The German startup Magnotherm is pioneering a new type of cooling technology: Instead of compressing a refrigerant gas, as usual, their fridges use metals that heat up in magnetic fields and cool when the field is removed. This can effectively be used to move the heat from one location (eg inside the fridge) to another (outside the fridge).
The idea itself is not new, it goes back to the 19th century, but Magnotherm is the first to make the step to commercial use. Earlier this year, they announced that the German supermarket chain REWE will deploy their new fridges in 10 stores. The company says their system uses 15% less electricity and avoids harmful chemicals. The technology can in principle also be used for air conditioning, but so far no one has developed a prototype.

HOLY: OpenAI says its *unreleased* Astra model (GPT6?) produced ten advances on long-standing open problems across mathematics, quantum complexity and theoretical computer science.
Among them:
â The first explicit non-sofic group
â Connesâs rigidity conjecture disproved
â Quantum parallel repetition proved for general two-player entangled games
â Ehrhartâs volume conjecture proved
â The first improved general sphere-packing exponent since 1978
OpenAI says the core arguments were generated by Astra. The model then formalized the proofs in Lean, producing machine-checkable certificates alongside a 249-page manuscript.
The successful solution runs would cost only roughly $2,000 in tokens at Sol API rates.
Scientific reasoning is becoming a genuine model capability much much faster than most people expected.
I am so freaking hyped. Breakthroughs every day. The day before yesterday, an 80% price cut for Terra and Luna; yesterday, the DeepSeek 4 flash release with insane evaluations and prices. Today, more breakthroughs with an unreleased model.
I love it! OpenAI is on such a great run!
