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
Open-air quantum link bridges 13 miles, bypasses fiber wavelength lock
Free-space quantum network milestone: Brookhaven National Laboratory and Stony Brook University transmitted entangled photons ...
New free-space optical link adds a wireless component to the nation's longest quantum network
There's a new lighthouse on Long Island. But instead of shining light to guide ships through waterways, this one transmits and receives particles of light that carry quantum information. Perched atop a seven-story building at the U.S. Department of E...
A ghostly ribbon of stars reveals hidden dark matter
A faint ribbon of stars around a distant galaxy has become the first globular cluster stellar stream ever identified beyond the Milky Way. Because the stars trace the galaxy’s gravity, researchers used the stream to estimate how much invisible dark m...
A tiny “rainbow on a chip” could help supercharge 6G networks
Researchers have created a tiny chip that produces a stable “rainbow” of light capable of generating multiple high-frequency signals at once, potentially boosting the speed and capacity of future 6G networks. Its extreme precision could also make it...
Screen time at ages 1 and 6 may matter more than parents realize
More screen time during infancy and around the start of school was linked to poorer academic performance and weaker working memory years later. The findings suggest that early childhood may contain particularly sensitive windows when screen habits ca...
Scientists just imaged the hidden quantum shape of a molecule
Researchers have found a way to create a complete 3D image of a molecule’s wavefunction, one of quantum mechanics’ most fundamental yet elusive features. By combining advanced photoelectron measurements with newly designed algorithms, the University...
Language skills stay strong in older adults, even while other cognitive abilities decline
As people age, many cognitive functions tend to decline. Brain scanning studies have revealed corresponding changes in the function of a brain network that is involved in many of these cognitive functions, including working memory and problem-solving...
NASA is about to launch a powerful new eye on the universe
NASA’s Roman Space Telescope has been cleared for final launch preparations ahead of a targeted August 30 liftoff aboard SpaceX’s Falcon Heavy. The powerful new observatory will probe cosmic expansion, the history of the universe, and distant exoplan...
Trump to award Congressional Space Medal of Honor to Artemis II astronauts
The Artemis II crew will receive the Congressional Space Medal of Honor after becoming the first humans in more than 50 years to travel beyond the Moon. Their 10-day Orion mission also carried them farther into space than anyone in history.

Every quantum computer is built around qubits -- their fundamental units of data calculation -- which are incredibly ...
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 ...
Physicists built an 18-qubit silicon quantum chip that runs on its own inside a deep freeze
A team of physicists has demonstrated an 18-qubit quantum processor built on silicon that manages its own operation from ...
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...
