The theory of evolution lays the foundation of our understanding of why and how cancers change over time and adapt to therapy.
But cancer evolution is a bit special: it is incredibly fast, with multiple routes to adaptation explored at the same time under therapy, and goes beyond genetic alterations, leveraging on heritable (and therefore Darwinian) epigenetic alterations to accelerate evolution.
Important note: whereas genetic alterations are difficult to revert, chromatin changes are, in principle, “editable”. Hence maybe epigenetic drivers of cancer evolution can be "reverted"?
Here’s our take, after more than 10 years working in this field, on the genomic and epigenomic evolution of colorectal cancer. Link below 👇

Election Tuesday is just two days away. For those eligible to vote in the U.S., please make time to go to the polls to vote (or mail in your ballot if you haven't already). Voting is a great privilege of living in a democracy and how we all make our collective voices heard. 🗳️

How does the mitotic spindle adapt to genomes that differ in size by more than 10,000-fold? Our new paper in @NatureCellBio reveals a simple scaling law and the physics behind it: chromosome crowding! 🧵

I captured this video in my lab to show the power of medicines called T-cell engagers.
Left: T cells move in and out of a cancer tumoroid, largely ignoring it.
Right: Add a T-cell engager, and the T cells attack. Once they recognize their targets, they tear through the tumor.

New analysis reveals that development is not a mere readout of a genetic program, but rather a dynamic process in which communities of cells build themselves, and the very landscape they navigate, by mutual negotiation and interaction, into an organism.

I had fun chatting with Exa for their inclusion on the 3b1b talent page. It got me thinking about how a lot of the goals for better search end up aligning with goals of better credit assignment/attribution.
We sat down with @3blue1brown to discuss our research vision of "Attention over all the world's information."
Plus why knowledge should not live in model weights, the compression trick behind cheaper retrieval, and why we hire through work trials.
1:20 – What is “attention over everything”?
4:46 – A knowledge graph of the whole web
11:32 – How do you evaluate search for AI agents?
15:13 – Why not put everything in the weights?
22:55 – Why Exa hires through work trials
25:15 – The compression trick behind cheaper retrieval
27:40 – Dealing with misinformation

Applications are now open for two new Anthropic Fellowships.
STEM Fellows (science and engineering) and Conceptual Reasoning Fellows (philosophy, cognitive science, economics, policy, and law) will spend four months at Anthropic from January 2027, working to help Claude reason well about some of the hardest problems in those fields.
For more information, see the descriptions below. The application deadline is October 28.

1/5 Telomerase has long been linked to chromosome maintenance in eukaryotes. Now, we show that telomerase-like activity is also present in bacteria, shedding new light on its ancient origins.
Excited to share that our work on DRT10 is now out in @Nature!

Most important, we want to get this model into as many scientists’ hands as we can.
Today, we’re announcing that 10,000 scientists will get the highest usage tier access to Gemini 4 Argon in Google @antigravity free of charge for 6 months.

Atrophy is a choice. Machines play chess better than we do, but we still play and reap many benefits from it. Let AI perform tasks, but never stop challenging your mind, or yourself.

There are people who leave a mark on the world, and then there are people who change it entirely. Steve changed the world and so many lives in the process. He certainly changed my life forever. His spirit lives on in everything he created and everyone he inspired.
