Scientists Find New Genetic Alterations in Lung Cancer
Scientists have developed the first noninvasive technique for detecting cells in the living human brain that give birth to new neurons and other types of brain cells. The new method may eventually lead to improved treatments and diagnostics for a host of brain-related disorders, including depression, Parkinson's disease and brain tumors.
Tracking Neural Progenitor Cells in the Human Brain
Researchers have detected dozens of genetic regions that are altered in lung cancer, the leading cause of cancer deaths worldwide. The findings provide new clues to the biology of lung cancer and will help shape future strategies for diagnosing and treating the disease.
Protein Key to Severity of Staph Infections
Scientists have discovered why some strains of the Staphylococcus aureus bacterium ("Staph") can be so dangerous. They hope to use the finding to advance development of new therapeutic treatments.

Lack of Sleep Disrupts Brain's Emotional Controls
Experience tells us that sleepless nights can lead to overwrought emotions. Now scientists have uncovered some of the first evidence of how this occurs. Their imaging studies show that lack of sleep can lead to greater activation of the brain's emotional centers and disrupt the brain circuits that tame emotional responses.
A Brain of Many Colors
Using a clever genetic trick to generate dozens of different colors, researchers have for the first time visualized hundreds of cells and their connections to each other in the brain.
Scientists Unveil Structure of Common Drug Target
More than 40 years after beta blockers were first used clinically, scientists have finally gotten a close-up look at the drugs' molecular target: the β2-adrenergic receptor. The breakthrough promises not only to speed the discovery of new and improved drugs, but to illuminate many aspects of human health and disease.
