| Posted: 21 Jul 2011 11:24 AM PDT Recently, researchers at New York University demonstrated an ability to make new materials with empty space on the inside, which could potentially control desired and unwanted chemical reactions.  |
| Exoplanet aurora: An out-of-this-world sight Posted: 21 Jul 2011 10:12 AM PDT Earth's aurorae, or Northern and Southern Lights, provide a dazzling light show to people living in the polar regions. Shimmering curtains of green and red undulate across the sky like a living thing. New research shows that aurorae on distant "hot Jupiters" could be 100-1000 times brighter than Earthly aurorae. They also would ripple from equator to poles (due to the planet's proximity to any stellar eruptions), treating the entire planet to an otherworldly spectacle.  |
| Modified metals change color in the presence of particular gases Posted: 21 Jul 2011 10:11 AM PDT Modified metals that change color in the presence of particular gases could warn consumers if packaged food has been exposed to air or if there's a carbon monoxide leak at home.  |
| Robots to check inside the innards of nuclear reactors Posted: 21 Jul 2011 08:26 AM PDT Scientists have develop robots equipped with cameras that can navigate the underground pipes of a nuclear reactor to check for corrosion by propelling themselves with internal networks of valves and pumps.  |
| Cosmological evolution of dark matter is similar to that of visible matter Posted: 21 Jul 2011 07:20 AM PDT Large cosmic structures made up of dark and normal matter evolve along the same lines – this is one of the most important conclusions emerging from the latest computer simulations.  |
| New discovery paves the way for using super strong nanostructured metals in cars Posted: 21 Jul 2011 07:14 AM PDT Super strong nanometals are beginning to play an important role in making cars even lighter, enabling them to stand collisions without fatal consequences for the passengers. A student has discovered a new phenomenon that will make nanometals more useful in practice.  |
| Four unusual views of the Andromeda Galaxy Posted: 21 Jul 2011 06:58 AM PDT The Andromeda Galaxy is revealed in unprecedented detail in four archive observations. They show stars and structure in the galaxy's disc, the halo of stars that surrounds it, and a stream of stars left by a companion galaxy as it was torn apart and pulled in by the galaxy's gravitational forces.  |
