Princeton University researchers used a high-throughput — meaning many materials can be examined at once — screening process developed at Princeton to discover an organic compound that prevented the formation of protein clumps found on human brain cells afflicted by Alzheimer's disease. Fruit flies bred to exhibit Alzheimer's-like symptoms maintained their climbing ability after receiving the compound — called D737 — for two weeks (left), whereas flies that did not (right) get treatment exhibited the disorientation and loss of mobility associated with Alzheimer's.
