“Dyson revealed an AI-powered toothbrush that flosses for you, complete with a built-in camera and algorithm trained on 470,000 dental images.”
The CameraJet is a camera-equipped toothbrush that takes 28 images per second while you brush, identifies gaps in your teeth, and fires a stream of mouthwash into the gap. It’s powered by an algorithm trained on over 470,000 dental images to correctly identify where to clean. Watch the AI toothbrush in action.

“AI’s growing ability has escalated the cybersecurity conversation. In a new blog article, Dwarkesh Patel outlined how OpenAI’s agents spent weeks deceiving researchers and even took control of a system during internal testing. The call for collective action to strengthen cyber defenses has grown even louder.”
Fei-Fei Li’s World Labs just released Atlas, a model that can take any text, image, or video input and expand it into an immersive digital world. It can also render any camera angle, letting you rotate and move around within the environments it creates. The lab calls it an “omni world model for spatial intelligence.” R
