Study: Cognitive ability is a whole-brain phenomenon

Science
March 27 (UPI) -- New research suggests intelligence, or general cognitive ability, can't be traced to a single region of the brain. According to an international team of neuroscientists, cognitive intelligence is a whole-brain phenomenon. For the study, researchers used diffusion tensor imaging to study whether small variations in the the neural wiring systems of test subjects could account for differences in IQ. The international survey involved the brain scans and IQ tests of 1,717 participants from all over the world, including healthy subjects and patients with schizophrenia. Scientists at the National University of Ireland Galway used novel statistical methods to synchronize and analyze the data collected by participating researchers. "To date, this is the largest meta-analysis stu...

Einstein’s ‘spooky’ phenomenon caught on camera for first time

Technology
Scientists have photographed a phenomenon which Albert Einstein called "spooky action at a distance" for the first time. The image is of a strong form of quantum entanglement, where two particles interact with each other and share their physical states for an instant. It happens no matter how great the distance between the two particles. Image: Albert Einstein called the phenomenon 'spooky' The connection is known as Bell entanglement and underpins the field of quantum mechanics.Paul-Antoine Moreau, of the University of Glasgow's School of Physics and Astronomy, said: "The image we've managed to capture is an elegant demonstration of a fundamental property of nature, seen for the very first time in the form of an image. ...
