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
Emery Brown, Daniel Hastings, and Douglas Lauffenburger named Institute Professors
A physician and neuroscientist who studies how anesthesia affects the brain; a leader in aerospace engineering, policy, and education; and the founding head of MIT’s Department of Biological Engineering have been awarded MIT’s highest faculty honor: the title of Institute Professor.With the appointments of Emery Brown, Daniel Hastings SM ’78, PhD ’80, and Douglas Lauffenburger, there are now 12 Institute Professors at MIT, along with 10 Institute Professors Emeriti.The appointments, which took e

An ordinary laptop solved a problem thought to require a quantum computer
A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing some calculations to run on a laptop. Their results matched both theoretical predictions and simulations performed with a quantum computer. The method could open new paths for exploring quantum dynamics and materials.

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: 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.
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.
