A couple of preliminary studies in recent years have found that astronauts' telomeres grow longer while in space. Telomeres are caps at the ends of your chromosomes that protect against damage. As ...
The mission supported the NASA Twins study, which helps shed light on the health effects of long-duration spaceflight. [11] The goal aboard the orbiting laboratory was to understand better how the human body reacts and adapts to the harsh environment of space. [9] Data from the mission was used to improve assessments of crew performance and health.
NASA's Scott Kelly spent a year on board the International Space Station to test the effects of space travel on his body, while his identical twin and fellow astronaut Mark Kelly remained on earth.
Twins Scott Kelly and Mark Kelly are taking part in an ongoing first-of-its-kind twin study with NASA.
Telomeres at the end of a chromosome. The relationship between telomeres and longevity and changing the length of telomeres is one of the new fields of research on increasing human lifespan and even human immortality. [1] [2] Telomeres are sequences at the ends of chromosomes that shorten with each cell division and determine the lifespan of ...
In 2013 NASA published a study that found changes to the eyes and eyesight of monkeys with spaceflights longer than 6 months. [85] Noted changes included a flattening of the eyeball and changes to the retina. [85] Space traveler's eyesight can become blurry after too much time in space. [86] [87] Another effect is known as cosmic ray visual ...
A telomere (/ ˈ t ɛ l ə m ɪər, ˈ t iː l ə-/; from Ancient Greek τέλος (télos) 'end' and μέρος (méros) 'part') is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes (see Sequences). Telomeres are a widespread genetic feature most commonly found in eukaryotes.
Another study found little evidence that, in humans, telomere length is a significant biomarker of normal aging with respect to important cognitive and physical abilities. [ 39 ] Some experiments have raised questions on whether telomerase can be used as an anti-aging therapy , namely, the fact that mice with elevated levels of telomerase have ...
