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.
