| New nano-material combinations produce leap in infrared technology Posted: 14 Feb 2012 11:53 AM PST Researchers are using new combinations of nano-materials to produce advances in infrared photodetection technology.  |
| Tangled up in DNA: New molecule has potential to help treat genetic diseases and HIV Posted: 14 Feb 2012 10:49 AM PST Chemists have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.  |
| 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.  |
| 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.  |
| Globular clusters: Survivors of a 13-billion-year-old massacre Posted: 14 Feb 2012 07:08 AM PST Our Milky Way galaxy is surrounded by some 200 compact groups of stars, containing up to a million stars each. At 13 billion years of age, these globular clusters are almost as old as the universe itself and were born when the first generations of stars and galaxies formed. Now astronomers have conducted a novel type of computer simulation that looked at how they were born -- and they find that these giant clusters of stars are the only survivors of a 13-billion-year-old massacre that destroyed many of their smaller siblings.  |
| Turmeric-based drug effective on Alzheimer flies Posted: 14 Feb 2012 07:05 AM PST Curcumin, a substance extracted from turmeric, prolongs life and enhances activity of fruit flies with a nervous disorder similar to Alzheimer's disease, according to new research. The study indicates that it is the initial stages of fibril formation and fragments of the amyloid fibrils that are most toxic to neurons.  |
