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 strange quantum property of tomorrow's insulator
Ultra-fast data transfer and superconductivity: Quantum materials offer significant technological prospects—if we can understand them at the atomic scale. A team from the University of Geneva (UNIGE), in collaboration with the University of Salerno, the Institute of Materials Science of Barcelona, and the National Research Council of Italy, has succeeded in observing the "quantum metric" in a topological insulator—a unique geometric property of these materials, which conduct electricity only on
Did the Linux memory management maintainer "just quit"?
I came across this breathlessly written article, the beginning of which I will reproduce below, so as to not give its author any more engagement:Title: "Linux Memory Had One Maintainer for 26 Years. He Just Quit. Now What?"Subtitle: "One person held the code that runs every Android phone, cloud server, and supercomputer for 26 years. On April 21, he posted one message and then was silent."Last non-paywalled sentence: "Two weeks later, at a developer summit in Zagreb, the
Show HN: Kakeibo – a simple budget tracking app for simple people
Hey HN!For the past few years I've been following the kakebo/kakeibo method to track my expenses and savings. The term might be a bit obscure, but it's really simple: plan your monthly spending based on your income and fixed expenses; track your expenses and categorise them in one of 4 categories (needs, wants, culture, unexpected); at the end of the month, reflect on your spending: look at aggregates by category, spot trends… overall, just be a bit more conscious about where you
Show HN: Raft in Rust
For quite sometime, I’ve wanted to give implementing the Raft consensus protocol a try. I first looked at MIT’s 6.5840 Distributed Systems labs as a way to do this but it is in Go and my Go skills have atrophied as well as I have been deeply investing time in Rust. The other option was PingCAPs approach (https://github.com/pingcap/talent-plan/blob/master/courses/d...) but I also wanted the ability to define my own types and RPC approach, so I decided to do
Show HN: Hyper, the self driving company brain
Hey HN -- I'm Shalin, one of the cofounders of Hyper.My cofounder Kanyes and I have been power users of a lot of second brain type software like Notion and Obsidian for years, and tried fine-tuning GPT-2 back in 2020 to solve this exact problem of giving AI access to all context of my life so it can do work for me more intelligently. We were too early then, and spent the next 4 years building robots at Matic. Earlier this year, we realized this was perhaps the right time to take a second cr
Bill Gates AI on AI (one month later)
# The Agentic Tidal Wave*To:* Executive Staff and Direct Reports
*From:* Bill Gates
*Date:* April 26, 2026Our vision for the last 20 years can be summarized in a succinct way. We saw that exponential improvements in cloud would make great software quite available. In the next 20 years the improvement in computer power will be outpaced by the exponential improvements in autonomous expert systems. Verifiable trust will be crucial to delivering the benefits of these advances.Most users of software
Show HN: Monkdev is a toolkit and methodology for coding with LLMs
I'm sure many people have some solutions similar to this but I've been using some variation of this since roughly the release of Opus 3 to get higher quality results. Like, significantly higher. So I decided to make it into a more structured package.Problem: bad decisions and short sighted solutions due to the LLM not having enough context before acting. They'd read one file, or a few segments of a set of files using a super conservative offset and limit, guess about the rest, app
Tell HN: Android Chrome deletes your browsing history silently
Under specific, but still indefensible circumstances, which I just learned is somehow the intended behavior.I don't think I quite understand what computing has become at this point. I keep encountering situations where the SWEs, who write and maintain software that I assumed to be trustworthy, decide that superficial considerations are more important than data integrity or user control of critical decisions. It keeps happening, so it's not a mistake or an oversight. Some of you genuine
Quantum teleportation carries microwave states at temperatures up to 4 K, beating classical limit
A growing number of quantum engineers worldwide have been trying to realize large-scale quantum networks, which consist of several connected quantum computers or devices that share information with each other. The successful realization of these networks could potentially pave the way for the realization of new high-speed and secure communication systems, or even of a quantum version of the internet.
Scientists break 30-year superconductivity record at normal pressure
Scientists at the University of Houston have shattered a long-standing superconductivity record, creating a material that can conduct electricity with zero resistance at the highest temperature ever achieved under normal pressure conditions. Their breakthrough pushes superconductivity to 151 Kelvin (minus 122°C), beating a record that stood for more than 30 years.
NASA’s Webb telescope discovers a planet where rock clouds vanish every night
A giant planet nearly 700 light-years away has a bizarre daily weather cycle where mineral clouds appear every morning and vanish by nightfall. Using the James Webb Space Telescope, astronomers discovered that WASP-94A b’s mornings are filled with clouds made of rock-like minerals, while its evenings are surprisingly clear. The finding gave scientists their clearest look yet into the planet’s atmosphere and revealed it’s far more Jupiter-like than previously believed.
NASA’s Fermi telescope reveals the power source behind monster supernovae
NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an exotic neutron star with unbelievably strong magnetic fields. The event, called SN 2017egm, erupted 440 million light-years away and may help explain why some supernovae become extraordinarily bright.
Photosynthetic Drops Soothe Dry Eyes With Sunlight
The drops, tested on mice, healed eye damage using light-sensitive particles—sourced from ordinary spinach. The unassuming vial of eye drops could easily belong on a pharmacy shelf. But swirling inside are microscopic bits of photosynthetic machinery made from plants. Within minutes of giving the drops to mice, their eyes gain an extraordinary ability beyond that of any mammal. Like a leaf, they can now harness the power of sunlight.Photosynthetic eyes sound like they’re straight out of science
Show HN: What story are you telling? (narrative archetypes tool)
Two weeks ago we posted our narrative archetypes framework here - thanks for the discussion. (We've published a whitepaper on the same on the website, for those who are interested)Curiosity seems to be getting the better of me still. The question is, if someone has a general premise for a story, can we suggest the narrative archetypes that best tell that story. For a lot of storytellers, that itself would give them plenty of ideas, and even a sense of direction to take the story into.We
Ten from MIT accept 2026 Fulbright awards
Ten MIT affiliates — including undergraduates, graduate students, and alumni — have accepted Fulbright grants to conduct research in countries across the world. Five other students declined their awards to pursue other opportunities, and another student is still deciding. In total, 16 of MIT’s 30 Fulbright applicants won awards this year. Funded by the U.S. Department of State with annual appropriations from Congress, the Fulbright U.S. Student Program offers year-long opportunities for Ame
