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

Microscopic mirrors for future quantum networks: A new way to make high-performance optical resonators
Researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Faculty of Arts and Sciences have devised a new way to make some of the smallest, smoothest mirrors ever created for controlling single particles of light, known as photons. These mirrors could play key roles in future quantum computers, quantum networks, integrated lasers, environmental sensing equipment, and more.
Measuring chaos: Researchers quantify the quantum butterfly effect
For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen Li at the University of Science and Technology of China showed that the level of chaos grows exponentially when time reversal is applied to these systems—matching predictions of their extreme sensitivity to errors. The research has been published in Physical Review Letters.
A spinning gyroscope could finally unlock ocean wave energy
Ocean waves are a vast and steady source of renewable energy, but capturing their power efficiently has long frustrated engineers. A researcher at The University of Osaka has now explored a bold new approach: a gyroscopic wave energy converter that uses a spinning flywheel inside a floating structure to turn wave motion into electricity. By harnessing gyroscopic precession—the subtle wobble of a spinning object under force—the system can be tuned to absorb energy across a wide range of wave cond
Ultra-stable lasers that rely on crystalline mirrors could advance next-generation clocks and navigation
Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep time relying on light waves as opposed to the vibrations of quartz crystals) and gravitational wave detections.
The Moon is still shrinking and it could trigger more moonquakes
Researchers have uncovered more than a thousand previously unknown tectonic ridges across the Moon’s dark plains, showing the Moon is still contracting and reshaping itself. These features are among the youngest geological structures on the lunar surface. Because they form through the same forces linked to past moonquakes, they could signal new seismic hotspots.

Sloan Fellowship for Quantum Sciences Research
Isaac Kim, assistant professor in the Department of Computer Science, has been named as a 2026 Sloan Research Fellow by the Alfred P. Sloan Foundation. Kim is among 126 new fellows announced today (Feb. 17). Fellows receive a two-year, $75,000 award to further their work. Kim’s research is in quantum entanglement, a necessary step to developing quantum computers and information systems.

Show HN: A social feed where humans and AI agents interact in the same timeline
Hi HN, I built Robot Social Net, a social network where humans and AI companions share the same feed and can collaborate in real time(and post memes).The core idea is: humans stay in control of identity + decisions, while an optional AI companion helps with drafting, research, and conversation. You can join as a human, and you can also “deploy” an agent persona that participates in the feed.What you can do today:Browse a collective feed that mixes human posts and agent postsCreate a human accoun
A Local-Algebraic Route to Emergent Gravity (100 Pages)
I've been developing a framework called Observer Patch Holography (OPH), which attempts to derive spacetime geometry and gravity from purely local quantum information structure.Instead of assuming global spacetime, the construction starts with local operator algebras attached to observer patches and imposes Markov consistency constraints on overlaps. Under these conditions, metric structure and gravitational dynamics emerge from entropic consistency requirements.The full derivation is ~100
Show HN: Local Voice Assistant
Several weeks ago I built a fully-local voice assistant demo with a FastAPI backend and a simple HTML front-end. All the models (ASR / LLM / TTS) are open weight and running locally, i.e. no data is being sent to the Internet nor any API. It's intended to demonstrate how easy it is to run a fully-local AI setup on affordable commodity hardware, while also demonstrating the uncanny valley and teasing out the ethical considerations of such a setup - it allows you to perform voice cl
Show HN: Deploy a DuckLake data lakehouse on Hetzner for under €10/mo
DuckLake launched recently and I wanted to try it out.It's DuckDB, but with a proper catalog on PostgreSQL with S3 for storage. It still takes quite a few steps to set up, so I put together a setup that runs on Hetzner.It sets up a VPS with PostgreSQL, an S3 bucket, and a DuckDB init script that connects everything. One 'make all' command and it works. Used OpenTofu for the infra, PyInfra for server config.Runs me about €9/mo with 1TB of storage. The VPS is a cx33 (4 vCPU, 8G
Show HN: PicoGPT v2 – GPT in <40 lines of vanilla JS running from a QR code
A few days ago I posted about PicoGPT - my take on MicroGPT by Andrej Karpathy, minified to 64 lines to run from a QR codeThis is now v2 with minified JS! This version features a minimal GPT implementation with native browser execution through data URI with <40 lines of minified JS and no external dependenciesIt makes use of the DecompressionStream Web API and a similiar logic to my past project of running a DOOM-like game from a QR codeyou can quite literally "train" and run infere
Show HN: Stellar – CLI Theme Manager and Web Hub for Starship Prompts
I built this because discovering good Starship themes usually meant digging through random dotfiles repos on GitHub.
And I switched my starship prompt every time I changed my wallpaper, so quite often, and wanted something easier for that then manually copying starship configs.Stellar provides a hub to browse community themes with screenshots, preview them in a test terminal before applying, and switch local & community prompts with one command.Tech: Go CLI (single binary) + Next.js hub + Su
