Nicotine rush hinges on sugar in neurons

... (water repellent) matter that helps the structure hold its shape, Chen said. The water molecule may enable the receptor to alter its shape in counterbalance to the bending hinge, said Chen, who explained, “Think of it as a lubricant.” Previously studied “homologs” of nAChR – proteins that share its s...

Cells re-energize to come back from the brink of death

...er plants to supply the cell with energy, but also hold the keys to the cells’ life and death. The process by which the membranes develop holes—mitochondrial outer membrane permeability (MOMP)—is often the “point of no return” for self-destruction, said Douglas Green, Ph.D., chair of the St. Jude Im...

Soils offer new hope as carbon sink

...rposes. "We are hoping the technology will take hold and pyrolysis plants will be built where there is a steady stream of green or other biomass waste providing clean energy that is carbon negative," Dr Van Zwieten said. "But until pyrolysis plants are up and running, the availability of agrichar for ...

Discovery in orange cauliflower may lead to more nutritious crops

...issue of The Plant Cell -- allows the vegetable to hold more beta-carotene, which causes the orange color and is a precursor to the essential nutrient vitamin A. While cauliflower and many staple crops have the ability to synthesize beta-carotene, they are limited partially because they lack a "metabolic ...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...ether with the recently announced clinical trials, hold great promise." Mutations in LCA5 are relatively rare. As it is a recessive gene, a child would need to be carrying two copies of the gene to develop LCA, one from each parent. However, the disorder is more common within populations where marriage...

...region as part of a 2005 peace agreement, and will hold a referendum on independence in 2011. “I have never seen wildlife like that, in such numbers, not even when flying over the mass migrations of the Serengeti,” said Fay. “This could represent the biggest migration of large mammals on earth.” Fay,...

Surprising origin of cell's internal highways

...at the cell uses to move things around in order to hold its shape and divide, originated from a tiny structure near the nucleus, called the centrosome. Now, researchers at Vanderbilt University Medical Center reveal a surprising new origin for these cellular "highways." In the June issue of Developmenta...

Antarctic icebergs -- Hotspots of ocean life

...ytoplankton, krill, and fish below. The icebergs hold trapped terrestrial material, which they release far out at sea as they melt. The researchers discovered that this process produces a “halo effect” with significantly increased phytoplankton, krill and seabirds out to a radius of more than two miles ...

'Smart' mice teach scientists about learning process, brain disorders

...technology, we also found biochemical targets that hold promise for future treatments of a variety of cognitive disorders," he said. The researchers also recorded nerve-cell firings in the hippocampus, an area of the brain associated with learning. Hippocampus slices from the knock-out mice responded ...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...entially deadly H5N1 strain of avian influenza may hold the key to future treatments for the virus, according to an international team of researchers. In a study published today in the open access journal PLoS Medicine, the researchers have shown how specific antibodies taken from avian flu survivors in V...

Scientists: As rainfall changes, tropical plants may acclimate

... plant distribution and growth, such as those that hold sway over pollinators, insect predators or invasive plants. "These plants should be able to do OK in terms of their nitrogen nutrition, even with the climate changing," said Ted Schuur, a UF assistant professor of ecology and one of four authors o...

Students invent protective pouch to enhance cell therapy

...ted cells between the stents, where the mesh would hold them in place. The tiny openings in the mesh, each about 250 microns in diameter, would allow blood to pass through to nourish the cells and disperse helpful proteins. But the openings are too small to allow the microcapsules to escape. In lab te...

Tissue engineered scaffolding allows reproduction of cartilage tissue

Scientists have recognized for years that many types of bacteria and other microorganisms live in the human gut to the advantage of both the microbes and their human hosts. The results from the Virgin lab are among the first t...

Decoding protein structures helps illuminate cause of diabetes

...ps in between remain somewhat of a mystery and may hold clues to what drives the transition, says UW-Madison chemistry professor Martin Zanni, who led the new study. In trying to understand diabetes, "people have been looking at the fibers, but they should be looking at their formation," he says. "Som...

Executable biology -- Computer science sheds light on animal development

...t been described before. These kinds of models hold great promise for future exploration of a variety of biological systems, explains lead EPFL researcher and biologist Dr. Jasmin Fisher. "Once a robust model has been built of a particular system, it can be used to get a global, dynamic picture of how...

City ants take the heat

"We don't know whether this pattern will hold up for other species or other cities, but people should certainly be looking," said Angilletta, an Associate Professor of Ecology and Organismal Biology. "Ultimately, this research could help us to understand how species will respond to global climat...

Natural antibiotics yield secrets to atom-level imaging technique

Frog skin and human lungs hold secrets to developing new antibiotics, and a technique called solid-state NMR spectroscopy is a key to unlocking those secrets. That's the view of University of Michigan researcher Ayyalusamy Ramamoorthy, who will discuss his group's progress towar...
