| Posted: 02 Jan 2013 01:18 PM PST Almost all computer chips use two types of transistors: one called p-type, for positive, and one called n-type, for negative. Improving the performance of the chip as a whole requires parallel improvements in both types. Researchers have presented a p-type transistor with the highest "carrier mobility" yet measured. By that standard, the device is twice as fast as previous experimental p-type transistors and almost four times as fast as the best commercial p-type transistors. |
| How young star and planets grow simultaneously Posted: 02 Jan 2013 11:03 AM PST The ALMA telescope gives astronomers their first glimpse of a fascinating stage of star formation and helps resolve a mystery about how young planets and their infant star can both grow at the same time. |
| Galactic geysers fueled by star stuff Posted: 02 Jan 2013 11:01 AM PST Enormous outflows of charged particles from the center of our galaxy, stretching more than halfway across the sky and moving at supersonic speeds, have been detected and mapped with CSIRO's 64-m Parkes radio telescope. |
| Quadrantids create year's first meteor shower Posted: 02 Jan 2013 09:40 AM PST A little-known meteor shower named after an extinct constellation, the Quadrantids will present an excellent chance for hardy souls to start the year off with some late-night meteor watching. Peaking in the wee morning hours of Jan. 3, the Quadrantids have a maximum rate of about 80 per hour, varying between 60-200. Unfortunately, light from a waning gibbous moon will wash out many Quadrantids, cutting down on the number of meteors seen by skywatchers. |
| Secure communication technology can conquer lack of trust Posted: 02 Jan 2013 08:55 AM PST Many scenarios in business and communication require that two parties share information without either being sure if they can trust the other. Examples include secure auctions and identification at ATM machines. Exploiting the strange properties of the quantum world could be the answer to dealing with such distrust. |
| Optical strontium clock to become much more accurate Posted: 02 Jan 2013 07:49 AM PST Scientists have measured the influence of the ambient temperature on strontium atoms for the first time – measurement uncertainty has been reduced by one order of magnitude. |
| Posted: 02 Jan 2013 05:35 AM PST With its 2160 liters of liquid helium about to run out, the Herschel Space Observatory will, by the end of March, become just another piece of space junk. The astronomer who leads one of the telescope's largest surveys, explains how this space facility has advanced our understanding of star and galaxy formation. |
| Magnetic forces without magnets: Physicist calculates field strengths in the early universe Posted: 02 Jan 2013 05:35 AM PST Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has now been researched. A theoretical physicist describes a new mechanism for the magnetization of the universe even before the emergence of the first stars. |
