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

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

Show HN: LocalCoder – Tell it your hardware, get the exact local AI model to run

Hey HN — I built this after seeing the Qwen3-Coder threads here. Every thread had the same questions: which quant for my GPU? How much VRAM do I need? Ollama or llama.cpp? What context window can I actually use?LocalCoder answers all of that in one page. Pick your platform (Apple Silicon, NVIDIA, CPU), select your chip and memory, and it gives you:- The best model + quantization for your setup - Expected speed (tokens/sec) and context window - Copy-paste Ollama commands to get running in 60

Show HN: DeepBrainz-R1 – Reasoning-First Small Models for Agentic Systems

Hi HN,I’m releasing DeepBrainz-R1 — a family of reasoning-first Small Language Models (SLMs) designed for agentic systems in production.The core idea is simple: agentic systems don’t ask once — they reason repeatedly (tool calls, verification loops, retries, schema-constrained outputs). That changes reliability and cost requirements, where large chat-optimized LLMs often struggle.DeepBrainz-R1 models are post-trained to improve multi-step reasoning behavior, output stability, and robustness unde

Tuning topological superconductors into existence by adjusting the ratio of two elements

Today's most powerful computers hit a wall when tackling certain problems, from designing new drugs to cracking encryption codes. Error-free quantum computers promise to overcome those challenges, but building them requires materials with exotic properties of topological superconductors that are incredibly difficult to produce. Now, researchers at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) and West Virginia University have found a way to tune these material

A 'crazy' dice proof leads to a new understanding of a fundamental law of physics

Right now, molecules in the air are moving around you in chaotic and unpredictable ways. To make sense of such systems, physicists use a law known as the Boltzmann distribution, which, rather than describe exactly where each particle is, describes the chance of finding the system in any of its possible states. This allows them to make predictions about the whole system even though the individual particle motions are random. It's like rolling a single die: Any one roll is unpredictable, but if yo

Surgery for quantum bits: Bit-flip errors corrected during superconducting qubit operations

Quantum computers hold great promise for exciting applications in the future, but for now they keep presenting physicists and engineers with a series of challenges and conundrums. One of them relates to decoherence and the errors that result from it: bit flips and phase flips. Such errors mean that the logical unit of a quantum computer, the qubit, can suddenly and unpredictably change its state from "0" to "1," or that the relative phase of a superposition state can jump from positive to negati
