WUSTL paleoanthropologist, colleagues develop artificial neural network model to predict location of fossil sites In 1991, a team led by Washington University in St. Louis paleoanthropologist Glenn Conroy, PhD, discovered the fossils of the first – and still the only – known pre-human ape ever found south of the equator in Africa after only 30 minutes of searching a limestone cave in Namibia. Traditionally, fossil-hunters often could only make educated guesses as to where...

Contact lenses have been around for decades, correcting vision problems and giving cosmetic or therapeutic aid, but what about using them as a mini-monitor to project text messages or short emails right in front of your eye? Sound like science fiction? Well, according to US researchers at Washington University, the idea of wearing computerized contact lenses is very close to reality. The futuristic technology has taken a step closer with the development of a prototype lens that could...

Nerve Cells Help Our Brain Make Sense Of Our Senses

[ Watch the Video ] The human brain is bombarded with a cacophony of information from the eyes, ears, nose, mouth and skin. Now a team of scientists at the University of Rochester, Washington University in St. Louis, and Baylor College of Medicine has unraveled how the brain manages to process those complex, rapidly changing, and often conflicting sensory signals to make sense of our world. The answer lies in a relatively simple computation performed by single nerve cells, an operation...

Scientists have developed a way to evaluate new treatments for some forms of attention deficit disorder. Working in mice, researchers at Washington University School of Medicine in St. Louis showed that they can use brain scans to quickly test whether drugs increase levels of a brain chemical known as dopamine. In a study published last year, the same group found that raising dopamine levels in mice alleviates attention deficits caused by neurofibromatosis type 1 (NF1), a condition that...

"Too busy," and "too complicated." These are the typical excuses one might expect when medical professionals are asked why they fail to use online error-reporting systems designed to improve patient safety and the quality of care. But Johns Hopkins investigators found instead that the most common reason among radiation oncologists was fear of getting into trouble and embarrassment. Investigators e-mailed an anonymous survey to physicians, nurses, radiation physicists and other radiation...

℠Sunk-cost´ mindset also keeps losers in the stock market Within hours this summer, 30 American troops died in a strike in Afghanistan and millions of American investors watched the Dow Jones Average shed an astonishing 634 points in one day. While it might be difficult to find similarities in the two events, social psychologists can detect a common theme: In each case, investments (money and human lives) were made, and those resources were painfully lost. The...

Study shows noninvasive, fast way to map heart's electrical activity in one heartbeat Just one second, one heartbeat. That's what is needed for a new, noninvasive functional imaging technology to record data for locating the source in the heart of a dangerous cardiac arrhythmia called ventricular tachycardia (VT). VT is an abnormal, fast beating of the heart, which, if ignored, can lead to ventricular fibrillation, which causes some 400,000 cases of sudden death yearly in the United...

Every day we make thousands of tiny predictions "” when the bus will arrive, who is knocking on the door, whether the dropped glass will break. Now, in one of the first studies of its kind, researchers at Washington University in St. Louis are beginning to unravel the process by which the brain makes these everyday prognostications. While this might sound like a boon to day traders, coaches and gypsy fortune tellers, people with early stages of neurological diseases such as...
