| 'Robot biologist' solves complex problem from scratch Posted: 13 Oct 2011 01:29 PM PDT Scientists have taken a major step toward developing robot biologists. They have shown that their system, the Automated Biology Explorer, can solve a complicated biology problem from scratch.  |
| Emulating -- and surpassing -- nature: Using DNA to build nanomaterials with desired properties Posted: 13 Oct 2011 11:18 AM PDT Scientists have learned how to top nature by building crystalline materials from nanoparticles (the "atoms") and DNA (the "bonds"). The researchers have learned how to create crystals with the particles arranged in the same types of atomic lattice configurations as some found in nature, but they also have built completely new structures that have no naturally occurring mineral counterpart. Their design rules could help improve the efficiency of optics, electronics and energy storage technologies.  |
| Carbon nanotube muscles generate giant twist for novel motors Posted: 13 Oct 2011 11:18 AM PDT Artificial muscles, based on carbon nanotubes yarn, that twist like the trunk of an elephant, but provide a thousand times higher rotation per length, have been developed by a team of researchers.  |
| New scheme for photonic quantum computing Posted: 13 Oct 2011 10:51 AM PDT The concepts of quantum technology promise to achieve more powerful information processing than is possible with even the best possible classical computers. To actually build efficient quantum computers remains a significant challenge in practice. A new scheme, called "coherent photon conversion," could potentially overcome all of the currently unresolved problems for optical implementations of quantum computing.  |
| Hubble survey carries out a dark matter census Posted: 13 Oct 2011 06:13 AM PDT The NASA/ESA Hubble Space Telescope has been used to make an image of galaxy cluster MACS J1206.2-0847. The apparently distorted shapes of distant galaxies in the background is caused by an invisible substance called dark matter, whose gravity bends and distorts their light rays. MACS 1206 has been observed as part of a new survey of galaxy clusters using Hubble.  |
| Posted: 12 Oct 2011 05:34 AM PDT The first steps have been taken towards rainwear which repairs itself. Not long ago "self-repairing materials" would have been considered science fiction. However, scientists are now working on a textile coating which automatically seals small holes and tears in the surface layer of waterproof work-wear.  |
