'Land Grabs' For Rice Production Due To Supply Threats
Recent interest in “land grabs” or the international acquisition of land to produce rice is sparked by a looming threat of inadequate rice supplies. To put it simply, there is not enough rice to feed the world,” says Dr. Robert Zeigler, director general of the International Rice Research Institute (IRRI). “To meet the need and keep rice prices around US$300 a ton – which allows poor rice farmers to make some profit yet keeps rice affordable for poor rice consumers – we need to produce an additional 8–10 million tons of rice more...
Genetic Link to Heart Failure
A team of researchers, at Washington University School of Medicine, St Louis, has identified a group of 12 genetic variants in the HSPB7 gene that is associated with heart failure in humans. The research is reported in the Journal of Clinical Investigation. The team, led by Gerald Dorn, used an approach they have recently developed that allows ultra-high-throughput targeted DNA sequencing to identify genetic variation in four genes with biological relevance to heart failure. They identified in a large group of Caucasian individu...
Biofilms: Researchers Discover New Ways to Treat Chronic Infections
Researchers at Binghamton University, State University of New York, have identified three key regulators required for the formation and development of biofilms. The discovery could lead to new ways of treating chronic infections. Biofilms -- communities of bacteria in self-produced slime -- may be found almost anywhere that solids and liquids meet, whether in nature, in hospitals or in industrial settings. Biofilms are implicated in more than 80 percent of chronic inflammatory and infectious diseases caused by bacteria, including ear infecti...
Keeping Hepatitis C Virus at Bay After a Liver Transplant
One of the most common reasons for needing a liver transplant is liver failure or liver cancer caused by liver cell infection with hepatitis C virus (HCV). However, in nearly all patients the new liver becomes infected with HCV almost immediately. But now, Hideki Ohdan, Kazuaki Chayama, and colleagues, at Hiroshima University, Japan, have developed an approach that transiently keeps HCV levels down in most treated HCV-infected patients receiving a new liver. The researchers report their findings in the Journal of Clinical Investigation....
Looking Back in Time 12 Billion Years With New Instruments on Herschel Space Observatory
An instrument package developed in part by the University of Colorado at Boulder for the $2.2 billion orbiting Herschel Space Observatory launched in May by the European Space Agency has provided one of the most detailed views yet of space up to 12 billion years back in time. The December images have revealed thousands of newly discovered galaxies in their early stages of formation, said CU-Boulder Associate Professor Jason Glenn, a co-investigator on the Spectral and Photometric Imaging Receiver, or SPIRE instrument, riding aboard Hers...
