There are at least a dozen trials worldwide testing low-dose radiation therapy, or LDRT, as a treatment for pneumonia related to Covid-19, some spurred by the same historical data Calabrese and colleagues scoured years ago. The theory: Targeted radiation to the lungs will halt the out-of-control inflammation responsible for the devastating pneumonia that bookends the course of some Covid-19 patients.

Sending humans to Mars could leave astronauts with neurological problems, according scientists who studied mice in conditions which they claimed replicate deep space.

Although space travel exposes astronauts to forms of radiation that are uncommon on Earth, and that are linked to cancers and heart problems, a U.S. study suggests this doesn’t significantly shorten their lives.

When SpaceX launches Japanese billionaire Yusaku Maezawa and his eight traveling companions for a trip around the Moon in 2023, the company will be undertaking an unprecedented step toward the future of civilian space flight. But with being the first to attempt this feat comes a number of technical and safety challenges that less ambitious expeditions, like Blue Origin's treks to the Karman Line, won't have to face. So, just how will SpaceX ensure that its first trip to the Moon doesn't turn into a real-life Gravity?

New research from scientists at the University of Nevada, Las Vegas (UNLV) shows that the cancer risk for astronauts undertaking long-term missions to Mars or any other destination beyond Earth’s magnetic field is actually twice what we previously thought.

The cancer risk for a human mission to Mars has effectively doubled following a UNLV study predicting a dramatic increase in the disease for astronauts traveling to the red planet or on long-term missions outside the protection of Earth's magnetic field.
