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
Nuclear shell structure governs short-range nucleon pairing
<p>Nature, Published online: 03 June 2026; <a href="https://www.nature.com/articles/s41586-026-10616-2">doi:10.1038/s41586-026-10616-2</a></p>The scattering of high-energy electrons from three different nuclei demonstrated that short-range-correlated pairing depends far more on the specific quantum orbitals occupied by nucleons than predicted by theoretical models.

Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. The researchers describe in Science Advances how individual incentives to buy firearms can lead to a phenomenon they call "overarming." In an overarmed society, the collective cost of firearm ownership outweighs the individual benefits of possessing a gun.
Three Countries Own the Lithium Market. An MIT Startup Wants to Break Their Grip.
A new process for mining lithium-rich rock could slash costs and pollution—and decentralize global lithium production. Lithium mining is like a modern gold rush. The element is the main ingredient in batteries powering smartphones, electric cars, and even AI. Global demand is surging. Increased production could guide the world toward a more sustainable energy future.But ironically, current extraction methods offset some of those gains. Lithium mining involves separating the element from brines u
Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate according to the unique and complicated rules of quantum physics.
Venus will disappear behind the Moon in a rare June sky event
June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset. Mercury joins the pair to form a rare three-planet lineup, while the Moon puts on a special show by passing in front of Venus for viewers in parts of the Americas. The month also marks the start of astronomical summer and the return of spectacular deep-sky targets like the Ring Nebula and Veil Nebula.
Scientists simulated a nuclear fireball and found a surprise in the fallout
Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better understand how radioactive fallout forms. Their experiments revealed that the way vaporized materials cool can dramatically change the particles that eventually form, especially for volatile elements like cesium.
New discovery upends an 80-year-old theory of turbulence
Researchers discovered a way to reverse the direction of energy flow in turbulence, challenging a theory that has stood for more than 80 years. The finding could open new possibilities for controlling ocean currents, improving medical technologies, and enhancing climate forecasting.
Launch HN: Rudus (YC P26) – AI for concrete contractors
Hi HN, we’re Rishi and Sahil. We’ve developed Rudus (https://www.rudus.ai/), an AI-powered takeoff and estimation platform built for concrete subcontractors.Takeoff is the process of measuring and quantifying materials from concrete plan sheets. Rudus identifies every concrete structure (footings, walls, columns, slabs), pulls in related details, and eliminates hours of manual quantity calculation. Here’s a demo: https://www.youtube.com/watch?v=PAMNDRWEdlI.The probl

Dozens of mathematicians signed a declaration Tuesday calling for the discipline to resist beating the drum for artificial intelligence developers.
How a Richard Feynman formula could explain your dining habits in a new city
One of the dilemmas facing anyone in a new and unfamiliar city is where to dine out. You might consult guides, speak to locals, check reviews, and ultimately, try your luck. But if you're there for a while, at some point you're going to be asking yourself whether to visit new eateries or stick to the ones you've already tried and liked.
Cutting a photon in two creates an infinite swarm of particles
By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway for a single photon. The answer is deeply strange: attempting to cut a photon in two wouldn't produce two smaller photons, but instead conjure an infinite number of them out of thin air.
A stellar “Rosetta stone” reveals the source of mysterious cosmic signals
Astronomers have finally cracked the mystery behind a strange class of repeating cosmic signals that has baffled scientists for years. Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours.
Show HN: Glq LLM quantization using E8 lattice
I have with the help of AI create an open source method of E8 LLM code book quantization library called glq. I was interested in creating Glq
as a PC gamer and devops, interested in both LLMs and AI. The current high RAM prices and LLM resource usage also inspired me to write glq. A question arises could you try and squeeze more out a gaming GPU with limited VRAM size by using alternative LLM compression methods?Glq is effective compared to other LLM quantization algorithms at between 2-bits per
Show HN: Opthash – Rust implementations of Elastic and Funnel hashing
I first came across the paper “Optimal Bounds for Open Addressing Without Reordering” through a Quanta Magazine YouTube video a few months back. I went looking for an official implementation and couldn’t find one, so I decided to try implementing the paper's Elastic Hashing and Funnel Hashing in Rust.To that end, I build opthash, a Rust library providing ElasticHashMap and FunnelHashMap implementations (and more recently HashSet variants). They are at API parity with std::collections::HashM
