| Hubble views the star that changed the universe Posted: 23 May 2011 02:11 PM PDT Though the universe is filled with billions upon billions of stars, the discovery of a single variable star in 1923 altered the course of modern astronomy. And, at least one famous astronomer of the time lamented that the discovery had shattered his world view. The star goes by the inauspicious name of Hubble variable number one, or V1, and resides in the outer regions of the neighboring Andromeda galaxy, or M31.  |
| Particle trap paves way for personalized medicine Posted: 23 May 2011 12:23 PM PDT Researchers have trapped individual charged particles in an aqueous solution using a method called "Paul trapping," which uses oscillating electric fields to confine the particles to a space only nanometers in size. The technique paves the way for DNA trapping and sequencing, which would allow for diagnostic testing, therapies and treatments based on each patient's individual genetic makeup.  |
| Using microbes to generate electricity? Posted: 23 May 2011 12:23 PM PDT Using bacteria to generate energy is a significant step closer following a breakthrough discovery. Researchers now demonstrate for the first time the exact molecular structure of the proteins which enable bacterial cells to transfer electrical charge.  |
| Novel artificial material could facilitate wireless power Posted: 23 May 2011 09:42 AM PDT Electrical engineers have determined that unique artificial materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires.  |
| Just four percent of galaxies have neighbors like the Milky Way Posted: 23 May 2011 09:42 AM PDT How unique is the Milky Way? To find out, astrophysicists compared the Milky Way to similar galaxies and found that just four percent are like the galaxy Earth calls home.  |
| Once thought a rival phase, antiferromagnetism coexists with superconductivity Posted: 23 May 2011 09:13 AM PDT Using neutron scattering and scanning tunneling microscopy, an international team of researchers found that antiantiferromagnetism co-exists -- rather than exclusively competing -- with superconductivity, according to a new study. The findings add further evidence to the team's earlier discovery that spin excitations play a crucial role in superconductivity.  |
| Portable hydrogen reactor for fuel cells Posted: 23 May 2011 07:19 AM PDT Chemical engineering students have developed a portable microreactor that converts liquid fuels into hydrogen for fuel cell batteries.  |
| World record in ultra-rapid data transmission Posted: 23 May 2011 07:17 AM PDT Scientists in Germany have succeeded in encoding data at a rate of 26 terabits per second on a single laser beam, transmitting the data over a distance of 50 kilometers, and decoding the information successfully. This is the largest data volume ever transported on a laser beam. The process enables the transmission of 700 DVDs' worth of content in just one second.  |
| New device could reduce surgical scarring Posted: 23 May 2011 04:53 AM PDT Researchers have developed a special wound dressing that they report was able to significantly reduced scar tissue caused by incisions.  |
| High performance electric motorcycle developed Posted: 23 May 2011 04:50 AM PDT Engineers have developed a prototype of a high-performance electric motorcycle, which has recently participated in the first electric motorcycle world championship.  |
| Black holes spin faster and faster Posted: 23 May 2011 04:49 AM PDT Astronomers have found that the giant black holes in the center of galaxies are on average spinning faster than at any time in the history of the universe. Scientists made the new discovery by using radio, optical and X-ray data.  |
