Online prediction markets are taking bets on everything from climate change to quantum computing. But researchers question their accuracy

Like astronauts’ “overview effect,” a dramatic feeling of awe takes hold on extended seafloor stays

The maker of Claude wants AI labs, including itself, to prepare for a coordinated slowdown if models begin building their own successors

NASA ordered its astronauts to take refuge inside a docked SpaceX Crew Dragon spacecraft and to prepare for potential evacuation of the International Space Station. But the crew returned to normal operations shortly afterward

The FDA's ongoing review of mifepristone could skip over established science, health experts warn

Mammograms, which are key to detecting breast cancer, could be paired with artificial intelligence to predict heart disease risk, too. Researchers have developed an AI model that scans mammograms to quantify bright streaks of calcium buildup, a marker of stiffened breast artery tissues. The severity of these so-called breast arterial calcifications (BAC) can help to predict associated heart disea…

Planets might exist in the least likely place you’d imagine—around the outskirts of supermassive black holes

A physician involved in the long push to change the name PCOS to PMOS takes us behind the scenes of this subtle yet consequential change

At a White House briefing on Thursday, President Donald Trump invoked a national defense law to steer nearly $700 million to support coal power plants and exports. Trump aims to use the 1950 Defense Production Act to refurbish 13 coal plants, build two new ones and establish a West Coast coal export facility in the U.S.—even as many coal plants around the country are retiring and the fossil fuel …

Remote and hybrid work can have benefits, but a study involving more than 588,000 people suggest they may take a serious mental toll

Bumblebees appear to be capable of coming up with creative solutions to new problems to get a sugary reward—and their strategies include cheating

A new investigation alleges that official organizations in Tanzania have imperiled the country's artifacts and remains at four critical human heritage sites they were supposed to protect

This marks the first case of the New World screwworm in U.S. livestock since the parasite was eliminated in the country in the 1960s

At the heart of our home galaxy lurks a gigantic black hole that’s more than a trillion times heavier than Earth, with all that mass stuffed into a region that is about 2,000 times wider than our planet. Now scientists have discovered the behemoth is throwing off a hot breeze. The findings, detailed today in the Astrophysical Journal Letters, suggest not only that all black holes emit such a wind…

A blip of light in the outer reaches of the Milky Way might be a bizarre black hole born at the beginning of time itself—and the long-sought solution to the mystery of dark matter. Astronomers are calling it “Phoebe”

Culture is humanity’s secret for world domination. This calculation shows just how powerful it is

Even though astronomers didn’t detect alien tech signals from a rare interstellar visitor, the results are worthwhile, they say

This prototype could help the world prepare for AI malware threats, according to the researchers who made it

Unprecedented results against a stubbornly hard-to-treat cancer are boosting optimism that other challenging tumors will be next

MAVEN was the first mission designed to study the atmosphere of Mars. It also became a vital node of NASA’s communications network at the Red Planet
