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

New Algae Robots Swarm Like Locusts at the Flick of a Switch
Self-assembling swarms of microrobots could someday deliver drugs and pull toxins from water. For most of us, a locust swarm sounds like an utter nightmare. For roboticists, it’s inspiration.Nature abounds with creatures that cooperate with a “hive mind.” From bees gathering pollen to schools of sardines grouping to avoid predators, individuals seamlessly move together in ever-changing configurations. Roboticists inspired by these dynamics have designed microrobots—often no more than the width o
Physicists create hybrid light-matter particles that interact strongly enough to compute
Eighty years ago, Penn researchers J. Presper Eckert and John Mauchly launched the age of electronic computing by harnessing electrons to solve complex numerical problems with ENIAC, the world's first general-purpose electronic computer. Today, that same architecture still underlies general computing, but electrons are beginning to show their limits. Because they carry a charge, they lose energy as heat, encounter resistance as they move through materials, and become harder to manage as chips in
First-of-its-kind quantum science center coming to Illinois Wesleyan
Illinois Wesleyan University on Thursday announced a new interdisciplinary program focused on quantum science that it says will be the first of its kind in the U.S.
Quantum Q-Day could disrupt the world even sooner than AGI
Quantum Q-Day threatens encryption; organizations must prepare now.
A Strange Quantum Effect May Explain One of Biology’s Greatest Mysteries
Electron spin may subtly break the symmetry between mirror-image molecules, helping explain why biology chose one molecular hand.

Neutral-Atom Quantum: What Is It, And Why Infleqtion Stands Out
Infleqtion is one of the leaders in applying the neutral atom modality to quantum computing delivering room-temperature scalable quantum computing.

Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids ...
Show HN: Learn algebra together, no AI slop, no ads or freemium, no registration
I think the modern world increasingly demands technical literacy. I felt that myself, and I also realized I still had gaps in algebra from school.But every time I opened a textbook, I wanted to quit immediately. Algebra on paper feels static, opaque, and disconnected from intuition.I don’t think algebra was meant to live only on paper. It becomes much more beautiful on a screen, when you can interact with it directly, change things, and immediately see what happens.You stop memorizing steps and
Thoughts on Claude Code 2.1.139 Agent View and Background Sessions
Spent half a day trying Claude Code 2.1.139’s new Agent View and background sessions — useful, but still has quite a few rough edges.The first item in the 2.1.139 changelog released on 2026-05-11 was Added agent view (Research Preview). Interestingly, they even included a dedicated doc link in the changelog this time:
https://code.claude.com/docs/en/agent-viewNot sure how many people here have tried it yet. I spent a few hours with it today and found both some really nic
Show HN: Trailmaps.app – Mobile maps that match the trail
I ride mountain bikes, build trails, do a lot of trail mapping in OpenStreetMap, and make print maps of the trails. Accurate trail maps are near and dear to me. And one thing I've found with pretty much every online map is that they are quite generic as to how they color the lines illustrating the actual "trails" within a park or trail system. In person, mountain biking trails/routes tend to be marked with signs, often featuring a different color for each route. And there is
Show HN: QUptime, quorum based decentralized uptime tool
Hello HN!
I have been lurking for a while, first time poster.I spent quite some time looking for a lightweight, multi-node uptime tool, like uptime-kuma in its easy deployment, but didn't find anything that met my criteria, that being:- Decentralized alerting.- Free and open source.- Quorum & state management.So I cobbled together this tool, in all honesty this was written by me and Claude, and I do not want to give anyone the false impression this was made fully by me.I would love to h
Show HN: Mind Focus, an Android app for focus and attention recovery
I don't really know how to do this. I'm a Spanish solo dev and solo writer, and a long time ago I created an Android app for personal use, called Mind Focus, that has helped me work more focused and take back my attention.And now I've gotten up the nerve to share it because I think it can be useful to others.To that end, I've combined two things that have personally worked for me and are also backed by data:The Pomodoro technique (and time-boxing in general as a task manageme
NASA’s new AI space chip could let spacecraft think for themselves
NASA is testing a next-generation space computer chip that could give spacecraft the ability to operate far more independently in deep space. The radiation-hardened processor is showing performance levels hundreds of times beyond current spaceflight computers while surviving punishing tests designed to mimic the harsh conditions of space. The technology could enable AI-powered spacecraft, faster scientific discoveries, and smarter missions to the Moon and Mars.
Mars may have once had an ocean and this chaotic valley is a big clue
A colossal valley near Mars’s equator is revealing dramatic clues about the Red Planet’s watery and volcanic past. Stretching roughly 1,300 kilometers, Shalbatana Vallis was carved billions of years ago when enormous floods of groundwater burst onto the surface, gouging deep winding channels across the landscape. Today, the region is a striking mix of ancient flood scars, collapsed “chaotic terrain,” lava-smoothed plains, volcanic ash, and battered impact craters — all hinting at a Mars that may
NASA’s Roman Space Telescope could reveal millions of invisible neutron stars
NASA’s Roman Space Telescope could expose a vast hidden population of neutron stars lurking unseen across the Milky Way. By detecting subtle shifts in starlight caused by gravity, the mission may identify and even weigh isolated neutron stars that are otherwise impossible to see. Scientists hope the discoveries will reveal how these extreme objects are born and why they are blasted through space at incredible speeds.
Scientists “bottle the sun” with a liquid battery that stores solar energy
Scientists at UC Santa Barbara have created a remarkable new material that works like a “rechargeable solar battery,” storing sunlight inside tiny molecules and releasing it later as heat — even long after the sun goes down. Inspired by reversible changes found in DNA and photochromic sunglasses, the system captures solar energy without relying on bulky batteries or the electrical grid. The molecule can hold energy for years and packs more energy per kilogram than lithium-ion batteries.
Physicists Have Measured ‘Negative Time’ in the Lab
Photons traveling straight through a cloud of gas appear to exit, on average, before they enter. As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands, but mostly dwelt with the nymph Calypso on her island.We can imagine that his wife, Penelope, would have asked him about that particular time. Odysseus might have replied, “It was nothing. In fact, it was less than nothing. Negative five years I dwelt with Calypso. How else coul
