Tech giants and car manufacturers alike are developing self-driving cars, and some of them are already on public roads. But what must computers be capable of to truly take the wheel? And could they eventually be safer than human drivers?
Scientists investigate the bizarre "intelligence" of slime molds, which appear to learn and make decisions — without a brain. These cunning, single-celled blobs can navigate mazes and create efficient networks. Can they also redefine cognition?
Our DNA can determine attributes from eye color to medical predispositions. An extraordinary technology called CRISPR allows us to edit human DNA, possibly eliminating genetic diseases or choosing our children's features. But how far should we go?
The coronavirus SARS-CoV-2 has upended life as we know it in a matter of mere months. But at the same time, an unprecedented global effort to understand and contain the virus-and find a treatment for the disease it causes-is underway.
When top predators disappeared from Mozambique's Gorongosa National Park, other animals fell into unusual patterns. Now scientists are reintroducing wild dogs to restore the park's "landscape of fear" and with it the natural balance of the ecosystem.
When the Notre Dame cathedral caught fire in April 2019, Paris came perilously close to losing over 800 years of history. As engineers rebuild, researchers use cutting-edge technology to piece together what happened and restore the cathedral.
What makes eagles so remarkable? Researchers study one special bird, revealing her exceptional strength, eyesight and flying skills. Meanwhile, in-the-nest footage of a new bald eagle family captures the drama of chicks struggling to survive.
Scientists are coming to understand fat as a system akin to an organ — one whose size may have more to do with biological processes than personal choices. Explore the mysteries of fat and its role in hormone production, hunger and even pregnancy.
When the U.S. trade embargo left Cuba isolated from medical resources, Cuban scientists developed their own biotech industry — and promising lung cancer vaccines. Can they now team up with U.S. partners to make the treatments available to all?
From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a vulnerable, defenseless state? Scientists are peering more deeply into the sleeping brain than ever before.
They may have stolen many hearts-and the internet-but cats can be perplexing pets. As much cuddly and playful as they are aloof and uncaring, they've often raised the question: Did humans ever really domesticate felines?
