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
Ultracold lithium atoms reveal a hidden struggle between quantum magnetic forces
What happens when three different kinds of particles interact, and each pair behaves differently?
Finally! Physicists Create an Exotic Quantum State of Matter That Works at Room Temperature
The laws of physics at the quantum level can break free from the standard confines of solids, liquids, and gases, and ...
China’s Tiangong space station sets a record with 9.7-picokelvin quantum gas
Researchers aboard Tiangong produced a rubidium cloud with a record-low equivalent temperature of 9. 7 picokelvin, based on ...
Show HN: Cross-device passkey auth on Android 9, synced with Bitwarden
I saw a colleague log in to a website on my laptop by scanning a FIDO QR code. I wanted to do the same, but couldn't find a way to use the passkeys stored in Bitwarden on my phone to log in.So I asked Claude to build me an app. Claude found the...
Show HN: emcee – macOS Stage Manager alternative
I am one of the (dozens!) of users of Stage Manager, but I don't like some of its UX choices. For example, it moves newly opened windows into a new stage, which breaks my focus.I spent some time trying to see if I could modify SkyLight and Windo...
Show HN: Build a PC in 3D in the Browser
I've been building this over the past few years. I left my job working on Google Earth to make a 3D PC builder. We have quite a few users so it's able to fund our team but I realized I never shared on HN!
Show HN: Recalc – Spreadsheet where cells can be Claude Code or Codex terminals
I built this because it was useful for me when building evals/benchmarks, and I decided to put it up for free for others. The goal was quite simple, make it easy to use a lead claude code / codex session in a panel on the side, while allowi...
Aaronson-Ambainis Conjecture proved! (By AI, of course)
We now, of course, live in age where longstanding open problems in quantum computing theory (and all theoretical computer science, and all math) are dropping like flies, to the extent that there’s no way I could possibly do a post on each and e...
Einstein's equations reveal how gravity could break, reconnect, and release energy
More than a century after Einstein revolutionized our understanding of gravity, scientists have uncovered a surprising new phenomenon hidden within his equations. Researchers at Columbia University and Universidad Adolfo Ibáñez have identified a theo...

A quantum computer with 22,593 qubits could crack the RSA encryption guarding bank accounts in about 3 days, a study estimates
A machine built from 22,593 cat qubits could factor an RSA-2048 key in roughly 3.14 days, according to a resource estimate ...
Not IonQ. Not D-Wave. This "Boring" Blue Chip Stock Is Quietly Leading in Quantum Computing
Quantum computing may be a game changer, and that’s sparked investors’ interest. Pure play companies and tech giants are ...
Ask HN: Does my iPad Air have a design bug in volume buttons?
I own an iPad Air from 2024 and every time when I press the upper (lower) volume button, it reduces (increases) volume, which, I feel, is quite counter-intuitive. I have owned this ipad for over two years now and I still press upper volume button (al...
Show HN: NLP capabilities of Opus, Astra, Argon measured by Codenames skills
Hello Show HN,I'm a college student, and I enjoy playing word games like Codenames, but it can be hard sometimes to find enough people to play when everyone is available, so I made an app that allows you to fill any seat with an AI teammate and...
Show HN: Sentient, Your Coding Agent Shouldn't Be a Black Box
after working quite rigorously for a few months with claude code, I found out that I was blindly approving permission requests for the sake of progressing my projects, this led me to realize that coding agents generate hundreds of commands underneath...
An unreleased Anthropic model just helped solve a major quantum-computing question
An unreleased Anthropic model helped solve a longstanding problem in quantum computing — another major math problem solved ...
Scientists achieve record-breaking low temperature on China's space station, paving the way for new physics experiments
Matter starts to behave differently at extremely low temperatures, creating conditions ideal for studying quantum physics and ...
