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

Ask HN: What happens to world economics when humanity reaches triade?
Hey folks, I'm intrigued by the consequences of what do you think it will happen to the global economy when humanity reaches these buzzword state-of-the-art technologies, like AGI, Quantum Computing and Robotics?<p>I mean when those things becomes so accessible and cheap that it will be considered a commodity<p>What do you think will happen to our society?
Five-Year-Old Mini Brains Can Now Mimic a Kindergartener’s Neural Wiring. It’s Time to Talk Ethics.
Among pressing ethical concerns are whether brain organoids could one day feel pain or become conscious—and how would we know? When brain organoids were introduced roughly a decade ago, they were a scientific curiosity. The pea-sized blobs of brain tissue grown from stem cells mimicked parts of the human brain, giving researchers a 3D model to study, instead of the usual flat layer of neurons in a dish.Scientists immediately realized they were special. Mini brains developed nearly the whole rang
Astronomers discover one of the Universe’s largest spinning structures
Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that appears to be slowly rotating as a whole. This coordinated motion is far stronger than expected by chance and hints that galaxy spin may be inherited from the cosmic web itself. The finding opens a new window into how galaxies formed and how matter flows across the Universe.
A Christmas tree 80 light-years wide appears in space
This Christmas, astronomers are highlighting a spectacular region of space that looks remarkably like a glowing holiday tree. Known as NGC 2264, this distant star-forming region sits about 2,700 light-years away and is filled with newborn stars lighting up clouds of gas and dust. The stars form a triangular shape called the Christmas Tree cluster, crowned by the dramatic Cone Nebula and wrapped in the swirling Fox Fur Nebula below. Together, these features create a festive cosmic scene spanning

My Christmas gift: telling you about PurpleMind, which brings CS theory to the YouTube masses
Merry Christmas, everyone! Ho3!Here’s my beloved daughter baking chocolate chip cookies, which she’ll deliver tomorrow morning with our synagogue to firemen, EMTs, and others who need to work on Christmas Day. My role was limited to taste-testing.While (I hope you’re sitting down for this) the Aaronson-Moshkovitzes are more of a latke/dreidel family, I grew up surrounded by Christmas and am a lifelong enjoyer of the decorations, the songs and movies (well, some of them), the message
What are asteroids really made of? New analysis brings space mining closer to reality
Scientists are digging into the hidden makeup of carbon-rich asteroids to see whether they could one day fuel space exploration—or even be mined for valuable resources. By analyzing rare meteorites that naturally fall to Earth, researchers have uncovered clues about the chemistry, history, and potential usefulness of these ancient space rocks. While large-scale asteroid mining is still far off, the study highlights specific asteroid types that may be promising targets, especially for water extra
Show HN: A local-first, reversible PII scrubber for AI workflows
Hi HN,I’m one of the maintainers of Bridge Anonymization. We built this because the existing solutions for translating sensitive user content are insufficient for many of our privacy-concious clients (Governments, Banks, Healthcare, etc.).We couldn't send PII to third-party APIs, but standard redaction destroyed the translation quality. If you scrub "John" to "[PERSON]", the translation engine loses gender context (often defaulting to masculine), which breaks grammatical
Show HN: Does Information Density Cause Time Dilation?
Full Paper (Zenodo):https://zenodo.org/records/18027729Help Needed:I am looking for feedback on the experimental setup.The main engineering challenge is maintaining GHZ coherence long enough to isolate the effect from environmental noise.If you haveHi HN. Standard General Relativity posits that time dilation is caused solely by mass-energy. But what happens when information entropy reaches a critical density?I have released Version 2.0 of my paper, proposing the Information-I
Show HN: I built an open-source Linux-capable single-board computer with DDR3
I've made an ARM based single-board computer that runs Android and Linux, and has the same size as the Raspberry Pi 3!Why? I was bored during my 2-week high-school vacation and wanted to improve my skills, while adding a bit to the open-source community :PThese were the specs I ended up with:
- H3 SoC
- Quad-Core Cortex-A7 ARM CPU @ 1.3GHz
- Mali400 MP2 GPU @ 600MHz
- 512MiB of DDR3 RAM (Can be upgraded to 1GiB)
- WiFi, Bluetooth & Ethernet PHY
