MIT engineers develop a magnetic transistor for more energy-efficient electronics

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

Show HN: Subatix – your local-first consulting team in an AI-workspace

Hello HN!We, a team of 2, built Subatix after one of us spent almost 6 years in big consulting and at certain point came to a thought like «90% of what consulting is usually data-analysis related, why not make smth so any business get same level of insights without externals and 6-figure+ checks and fast?!». Based the experience during every project everyone wants - fast answers from their data, but real ops/business data is messy, sensitive, and hard to outsource to generic AI tools due to

Show HN: A private, PQ-secure, infinitely scalable blockchain[fully open-source]

For the past few months, I’ve been working on a new Layer 1 blockchain designed to solve what I see as the fundamental trilemma in the space: achieving strong privacy, infinite scalability, and post-quantum security simultaneously. The result is NERV: a private-by-default, horizontally scalable blockchain that replaces Merkle trees with 512-byte neural state embeddings, proven inside Halo2 circuits and attested in hardware enclaves.
