| Saturn's geyser moon Enceladus provides a new kind of plasma laboratory Posted: 01 Jun 2012 09:21 AM PDT Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed "dusty plasma," a condition theorized but not previously observed on site, near Enceladus. Data from Cassini's fields and particles instruments also show that the usual "heavy" and "light" species of charged particles in normal plasma are actually reversed near the plume spraying from the moon's south polar region.  |
| Quantum computers will be able to simulate particle collisions Posted: 01 Jun 2012 09:06 AM PDT Quantum computers are still years away, but a trio of theoretical physicists can already make the claim "there's an app for that." The theorists have developed a mathematical algorithm that will be used by a future quantum computer to study the inner workings of the universe in ways that are far beyond the reach of even the most powerful conventional supercomputers.  |
| Posted: 01 Jun 2012 09:06 AM PDT The current theory of continental drift provides a good model for understanding terrestrial processes through history. However, while plate tectonics is able to successfully shed light on processes up to three billion years ago, the theory isn't sufficient in explaining the dynamics of Earth and crust formation before that point and through to the earliest formation of planet, some 4.6 billion years ago.  |
| Astronomers discover faintest distant galaxy Posted: 01 Jun 2012 09:06 AM PDT Astronomers have found an exceptionally distant galaxy, ranked among the top 10 most distant objects currently known in space. Light from the recently detected galaxy left the object about 800 million years after the beginning of the universe, when the universe was in its infancy. The team of astronomers identified the remote galaxy after scanning a moon-sized patch of sky with an instrument on the Magellan Telescopes at the Las Campanas Observatory in Chile.  |
| Nanotechnology breakthrough could dramatically improve medical tests Posted: 31 May 2012 01:57 PM PDT A laboratory test used to detect disease and perform biological research could be made more than 3 million times more sensitive, according to researchers who combined standard biological tools with a breakthrough in nanotechnology.  |
