunately, this mostly applies to solids only, since the sample has to be in a vacuum for the entire time it is being irradiated with soft X-rays. For liquids, that means you have to remove all the water. In the case of biological samples such as proteins, however, this destroys their natural environment. The solution to this problems has always been to measure liquids through membranes. These membranes keep the evacuated side separate from the non-evacuated side. The trouble is, one can never really be sure whether or not membrane effects are distorting the measurement results…
Discovery offers hope of saving sub-Saharan crops from devastating parasites
— 11:13 GMT | EnvironmentEach year, thousands of acres of crops are planted throughout Africa, Asia and Australia only to be laid to waste by a parasitic plant called Striga, also known as witchweed. It is one of the largest challenges to food security in Africa, and a team of scientists led by researchers from the University of Toronto have discovered chemicals and genes that may break Striga's stranglehold…
OU study on genetics in fruit flies leads to new method for understanding brain function
— 11:10 GMT | HealthA team of University of Oklahoma researchers studying neurobiology in fruit flies (Drosophila) has developed a new method for understanding brain function with potential applications in studies of human neurological diseases…
