On a weekend in mid-May, a clandestine mathematical conclave convened. Thirty of the world’s most renowned mathematicians traveled to Berkeley, Calif., with some coming from as far away as the U.K. The group’s members faced off in a showdown with a “reasoning” chatbot that was tasked with solving problems they had devised to test its … Read more

These implants also cannot fully replicate the nuance of natural hearing. But recent research my colleagues and I conducted has shown that a form of gene therapy … Read more
Tremendous tilts of Mars’ rotational axis during the past 20 million years may have dried out the planet, according to a new study. The findings may help solve the mystery of how Mars, which once contained lakes, rivers and possibly oceans, lost its water. Dry, dust-filled deserts cover much of Mars’ surface today. Astronomers think … Read more

Colossal announced on Tuesday (July 8) that its scientists and local Indigenous partners will “bring back” the South Island giant moa (Dinornis robustus) … Read more
A new artificial intelligence (AI) model can predict and simulate human thought and behavior with a surprising degree of accuracy. The language model, called Centaur, could help researchers improve our understanding of human cognition. The model was trained on more than 10 million real decisions made by participants of psychological experiments. Using this dataset, Centaur … Read more
The roar of the arena crowd, the bustle of the Roman forum, the grand temples, the Roman army in red with glistening shields and armor — when people imagine ancient Rome, they often think of its sights and sounds.

Astronomers have captured the first evidence of a “planet with a death wish” — an alien world that’s orbiting so close to its star and so fast that it’s causing the star to cook it to death with stellar explosions. The planet, called HIP 67522 b, is a wispy, Jupiter-size planet bound on a tight, … Read more
