| Meteorite discovery spurs hunt for more pieces Posted: 12 May 2012 07:10 AM PDT Meteorite fragments were recently scattered around Sutter's Mill in California, the same region where the first nugget of gold was found that sparked the Gold Rush in 1848. Scientists believe the meteorites may hold answers to unsolved mysteries about our solar system and the origins of molecules necessary for life. When the Gold Rush began, people headed to California seeking their fortune. Now, with this meteorite hunt, people once again have flocked to this area to search for scientific treasures.  |
| Posted: 10 May 2012 06:59 AM PDT The superbugs have met their match. It comes in the form of a coating which has a magnetic-like feature that attracts bacteria and kills them without the need for traditional antibiotics.  |
| Hard drives: A bit of progress Posted: 10 May 2012 06:56 AM PDT A modified approach to fabrication of magnetic memory elements may lead to a new generation of stable, ultra-high-capacity hard drives.  |
| Nanoparticle synthesis: Joined at the hip Posted: 10 May 2012 06:56 AM PDT Hybrid 'Janus' nanoparticles made from gold and titania have high catalytic activity and extraordinary durability.  |
| Posted: 10 May 2012 06:56 AM PDT A quiet revolution is taking place in the fields of biology and chemistry. Microfluidic devices, which allow fluid manipulation in micro-scale channels, are slowly but surely finding their place on the lab bench. A new microfluidic device can operate as a mixer or a valve, improving the efficiency of micro-scale laboratory apparatus.  |
| Molecular container gives drug dropouts a second chance Posted: 08 May 2012 12:21 PM PDT Chemists have designed a molecular container that can hold drug molecules and increase their solubility, in one case up to nearly 3,000 times.  |
| Posted: 08 May 2012 06:43 AM PDT Physicists have traced the double ionization of argon atoms on attosecond time scales. When an intense laser pulse interacts with an atom it generates agitation on the micro scale. The most likely outcome of this interaction is single ionization, where one electron is ejected from the atom. From time to time, however, two electrons can be removed from the atom, resulting in the more complex process of double ionization. The detailed course of this process on attosecond time scales (an attosecond is a billionth of a billionth of a second) has now been observed.  |
