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

Material previously thought to be quantum is actually a new, non-quantum state of matter

Magnetic materials in a quantum spin liquid phase are of great interest in the pursuit of exotic state of matter and quantum computation. But in the quantum realm, things are not always what they seem. A study, published in Science Advances and co-led by Rice University's Pengcheng Dai, found that the material cerium magnesium hexalluminate (CeMgAl11O19) was not actually in a quantum spin liquid phase despite evidence suggesting it was.

A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and develop quantum technologies, as they can give rise to exotic and rare phases of matter.

Astronomers discover giant cosmic sheet around the Milky Way

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a gigantic, flat sheet of matter surrounded by huge empty voids. This hidden structure—dominated by dark matter—balances gravitational forces and lets neighboring galaxies drift outward. The discovery finally explains the puzzling motions of galaxies just beyond our Local Group.

Electrons catapult across solar materials in just 18 femtoseconds

Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a “molecular catapult.” In experiments lasting just 18 femtoseconds, researchers at the University of Cambridge observed electrons blasting across a boundary in a single burst, far faster than long-standing theories predicted. Instead of slow, random movement, the electron rides the natural vibrations of the molecule itself, challenging decades of design rul

Moar Updatez

To start on a somber note: those of us at UT Austin are in mourning this week for Savitha Shan, an undergrad double major here in economics and information systems, who was murdered over the weekend by an Islamist terrorist who started randomly shooting people on Sixth Street, apparently angry about the war in Iran. Two other innocents were also killed.As it happens, these murders happened just a few hours after the end of my daughter’s bat mitzvah, and in walking distance from the venue.

Quantum stock surges: IonQ stock climbs after earnings beat

Show HN: Ouroboros – Post-quantum P2P messenger with zero servers

After watching too many "privacy" apps get subpoenaed or shut down, I wanted a communication tool that literally cannot be shut down because it has no servers to seize. Ouroboros is a Rust-based P2P stack with two modes: 1. Live sessions: Two peers connect directly using just a shared passphrase. The passphrase deterministically generates identical network parameters on both sides, so they can find each other without any coordination server. 2. EtherSync spaces: Async file sharing and
