Boravak u svemiru utiče na podmlađivanje organizma? Evo šta je pokazalo istraživanje sa astronautima
Naučnici proučavaju da li boravak u svemiru čini da telo stari brže ili sporije nego na Zemlji.
TL;DR
- Scientists are investigating whether space travel accelerates or slows down human aging.
- A study examined 32 biological aging markers in four astronauts using DNA methylation analysis.
- During spaceflight, astronauts' average epigenetic age increased by nearly two years.
- Upon returning to Earth, all astronauts showed a decrease in biological age, with some becoming younger than before the mission.
- The research suggests spaceflight causes rapid but reversible epigenetic changes associated with aging.
- Spaceflight is proposed as a platform for studying aging mechanisms and testing anti-aging interventions.
