| Report seeks to integrate microbes into climate models Posted: 14 Feb 2012 11:53 AM PST The models used to understand how Earth's climate works include thousands of different variables from many scientific including atmospherics, oceanography, seismology, geology, physics and chemistry, but few take into consideration the vast effect that microbes have on climate. Now, a new report offers a plan for integrating the latest understanding of the science of microbiology into climate models.  |
| Proteins in Yellowstone bacteria considered for biofuel inspiration Posted: 14 Feb 2012 11:53 AM PST Studies of bacteria first found in Yellowstone's hot springs are furthering efforts toward commercially viable ethanol production from crops such as switchgrass.  |
| Noncoding RNAs alter yeast phenotypes in a site-specific manner Posted: 14 Feb 2012 11:53 AM PST Scientists have shown for the first time how two long intergenic noncoding RNAs in brewer's yeast contribute to a location-dependent switch for the yeast FLO11 gene to toggle between active and inactive states.  |
| Chemists mimic nature to design better medical tests Posted: 14 Feb 2012 10:49 AM PST Over their 3.8 billion years of evolution, living organisms have developed countless strategies for monitoring their surroundings. Chemists have adapted some of these strategies to improve the performance of DNA detectors. Their findings may aid efforts to build better medical diagnostics, such as improved HIV or cancer tests.  |
| Sobering future of wildfire dangers in U.S. west, researchers predict Posted: 14 Feb 2012 10:49 AM PST The American West has seen a recent increase in large wildfires due to droughts, the build-up of combustible fuel, or biomass, in forests, a spread of fire-prone species and increased tree mortality from insects and heat. A research team warns that these conditions may be "a perfect storm" for more fires.  |
| Bumblebees get by with a little help from their honeybee rivals Posted: 14 Feb 2012 09:18 AM PST Bumblebees can use cues from their rivals the honeybees to learn where the best food resources are, according to new research. In a new study, researchers trained a colony of bumblebees (Bombus terrestris) to use cues provided by a different species, the honeybee (Apis mellifera), as well as cues provided by fellow bumblebees to locate food resources on artificial flowers.  |
| Critical stage of embryonic development now observable Posted: 14 Feb 2012 09:18 AM PST A novel approach in the study of the development of mammalian embryos has just been developed. The research enables scientists to view critical aspects of embryonic development which was previously unobservable.  |
| Fukushima at increased earthquake risk, scientists report Posted: 14 Feb 2012 07:08 AM PST Seismic risk at the Fukushima nuclear plant increased after the magnitude 9 earthquake that hit Japan last March, scientists report. The new study, which uses data from over 6,000 earthquakes, shows the 11 March tremor caused a seismic fault close to the nuclear plant to reactivate. The research suggests authorities should strengthen the security of the Fukushima Daiichi nuclear power plant to withstand large earthquakes that are likely to directly disturb the region.  |
| 'Invisibility' cloak could protect buildings from earthquakes Posted: 14 Feb 2012 07:08 AM PST Mathematicians have developed the theory for a Harry Potter style 'cloaking' device which could protect buildings from earthquakes. Scientists have been working on the theory of invisibility cloaks which, until recently, have been merely the subject of science fiction. In recent times, however, scientists have been getting close to achieving 'cloaking' in a variety of contexts. The new work focuses on the theory of cloaking devices which could eventually help to protect buildings and structures from vibrations and natural disasters such as earthquakes.  |
| Posted: 13 Feb 2012 10:34 AM PST An expert says that a genome, rather than a static collection of information, is a dynamic structure itself, responding to stress and contributing to our genetic development. His re-conception of the genome has the potential to provide deeper insight into how all living organisms evolve.  |
