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

This ‘Machine Eye’ Could Give Robots Superhuman Reflexes

Running on a brain-like chip, the ‘eye’ could help robots and self-driving cars make split-second decisions. You’re driving in a winter storm at midnight. Icy rain smashes your windshield, immediately turning it into a sheet of frost. Your eyes dart across the highway, seeking any movement that could be wildlife, struggling vehicles, or highway responders trying to pass. Whether you find safe passage or meet catastrophe hinges on how fast you see and react.Even experienced drivers st

Show HN: I analyzed 120 films to help screenwriters test narrative structure

Almost 10 years ago, I used to host a film club in my office. A friend of mine was hosting one in the city and they needed a space.I had an openfloor office and that meant we clear the space, fire up the projector and can host the film club. They met between 9pm to 7am once a month, on a friday. Each meeting had 100-150 people attending.This went on for a few months - there was a curator assigned for each meet who would take a theme, and showcase films from the first film ever made in that genre

Show HN: LLM-use – cost-effective LLM orchestrator for agents

Hi HN, Built llm-use: a lightweight Python toolkit for efficient agent workflows with multiple LLMs. Core pattern: strong model (Claude/GPT-4o/big local) for planning + synthesis; cheap/local workers for parallel subtasks (research, scrape, summarize, extract…). Features: • Mix Anthropic, OpenAI, Ollama, llama.cpp • Smart router: cheap/local first, escalate only if needed (learned + heuristic) • Parallel workers (–max-workers) • Real scraping + cache (BS4 or Playwright) •

Atom-sized gates could transform DNA sequencing and neuromorphic computing

Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough opens new possibilities for single-molecule sensing, neuromorphic computing, and studying how matter behaves in spaces barely larger than atoms.

Quantum entanglement pushes optical clocks to new precision

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze at the German National Metrology Institute, hope their approach could help usher in a new generation of optical clocks—opening up new possibilities in precision experiments and metrology.

Why some tunes stick: Mathematical symmetry helps explain catchy melodies

Why do some melodies feel instantly right, balanced, memorable and satisfying, even if you have never heard them before? New research from the University of Waterloo suggests that more than creativity is at play.

AI breakthrough could replace rare earth magnets in electric vehicles

Scientists at the University of New Hampshire have unleashed artificial intelligence to dramatically speed up the hunt for next-generation magnetic materials. By building a massive, searchable database of 67,573 magnetic compounds — including 25 newly recognized materials that stay magnetic even at high temperatures — the team is opening the door to cheaper, more sustainable technologies.

New sodium ion battery stores twice the energy and desalinates seawater

A surprising breakthrough could help sodium-ion batteries rival lithium—and even turn seawater into drinking water. Scientists discovered that keeping water inside a key battery material, instead of removing it as traditionally done, dramatically boosts performance. The “wet” version stores nearly twice as much charge, charges faster, and remains stable for hundreds of cycles, placing it among the top-performing sodium battery materials ever reported.

Show HN: Q12 – A constraint-based 2D drawing tool

Q12 is a new web-based 2D parametric drawing tool built specifically for geometric problem solving, for playing interactive "what if" games with drawings, and for the design and optimization of mechanisms.Q12 has the usual set of drawing constraints found in other CAD tools (e.g. "lines are parallel") but also supports inequality constraints, area constraints, and arbitrary expressions between geometric quantities. We built Q12 to solve problems like those below, after findin
