Scientists are making headway in learning about our great-grand-germ Grandma, is that you? Scientists who have tried to understand early life on Earth say LUCA, the last universal common ancestor, may have been a rod-shaped organism like this one. Usis/iStock/Getty Images Plus Scientists want to identify your earliest ancestor. And to do that, they have […]

Modern formalization, supercharged by AI, could radically change the way people do mathematics Mathematician Kevin Buzzard of Imperial College London is training computers how to prove one of the most famous problems in math history: Fermat’s last theorem. Resolving the problem isn’t the point. There’s already an accepted proof that was finalized in 1998. That work

For four days in February 2019, some 30 synthetic biologists and ethicists hunkered down at a conference center in Northern Virginia to brainstorm high-risk, cutting-edge, irresistibly exciting ideas that the National Science Foundation should fund. By the end of the meeting, they’d landed on a compelling contender: making “mirror” bacteria. Should they come to be,
No one’s sure if synthetic mirror life will kill us all Read More »
IN OCTOBER 2024, Carolina Millon, a former retail executive in Falls Church, Virginia, anxiously checked her email and found a notification that she had new test results from a recent breast biopsy ready to view. She took a deep breath before clicking on the link. As a carrier of mutations in the BRCA2 and CHEK2 genes,
Inspiration from nature’s engineers is helping rescue imperiled waterways One warm morning in the summer of 2025, the Beaver Brigade marched into Bernheim Forest. This woodland spans more than 16,000 acres (6,475 hectares) in north-central Kentucky. Every other month, volunteer brigade members hike in to make it more beaver-friendly. Beavers are nature’s engineers, notes Evan

It’s studded with tiny dots that vibrate to mimic the feel of real-world textures Worn on a fingertip, the new device uses a grid of tiny nodes to simulate textures, such as the feel of fabrics. Northwestern University Phones, tablets and other electronic gadgets display lifelike images and play realistic sounds. What’s next? Maybe, making

Here’s how scientists are solving the “dinosaur death pose” mystery and others. One bright day in April 2023, Hannah Maddox drove 13 hours from Knoxville, Tennessee, to a U.S. Geological Survey (USGS) research station in the Everglades National Park, near the southern bump of Florida. Her mission was simple: Collect 30 frozen, dead Argentine black

Artificial intelligence systems, and large language models (LLMs) in particular, have become almost ubiquitous. The implications are many. Among them: serious concerns about massive amounts of energy usage. The initial training of GPT-3 required as much energy as powering 120 houses for a year. That’s before adding the energy required for the chatbot to respond
Can neuromorphic computing help reduce AI’s high energy cost? Read More »
The Milky Way’s forecast: mostly cloudy. But the origin of these cosmic clouds is unclear Beyond the bright swirling arms of our Milky Way galaxy, something enormous, mysterious and shadowy barrels toward us. It’s called Smith’s Cloud. And it isn’t like any cloud you’ve seen before. From head to tail, it extends more than 11,000 light-years.
Fast, mysterious clouds swarm around our galaxy Read More »
On a snowy night in 2021, four shivering scientists in Michigan set down their shovels and studied a hand-drawn map by flashlight. The map led to a secret location. They traveled in the dark so no one would spy where they were going. If they dug in the right place, they expected to find a
These ultra-long experiments outlive their scientists — on purpose Read More »
