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

Ask HN: Researchers / PhDs interested in quantitative AutoResearch?

I'm looking for researchers and PhD students in statistics, learning theory, RL, open-endedness or self-driving labs.If you're interested, please email me at [email protected] with any note / interest / credential and we can take it from there!I am located in the Bay Area and recently had some very promising results. Looking to build this out now and get to know folks who might be interested in the same.I'm posting something vague for now. I'll share details wit

Show HN: Collection of Beauty–a walkable 3D museum of public-domain art

Hi HN,this is Collection of Beauty, a walkable, multi-floor 3D museum, based on a collection of art that I handpicked with 4000+ works.History: I've spent some time earlier this year just browsing Wikipedia public domain art for literally hours on end, downloading everything that I liked or appreciated, just asking myself do I find this beautiful on some level?The result is this... Well, not quite ^^In the end I had a large folder with a bunch of images in it that begged the question: can I

Show HN: Klad, a paint app your coding agent can drive (source-available)

I've been developing applications for a long time and have turned to game development as well lately. One of the things that frustrated me the most was that using AI agents for game development is very annoying in the art department. Your only options right now are to either use an image genAI model and roll the dice every time you want to make an edit, or have your agent draw with something like vectors.I was looking for an application that would allow me to ask an agent to make a first dr

Show HN: Spared – self-hosted Workers and Durable Objects for Rust apps

Hi HN,I wanted something like workerd + celld for untrusted Rust apps and couldn’t find anything that quite fit. That said, I got a lot of inspiration from workerd, celld, spin, and wasmcloud.spared (spare-dee) runs Rust apps + SQLite in isolated WASM sandboxes. It lets you run many apps per server, and by packaging SQLite inside the sandbox, you get better isolation than running it on the host. This opens the door to running untrusted code on a single machine.It's open source and runs on

Show HN: Daily Atlas, my geography quiz game where rarer answers score more

Hi everyone. I'm an AI Masters student (UvA Amsterdam), and quite the geography nerd, having spent countless hours on GeoGuessr. I wanted to make my own simple geography game, but with some (even small) AI component to it.The game consists of 6 geography-related questions (countries, capitals, flags, languages, borders, etc) every day, where the rarer your answer, the rarer your score (tiers are [common, uncommon, rare, ultra rare, legendary]). No account needed or anything.Something I didn

Ask HN: Would you launch a developer tool with only macOS support?

I'm building Headwig, a devtool that lets me run multiple agents on my app, isolate their changes across services, and test and iterate on each independently.I've built the macOS version and have been using it on my own webapp. It works particularly well for applications with multiple services.Now I'm thinking of launching it, but I'm debating one thing.Would you guys launch a developer tool with just macOS support, or wait until Windows and Linux are ready too?In the develop

Earth's fiery birth may have created hundreds of oceans' worth of water

Earth's water may have been born in the planet's fiery atmosphere rather than delivered by icy comets or asteroids. Scientists discovered that rocky pebbles reacting with hydrogen under extreme heat can produce water in minutes, potentially generating hundreds of oceans' worth during Earth's formation. The findings suggest that water may be a natural part of how rocky planets form, rather than something that must arrive from space.
