Two spacewalks this winter fixed the power supply of China's Tiangong space station, which was damaged by a space debris strike, state media reported.

AI companies are trying to impose safety measures on their chatbots, while researchers are finding ways around them all the time. Where will this end, asks Alex Wilkins

Feedback is pleased to see that researchers are looking into the urgent issue of which angle blood might travel at following a violent act in space

Cancer has been one of the world's most feared diseases for decades. But this "cancerphobia" no longer matches the evidence and is doing great harm, argues David Ropeik

Ural River levels peak in this April 13, 2024, enhanced color image from Landsat 9; here, vegetation appears red, while water is blue-green. After heavy rain and rapid snowmelt, rivers in southern Russia and northern Kazakhstan swelled, flooding homes and displacing thousands of people.

Landsat 9, the latest satellite in the Landsat series, contributes a critical component to the international strategy for monitoring the health and state of the Earth, allowing more frequent observations. Data from Landsat 9 can be used to inform decisions in key areas like urban expansion, coral reef degradation, and natural disasters.
