OpenAI stunned the mathematics community this week with the release of nearly 400 solutions to open math and statistical problems. But how they were generated remains unclear and contentious.

A massive pulse of water called a "Kelvin wave" is heading toward California. It's one of many expected this winter and they serve as a preview of what's to come because of climate change.

Last month was the hottest September ever recorded in the contiguous U.S.—a sobering record for an already historically hot year.

Knitting is fun—and easy to mess up. In a recent study, mathematicians used knot theory to design a new type of knitting stitch that stops mistakes from spreading across the fabric.

The giant tortoise Jonathan was fully grown at around 50 years old in an 1882 photo. Here are the genetics that might keep him going today at 194.

NASA’s Artemis II lunar mission may be more than half-year in the rearview, but it’s still got more to show us. The space agency has just released more than 800 gigabytes of sights and sounds from the crew’s close encounter with the Moon.

World health experts are closely following a potential case of pneumonic plague—the most deadly form of the disease. Here's everything you need to know.

Cannabis can be relaxing—or it can cause anxiety and paranoia. Scientists have long wondered why weed can have these effects, and new research hints that something may be happening to the amygdala—the brain's emotional center. Here's what to know.

AI developers spend fortunes training their models. By asking the models enough questions, rivals can copy that work through a technique known as distillation.

From the archive (Jan 2026): Researchers are closer to making “reversed” cells that mirror cells found in nature. Experts warn that such cells could destroy life on Earth. The 2026 Nobel Prize in Chemistry was awarded to the foundational work in understanding such cellular geometry.

BREAKING: The 2026 Nobel Prize in Chemistry is awarded to Henri Kagan and Kenso Soai for their pioneering work in "mirror" chemistry.

The newly discovered "demon cave fish" was discovered in the caves near an Alabama military installation. It's named after the monster from the Netflix series Stranger Things.

OpenAI's latest math dump has arrived. It consists of hundreds of new results to important problems, from the same internal model that produced a million-dollar math proof last month. It could take mathematicians years to sift through it all.

FROM THE ARCHIVE (2015) by 2026 Nobel Prize in Physics winner Francis Halzen. Dozens of particles from halfway across the universe have landed in the IceCube experiment. These messengers could help answer some long-standing cosmic conundrums.

BREAKING: 2026 Nobel Prize for Physics awarded to Francis Halzen for the discovery of high-energy neutrinos, “ghostly messengers from space.”

Mathematicians saw a simple string hooking a painting onto two nails and thought, “We can make it worse.”

2026 has been a record hot year for the U.S. If it stays that way, 2026 could set a sobering new record.

AI companion apps are becoming increasingly popular, but what kind of relationship do they offer? An attachment theory expert explains.
