International team finds key gene that allows plants to survive drought
— 17:30 GMT | BiologyA team of scientists from Canada, Spain and the United States has identified a key gene that allows plants to defend themselves against environmental stresses like drought, freezing and heat…
Contrary to recent hypothesis, 'chevrons' are not evidence of megatsunamis
— 17:27 GMT | EnvironmentA persistent school of thought in recent years has held that so-called 'chevrons,' large U- or V-shaped formations found in some of the world's coastal areas, are evidence of megatsunamis caused by asteroids or comets slamming into the ocean…
Protein central to both Parkinson's, drug addiction identified
— 17:25 GMT | HealthResearchers have identified a protein that appears not only to be central to the process that causes Parkinson's disease but could also play a role in muting the high from methamphetamine and other addictive drugs…
U of Minnesota researcher helps develop new technique for modifying plant genes
— 17:22 GMT | BiologyResearchers at the University of Minnesota and Massachusetts General Hospital have used a genome engineering tool they developed to make a model crop plant herbicide-resistant without significant changes to its DNA…
Emotional support leads to sporting success
— 17:20 GMT | HealthSportsmen and women could get the edge on their opponents by accepting more emotional support in their personal and professional lives. A study by the University of Exeter, published in the Journal of Applied Sport Psychology, shows the extent to which a sympathetic ear or regular words of encouragement can improve sports performance…
World's largest DNA scan for autism uncovers new gene variant for disorder
— 17:17 GMT | HealthUCLA scientists, in partnership with 30 research institutions across the country, have identified a new gene variant that is highly common in autistic children. And when researchers scrutinised the activity of the gene, known as CDH10, in the foetal brain, they discovered that it is most active in key regions that support language, speech and interpreting social behaviour…
Researchers design unique method to induce immunity to certain STDs

Gene test determines risk of heart surgery complications
— 17:12 GMT | HealthGenetic differences can explain why some patients undergoing heart surgery later experience shock and kidney complications, according to a study by researchers at the Charite - Universitaetsmedizin Berlin, the Max-Delbrueck-Centre for Molecular Medicine (MDC) Berlin-Buch in Germany and the Austin Hospital in Melbourne, Australia. The results indicate that performing a genetic test on patients before they have surgery can help guide treatment after they leave the operating room…
Excessive increase in heart rate before exercise doubles risk of sudden cardiac death

NASA's electronic nose may provide neurosurgeons with a new weapon against brain cancer
— 17:07 GMT | HealthAn unlikely multidisciplinary scientific collaboration has discovered that an electronic nose developed for air quality monitoring on Space Shuttle Endeavour can also be used to detect odour differences in normal and cancerous brain cells. The results of the pilot study open up new possibilities for neurosurgeons in the fight against brain cancer…
