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
Strange metal crystal reveals one of the strongest quantum signals ever measured
Scientists found one of the strongest signs of quantum entanglement ever seen, revealing unusual behavior inside a metal crystal.
Time may be an illusion derived from quantum entanglement
Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...
Ask HN: Favorite Online Magazines?
I regularly see posts asking where to find smallweb collections, mostly focused around personal blogs (single author). I'd like to similarly know what online magazine-style publications (multiple authors) folks enjoy. Quanta Magazine appears to be a fan favorite. What else is a common read for you?
Show HN: Claudete – Command a legion of Claude Code instances and shells
This is a weekend project I created due to my frustration with the classic terminal applications that have the issue that if I restart my Mac, then my Claude Code instances or my shell instances—are stopped, and I have to manually run them again.<p>Plus, they are not quite optimized for running multiple Claude Code instances, so I created this project to address this issue.
Ask HN: How do you handle QA at a startup with no QA team? Genuinely curious
Been doing QA for 19yrs, mostly at startups and still trying to figure out how are AI startups navigating the quality aspect nowadays, practically.
I'm also trying to productize my expertise and I see quite a lot of confusion among startups these days between: moving fast(whatever that means), quality, hitting PMF and/or growth.
Show HN: HyperPaste – a free, open-source clipboard manager for macOS
To me it always felt like clipboard history was one of the few things missing from macOS.There are already some excellent clipboard managers available, but after trying quite a few of them I kept coming back to the same goal: I wanted something that felt like it belonged on macOS. Fast, keyboard-first, private, and visually restrained.One thing I felt strongly about from the beginning was that it had to be open source. Clipboard managers have access to some of the most sensitive data we copy — p
Ask HN: Building a minimal to-do app based on Signal vs. Noise
Hey HN,My friend and I are building a very simple to-do app.The core idea isn't new: separating tasks into Signal (things that truly move your life or project forward) and Noise (work that just keeps you busy). The goal is simply to help you become more mindful about what you actually choose to do.It's easy to assume that being "busy" equals quality work. But honestly, after building side projects for a couple of years, I can assure you that's rarely the case, haha.We ha
Show HN: OpenSfM v1.0
OpenSfM v1.0 is here, and it's a big leap.The original OpenSfM (github.com/mapillary/opensfm), the Structure-from-Motion engine behind OpenDroneMap and WebODM, is no longer maintained. As former maintainers, we couldn't let it go. So we went back to work, and improved it on many fronts : faster, more scalable (a long standing issue was speed) and capable of taking you from raw photos to finished GIS deliverables in a single pipeline.We focused the v1.0 on aerial and GIS workf
Show HN: Turn documents into lip-synced video readers
I read a lot of pdfs and papers, and I bounce between "read it myself" and "listen to it". So for quite some time wanted to experiment with adding a lip-sync video. I wanted something that keeps the original page in front, narrates it and show exactly where word-by-word with the lip-sync video reading it - Closer to a YouTube explainer than an audiobook. I’d be interested in feedback on the interaction model, the usefulness of lip-synced presenters for reading, and where this
Show HN: Xenoeye – analyze network without AI using netflow, PostgreSQL, Grafana
Sorry for the slightly truncated title. It should have been "Network traffic analysis and monitoring without AI, using netflow-family protocols, PostgreSQL or ClickHouse, Grafana, and some scripts".In 2026, it might seem a bit presumptuous to announce AI-free software on HN.
But building a netflow analyzer manually is no less presumptuous!There are quite a few xFlow analyzers out there these days, and I'm constantly reminded of this. But I think there's always room for an alt
Millions of exploding stars could soon reveal dark energy's secrets
A new AI-powered framework could transform how astronomers measure the expansion of the Universe. By analyzing images of Type Ia supernovae and modeling their environments in unprecedented detail, researchers can estimate cosmic distances with near-spectroscopic accuracy. The technique is designed for the flood of data expected from the upcoming Vera C. Rubin Observatory and may greatly improve our understanding of dark energy.
Trump has big AI and quantum ambitions: this scientist’s job is to make them reality
<p>Nature, Published online: 29 June 2026; <a href="https://www.nature.com/articles/d41586-026-02023-4">doi:10.1038/d41586-026-02023-4</a></p>Darío Gil knows that researchers are sceptical of the massive US artificial-intelligence push — he’s asking them to keep an open mind.
Chinese supercomputer leapfrogs best US machines to be ranked world’s fastest
A Chinese system has become the world’s most powerful supercomputer, surpassing American machines for the first time since 2021.LineShine, installed at China’s National Supercomputing Center in Shenzhen, clinched the top spot in the 67thTOP500 ranking of the world’s most powerful supercomputers. The new system has already been used in a range of fields, giving developers another route to achieve supercomputing power.The machine, which came online in the first half of
Forget Code: AI Is Learning to Hack Society
Let loose on existing regulations, AI models sniffed out known loopholes—and exposed entirely new ones too. AI’s hacking skills are big news at the moment, but finding vulnerabilities in code may be the least of our worries. A new study suggests AI models can discover potentially damaging loopholes in the rules and regulations underpinning society.Modern AI systems are powerful optimizers. Give them a goal, and they’ll pursue it relentlessly, quickly discovering solutions that would take a
Graphene can hold multiple states of superconductivity, a new study finds
The ordinary graphite in pencil lead is proving to be surprisingly multifaceted at the microscale. In a study appearing today in the journal Nature, MIT researchers report that a certain microscopic structure found in natural graphite can host multiple superconducting states. Superconductivity is an electronic state of matter in which electrons pair up and glide through a material with zero resistance. While there are thousands of materials that are known to be superconductors, it is r

Physicists create a strange new quantum state called a fractional fermi sea
Researchers have shown that ultracold atoms can be driven into a strange new quantum state called a fractional Fermi sea, where particles organize themselves in unexpected ways. The discovery points to a new phase of matter that goes beyond established quantum theories and could expand the possibilities of quantum simulation.

Show HN: Better Graphs – Teach agents to stop making plain Matplotlib slop
https://github.com/temataro/better-graphsI want to teach good Matplotlib taste to agents and humans.
This repo contains:
1. Agent instructions + design motifs (Claude Code skills + a CLAUDE.md).
2. An online "blog" tutorial of the same skills, for people.
3. minerva.mplstyle, my opinionated sane matplotlib defaults.Inspired by Tufte's book: The Visual Display of Quantitative Information (a gift from my boss!), plus data-to-viz.com and the python-graph-gallery.
