| Scary driving? Put the brakes on using your brain power Posted: 28 Jul 2011 07:04 PM PDT Researchers have used drivers' brain signals, for the first time, to assist in braking, providing much quicker reaction times and a potential solution to the thousands of car accidents that are caused by human error.  |
| Posted: 28 Jul 2011 01:26 PM PDT Scientists have discovered a new relation among electric and magnetic fields and differences in temperature, which can result in swirling vortices of electrons and holes in semiconductor devices and emit sideways magnetic fields. Understanding the unusual new effect may lead to more efficient thermoelectric devices, which convert heat into electricity or electricity into heat.  |
| Posted: 28 Jul 2011 11:47 AM PDT Chemists have accomplished in the lab what until now was considered impossible: transform a family of compounds which are acids into bases. Their research shows it is possible to replace phosphorus ligands in catalysts with boron ligands. While phosphorus is toxic, boron is not. The research makes possible a vast array of chemical reactions -- such as those used in the pharmaceutical and biotechnology industries, manufacturing new materials and research academic institutions.  |
