Karen Elshout, Post-DispatchRobin Harris holds a blanket that belonged to her daughter, Kaitlyn, a teen whose depression led her to kill herself.The teenage brain may hold secrets which could help unlock some of the mysteries of mental illness. Adolescent brains undergo serious transitions and can become very volatile, making it sometimes difficult to distinguish between normal teenage behavior and serious mental illness. Some scientists believe several severe mental illnesses may even have roots in the developing teen brain.

Structure of the fatty acid receptor CD36French researchers recently reported that mice have a receptor in their tongues that can sense fat, and the presence of that receptor seems to drive the mice to crave fat in their diets. The research was based on work from scientists at the School of Medicine, where investigators previously had identified a protein receptor for fat and documented its function in recognizing and using fatty food.

Repair proteins (bright green areas) are inhibited from gathering at sites of DNA damage.To remain healthy, all cells must quickly mend any breaks that arise in their DNA strands. But cancer cells are particularly dependent on a process called homologous recombination to repair DNA and stay alive. Now researchers at the School of Medicine have identified a protein with a role in homologous recombination, and the discovery could be exploited as part of a two-pronged treatment strategy to kill cancer cells by eliminating their ability to repair DNA.
