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.

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.

The areas stained blue are regions in the fruit fly where the spineless gene is expressed.” height=”211″ width=”150″ />Pretty fly – for a fruit fly. The areas stained blue are regions in the fruit fly where the spineless gene is expressed.A team of researchers that includes biologists from Washington University in St. Louis has discovered that a gene involved in the development and function of the fruit fly antenna also gives the organism its color vision. Claude Desplan, Ph.D., professor of biology at New York University, and his students made the discovery and provided the data. Ian Duncan, Washington University professor of biology, and his wife, research assistant Dianne Duncan, provided the Desplan laboratory fruit fly (Drosophila) clones and mutants and technical assistance that helped locate where the gene, called spineless, is expressed in the retina.

Successful strategies are innovative. They combine resources or businesses in unique or complex ways that other firms may fail to recognize. Yet research from the Olin School of Business at Washington University finds that the market tends to undervalue companies with complex or unique strategies. The reason: they receive less analyst coverage. More…

Current levels of defense spending represent less than 5 percent of the nation’s gross domestic product (GDP), says Murray Weidenbaum, the Mallinckrodt Distinguished University Professor at Washington University in St. Louis. He says that the cost of today’s war pales in comparison to military outlays of about 35 percent of GDP at the peak of World War II; 15 percent of GDP for the Korean War; 10 percent for Vietnam and 6 percent for the Gulf War.

David Kilper / WUSTL PhotoThreat of injunctions can be beneficial in cases like eBay and BlackBerry, says WUSTL expert F. Scott Kieff.The threat of an injunction to protect patented technology, as seen in eBay v. MercExchange, is what drives infringers and patentees to strike deals — sometimes on the steps of the courthouse — because shutting down the business would lose money for both sides, says F. Scott Kieff, J.D., an associate professor of law at Washington University in St. Louis. These deals, he points out, are what drive innovation. More…
