Your mood at the time might determine whether or not you help this woman.Do you consider yourself a moral person? Most of us do. But what is it exactly that makes us moral beings? A philosopher at Washington University in St. Louis thinks that circumstance and mood often have an extraordinary impact on how people behave, no matter what kind of character they may appear to have. Or, in other words, seemingly Sweet Sally may turn into Selfish Sally if in a foul mood. More …

Fueled by the simplicity of red state-blue state election maps, some pundits have leaped to the conclusion that America is experiencing a landmark shift in traditional political allegiances, with poor, working-class voters leaving the Democratic Party to become “NASCAR Republicans” while wealthier voters join the ranks of an increasingly elite bunch of liberal, limousine-driving “Latte Democrats.” Not so, says the WUSTL co-author of a new study of how income influences state-by-state voting patterns.

Neurons (shown here in green) fire more frequently in mice lacking Kv4.2 potassium channels.Studying mice, pain researchers at the School of Medicine have identified key components in the pain cascade that may provide targets for more effective analgesic drugs with potentially fewer side effects. Scientists have identified a potassium channel that plays a crucial role in what scientists call pain plasticity, the ability of molecules in the spinal cord to amplify or diminish the response to a painful stimulus.

The Sam Fox School of Design & Visual Arts at Washington University in St. Louis will honor four outstanding architecture alumni at its 13th annual Distinguished Alumni Awards Dinner April 6. Recipients will be Soo K. Chan (BArch ’84), Eric Haesloop (BArch ’77), Sandra Ford Mendler (BArch ’81) and Jimmie E. Tucker (MArch ’81). In addition, Corinna Cotsen (MArch and MSCE ’83) will receive the 2006 Dean’s Medal for exceptional service while Brian Vitale (March ’95) will receive the Young Alumni Award.

Islets isolated from a rat pancreasDiabetes researchers hoping to enlist the help of a protein targeted by cancer therapies have gained an important new insight into how the protein, known as mTOR, works in the pancreas. Ironically, diabetes researchers want to promote the capability of mTOR that oncologists want to shut down: its ability to cause cells to reproduce by dividing into copies of themselves.

Unraveling the mysteries of the human brain, and the mind it gives rise to, is within the reach of modern science, suggests a forthcoming issue of the journal Neuroscience. The special issue explores how sophisticated working memory processes — from the firing of a single neuron to the activation of multiple brain regions — help shape our understanding of the world, says issue co-editor Grega Repovs, a visiting post-doctoral fellow at Washington University in St. Louis.

Illustration of a lung volume reduction surgeryIn many cases of advanced emphysema, reducing the size of the lungs surgically has been shown to improve both survival and quality of life. But some emphysema patients can’t tolerate this bilateral operation. Now a study conducted by researchers at Washington University School of Medicine in St. Louis and the University of Pennsylvania Health System has shown that unilateral, or one-sided, lung volume reduction surgery has significant benefits, offering help to those who are not candidates for the bilateral surgery.

Restricting calories may mean living longer.Can eating a low-calorie yet nutritionally balanced diet extend human life as it does in rodents? Preliminary research suggests it might, so researchers at Washington University School of Medicine in St. Louis are launching a long-term study to find out. More…

Islets isolated from a rat pancreasDiabetes researchers hoping to enlist the help of a protein targeted by cancer therapies have gained an important new insight into how the protein, known as mTOR, works in the pancreas. Ironically, diabetes researchers are hoping to promote the capability of mTOR that oncologists want to shut down: its ability to cause cells to reproduce by dividing into copies of themselves. That capacity can be deadly in tumors, but diabetes researchers want to use mTOR’s ability to make cells divide to maintain enough insulin-making beta cells in the pancreas to prevent diabetes. More…
