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 create stable 'boron graphene' and uncover quantum liquid crystal state

Graphene has long been regarded as one of the most promising materials for future electronics, but its relatively weak electron interactions have limited its potential for applications such as high-temperature superconductivity. Now, researchers from Tohoku University have overcome a major obstacle by creating a stable version of the long-sought "boron graphene" on the surface of a three-dimensional crystal, revealing a new quantum state that could lead to more energy-efficient electronic device

Ask HN: Is consciousness fundamentally a process of preserving identity?

{(Contradiction ->) Expression -> Violence (a circular response to contradiction, violence diverts attention and causes forgetfulness) => Implicitly, there’s an image containing contradictions, which is explicit because one assumes themselves from an identity that still holds under such interpretation}{(Expression ->) Contradiction -> Forget (a dialectical response to contradiction, without the violence) => Either there’s a lack of knowledge, or there’s a failure to think; i.e.

Show HN: I built a zero-regex AI WAF (200MB VRAM). Please try to bypass it

Hey,Tired of maintaining massive regex rulesets to catch WAF bypasses, my team and I built hCAWN – a completely zero-signature, pure-math WAF.Instead of known signatures, it catches 0-days using a hybrid model running on <200MB VRAM (via dynamic batching):LLM Cognitive Shock: A highly quantized Gated Attention model that spikes on structural anomalies (e.g., Log4Shell, SSTI).Syntax Jitter: A mathematical calculation of chaos and transitions between alphanumeric characters and special symbols.

Show HN: Pullboard – a work queue for agents, built to run a quant desk

Hello HN.Pullboard (https://pullboard.dev/) is the shared place work lives. You talk to one agent about what you want, and the rest of the fleet can organize around the resulting work without manually dispatching every task or re-explaining the context and any other in-flight work. It helps keep agents coherent.I run a small quantitative trading operation with a fleet of coding agents, and I originally built Pullboard to manage high-velocity work across complex projects. With Pull

Schrödinger‑like charges in six‑molecule clusters point to new quantum components

Researchers from the University of Basel have published details of how electrons within a cluster of molecules interact with one another and can be controlled. Their findings pave the way for new approaches to developing quantum components and electronic circuits on the nanometer scale.

Statistical method broadens forecasts by modeling uncertainty beyond average outcomes

When it comes to statistics, we usually expect to be informed about what happens "on average." But sometimes the key information lies in deviations from that mean: how likely is heavy rain, and how likely is it to remain dry? So-called distributional regression describes not only the mean but also the distribution of possible values.

Scientists achieve all-electrical control of single-molecule quantum states

Quantum technologies promise revolutionary advances in computing, sensing and information processing. However, controlling individual quantum bits (qubits) at the atomic scale remains a major challenge because conventional approaches rely on magnetic fields, which are difficult to confine to a single molecule.

New 3D silicon chip stacks circuits on top of each other to boost computing power

The massive hardware demands of artificial intelligence (AI) applications are stretching the physical and structural limitations of semiconductors. But researchers have engineered a three-dimensional silicon chip that they propose as the solution.In a new study published May 27 in the journal Nature, scientists found a way to cram more computing power into a chip by stacking silicon circuits in multiple layers in a way that doesn't impact performance. Stacking chips v

A new 'library' for Feynman integrals

Theoretical physicists at Johannes Gutenberg University Mainz (JGU) have developed a new method of ordering Feynman integrals. This critical step in making theoretical predictions for high-energy precision measurements has posed a major computational bottleneck until now.

Braided, exotic particles could build reliable, universal quantum computers

A truly useful quantum computer must be able to run any algorithm, with the same versatility an ordinary laptop offers. Physicists have now shown a new way to give a quantum computer exactly that flexibility, harnessing the capabilities of exotic quantum particles called non-Abelian anyons.

Quantum teleportation could reduce photon loss in long-distance communications

Quantum technologies, which leverage the principles of quantum mechanics, have been found to outperform their classical counterparts on specific tasks. Among other things, past studies have highlighted the potential of quantum systems that can enable long-distance communication, using photons (i.e., particles of light) to carry quantum information.

Quantum breakthrough links light and magnetism in atomically thin materials

A new review highlights exciting progress in atomically thin quantum materials where light and magnetism work together in ways never before possible. In these materials, light-generated excitons can interact directly with magnetic behavior, creating opportunities to control magnetic states using light alone. Scientists believe this could pave the way for advanced optical memory, quantum devices, and ultra-efficient photonic technologies.

NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock. The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from its molten interior, with signs that volcanic outgassing may even create temporary clouds.
