New pathway to valleytronics: Femtosecond laser used to manipulate valley excitons Posted: 27 Jan 2015 09:24 AM PST Researchers have uncovered a promising new pathway to valleytronics, a potential quantum computing technology in which information is coded based on the wavelike motion of electrons moving through certain 2-D semiconductors.

Web surfing to weigh up bariatric surgery options Posted: 27 Jan 2015 08:10 AM PST Obese people considering weight-reducing surgery are only topped by pregnant women when it comes to how often they turn to the Internet for health advice. While most use it to read up on relevant procedures and experiences, some patients actually chooses a surgeon based solely on what they have gleaned from the web, a study concludes.

New search engine lets users look for relevant results faster Posted: 27 Jan 2015 08:09 AM PST Researchers have developed a new search engine that outperforms current ones, and helps people to do searches more efficiently.

Bad weather warnings most effective if probability included, new research suggests Posted: 27 Jan 2015 07:48 AM PST Risk researchers find that the public may respond best to severe weather warnings if they include a probability estimate, an important finding not only for the present but also for the longer-term future as climate change brings more frequent and severe threats.
