Can AI cure cancer? 🧪

Hugging Face’s new $100 robotic arm wants to lend you a hand

On Monday, Hugging Face dropped the SO-101, a 3D-printable, camera-equipped robotic arm starting at $100. It can grab objects, move them around, and even nail tasks through reinforcement learning—the same AI technique used to train bots for games.

What’s new? The SO-101 upgrades last year’s SO-100 model with improved motors, faster assembly, and smarter balance, helping the arm support its own weight more easily.

What’s the cost? The DIY kit starts at $100, but fully assembled arms (or ones shipped to the US) can run closer to $500 depending on the supplier.

Craif’s AI tech could catch cancer earlier

Early detection saves lives. But blood tests and hospital screenings can be invasive, expensive, and easy to put off. Craif, a Japanese startup spun out of Nagoya University, is taking a different path to early diagnosis.

How it works: Craif’s platform uses AI to analyze a urine sample’s microRNA, molecules that are secreted by cancer cells even at the earliest stages. This means it could detect cancer when it’s most treatable.

Where things stand: Craif’s first product, miSignal, is already generating revenue in Japan, helping users detect risks for seven different cancers from the comfort of home. And the startup just raised $22 million for further research and expansion in the US.
