New imaging method sheds light on cell growth Posted: 25 Aug 2011 02:25 PM PDT Researchers developed a new imaging method that can measure cell mass using two beams of light, offering new insight into the much-debated problem of whether cells grow at a constant rate or exponentially. They found that mammalian cells show clear exponential growth only during the G2 phase of the cell cycle. This information has great implications not only for basic biology, but also for diagnostics, drug development and tissue engineering. |
Posted: 25 Aug 2011 02:25 PM PDT The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might have different masses. A new from the MINOS experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory appears to quell concerns raised by a MINOS result in June 2010 and brings neutrino and antineutrino masses more closely in sync. |
Scientists discover an 'instant cosmic classic' supernova Posted: 25 Aug 2011 01:49 PM PDT A supernova discovered August 24 is closer to Earth -- approximately 21 million light-years away -- than any other of its kind in a generation. Astronomers believe they caught the supernova within hours of its explosion, a rare feat made possible with a specialized survey telescope and state-of-the-art computational tools. |
Milky Way's halo raining ionized gas to fuel continued star formation Posted: 25 Aug 2011 01:49 PM PDT Astrophysicists have concluded that the Milky Way will have the fuel to continue forming stars, thanks to massive clouds of ionized gas raining down from its halo and intergalactic space. The Milky Way would rapidly change its gas into stars if no supply of new matter were available to replenish the gas. |
New depiction of light could boost telecommunications channels Posted: 25 Aug 2011 01:49 PM PDT Physicists have presented a new way to map spiraling light that could help harness untapped data channels in optical fibers. Increased bandwidth would ease the burden on fiber-optic telecommunications networks taxed by an ever-growing demand for audio, video and digital media. The new model could even spur enhancements in quantum computing and other applications. |
Researchers discover superdense aluminum Posted: 25 Aug 2011 12:27 PM PDT An international research team has discovered a new material, superdense aluminum, which has never before been found on Earth. In a new paper, the researchers describe how the material can only exist under extreme pressure, similar to that found in our planet's core. |
Pulsar transformed into small planet made of diamond discovered in Milky Way Posted: 25 Aug 2011 11:16 AM PDT A once-massive star that's been transformed into a small planet made of diamond: that's what astronomers think they've found in our Milky Way. |
Earth-bound asteroids come from stony asteroids, new studies confirm Posted: 25 Aug 2011 11:16 AM PDT Researchers got their first up-close look at dust from the surface of a small, stony asteroid after the Hayabusa spacecraft scooped some up and brought it back to Earth. Analysis of these dust particles confirms a long-standing suspicion: that the most common meteorites found here on Earth, known as ordinary chondrites, are born from these stony, or S-type, asteroids. |
Exotic galaxy reveals tantalizing tale Posted: 25 Aug 2011 10:51 AM PDT A galaxy with a unique set of characteristics is helping astronomers understand processes that probably were more common when the universe was much younger. |
Posted: 25 Aug 2011 09:43 AM PDT Researchers have led the development of a technique called HARPES, for Hard X-ray Angle-Resolved PhotoEmission Spectroscopy, that enables the study of electronic structures deep below material surfaces, including the buried layers and interfaces in nanoscale devices. This could pave the way for smaller logic elements in electronics, novel memory architectures in spintronics, and more efficient energy conversion in photovoltaic cells. |
Math-based model for deep-water oil drilling Posted: 25 Aug 2011 09:42 AM PDT A new mathematical model has applications to the study of gas kicks in deep-water oil wells, which in worst-case scenarios can lead to blowouts. |
Cars could run on recycled newspaper, scientists say Posted: 25 Aug 2011 07:50 AM PDT Here's one way that old-fashioned newsprint beats the Internet. Scientists have discovered a novel bacterial strain, dubbed "TU-103," that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline. They are currently experimenting with old editions of the Times Picayune, New Orleans' venerable daily newspaper, with great success. |
First glimpse into birth of the Milky Way Posted: 25 Aug 2011 06:02 AM PDT For almost 20 years astrophysicists have been trying to recreate the formation of spiral galaxies such as our Milky Way realistically. Now astrophysicists and astronomers present the world's first realistic simulation of the formation of our home galaxy. The new results show that there had to be stars on the outer edge of the Milky Way. |
