| Sombrero galaxy has split personality Posted: 24 Apr 2012 01:14 PM PDT While some galaxies are rotund and others are slender disks like our spiral Milky Way, new observations from NASA's Spitzer Space Telescope show that the Sombrero galaxy is both. The galaxy, which is a round elliptical galaxy with a thin disk embedded inside, is one of the first known to exhibit characteristics of the two different types. The findings will lead to a better understanding of galaxy evolution, a topic still poorly understood.  |
| Study finds surprising Arctic methane emission source Posted: 24 Apr 2012 11:51 AM PDT The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study has uncovered a surprising and potentially important new source of Arctic methane: the ocean itself.  |
| Vibrating steering wheel guides drivers while keeping their eyes on the road Posted: 24 Apr 2012 11:23 AM PDT A vibrating steering wheel is an effective way to keep a driver's eyes safely on the road by providing an additional means to convey directions from a car's navigation system, researchers have shown.  |
| Cassini sees new objects blazing trails in Saturn ring Posted: 24 Apr 2012 09:08 AM PDT Scientists have discovered strange half-mile-sized objects punching through parts of Saturn's F ring, leaving glittering trails behind them. These trails in the rings, which scientists are calling 'mini-jets', fill in a missing link in our understanding of the curious behaviour of the F ring.  |
| Creating nano-structures from the bottom up Posted: 24 Apr 2012 09:07 AM PDT Microscopic particles are being coaxed by engineers to assemble themselves into larger crystalline structures by the use of varying concentrations of microscopic particles and magnetic fields.  |
| New concept for fast, low-cost DNA sequencing device Posted: 24 Apr 2012 09:04 AM PDT Researchers have developed a new concept for use in a high-speed genomic sequencing device that may have the potential to substantially drive down costs.  |
| Did exploding stars help life on Earth thrive? Posted: 24 Apr 2012 06:56 AM PDT Research by a Danish physicist suggests that the explosion of massive stars -- supernovae -- near the Solar System has strongly influenced the development of life.  |
