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

Show HN: Quadium 4004 – A visual laboratory for the Intel MCS-4 architecture
I’ve spent a few months building this. It’s basically a visual env for the Intel 4004 because I wanted to see what's actually happening in the buses and registers without 'black boxes'.<p>It has a transpiler called QuadBasic to go from high-level syntaxs to native MCS-4 machine code. Just a personal project from a senior dev to tribute the 1971 pioneers. Happy to answer any tech questions if you find it interesting.
Show HN: Cubitoo Journal, your web journaling app
It was first an iOS app but now it's 100% proud Ruby on Rails web app that works everywhere you can receive your emails. With 18+ guided journaling programs and things that make journaling easy, fun, and interesting.<p>It's an alpha/beta release so please don't hesitate to ask questions and share your feedback — I want to make it the best journaling app :-)
Astronomers pin down the origins of a planetary odd couple
Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally “lonely” hot Jupiter is sharing space with a mini-Neptune, in a rare and unlikely pairing that’s had astronomers puzzled since the system’s discovery in 2020.Now MIT scientists have caught a glimpse into the atmosphere of the mini-Neptune, which is circling inside the orbit of its Jupiter-sized companion, and discovered clues to explain the origins of this unusual planetary system.I
An AI Just Beat Doctors at Diagnosing ER Patients
AI has aced medical exams, but there’s a wide gap between tests and the real world. A new study suggests the divide is closing. Emergency doctors make high-stakes decisions in fast-paced, often chaotic situations. They have to figure out which patient most urgently needs care, what’s wrong, and what to do next.AI could lend a hand. In a series of challenging scenarios, OpenAI’s o1-preview model matched or exceeded doctors in clinical reasoning. Debuted in 2024, the AI is a large language m
Scientists just created exotic new forms of matter that shouldn’t exist
A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions. By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challenges in quantum computing. This breakthrough suggests that the future of quantum technology may depend not just on what materials are made of, but how t

SQL access to crypto market data, not just JSON
Hi HN,I’m Nazim, founders of Koinju.io and I wanted to share here an exploratory option we opened very recently: providing access to our database, which contains all cryptocurrency market data, via SQL. REST give access for direct retrieval but we're thinking more and more that SQL access for analytical work over a unified crypto market data layer could be of something because of llms.This was partly triggered by Didier Lopes, ceo of OpenBB recent essay on financial firms owning the infrast
Can anyone point me to a ShowHN first post policy documentation?
edit: project link is https://github.com/upwindchange/Autai<p>I had an open source project launching but I found out that I cannot make ShowHN post, the explanation given to me is very vague, I am not sure what should I do to get myself qualified? Is there some quantized instruction like "how many days the account should be registered" or "how many posts/comments/upvotes" the account should get qualified? Thank you for your guidance.
Rett syndrome study highlights potential for personalized treatments
Although many studies approach the developmental disorder Rett syndrome as a single condition arising from general loss of function in the gene MECP2, a new study by neuroscientists in The Picower Institute for Learning and Memory at MIT shows that two different mutations of the gene caused many distinct abnormalities in lab cultures. Moreover, correcting key differences made by each mutation required different treatments.“Individual mutations matter,” says Mriganka Sur, senior author of the new
Symmetry says these crystal vibrations can never mix, but an exotic quantum phase rewrites the rules
Symmetry is one of the most fundamental principles in nature. It describes the rules that make an object look unchanged after a rotation, reflection, or other transformations. In materials, symmetry governs how atoms and electrons are arranged, and how they move together. Crucially, symmetry can even prevent certain collective atomic motions (vibrations) from interacting at all: some are simply forbidden to talk to each other. But what if those symmetry restrictions are not as rigid as they seem
Magnon lifetime extended 100x paves the way for mini quantum computers
Magnons are tiny waves in magnetization that travel through solid magnetic materials, much like the ripples that spread across a pond when a stone is thrown into it. Unlike photons, which travel through empty space or optical fibers, magnons propagate within a magnetic solid. Their wavelengths can be reduced to the nanometer range, meaning that magnonic circuits could, in principle, fit onto a chip no larger than those found in today's smartphones. Furthermore, as an excitation of a solid, a mag
