But in the near-zero gravity of space, leg muscles suddenly have little to do. To mimic this abrupt change, Donahue and his colleagues subjected mice to simulated microgravity by strapping tape around ...

A suitcase-sized quantum sensor could soon reveal hidden water, oil, and even underground mountains—all by tracking how atoms ...

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have ...

This mission will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of ...

On Earth, fluids tend to accumulate in the lowest area, but in space, "where due to the absence of gravity there is no up or down, the body has to adjust to the volume of fluid that on Earth is in ...

"We could determine the mass of the Himalayas using atoms," Jason Hyon, chief technologist for Earth Science at NASA's Jet ...

But for astronauts stationed in space, taking a quick rinse—much ... everyday task—becomes a lot more complicated due to the ...

Effects of Microgravity on the Brain - Another major concern for astronauts spending extended periods in space is the effect of microgravity on the brain. The absence of gravity causes bodily ...

The absence of gravity means that muscles do not need to work as hard to support the body, leading to significant muscle loss. Despite rigorous exercise routines in space, astronauts still ...
