Researchers Make New Electronics -- With A Twist (November 21, 2008) -- Scientists have made electronics that can bend. They've made electronics that can stretch. And now, they've reached the ultimate goal -- electronics that can be subjected to any complex deformation, including twisting. Researchers have improved their so-called "pop-up" technology to create circuits that can be twisted. Such electronics could be used in places where flat, unbending electronics would fail, like on the human body. ... > full story

This technology could facilitate testing of anti-aging therapies as well as give physicians a means of tracking how individuals "withstand the tests of time." ... > full story
What Controls Critical 'Go-to' Enzyme: Findings May Hold Key To Better Treatments For Many Disorders (November 20, 2008) -- Scientists have gained new insights into regulation of one of the body's enzyme workhorses called calpains. As the cell's molecular overachievers, calpains function in many cellular processes, including the movement of cells in tissues, the death of damaged cells, insulin secretion, and brain cell and muscle function. The downside of this broad set of responsibilities is that defective or overactive calpains have been linked to an array of disorders, including a form of muscular dystrophy, Type 2 diabetes, gastric cancers, Alzheimer's and Parkinson's diseases, cataracts, and the death of both heart muscle in heart attacks and of brain tissue in stroke and traumatic brain injury. ... > full story
