NASA administrator Jim Bridenstine has called out India’s anti-satellite missile test for creating hundreds of pieces of orbital debris that could threaten the International Space Station. “That kind of activity is not compatible with the future of human spaceflight,” said Bridenstine. Indian Prime Minister Narendra Modi announced last week that the country had shot down its own satellite with a ground-to-space missile. India said that any debris would soon fall to Earth, but Bridenstine said that the short-term risk to the International Space Station was still “unacceptable”. A similar test done by China in 2007 is one of the biggest sources of space debris ever.

Duke University’s huge misconduct fine is a casualty of a culture that prizes impact over robustness, argues microbiologist and immunologist Arturo Casadevall. “The seeds of misconduct, although they grow in only a very few individuals, are planted in the very heart of academic biomedical sciences”, he says. He proposes how to make the difficult but necessary culture shift to valuing rigour over impact.

“Spawn till you die” reads the classic salmon-themed T-shirt from artist Ray Troll. But some rare salmon survive spawning and make the gruelling return trip from river to sea over and over. These survivors are called ‘kelts’, and scientists are only starting to understand why they live when so many others die.
