The NASA Twins Study was conducted. Astronaut Scott Kelly is selected for the mission with his identical twin, Mark Kelly, on earth as control group. Scott spent 340 days in space for the experiment. The result demonstrated several long-lasting changes, including those related to alterations in DNA and cognition. [3] [4]
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 ...
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 ...
On 12 April 2019, NASA reported medical results from the Astronaut Twin Study, where one astronaut twin spent a year in space on the International Space Station, while the other spent the year on Earth, which demonstrated several long-lasting changes, including those related to alterations in DNA and cognition, after the twins were compared ...
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.
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 ...
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.
