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
New research shows how 'hot electrons' can reshape metals in billionths of a second
Researchers at The University of Manchester have revealed how intense electronic excitation can trigger rapid structural changes in metals—without heating the atomic lattice—offering new insight into ultrafast materials behavior.
A way to read quantum bits faster and with less hardware
Quantum computers process information in a fundamentally different way from conventional computers, using quantum bits, or qubits, that can exist in multiple states at once. This could allow them to tackle problems beyond the reach of today's machines, from simulating new materials to optimizing complex systems.

NASA’s Psyche spacecraft aces Mars flyby capturing stunning timelapse video
NASA’s Psyche spacecraft aced its Mars flyby, using the planet’s gravity to speed toward its 2029 encounter with a metal-rich asteroid. The spacecraft tested its cameras, magnetometer, and particle-detecting instruments, capturing unusual views of Mars and measuring its magnetic environment. It also detected neutrons from the planet and spotted the tiny moons Phobos and Deimos.
Blazing like 10 billion suns: NASA’s Swift sees a wandering black hole devouring a star
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy. The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass.
Scientists create an “electron lighthouse” with laser light
Scientists have created an “electron lighthouse” that uses laser light to launch and steer electrons through a semiconductor without an applied electrical field. The quantum effect could eventually improve optical sensors, communications, imaging, and information storage.
Twisted laser light can tell mirror-image molecules apart
Scientists have created twisted laser beams that interact differently with right-handed and left-handed molecules, revealing their identity through the fragments they produce. The approach could provide a faster, simpler, and more sensitive way to analyze important molecules used in chemistry and pharmaceuticals.
‘Timer’ in the brain tracks sleep — and predicts awakening
<p>Nature, Published online: 27 July 2026; <a href="https://www.nature.com/articles/d41586-026-02294-x">doi:10.1038/d41586-026-02294-x</a></p>Chemical tags on proteins could provide a biomarker for sleep deprivation, mouse studies suggest.
Weak AI Regulation Could Be Worse Than None at All
A Cornell University study uses game theory to model how poorly designed AI regulation could backfire. Governments around the world are racing to regulate AI before it becomes too deeply embedded in society. But new research suggests poorly designed rules could make AI systems less safe than having no regulation at all.Regulatory disagreements in the US are leading to a patchwork of approaches as states take matters into their own hands. A key question is who should be responsible for the safety
Ask HN: Does the tech industry require deterministic ML training?
Hey, I was wondering whether the tech industries require deterministic ML training or is non-determinism acceptable?
As in, I know in case of LLMs, small float differences while training are generally tolerated as the model converges to similar quality regardless. But in more specific domains like medical device certification or autonomous vehicle safety validation or financial model auditing, I feel like whether two training runs producing bit identical models would be critical whether two trai
Ask HN: What's expected from an engineering manager or director now?
I just joined a 30-person AI startup in the Bay Area as Director of Engineering.Two non-coding founders (CEO and CTO) and a flat team. We have 2 PMs, 20 engineers. Every engineer is senior or staff level. They use Claude Code and AI agents etc quite well.What is my job in an environment like this? According to the CTO, I'm to improve the velocity and productivity while also balancing quality.Also, are there any Bay Area meetups or peer groups where engineering leaders are actually talking a
Ask HN: Are you using Rust on embedded devices yet? If not, why?
I started dabbling with ESP32-based MCUs from Waveshare with Rust, and I'm quite impressed with the state of things (esp-rs, embassy, probe-rs etc). Note that I haven't really done embedded in any other languages, so I don't really have anything to compare it with.One thing I did notice was that creating beautiful, interactive user interfaces on MCUs with displays is a little harder, libs like embedded-graphics don't look that great.This made me wonder, are people using Rust
Show HN: A browser-based video editor that renders videos directly with FFmpeg
Weave is a React app that provides a multi-track timeline editor to perform basic video edits like trimming, stitching, transitions, audio tracks etc. which maps directly to an FFmpeg command to render the video.I tried my best to have the React "video" preview closely replicate the FFmpeg lavfi filtergraph output, but naturally this is not perfect (especially replicating the `eq` filter using SVG filters is quite inaccurate).I've built this as a prototype for another project I&#x
Show HN: Dub Any Podcast in Your Language Using Local Models
Worth mentioning that the pipeline uses all open-weight models, though for the demo I used Kimi K3 for the translation piece due to the Kimi founder being interviewed.Have a listen for yourself: https://www.youtube.com/watch?v=92BQg2oozBgThe pipeline can be mostly run locally on an M-series Mac with at least 16 GB of RAM.The translation stage is the main quality constraint but local models are getting better and better. Could see a specialized 30B model be more than enough here.Di
Show HN: Dozenal – A Game of Spatial Arithmetic
Hello HN! We're Rory and Chris, and we've made a game called Dozenal[0], a grid-based number puzzle game where the objective is to use all the tiles on the board to create totals of 12 (hence the name).We think the mechanic is quite unique, although keen to hear if people know of similar games! You essentially drag tiles across the board, and the distance between two numbers decides the arithmetic operation when they connect to each other: zero spaces is addition, one space is subtract
Show HN: Sekey.sh – Manage SSH Keys in Apple Secure Enclave
Since I used MacBook with TouchID, I've been using SeKey (by Nicolas Trippar) to manage my SSH keys. It come with 2 advantages: the private keys are non-exportable and I will be asked for TouchID everytime a program needs SSH authentication. I'm happy with that setup because I won't worry about leaking my private keys and the authentication is quite convenience, until recently: the project is abandoned, no Apple Silicon build and macOS will end the x86 support soon. Then I found o
Show HN: Tilde Pay – Give your AI agent a bank account to pay for things
hey HN, I'm Daniel - I built Tilde Pay during a hackathon I took part in and couldn't stop working on it. It's an MCP server you can give your AI agent to buy things online with. It can process both x402, MPP payments & (hopefully soon), any card checkout form online.When you sign up, you get EUR and USD denominated bank account details to send deposits to which convert to USDC within a minute of receipt for your agent to spend in their own crypto wallet. You can then add the
Show HN: Watch 14-Byte AI "brains" attempt to solve a 2D maze (Its hard)
Hey HackerNews,I built this project over the last few weeks as a palette cleanser from a failed game launch.I wanted to learn a bit about AI/Neural-Networks and naively thought I could build a tiny maze-solving AI in a weekend with a 100% solve rate.Well - I couldn't, but I got pretty close. 14 Bytes total model size, and a 96.5% solve rate on unseen mazes. Trained across 46 phases experimenting with different ideas to improve the model (better performance, smaller size).Its quite fun
