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

Multidimensional profiling of heterogeneity in supratentorial ependymomas

The brain of new productive forces: Quantum technology
Today, China is investing heavily in quantum technology as part of its future industries. From quantum computing to quantum communication, humanity is beginning to use the rules of the quantum world ...
New IIT Bombay test could unlock quantum gravity secrets
Researchers at IIT Bombay have proposed a new test, dynamical fidelity susceptibility (DFS), to measure the 'quantumness' of gravity, suggesting that conventional entanglement-based tests may be insufficient.
Diffusion LLM may make most of the AI engineering stack obsolete
I've been deep-diving into diffusion language models this week and I think this is the most underrated direction in AI right now.The core issue with autoregressive LLMs:Every major model today (GPT, Claude, Gemini) generates one token at a time, left to right. Each token depends on the previous one. This single architectural constraint has shaped the entire AI industry:- Models can't revise what they already wrote → we build chain-of-thought, reflection, and multi-pass reasoning to for
Ask HN: Does automatic multilingual support make sense for a launch platform?
With vibe coding tools, adding multilingual support has become surprisingly easy. If you ask a model to add languages like Spanish, Portuguese, German, or French, it can usually set up the i18n structure pretty quickly, even for projects with a lot of text.One thing I’ve noticed is that once a site is indexed by Google, traffic doesn’t always come mainly from the US. Sometimes a significant portion comes from other countries through search. But most launch platforms or directories are English-on
Show HN: Local-first firmware analyzer using WebAssembly
Hi HN,<p>I just wanted to share what I have been working on for the past few months: A firmware analyzer for embedded Linux systems that helps uncovering security issues running entirely in the browser.<p>This is a very early Alpha. It is going to be rough around the edges. But I think it provides quite a lot of value already.<p>So please go ahead and drop a firmware (only .tar rootfs archives for now) and try to break it :)
Ask HN: Is Starlink still being jammed in Iran?
There were quite a few articles on HN in the recent past about internet being blocked in Iran, and Starlink being jammed. Just wondering what the current situation with Starlink and/or other satellite internet providers.
Tell HN: Beware of Mac Studio Scams on eBay
The tell-tale signs seem obvious in retrospect, but even the best of us can be fooled sometimes:1. The lowest price, by quite a bit
2. An eBay "classified" ad, which doesn't support purchasing through eBay (why does eBay even offer this?)
3. Some sort of rug pull at the last minute, to make the payment non-refundable.I'll give a detailed story: I found a Mac Studio M3 Ultra for ~$500 less than the closest "Buy it Now" machine. Emailed the seller, which requires fill
Show HN: 2D RPG base game client recreated in modern HTML5 game engine with AI
When I was much younger, I used to play a Korean MMORPG called Helbreath, and I also hosted a bunch of private servers for it. I eventually moved on, but I always loved the game’s aesthetics, its 2D nature, and its atmosphere. That may just be nostalgia talking.The community maintained private server and client, which to my knowledge were based on leaked official files, were written in fairly archaic C++. If you’re interested in the original sources, I’ve included the main client and server file
Show HN: A fictional programmer's life, hour by hour – ask Claude via MCP
I generated 2 years of a programmer's life — every hour tracked. His job at a big tech company, a side project that takes off, gym sessions, dinners with his wife, kids, the moment he quits his job to go indie. 4,251 entries.
The CLI is a single binary (no dependencies) that includes a TUI time tracker and a built-in MCP server. Run rows mcp install --demo and you can start asking Claude about this guy's life in 5 minutes.Try things like:"When did he quit his job?"

Show HN: MIDI Visualizer
I wanted to make a music visualizer that would show all of the notes and show what chord is playing. To make the analysis easier and accurate I stuck to MIDI only input.The main presets are:
- Warp: A kaleidoscopic view
- Stars: Shows the notes spiral away
- Clock: Reveals the music analysis mechanisms
- Piano: The standard MIDI visualizer viewThe menu allows for the compositor layers to be mixed and matched so you can explore and experiment. I'd recommend trying the "Feedback&
3 Questions: On the future of AI and the mathematical and physical sciences
Curiosity-driven research has long sparked technological transformations. A century ago, curiosity about atoms led to quantum mechanics, and eventually the transistor at the heart of modern computing. Conversely, the steam engine was a practical breakthrough, but it took fundamental research in thermodynamics to fully harness its power. Today, artificial intelligence and science find themselves at a similar inflection point. The current AI revolution has been fueled by decades of research i
Stacked quantum materials enable precise spin control without external magnetic fields
Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge has been the ability to control these delicate quantum properties with sufficient precision for practical applications. By combining different quantum materials, researchers at Chalmers University of Technology have now taken a decisive step forward, achieving unprecedented control over spin phenom
Photonic 'ski jumps' efficiently beam light into free space
Photonic chips use light to process data instead of electricity, enabling faster communication speeds and greater bandwidth. Most of that light typically stays on the chip, trapped in optical wires, and is difficult to transmit to the outside world in an efficient manner.
Scientists revive activity in frozen mouse brains for the first time

Scalable quantum batteries can charge faster than their classical counterparts
Over the past decades, energy engineers have developed increasingly advanced battery technologies that can store more energy, charge faster and maintain their performance for longer. In recent years, some researchers have also started exploring the potential of quantum batteries, devices that can store energy leveraging quantum mechanical effects.
Watching quantum behavior in action: MagnetoARPES reveals time-reversal symmetry breaking in a kagome superconductor
Electron movement and structures described in quantum physics allow researchers to better understand how and why materials like superconductors behave as they do. Rice University researchers Jianwei Huang and Ming Yi have developed a new capability, magnetoARPES, building on angle-resolved photoemission spectroscopy (ARPES) that allows researchers to study quantum behaviors they have been unable to resolve using ARPES alone. The work has been published in Nature Physics.
