Detecting lethal diseases with rust and sand
— 31 Jan 2011 | HealthThe next big thing in medical diagnostics could be minutes particles of rust, iron oxide, coated with the material from which sand is formed, silicon dioxide. These magnetic nanoparticles, a mere 29 to 230 nanometres across, can be used to trap antibodies to the virus that causes cervical cancer and to the bacteria that causes potentially lethal diarrhoea…
Seeing kidney injury, as it happens
— 31 Jan 2011 | HealthThe current check for kidney disease is a simple blood test for serum creatinine, but it can take longer than two days for this metabolite to accumulate to levels that are significant enough to indicate kidney damage - and by then it may be too late to intervene…
New transistors: An alternative to silicon and better than graphene
— 30 Jan 2011 | TechnologySmaller and more energy-efficient electronic chips could be made using molybdenite. In an article appearing online January 30 in the journal Nature Nanotechnology, EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) publishes a study showing that this material has distinct advantages over traditional silicon or graphene for use in electronics applications…
Salk researchers discover that stem cell marker regulates synapse formation
— 30 Jan 2011 | BiologyAmong stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a 'stem cell,' such as a neural stem cell. As helpful as this is to researchers, until now no one knew which purpose nestin serves in a cell…
Researchers discover root cause of blood vessel damage in diabetes
— 29 Jan 2011 | HealthA key mechanism that appears to contribute to blood vessel damage in people with diabetes has been identified by researchers at Washington University School of Medicine in St. Louis…
More frequent drought likely in eastern Africa
— 29 Jan 2011 | EnvironmentThe increased frequency of drought observed in eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to new research published in Climate Dynamics…
Fast growth, low defence - plants facing a dilemma
— 29 Jan 2011 | BiologyPlants are attacked by a multitude of insects and mammals. As defence against these herbivores they developed complex defence mechanisms over the course of evolution: spines, thorns, leaf hairs and a number of toxic chemical substances. For decades it has been controversially discussed whether the production of defence traits incurs costs to the plants. Now, using a new method the ecologists and plant biologists of the University of Zuerich together with their American colleagues demonstrate these costs accurately in a Proceedings of the Royal Society article…
Study: African-American men say doctor visits are often a bad experience
— 29 Jan 2011 | HealthA majority of African American men said they do not go to the doctor because visits are stressful and physicians don't give adequate information on how to make prescribed behaviour or lifestyle changes, a new University of Michigan study shows…
Powerful 3-D X-rays for kids in braces should be the exception, not the rule
— 29 Jan 2011 | HealthSome orthodontists may be exposing young patients to unnecessary radiation when they order 3-D X-ray imaging for simple orthodontic cases before considering traditional 2-D imaging, suggests a paper published by University of Michigan faculty…
