Andromeda and the Milky Way merge. NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas; and A. Mellinger Share Curious Kids is a series for children of all ages. If you have a question you’d ...

Readers went all-in on biotech this year. Gene editing brought the broad treatment of genetic disease into view; cancer-fighting T cells took on tumors; and scientists found a way to 3D print tissues ...

The treatment reprograms T cells to hunt down a patient's cancer. The approach could speed treatment and cut costs, but needs more study. With just a single injection, a new treatment transforms ...

When brain organoids were introduced roughly a decade ago, they were a scientific curiosity. The pea-sized blobs of brain tissue grown from stem cells mimicked parts of the human brain, giving ...

Our cells are like the ultimate soft robots. Made mostly of a liquid interior wrapped inside a fatty shell, they split, stretch, roam, and squeeze into every nook and cranny of the body. Actual robots ...

Autonomous drones could revolutionize a wide range of industries. Now, scientists have designed a drone that can weave through dense forests, dodge thin power lines in dim lighting, and even track a ...

Our hands are works of art. A rigid skeleton provides structure. Muscles adjust to different weights. Our skin, embedded with touch, pressure, and temperature sensors, provides immediate feedback on ...

Ever since Hugh Herr lost both his legs to a rock-climbing accident, he’s been on a quest to design replacement limbs that feel like the real thing. It’s now possible to engineer light-weight custom ...

The price tag is orders of magnitude cheaper than most robots in its class, which can run into tens or even hundreds of thousands of dollars. Now China’s Unitree Robotics, best known for its nimble ...

There's a solid consensus among scientists on the question, according to a new survey. It’s easy to see why. Headlines such as “We’re probably not close” or “Nobody knows” aren’t very clickable. But ...

With their bright blue bases, yellow gears, and exposed circuit tops, the 3D-printed robots look like a child’s toys. Yet as a roughly two-dozen-member collective, they can flow around obstacles ...
