Research into toxins points to development of better medicines

Researchers have combined magnetic resonance spectroscopy with special protein synthesis procedures to uncover how potassium channels and toxins combine and change in structure. This work could make it possible to develop medications for high blood pressure and many other diseases connected to potassium channel failure .

Penn researchers discover gene that creates "second skeleton" bone disorder

Researchers at the University of Pennsylvania School of Medicine have located the "skeleton key," a gene that, when damaged, causes the body's skeletal muscles and soft connective tissue to undergo a metamorphosis into bone, progressively locking joints in place and rendering movement impossible.

Research sheds light on eating disorders, compulsive gambling and drug abuse

Researchers at Harvard Medical School (HMS) report in the April 23 issue of Nature that they have identified neurons that encode the values that subjects assign to different items. The activity of these neurons might facilitate the process of decision-making that occurs when someone chooses between different goods.

Link between expectancy, visual cues and the desire to smoke

In a study recently published in the journal Neuropsychopharmacology, researchers at the Montreal Neurological Institute (MNI) and the Department of Psychology at McGill University found that when people expect to smoke in the near future, external cues such as watching someone smoke affects their brain more than their level of craving or how long they have gone without a cigarette.
