Elusive HIV shape change revealed; Key clue to how virus infects cells
Structural biologists at Children's Hospital Boston and Harvard Medical School have shown how a key part of the human immunodeficiency virus (HIV) changes shape, triggering other changes that allow the AIDS virus to enter and infect cells. Their findings, published in the Feb. 24 issue of the journal Nature, offer clues that will help guide vaccine and treatment approaches. Researchers led...Research on Worms Yields Clues on Aging
Humanityhas been looking for a "Fontaine de Jouvence" forever; a way to slow orstop aging. While its still nowhere to be found, we are makingprogress; in worms. Researchers found that an epilepsy drug used inhumans had the unexpected effect of prolonging the life span of C.Elegans: A class of anti-seizure medications slows the rate of aging inroundwo...New Clues Add 40,000 Years to Age of Human Species
Nearly 40 years after an historic anthropology expedition to Ethiopia's Lake Turkana basin, researchers have uncovered evidence suggesting human bones found at that time are roughly 195,000 years old. The researchers believe the findings may bolster the “Out-of-Africa?hypothesis that suggests we all trace to an ancient line that first evolved in Africa and then displaced other hominids as recent...Insight into DNA's 'weakest links' may yield clues to cancer biology
The chromosomes of mammals, including humans, contain regions that are particularly prone to breaking under conditions of stress and in cancer. Now, new research by geneticists at Duke University Medical Center finds that yeast cells also contain such weak links in DNA and begins to reveal the molecular characteristics of these links that might help to explain them. The findings, publishe...High-powered gene profiles provide clues to genes involved in common form of lung cancer
Using technology that makes it possible to zoom in on smaller sections of cell chromosomes than ever before, researchers at Dana-Farber Cancer Institute have identified nearly 100 chromosome regions where genes are either over-copied or missing in non-small cell lung cancer. The findings provide new clues about the location of genes potentially involved in the most common type of lung cancer –?an...Call centers and customer service: The good, the bad, and the clueless

Amputations continue to be a major complication of diabetes, despite the fact most are preventable. About one //half of all amputations are currently performed among the diabetic population. Researchers studied changes in the tiny blood vessels in the retinas of about 900 diabetic patients who had been diagnosed with the disease before age 30. All were followed for 20 years to assess ho...New clues about immune system from leprosy microbes
Scientists from UCLA and Harvard School of Medicine have successfully discovered how the body’s immune system// fights in limiting the control of infections like leprosy in some cases but not in others. The research says that the body’s initial immune system often fights with the infections in the initial stages and sometimes succeeds in controlling them. Only when they are unable to c...New clues to maternal aggressive behavior
Maternal aggressive and protective behavior is linked to the hormone oxytocin// (OT), and may affect the maternal instincts of animals and women in the same manner. The hormone is released from the neurohypophyseal terminals into the bloodstream as well as in the brain into the supraoptic nucleus (SON) and paraventricular nucleus (PVN), where it makes and impact on the behavior. The re...
