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

Fast-charging quantum battery built inside a quantum computer

An experiment with superconducting qubits opens the door to determining whether quantum devices could be less energetically costly if they are powered by quantum batteries

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

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: Local task classifier and dispatcher on RTX 3080

Hi HN, I am shubham a 3d artist who learned coding in college as an I.T. graduate know logics but not an expert as i just wanna try my hands on to aiSo i built Resilient Workflow Sentinel this is offline ai agent which classify urgency (Low,Medium and HIgh) and dispatches to the candidates based on availability 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.

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.
