| New optical tweezers trap specimens just a few nanometers across Posted: 04 Dec 2012 12:44 PM PST A microscale technique known as optical trapping uses beams of light as tweezers to hold and manipulate tiny particles. Researchers have found a new way to trap particles smaller than 10 nanometers -- and potentially down to just a few atoms in size -- which until now have escaped light's grasp. |
| Quantum thermodynamics: A better understanding of how atoms soak up their surroundings Posted: 04 Dec 2012 11:59 AM PST The best yet calculations of the effect of blackbody radiation on the wavefunction of ytterbium atoms, should help produce a better atomic clock. |
| Dance of quantum tornadoes: Quantum fluid trapped on top of semiconductor chip Posted: 04 Dec 2012 08:22 AM PST Tornado-like vortexes can be produced in bizarre fluids which are controlled by quantum mechanics, completely unlike normal liquids. New research demonstrates how massed ranks of these quantum twisters line up in rows, and paves the way for engineering quantum circuits and chips measuring motion ultra-precisely. |
| Fungus has cancer-fighting power, researchers find Posted: 04 Dec 2012 08:18 AM PST Arthrobotrys oligospora doesn't live a charmed life; it survives on a diet of roundworm. But a discovery could give the fungus's life more purpose -- as a cancer fighter. |
| Posted: 04 Dec 2012 05:13 AM PST If you think having your phone identify the nearest bus stop is cool, wait until it identifies your mood. Engineers may soon make that possible. Researchers have developed a new computer program that gauges human feelings through speech, with substantially greater accuracy than existing approaches. |
| Men with erection problems are three times more likely to have inflamed gums, study finds Posted: 04 Dec 2012 05:13 AM PST Men in their thirties who had inflamed gums caused by severe periodontal disease were three times more likely to suffer from erection problems, according to a new study. |
| Fitness for toad sperm: Secret is to mate frequently Posted: 04 Dec 2012 05:11 AM PST Fertility tests frequently reveal that males have problems with the quality of their sperm. The problems often relate to sperm senescence, which is a reduction in quality with age. Sperm senescence can arise either before or after the DNA in the sperm cells is produced by a process known as meiosis. So-called "pre-meiotic" senescence results from accumulated damage in the germline cells with increasing age and results in older males having sperm of lower quality. Post-meiotic senescence occurs after the sperm cells have been produced, either during storage of sperm by the male or after ejaculation and before they fertilize the eggs. |
