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

What is a quantum computer's speed limit? Entanglement can provide an answer
Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex computational problems, with applications in everything from supply chain ...
Scientists Finally See Quantum Computer Failures as They Happen
A new ultra-fast monitoring system reveals that quantum computer qubits can change from stable to unstable in mere milliseconds.
Google quantum-proofs HTTPS by squeezing 15kB of data into 700-byte space
Google on Friday unveiled its plan for its Chrome browser to secure HTTPS certificates against quantum computer attacks without breaking the Internet.
Researchers develop encryption to protect against quantum computer hacks
The breakthrough addresses concerns that powerful quantum computers could eventually crack encryption standards to leave vulnerable financial systems, government communications, health data and media.

ChatGPT as a therapist? New study reveals serious ethical risks
As millions turn to ChatGPT and other AI chatbots for therapy-style advice, new research from Brown University raises a serious red flag: even when instructed to act like trained therapists, these systems routinely break core ethical standards of mental health care. In side-by-side evaluations with peer counselors and licensed psychologists, researchers uncovered 15 distinct ethical risks — from mishandling crisis situations and reinforcing harmful beliefs to showing biased responses and offerin
Superfluids emerge in 2D moiré crystal formed from time, study predicts
Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time without constantly heating up, breaking a physical rule known as time-translation symmetry.
Hidden oceans on icy moons may be boiling beneath the surface
Icy moons circling the outer planets may be far more dynamic—and explosive—than they appear. New research suggests that when heat from tidal forces melts their ice shells from below, the sudden drop in pressure could cause hidden oceans to boil beneath the surface. On smaller moons like Enceladus, Mimas, and Miranda, this process may help explain strange features such as Enceladus’ tiger stripes and Miranda’s towering cliffs.
A tiny twist creates giant magnetic skyrmions in 2D crystals
Twisting atomically thin magnetic layers does more than reshape their electronics—it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns stretching far beyond the expected moiré scale, reaching hundreds of nanometers. Even more surprising, their size doesn’t simply follow the twist pattern but peaks at a specific angle. This twist-controlled magnetism could pave the way for low-power spintronic devices built from geometry alone.
Scientists just turned light into a remote control for crystals
NYU researchers have found a way to use light to control how microscopic particles assemble into crystals, effectively turning illumination into a tool for shaping matter. By adding light-sensitive molecules to a liquid filled with tiny particles, they can adjust how strongly the particles attract or repel one another simply by changing the light’s intensity or pattern. This allows them to trigger crystals to form, dissolve, or even be reshaped in real time.

Show HN: ZcoreAI – Z-score regression channel screener
Hey HN,I built ZcoreAI, a quant stock scanner that applies
Donchian-Weighted regression channels to compute
Z-scores across multiple timeframes simultaneously.The idea: instead of eyeballing charts, you get a
matrix of Z-score values per ticker per timeframe
in one scan — so you can spot statistically
overbought/oversold signals across your watchlist
in seconds.How it works:
- Pick timeframes (1m to 1wk)
- Pick tickers (or use the preloaded free watchlist)
- Hit scan — regression chan
Show HN: E8-Matrix: open-source physical particle discovery platform
I’d like to share E8-Matrix - a open-source physical particle discovery platform (recent program paper titled “From a High-Symmetry Sector to Testable Observables: An E8-Motivated Projection Program”) and would greatly appreciate any constructive feedback from the community.The work outlines a top‑down computational framework that connects a high‑symmetry ⊇ E8 structure to 3+1D observables via an operational projection Π.Instead of ad‑hoc effective shifts, the goal is to trace predictions back
Show HN: ApplyGhost – Auto-apply to jobs with quality, not quantity
Hey HN,I'm a software engineer who spent 8 months job hunting last year. Applied to hundreds of jobs. Filled out the same forms over and over. Name, email, resume, cover letter, "how did you hear about us." You know the drill.I started building ApplyGhost out of frustration. Most auto-apply tools just blast your resume to 500 jobs and hope for the best. That never worked for me. I'd get interviews for roles I didn't even want.ApplyGhost takes a different approach: it rea
Aura-State: Formally Verified LLM State Machine Compiler
I noticed a pattern: every LLM framework today lets the AI manage state and do math. Then we wonder why pipelines hallucinate numbers and break at 3 AM.I took a different approach and built Aura-State, an open-source Python framework that compiles LLM workflows into formally verified state machines.Instead of hoping the AI figures it out, I brought in real algorithms from hardware verification and statistical learning:CTL Model Checking: the same technique used to verify flight control systems,
Show HN: Recall – Persistent Memory for Claude Code via MCP Hooks
Hi HN,A while back I posted about recall MCP - https://news.ycombinator.com/item?id=45516584
Since then I updated a series of times and received quite a good amount of positive response. I decided to take it a step further and make it an actual product. It has been a super interesting journey.I built Recall because I was spending 10+ minutes every Claude Code session re-explaining my project. Architecture, conventions, past decisions — all gone after a session restart or context c
Show HN: A machine-readable graph of truth claims, built on Git and Markdown
I've long been fascinated with deductive reasoning and wondered if it is possible to create comprehensive maps of human knowledge, starting from first principles.At it's core, Prime is just tooling to write, publish and explore a decentralized DAG of truth claims hosted on Github; a kind of infrastructure for rational thinking at scale.With the advent of LLMs I think this project might be more worthwhile than ever. I find LLMs can actually be quite "rational" if given specifi
