AI detectors are improving fast, Nature reports—but confidence scores are not verdicts. False positives can punish human writers, while rewriting tools help generated text slip through. Detection needs evidence, not theatre.

Europe now requires clear disclosure for deepfakes and certain AI-generated public-interest content. Good. If synthetic media can borrow reality’s face, the least it can do is wear a name tag.

This is insane 🫣. Nepal flooding filmed from a hill as broken glaciers cause chaos and destruction along the way.

Thomson Reuters built its own LLM, investing $40m to train a specialized model for legal, tax and news work. The company says early tests match frontier systems. The real AI moat may not be size. It may be trusted data.

Yayoi Kusama has died at 97. She turned hallucinations into dots, pumpkins and rooms that seemed infinite—and kept painting until her final days. Some artists decorate the world. She changed how it feels to stand inside it.

Nvidia reported $96.2bn in quarterly revenue—up 106% year over year—while data-centre sales reached $89bn. AI may still be searching for its killer app. The invoice has already found one.

SpaceXAI and Nvidia are designing an orbital AI computer around Vera Rubin hardware, with a first launch targeted for late 2027. Cooling data centres on Earth was complicated, so naturally we’re taking the problem to orbit.

China’s humanoid robot races have reached the “are we sure this is sport?” phase. Brilliant, awkward and slightly alarming. AI robots, humanoids, China tech, robot race. Video via @EHuanglu; original camera source is not yet confirmed.

omg.. if they were real athletes💀

Scientists built a tiny soft robot with artificial hairs that can steer blood flow, deliver drugs and capture rare cancer cells in samples. Promising research—not a treatment yet. Medicine keeps getting smaller while its ambitions grow.

XPENG’s IRON humanoid moves less like a lab demo and more like a product pitch. Its robotics unit just raised over $900m to push Physical AI toward mass production. Humanoid robots, Physical AI, robotics, China tech. Credit: XPENG.

In every move, there’s balance.
In every pause, there’s power.
Even robots can master the art of inner peace.
Join IRON — the Robot Kung Fu Master — and find your flow.

Meta agreed to pay up to $18bn to settle claims that Facebook and Instagram harmed children. The proposed deal adds youth time limits and parental controls. Apparently “move fast” eventually reaches the courtroom.
