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
This Strange Quantum “Dance” Could Rewrite Superconductivity
Scientists just revealed a hidden quantum “dance” that could reshape superconductivity. For the first time, scientists have ...
Sudden quantum jolts may not break adiabatic behavior after all
In thermodynamics, an "adiabatic process" is a system change that transfers no heat in or out of the system. Any and all ...
Physicists achieve first-ever 'quadsqueezing' quantum interaction
Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion. By ...
UI researchers’ work with quantum dots could create more efficient telecommunications
University of Iowa researchers have found that using quantum dots could yield more efficient telecommunications and may advance uses for quantum communications, the military, and in medicine, according to a new study.Ravitej Uppu, assistant professor in the Department of Physics and Astronomy,
The weirdness of quantum contextuality is not a bug – it’s a feature
Contextuality joins entanglement and magic states in "puzzle" of resources required for quantum error correction. (Courtesy: ...
Oxford scientists create rare quantum effect 100 times faster than expected
University of Oxford has achieved a milestone in quantum physics by demonstrating quadsqueezing, a complex fourth-order ...
What is quantum gravity? Scientists think it could explain the beginning of our universe
A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...
Weird Quantum Gadget Spits Out Chaotic ‘Sound Particles’
The device, described in a recent Physical Review Letters paper, generates phonons—a quantum mechanical description of ...
Your Consciousness Has a ‘Quantum Heartbeat.’ A Revolutionary New Device Could Unlock It, Scientists Say.
But rather than use them to find loose change, scientists are aiming terahertz waves at the brain itself. Their mission? To ...
Show HN: TapFi – Point your camera at handwritten WiFi credentials to connect
I've submitted this before but it got lost in the noise so hope it's ok to submit it again, I've added quite a few new features since last timeThis is a little app I built to deal with a pain point I find when travelling a lot, often you're in a cafe/pub or airbnb and the wifi details will be written down on a card or on a poster, this simply lets you take a picture of the details and it works out the SSID/Password (using Claude Sonnet) and connects youNew features
Show HN: I built the missing layer between email and DocuSign
Hi HN, I'm Pratik Garg. My back story is I built OneRequest because I kept running into the same problem at work and more than often personal life as well. Whenever I needed something from someone professionally like a document, a signed form, proof of something it always turned into a thread of emails, missed attachments and manual chasing and similar thing happened when someone wanted information from me and over a period, things were lost, scattered and ultimately gone.
I looked for a
Show HN: Reli – a sampling profiler and VM state inspector for PHP
I showed an earlier version of this here a bit over two years ago. Since then, Reli has grown a lot.<p>Reli is a sampling profiler and VM state inspector for PHP, written in PHP, that inspects running PHP processes from the outside.<p>In 0.12.0, tracing, memory analysis, monitoring, and runtime inspection all expanded quite a bit.<p>I would be especially interested in feedback on whether the memory-analysis, watch, and variable-inspection direction looks useful.

Hi HN,<p>I've been playing around with Cloudflare's Browser Run and Workers AI to create this funny "website vs website"-website.<p>Google's Gemma 4b model is actually quite good at vision.
Ask HN: How do you feel about AI assisted blogging?
How do you feel when you learn someone has been using AI heavily to help them write? Setting aside English as a second language.My knee-jerk is to find it disappointing. But maybe I’m missing some nuance. And I don’t have the same negative reaction to AI coding.But if you’re going to ask me to read a blog article, I don’t quite enjoy it when it’s not in your own words. I want to be in conversation with you, not you intermediated through an LLM.While I don’t particularly care about a bit of LLM s
Robots With Different Designs Can Now Share Skills
Abilities taught to one robot don’t usually work on another. With a new approach, it’s one and done. As robots move into the real world, they’ll need to become more adaptable. But right now, it’s hard to transfer skills from one machine to another. A new system makes this possible.One of the most popular ways to teach robots is to have a human show them what to do—either by physically guiding the robot’s joints, using remote control, or even drawing the desired motion.But those skill
Ask HN: Rant, Am I bad or is this a company with a poor tech culture?
Hey all, can you sanity check me? Am I a bad developer (always a possibility), or do I focus too much on unimportant things?I've got 13+ YoE and been working in big tech for about 4 years, joined an established start up (10 years old, profitable) a month ago, and wondering if I am out of touch after the meat-grinder that is competing for delivering "impact", stack ranking and so on.I don't know if I should stay at this company as I feel like I can't really do good work h
AI tackles one of math's most brutal problems: Inverse PDEs
Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for understanding the natural world.
Physicists achieve first-ever 'quadsqueezing' quantum interaction
Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion. By creating and controlling increasingly complex forms of "squeezing" – including a fourth-order effect known as quadsqueezing – the team has, for the first time, made previously unreachable quantum effects experimentally accessible.
Physicists have measured 'negative time' in the lab
As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands, but mostly dwelt with the nymph Calypso on her island. We can imagine that his wife, Penelope, would have asked him about that particular time. Odysseus might have replied, "It was nothing. In fact, it was less than nothing. Negative five years I dwelt with Calypso. How else could I have arrived home after only ten years? If you don't believe me, ask her."
