| More omnivore dilemmas: Seasonal diet changes can cause reproductive stress in primates Posted: 28 Nov 2012 03:29 PM PST When seasonal changes affect food availability, omnivores like blue monkeys adapt by changing their diets, but such nutritional changes may impact female reproduction, according to new research. |
| Posted: 28 Nov 2012 11:39 AM PST A completely new method of manufacturing the smallest structures in electronics could make their manufacture thousands of times quicker, allowing for cheaper semiconductors. Instead of starting from a silicon wafer or other substrate, as is usual today, researchers have made it possible for the structures to grow from freely suspended nanoparticles of gold in a flowing gas. |
| Posted: 28 Nov 2012 11:39 AM PST Researchers have demonstrated silk-based implantable optics that offer significant improvement in tissue imaging while simultaneously enabling photo thermal therapy, administering drugs and monitoring drug delivery. The devices also lend themselves to a variety of other biomedical functions. Biodegradable and biocompatible, these tiny mirror-like devices dissolve harmlessly at predetermined rates and require no surgery to remove them. |
| Scientists sniff out the substances behind the aroma in the 'king of fruits' Posted: 28 Nov 2012 08:22 AM PST The latest effort to decipher the unique aroma signature of the durian -- revered as the "king of fruits" in southeast Asia but reviled elsewhere as the world's foulest smelling food -- has uncovered several new substances that contribute to the fragrance. |
| Hagfish slime as a model for tomorrow's natural fabrics Posted: 28 Nov 2012 08:22 AM PST Nylon, Kevlar and other synthetic fabrics: Step aside. If new scientific research pans out, people may be sporting shirts, blouses and other garments made from fibers modeled after those in the icky, super-strong slime from a creature called the hagfish. |
| Researchers synthesize new kind of silk fiber, and use music to fine-tune material's properties Posted: 28 Nov 2012 08:21 AM PST Researchers have synthesized a new kind of silk fiber -- and find that music can help fine-tune the material's properties. |
| Could astronauts use a 3-D printer to make parts from moon rocks? Posted: 28 Nov 2012 06:39 AM PST Imagine landing on the moon or Mars, putting rocks through a 3-D printer and making something useful – like a needed wrench or replacement part. "It sounds like science fiction, but now it's really possible,'' scientists say. |
| Biggest black hole blast discovered: Most powerful quasar outflow ever found Posted: 28 Nov 2012 06:37 AM PST Astronomers have discovered a quasar with the most energetic outflow ever seen, at least five times more powerful than any that have been observed to date. Quasars are extremely bright galactic centers powered by supermassive black holes. Many blast huge amounts of material out into their host galaxies, and these outflows play a key role in the evolution of galaxies. But, until now, observed quasar outflows weren't as powerful as predicted by theorists. |
| For some feathered dinosaurs, bigger not always better Posted: 28 Nov 2012 06:32 AM PST Researchers have started looking at why dinosaurs that abandoned meat in favor of vegetarian diets got so big, and their results may call conventional wisdom about plant-eaters and body size into question. |
| The hungry caterpillar: Beware your enemy's enemy's enemy Posted: 27 Nov 2012 04:03 PM PST When herbivores such as caterpillars feed, plants may "call for help" by emitting volatiles, which can help defend the plants. The volatiles recruit parasitoids that infect and kill the herbivores, to the benefit of the plant. However, such plant odors can also be detected by other organisms. A new study shows how secondary parasitoids can use these signals to identify infected caterpillars, and duly infect the primary parasitoid, to the detriment of the original plant. |
| Drought affects Mediterranean truffle harvest Posted: 27 Nov 2012 06:41 AM PST An international research team has for the first time linked a continuous decline of the Périgord truffle with long-term Mediterranean summer drying. |
