telomere

However, it’s still not clear whether that relationship is causal, and it’s likely that multiple processes affect telomere length.

Several studies have found that higher levels of physical activity are related to longer telomere lengths in some people, compared to those who are sedentary.

So in the stressful environment of spaceflight, you’d expect telomeres to shrink.

Quite to our surprise, we saw elongated telomeres in both of the climbing twins.

Subsequently, telomeres returned to near normal length after the astronauts returned to Earth.

Scientists now view telomere length as an overall marker of biological aging.

Harley, 58, is a pioneer in telomere research, and a rigorous scientist.

But it's only now that the medical community is closing in on telomere testing for the average patient.
