Claude found an unremarked DNA repeat array beside a known enzyme — Hacker News, September 23
The front page for Wednesday, September twenty third, two thousand twenty six. At the top, with about seven hundred and seventy points, Anthropic reports that Claude spotted a pattern sitting in public DNA data.
A wet lab and one prompt
Claude discovers a novel enzyme system with CRISPR-like repeats
Anthropic has stood up a life sciences group with a molecular biology bench. They pointed Claude at a database of DNA sequences and asked for interesting reverse transcriptases. The scientists supplied the prompt and the bench work.
What the search cost
Two hundred thousand enzymes, twenty reports
The agents pulled more than two hundred thousand of those enzymes, cut them to three and a half thousand candidate systems, and wrote up the best twenty for a scientist to check. Roughly nine hundred and fifty agents, twenty one hours.
An array of repeats
The thing it stopped on
The agent saw a tandem repeat array, laid out like a CRISPR array, beside an odd looking enzyme. Anthropic calls the three part system ART. The repeats get transcribed into a set of short RNA strands. Its function is still open.
The sober framing
In the thread
“Claude identified a previously undescribed genomic arrangement around a known reverse transcriptase.”
Commenter Spacecosmonaut offers a plainer wording, and the post backs it. The enzyme itself was already in the literature. The arrangement around it is the new part.
A pawl and a counter
Fixing the Portobello Police Station Clock
A community group bought an old police station and could not set the tower clock. The fix was a pawl on one gear. Lift it and the shaft turns. The chime box keeps no time, just an hour counter nudged by a switch.
Reading the status light
In the thread
“Long-long-short-short-short is 7 in morse code.”
The box blinks a status code the pair ran out of afternoon to decode. Commenter SaberTail reads it as Morse. Dash dash dot dot dot really is seven, though whether the box means the hour stays a guess.
Classification from the logits
Jev in 25 Lines of Python
A spam classifier in twenty five lines, a parody of the hype around Jev. Load a small model locally, put the choices in the prompt as letters, then read the model's scores for only those letters. Phishing, at about nine in ten.
Where the trick leaks
In the thread
“Your ‘choice’ tokens and thus their probabilities might get diluted in whatever else it wanted to say.”
Commenter sigmoid10 names the catch, and the post is doing exactly the thing described. A chat model wants to answer in prose, so the letter you measure competes with the sentence it meant to write.
What lands on the remote box
VSCode’s SSH Agent Is Bananas
Emacs has done remote editing for decades, living off the land on the connection. VSCode instead stages in an agent and its own copy of Node, which opens a socket back to your editor and can roam the filesystem, spawn shells, and persist.
Or: that is the feature
In the thread
“VSCode can't assume that your remote machine can access the wider internet.”
Commenter 10000truths pushes back. A tool built to edit files and run commands on a remote machine doing precisely that is the feature, and the tunnel may be the only route the agent has.
Voices you describe in words
Gemini 3.8 text-to-speech
Two new text to speech models. You describe the voice you want in plain words. Then you direct it line by line, including the sighs. Copying a real voice takes a thirty second sample and a recorded consent clip from its owner.
A change of nerve
In the thread
“I guess voice cloning is widely enough available now from other providers that Google are no longer hesitant to ship it.”
Commenter simonw puts the release down to a change of nerve rather than a change of capability. Cloning a voice is ordinary enough elsewhere that shipping it costs Google little.
