World's fastest camera relies on an entirely new type of imaging
— 14:58 GMT | TechnologyUltrafast, light-sensitive video cameras are needed for observing high-speed events such as shockwaves, communication between living cells, neural activity, laser surgery and elements of blood analysis. To catch such elusive moments, a camera must be able to capture millions or billions of images continuously with a very high frame rate. Conventional cameras are simply not up to the task…
Online survey of public to help study of how disease and pandemics spread

Researchers demonstrate first common genetic risk factors for autism
— 13:46 GMT | HealthResearchers have made an important step forward in understanding the complex genetic structure of autism spectrum disorders. A researcher collaboration, including geneticists from the University of Pennsylvania School of Medicine and The Children's Hospital of Philadelphia (CHOP), have detected variations along a genetic pathway that is responsible for neurological development, learning and memory, which appears to play a significant role in the genetic risk of autism. Their findings were published online in the journal Nature on 28 April…

Published in the May issue of the American Journal of Psychiatry, the study suggests only a small percentage of people with depression qualify for these studies, and those who do not qualify are often treated with the same medications but may suffer poorer clinical outcomes…
Older men more likely than women to die after pneumonia
— 13:38 GMT | HealthDiffering biological response to infection between men and women may explain higher death rates among older men who are hospitalised with community-acquired pneumonia (CAP). The findings, published online in the Critical Care Medicine journal, may have important implications for understanding sex differences in life expectancy…

Nanoneedle is small in size, but huge in applications
— 13:31 GMT | TechnologyResearchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. In addition to ferrying tiny amounts of cargo, the nanoneedle can also be used as an electrochemical probe and as an optical biosensor…
When industrious ants go too far
— 13:28 GMT | BiologyNature is full of mutually beneficial arrangements between organisms - like the relationship between flowering plants and their bee pollinators. But sometimes these blissful relationships have a dark side, as Harvard biologist Megan Frederickson describes in an article for the May issue of The American Naturalist…
