Researchers at the University of Rochester Medical Center have developed a new imaging technique that could revolutionize how eye health and disease are assessed. The group is first to be able to make out individual cells at the back of the eye that are implicated in vision loss in diseases like glaucoma. They hope their new technique could prevent vision loss via earlier diagnosis and treatment for these diseases.
Elevated levels of the brain protein tau following a sport-related concussion are associated with a longer recovery period and delayed return to play for athletes, according to a study published in the January 6, 2017 issue of Neurology®, the medical journal of the American Academy of Neurology. The findings suggest that tau, which can be measured in the blood, may serve as a marker to help physicians determine an athlete’s readiness to return to the game.
Researchers supported by the Swiss National Science Foundation have succeeded in using X-rays to minutely observe a photosynthesis reaction and produce a movie of the event. The findings will aid understanding of similar processes in the human eye. Thanks to the new SwissFEL particle accelerator at the Paul Scherrer Institute, we can expect more discoveries of this kind.
A key glacier in Antarctica is breaking apart from the inside out, suggesting that the ocean is weakening ice on the edges of the continent.
