Analyzing dozens of cases around the world yields some practical lessons. Generally, when you hear “water use” and “sustainability,” you expect those words to be followed by some bad news.

BROOMFIELD, Colorado—One of NASA’s oldest astronomy missions, the Neil Gehrels Swift Observatory, has been out of action for more than a month as scientists await the arrival of a pioneering robotic rescue mission. The 21-year-old spacecraft is…
Policymakers debate if we even need deep ocean mining and if we can do it safely. More than 13,000 feet below the surface of the Pacific Ocean, a more-than-70-ton machine trundled like a tank on its caterpillar tracks for a tenth of a mile—sucking up potato-sized nodules of rock…
This week’s result is just the latest in a growing collection of discoveries. On Monday, a paper announcing that all four DNA bases had been found on an asteroid sparked a lot of headlines. But many of the headlines omitted a key word needed to put the discovery in…
“Assume the NRC is going to do whatever we tell the NRC to do.” Last summer, a group of officials from the Department of Energy gathered at the Idaho National Laboratory, a sprawling 890-square-mile complex in the eastern desert of Idaho where the US government built its first rudimentary…

“Reducing unnecessary Copilot entry points” is one of Microsoft’s action items. If you were eating in a restaurant and the head chef came out from the back multiple times to loudly proclaim that the kitchen was deeply committed to the quality of the food, would you find that reassuring?…
Admins: Sorry to say, but it’s likely a rotate-your-secrets kind of weekend. Hackers have compromised virtually all versions of Aqua Security’s widely used Trivy vulnerability scanner in an ongoing supply chain attack that could have wide-ranging consequences for developers and the organizations that use them. Trivy maintainer Itay Shakury…
There may be a river delta hidden under the obvious delta in a Martian crater. When NASA’s Perseverance rover landed in Jezero Crater in 2021, its primary mission was to scour the remnants of a dried-up Martian lakebed for signs of ancient life. Scientists have been focused on the…
“We put fuel in a rocket, blow it up in a remote location, and measure how big the boom is.” For more than 60 years, nearly every large rocket used some combination of the same liquid and solid propellants. Refined kerosene was favored for its easy handling and non-toxicity,…
