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
Japan develops its first neutral-atom quantum computer
Japanese researchers are making headway in the field of quantum computing, or systems that are much faster at solving complex ...
IBM connects first modular cryogenic systems in milestone toward fault-tolerant quantum computing
Cooled to below 15 millikelvin, more than 180 times colder than deep space, the build out marks a step forward in the ...
Quantum Computers Could Wipe Out 30% of Bitcoin. XRP Says Only 0.03% of Its Supply Is at Risk
Two viral numbers are shaping how investors think about quantum risk across Bitcoin and XRP, but both figures measure ...
I've tested some local LLMs on prosumer hardware, here are some findings
I have been benchmarking local LLMs on a Mac M4 Pro 24 GB RAM using LM Studio. I've tested mostly with 4-bit quantization, both MLX and GGUF, from 4b to 35b models, with speeds of 3 to 40 tokens/second.Results briefly:- fast small model -&g...
Ask HN: Finding Equity Only Jobs
(throwaway account)After a long career at big tech companies, I saved enough money to FIRE and I quit my job about a year ago. While I enjoy the peace of mind and the lack of stress, I enjoy building things and spending the rest of my life doing noth...
Ask HN: Is there a stronger moat in marketplaces in the age of SaaS AI Slop?
Basically, what I’m trying to say is: software is cheap to produce now, but not necessarily easy to customize.It seems like everyone is honing in on distribution and capital as the moat. We have all these vibe-coding platforms and a flood of applicat...
Scientists Observe Quantum Heat Waves at Room Temperature For The First Time
A visualization of the ordered phonon heat flow. (H-Lab/UCLA) We've got another notable first in the field of physics to ...
Why banishing irrational numbers could trigger a revolution in quantum theory
Irrational numbers have underpinned quantum mechanics for a century. Removing them could eliminate its strangest features and ...
99 years later, Einstein’s letter about quantum mechanics is still the most famous argument in physics
The letter says der Alte, the Old One, not God — and it went to the very friend who'd win the Nobel for the idea it attacked. The full Einstein biography behind the five polished words, from the ...
Unitree Claims New Humanoid Robot Outruns Usain Bolt
The flashy company, which recently completed a blockbuster IPO, appears to be leading the pack of humanoid robot makers. Increasingly, companies are building humanoid robots that perform impressive athletic feats to mark the field’s progress. Now, Ch...
Show HN: Maya Calendar
In a similar vein to the French Republican Calendar app I built a while back (https://frcal.qt.ax/, https://news.ycombinator.com/item?id=30658487), I built this implementation of the Maya calendar.For some more details r...
Show HN: I built a lite LPU that can do inference on Karpathy's MicroGPT
We had no guide or course that teaches chip design at our university. We had taken a digital logic course, but were disappointed with the fact that the most complex project we did was building a full adder in Quartus using logic blocks, not even in R...
Vacuum-fluctuation-enhanced superconductivity demonstrated for the first time
In a study published in Nature on Aug. 19, a research team has enhanced superconductivity through vacuum fluctuations for the first time. The achievement marks a significant advance in controlling quantum states of matter.
Open-air quantum link bridges 13 miles, bypasses fiber wavelength lock
Free-space quantum network milestone: Brookhaven National Laboratory and Stony Brook University transmitted entangled photons ...
Brain circuit keeps tabs on what just happened to aid judgment of what’s happening now
A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what’s going on around it. On one hand, it has to be open to whatever new sensory information may come its way, but on the other hand, just to...
New free-space optical link adds a wireless component to the nation's longest quantum network
There's a new lighthouse on Long Island. But instead of shining light to guide ships through waterways, this one transmits and receives particles of light that carry quantum information. Perched atop a seven-story building at the U.S. Department of E...
A ghostly ribbon of stars reveals hidden dark matter
A faint ribbon of stars around a distant galaxy has become the first globular cluster stellar stream ever identified beyond the Milky Way. Because the stars trace the galaxy’s gravity, researchers used the stream to estimate how much invisible dark m...
A tiny “rainbow on a chip” could help supercharge 6G networks
Researchers have created a tiny chip that produces a stable “rainbow” of light capable of generating multiple high-frequency signals at once, potentially boosting the speed and capacity of future 6G networks. Its extreme precision could also make it...
Screen time at ages 1 and 6 may matter more than parents realize
More screen time during infancy and around the start of school was linked to poorer academic performance and weaker working memory years later. The findings suggest that early childhood may contain particularly sensitive windows when screen habits ca...
