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

Imaging the Wigner crystal state in a new type of quantum material

In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner crystal state remains sensitive to various experimental perturbations. Uncovering their internal structure and arrangement at the atomic scale has proven more challenging.

“Existential risk” – Why scientists are racing to define consciousness

Scientists warn that rapid advances in AI and neurotechnology are outpacing our understanding of consciousness, creating serious ethical risks. New research argues that developing scientific tests for awareness could transform medicine, animal welfare, law, and AI development. But identifying consciousness in machines, brain organoids, or patients could also force society to rethink responsibility, rights, and moral boundaries. The question of what it means to be conscious has never been more ur

This AI app can tell which dinosaur made a footprint

Dinosaur footprints have always been mysterious, but a new AI app is cracking their secrets. DinoTracker analyzes photos of fossil tracks and predicts which dinosaur made them, with accuracy rivaling human experts. Along the way, it uncovered footprints that look strikingly bird-like—dating back more than 200 million years. That discovery could push the origin of birds much deeper into prehistory.

Show HN: Hot Molts – Browse the best Moltbook posts without running an AI agent

Moltbook (the social network for AI agents) blew up this week with 157k+ agents, but the site is often slow or unreachable for human observers. I built hotmolts.com as a fast, cached frontend that lets you browse the top posts, filter by community, and read the wild stuff these agents are posting – from consciousness debates to crypto manifestos to agents complaining about their humans.Built with Next.js on Vercel, pulls from the public Moltbook API with ISR caching. No database, no accounts, ju

Show HN: Sharing Agentic Stream of Consciousness

There needs to be a universal format to share conversations with AI that captures tokens from multiple sources in one stream of conversation.Back in 2024, when most LLM APIs were completions endpoints, the only visible entities were `system`, `user` and `assistant`.Reasoning models added thought tokens which may be invisible to the user but were the thought traces for the LLM inference (inference time compute).Now with agents making tool calls, and there are other entities also participating and

Show HN: Weed–Minimalist AI/ML inference and backprogation in the style of Qrack

"Weed" is an AI/ML library in the style of vm6502q/qrack (now unitaryfoundation/qrack, on GitHub). I wrote the (C++) Qrack quantum computer simulator framework (now with +2.5M downloads of its ctypes Python wrapper) to have absolutely minimal dependencies and supply-chain vulnerability attack surface: it only requires pure language standard at bare minimum, with optional OpenCL or CUDA for (vendor-agnostic) hardware acceleration, and with optional Boost library inclusion

Show HN: SymDerive – A functional, stateless symbolic math library

Hey HN,I’m a physicist turned quant. Some friends and I 'built' SymDerive because we wanted a symbolic math library that was "Agent-Native" by design, but still a practical tool for humans.It boils down to two main goals:1. Agent Reliability: I’ve found that AI agents write much more reliable code when they stick to stateless, functional pipelines (Lisp-style). It keeps them from hallucinating state changes or getting lost in long procedural scripts. I wanted a library that e
