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
Brains of male and female mice recover differently from ketamine
<p>Nature, Published online: 31 July 2026; <a href="https://www.nature.com/articles/d41586-026-02356-0">doi:10.1038/d41586-026-02356-0</a></p>Specialized immune cells found in the brain, known as microglia, reach out to neurons in female mice that were given a dose of ketamine anaesthetic.
Show HN: Draco – A single-binary, self-hostable Firecrawl alternative in Rust
Scraping modern websites has become a massive headache. You basically have two choices: pay for an expensive API like Firecrawl/Browserbase, or run a fleet of headless Chrome instances that eat 1GB of RAM per page and still get blocked by Cloudflare.I built Draco to fix this. It’s a fast, single-binary web scraper written in Rust. You point it at a URL, and it spits out perfectly clean Markdown or structured JSON for LLMs.The secret sauce is that it doesn't just boot a browser for ever
Show HN: EvoChess – start with 8 pawns, evolve your army
This chess variant's theme is evolution. One morning in early 2016 I woke up with an idea:
what if chess were built around promotion? Eventually, this resulted
in the following game:It plays like chess, but you start with only pawns and a king.
Pawns can be promoted to bishops or knights, while
those minor pieces can be promoted to rooks.
Their promotion rights accumulate (every three pawn moves, pawn promotion
right; every three minor piece moves, minor piece to rook right).
Rooks are tra

Put together an extensive open source test suite for voice assistants. You can view it including current leaderboard at: https://git.cicero.sh/aquila/ha-voice-test-suite/Tests are reproduceable, with clear instructions on how to run them on your machine there.I only have a GPU with 4GB vRAM, hence only capable of testing the small LLMs like Qwen3 4B Instruct. Have Gemma 4 running right now, but it's insanely slow and probably another 24 - 48 hours before it finis
Ask HN: Who is firing? (August 2026)
As suggested in a comment(https://news.ycombinator.com/item?id=48765213) on my previous "Who is quitting?" post I figured I'd give a "who is firing" post a shot :)
Ask HN: Who is quitting? (August 2026)
Curious what people are getting up to! Following on from my previous post(https://news.ycombinator.com/item?id=48760048):<p><pre><code> 1. Why are you quitting?
2. What will you be doing? (Even if nothing!)</code></pre>
Show HN: Jotchi, a smart scratchpad for the busy brain
I love the idea of projects like Obsidian, but since I already have difficulty dealing with one brain, the idea of managing a second has never really worked for me.Since I'm always working on a bunch of stuff, I never really know if a particular piece of information will be important later or not. Ideally, I wanted a place that I could just dump notes into, and let the notepad itself organize everything in a clear and fast to navigate way.Ultimately, that lead to Jotchi, which became a sort
Show HN: Changed how I use agent harnesses
I’ve been using OpenCode for quite a while now, and I’m in love with it. The subscription cost of Claude Code or Codex doesn’t make much sense to me, so I prefer the free tier of OpenCode Zen!But for planning and drafting I do need capable models, which I grab from Zenmux or similar providers, and those are heavily rate-limited. I’d get most of the way through a task and hit a limit, which meant stopping, opening the config, swapping the provider, restarting, and picking the task back up from wh
Show HN: View GitHub PDFs in the browser, the easy way
Recently I've had to find and read specs for some obscure protocols and found quite a few PDFs on GitHub scattered across multiple repos. The only problem was that in order to view and search them I had to download and re-open them in the browser's PDF viewer.After a dozen or so PDFs it got really old so I decided to make this tool.How it works is you prefix any GitHub URL that points to a PDF file with "pdf" so instead of:"github.com/bogdannbv/pdfgithub.com&#x
Show HN: Autonomous daily AI news briefing blog
I like keeping myself in the loop of AI progress, and with an amount of things that are happening in the industry it has been quite a challenge.Yes there are plenty of AI newsletters and news-sources, including HN itself. However, all of those require significant time commitment. I was looking for something in a 5-minute-morning-briefing format, so I built it myself.Idea is pretty simple - every morning a pipeline is launched by cron on my raspberry pi. It crawls a few news sources (HN, reddit,
This hydrogen turbine turns controlled explosions into electricity
Scientists have successfully generated electricity with a hydrogen turbine that produces its own pressure through detonation waves instead of relying on a mechanical compressor. The breakthrough could unlock dramatically more efficient power systems for clean energy and future aviation.
Strange quantum experiment shows “negative time” is more than an illusion
Photons traveling through a cloud of atoms can emerge so early that they appear to have spent a negative amount of time inside. Researchers tested whether this was merely a misleading feature of the light pulse by making extremely weak measurements of the atoms. Surprisingly, the atoms confirmed the same negative dwell time. The finding does not break standard physics, but it reveals that one of quantum mechanics’ strangest effects is physically measurable.
Scientists just 3D printed one of the hardest metals on Earth
A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to more efficient manufacturing.
What does it mean to be ‘quantum’? A physicist explains the basics behind Einstein’s spooky actions at a distance
Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...

Alexander Rakhlin named director of the MIT Statistics and Data Science Center
Alexander “Sasha” Rakhlin PhD ’06, the Distinguished Professor in Data, Systems, and Society at the MIT Institute for Data, Systems, and Society (IDSS); and a professor of brain and cognitive sciences at MIT, has been named the next director of the MIT Statistics and Data Science Center (SDSC). Rakhlin succeeds Ankur Moitra, the Norbert Wiener Professor of Mathematics, associate director of the IDSS, and a faculty member in the MIT Department of Electrical Engineering and Com
Moonquakes could reveal hidden water beneath the lunar surface
Hidden moon ice may reveal itself through the way it bends and reflects vibrations from moonquakes. The technique could help astronauts locate vital water supplies and uncover clues about the origins of Earth’s oceans.
Scientists reveal the hidden force driving the universe’s hottest fluid
When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces. New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion. This acceleration may do far more than move the fluid, potentially changing its temperature-like behavior, influencing particle spins, and even reshaping how matter transitions betwee
