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

Quanta Computer ("Quanta"), a Fortune Global 500 manufacturer of advanced computing and cloud infrastructure, and Quantinuum (Nasdaq: QNT), a leading quantum computing company, today announced a collaborative development agreement to help establish an industrial foundation for the next era of quantum computing.
Horizon Quantum Builds Software Stack for the Race to Practical Quantum Computing
Horizon Quantum Computing Pte. (NASDAQ:HQ) is focusing on software intended to make quantum computers more usable for broader classes of applications, while maintaining a pre-revenue strategy until quantum systems can deliver measurable value in production environments, Chief Executive Officer and F
This bizarre star is defying physics—scientists stunned by unexplained quantum effect
Published in Nature, the study details observations of 1E 1547.0-5408, a magnetar formed by a massive star’s supernova ...
Knowledge: In quantum physics, more than one reality exists
Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is.

Show HN: Open Vibe Coded Elite – Harmless
I'm trying out a bit of an experiment - I've had Claude (and other models) building this for me: https://harmless.atomic14.com/It's an "Open Vibe Code" project - I won't be accepting any PRs, instead, open an issue https://github.com/atomic14/harmless/issues and I'll point claude at all the issues periodically and see what it does.The current game is very playable right now and has quite a few features. Push '?'
Show HN: A painting engine that lets you sculpt drawings (tech demo)
This is a playable tech demo. All painting software (Photoshop, Krita, etc.) rasterize your strokes as you work. This means the stroke is frozen forever. You may use some tools like perspective warp or liquefy but they are quite limited. The Soft Edge engine instead keeps a record of your strokes as data and rasterization happens on the fly, on each frame, like in a game engine. This lets you sculpt any property of your stroke.Right now you can paint the following targets: pressure (which makes
Show HN: LuaCAD – Parametric CAD Scripted in Lua
LuaCAD models solids in Lua rather than the OpenSCAD language, with operator
overloading for CSG (`a + b`, `a - b`, `a * b`).It ships with a CLI and a desktop app, including a preview area and a text editor.I've always been a big fan of OpenSCAD, but the SCAD language itself is unfortunately quite cobbled-together and is a very poorly designed programming language.LuaCAD takes all the good parts of OpenSCAD and combines them with one of the best scripting languages. It has now completely re
Show HN: Shoehorn, a library to quantize an LLM to fit your Mac's VRAM
I made this after seeing someone posit the idea online yesterday over lunch then spent some time refining it. So far it's pretty impressive IMO! Right now I am running Qwen3-30B-A3B on my 24gb unified memory m4 MacBook Pro at 50 tok/sec and this should definitely not be working for such a large model on my middling hardware.<p>Things are detailed in the README to get up and running and DESIGN.md has details on all the choices and such made along the way.
Biology Needs an AI Declaration
In the Leiden Declaration, mathematicians issued a treatise on how AI challenges their field. Others must do the same. This article was originally published on Undark. Read the original article.In June, a community of mostly mathematicians released the Leiden Declaration on Artificial Intelligence and Mathematics, an articulation of the values they hope to preserve as automated systems are integrated into the practice of developing mathematical proofs. This is necessary because some frontier AI
Scientists detect a nuclear reactor’s ghostly afterglow for the first time
Nuclear reactors may go dark, but their fuel continues producing a faint antineutrino “glow” long after shutdown. Researchers have now detected that residual signal for the first time, finding it closely matched predictions of radioactive decay inside the reactor and nearby spent-fuel pools. The breakthrough suggests antineutrino detectors could eventually monitor reactors even when they are offline.
World’s first superconducting quantum heat engine could help unlock massive quantum computers
A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate autonomously inside quantum computers, potentially eliminating huge numbers of costly, noise-producing microwave cables.
Quantum Latin squares cannot solve Euler's 36 officers problem without entanglement
Latin squares are arrangements of symbols in a grid in which every symbol appears exactly once in each row and column. These symbol arrangements, which were first studied more than three centuries ago, are now widely used to optimize experimental designs and develop secure cryptographic systems, puzzles or other complex combinatorial structures.

High-speed microscopy reveals electrical activity across the brain
Within the brain, neurons compute by generating electrical impulses. These signals travel throughout neurons, which are in turn connected in vast networks that control brain functions such as sensory perception, memory formation, and control of movement. In an advance that could help neuroscientists map those neural networks, leading to a better understanding of how neural activity underlies behavior and other brain functions, MIT engineers have invented a new microscope that can

DARPA Taps Qunnect to Strengthen the Reliability and Resilience of Quantum Networks
For decades, the distribution of quantum information has been confined to laboratory demonstrations because of the fragile nature of maintaining the fidelity of quantum entanglement across today's deployed telecommunications fiber. However, today, Qunnect is the first company in the world to anchor multiple quantum networks distributing quantum information across the telecom fiber spanning some of the world's busiest cities. Qunnect announced today the Defense Advanced Research Projects Agency h
