| Lactating tsetse flies models for lactating mammals? Posted: 18 Apr 2012 01:23 PM PDT An unprecedented study of intra-uterine lactation in the tsetse fly reveals that an enzyme found in the fly's milk functions similarly in mammals, making the tsetse a potential model for lipid metabolism during mammalian lactation. Better yet, reduced levels of this enzyme led to poor health in offspring, leading the authors to suggest that targeting it could help decrease the tsetse population in Africa and so reduce the incidence of sleeping sickness. |
| Jellyfish on the rise in world's coastal ecosytems Posted: 18 Apr 2012 10:53 AM PDT Jellyfish are increasing in the majority of the world's coastal ecosystems, according to the first global study of jellyfish abundance. |
| New research could mean cellphones that can see through walls Posted: 18 Apr 2012 10:53 AM PDT Researchers have designed an imager chip that could turn mobile phones into devices that can see through walls, wood, plastics, paper and other solid objects. |
| How selective hearing works in the brain: 'Cocktail party effect' explained Posted: 18 Apr 2012 10:50 AM PDT The longstanding mystery of how selective hearing works -- how people can tune in to a single speaker while tuning out their crowded, noisy environs -- has just been solved. Psychologists have known for decades about the so-called "cocktail party effect," a name that evokes the Mad Men era in which it was coined. It is the remarkable human ability to focus on a single speaker in virtually any environment -- a classroom, sporting event or coffee bar -- even if that person's voice is seemingly drowned out by a jabbering crowd. |
| Where do the highest-energy cosmic rays come from? Probably not from gamma-ray bursts Posted: 18 Apr 2012 10:50 AM PDT Some rare cosmic rays pack an astonishing wallop, with energies prodigiously greater than particles in human-made accelerators like the Large Hadron Collider. Their sources are unknown, although scientists favor active galacti nuclei or gamma-ray bursts. If so, gamma-ray bursts should produce ultra-high-energy neutrinos, but scientists searching for these with IceCube, the giant neutrino telescope at the South Pole, have found exactly zero. The mystery deepens. |
| Can behavior be controlled by genes? The case of honeybee work assignments Posted: 18 Apr 2012 06:55 AM PDT Biologists have demonstrated that the division of labor among honeybees is correlated with the presence in their brains of tiny snippets of noncoding RNA, called micro-RNAs, or miRNAs, that suppress the expression of genes. |
| Green-glowing fish provides new insights into health impacts of pollution Posted: 18 Apr 2012 06:54 AM PDT Understanding the damage that pollution causes to both wildlife and human health is set to become much easier thanks to a new green-glowing zebrafish. The fish makes it easier than ever before to see where in the body environmental chemicals act and how they affect health. The fluorescent fish has shown that estrogenic chemicals, which are already linked to reproductive problems, impact on more parts of the body than previously thought. |
| First description of a triple DNA helix in vacuum Posted: 18 Apr 2012 06:53 AM PDT Scientists have managed for the first time to extract trustworthy structural information from a triple helix DNA in gas phase, that is to say in conditions in which DNA is practically in a vacuum. This research could bring the development of antigen therapy based on these DNA structures closer. |
| Hair regeneration from adult stem cells Posted: 18 Apr 2012 06:50 AM PDT Scientists have demonstrated "functional hair regeneration from adult stem cells." This is a substantial advance in the development of next-generation of "organ replacement regenerative therapies." |
