| Posted: 25 Jan 2013 08:13 AM PST Using a mathematical model based on natural evolution, researchers have developed an organic solar cell design that could pave the way for more efficient, less expensive solar energy.  |
| Diet, parental behavior and preschool can boost children's IQ Posted: 25 Jan 2013 08:13 AM PST Supplementing children's diets with fish oil, enrolling them in quality preschool, and engaging them in interactive reading all turn out to be effective ways to raise a young child's intelligence, according to a new report.  |
| More than one brain behind Einstein's famous equation: E=mc2 Posted: 25 Jan 2013 07:39 AM PST A new study reveals the contribution of a little known Austrian physicist, Friedrich Hasenöhrl, to uncovering a precursor to Einstein's famous equation. Two American physicists outline the role played by Austrian physicist Friedrich Hasenöhrl in establishing the proportionality between the energy (E) of a quantity of matter with its mass (m) in a cavity filled with radiation.  |
| Posted: 25 Jan 2013 07:39 AM PST Policymakers are attempting to contain global warming at less than 2°C. New estimates from a Norwegian project on climate calculations indicate this target may be more attainable than many experts have feared.  |
| Origin and maintenance of a retrograde exoplanet Posted: 25 Jan 2013 07:39 AM PST Astronomers have shown that the HAT-P-7 planetary system, which is about 1040 light-years from Earth in the constellation Cygnus, includes at least two giant planets and one companion star. The discovery of a previously unknown companion (HAT-P-7B) to the central star (HAT-P-7) as well as confirmation of another giant planet (HAT-P-7c) orbiting outside of the retrograde planet HAT-P-7b, offer new insights into how retrograde planets may form and endure.  |
| Thawing 'dry ice' drives groovy action on Mars Posted: 25 Jan 2013 06:53 AM PST Researchers using NASA's Mars Reconnaissance Orbiter see seasonal changes on far-northern Martian sand dunes caused by warming of a winter blanket of frozen carbon dioxide.  |
| Magnetic levitation tissues could speed toxicity tests Posted: 24 Jan 2013 03:36 PM PST In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory.  |
| Drinking water unexpectedly rich in microbial life Posted: 24 Jan 2013 06:14 AM PST Flow cytometry can now be officially used for the quantification of microbial cells in drinking water. The new analytical method provides much more realistic results than the conventional method, in which bacterial colonies are grown on agar plates. The results demonstrate that even good-quality drinking water harbors 100 to 10,000 times more living cells than the conventional plate count method would suggest.  |
