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
Strange Quantum Oscillations Reveal New Physics in an Exotic Material
Experiments and theoretical analysis show that under extreme magnetic fields, electrons in zirconium pentatelluride behave in ...
Why can AI generate Super Mario but not a wedge ramp for my robot vacuum?
I've been puzzled by something: AI generation can produce an elaborate
figurine, a cartoon character, even a convincing Super Mario — yet it
can't reliably make a simple wedge ramp so my robot vacuum can climb a
step. For context: I...
Show HN: Ditdah – A Morse App for the Terminal
I passed the Morse exam when I got my novice license, but I haven't started
using Morse until recently. I'm really a beginner: I can key at about 15 WPM and
am practicing for 20, but I'm still making mistakes, with an extra dit or dah...
Show HN: Budgethole.com – Close the US federal deficit yourself
Hi HN,I could never quite grasp the large numbers floating around in the articles and discussions about the federal deficit. So I built BudgetHole.com as a personal side project, a web app that lets you play with 150+ policy options and see how they...
Physicists create a tiny “Big Bang” with surprisingly small atomic nuclei
Researchers at CERN have created microscopic versions of the early Universe by colliding surprisingly small atomic nuclei at nearly the speed of light. The collisions produced quark-gluon plasma, the ultra-hot matter believed to have filled the cosmo...
Quantum computer microscope is set to significantly improve electron microscopy
Electron microscopes are used wherever particularly small details need to be imaged. But from a strictly physical point of view, every electron in a conventional electron microscope represents a missed opportunity: If all you do is count electrons, a...
A hidden “on switch” in human DNA has finally been decoded
Researchers have used AI to uncover the DNA signature of a key genetic “switch” involved in turning genes on. After analyzing about 500,000 DNA sequences, the model identified the initiator in roughly 60% of human genes. The breakthrough could help p...
Scientists turn tiny “defects” into a 5.5x heat transfer boost
Scientists have developed an ultrathin coating that could dramatically improve how efficiently heat is transferred during condensation. By turning tiny polymer structures once considered “defects” into places where water droplets can form, then helpi...
Black holes keep tearing these stars apart, but they survive
Astronomers have found stars that repeatedly skim past supermassive black holes, surviving each encounter while producing a new burst of light. In some systems, those flares mysteriously fade with every return. Researchers now think the key may be st...
Show HN: Forst – migrate TypeScript back ends to Go incrementally
Over the past ~1.5 years I've been working on this programming language called Forst with the primary goal of replacing TypeScript on the backend.I'd seen many times that running JavaScript on the backend often leads to memory spikes, espec...
IBM quantum computer reaches 15-minute computing milestone
IBM and University of Chicago researchers have demonstrated a quantum computation that took about 15 minutes, while leading ...
Realistic solid-state model brings fractons in quantum spin liquids closer to detection
Quasiparticles arise from the complex interaction of many particles in solids; for example, we describe lattice vibrations in ...
Quantum Computing Is Already Here for Some Federal Agencies. What Comes Next?
Federal agencies are now using quantum computing for logistics and security. Learn how infrastructure readiness enables ...
Physicists Think They’ve Discovered a New Type of Quantum Matter
Quantum mechanics is all about explaining the weirdest, most unlikely aspects of our reality, including oddities we might not ...
WiMi's Next-Generation Quantum Convolutional Neural Network Reshapes Classical Data Classification Methods
From the perspective of technical implementation logic, this quantum convolutional network adopts an overall hybrid quantum-classical architecture design. First, classical data is mapped to the ...
An Oxford Physicist Discovered Particles Doing the Impossible. It Could Finally Solve the Quantum Gravity Mystery.
This idea may help address the black hole information paradox, especially the problem that black holes seem to violate a key ...
This frozen fiber makes light and sound interact 1,000x more strongly
Freezing the liquid core of an optical fiber produced an extreme environment where light and sound interact more than 1,000 times more strongly than in ordinary fibers. Researchers used the effect to create optoacoustic memory, potentially paving the...
JWST finds early galaxies may be 4 times more massive than thought
Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes...
Ask HN: How to Claude Like Anthropic
I just received an email from Anthropic. Besides the usual new feature ad, there is a piece that I find quite amusing:> How to Claude like Anthropic> "My daily driver currently looks like: two lead agents that keep each other accountable a...
