Brain switch provides clues to drug addiction

In the quest to find the biological route of drug addiction, research at Cambridge University, UK, is revealing what makes some people more vulnerable than others. Speaking at Europe's major neuroscience conference in Geneva, Professor Barry Everitt described what they now believe causes the switch from occasional, 'recreational' use to a compulsive habit.

New method to evaluate variations identified in breast cancer susceptibility genes

Using mouse embryonic stem cells, researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, have developed a new method to evaluate which mutations, or changes, in a gene known to increase breast cancer susceptibility, may lead to cancer. The new test, called a functional assay, is more comprehensive and reliable than most current methods.

WHO, Stop TB Partnership, UNITAID announce new tuberculosis test that quickly diagnoses MDR-TB

The World Health Organization, Stop TB Partnership, UNITAID and the Foundation for Innovative New Diagnostics on Monday announced a joint project to distribute a new diagnostic test for multi-drug resistant tuberculosis that can produce results in two days instead of the standard two or three months, the New York Times reports. Difficulty in identifying MDR-TB has been a "major obstacle" in controlling TB because many patients die or spread the disease while waiting for test results, the Times reports.
