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

Immune-cell activity seems to play a key part in this spread.
Tumour–brain crosstalk restrains cancer immunity via a sensory–sympathetic axis

Show HN: ARIA – P2P distributed inference protocol for 1-bit LLMs on CPU
ARIA is a peer-to-peer protocol for running 1-bit quantized LLMs (ternary weights: -1, 0, +1) on ordinary CPUs. No GPU needed.
We benchmarked on a Ryzen 9: 89.65 t/s for 0.7B params, 36.94 t/s for 2.4B, 15.03 t/s for 8B — all on CPU, at ~28 mJ/token (99.5% less energy than GPU inference).
Key design choices: WebSocket-based P2P with pipeline parallelism for model sharding across nodes. Provenance ledger records every inference immutably. Proof of Useful Work replaces wasteful

Silicon Quantum Computing ("SQC"), a leader in quantum computing and quantum machine learning, today announced the launch of Quantum Twins, an application-specific quantum simulator designed to accelerate molecule and materials discovery. Built utilizing the company's atomic-scale semiconductor manufacturing process, Quantum Twins showcases the exceptional precision and already-achieved scalability of SQC's full-stack approach to quantum computing.
Electron-phonon 'surfing' could help stabilize quantum hardware, nanowire tests suggest
That low-frequency fuzz that can bedevil cellphone calls has to do with how electrons move through and interact in materials at the smallest scale. The electronic flicker noise is often caused by interruptions in the flow of electrons by various scattering processes in the metals that conduct them.
Glimpsing the quantum vacuum: Particle spin correlations offer insight into how visible matter emerges from 'nothing'
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key feature of virtual particles that exist only fleetingly in the quantum vacuum. The finding offers a new way to explore how the vacuum—once thought of as empty space—provides important ingredients needed to transform virtual "nothingness" into the matter that makes up our world.
