Speak up: Louder neurons form more connections

... space,?Hua said. Hua gave those losing neurons a fighting chance through another molecular twist. She managed to silence some neurons near the green, quietly-firing cells. When she did that, the green cells were able to compete successfully and formed longer, more complex arbors. Although this work specifi...

Fat's fate depends on its source

... metabolism, offering an alternative mechanism for fighting chronic diseases, including obesity, diabetes, and heart disease, Semenkovich said. The researchers inactivated fatty-acid synthase, an enzyme that generates new fat from carbohydrates, in the livers of mice. When fed a diet completely lacking fat, ...

Scientists discover global pattern of big fish diversity in open oceans

... York in the United Kingdom. "Conservationists are fighting to place some areas off limits to fishing. This study provides welcome advice on the best places to put them." Some have doubted that marine reserves on the high seas would work because the big fish travel such great distances, but the new Science p...

Genome study of beneficial microbe may help boost plant health

... boost the effectiveness of beneficial microbes in fighting plant diseases. "This genomic sequence reveals previously unknown traits of P. fluorescens that increase its potential for biological control," says Loper. She is a plant pathologist with USDA's Agricultural Research Service (ARS) and is based at Or...

Cancer drug slows poxvirus in mice

...w being planned, Dr. Kalman says. "The approach of fighting disease by targeting drugs to cellular molecules rather than to disease agents themselves may be applicable to a wide variety of pathogenic microorganisms," he says. Routine vaccinations for smallpox ended in this country in the early 1970s, and the...

New vaccine means bye-bye to bacteria in the lung

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...ersity of Wisconsin have demonstrated a new way of fighting antibiotic resistance: by stopping evolution. In the June issue of the open-access journal PloS Biology, the team describes how a protein called LexA in the bacterium Escherichia coli promotes mutations and helps the pathogen evolve resistance to an...

Secret of smallpox's success may lead to bioterror cure

...y stages, but he may also have a powerful tool for fighting a host of other viral pathogens, including HIV. J... There is something going on here! I need to start fighting a virus infection!' and so it fights the mutant virus and a normal pathogenic virus as well." The g...

Plant Sacrifices Cells to Fight Invaders

... responses exhibited by animal cells when they are fighting a disease-causing agent. In fact, PCD is a well-researched, yet still puzzling phenomenon that has been described in virtually all cell types, both plant and animal. PCD plays a critical role in many biological processes including immune system func...

MUHC scientists describe genetic resistance to rampant virus

...h suggests there are many different mechanisms for fighting viruses; in the future we expect to discover additional resistant genotypes." CMV infects most of the world's organisms, including upwards of 80% of the human population. Although healthy people suffer only mild symptoms, infection can trigger fatal...

Defenseless plants arm themselves with metals

NYU study reveals how brain's immune system fights viral encephalitis

... cells in the brain. "There is no magic bullet in fighting viral infections in neurons," said NYU Biology Professor Carol Shoshkes Reiss, the study's senior author. "However, these findings show the redundancy of the immune system--when one response fails to fight infection, others step in." The study was a...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...war is occurring," Selvin said. "If the dynein was fighting the kinesin, we would expect to see a lot of smaller steps as well." The researchers also noted that faster movements occurred with the same step size, but with greater rapidity. When measured outside the cell, kinesin moved about 0.5 microns per se...

Towards precise classification of cancers based on robust gene functional expression profiles

...his particular protein is a promising approach for fighting diabetes, they say. "The MIF gene may be regulating other genes involved in type 1 diabetes," says Al-Abed. "We don't know yet, but we're looking into this." Besides drug intervention, the new finding could lead to gene therapy to prevent the diseas...
