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: Agent-plan a CLI that automatically commits your agent's plans
After spending quite a bit of time using various coding agents and a workflow that uses markdown-based research/plan/handoff documents to hold context across sessions, I kept on running into an this question of how and where to store the generated markdown. The contents are usually useful for posterity and future projects in the same feature area. However, it felt burdensome for myself or reviewers to clutter up diffs with largeish markdown documents. This left me with a mess of uncomm
Do AI Agents Have Minds? A Philosopher Explains
To attribute agency to a computer program, we must be convinced no human is needed to stand behind its goals. In the past few months, partly autonomous or “agentic” artificial intelligence systems have racked up some astonishing feats, from hacking tech startups to solving some of the world’s most famous open mathematical questions.Agentic AI systems can work in “swarms” that communicate among themselves to complete tasks. The communications involved are often surprisingly human-like—which is sp
Heat drives electron orbital currents, revealing first experimental evidence of orbital Nernst effect
Researchers at National Taiwan University (NTU) have reported the first experimental evidence of heat-current-driven transverse accumulation of electrons' orbital angular momentum, a phenomenon known as the orbital Nernst effect. The study was recently published in Nature Communications.
What's going on with Xanadu Quantum stock Thursday?
Xanadu Quantum Technologies Ltd. XNDU stock fell in Thursday’s premarket trading after the quantum computing company reported ...
AMD expands PsiQuantum partnership to build quantum computing infrastructure
AMD expands its PsiQuantum partnership to co-design fault-tolerant quantum computing infrastructure and plans an undisclosed equity investment.
2 Quantum Computing Stocks That Could Help Set You Up for Life
IBM and Quantinuum are publicly arguing about how quantum computing will be won, and I think a lifetime investor should own both sides of that argument.
Catching rogue agents and preventing cyberattacks—quantum computing is about to have its ‘ChatGPT moment’
Oxford Quantum Circuits closed the biggest Series C fund raise for a quantum computing company in Europe. Its CEO Gerald Mullally says the technology is finally moving to the commercialization phase.
AMD plans to invest in PsiQuantum as they team up on quantum computers
PsiQuantum already uses AMD’s Versal FPGAs to develop its fault-tolerant quantum computer. These are chips that engineers can reprogram after manufacture. The new deal adds AMD’s Instinct GPUs, EPYC ...
Physicists say they've sidestepped a nearly 100-year-old quantum limit using hindsight
Artist’s concept of quantum foam, illustrating the fluctuations that quantum uncertainty implies at the smallest scales.
Asymmetric Quantum Super-Links Suffer Unexpected Fragility Under Amplitude Damping Noise
Analytical modeling of asymmetric three-qubit W-class states shows that concentrated super-links lose their initial entanglement advantage under amplitude damping noise.
Ask HN: Is there hope against slop?
Long time HNer here, mostly lurker. Developer turned agent steerer yada yada yada, you all know the story.I'm writing because I think we are missing something important in the discourse on slop. The realization that occured to me recently is that it is simply not possible for media (social, tranditional) platforms to ban and clean the mess of AI generated content — and for some reason I expected them to act on it solely on the sheer amount of nefarious, fraudolent and ill advised AI generat
Dark energy may have flipped from negative to positive 9.5 billion years ago
A mysterious force driving the expansion of the Universe may have undergone a dramatic reversal billions of years ago. Scientists exploring an overlooked branch of an alternative gravity theory discovered that dark energy could have switched from negative to positive roughly 9.5 billion years ago, potentially changing how we understand cosmic history.
Post Quantum Cryptography: What Leaders Need To Do Before Q-Day
Post quantum cryptography deadlines are arriving before quantum computers do. Why harvest now, decrypt later attacks, crypto inventories and AI make the work urgent now.
OpenAI’s ‘shepherds’ affirm blockbuster physics result
The company’s appointed team of experts has verified and released the groundbreaking AI-generated proof, which validates bedrock assumptions of the Standard Model of particle physics

IBM plans a 1,040-qubit quantum computer for 2027 using two Nighthawk r3 chips. Explore the technical hurdles, performance claims, and fault-tolerance goals.
Light-activated molecules in porous crystals show potential for quantum chemical sensing
An international research team led by Nobuhiro Yanai from the University of Tokyo and Michael R. Wasielewski from Northwestern University has created polarized radical pairs, molecules with unpaired electrons whose spins align, in metal–organic frameworks (MOFs), porous materials consisting of metal ions linked by organic molecules.
The Sun unleashed a monster storm. Earth may have made it worse
The massive solar storm that illuminated skies worldwide in May 2024 has uncovered an unexpected twist: Earth's own atmosphere may have helped make the storm so powerful. Satellite measurements revealed that roughly 85% of the charged particles fueling the disturbance originated from Earth's upper atmosphere rather than the solar wind. Scientists also detected an extraordinary 40% weakening of Earth's magnetic field high above the planet.
