'Zombie' cells have scientists rethinking how we age — and what to do about it
Summary
Scientists are studying "zombie" cells to understand and possibly change how we age. These cells are affected by stress, which impacts DNA in ways similar to aging.Key Facts
- "Zombie" cells refer to damaged or stressed cells that stop dividing but don't die.
- Research shows that stress impacts DNA changes similar to those seen in aging.
- Scientists are exploring how these cells affect the aging process.
- Regina G. Barber discussed this topic with science journalist Diana Kwon on NPR's Short Wave.
- The episode looks at how stress and aging are connected on a molecular level.
- Shortened telomeres, a part of DNA, are linked to aging and stress.
- Understanding these connections might lead to new ways to slow or reverse aging.
