Interesting that telomere length increased by 14% during flight! And, it can’t be related to a healthy lifestyle since they got shorter within 48hrs back on earth?

Notably, telomere length shortened rapidly upon TW’s return to Earth, within ~48 hours [FD340 ambient return to R+0 (R+ days post return); fig. S6B] and stabilized to near preflight averages within months.

I am not a doctor, but my understanding is that increasing telomere length could contribute to the severity of malignant tumors.

or increase life length!? Space hypersleep might become a thing after all.

It's a double edged sword. Increased telomere length will not only make it easier for your normal cells to divide more, it makes it easier for cancer cells to divide more. It's actually an anti-cancer adaptation for some mammals to turn off their telomere repair.
