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
Show HN: Vibesurfer – a token-efficient browser for AI agents, no Chromium/CDP
I grew tired of numerous Chrome/Playwright/Puppeteer skills and MCP plugins, which for me felt quite heavy and unstable.<p>So I built this to allow my agents to efficiently test and work with websites.
Show HN: Orchid – An AI Assistant
Hey HN! We're working on https://orchid.ai/, a proactive assistant that lives in your messages and needs zero setup / configuration.Our users are currently using Orchid in 3 main ways:1. Automations: Orchid can integrate with your tools via MCP and run tasks however often you need to. some cool examples we've seen include: daily email & calendar digests, NBA/F1/Soccer live updates, linear tasks reminders, and email organizing.2. One off tasks: Orchid c
Show HN: Skill Studio – mine, edit, and manage Agent Skills
We love agent skills and use it a lot in our company. For something meant to be distilling human expertise, the human interface is quite broken.<p>So we built the best human interface for skills and open sourced it so everyone can use it and contribute. Rust app available on Mac, Windows, and Linux.
Show HN: I visualized United States Chess Federation (USCF) ratings by state
I built this to explore public US Chess Federation data: active members, regular ratings, median ratings by state, rating distributions, and participation adjusted for population.USCF is the main organization for rated over-the-board chess tournaments in the U.S., so this is basically a snapshot of where organized tournament chess is most active.A few things that surprised me:Texas has the most active members, ahead of California and New York
Median rating varies quite a bit by state
Some smalle
Show HN: Let agents send/receive SMS using your old Android phone
While playing with agents I realised it might be quite handy if they could get access to OTP codes. And while at it, why not give them ability to send the SMS as well. Twillio is expensive and annoying to set up for my taste.I vibe coded simple Android app that can read/send SMS and simple relay server that acts as MCP for agents. Works surprisingly well and my old android phone from a drawer is doing something useful again.Feel free to use it if you find it useful. I put it just to a $5 vp
Show HN: Timestamp and provenance records for AI-assisted creative work
hey guys, I have been chronically online for quite a couple of months now, and honestly, a lot of content that keeps on going viral happens to be AI-assisted. This became more prominent when Seedance 2.0 came. AI work from Seedance 2.0 models are especially really good, that it is so hard to know if they were done by AI or a Hollywood-level production studio, they are that good! Cat videos, to now world cup anime videos are going viral on social media. Being that these videos are just all AI, a
Forked CozoDB to give agents cognitive primitives
CozoDB is an embedded relational-graph-vector database created by Ziyang Hu and the Cozo Project authors. It does Datalog, vector search (HNSW), and full-text search in a single embedded engine and was created with the vision to be the “Hippocampus for AI”. Unfortunately, the project went quiet after December 2024. KuzuDB, another embedded graph database with vector and full-text indexes similar to Cozo, was archived in October 2025.I decided to continue the vision by using Cozo to build a memor
Never trust a T-Rex
In 2024, at the same time as I was being called a genocide apologist, Zionist baby killer, etc. etc., I was also being hounded by my right-wing, pro-Israel readers, who demanded of me: knowing what you know, understanding what you understand, how could you possibly vote for Kamala Harris? How could you donate to Kamala’s campaign, urge your readers to vote for her, when she (like most Democrats) is obviously beholden to young left-wing activists, and young left-wing activists’ centr
Solar Beat Coal in US Electricity Mix for the First Time in May
Coal’s share has nearly halved over the last five years, while solar’s has more than doubled. But tariffs and permitting delays could slow growth in the years ahead. The transition away from fossil fuels is often framed as a long-term process, but recent data suggests the shift is already happening. Solar power has now crossed a major threshold in the US, surpassing coal in the electricity generation mix for the first time.Despite the Trump administration’s attempts to drive a coal revival

A new way to control tiny quantum light sources by twisting atomically thin layers of hexagonal boron nitride
In a paper published in Science Advances, researchers at the University of Technology Sydney (UTS) in collaboration with the University of Minnesota and Kyung Hee University have found a new way to control quantum light sources, which is one of the key elements needed before quantum technologies can be used reliably in real-world systems.

Tiny objects swimming in a superfluid of light move against the flow
Superfluids are intriguing states of matter in which particles behave like a giant collective wave, allowing them to flow without any friction. When this fluid flows past a fixed obstacle at a velocity below a specific threshold, it moves around it without slowing down or exerting any drag. Above this critical velocity, however, the superfluid state starts to break down, and the energy from the flow dissipates in the form of ripples and vortices in the fluid.
Scientists expected a black hole but found a neutrino factory powered by stars
A distant galaxy nicknamed Shadow Blaster may have revealed a surprising source of cosmic neutrinos: extreme star formation instead of a supermassive black hole. The discovery suggests that hidden, dust-filled starburst galaxies could account for a significant fraction of the Universe’s high-energy neutrinos.
Researchers found a Wordle strategy that wins 99% of the time
Researchers developed a Wordle-solving strategy that succeeds 99% of the time by focusing on information gain rather than likely answers. The method uses Shannon entropy to identify guesses that reveal the most about the hidden word. Each guess is designed to slash uncertainty and narrow the possibilities faster. The result significantly outperformed more traditional Wordle tactics.
Five phases of localization physics observed in a single quantum system
Physicists in China have observed five phases in localization physics within a single quantum system. Using an advanced photonic platform, the team, led by Yucheng Wang and Jingyun Fan at the Southern University of Science and Technology, Shenzhen, has demonstrated that localization physics is likely far richer than physicists anticipated. Their results have been published in Physical Review Letters.
Einstein’s “biggest blunder” may finally have an explanation
Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could explain why the universe isn’t expanding wildly fast. The study suggests that the very shape of space-time may protect the cosmological constant from disruptive quantum effects.
Black hole winds may be robbing giant galaxies of their future stars
Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected. Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw material needed to make new stars.
SpaceX wants to build AI data centers in space. Will it work?
The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power. Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth. Yet space remains a harsh and expensive place to operate, with major hurdles including cooling, maintenance, radiation exposure, and orbital debris.
