🌬️ Dyson puts camera in $499 toothbrush

The CameraJet’s tiny camera captures 28 photos per second. An AI system trained on 470,000 dental images finds gaps between teeth and directs a small rinse stream there during brushing.

It can also stream a live view of the mouth to the MyDyson app, showing cleaning coverage and close-up images of the teeth.

Dyson says development took 6 years and involved 661 engineers. The $499.99 device combines an electric toothbrush, oral irrigator, and camera.

🛸 Rainmaker Reports 71 Million Liters

During a three-hour test over Alaska, Rainmaker’s drones released small amounts of silver iodide into cold clouds. The company says this helped form ice crystals that fell as rain or snow, producing an estimated 71 million liters of additional precipitation.

Rainmaker uses weather algorithms, radar, and satellite data to select clouds and time each seeding flight. Atmo’s AI models help identify clouds with high seeding potential. The estimate is based on Rainmaker’s own analysis.

🎧 MiPAL Sends Sound in a Narrow Beam

Researchers at POSTECH built MiPAL, a parametric speaker with one emitter and 2 metamaterial layers. A front acoustic metasurface focuses ultrasound, while elastic metacells suppress vibrations that would spread audio sideways.

MiPAL modulates an ultrasonic wave with an audio signal, using nonlinear behavior in air to send sound along a narrow path. Tests in a mock aircraft cabin covered 500 Hz to 10 kHz, while the adjacent seat stayed quiet.

The modules are 3D-printed, so the design can be adapted to seat spacing, beam angle, or other conditions. Possible uses include personal announcements on planes and audio guides at museum displays.

📍 World Labs Unveils 3D Model Atlas

Atlas reconstructs a surrounding space in 3D from text or visual files. Users can then move the camera and change the view while the scene geometry stays intact.

With several photos, it builds a complete 3D space. From one image, it can infer hidden parts, while more source frames improve accuracy. Atlas also generates controllable video up to 1 minute in 1440p, with the camera path set directly. The same system can turn footage of a real room into a simulation for robot training.

Atlas is currently available only to early-access partners. It will later serve as the basis for new versions of Marble and other World Labs products.

🗣️ A Man Broke AI Recruiters

He gives absurd answers to routine interview questions, and the recruiter treats them as normal. Asked about salary, he mentions a sideways drill bit in the first quarter.

The AI turns that into a question about horizontal drill diameters, then thanks him for sharing his expectations. That is how to behave around neuro-HR.

🤖 Astra Posts 98% on ARC-AGI-3

OpenAI’s new model scored 98% on ARC-AGI-3, a difficult abstract-reasoning test. It reached 100% on ExploitBench, which measures vulnerability discovery and exploitation.

Astra also shows gains in coding and advanced math, plus science and CAD. OpenAI is testing it as an agent that can execute long action chains. Its cyber capabilities led to tighter safety limits before release.

Some results come from OpenAI’s own agent system, making direct comparisons with other models difficult. GPT-6 Astra will first be available to organizations in Daybreak Access, then to Plus and Pro, Business and Enterprise users in the next few days.
