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

Congrats to Bennett and Brassard on the Turing Award!
I’m on a spring break vacation-plus-lecture-tour with Dana and the kids in Mexico City this week, and wasn’t planning to blog, but I see that I need to make an exception. Charles Bennett and Gilles Brassard have won the Turing Award, for their seminal contributions to quantum computing and information including the BB84 quantum key distribution scheme. This is the first-ever Turing Award specifically for quantum stuff (though previous Turing Award winners, including Andy Yao, Lesli
Building trust in the future of quantum computing
Quantum computers could solve certain problems that would take traditional classical computers an impractically long time to solve. At the Japan Advanced Institute of Science and Technology (JAIST), researchers are now working to make these systems reliable and trustworthy.

Show HN: Fin-primitives Zero-panic, decimal-precise trading types for Rust
I couldn't find a Rust crate that gave me validated financial types backed by decimal arithmetic. Everything I found either used f64 (unacceptable for order books), panicked on bad input, or was a thin wrapper around a single indicator.fin-primitives provides:- Price and Quantity newtypes over rust_decimal::Decimal, validated at construction — an invalid Price literally can't exist at runtime
- L2 OrderBook with sequence validation and atomic rollback if a delta would produce an invert
Dark Matter as Gravitational Memory: A Causal Rail for Wave Function Collapse
What if dark matter is not a missing particle, but the gravitational memory of the Universe's past quantum collapses — and that memory helps shape what collapses next?
ETRI, demonstration of 8-photon qubit chip for quantum computation
A group of South Korean researchers has successfully developed an integrated quantum circuit chip using photons (light particles). This achievement is expected to enhance the global competitiveness of ...
A world‑first quantum battery charges faster when it gets bigger—but it's tiny and only lasts nanoseconds
You're late for an important appointment. Just as you are leaving your house, you realize your phone is flat. Imagine you could charge it almost instantly by exploiting the strange rules of quantum physics. That's the promise of quantum batteries.
Pursuing a passion for public health
MIT senior Srihitha Dasari never imagined she would be speaking in front of the United Nations about health care, technology, and the power of co-designing public health interventions in collaboration with impacted communities. But when she stepped up to the podium to speak about digital well-being and community-centered health care design, she carried with her more than research findings. She brought several years of experiential learning in public health environments, ranging from visitin
Quantum Cryptography Pioneers Win Turing Award
One afternoon in October 1979, Gilles Brassard was swimming outside a beachfront hotel in San Juan, Puerto Rico, when a stranger swam up to him and changed the course of his career. Without so much as an introduction, the man began describing a way to create currency that couldn’t be forged. The scheme was based on the laws of quantum physics — a subject Brassard, a computer scientist…Source
Microwave quantum network shows resilience against heat-related disturbances
Quantum communication systems are emerging solutions to transmit information between devices in a network leveraging quantum mechanical phenomena, such as entanglement. Entanglement is a quantum effect that entails a link between two or more particles that share a unified state even at a distance, so that measuring one instantly affects the other.
Brain circuit needed to incorporate new information may be linked to schizophrenia
One of the symptoms of schizophrenia is difficulty incorporating new information about the world. This can lead people with schizophrenia to struggle with making decisions and, eventually, to lose touch with reality.MIT neuroscientists have now identified a gene mutation that appears to give rise to this type of difficulty. In a study of mice, the researchers found that the mutated gene impairs the function of a brain circuit that is responsible for updating beliefs based on new input.This mutat
AI uses as much energy as Iceland but scientists aren’t worried
AI’s growing energy use sounds alarming, but its global climate impact may be far smaller than expected. Researchers found that while AI consumes huge amounts of electricity, it barely moves the needle on overall emissions. The real impact is more localized, especially around data centers. Meanwhile, AI could become a powerful tool for building greener technologies.
Even JWST can’t see through this planet’s massive haze
Kepler-51d is a giant, ultra-light “super-puff” planet wrapped in an unusually thick haze that’s blocking scientists from seeing what it’s made of. Observations from JWST revealed that this haze may be one of the largest ever detected, possibly stretching as wide as Earth itself. The planet’s low density and close orbit don’t match existing models of how gas giants form or survive. Now, researchers are left with more questions than answers about how such a strange world came to be.
AI-powered robot learns how to harvest tomatoes more efficiently
A new tomato-picking robot is learning to think before it acts. Instead of simply identifying ripe fruit, it predicts how easy each tomato will be to harvest and adjusts its approach accordingly. This smarter strategy boosted success rates to 81%, with the robot even switching angles when needed. The breakthrough could pave the way for farms where robots and humans work side by side.
MIT scientists finally see hidden quantum “jiggling” inside superconductors
MIT physicists have built a powerful new microscope that uses terahertz light to uncover hidden quantum motions inside superconductors. By compressing this normally unwieldy light into a tiny region, they were able to observe electrons moving together in a frictionless, wave-like state for the first time. This discovery opens a new window into how superconductors really work. It could also help drive future breakthroughs in high-speed wireless communication.
Scientists used 7,000 GPUs to simulate a tiny quantum chip in extreme detail
Researchers have pushed quantum chip design into a new era by simulating every physical detail before fabrication. Using a supercomputer with nearly 7,000 GPUs, they modeled how signals travel and interact inside an ultra-tiny chip. Unlike earlier “black box” approaches, this method captures real materials, layouts, and qubit behavior. The result is a powerful new way to spot problems early and build better quantum hardware faster.
