Physicists have long believed that black holes explode at the end of their lives, and that such explosions happen — at most — only once every 100,000 years. But new research published in Physical Review Letters by physicists at the University of Massachusetts Amherst has found a more than 90% probability that one of these…
A billion dollars isn’t what it used to be—but it still focuses the mind. At least it did for me when I heard that the AI company Anthropic agreed to an at least $1.5 billion settlement for authors and publishers whose books were used to train an early version of its large language model, Claude….
A greedy white dwarf star not far from Earth is devouring its closest celestial companion at a rate never seen before, space scientists have discovered. Their study found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy. Experts think…

On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of light — but it was not made of light. It was a different kind of signal:…
For over a hundred years, schoolchildren around the world have learned that ice melts when pressure and friction are applied. When you step out onto an icy pavement in winter, you can slip up because of the pressure exerted by your body weight through the sole of your (still warm) shoe. But it turns out…
Routine vaccination rates for kindergarten children have declined since the COVID-19 pandemic began, while exemptions from school vaccination requirements, particularly non-medical exemptions, have increased. These trends coincide with shifting attitudes toward childhood vaccination likely fueled in part by vaccine misinformation. The past few years have seen more skepticism and confusion among the public about the…
If you pull an ice core from the outer edges of the Arctic polar cap, you might spot what looks like a faint line of dirt. Those are diatoms – single-celled algae with outer walls made of glass. Their presence in ice isn’t new, but because they seemed trapped and dormant, few bothered to study…
Key Points First observed on September 5, Yurei is a newly emerged ransomware group that targeted a Sri Lankan food manufacturing company as its first leaked victim. The group follows a double-extortion model: they encrypt the victim’s files and exfiltrate sensitive data, and then demand a ransom payment to decrypt and refrain from publishingthe stolen information….
