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

The unprecedented link between quantum physics and artificial intelligence
Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.
Quantum tech beats Russian satellite jamming in new arms race
U.S. government contractor Q-CTRL told Newsweek its quantum sensors would be deployed later this year as GPS jamming ...
World-first quantum-inspired optimizer now rides on a mobile robot
Engineers at Toshiba and MIRISE report embedding a quantum-inspired optimization system directly onto a mobile robot, ...
Dynamical freezing can protect quantum information for near-cosmic timescales
Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...
Physicist: I Believe You Can Enhance Your Consciousness—And Expand Your Perception Into a “Different Realm”
Thanks to advances in science, we’re now able to move beyond Bohm and Bohr’s theorizing; we can test their hypotheses through ...

ComputingBreaking Encryption With a Quantum Computer Just Got 10 Times EasierKarmela Padavic-Callaghan | New Scientist ($)“In 2019, Craig Gidney at Google Quantum AI co-authored a paper that reduced [the requirement to break RSA encryption] from 170 million to 20 million quantum bits, or qubits. And in 2025, Gidney devised a way to slash that number to less than a million qubits. Now, Paul Webster at Iceberg Quantum in Australia and his colleagues have managed to decrease the number even f
AI System – Is It Your "Cognitive Exoskeleton" or Simply Your Super-Fast Intern?
As it turned out, about "AI" there are two completely different understandings of the term "cognitive exoskeleton"...1. The Generalized-Abstract UnderstandingWell, it's clear that there is a generalized-abstract concept: you create text faster, translate faster, format faster, program faster, create reports and reviews faster...2. The More Concrete UnderstandingThere is a more concrete concept, when you for your typical mental activity create all kinds of ensembles from
Quantum Teleportation Breakthrough Sends 5 States at Once
A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.
Show HN: Idea-reality-MCP – MCP server that searches real data before you build
I kept wasting hours building things that already existed. Asked Claude to help me build a food delivery app — searched GitHub afterward, found 847 similar repos with 12 competitors over 1k stars. 6 hours wasted.So I built an MCP server that does the searching before you write code. It scans 5 real-time sources (GitHub, Hacker News, npm, PyPI, Product Hunt) and returns a quantified reality_signal (0-100) with actual evidence — repo counts, star counts, top competitors, and pivot suggestions.Exam
Ask HN: How to best use time before starting a SWE job?
I'm completing my fourth year in college and have accepted a SWE offer at quant firm, starting in the summer.I've been agonizing a lot over how to best spend my time. I've considered reading books (DDIA, for example), diving deeper into CS fields (college always felt a bit too shallow/meaningless to me), or learning more about C++/Rust/other languages. Clearly, I'm suffering a bit of analysis paralysis right now, and I would appreciate some advice on what to d
Show HN: QF STEM Ledger – Logging Structured Cognitive Work
I built a tool to log structured cognitive work, including proofs rebuilt from first principles, research notes drafted, and concepts properly mastered, after noticing that serious technical effort is rarely recorded in any structured way.<p>Curious to hear what HN thinks.
Tell HN: Coherence Doesn't Scale
Since quitting my software engineering job in November because my boss was pushing reckless use of AI, I've spent a ton of time trying to figure out what place AI actually has in the future economy.Thanks in large part to some amazing Substack authors[0,1] as well as the fact that agentic engineering is in the process of rediscovering everything that we have learned about human delegation, I finally had a breakthrough: coherence doesn't scale.A ton of energy has been & will be expe
Show HN: Focido – mobile app where real people motivate you to finish tasks
I've been struggling with my own to-do lists for years. Apps like Todoist or Habitica are great for reminders, but they never quite push me over the edge when motivation dips. So I built Focido: a social to-do app where you hire actual humans as motivators.Here's how it works. You post a task – say, "Run 5km tomorrow" or "Finish that report by Friday" – and pick a motivator from the marketplace. They check in via chat, nudge you with encouragement (or gentle guilt),
Show HN: JSON Maps – Describe Maps as JSON, Render Them with React and MapLibre
I have been building a library that lets you define interactive maps as a JSON object. Now the already existing Maplibre Spec is quite strong, but every time I needed to put a map together with markers, widgets, a legend, layer controls and a nice color palette, I'd end up writing a lot of boilerplate html, Even writing with AI it would mess up the layer management and working with different kind of formats, So I started building a layer on top. Its inspired by the json-render library by ve
