Elephant trunks and garden hoses hardly seem like inspirations for a miniature 3D bioprinter. Yet they’ve led scientists at McGill University to engineer the smallest reported bioprinting head to date ...

The first time I accepted that my grandpa was really aging was when I held his hand. His grip was strong as ever. But the skin on his hand was wafer thin and carried tell-tale signs of bruising across ...

AI is expanding our protein universe. Thanks to generative AI, it’s now possible to design proteins never before seen in nature at breakneck speed. Some are extremely complex; others can tag onto DNA ...

Quantum entanglement—once dismissed by Albert Einstein as “spooky action at a distance”—has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...

Imagine waking up in a hospital room. The last thing you remember is a terrible car crash. A doctor holds your hand and asks you to squeeze it. You try as hard as you can, but nothing happens—not even ...

Bioprinting holds the promise of producing tissues and organs on demand, but efforts have been held back by our inability to create the networks of blood vessels required to sustain them. Two ...

The code of life is simple. Four genetic letters arranged in triplets—called codons—encode amino acids. These are the building blocks of proteins, the machinery that powers life. But the genetic code ...

Designing drugs is a bit like playing with Polly Pocket. The vintage toy is a plastic clam shell that contains a multi-bedroom house, a skating rink, a disco dance floor, and other fun scenarios. Kids ...

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 ...

It’s easy to take safe drinking water for granted. In most developed countries, access to safe water takes a simple flip of a kitchen tap or a run to the grocery store. But over two billion people ...

"The work is a step toward building artificial intelligence models that learn continually—a long-standing goal of the field and something that will be crucial if machines are to ever more faithfully ...

At the age of 45, Casey Harrell lost his voice to amyotrophic lateral sclerosis (ALS). Also called Lou Gehrig’s disease, the disorder eats away at muscle-controlling nerves in the brain and spinal ...
