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

The Quantum Computing ETF That Could Be Bigger Than AI, and 2 Tech Funds Riding the Same Wave
Quantum computing is no longer a physics experiment. Google’s Willow chip, IBM’s quantum roadmap expansion, and IonQ’s commercial contracts have pushed the technology from research labs toward real enterprise applications. Markets are pricing in the possibility that quantum could deliver an inflection point similar to generative AI in 2023. The question for investors is how ...

Best way to detect ASCII nudes on Steam profiles?
If anyone is familiar with Steam profiles, and specifically the profile pages of Valve's CS2 players, you will know that quite a few profiles have pornographic or nude ascii art in the comments.These pages are publicly viewable, but would be viewable if you were required to have a Steam account. I'm not judging them morally, although Valve could easily do something with the privacy settings or remove them.I've scraped lots of these Ascii porn comments, I've rendered them as P
Show HN: Whirligig
I wanted to share this again since I've made some significant updates since I last posted it!<p>The site now displays artist images and also has a map.<p>In general I'm really pleased with the mobile UX, which I think is quite clean.<p>Feedback appreciated and welcomed!
Show HN: A WYSIWYG word processor in Python
Hi all,Finding a good data structure for a word processor is a difficult problem. My notebook diaries on the problem go back 25 years when I was frustrated with using Word for my diploma thesis - it was slow and unstable at that time. I ended up getting pretty hooked on the problem.Right now I’m taking a professional break and decided to finally use the time to push these ideas further, and build MiniWord — a WYSIWYG word processor in Python.My goal is to have a native, non-HTML-based editor tha
Show HN: Bullseye2D – A Dart library for cross-platform 2D games
I posted this here about a year ago, but I just pushed a 2.0 release, so I hope you don't mind a second look :)Bullseye2D is a 2D game library for Dart with a very simple API. The new version now supports multi-platform. It compiles to the web via a WebGL2 renderer, or natively to Windows, macOS and Linux through an SDL3 backend (which itself supports Vulkan, DirectX, Metal, and OpenGL renderers).It doesn't depend on Flutter and has very few dependencies (except SDL3). It mostly provid
Show HN: A free study guide for the AWS DVA-C02, built from my own exam notes
Hello!<p>I've been taking some notes to prepare the AWS DVA-C02 exam and decided to feed them to Claude to make them more readable. I was quite impressed by the result so I though I might share it for free.<p>I had fun building this little website and I'd love to get some feedback and improve the content.
Life on Mars? Tiny cells just survived shock waves and toxic soil
Mars may be hostile, but it might not be entirely unlivable. In lab experiments, yeast cells survived simulated Martian shock waves and toxic perchlorate salts—two major environmental threats on the Red Planet. Their secret weapon was forming protective molecular clusters that shield critical cellular functions under stress. Without these defenses, survival plummeted, pointing to a potential universal strategy life could use beyond Earth.
The Universe is expanding too fast and scientists still can’t explain it
A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s faster than early-Universe models predict. By linking multiple distance-measuring techniques, scientists ruled out simple errors as the cause of the discrepancy. The persistent “Hubble tension” now looks more real than ever. It could mean our current model of the cosmos is incomplete.

How to Build Better Digital Twins of the Human Brain
Brain twins where regions are allowed to compete for resources behave more like the real thing. The potential to create personalized digital twins of your brain and body is a hot topic in neuroscience and medicine today. These computer models are designed to simulate how parts of your brain interact and how the brain may respond to stimulation, disease, or medication.The extraordinary complexity of the brain’s billions of neurons makes this a very difficult task, of course, even in the era
High-resolution imaging captures cavity-induced density waves in a quantum gas
A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as photon leakage or the peak in energy deposition of a fast charged particle (Bragg peaks), have been used to detect this kind of ordering. Prior to this study, there had been no direct, high-resolution in situ imaging of cavity-induced density-wave order in ultr
'Poor man's Majoranas' can be used as quantum spin probes
A Majorana fermion is a particle that would be identical to its antiparticle. Such an object has not yet been found. However, certain solid materials exhibit analogous behavior as if Majorana fermions were present through collective excitations of the system called quasiparticles.

Ask HN: Improving as mid-level dev with forced use of LLMs
I’m interested in how do you grow as a developer when the usage of LLMs is basically forced on you?Background: 8-ish years of computational physics & chemistry research (scipy) and switched over to industry backend dev (.Net) 2 years ago. Goal is to grow in backend dev.So far I’ve been resisting them as much as possible in favor of old school rtfm, docs, and ddg/so, so I’d actually learn, but the org is insisting on us doing as much as possible copilot stuff (with tracking usage metrics
