Long-term space travel to Mars could be bad for astronauts’ hearts, a new zero-gravity study shows. After a month at the International Space Station, a set of 48 bioengineered human heart tissue samples beat about half as strong as similar tissues that remained on Earth. Advertisement
The tissues also became weaker and started showing genetic evidence of inflammation and oxidative damage that are hallmarks of heart disease, researchers reported Monday in the Proceedings of the National Academy of Sciences.
