Gregg Semenza received the 2019 Nobel Prize in Physiology or Medicine for discovering how the body's cells sense and react to low oxygen levels. Read more

​With over 30 years of experience studying neurodegenerative diseases, Ted and Valina Dawson are paving the way for new treatments for Parkinson's disease. Read more.

Scientists report success in using a cocktail of cell-signaling chemicals to further wind back the biological clock of human embryonic stem cells. The results can help in developing better therapies. Read more.

Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and Alzheimer's. Researchers have pinpointed the protein that delivers the fatal strike by carving up a cell's DNA. Read more.

Researchers report they have identified a protein that enables a toxic aggregate to spread in a mammal's brain. This suggests that an immunotherapy already in clinical trials as a cancer therapy could also be tested to slow the progress of Parkinson's disease. Read more.

Scientists report they have delivered stem cells to the brain by threading a catheter through an artery and infusing the cells under real-time MRI guidance. This new technique could be used to treat Parkinson's disease, stroke, and other brain damaging disorders. Read more.
