Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass those limitations, but the components of such computers require semiconductors that can emit light.
According to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania, pre-operatively identifying patients with certain comorbid risk factors that may increase their chance of being admitted to the ICU following total hip replacement surgery results in fewer deaths, post-surgery complications, and unplann
Research has long shown the negative effects cigarette smoking has on cardiovascular health.
Early diagnosis is critical in treating Lyme disease. However, nearly one quarter of Lyme disease patients are initially misdiagnosed because currently available serological tests have poor sensitivity and specificity during the early stages of infection.
A psychological experiment known as “the marshmallow test” has captured the public’s imagination as a marker of self control and even as a predictor of future success. This test shows how well children can delay gratification, a trait that has been shown to be as important to scholastic performance as traditional IQ.
By studying the underlying differences in gene expression during healing after a bone break in young versus aged mice, Jaimo Ahn, MD, PhD, assistant professor of Orthopaedic Surgery at the Perelman School of Medicine, University of Pennsylvania, and his colleagues aim to find specific pathways of fracture healing in humans.
Sharon Thompson-Schill of the School of Arts and Sciences is quoted about studying the effect on creative thought by sending electricity through the brain.
Penn Researchers Show that Suppressing the Brain’s “Filter” Can Improve Performance in Creative Tasks
The brain’s prefrontal cortex is thought to be the seat of cognitive control, working as a kind of filter that keeps irrelevant thoughts, perceptions and memories from interfering with a task at hand.
Now, researchers at the University of Pennsylvania have shown that inhibiting this filter can boost performance for tasks in which unfiltered, creative thoughts present an advantage.
