A new way to weigh planets (October 23, 2010) -- Astronomers have developed a new way to weigh the planets in our solar system -- using radio signals from the small spinning stars called pulsars. ... > full story
Nanotube thermopower: Efforts to store energy in carbon nanotubes (October 23, 2010) -- Researchers from Massachusetts have found a way to store energy in thin carbon nanotubes by adding fuel along the length of the tube, chemical energy, which can later be turned into electricity by heating one end of the nanotubes. ... > full story
Scientists open electrical link to living cells (October 23, 2010) -- The Terminator. The Borg. The Six Million Dollar Man. Science fiction is ripe with biological beings armed with artificial capabilities. In reality, however, the clunky connections between living and non-living worlds often lack a clear channel for communication. Now scientists have designed an electrical link to living cells engineered to shuttle electrons across a cell's membrane. This direct channel could yield cells that can read and respond to electronic signals, or efficiently transfer sunlight into electricity. ... > full story
Short-range scattering in quantum dots: Discovery advances novel devices (October 23, 2010) -- Chinese researchers have described a new breakthrough in understanding the way electrons travel around quantum dots. This might lead to promising new fabrication methods of novel quantum devices. ... > full story
Chemical engineers use gold to discover breakthrough for creating biorenewable chemicals (October 23, 2010) -- Chemical engineers have uncovered the key features that control the high reactivity of gold nanoparticles in a process that oxidizes alcohols in water. The research is an important first step in unlocking the potential of using metal catalysts for developing biorenewable chemicals. The scientific discovery could one day serve as the foundation for creating a wide range of consumer products from biorenewable carbon feedstocks, as opposed to the petroleum-based chemicals currently being used as common building blocks for commodities such as cosmetics, plastics, pharmaceuticals and fuels. ... > full story
New cometary phenomenon greets approaching spacecraft (October 22, 2010) -- Recent observations of comet Hartley 2 have scientists scratching their heads, while they anticipate a flyby of the small, icy world on Nov. 4. A phenomenon was recorded by imagers aboard NASA's Deep Impact spacecraft from Sept. 9 to 17 during pre-planned scientific observations of the comet. These observations, when coupled with expected images during the closest encounter with Hartley 2 on Nov. 4, will become the most detailed look yet at a comet's activity during its pass through the inner-solar system. ... > full story
Value-added sulfur scrubbing: Converting acid rain chemicals into useful products (October 22, 2010) -- Power plants that burn fossil fuels remain the main source of electricity generation across the globe. Modern power plants have scrubbers to remove sulfur compounds from their flue gases, which has helped reduce the problem of acid rain. Now, researchers in India have devised a way to convert the waste material produced by the scrubbing process into value-added products. ... > full story
Space telescopes reveal previously unknown brilliant X-ray explosion in Milky Way galaxy (October 22, 2010) -- Astronomers in Japan, using an X-ray detector on the International Space Station, and in the United States, using NASA's Swift space observatory, are announcing the discovery of an object newly emitting X-rays, which previously had been hidden inside our Milky Way galaxy in the constellation Centaurus. ... > full story
Researchers break speed barrier in solving important class of linear systems (October 22, 2010) -- Computer scientists have devised an innovative and elegantly concise algorithm that can efficiently solve systems of linear equations that are critical to such important computer applications as image processing, logistics and scheduling problems, and recommendation systems. ... > full story
Towards better explosives detectors (October 22, 2010) -- Over the past decade, a team of scientists in Maryland have been working to stop the threat of terrorist-based attacks in the form of explosives or explosive-based devices, by providing a sound measurement and standard infrastructure. ... > full story
Lunar 'permafrost': Evidence for widespread water ice on the moon (October 22, 2010) -- Scientists from NASA's Diviner Lunar Radiometer Experiment team have detected the widespread presence of water ice in large areas of the moon's south pole. This lunar 'permafrost' is analogous to the high-latitude terrain found on the Earth and on Mars, where subfreezing temperatures persist below the surface throughout the year, scientists say. ... > full story
Spotting suspicious moles (October 22, 2010) -- Most of the spots on our skin are perfectly harmless moles, collections of cells called melanocytes. But occasionally, these melanocytes turn cancerous, creating the potentially deadly skin tumor melanoma. Scientists have now developed a new technique that aims to help doctors distinguish melanomas from harmless moles using high-resolution snapshots of suspicious spots. ... > full story
