THE ATACAMA DESERT, Chile (AP) — It takes a moment for the eyes to adjust. A faint spark appears in the darkness; then another, brighter one. Soon, stars, planets and entire constellations emerge.…

A team of geologists has found for the first time evidence that two ancient, continent-sized, ultrahot structures hidden beneath the Earth have shaped the planet's magnetic field for the past 265 million years.These two masses, known as…

This brain drain appears to be real. I spoke to Jared Kaplan, co-founder of Anthropic, the company behind the chatbot Claude. He was a physicist the last time we spoke. As a grad student at Harvard in the 2000s, he worked with the…

Astronomers using NASA’s NuSTAR X-ray telescope have confirmed that a compact star named M82 X-2 shines about 10 million times brighter than the Sun, apparently pushing past a long trusted brightness limit in physics.The object sits in…

The first results from the world's largest neutrino detector have just been published, and they reveal the most precise measurements of neutrino parameters yet.After running the detector — the Jiangmen Underground Neutrino Observatory…

Human sperm can swim through surprisingly viscous fluids with ease – and they seemingly defy Newton's third law of motion to do so.To figure out how they slither through substances that should, in theory, resist their movement, a…

A new study challenges the widely accepted idea that the universe began with a rapid expansion known as inflation. Instead, researchers from Spain and Italy propose that gravitational waves, predicted by Einstein over a…
