13-12-13 a molecule containing a noble gas has been discovered in space by a team including astronomers from cardiff university. the find was made using a cardiff-led instrument aboard europe's herschel space observatory. the molecule, argon（氩） hydride（...

13-09-30 one problem in developing more efficient organic led light bulbs and displays for tvs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or led. university of utah physicists believe...

13-08-01 virginia commonwealth university researchers have discovered, in theory, the possibility of creating large, hollow magnetic cage molecules that could one day be used in medicine as a drug delivery system to non-invasively treat tumors, and in other...

13-05-21 a new study of both computer-created and natural proteins suggests that the number of unique pockets -- sites where small molecule pharmaceutical compounds can bind to proteins -- is surprisingly small, meaning drug side effects may be impossible to...

13-04-08 a research team led by professor makoto fujita of the university of tokyo, japan, and complemented by academy professor kari rissanen of the university of jyvskyl, finland, has made a fundamental breakthrough in single-crystal x-ray analysis, the mo...

12-11-21 scientists at imperial college london have developed a system to quickly detect trace amounts（微量） of chemicals like pollutants, explosives or illegal drugs. the new system can pick out a single target molecule from 10,000 trillion water molecule...

12-04-25 one of the greatest mysterious in cellular biology has been given a new twist thanks to findings reported in science. researchers at the riken brain science institute show that prions（小蛋白粒） , proteins that transmit heritable information withou...

12-01-11 scientists at the university of leicester have opened up a whole new approach to the therapeutic intervention for a family of anti-cancer drug targets, thanks to a completely new and unexpected finding. professor schwabe and his colleagues, drs wats...

11-12-02 researchers at the university of pittsburgh have invented a new type of electronic switch that performs electronic logic functions within a single molecule. the incorporation of such single-molecule elements could enable smaller, faster, and more en...

11-01-21 using a new experimental test structure, biophysicists at jila have unraveled（解开，阐明） part of a 15-year mystery in the mechanics of dnajust how the molecule manages to suddenly extend to almost twice its normal length. the new test structure s...
