Muscle loss in space occurs primarily in body parts responsible for walking and posture support, such as lower limbs and the trunk. Studies suggest this phenomenon is a direct result of muscle cells ...

They say travel broadens your mind but, if you’re travelling into space, it could displace your brain. Results of new study add to a growing body of evidence that astronauts’ brains change position ...

When scientists sent bacteria-infecting viruses to the International Space Station, the microbes did not behave the same way they do on Earth. In microgravity, infections still occurred, but both ...

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold ...

As the human race looks toward a future of space exploration and perhaps even colonization, one new discovery sheds light on a potential challenge. Traveling and being in space changes the shape of an ...

The International Space Station (ISS) is one of the most unique environments where life has ever existed, out in the low orbit of Earth. And research out today finds that bacteriophages—the viruses ...

Evolutionary biology professor Scott Solomon breaks down what changes the Artemis II crew are experiencing in space and how that will look like by the end of the mission. Trump’s ominous warning to ...
