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 ...

The robots, each the size of a single cell, casually turn circles in a bath of water. Suddenly, their sensors detect a change: Parts of the bath are heating up. The microrobots halt their twirls and ...

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 ...

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 ...

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 ...

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 ...

When we write something to another person, over email or perhaps on social media, we may not state things directly, but our words may instead convey a latent meaning—an underlying subtext. We also ...

The tiny chips hitch a ride on immune cells to target inflammation in the brain. Scientists hope to kick off clinical trials within three years. From restoring movement and speech in people with ...

This year gave rise to an incredible mix of brain implants that can record, decode, and alter brain activity. It sounds like déjà vu—brain-machine interfaces also lived rent free in my head in last ...

My nephew couldn’t stop playing Minecraft when he was seven years old. One of the most popular games ever, Minecraft is an open world in which players build terrain and craft various items and tools.
