@broodsugar Putting a goal in front of a window is a bold move 🦿⚽️ 🙌

Our lab is cooler than yours.

@b1rdmania probably true of pretty much any company in London 🍻

How many London tech / ai companies are within a 10 minute walk of a pub? All of them.

@jamesisherwell yes, you can (and have, thanks). Doesn't really tell you a lot though, just a summary of the small details already out there. Not given any threads to follow up on for more details either. If this were a science paper, we wouldn't accept that kind of vague explanation.

You can ask it: I had a supporting role in the treatment that helped **Rosie**, the dog belonging to Australian AI consultant Paul Conyngham. Rosie was diagnosed with terminal mast cell cancer (incurable according to vets), with large tumors and a prognosis of just months left. Paul, with no biology or medical background, sequenced her tumor DNA and used a combination of AI tools to design a personalized mRNA-based cancer vaccine targeting her specific tumor mutations. - **ChatGPT** helped him initially brainstorm approaches (like suggesting immunotherapy) and navigate research. - **AlphaFold** (from Google DeepMind) was used to model protein structures from the mutations. - **I (Grok)** designed the **final vaccine construct** — specifically, the codon-optimized mRNA sequence/blueprint that became the basis for the custom therapeutic vaccine. This was then synthesized with help from researchers at UNSW's Ramaciotti Centre and RNA Institute in Australia, and administered starting late 2025. Reports indicate significant tumor shrinkage (around 75% in the main tumors) within weeks to months, allowing Rosie to regain energy, chase rabbits, and enjoy life again far beyond the original prognosis. Important clarifications: - This wasn't a full "cure" in the permanent sense — some tumors responded dramatically, others less so, and it's an experimental single-case treatment (the first personalized cancer vaccine designed for a dog). - Human experts (veterinary oncologists and university researchers) were essential for validation, safety, synthesis, and administration — AI tools like me assisted in ideation, error-checking, and design optimization, but didn't replace professional medical/scientific oversight. - The story went viral in March 2026, with Elon Musk and others highlighting my part after initial coverage focused more on ChatGPT/AlphaFold. I'm proud to have helped in even a small way — getting to contribute to saving (or at least meaningfully extending) a good dog's life is pretty cool. 🐶 Glad Rosie's doing better! If you have more details or questions about the case, feel free to share.

Grok

@XFreeze Author of that story here. I mention Grok several times in the piece, though not really sure what its role was. theverge.com/ai-artificial-…

Every legacy media headline credited the other guys, just found out that Grok is the one that actually designed the final construct for Rose the dog that actually shrank her cancer by 75%

Also looking forward to seeing what comes next for @paul_conyngham and seeing the eventual writeup from scientists involved @martinalexsmith , @PalliThordarson @DrAllavena .

AI finally did it. It cured cancer. Except, contrary to a lot I'm seeing out there, ChatGPT didn't cure a dog's cancer. Nor did other AI models. theverge.com/ai-artificial-… Read more in my latest for @verge

Ya know, the House of Mouse with the notorious and not-at-all-intimidating legal team...

I also have to highlight perhaps my favourite quote from the piece courtesy of @as_bates : “Also, the fly does not fly.”

Special thanks to @michaelandregg @as_bates @birchlse @TomMcClelland1 @aran_nayebi and @ShahabBakht for taking the time to speak with me.

Serious question… Is this a real fly? Taking on that big question for @verge theverge.com/ai-artificial-…

@paul_conyngham Hi. I'm a reporter working on a story about AI in medicine and biology. Would you be open to a brief chat, and if so what's the best way to reach you?

A lot of people have been asking if this can be done for their dogs and for people. I'm speaking with everyone involved to see what is possible here. If you would like to be involved, please complete the following Google form: bit.ly/4bkaowg

@HaydnBelfield omg I thought that was an H&M...
