OpenAI announced today that it had solved the problem, one of seven “Millennium Problems” seen as among the most important in higher mathematics.

The company’s announcement is the most dramatic sign yet that artificial intelligence is fundamentally transforming the field of higher mathematics.

No company in the United States has ever restarted a reactor that was seemingly closed for good, but there are now three major efforts underway to do so.

Doctors were hopeful the drug, which was being tested in a large clinical trial by Novartis, was going to be a powerful new tool to fight heart disease.

Jacob Tsimerman, a recent recipient of the Fields Medal, believes that higher mathematics can help curb the dangers of runaway artificial intelligence.

Traditional gene editing rewrites DNA. But a new approach, called epigenome editing, aims to treat the molecular scars we collect throughout our lives.

The Japanese chemist played a key role in the discovery of electricity-conducting plastics, largely by accident.

Artificial intelligence was used to help develop a drug candidate, rentosertib, for a rare lung condition. Its maker says the drug also seems to reduce the biological hallmarks of age.

A Mesopotamian culture’s decorated ceramics show some early roots of math, researchers argued.

Joan Birman thought her major discoveries were behind her. Then came an email from a young neighbor — a girl who knew little but wanted to learn.

Researchers want to explore the idea that microscopic particles shed by alien civilizations have accumulated on the lunar surface, making it an archive of extraterrestrial technology.

As Dr. Anthony Fauci has faced public scrutiny from congressional Republicans, the D.O.J. has pursued a quieter and more expansive effort against a wider circle of researchers.

Under a new partnership, the Defense Department would play a larger role in biodefense and pandemic preparedness. Democrats warned it could allow a Pentagon cash grab.

Meet the earliest known insects. Shaking hands with them will take a while.

For the marine archaeologist Sean Kingsley, the most honest history can be found on the seafloor.

The preliminary research was conducted in mice, but scientists were optimistic the results would apply to humans. Clinical trials begin this month.

More than one million genomes helped identify DNA variants linked to extroversion, agreeableness, neuroticism and more. Researchers measured how those traits influenced how people lived.

Scientists spent over a decade reconstructing the calls of nine species of ancient insects to create the first accurate Jurassic soundscape.

For the first time in a year, the U.S.-Mexico border partly reopened to cattle imports following a screwworm infestation across the region. The battle against the flesh-eating fly has only just begun deep in Mexico.

A lone signal from an experiment in South Dakota doesn’t fit the profile of any other known particles, physicists say.
