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: Rejourney – Open-source revenue leak prediction for web and mobile apps
Hello there (General Kenobi's favorite way to start the conversation),I’m Rashid, a sophomore at UT Austin. I built Rejourney.co (https://rejourney.co/) to predict issues with your apps and websites before they happen, based on real user session recordings.Here is a silly video (with cats) on how it works: https://www.youtube.com/watch?v=Z95MDxBXMjkIt’s open source, and the post link is the github repo, but here it is again: https://github.com/re
Control of Spin Qubits at Near Absolute Zero Could Enable Million Qubit Quantum Computers
David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), ...
World's first superconducting quantum heat engine offers path to larger quantum computers

NASA's Perseverance just completed a marathon on Mars
NASA's Perseverance rover has reached an impressive new milestone on Mars, completing the equivalent of a full marathon by driving 26.2 miles (42.195 kilometers) across the Red Planet. It accomplished the feat in just five years and four months, reaching the distance on its 1,890th Martian day, less than half the time it took the previous record holder, NASA's Opportunity rover.
NASA selects four new Moon missions to build a permanent lunar base
NASA is ramping up its lunar ambitions by awarding nearly $600 million for four commercial Moon landings planned for late 2028. Each mission will carry the same trio of science instruments to improve lunar navigation, study dangerous dust kicked up during landings, and map the Moon's radiation environment. The agency also revealed plans for new rovers, communication satellites, and additional cargo missions as it lays the groundwork for a permanent Moon Base.
Alan Turing's biggest AI assumption may have been wrong
A new book claims AI has been built on a flawed assumption dating back to Alan Turing's famous 1950 paper. Peter J. Denning argues that the most important parts of human intelligence, including common sense, intuition, culture, and practical know-how, cannot be encoded into computers. He believes this makes true human-level AI impossible, regardless of how large language models become.
In a First, a Humanoid Robot Performed Live Surgery Under a Surgeon’s Control
The robot removed a pig’s gallbladder with standard surgical tools in an ordinary operating room. Watchers held their breath as the robot made its first incision. Hovering over its patient, an anesthetized pig, with a robotic assistant standing nearby, it navigated to the gallbladder and gently removed it.The operation marked the debut of humanoid robots in a standard surgical setting. The robot, named Surgie, wasn’t autonomous—it was controlled by an expert surgeon—but the study is
New dark matter theory could solve multiple cosmic mysteries at once
Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter clumps that bend light through gr
I built an artificial lifeform descended from you
Hi HN,Everyone is waiting for consciousness to emerge in AI, right?Then I thought, why wait? Why not transplant ourselves instead?I architected SelfEidolon as an alpha experiment in self-evolving artificial lifeforms.It is not an AI assistant.It is an artificial lifeform descended from you.The alpha is invite-code only and limited to the first 1,000 users.Only 10 Invite Codes have been publicly released by SelfEidolon.They are available in Discord.https://discord.gg/P646MFAxbbAfte
