| Posted: 09 Nov 2011 08:05 PM PST A team of Italian scientists has fired a laser beam into a hunk of glass to create what they believe is an optical analogue of the Hawking radiation that many physicists expect is emitted by black holes.  |
| New advances in the study of silicon structure Posted: 09 Nov 2011 04:36 PM PST Amorphous silicon is one of the key materials in the manufacturing of next-generation solar panels and flat-screen televisions. A recent study has revealed that the energy of amorphous silicon – the state in which it exhibits the greatest stability – is 50% lower than the value commonly accepted until now. According to the researchers, this information is important for understanding the structure of the material and improving its properties.  |
| Physicists chip away at mystery of antimatter imbalance Posted: 09 Nov 2011 01:13 PM PST Why there is stuff in the universe is one of the long-standing mysteries of cosmology. A team of researchers has just concluded a 10-year-long study of the fate of neutrons in an attempt to resolve the question, the most sensitive such measurement ever made. The universe, they concede, has managed to keep its secret for the time being, but they've succeeded in significantly narrowing the number of possible answers.  |
| Are electron tweezers possible? Apparently so Posted: 09 Nov 2011 01:13 PM PST A recent paper demonstrates that the beams produced by modern electron microscopes can be used not just to look at nanoscale objects, but to move them around, position them and perhaps even assemble them.  |
| Ancient lunar dynamo may explain magnetized moon rocks Posted: 09 Nov 2011 10:18 AM PST The presence of magnetized rocks on the surface of the moon, which has no global magnetic field, has been a mystery since the days of the Apollo program. Now a team of scientists has proposed a novel mechanism that could have generated a magnetic field on the moon early in its history.  |
| Chemists reveal the force within you: New method for visualizing mechanical forces on cell surface Posted: 09 Nov 2011 08:58 AM PST A new method for visualizing mechanical forces on the surface of a cell provides the first detailed view of those forces, as they occur in real-time. Emory chemists were able to measure something that's never been measured before: The force that one molecule applies to another molecule across the entire surface of a living cell, and as this cell moves and goes about its normal processes.  |
| Clear vision despite a heavy head: Model explains the choice of simple movements Posted: 09 Nov 2011 08:56 AM PST The brain likes stereotypes -- at least for movements. Simple actions are most often performed in the same manner. A mathematical model explains why this is the case and could be used to generate more natural robot movements and to adapt prosthetic movements.  |
| Weird world of water gets a little weirder Posted: 09 Nov 2011 08:15 AM PST Strange, stranger, strangest! To the weird nature of one of the simplest chemical compounds -- the stuff so familiar that even non-scientists know its chemical formula -- add another odd twist. Scientists are reporting that good old H2O, when chilled below the freezing point, can shift into a new type of liquid.  |
| Fundamental discovery casts enzymes in new light Posted: 09 Nov 2011 06:39 AM PST A tree outside an office window provided the inspiration for a discovery that may ultimately lead to drugs with fewer side effects, less expensive biofuels and more.  |
| Chemists develop compounds capable of forming heath-resistant, economic and biocompatible gels Posted: 09 Nov 2011 06:37 AM PST Eating a yogurt or a jelly, using a pharmaceutical or cosmetic cream or shampoo... are just some of the numerous everyday actions in which we use gels developed through a process of gelation. Researchers have now developed a new family of compounds that enables to develop gels more resistant to high temperatures with a higher level of biocompatibility and able to work with a variety of organic solvents, and all this with an easy synthesis, scalable and low cost. This family of compounds has significant applications in industries such as pharmaceuticals and cosmetics or food industry, among others.  |
| Posted: 27 Oct 2011 01:31 PM PDT Managing light to carry computer data, such as text, audio and video, is possible today with laser light beams that are guided along a fiber-optic cable. These waves consist of countless billions of photons, which carry information down the fiber across continents. A research team wants to refine the optical transmission of information by using a single photon, the fundamental building block of light that can allow unprecedented applications in optical information transfer.  |
