When Astronauts Enter Space, a "Dark Genome" Activates in Their DNA
Image by Getty / NASA / Futurism Studies Researchers have found that human stem cells are constantly under stress in the microgravity of space — activating hidden, ancient sections of DNA called the "dark genome." In a study published in the journal Cell Stem Cell last week, a team of researchers led by Sanford Stem Cell Institute director Catriona Jamieson used a cellphone-sized device on board the International Space Station to watch how stem cells behave in space for the first time. They f
