| Cylinder hides contents and makes them invisible to magnetic fields Posted: 22 Mar 2012 12:15 PM PDT Researchers have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using superconductor and ferromagnetic materials available on the market. |
| Liquid-like materials may pave way for new thermoelectric devices Posted: 22 Mar 2012 10:15 AM PDT In the continual quest for better thermoelectric materials -- which convert heat into electricity and vice versa -- researchers have identified a liquid-like compound whose properties give it the potential to be even more efficient than traditional thermoelectrics. |
| Geologists discover new class of landform -- on Mars Posted: 22 Mar 2012 10:13 AM PDT An odd, previously unseen landform could provide a window into the geological history of Mars, according to new research by geologists. They call the structures periodic bedrock ridges. |
| Posted: 22 Mar 2012 10:13 AM PDT An optical diode made with silicon technology can be used for quantum information. Researchers propose using ring resonators to construct a micro-optical diode. The technology is silicon-on-insulator, making it compatible with the CMOS (complementary metal-oxide-semiconductor) fabrication processes underlying today's computer circuits. |
| Runaway planets zoom at a fraction of light speed Posted: 22 Mar 2012 08:36 AM PDT Seven years ago, astronomers boggled when they found the first runaway star flying out of our galaxy at a speed of 1.5 million miles per hour. The discovery intrigued theorists, who wondered: if a star can get tossed outward at such an extreme velocity, could the same thing happen to planets? New research shows that the answer is yes. |
| New technique lets scientists peer within nanoparticles, see atomic structure in 3-D Posted: 22 Mar 2012 07:04 AM PDT Researchers are now able to peer deep within material science's tiniest structures to create three-dimensional images of individual atoms and their positions. The research presents a new method for directly measuring the atomic structure of nanomaterials. |
| Posted: 21 Mar 2012 12:25 PM PDT Researchers have invented Hall effect magnetic field sensors that are operable at high temperatures and harmful radiation conditions. The sensors will find applications in space craft and nuclear power stations. |
