| 'Amplified' nanotubes may power the future Posted: 14 Jul 2011 04:15 PM PDT Scientists have achieved a pivotal breakthrough in the development of a cable that will make an efficient electric grid of the future possible. Armchair quantum wire (AQW) will be a weave of metallic nanotubes that can carry electricity with negligible loss over long distances. It will be an ideal replacement for the nation's copper-based grid, which leaks electricity at an estimated 5 percent per 100 miles of transmission.  |
| Posted: 14 Jul 2011 10:31 AM PDT Researchers have found a way to grow submicroscopic wires in water with great precision, using a method that makes it possible to produce entire electronic devices through a liquid-based process.  |
| New planets feature young star and twin Neptunes Posted: 14 Jul 2011 07:24 AM PDT Scientists have discovered 10 new planets. Amongst them is one orbiting a star perhaps only a few tens of million years old, twin Neptune-sized planets, and a rare Saturn-like world.  |
| Most elliptical galaxies are 'like spirals' Posted: 14 Jul 2011 07:16 AM PDT The majority of 'elliptical' galaxies are not spherical but disc-shaped, resembling spiral galaxies such as our own Milky Way with the gas and dust removed, new observations suggest.  |
| Soft memory device opens door to new biocompatible electronics Posted: 14 Jul 2011 07:15 AM PDT Researchers have developed a memory device that is soft and functions well in wet environments -- opening the door to a new generation of biocompatible electronic devices.  |
| Print your own teeth: Rapid prototyping comes to dentistry Posted: 14 Jul 2011 07:15 AM PDT What if, instead of waiting days or weeks for a cast to be produced and prosthetic dental implants, false teeth and replacement crowns to be made, your dentist could quickly scan your jaw and "print" your new teeth using a rapid prototyping machine known as a 3-D printer?  |
| Galaxy-sized twist in time pulls violating particles back into line Posted: 14 Jul 2011 04:24 AM PDT A physicist in the UK has produced a galaxy-sized solution that explains one of the outstanding puzzles of particle physics, while leaving the door open to the related conundrum of why different amounts of matter and antimatter seem to have survived the birth of our Universe. Physicists would like a neat universe where the laws of physics are so universal that every particle and its antiparticle behave in the same way.  |
