Anammox bacteria produce nitrogen gas in oceans' snackbar

Thirty to fifty percent of the global conversion of nutrients to nitrogen gas occurs in these areas. In 'The Proceedings of the National Academy of Science of the United States (PNAS)' of Tuesday 19 April, researchers from Bremen and Nijmegen state that this conversion is not carried out by denitrifying bacteria, as was believed for decades, but by anammox bacteria. Nitrogen compounds act as fert...

Researchers at UGA provide first look at protein expression in Chagas disease-causing parasites

Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. Ralph Liedert from the University of Applied Sciences, Bremen, Germany, is presenting his work on t...

Ancient DNA confirms single origin of Malagasy primates

Yale biologists have managed to extract and analyze DNA from giant, extinct lemurs, according to a Yale study published in a recent issue of the Proceedings of the National Academy of Sciences. Radiocarbon dating of the bones and teeth from which the DNA was obtained reveal that each of the individuals analyzed died well over 1,000 years ago, according to the senior author, Anne Yoder, ass...

Plants used to detect gas leaks, from outer space!

Gas leaks can be potentially life threatening in the home, but the presence of gas stresses out plants too. Professor Mike Steven and colleagues from the University of Nottingham have found that changes in the physical properties of plants can act as an early warning of leaks in natural gas pipelines. "Our study was about testing the ability of satellite remote systems to monitor gas le...

Food-crop yields in future greenhouse-gas conditions lower than expected

Open-air field trials involving five major food crops grown under carbon-dioxide levels projected for the future are harvesting dramatically less bounty than those raised in earlier greenhouse and other enclosed test conditions ?and scientists warn that global food supplies could be at risk without changes in production strategies. The new findings are based on on-going open-air research a...

Antidepressants increase gastric bleeding

A new survey suggests that certain antidepressants increase the risk of a gastrointestinal bleed in older patients. The selective serotonin reuptake inhibitors (SSRIs) are a group of antidepressants which are very widely prescribed. They are preferred over older drugs because they are relatively free of side effects. But, as Researchers at Ottawa Hospital in Canada have just shown, they a...
