Now on @sciam.bsky.social: After 40 years of searching, physicists have glimpsed a telltale flash of light in a mile-deep cavern. It might be the best-yet evidence for dark matter, the mysterious invisible stuff that outweighs matter 5-to-1. Or it might be a mirage...

How can individual laboratories decide on the best ways to use AI to enhance their work? It depends on the research values that your team prioritizes, a new white paper suggests. #AI By @jennaahart.bsky.social @nature.com 🧪 www.nature.com/articles/d41...

What’s your lab’s archetype? The answer could inform how you use AI

A remarkable shot by John Kraus of the launch this morning of NASA's new Nancy Grace Roman Space Telescope. Liftoff was at 7:26 am Eastern; the spacecraft will take about three months to climb up to the second Sun–Earth Lagrange point. Roman will search for dark matter, dark energy, and exoplanets.
A SpaceX Falcon Heavy rocket transits the Sun. The hot gasses from the liquid-fuelled boosters create complex refraction patterns that distort sunlight at lower left. Shockwaves from the rocket's 27 engines emanate in arcs that break up the Sun's outline.
