Flatworms offer clues to brain repair, grandkids might help your brain, and Australia probes an AI hack of health data.
CLEVELAND — A tiny flatworm may hold clues to repairing the human brain.
When brain cells die in people, the tissue scars instead of rebuilding. Flatworms called planarians can regrow an entire brain from a small sliver of tissue.
Researchers at the University of Georgia identified nearly a dozen genes that turn the worms' stem cells into dopamine-making neurons. When those genes shut off, the worms slow down, much like people living with Parkinson's disease.
Scientists hope the findings could someday lead to better stem c...
