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
Scientists revive activity in frozen mouse brains for the first time

Scalable quantum batteries can charge faster than their classical counterparts
Over the past decades, energy engineers have developed increasingly advanced battery technologies that can store more energy, charge faster and maintain their performance for longer. In recent years, some researchers have also started exploring the potential of quantum batteries, devices that can store energy leveraging quantum mechanical effects.
Watching quantum behavior in action: MagnetoARPES reveals time-reversal symmetry breaking in a kagome superconductor
Electron movement and structures described in quantum physics allow researchers to better understand how and why materials like superconductors behave as they do. Rice University researchers Jianwei Huang and Ming Yi have developed a new capability, magnetoARPES, building on angle-resolved photoemission spectroscopy (ARPES) that allows researchers to study quantum behaviors they have been unable to resolve using ARPES alone. The work has been published in Nature Physics.

The 19th-century mathematical clue that led to quantum mechanics
More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While studying the paths of light rays and moving objects, Hamilton noticed a striking mathematical similarity between them and used it to develop a powerful new framework for mechanics. At the time, it seemed like a clever analogy—but decades later, as scientists uncovered the strange wave-particle nature of l
In a First, Researchers Use Stem Cells and Surgery to Treat Spina Bifida in the Womb
The study focused on safety, but the results offer hope the approach could give kids a chance to walk. Michelle Johnson was 20 weeks into her pregnancy when she learned her unborn son had spina bifida. Because his spine hadn’t fully sealed, the spinal cord was left protruding from a gaping hole. Without surgery, he would face a lifetime of disabilities.So she jumped at the chance to enroll in a small experimental trial for the condition at the University of California, Davis. The treatment combi
Remarks at UT on the Pentagon/Anthropic situation
Last Thursday, my friend and colleague Sam Baker, in UT Austin’s English department, convened an “emergency panel” here about the developing Pentagon/Anthropic situation, and asked me to speak at it. Even though the situation has continued to develop since then, I thought my prepared remarks for the panel might be of interest. At the bottom, I include a few additional thoughts.Hi! I’m Scott Aaronson! I teach CS here at UT. While my background is in quantum computing,
Scientists turn scrap car aluminum into high-performance metal for new vehicles
Scientists at Oak Ridge National Laboratory have created a new aluminum alloy called RidgeAlloy that can turn contaminated car-body scrap into strong structural vehicle parts. Normally, impurities introduced during recycling make this scrap unsuitable for high-performance applications. RidgeAlloy overcomes that challenge, enabling recycled aluminum to meet the strength and durability standards required for modern vehicles. The technology could slash energy use, reduce imports, and unlock a huge
Ultrafast computing: Light-driven logic tops 10 terahertz in WS₂
The future for our computers will literally be at the speed of light. Extremely short light pulses can perform ultrafast logical operations: these are the findings of a study recently published in the journal Nature Photonics. The study represents an important step toward developing a new generation of information processing technologies, potentially hundreds of times faster than what we have at present.
Chemical shifts help track molecules breaking apart in real time
When molecules fall apart, their electric charge doesn't stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small molecule fluoromethane (CH₃F). It was the first time that the Small Quantum Systems (SQS) instrument at European XFEL could deliver detailed insights into transient states during chemical reactions. The research is published in the journal Physical Review X.
Unexpected magnetic response in gold and silver atomic contacts contradicts previous theoretical predictions
Researchers from the Department of Physics and the University Institute of Materials at the University of Alicante (UA) and the Low Temperature and High Magnetic Field Laboratory at the Autonomous University of Madrid (UAM) have succeeded in measuring, for the first time, the electrical conductance of gold and silver atomic contacts subjected to extreme magnetic fields of up to 20 teslas, an intensity equivalent to 400,000 times Earth's magnetic field.
How Joseph Paradiso’s sensing innovations bridge the arts, medicine, and ecology
Joseph Paradiso thinks that the most engaging research questions usually span disciplines. Paradiso was trained as a physicist and completed his PhD in experimental high-energy physics at MIT in 1981. His father was a photographer and filmmaker working at MIT, MIT Lincoln Laboratory, and the MITRE Corporation, so he grew up in a house where artists, scientists, and engineers regularly gathered and interesting music was always playing. That mix of influences led him to the MIT Medi
Student serves up fresh solutions to the pancake problem
David Cutler is in the spotlight for his work on a tasty-sounding mathematics problem. In January, the New York Times featured a research paper authored by Cutler and Neil Sloane, the founder of The On-line Encyclopedia of Integer Sequences. Titled "Cutting a Pancake with an Exotic Knife," the paper explores the "lazy caterer problem," or how to cut a pancake or other circular object into the most pieces with the fewest cuts.
