First biomarker for human sleepiness identified in fruit flies

...popular target for diagnostics. Saliva was also an attractive target for Shaw's lab because the brain areas that regulate sleep drive are known to send signals to the brain areas that regulate salivation. To start his search, Shaw subjected the flies to different kinds of sleep deprivation and used microarra...

Nanoparticle assembly enters the fast lane

...ano-objects. However, in order to really turn this attractive approach into nanotechnology, we have to understand the complexity of interaction in such hybrid systems." The synthetic DNA used in the laboratory is capped onto individual gold nanoparticles and customized to recognize and bind to complementary ...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

... and other fossil fuels." "Biofuels are not only attractive for their potential to cut reliance on oil imports but also their reduced environmental impact," said Dr. Gerald A. Tuskan, ORNL and DOE JGI researcher and lead author of the SCIENCE study. "Biofuels emit fewer pollutants than fossil fuels such as ...

Batfish to the rescue!

...are vulnerable because their large size makes them attractive to spear-fishers, while they depend as young fishes on coastal mangroves which are in decline in many areas. "Indeed, the resilience of inshore GBR reefs may be closely tied to the fate of mangroves and their suitability for batfish recruitment." ...

'Killer' B cells demonstrate evolutionary link between fish and mammal immune systems

...er vaccines may make the practice more financially attractive to fisherman and less destructive to fish populations." There is little doubt that, despite the behavioral differences, the fish B cells represent a less advanced version of mammalian B cells. Sunyer found the very cellular structures that medical...

Mother birds give a nutritional leg up to chicks with unattractive fathers

...the developmental process, into eggs sired by less attractive fathers. "For female birds, an important aspect of parental investment is the resources allocated to eggs," writes Dr. Kristen J. Navara (Auburn University and Ohio State University) and her coauthors. "The resources available to any female for rep...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

...n life, when a formerly favorite food becomes less attractive after we have over-indulged in that food. "Moment by moment, this low-level information processing in the brain helps us react to what we like or don't like," he says. "These neurons respond to a taste as pleasurable, or as not pleasurable." Bu...

Producing bio-ethanol from agricultural waste a step closer

...f great interest around the world. One of the most attractive alternatives is bio-ethanol - alcohol produced from agricultural crops. At present, bio-ethanol is only made from sugars derived from corncobs, sugar beets, grain and sugarcane, with the help of baker's yeast. A great number of by-products result fro...

Researchers attack tumor cells by exploiting dependency on sugar metabolism

...ific aspect of glucose metabolism may represent an attractive and potentially well-tolerated approach to interfering with tumor growth. Normal cells produce most of the ATP they need to power cellular functions through an oxygen-dependent process known as oxidative phosphorylation. In contrast, cancer cells c...

New roles for growth factors: Enticing nerve cells to muscles

... axons that sniff their way through a labyrinth of attractive and repulsive chemical cues that guide them to their target. While several recent studies discovered molecules that repel motor neuron axons from incorrect targets in the limb, scientists at the Salk Institute for Biological Studies have identified...

Sticky surfaces turn slippery with the flip of a molecular light switch

...from non-polar to polar, the material becomes less attractive to proteins that might stick to its surface, according to Belfort. Exposing the material to UV light is like flipping a molecular switch, causing sticky proteins to detach from the surface and wash away in the liquid, the researchers report. Not onl...
