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: Sigma Runtime – Maintaining 100% Fact Integrity over 120 LLM Cycles

Context drift remains the primary barrier to deploying LLM agents in production-critical environments. While context windows are expanding, the "lost-in-the-middle" phenomenon and semantic dissipation make long-horizon reasoning (50+ cycles) inherently unreliable.Standard approaches (Sliding Windows or RAG) fail because they treat conversational history as either a flat string or a collection of isolated fragments.We’ve developed the Compression & Memory Topology (CMT) framework (p

Something supercharged Uranus when Voyager 2 flew past

Voyager 2’s flyby of Uranus in 1986 recorded radiation levels so extreme they baffled scientists for nearly 40 years. New research suggests the spacecraft caught Uranus during a rare solar wind event that flooded the planet’s radiation belts with extra energy. Similar storms have been seen near Earth, where they dramatically boost radiation levels. The discovery reshapes how scientists think about Uranus—and why it deserves another visit.

Dark matter could be masquerading as a black hole at the Milky Way’s core

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the center and the slower, graceful rotation of material far beyond. This dark matter structure would have a compact core that pulls on nearby stars like a black hole, surrounded by a broad halo shaping the galaxy’s outer motion.

How COVID and H1N1 swept through U.S. cities in just weeks

New simulations reveal that both H1N1 and COVID-19 spread across U.S. cities in a matter of weeks, often before officials realized what was happening. Major travel hubs helped drive rapid nationwide transmission, with air travel playing a bigger role than daily commuting. Unpredictable transmission patterns made real-time forecasting especially difficult. The study highlights why early detection systems are critical for slowing future pandemics.

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

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
