Vampire bats keep out of trouble by running

...rom the small cuts they make. However, running may help them avoid being stepped on, Riskin suggests. More likely, the researchers say, the ability to run evolved long ago, when vampire bats had to prey on faster South American athletes such as the agouti, a rodent about the size of a hare, which might wa...

Multiple Campylobacter Genomes Sequenced

...rial virulence or fitness, so their presence could help to explain the different biological behaviors of these strains. There are also major variations in the genes responsible for synthesis of molecules that are important for the interaction of Campylobacter with the environment. Such differences could u...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...ors are working together," Selvin said. "This will help us further understand these marvelous little machines." ...

Surprising findings reported about iron overload

...dies," said Acton. "Our findings in non-Caucasians help everyone understand the prevalence of these conditions in other racial/ethnic groups." He added that many white Alabamians have Celtic origins, with some counties reporting Irish ancestry in 17 percent of the population. "The hemochromatosis C282Y m...

Gene Signatures Predict Interferon Response For Multiple Sclerosis Patients

...r patient is likely to respond to interferon would help doctors decide how close to monitor the patient or even whether to consider alternative treatments. In a new study, Sergio Baranzini et al. describe a computational model that can predict a patient's therapeutic response to interferon based on their ...

NASA links nanobacteria to kidney stones and other diseases

...testing for the presence of NB in human bodies can help reduce the risk for kidney stone formation in astronauts and would also be of benefit to the nearly one million Americans who are treated for kidney stones each year. ...

Live fast, die young true for forests too

... the journal Ecology Letters. This discovery could help scientists predict how forests will respond to ongoing and future environmental changes. "One implication of this fast turnover rate is that the world¹s most productive forests may be those likely to respond most quickly to such things as climatic c...

PET/MRI scans may help unravel mechanisms of prenatal drug damage

...etween a mother and her fetus during pregnancy may help us unravel the mechanisms of the drug's damaging effects on unborn children," said SNM member Helene Benveniste, M.D., Ph.D., chair of Brookhaven's medical department in Upton, N.Y., and lead author of the paper, "Maternal and Fetal 11C-Cocaine Uptak...

Camera Traps Catch Eye of the Tiger

... Sumatra. WWF scientists are using camera traps to help conduct presence/absence surveys that will provide...umatra's lowland rainforest. The cameras will also help provide a density estimate of tigers in various habitat types and determine whether there are adequa...

Researchers discover molecular mechanism that desensitizes us to cold

...s. "This finding provides critical information to help us understand how we sense heat and cold and from that to expand our understanding of temperature regulation," said Dr. Logothetis. "Additionally, because the region of this receptor that interacts with PIP2 is found in many similar membrane proteins...

Chemists identify immune system mechanism for methamphetamine binges

Viral protein influences key cell-signaling pathway

...the cells that HTLV-1 infects. The findings might help scientists better understand how HTLV-1 maintains its lifelong infection and how the normal immune cells that "remember" a vaccination or an infection can survive for years or even decades. "The p300 protein is an important central regulator of gene...

NIH Calls on Scientists to Speed Public Release of Research Publications

... monitor scientific productivity, and, ultimately, help set research priorities; and 3. making published results of NIH-funded research more readily accessible to the public, health care providers, educators, and scientists. Beginning May 2, 2005, the policy requests that NIH-funded scientists submit...

Molecule that usually protects infection-fighting cells may cause plaque deposits inside arteries

...acrophages, which circulate in the bloodstream and help the body fend off infection and foreign substances. The AIM-protected macrophages go on to encourage buildup of fats on the interior walls of arteries, according to Dr. Toru Miyazaki, senior author of a study that appears in the March issue of the jo...

Iron exporter revealed that may explain common human disorder

...ein is critical in the cellular export of iron may help to explain human hemochromatosis, researchers report in the March issue of Cell Metabolism. Hemochromatosis--which affects one in every 200 to 300 people in Western populations --causes tissues of the body to become overloaded with iron. Left untrea...

Nanoscale Diagnostic Sets Sights on Alzheimer's

This is particularly important for diseases like Alzheimer's where a reliable diagnostic tool is lacking and early intervention could have a significant impact on the lives of patients and the...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...ng polluted soil available. "Phytoremediation can help clean up the selenium, but the thing that's holding people up from using plants more widely is that, by and large, they work slowly," said Terry. "So what we want to do is take a plant like Indian mustard, because it can grow quickly -- up to six to ...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...etely different infectious capabilities. With the help of atomic-level microscopic observation of prions in humans, mice, and hamsters, Jones and Surewicz discovered that it is the specific shape of the amyloid fibrils, and not the amino acid sequences, that may allow prions from one species to infect an...
