Friendly bacteria in humans may protect against HIV

...try, University of Illinois at Chicago. "If we can find its natural enemy, we can control the spread of HI...s," says Tao. "To block HIV, however, we needed to find bacteria that prefer the unusual sugar mannose and thus can capture it." To identify bacteria that ...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...ch is located on the mainland side of the gulf. To find out, the researchers analyzed a series of images from an orbiting NASA satellite called SeaWiFS, which is equipped with special light-sensitive instruments that can detect phytoplankton floating near the surface of the sea. "These instruments measur...

Measuring Enzymes At End Of Cancer Pathway Predicts Outcome Of Tarceva, Taxol

... therapy in other forms of cancer, Ueno says. "We find here that as long as CDK2 is suppressed, the drug works, so developing an accurate test for CDK2 activity would be a boon for delivering individualized therapy to patients," he says. Such a test, however, will require that patients be given the drug ...

Bevacizumab Combined With Chemotherapy Improves Progression-Free Survival for Patients With Advanced Breast Cancer

...istically significant. “This study is the first to find a benefit of anti-angiogenic therapy in patients with breast cancer and represents a major advance in the treatment of patients with metastatic disease," said Study Chair Kathy D. Miller, M.D., of the Indiana University Medical Center in Indianapolis...

Researchers make surprise discovery that some neurons can transmit three signals at once

... auditory information. "It will be interesting to find out whether abnormal hearing, such as partial deafness or hearing dominated by noise, which in humans can affect normal language development, would cause glutamate to still be released. Finding such an association would be intriguing, but for now thi...

The circadian clock: Understanding nature's timepiece

...ll. When someone shifts their schedule, we want to find a way to shift their body with them so they remain alert, working optimally and making the right decisions." Antle also hopes to experiment further with a technique that involves resetting the circadian clock by altering serotonin levels, the same n...

Rhesus monkeys can assess the visual perspective of others when competing for food

...s case, for example, rhesus monkeys were unable to find food under a hidden location when the human experimenter who hid the food preferentially looked at the hidden location. These results suggest that competition-like situations may bring out the primates' abilities more than experiments that don't invo...

Gene therapy cures inherited liver disease in rats

Researchers find new giant amphibian fossils in Africa

...paleontologist, and co-author, Hans Larsson. "This find is particularly interesting because the animals we found are not present anywhere else in the world at that time. These animals seemed to be restricted to this one region of Africa that had one of the driest climates on the planet. Animal communities...

Stanford gut check shows diversity of intestinal ecosystem

...ion about all known species. "We thought we would find new ones, but it was a bit surprising to see such a large percentage that had remained unidentified," said Eckburg. "Despite this large effort, we are still not approaching the point of complete coverage of the intestinal community in any one individ...

Too much water may be as dangerous as too little during long-distance athletic events

...hroughout. "All serious distance athletes should find out what their rate of fluid loss is and individualize their fluid intake prior to a distance event," Dr. Levine said. "It's also good to accept some mild dehydration during a long race. There are plenty of Web sites available now that show how to cu...

A New Species of Monkey is Discovered in Tanzania: The First in Africa for More Than 20 Years
