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

Key Chemistry Question Answered, No Quantum Computer Required

What Garnet Chan cares most about is basic science. He entered chemistry decades ago to understand some of the most consequential biochemical processes on Earth. But since then, he’s become a central figure in a different arena: the debate over whether quantum computers will have a decisive advantage over ordinary “classical” ones. Over the past decade, many quantum computing researchers have…Source

'Shoot for the moon?' Aim a bit lower, researchers say

How ambitious should you be? Folk wisdom offers conflicting advice: "Shoot for the moon," but also, "Don't let the perfect be the enemy of the good." A new study by researchers at the University of Wyoming, Stanford University and the University of Colorado-Boulder used a mathematical model to show that ambition lies in the middle—above average but finite.

Show HN: Liiists, a Markdown-first, iOS and CLI list app

This is the first app I've made that got all the way to "live." I started to learn this whole vibe-coding thing, and decided to publish/share because I quite like using it myself!Github: https://github.com/djt53/liiists iOS app: https://apps.apple.com/us/app/liiists/id6761671906It's a pretty simple list app, with three types of lists:- Lists (self explanatory) - Checklists (also pretty straightforward) - Logs (like lists,

Show HN: Legato – a Rust audio graph framework with a minimal DSL

I've been building Legato, a realtime audio graph framework for Rust. The idea is to sit somewhere between PureData/MaxMSP (graph-based, visual routing) and something like JUCE.The core of it is a minimal runtime and DSL for graph definitions. There are no loops, branching or evaluations. It's purely for wiring nodes together. If you want real logic, you write a custom node in Rust, register it, and drop it into the graph.This way, you can easily extend the framework with Rust, as

Show HN: Hm – a task runner with a Python DSL, growing into a CI/CD system

Hi HN! My name is Marko and I am working on a CI/CD system at harmont.dev, a CI/CD system that sucks slightly less. As I've been working on the cloud, I realized that the CLI might be generally useful as a task runner, even if you don't care for our CI/CD, and that's what I'm sharing here!Every CI system I've used at Tesla, Bun, and mesa.dev has had the same problems: stateless and slow (GHA), or stateful and horizontally unscalable (Jenkins), with YAML on

Ask HN: Burned out on AI and want to go part time

I’ve been in the industry for ten years and have been fortunate enough to build up enough savings to where I could work for substantially less than I make now.I’m so burned out on writing software and the never ending rat race that the industry has evolved into over the years that I’m at peace with quitting to do something part time so that I can focus on doing things just for myself that make me happy and give more of a sense of purpose that I feel is lacking in my life.Has anyone made a simila

A disk-first C++ vector engine

Hey all, I built brinicle, an in-process C++ vector engine with a python wrapper that consumes substantially less memory, while staying quite fast. On 1.2 million Amazon products, it achieves sub-ms P99 latency. It also supports lexical search, and hybrid search. In the hybrid search, we did not try to build two indexes and then fuse results, we create ONE HNSW Graph and utilize it for semantic, lexical, and hybrid search. benchmark comparisons: https://brinicle.bicardinal.com/ben

Show HN: Monochess – A chess variant with rule-bending action cards

Hey HN,A while back I saw a video[0] of people playing chess but using action cards to modify the rules mid-game (skip turns, reverse, draw 2, etc.). It looked incredibly chaotic and really fun to play, so I decided to actually build it as a playable online game. A small difference in Monochess is there's no need to call out a phrase if you just have one piece. I noticed while testing with the mrs. it became really annoying to keep doing this every move.That also gave me a really good reaso

Topological states emerge in quantum Hall-superconductor devices with multiple channels

Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of great interest for the development of quantum technologies, as they can yield desirable electronic properties that are robust against defects and disturbances.

'Atom Camera' maps laser light at nanoscale using a single ultracold atom

A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy technique called the Atom Camera, which uses a single ultracold atom at near absolute zero temperature trapped in an optical tweezer as a camera to visualize the intensity and polarization distributions of light at the nanometer (one-millionth of a millimeter) scale.

An AI Solution to an 80‑Year‑Old Problem Has Shocked Mathematicians

AI can rifle through enormous libraries of information to connect far-flung ideas—conceptual leaps remain a purely human skill. Last week, OpenAI shocked the mathematical community by revealing that one of its internal artificial intelligence models had found a counterexample to a famous conjecture made by legendary Hungarian mathematician Paul Erdős in 1946.The planar unit distance problem, or Erdős problem 90, has intrigued mathematicians for decades. The new result is no mere curiosity. Canad
