Light scattered in tissue usually ceases to be a useful source of information. But what if, instead of forcing it to travel along a single path, we allowed it to wander a little differently each time? Scientists from ICTER tested this seemingly risky idea and showed that a series
Light scattered in tissue usually ceases to be a useful source of information. But what if, instead of forcing it to travel along a single path, we allowed it to wander a little differently each time? Scientists from ICTER tested this seemingly risky idea and showed that a series of measurements that differ from one another can produce a clearer image than a single frame.

Scientists expected these Galápagos sea turtles to wander. They stayed put
Yellow-morph green sea turtles in the Galápagos surprised scientists by staying remarkably close to home instead of making the long journeys typically associated with sea turtles. Satellite tracking showed that none left the marine reserve during the study, revealing just how imp

Scientists found a surprising driver of Alzheimer’s outside the brain
Scientists found that immune cells contributing to Alzheimer’s-related brain damage may be activated in lymph nodes outside the brain before traveling into the nervous system. Blocking this pathway in mice dramatically reduced neurodegeneration and preserved cognitive abilities,
