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

Mathematicians solve decades-old mystery about the hidden order in high-dimensional randomness

Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel prize winner—that first posed the problem didn't believe it would ever be solved. The solution provides insight into high-dimensional random structures that could potentially impact data science, machine learning and optimization.

AI scans 400,000 Reddit posts and finds hidden Ozempic side effects

By analyzing over 400,000 Reddit posts, researchers discovered that users of popular GLP-1 weight-loss drugs frequently discussed unexpected symptoms like menstrual irregularities, chills, and hot flashes. The findings suggest AI could turn social media into a powerful early-warning system for spotting side effects that clinical trials may miss.

Scientists may have found the source of the most powerful neutrino ever detected

A mysterious particle from deep space has scientists buzzing after the most energetic neutrino ever detected slammed through the Mediterranean Sea. Now, researchers think they may have identified the cosmic “culprits” behind it: blazars — supermassive black holes blasting jets of matter straight toward Earth.

Scientists discover atoms suddenly spinning backward in quantum experiment

Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, researchers triggered tiny atomic rotations inside a quantum material and found that the direction of rotation can unexpectedly flip as momentum is transferred. The strange reversal happens because of the crystal’s underlying symmetry, creating an almost impossible-sounding effect where two rotations combine

FutureThese Companies Say AI Is Reviving Entry-Level Jobs, Not Killing ThemLindsay Ellis | The Wall Street Journal ($)“In one of the biggest surveys on employers’ graduate hiring plans this year, nearly three times as many executives at companies using or exploring AI said they were increasing junior-level hiring in 2026 than cutting back. Those using AI most extensively were the most bullish, according to Strada Education Foundation, which surveyed about 1,500 employers.”Roboti

Quantum metasurface boosts terahertz detection sensitivity by exploiting in-plane photoelectric effect

Being able to see light and detect radiation is of utmost importance at any frequency. While this challenge has been solved in the visible range, radiation detectors in the far-infrared and terahertz regimes are either not sensitive, slow, or require bulky and expensive, often cryogenically cooled devices, which hinders practical applications.

Show HN: AI Guided 3D atomic orbital simulation

Hey folks, I've been working on this atomic orbital for the last few months. It's specifically designed to help you learn about quantum mechanics. Would love some feedback! <3 <3

Show HN: Darc – grep-like memory search tool for coding agents

Hi HN, I’m Junha Park. I've been experimenting with agent memory, especially how to make agents run more reliably on large tasks.I built Darc, an open-source shared memory search tool for coding agents, with a different approach from most agent memory systems we can see today. It is an index + (lexical) search tool over agent session history, rather than a managed memory system. No embeddings, no agent-aided consolidation, no injection hooks.How it works: Darc archives Codex / Claude C

Show HN: AI readiness toolkit: AI two-minute CODE maturity check

I've been using this for a while, and I thought others on HN might find it helpful. You can run it against a local repository, and it uses mostly non-AI tools to make a high-level assessment about how AI-native the repository is. This is all based on my own personal experience and is very much opinionated, but this has helped me grow my codebase without it collapsing under the weight of the AI coding biases that tend to happen unless you put the guard rails in place. This is me trying to st

Show HN: Smithereen – an early-Facebook-style Fediverse server

I quit in 2016 because the mismatch in values with the new management started driving me crazy.My core issue with Facebook, Twitter, Instagram, VKontakte, and other commercial, centralized social network services is that they all eventually drift away from "staying updated on your friends' lives" towards "getting world ne

Show HN: OpenRDMA-An Open Source FPGA-Based 400G RDMA-Like SmartNIC

We’ve been building an open-source FPGA-based 400G RDMA-like SmartNIC called OpenRDMA.The project includes RTL, drivers, and the FPGA data path implementation. Current hardware throughput has reached around 200Gbps so far.One interesting aspect has been verification: we’ve been using LLM-generated cocotb testbenches quite extensively. AI is still weak at SystemVerilog, but surprisingly useful for Python-based cocotb verification workflows.The entire stack is open-source: github.com/open-rdm

Show HN: Quit All, an iOS app with an SOS mode for cravings

I built Quit All, an iPhone app for breaking bad habits. The main idea is that most habit trackers help after relapse, but cravings happen before that. Quit All has an SOS mode with a timer, GIFs/prompts, streak tracking, relapse logging, savings, milestones, danger-time stats, and iOS widgets.
