We made the cover of this @CR_AACR issue!!! 🥳🥳🥳 Published Paper: aacrjournals.org/cancerres/arti… Rascore Website: dunbrack.fccc.edu/rascore/ @RolandDunbrack @DrexelMcbg @FCCCAcademics

Congrats to our stellar match class! We’re thrilled for them. A great group of future residents. @MSK_RadOnc @MSKCancerCenter #radonc #Match2026 @ASTRO_org

We are thrilled to welcome our new residents! What an exceptional group and exciting times ahead. Welcome to @MSK_RadOnc!! 🎉 #Match2026 #RadOnc #FutureLeaders

@kendallngarrett @UCSDRadMed @CWRUSOM Congrats! Was great working with you last summer. You are going to make an all star RadOnc!

Overjoyed to announce I matched at @UCSDRadMed for radiation oncology! I am so excited, and so grateful to all of the residents and attendings who supported and mentored me throughout this journey! I’m going home! ☀️☢️ #match2026

Big news: the thymus may be critical for adult health What if we missed something fundamental about the immune system? In two back-to-back papers in Nature, we show thymic health (AI on 30,000+ CT scans) links to longevity, disease risk & immunotherapy outcomes.

𝐈𝐧𝐭𝐫𝐨𝐝𝐮𝐜𝐢𝐧𝐠 𝐌𝐑-𝐑𝐀𝐓𝐄 A large-scale brain MRI dataset + report generation VLM, built with NVIDIA 100K studies from 80K+ patients, ~700K volumes paired with radiology reports We continue moving beyond narrow AI tools toward generalist medical intelligence

You probably have seen the headlines on the latest paper bashing AI. Our response to the Nature Medicine paper claiming ChatGPT Health under-triages 51% of emergencies is now on arXiv. Short version: the evaluation format drove the failure, not the models. Link below 👇

Thank you @anthropic for the award and recognition. I hope this hackathon will enable other builders that had their big idea in the back of their heads. The technological barrier between domain expertise and creating a working solution has never been smaller. @claudeai Code 1st Birthday & Hackathon showcase today in @SHACK15sf. Looking very much forward to meeting everyone!

Cardiologist wins 3rd place at Anthropic's hackathon. Out of 13,000 applications. Built in 7 days by Michał Nedoszytko MD. Coded day and night - in the hospital, in the cloud, while flying from Brussels to San Francisco. A few years ago, it would have been impossible for a doctor to build this alone in just a couple of days. AI changed that. The project is called postvisit.ai. It is an AI agentic care platform for patients. Including reverse AI scribe it is a companion that guides the patient from the moment they leave the doctor's office. Powered by the massive context window of Opus 4.6, it allows patients to explore their full medical history, connected devices, Evidence Based resources and external data sources — all in one place. Today, the barrier to entry has vanished; even a practicing physician can build an application from scratch.

Longtime listener; first time caller. Had a blast exploring a wide range of topics - from scaling laws to Paperboy (the Nintendo game) - with @arjunmanrai and @AndrewLBeam .

🧬🫁 Happy to share our new preprint! Genomic/transcriptomic correlates of response to tarlatamab in SCLC. We performed integrated whole-exome + whole-transcriptome sequencing in 12 tarlatamab-treated patients (+2 post-progression), small but mighty! medrxiv.org/content/10.648…
