| BOSS quasars unveil a new era in the expansion history of the universe Posted: 12 Nov 2012 07:43 PM PST BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on the spectra of over 48,000 quasars with redshifts up to 3.5, meaning that light left these active galaxies up to 11.5 billion years in the past. |
| Meditation appears to produce enduring changes in emotional processing in the brain Posted: 12 Nov 2012 12:03 PM PST A new study has found that participating in an eight-week meditation training program can have measurable effects on how the brain functions even when someone is not actively meditating. The researchers also found differences in those effects based on the specific type of meditation practiced. |
| Posted: 12 Nov 2012 10:56 AM PST Researchers have created a hybrid nanomaterial that can be used to convert light and thermal energy into electrical current. The team built a prototype thermoelectric generator they hope can eventually produce milliwatts for use in devices such as self-powering sensors, low-power electronic devices and implantable biomedical micro-devices, they said. They have also coupled gold nanoparticles with copper sulfide nanoparticles for potential use in cancer therapy. |
| Infants mimic unusual behavior when accompanied by language Posted: 12 Nov 2012 10:56 AM PST A new study shows the power of language in infants' ability to understand the intentions of others. The results, based on two experiments, show that introducing a novel word for the impending novel event had a powerful effect on the infants' tendency to imitate the behavior. Infants were more likely to imitate behavior, however unconventional, if it had been named, than if it remained unnamed, the study shows. |
| Posted: 12 Nov 2012 06:59 AM PST Using the power of the sun and ultrathin films of iron oxide, Israeli researchers have found a novel way to split water molecules into hydrogen and oxygen. The breakthrough could lead to less expensive, more efficient ways to store solar energy in the form of hydrogen-based fuels. |
| Mongolia and the Altai Mountains: Origins of genetic blending between Europeans and Asians Posted: 12 Nov 2012 06:04 AM PST A group of researchers has discovered the first scientific evidence of genetic blending between Europeans and Asians in the remains of ancient Scythian warriors living over 2,000 years ago in the Altai region of Mongolia. Contrary to what was believed until now, the results indicate that this blending was not due to an eastward migration of Europeans, but to a demographic expansion of local Central Asian populations, thanks to the technological improvements the Scythian culture brought with them. |
