Channel protein converts vibrations to electrical signal

... that such a molecule must exist in the tiny cilia extending from receptor cells in the inner ear. Now, researchers led by Howard Hughes Medical Institute investigator David P. Corey, who is at Harvard Medical School, have several lines of evidence that, in vertebrates, this mechanosensitive channel is formed ...

Time-lapse movies show brain cells move like a two-stroke engine

... a "step." First it stretches out along the fiber, extending what scientists call a leading process in the direction it wants to move. About three minutes later the cell body catches up. "It's almost like a little inchworm in the way it moves," says Hatten, whose time-lapse movies first revealed this motion i...

NHGRI seeks next generation of sequencing technologies

New DNA repair enzyme makes mistakes to save lives of cells

...nd base next to the first one it inserted, thereby extending the chain as if all is normal. "POL-Q's two-step actions of insertion and extension, essentially the work that would be performed by two enzymes, are the most efficient of any known DNA polymerase. While a mispaired base may in turn result in a muta...

Studies in Royal Society journals include stress in birds and depletion of medieval fish stocks

...gative effects? Evolutionary theory predicts that extending lifespan will lead to reduced fitness. However, some mutants of the nematode Caenorhabditis elegans have a doubled lifespan without obvious side effects on development and fertility. We made such long-lived worms directly compete with normal worms ...

Dwarf mistletoe reveals its sexual secrets

...brations, fertility and kissing is an ancient one, extending back into pre-Christian Europe. The European mistletoe parasitizes apple and oak trees and thus in winter stands out in brilliant green against its leafless hosts. This evergreen nature, and the fact that the plant seems to emerge seedless from bird ...

MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

... "Dr. Lok has succeeded in adapting and creatively extending earlier developed techniques for stochastically simulating chemical reactions so that they can be used to study real cellular systems, where the huge numbers of potential species and reaction channels makes things very difficult." Computer simulation...

Anti-seizure drugs slow aging in worms

...e drug trimethadione having the largest effect and extending the worms' lives by 47 percent. The group then sought to uncover the underlying mechanism for the effect of the anticonvulsants. It was apparent that the drugs did not mimic the anti-aging effects of caloric restriction, because the worms had abundan...

UI researchers advance understanding of sexual evolution

UCSD discovery may help extend life of natural pesticide

...ss the molecule, from developing resistance to Bt, extending the life of this natural pesticide. The study, published February 11 in the journal Science, details the structure of a molecule to which Bt attaches, or "binds," in the lining of the intestines of insects and roundworms. The molecule is a glycolipi...

Intervention cuts nerve damage, boosts life span

... "We've identified a new point of intervention for extending life span by adjusting the amount of oxidative damage to nerve cells," said Stephen Helfand of the University of Connecticut Health Center in Farmington. Oxidative damage by free radicals is thought to be one of the primary forces driving the process...

Secrets of the cilia: Kidney disease and blindness share common genetic defect

... the kidneys' primary cilia hair-like projections extending from the surface of cells lining the kidney tubules. "When bent by the flow of urine, primary cilia send signals that influence key cellular functions," Hildebrandt says. "Mutations in NPHP genes prevent cilia from functioning properly, causing dama...

Gray wolves maintain the food chain in winter

... potential to provide a safety net for scavengers, extending the time they need to adapt to a changing environment. Thanks to a rebounding wolf population, field researchers can measure the magnitude of this predicted buffer effect. The models described here can guide their efforts and help species adjust to m...

UF researcher: Ideas about fossil horses undergo evolution in thinking

Researchers reveal the infectious impact of salmon farms on wild salmon

... lice levels exceeded what we would find normally, extending for 30 km even though the farm is only about 0.2 km long," says John Volpe, the third coauthor from the University of Victoria. "Conservatively this means that the parasite footprint of the farm is 150 times larger than the farm itself." Sea lice ca...
