Anthropic says Claude discovered a CRISPR-like enzyme system. Its own post says the function is not yet known, ten reruns missed the array, and a researcher says it matches his unpublished work.

Anthropic said Claude discovered a novel enzyme system with properties reminiscent of CRISPR, with only high-level direction from its scientists. Its CEO called it a Claude-led discovery of a molecular machine that could represent a new gene editing mechanism.

The reality check

Anthropic's post says work to understand the function is ongoing, and The Next Web reports the preprint has not shown the enzyme is active. The Next Web also reports that ten reruns of the search all missed the array. A University of Copenhagen researcher told CNN his unpublished research describes the same finding.

Why care? A pattern in DNA is a lead, not a tool. Until the enzyme is shown to do something, a new gene editing mechanism is a suspicion.

Take this with youAnthropic says Claude found a CRISPR-like enzyme system. What it does is still unshown, and a Copenhagen researcher says his unpublished work describes the same finding.

Bezos says AI will let some people work three days a week. The coverage gives no timeline, and Amazon has cut about 30,000 corporate roles since late last year.

In a Fox News interview aired 7 October, Bezos said AI-driven productivity means some people will decide they can support their family working three days a week, and that it will be difficult to hire people.

The reality check

The American Bazaar reports he gave no timeline and did not explain how productivity gains would become shorter hours or higher incomes. Fortune reports Amazon has cut about 30,000 corporate roles since late last year. Amazon's CEO wrote in 2025 that the company expects AI to reduce its corporate workforce.

Why care? A forecast for the economy is not a schedule or a policy. Whether productivity reaches workers as shorter hours is the part the record leaves unshown.

METR's chart says AI task length doubles every seven months. A new preprint finds the same tenfold jump is not the same difficulty everywhere, and METR's own note warns the error bars are wide.

AI illustration for: AI task length is doubling every seven months, METR's chart says. A new preprint finds the same tenfold jump is much easier from 3 to 30 minutes than from 30 minutes to 5 hours, and a METR author warns the error bars run about a factor of two.

METR's 2025 post said the length of tasks AI agents can complete has been exponentially increasing, with a doubling time of around 7 months.
