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

AI-assisted math advance highlights gap between finding answers and judging their significance
AI models are good at finding answers to mathematical puzzles but are not as good at research judgment, according to theoretical computer scientists.
Show HN: What are vector embeddings? An interactive guide
Hey HN, I'm Abdur-Rahman Butler, a machine learning engineer at Isaacus.I made an interactive write-up that walks you through the A to Z of vector embeddings, inspired by Brendan Bycroft's incredible interactive LLM visualisation guide (see...
Ask HN: Many SWEngs out there are considering re-training
Question is what it says on the tin. I've been mulling over the state of the industry and where I believe it to be going, and while I believe there will still be a role for us SWEng's in the future, I believe there will be a need for far fe...
Show HN: Markdown to Doc in a Click
Everything is markdown now thanks to AI agents, which is honestly quite convenient for all things development, but once in a while you might want to share markdown with your non-technical friends, so what do you do then?MD2Doc of course! It was anoth...
Show HN: Geneva, a Rust FFmpeg CLI alternative with HTML/CSS graphics
I built this for my own use case, and I think other people could benefit from it.It's essentially a Rust rewrite of the ffmpeg CLI command, but with a modern API and good defaults + a native HTML/CSS composition engine that's been fine...
Show HN: Approximatr: The daily game of spatial intuition
Approximatr uses your built-in ability to gauge sizes, distances, alignments, angles etc to see how good your eyes are!I've been building this for a few months, and it's been fun discovering what types of puzzles humans are good at, and ter...
Show HN: Merlin, Run Your Claude Code and Codex from Slack, Linear and GitHub
Hi HN, I built Merlin to let you use your own Claude Code and Codex subscription from Slack, Linear, and GitHub.There is a desktop app for macOS and Windows, and a CLI daemon for Linux. When someone mentions Merlin in a Slack thread or Linear issue c...
IBM executive warns of risk of quantum computing hacks
Organizations are unprepared for the risks posed by quantum computing, IBM's Europe and Africa vice president Alessandro Curioni told AFP Wednesday, referring to the high-speed technology that could crack security encryptions and enable large-scale c...
Software advance brings complex quantum simulations to standard computers
A major software advance could aid the creation of bigger, more reliable quantum computers, a study suggests. Researchers have developed an algorithm that enables off-the-shelf computers to run quantum simulations previously only possible using the w...
A tiny magnetic whirlpool could point to a new kind of ultra-efficient memory
Every time a computer stores or erases information, it uses energy. The amount is tiny for a single operation, but those operations happen billions of times every second. For decades, scientists have wondered just how little energy a memory device co...
From spin wave to superconducting circuit: A one-way street for quantum information
Quantum information systems could one day shape everyday life through faster computing, sharper sensing and more secure communication. A new result from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Illinois...
