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
Trapping of single atoms in metasurface optical tweezer arrays
<p>Nature, Published online: 14 January 2026; <a href="https://www.nature.com/articles/s41586-025-09961-5">doi:10.1038/s41586-025-09961-5</a></p>Single strontium atoms are trapped in optical tweezer arrays generated via holographic metasurfaces, overcoming a critical barrier to realizing scalable neutral-atom quantum technologies.
Memories of items and their contexts are encoded by separate groups of human brain cells
<p>Nature, Published online: 14 January 2026; <a href="https://www.nature.com/articles/d41586-026-00016-x">doi:10.1038/d41586-026-00016-x</a></p>Human memory often needs to link specific items to the situation in which they feature. Brain recordings reveal that two distinct groups of neurons respond to stimuli and contextual information. These groups then cooperate to form flexible memories, rather than individual neurons encoding both signal types.
Quantum simulator reveals how vibrations steer energy flow in molecules
Researchers led by Rice University's Guido Pagano used a specialized quantum device to simulate a vibrating molecule and track how energy moves within it. The work, published Dec. 5 in Nature Communications, could improve understanding of basic mechanisms behind phenomena such as photosynthesis and solar energy conversion.
New state of matter discovered in a quantum material
At TU Wien, researchers have discovered a state in a quantum material that had previously been considered impossible. The definition of topological states should be generalized.
Chemists determine the structure of the fuzzy coat that surrounds Tau proteins
One of the hallmarks of Alzheimer’s disease is the clumping of proteins called Tau, which form tangled fibrils in the brain. The more severe the clumping, the more advanced the disease is.The Tau protein, which has also been linked to many other neurodegenerative diseases, is unstructured in its normal state, but in the pathological state it consists of a well-ordered rigid core surrounded by floppy segments. These disordered segments form a “fuzzy coat” that helps determine how Tau interacts wi

Show HN: Kalshi Market Intelligence and AI Signal Analyst
Hi HN,I built a lightweight market intelligence layer for Kalshi prediction markets.Instead of scraping pages, it intercepts Kalshi’s APIs to track:
• Stateful volume trends (rising / falling)
• Liquidity depth
• Basic sentiment signalsIt also includes a BYOK AI adapter so users can generate short trader briefs using their own LLM key (ChatGPT, Claude, Gemini, etc.). Designed to run on very low resources (fits Apify’s 1GB free tier).I built this as part of the Apify $1M Challenge and wou
Show HN: 26x speedup on BitNet sparse ops with AVX-512 and 2-bit encoding
I've been optimizing ternary operations for BitNet 1.58b and found significant overhead in the current implementation.I wrote a dependency-free C kernel (sparse-ternary-fma) using 2-bit encoding and AVX-512 instructions.Benchmarks on Intel Xeon (N=4096):Throughput (Dense): 2.38x faster (8.21 GFLOPS vs 3.45 AVX2)Throughput (Sparse 80% zeros): 26.12x faster (23.25 GFLOPS vs 0.89 Scalar)Memory: 4x denser (2-bit vs 8-bit standard)This approach packs 4 trits per byte and leverages sparsity-aware
I built an ingestion engine because I hate mundane tasks
There is nothing quite as soul-crushing as manually copy-pasting data from a PDF invoice into a database field.It's a waste of human intelligence.I tried existing tools, but they broke whenever a document layout changed.
I needed something robust enough to handle variable inputs without constant babysitting.I built Scanny AI using vision models to understand document structure rather than just relying on brittle regex or raw OCR.It identifies fields spatially and syncs structured JSON to t
Show HN: Touch grass – I built social media that wants you to close it
I wanted old school social media back. Actual connections with friends. Not pity likes and performances and highlight reels.All my friends have stopped posting. Everyone's a lurker now. I'm a lurker. The only time I see what anyone's doing is when it's a humblebrag. I have no idea what's actually going on in my friends' lives besides the ones I see every week or so.So I built touch grass. You post once a week: 3 easy questions, max 3 photos. Sunday 6pm mountain time
