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: 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

Mars’ water mystery may have a simple ice answer

Scientists have found that ancient Martian lakes could have survived for decades despite freezing air temperatures. Using a newly adapted climate model, researchers showed that thin, seasonal ice could trap heat and protect liquid water beneath. These lakes may have gently melted and refrozen each year without ever freezing solid. The idea helps solve a long-standing mystery about how Mars shows so much evidence of water without signs of a warm climate.

This Robotic Hand Detaches and Skitters About Like Thing From ‘The Addams Family’

Each finger can bend backwards for ultra-flexible crawling and grasping. Here’s a party trick: Try opening a bottle of water using your thumb and pointer finger while holding it without spilling. It sounds simple, but the feat requires strength, dexterity, and coordination. Our hands have long inspired robotic mimics, but mechanical facsimiles still fall far short of their natural counterparts.To Aude Billard and colleagues at the Swiss Federal Institute of Technology, trying to faithfully recre

This paper-thin chip turns invisible light into a steerable beam

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus-control problem in light-shaping materials. This opens the door to tiny, highly efficient light sources integrated directly onto chips.

A superfluid freezes and breaks the rules of physics

Physicists have watched a quantum fluid do something once thought almost impossible: stop moving. In experiments with ultra-thin graphene, researchers observed a superfluid—normally defined by its endless, frictionless flow—freeze into a strange new state that looks solid yet still belongs to the quantum world. This long-sought phase, known as a supersolid, blends crystal-like order with superfluid behavior and has puzzled scientists for decades.

The Null Pointer Crisis: Running God-Mode Software on Legacy Hardware

We spend a lot of time discussing AI Alignment—how to ensure the machine’s values match ours. But I’d like to open a thread on a parallel issue that seems to be causing a "Kernel Panic" in the current generation (specifically Gen Z and Alpha): The Human Alignment Problem.I approach this not as a psychologist, but from a systems engineering perspective. If we look at the rising rates of anxiety, burnout, and suicide not as "illnesses" but as System Errors, a terrifying archite
