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: Sentinel – open-source QA agent that reads your code before it clicks
Hey guys, we built something interesting that we're using for testing / QA with our own products and it's proving to be quite helpful.MIT License - https://github.com/Simbastack-hq/sentinelBlog announcement - https://blog.simbastack.com/announcing-sentinel/PS - Resubmitting this ShowHN since when I posted this yesterday, I completely forgot to make the repo visibility public.
Ask HN: What Is Happening to Messenger.com?
In ~February 2026 Facebook announced that messenger.com would not be available starting in April.> Starting April 2026, messenger.com will no longer be available for messaging. The Messenger desktop app is also no longer available. You can use facebook.com/messages to continue messaging on web.This was quite annoying because many of my people disable their Facebook accounts but continue to use Messenger and not being able to use it on the PC is quite silly.It's July 2026 and messeng
Show HN: BlazeRules – vectorized YAML rules for JSON, Kafka, and Arrow events
https://blazerules.devI initially wanted to make a sub-millisecond log parser in C++ but that blew into a embeddable decision engine, that can run YAML defined rules on incoming data.The rules are executed in a vectorized format on incoming data by reprojecting into a columnar format first, if it's not already. Depending on the payload size and rules complexity, the performance goes from 200K records/s to more than million records/sec, in terms of througput this would be
Ask HN: I've told everyone about my startup and its been harder than I thought
Im feeling immense pressure . I told everyone about this startup I've been working on, and Its been deteriorating my mental health more and more. Im running out of $$.I dont want to let everyone down. but I feel too tired to work, but im too tired to embarrass myself and quit. I dont want to quit on my mission.I feel so alone. I isolated myself from friends and family. I talked to thousands of my users. I dont know what to do.Would like some advice.
Kind of feeling doomful/dreadfulI
Show HN: Shikigami, run AI coding agents in parallel, each in a Git worktree
Hello all,I'm a software developer. Over the last few months more and more of my work has turned into using coding agents instead of typing the whole code myself. Usually a few claude sessions at once, sometimes codex, one per feature or per revealed bug.I ran them in a split terminal for a few weeks, and quickly spotted two main problems. The first is that I couldn't easily tell which agent was stuck waiting on me and which was still working, so I'd cycle through sessions and che

Quantum entanglement without transport: Leaky qubits offer route around noisy channels
The inevitable leakage of energy and information from a quantum system into its surrounding environment is the enemy of quantum technology. Now, researchers have demonstrated that it can be exploited to generate entanglement—the "resource" that quantum technologies use to perform tasks inaccessible to standard classical technologies.
New AI blood test predicts heart disease 15 years early
A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems. Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atrial fibrillation. Unlike genetic risk scores, which remain fixed throughout life, the system captures biological changes linked to a person’s current he
A tiny universe in a bottle reveals clues to the origins of life
Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space. By studying these laboratory samples, scientists can explore how organic chemistry unfolds around stars and how comets, asteroids and meteorites may have carried those ingredients to Earth.
A hand-manipulable crystal reveals large-scale quantum entanglement
A crystal several centimeters long has exhibited quantum behavior. Until now, this type of phenomenon was mainly studied with ...
Scientists identify the rare meteorite that killed the dinosaurs 66 million years ago
The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow.
NISQ and quantum supremacy did not fail
A week ago, a philosopher named Amit Hagar put out a preprint entitled The NISQ Trap: Eight Years of Demonstrations the Hardware was Built to Lose. Here’s the abstract:With a single clear exception, every NISQ-era flagship demonstration of ‘quantum advantage’ has, within eighteen months of its announcement, been classically reproduced, shown to rest on classically tractable structure, or closed by a simulability theorem. Six theoretical results from 2024 through April 2026 exp

How quantum circuits based on neutral atoms could find and fix errors
Quantum computers, devices that process information by leveraging the laws of quantum mechanics, have been found to outperform classical computers in some advanced tasks. Instead of storing information in the form of classical binary bits (i.e., 0 or 1), quantum computers rely on quantum bits (i.e., qubits), which can also exist in combinations of 0 and 1 states.
A shattered asteroid may have bombarded Earth 800 million years ago
A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and could have contributed to major climate and biological changes on Earth.
AI unlocks QLED recipe that doubles efficiency and boosts lifetime 40-fold
A technology has been developed that allows artificial intelligence to inversely determine the process conditions for quantum-dot light-emitting diode (QLED) devices—conditions that previously required extensive trial and error to identify.
NASA’s James Webb catches a supermassive black hole feeding
JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696. A vast filament appears to funnel material into an 800-light-year-wide spinning disk, where gas races around at up to 600 kilometers per second. The findings suggest black holes may recycle their own fuel by heating gas with jets and later drawing the cooled material back in.
Anthropic Says Chatbots Have What May Be a Key Feature of Consciousness. Are They Right?
When you interact with a large language model (LLM)—one of the systems behind chatbots such as ChatGPT and Claude—it can feel as though you are in contact with another conscious mind. But are you, really?Some prominent scientists, such as Geoff Hinton and Richard Dawkins, claim you are. But most experts remain skeptical, arguing that the impressive cognitive capacities of LLMs occur in the absence of consciousness.Recently, researchers at Anthropic, the company behind Claude, waded into this deb
