NIST was 5 μs off UTC after last week's power cut
If you were 5 microseconds late today, blame it on NIST. Their facility in Boulder Colorado just had its power cut for multiple days. After a backup generator failed, their main ensemble clock lost track of UTC, or Universal Time Coordinated. But even if you used the NTP timing servers they run, they were never off by…

More on whether useful quantum computing is “imminent”
These days, the most common question I get goes something like this: A decade ago, you told people that scalable quantum computing wasn’t imminent. Now, though, you claim it plausibly is immi…

Economics of Orbital vs. Terrestrial Data Centers
Before we get nerd sniped by the shiny engineering details, ask the only question that matters. Why compute in orbit? Why should a watt or a flop 250 miles up be more valuable than one on the surface? What advantage justifies moving something as mundane as matrix multiplication into LEO?

If a Meta AI model can read a brain-wide signal, why wouldn't the brain?
In 2023, Meta researchers were able to decode images in thoughts from the brain's magnetic fields. What if that's how the brain coordinates it's own global state?

CRISPR fungus: Protein-packed, sustainable, and tastes like meat
Researchers have successfully used CRISPR gene editing technology to create a fungi strain that is highly efficient, more nutritious, and significantly more sustainable than its natural counterpart. The fungus Fusarium venenatum already stands out for its meat-like flavor and texture, leading to its approval for food…

$5 whale listening hydrophone making workshop
Whale songs were first noticed by accident, when analysts tracking Russian submarines at the height of the cold war heard cetacean interference instead. An engineer sent some recordings to Roger Payne, a biologist friend of his, who did something that proved pivotal: he played the hours-long recordings on his hi-fi at…

Beautiful Abelian Sandpiles
I can't remember where I first saw them, but ever since, I have been unable to forget them: abelian sandpiles. I'm far from the only one . They're remarkably simple, yet produce lovely symmetric patterns. I loved them so much that I adorned the title banner of this blog with an animation of an abelian sandpile. But…

Coffee linked to slower biological ageing among those with severe mental illness
New research from King’s College London finds that coffee consumption within the NHS recommended limit is linked to longer telomere lengths – a marker of biological ageing – among people with bipolar disorder and schizophrenia. The effect is comparable to roughly five years younger biological age.
