I'm making a list of #rstats packages for data validation. I've got {pointblank} and {assertr}. What am I missing?

Sometimes, clinical journal clubs need PowerPoint. And sometimes, they need Positron.

'Universal' cancer vaccine heading to human trials could be useful for 'all forms of cancer' A new mRNA-based vaccine triggers a response from the innate immune system to help arm the body against cancer, a mouse study finds. It's now in early human trials.

Just incredibly shortsighted is the nicest thing one can say about defunding research on mRNA vaccines.

What good is FDA’s AI tool if HHS takes an entire class of vaccines with unprecedented efficacy completely out of circulation?

No amount of AI can overcome bad health policy.

The biggest difference between AI and nephrology is that one studies humans in the loop and the other studies loops in the human.

AI to Advance Patient Safety Summit Report How do we prioritize patient safety in AI efforts?

AI is transforming patient safety, but tech alone isn’t enough. During our recent summit, leaders explored how to lead with safety — before speed.

We were honored to host a distinguished delegation from the Ministry of Maharashtra this week.

Engaging with international leaders and health innovators is central to our mission of advancing and scaling global health solutions.

Today at #WTC2025:

A patient with type 1 diabetes underwent transplantation of genetically modified allogeneic islet cells with no immunosuppression. The results of this study support the concept of immune evasion by these modified cells. Read the Brief Report: nej.md/3TXVgwp

Just kidding I think you’re right it’s a cursor or some weird ligature thing.

Ah yes, the mustachioed walrus operator.

:= is the “walrus operator” that data.table uses to modify the data table in place.

R and the Model Context Protocol The newly released mcptools package makes coding assistants better at writing R code and applications built with ellmer more powerful.

mcptools, a package implementing the Model Context Protocol in #rstats, is now on CRAN!🌉

We see significant opportunity with MCP and, at the same time, want to note that it's still a nascent ecosystem with serious security risks. www.tidyverse.org/blog/2025/07...

ellmer 0.3.0 The newest version of ellmer introduces a simpler `chat()` interface that can works with any provider, a bunch of improvements to tool calling, and a handful of smaller quality of life improvements.

🐘 ellmer 🐘 makes it easy and fun to use LLMs from #rstats, and 0.3.0 is out now. Read about the new streamlined chat() function, improvements to tool specifications, and more at www.tidyverse.org/blog/2025/07....

The most novel thing in the world is a good book.

Moses holding up the 11th commandment to a group of tech bros at the Equinox on Mt Sinai

Thou shalt, if thou writest a medicinal treatise applying thine chosen algorism of #machinelearning or #artificialintelligence, use the word "leveraging" in the title to make manifest the newness and preeminence of thy research.
AMEN.

Ok but can the bar on the left run Doom?

Agreed.

The biggest pro in Python is a lower opportunity from needing to teach students the language basics, which they have usually learned elsewhere already.

But if you care about which packages they use and prefer ibis and plotnine over pandas and matplotlib, then the difference becomes minimal.

The timestamps tell the real story.

(And now we gotta bring all those packages to Tidier.jl for #julialang)

I ran an #rstats lab for many years before our foray into #pydata, so wouldn’t say my experience is super generalizable. But going back to play with R and seeing improvements to wasm and shinylive, ellmer, ragnar, vitals, and the entire tidy ecosystem reminded me just how batteries-included it is.

I’m much more comfortable with vibe coding (if needed) for a functional language with piping, where everyone agrees on which objects are required, and there’s a lower chance of bad design decisions being made. The resulting code is much less likely to need dramatic refactoring.
