Tyrannosaurus rex was a hottie with a body temperature similar to our own, according to a new analysis of their teeth. The finding supports the idea that T. rex was a fast, energetic predator and scavenger, not an animal that basked in the sun to gain energy like most modern-day reptiles. T. rex, which lived […]

Around 700 million years ago, a group of organisms resembling little more than glowing, gelatinous blobs split off from the rest of the animals, forming possibly the earliest branching animal lineage. Nearly 200 species of ctenophores, commonly known as comb jellies (but unrelated to jellyfish), live today in environments ranging from the cold depths of

The rings around a strange small body orbiting between Saturn and Uranus look mysteriously different from previous views, new observations from the James Webb Space Telescope (JWST) suggest. The rings encircle Chariklo, which is a centaur, a strange type of object that shows characteristics of both asteroids and comets. Chariklo is only about 400 miles

Artificial intelligence (AI) terrifies us partly because it is new and partly because it is disturbingly familiar. We have invented machines that converse, flatter, argue and improvise with

Climate change is often discussed in terms of rising temperatures, extreme weather and environmental loss. But there’s another consequence that can be harder to see: The impact on our mental health. In this exclusive video, we explore how heat exposure influences mental state, drawing on research by Kim Meidebauers, a neuroscientist at Washington State University

A volcanic eruption 22 million years ago froze a snapshot of the Andes in their youth, revealing a slow-and-steady formation of this formidable mountain range. The eruption, which originated from the Lauca Caldera in what is now northern Chile, blanketed the landscape in a formation known as ignimbrite. This rock is left over after a

Many astronomers concluded that big black holes dotted the universe, washing out the light of the stars in their host galaxies. As black holes, the little red dots would appear red because dust — grainy stuff much more complicated than gas — was blocking their blue light. Yet they still seemed weird. Most supermassive black
