| Narrowest bridges of gold are also the strongest, study finds Posted: 13 Jul 2011 01:18 PM PDT At an atomic scale, the tiniest bridge of gold -- that made of a single atom -- is actually the strongest, according to new research.  |
| 25 Tesla, world-record 'split magnet' makes its debut Posted: 13 Jul 2011 10:16 AM PDT A custom-built, $2.5 million "split magnet" system with the potential to revolutionize scientific research in a variety of fields has made its debut at the National High Magnetic Field Laboratory at Florida State University.  |
| Evolved stars locked in fatalistic dance Posted: 13 Jul 2011 09:13 AM PDT White dwarfs are the burned-out cores of stars like our sun. Astronomers have discovered a pair of white dwarfs spiraling into one another at breakneck speeds. Today, these white dwarfs are so near they make a complete orbit in just 13 minutes, but they are gradually slipping closer together. About 900,000 years from now -- a blink of an eye in astronomical time -- they will merge and possibly explode as a supernova.  |
| Posted: 13 Jul 2011 09:13 AM PDT A novel application of carbon nanotubes shows promise as an innovative approach to storing solar energy for use whenever it's needed. Storing the sun's heat in chemical form -- rather than converting it to electricity or storing the heat itself in a heavily insulated container -- has significant advantages, since in principle the chemical material can be stored for long periods of time without losing any of its stored energy. The problem with that approach has been that until now the chemicals needed to perform this conversion and storage either degraded within a few cycles, or included the element ruthenium, which is rare and expensive.  |
| New method for making human-based gelatin Posted: 13 Jul 2011 07:19 AM PDT Scientists are reporting development of a new approach for producing large quantities of human-derived gelatin that could become a substitute for some of the 300,000 tons of animal-based gelatin produced annually for gelatin-type desserts, marshmallows, candy and innumerable other products.  |
| New electric concept car has excellent driving dynamics Posted: 13 Jul 2011 07:19 AM PDT Following months of preliminary work on computer simulations, the first completed prototype of the new electric concept car showed in its first driving tests that it possesses excellent driving properties -- not only in theory, but also in practice.  |
| Chemistry: Separation a thousand-fold faster may lead to new composite materials Posted: 13 Jul 2011 06:30 AM PDT Numerous industrial processes make use of blends. Researchers have studied how the external electric field affects the rate of component separation in blends composed of polymers and liquid crystals and those composed of various types of polymers. The observations gathered open interesting opportunities, e.g., for the development of new composite materials.  |
| Wind-turbine placement produces tenfold power increase, researchers say Posted: 13 Jul 2011 06:21 AM PDT The power output of wind farms can be increased at least tenfold simply by optimizing the placement of turbines on a given plot of land, say researchers conducting a unique field study at an experimental two-acre wind farm in northern Los Angeles County, California.  |
| Posted: 13 Jul 2011 06:21 AM PDT A new study combining data from the European Southern Observatory's Very Large Telescope and the European Space Agency's XMM-Newton X-ray space observatory has turned up a surprise. Most of the huge black holes in the centres of galaxies in the past 11 billion years were not turned on by mergers between galaxies, as had been previously thought.  |
