UCSD study of uncoordinated fruit flies provides molecular clues to hearing problems in humans

... help from the researchers they quickly die. "You literally have to hand-feed them, put food in their mouths, because they're so uncoordinated that they just can't function in any other way," said Richard G. Walker, a postdoctoral researcher at UCSD and the first author of the study. "It's a lethal mutation, ...

Reports of "weird life" almost stranger than fiction

...n Spear of the University of Colorado. "People are literally beginning to look under the rocks." D. radiodurans was living in swollen tins of irradiated meat when discovered in Oregon in the 1950s. Studies revealed a unique, almost bizarre, ability to repair numerous DNA double strand breaks--the most lethal ...

Advanced cell technology reports reversal

...describe how they used a new cloning technology to literally rewind the aging clock in cells. Virtually all types of body cells, except reproductive cells, contain this aging clock. It consists of a strand of DNA on the end of all chromosomes. These ends are called telomeres and every time a cell divides some ...

Success of introduced Argentine ants tied to reduced genetic variation

...ere territorial and aggressive toward one another, literally tearing one another apart whenever they came into contact.

It's still not clear how the dogs in New York became infected. Breitschwerdt's research and testing team is made up of more than a dozen NC State students...

Bio-X grant recipient explores link between molecular chaperones and serious diseases

...elp bigger ones fold and assemble. Some chaperones literally serve as escorts, guiding and twisting newborn proteins into their correct shape. ``No one expected that a cell would require special machinery for protein folding,`` says molecular biologist Judith Frydman, ``but what we are finding is that almost...

Insects caught in a nutrient-poor food web

...ing animals in lakes, where the animals seem to be literally swimming in nutrient-rich foods. The high quality of the aquatic diet gives diners the green light on rapid growth. Elser, an aquatic ecologist, teamed with eleven other experts in aquatic and terrestrial ecology to do the study. The main goal was to...

Conservation battle faces long odds in Brazilian Amazon

...s approach, nations and companies around the world literally pay for the rights to continue some of their development plans that would inject carbon into the atmosphere, so long as development plans elsewhere are shelved. The Brazilian Amazon offers an ideal site to sell such carbon credits, which might provid...

Women, particularly during menses, more at risk than men for developing prescription drug-induced heart problems

...s Torsades de Pointes (TdP), a French phrase which literally means "twisting of the points," referring to the characteristic appearance of an EKG during the rhythm abnormality. "The prolonged QT interval is really the first sign of trouble; it's an early warning sign that can be detected only with an EKG," acc...

Designer solvents promise revolutionary pollution solution

...at react with carbon dioxide and hydrogen sulfide, literally binding them into the solvent. Preliminary results indicate that heating contaminant-laden ionic liquids in a vacuum reverses the binding process, permitting the liquids to be reused, he says. Oxidation of organic compounds is one of the mos...

A worm is more like a human than previously thought

... few years ago allows worm genes to be knocked out literally overnight, thus speeding up gene studies enormously. ("Knockout" is the way that biologists study the function of genes by removing them one at a time, and examining the outcome.) The initial experiment that led to the discoveries described in t...

Researchers study muscle cell damage that occurs when astronauts return from space

...ch like a punctured tire is patched, muscles cells literally ripped apart by use after even a week of disuse appear to patch themselves in a matter of seconds, according to researchers at the Medical College of Georgia. "Nature has retained the economy of the patch," said Dr. Paul L. McNeil, cell biologist. ...

Neuroscientist studies brains of bizarre-looking mammals

...ory receptors that allow the hamster-sized mole to literally feel its way around its subterranean environment. Since coming to Vanderbilt, Catania has determined that the star-shaped nose is connected to the moles brain by some 100,000 nerve fibers, six times the number that connect the human hand and brain. B...

When Shewanella meets goethite: Evidence found of recognition between animate and inanimate objects

Co-investigators on the NSF grant are Lower at the University of Maryland and Virginia Tech researchers Susan Eriksson, associate professor of geological sciences; Maddy Schreiber, assistant pro...

Gene chips accurately diagnose four complex childhood cancers

...cellular genes are treated in such a way that they literally light up the gene dots on the chip. The luminescent pattern is then measured with a special type of microscope and the results fed into a computer for analysis. The NHGRI team applied this technique to the childhood cancers to see whether it could s...

Fatal attraction: Satellites to determine sea lions deaths

...rs - about 8 inches long and 2 inches wide - could literally be a lifesaver for the species, Horning believes. The device will serve as a sort of sea lion log book. It will record information on how the animal lived, areas it frequented, when it died and what it did before it died. When the animal has died, ...
