Isolating a gene that allows a type of fern to tolerate high levels of arsenic, Purdue University researchers hope to use the finding to create plants that can clean up soils and waters contaminated by the toxic metal.The fern Pteris vittata can tolerate 100 to 1,000 times more arsenic than other plants.

Posted by Siril on January 20th, 2010
Romance may happen every day, but finding true love in London is as rare as aliens in the galaxy, says one London-based economist. Peter Backus, a teaching fellow of economics at the University of Warwick, has calculated that he has a 0.00034 percent chance of finding love in the British capital using the same “Drake” [...]
German scientists develop fast-acting germ killer
Posted by Siril on January 20th, 2010
A new fast-acting disinfectant that is effective against bacteria, viruses and other germs could help stop the spread of deadly infections in hospitals, German scientists said on Wednesday. Researchers from the Robert Koch Institute in Berlin said they had developed a fast-acting, practical formula which would kill germs on surgical instruments without damaging them through [...]
Exotic Symmetry Seen in Ultracold Electrons
Posted by Siril on January 20th, 2010
An exotic type of symmetry — suggested by string theory and theories of high-energy particle physics, and also conjectured for electrons in solids under certain conditions — has been observed experimentally for the first time. An international team, led by scientists from Oxford University, report in a recent article in Science how they spotted the [...]
Common Stomach Pathogen May Protect Against Tuberculosis
Posted by Siril on January 20th, 2010
It’s been implicated as the bacterium that causes ulcers and the majority of stomach cancers, but studies by researchers at Stanford University, UC Davis, and the University of Pittsburgh have found that Helicobacter pylori (H. pylori) also may play a protective role — against the worldwide killer, tuberculosis (TB). In an article appearing online in [...]
