Research suggests scientists should follow the body's lead to prevent HIV from taking rootFor 25 years, researchers have tried and failed to develop an HIV vaccine, primarily by focusing on a small number of engineered "super antibodies" to fend off the virus before it takes hold. So far, these magic bullet antibodies have proved impossible to produce in people. Now, in research to be published March 15 online by Nature, scientists at The Rockefeller University have laid out a new approach....

It takes weeks or months for the effect of most antidepressants to kick in, time that can feel like an eternity to those who need the drugs the most. But new research suggests that a protein called p11, previously shown to play a role in a person's susceptibility to depression, activates a serotonin receptor in the brain known for producing a rapid antidepressant response. If scientists could develop drugs to target this receptor, they might produce an effect in as little as two days. The...

A simple model explains how the locust brain encodes turbulent plumes of odors In the real world, odors don't happen one puff at a time. Animals move through, and subsequently distort, plumes of odor molecules that constantly drift, changing direction as the wind disperses them. Now, by exploring how animals smell odors under naturalistic conditions, Rockefeller University scientist Maria Neimark Geffen and her colleagues reveal that the brain encodes these swirling, and complex patterns of...

During its career, the potentially fatal hepatitis C virus has banked its success on a rather unusual strategy: its limitations. Its inability to infect animals other than humans and chimpanzees has severely hampered scientists in developing a useful small animal model for the disease. But now, in a breakthrough to be published in the January 29 advance online issue of Nature, Rockefeller University scientists have identified a protein that allows the virus to enter mouse cells, a finding...

A new neuroimaging study on stressed-out students suggests that male humans, like male rats, don't do their most agile thinking under stress. The findings, published this month in the Proceedings of the National Academy of Sciences, show that 20 male M.D. candidates in the middle of preparing for their board exams had a harder time shifting their attention from one task to another than other healthy young men who were not under the gun. Previous experiments had found that stressed rats...

New research from Rockefeller University suggests that pregnant women who consume high-fat diets may cause changes in their developing fetus' brain that could lead to obesity early in the child's life. The scientists conducted their research on rats, and found that those born to mothers fed on a high-fat diet had many more brain cells specialized to produce appetite-stimulating proteins. The researchers say their study may help explain the surging rates of obesity in recent...

Mothers who eat a high-fat diet during pregnancy may increase the likelihood of their child being overweight. Researchers at Rockefeller University in New York discovered that rats that were given a high-fat diet during pregnancy showed permanent changes in their offspring's brain that lead to overeating and obesity. This finding could provide a key step towards understanding the mechanisms of fetal programming and could explain the increased prevalence of child obesity over the last 30...

Nobel Prize winner George E. Palade, who helped give birth to the field of modern cell biology, has died at his home in Del Mar, Calif. He was 95. Palade died Tuesday of complications of Parkinson's disease, his wife, Marilyn Farquhar, said. Beginning in the 1940s Palade (pronounced pah-LAH-dee) began using electron microscopy and other techniques to discover tiny structures within cells and to help explain their functions, The New York Times said. "In cell biology he is clearly the most...

Scientists at Rockefeller University in New York have developed a mathematical model to help countries predict immigration patterns. The new formula is based on an extensive examination of the movement of people from 1960 to 2004 into the United States, Australia, Britain, Belgium, Canada, Denmark, Germany, Italy, the Netherlands, Spain and Sweden.   The researchers said the model can be applied to individual regions and countries, although they did not perform such calculations...

New research in mice suggests the powerful painkiller Oxycontin may be even more addictive for adolescents than it is for adults. Dr. Mary Jeanne Kreek and colleagues from the Rockefeller University in New York City report that fewer U.S. teens are using illegal drugs, but the abuse of prescription drugs, such as Oxycontin (generic oxycodone) and Vicodin (generic hydrocodone) is rising. The researchers say the brain undergoes dramatic changes in adolescence and there is evidence that abusing...
