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
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
Time-varying magnetic fields can engineer exotic quantum matter
Quantum technology has promising potential to revolutionize how large and complex amounts of information are processed. While already in use primarily in laboratory and research settings globally, quantum technologies are in a transition phase for broader industry applications across many economic sectors.
Scientists turn plastic waste into clean hydrogen fuel using sunlight
Scientists are using sunlight to turn plastic waste into clean fuels like hydrogen, offering a breakthrough solution to both pollution and energy challenges. While still in development, the approach could transform trash into a valuable resource for a low-carbon future.
MIT scientists finally reveal the hidden structure of a mysterious high-tech material
For decades, relaxor ferroelectrics have powered everything from medical ultrasounds to sonar systems, yet their inner atomic structure remained a mystery—until now. Researchers have finally mapped their three-dimensional structure in unprecedented detail, uncovering hidden patterns in how electric charges are arranged at the nanoscale. The breakthrough not only challenges long-standing assumptions about how these materials behave but also allows scientists to refine the models used to design th
NASA just took a huge step toward the Moon after Artemis II success
Artemis II proved NASA’s deep space systems are ready for the next leap. Orion survived its high-speed return with improved heat shield performance and pinpoint landing accuracy, while the SLS rocket nailed its trajectory. Even the launch pad upgrades paid off, with minimal damage despite the powerful liftoff. With only minor issues to resolve, NASA is now gearing up for Artemis III and future Moon missions.
NASA shuts down 49-year-old Voyager 1 instrument to keep it alive
Voyager 1 just powered down a nearly 50-year-old instrument to stay alive in deep space. The spacecraft is running critically low on energy, forcing NASA to make careful sacrifices to keep its mission going. Despite the shutdown, it continues to send back unique data from beyond our solar system. Engineers are now working on a bold plan that could extend its life — and possibly revive the instrument later.

Show HN: I built a RISC-V emulator that runs DOOM
Demo: https://www.youtube.com/watch?v=f5uygzEmdLwHi HN,I built a RISC-V emulator that implements the RV32IM instruction set and a minimal syscall interface to run DOOM. A few weeks ago, I got my first output with a simple hello world assembly program.Since then I have been working tirelessly to get DOOM to run.I needed to figure out how to run C programs first, and came across newlib, which allows the underlying environment to implement the syscall stubs one by one until the progr
Show HN: Valkyr LM Inference with Realtime Guarantees
Valkyr is a fresh take on LM Inference runtimes.It's quite different from llama.cpp, vLLM, or ZINC for example.Written in Zig, and super clean, with no dependencies apart from Vulkan Compute itself of course.While it supports multiple model families and features like an OpenAI compatibility server, a big thing is you can run it with strict time budgets running inside an existing Vulkan host.. think video games, AR/VR apps, edge devices, or robots.In addition it supports a rich probe in
Year old Nepali and unemployed, any advice for me?
I am in a spectacular situation.I graduated from CSE degree a bit late. I was 24 by the time I graduated. Then I worked in private firm for 2+ years.Then I quitted my job to prepare for Government IT jobs because they were stable, gave a Officer Level role for someone who is a BTech graduate.It has been 9 months since I started studying.Although I have little bit of savings, I was living with my parents.The household situation got really toxic with my father and I moved to my uncle's house(
