New imaging technology could help find tiny tumors

Many types of cancer could be more easily treated if they were detected at an earlier stage. MIT researchers have now developed an imaging system, named "DOLPHIN," which could enable them to find tiny tumors, as small as a couple of hundred cells, deep within the body.

Sleep apnea may be related to higher accumulation of Alzheimer's biomarker in the brain

People who are witnessed by a bed partner to have stopped breathing during sleep may have higher accumulations of an Alzheimer's disease biomarker called tau in an area of the brain that helps with memory, according to a preliminary study released today that will be presented at the American Academy of Neurology's 71st Annual Meeting in Philadelphia, May 4 to 10, 2019.
