Computational Method Speeds Mapping of Cell Signaling Networks

...though the work was largely a "proof of principle" report designed to demonstrate the usefulness of their method, their studies also identified a previously unknown T-cell signaling interaction that connects two pathways. Prediction is the great strength of Bayesian network analysis--particularly in the po...

Buying Time Through Hibernation on Demand

... time." In the Science paper, Roth and colleagues report inducing a state of clinical torpor in mice for up to six hours before restoring their normal metabolic function and activity. They achieved this by placing the mice in a chamber filled with normal room air laced with 80 parts per million of hydroge...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

..."Our participants who measured very high on a self report questionnaire of romantic love also showed strong activity in a particular brain region ?results that dramatically increase our confidence that self-report questionnaires can actually measure brain activity." Aron also noted that the research answer...

Researchers uncover sequence of major rice pathogen

...ecular basis of fungal disease of plants. Here, we report the draft sequence of the M. grisea genome. Analysis of the gene set provides an insight into the adaptations required by a fungus to cause disease. The genome encodes a large and diverse set of secreted proteins, including those defined by unusual c...

Scientists identify genetic pathways essential to RNA interference

...which someday may help to fight human disease. The report will appear in the journal Science and is receiving early online release on the Science Express website at http://www.sciencexpress.org. "The gene activation produced by RNAi is exquisitely specific, which gives it enormous potential for therapeutic...

Researchers report new pro-inflammatory role for anti-inflammatory enzyme

...in the Journal of Biological Chemistry, scientists report that the predominantly anti-inflammatory enzyme, endothelial nitric oxide synthase, is also involved in nitric oxide production in response to infection. This discovery may eventually provide a new target to treat sepsis, which is caused by overprodu...

Potential Drug Target For Treating Cocaine Abuse Found

...ues at the National Institute on Drug Abuse (NIDA) report the results of experiments showing that mice treated with a substance similar to the drug benztropine did not show any of the typical hyperactive behavior when later injected with cocaine. This effect wore off after a day. Cocaine produces intense f...

Youth With HIV Take More Risks After New Meds Introduced

...or HIV were introduced in 1996, according to a new report in the American Journal of Health Behavior. A group of HIV-positive youth studied between 1999 and 2000 reported having more sexual partners, more unprotected sex and more drug use than HIV-positive youth studied between 1994 and 1996, say Marguerit...

Medical whistleblowers speak out

...and why they published Lenzer's account: "Lenzer's report will, we hope, spark discussion and debate about how American medicine - clinicians, researchers, regulatory agencies, and medical journals - can disentangle itself from the influence of the pharmaceutical industry." ...

A puzzle piece found in unraveling the wiring of the brain

...ng a gene that plays a key role in brain wiring. A report on their work appears today in the journal Neuron. "We were surprised to find an exocyst mutant having such specific defects," said Bellen, professor of molecular and human genetics at BCM. "The cell biological basis of brain wiring is largely unkno...

Plant Sacrifices Cells to Fight Invaders

...sity's Savithramma Dinesh-Kumar and his colleagues report finding a gene that normally propagates a "pro-survival" signal in plant tissue. Without that input, an alternate "pro-death" signal moves out of the infected areas and damages the rest of the plant. The group studied the plant-pathogen interactions...
