What's more, according to their analysis of modern human DNA, one of these isolated populations left a stronger legacy in our genes than the other. "The question of where we come from is one that has ...

Microgravity affects various aspects of the human body. According to NASA, microgravity leads to changes in fluid distribution, muscle loading, and altered signalling pathways. Some basic changes ...

However, the human body evolved to function in the gravity of Earth. So time in the weightlessness of space can take years from which to fully recover. Astronauts Suni Williams and Butch Wilmore ...

Spending months in microgravity is brutal on the body. Without the Earth’s gravitational pull, muscles shrink, bones weaken and bodily fluids shift. Astronauts lose muscle mass rapidly because ...

Future drugs and even gene therapies could enhance the body's defenses against space radiation. "There's a lot of research into that area," said Urquieta. Preventing infighting among teams will be ...

For the last two decades, the prevailing view in human evolutionary genetics has been that Homo sapiens first appeared in Africa around 200,000 to 300,000 years ago, and descended from a single ...

Some of the genes from Population B, "particularly those related to brain function and neural processing, may have played a crucial role in human evolution," study co-author Trevor Cousins, a ...

Article continues below Space is a pretty hostile environment for the human body, meaning this prolonged stay on the space station likely had a significant impact on the astronauts' health ...

There isn't any reason to suggest that human intellect has been harmed, the publication counters — but in "both potential and execution," our intelligence is definitely on the downturn.
