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: Fylepad – A minimal, tabbed Markdown notepad built with Rust
I built fylepad because I needed a dead-simple, local notepad that handles Markdown and tabs without the bloat of a full IDE or a browser-based app.Why use this?Instant: Built with Rust/Tauri, so it’s light on RAM.
No Cloud: Just a local tool for quick notes (with tables, code blocks etc) and diagrams (Mermaid/PlantUML).Tabs: I hate having 20 windows open; this keeps my scratchpads in one place.I'm curious—what's the one feature you feel is missing from your current "qui

Well i want an offline system like a person can trust with its sensitive data to stay completely locallyDid use ai to code for speeding and cutting labor.Its works on RTX 3080 system (t
Show HN: BioTradingArena – Benchmark for LLMs to predict biotech stock movements
Hi HN,My friend and I have been experimenting with using LLMs to reason about biotech stocks. Unlike many other sectors, Biotech trading is largely event-driven: FDA decisions, clinical trial readouts, safety updates, or changes in trial design can cause a stock to 3x in a single day (https://www.biotradingarena.com/cases/MDGL_2023-12-14_Resmet...).Interpreting these ‘catalysts,’ which comes in the form of a press release, usually requires analysts with previous expertise in

Scientists Want to Give ChatGPT an Inner Monologue to Improve Its ‘Thinking’
A new approach would help AI assess its own confidence, detect confusion, and decide when to think harder. Have you ever had the experience of rereading a sentence multiple times only to realize you still don’t understand it? As taught to scores of incoming college freshmen, when you realize you’re spinning your wheels, it’s time to change your approach.This process, becoming aware of something not working and then changing what you’re doing, is the essence of metacognition, or thinking about th
Quantum encryption method demonstrated at city-sized distances for the first time
Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to work on innovative new ways to encrypt information. One such method is quantum key distribution (QKD), a secure, quantum-based method in which eavesdropping attempts disrupt the quantum state, making unauthorized interception immediately detectable.
Three-way quantum correlations fade exponentially with distance at any temperature, study shows
The properties of a quantum material are driven by links between its electrons known as quantum correlations. A RIKEN researcher has shown mathematically that, at non-zero temperatures, these connections can only exist over very short distances when more than two particles are involved. This finding, now published in Physical Review X, sets a fundamental limit on just how "exotic" a quantum material can be under realistic, finite-temperature conditions.
Quantum Twins simulator unveils 15,000 controllable quantum dots for materials research
Researchers in Australia have unveiled the largest quantum simulation platform built to date, opening a new route to exploring the complex behavior of quantum materials at unprecedented scales.
Study reveals microscopic origins of surface noise limiting diamond quantum sensors
A new theoretical study led by researchers at the University of Chicago and Argonne National Laboratory has identified the microscopic mechanisms by which diamond surfaces affect the quantum coherence of nitrogen-vacancy (NV) centers—defects in diamond that underpin some of today's most sensitive quantum sensors. The study has appeared in Physical Review Materials and was selected to be an Editors' Suggestion paper.

Show HN: FIPS-Pad – The Notepad That Says "No"
This isn't your average "move fast and break things" text editor. It is an experiment in bureaucratic compliance as a feature.The "Serious" Part: It is a minimalist, offline, encrypted notepad that aligns with FIPS 140-2/140-3 standards. It doesn't just "use" encryption; it acts as a gatekeeper. It relies entirely on the operating system's validated cryptographic modules (Windows CNG, macOS CoreCrypto, Linux FIPS mode) and refuses to implement it
Ask HN: Is it just me or are most businesses insane?
I realize that its probably me, I'm the dumb one, but please bear with me and help me understand.
I've been recently looking for a new job as I am slowly viewing my previously functioning workplace accelerating towards a static dysfunction.I have spoken to quite a few companies and read a lot of recruitment boards in a rather sizable european city that ought to be filled with opportunities.
With tech-sovreignty on everyones lips I would expect some drive and excitement in the european
Show HN: Distr 2.0 – A year of learning how to ship to customer environments
A year ago, we launched Distr here to help software vendors manage customer deployments remotely. We had agents that pulled updates, a hub with a GUI, and a lot of assumptions about what on-prem deployment needed.It turned out things get messy when your software is running in places you can't simply SSH into.Over the last year, we’ve also helped modernize a lot of home-baked solutions: bash scripts that email when updates fail, Excel sheets nobody trusts to track customer versions, engineer
Show HN: Built AI Music Generator Using Claude 4.5 and 4.6
Hi everyone,I'm a YouTuber in San Francisco, and I’ve always struggled to find copyright-safe music for my videos. I wanted something quick and flexible, so I decided to build my own tool.In about a week, I put together Trymusic AI (https://trymusic.ai), a browser-based music generator. The main feature is the AI Song Generator, which can produce music from text descriptions or moods.I also added a few extra tools for convenience: Lyrics Generator, BPM Detector, MP3 to MIDI, Jingl
Scientists create smart synthetic skin that can hide images and change shape
Inspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a special printing technique that embeds digital instructions directly into the skin. Images and information can remain invisible until triggered by heat, liquids, or stretching.
Measuring time at the quantum level depends on material symmetry
EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for thousands of years, and the advent of quantum mechanics has not simplified the problem," says Professor Hugo Dil, a physicist at EPFL. "The central problem is the general role of time in quantum mechanics, and especially the timescale associated with a quantum transition."
A clever quantum trick brings practical quantum computers closer
Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new experiment shows how to perform quantum operations while continuously fixing errors, rather than pausing protection to compute. The team used a method called lattice surgery to split a protected qubit into two entangled ones without losing control. This breakthrough moves quantum machines closer to scaling up into something truly powerful.
