A Cave Full of Strangers, and Not One of Them Is Male
20 Homo naledi fossils. One cave. Zero males. Was a small-brained human relative practicing sex-specific burial rites hundreds of thousands of years before we were?
We Moved the Planet. Slightly. With Irrigation.
Researchers needed 2,150 gigatons of missing groundwater to make their models match reality. What they found when they added it in was the planet itself, quietly keeping score.
Woman Buried With Her Own Bones Turned Into Tools
Her brain was removed, her bones sharpened into tools, then carefully reassembled and buried. Was this reverence, ritual, or something else entirely?
Fire Tornado Set to Clean Oil Spills
The old fix for an ocean oil spill was to burn it and live with the smoke, soot, and sludge. What if the problem wasn't the fire, but the shape of it?
The Planet Bombed Itself Into a Cradle
Asteroid impacts were supposed to be the enemy of life. New research suggests the early Earth's craters made life possible.
Two Sheets of Carbon, One Tiny Twist, and Suddenly Electricity Flows for Free
Researchers discovered superconductivity can be switched on and off by changing a material's surroundings, not the material itself. What does that mean for everything built on electrons?
Physics Sorted Magnets into Two Bins for a Century. The Third Bin Has 200 Entries.
A third magnet type has been hiding in plain sight. A flawed diamond might be what finally proves it exists.
The Sun's Interior and Its Surface Are No Longer Telling the Same Story
Scientists have listened to acoustic waves inside the Sun since 1987. What they're hearing in the current cycle diverges significantly from what four centuries of surface observation would predict.
This Galaxy Has No Spin
A massive early galaxy stopped forming stars and lost its spin before the universe was 2 billion years old. How does a galaxy grow old so fast?
Hidden Traps in Antarctic Ice Shelves Supercharge Melting
The underside of Antarctica's ice shelves is riddled with hidden channels that are doing something the climate models didn't predict.
Sugar Maple Has Defined Michigan's Forests for Centuries. Its Own Seedlings Are Replacing It.
Michigan has more sugar maples than any state in the country. Something is already replacing them. It's been growing in the understory for 25 years.
Climate Didn't Kill the Neanderthals. Loneliness Did.
They survived dozens of ice ages. Viable habitat wasn't the problem. What killed Neanderthals was the slow collapse of social connections.
Dead Stars Have Been Snowing on Antarctica for 80,000 Years
Iron-60 doesn't form on Earth. So why is it showing up in 80,000-year-old Antarctic ice — and what dead star left it there?
Your Heart Beats Back Cancer
The heart's constant mechanical pressure suppresses tumor growth. The protein behind it could reshape how we approach cancer treatment.
A Ghost Galaxy Called Loki Is Lurking in the Milky Way
Ancient stars hiding in the galactic plane share identical chemistry but opposite orbits. Remnants of a galaxy the Milky Way devoured at the dawn of time.
The Cyclops Ancestor We All Share Left Its Eye Inside Your Brain
Every vertebrate alive shares a one-eyed worm ancestor. The original eye didn't disappear — it's still in your skull, running your circadian rhythm right now.
An Unknown Object Has Been Keeping a 44-Minute Clock. Astronomers Just Found Out It Has Two Hands.
It has pulsed every 44 minutes for longer than anyone has been watching. Astronomers just found a second signal running in perfect sync — and the physics for it doesn't exist yet.
