GitHub - hadley/genzplyr: dplyr but make it bussin fr fr no cap dplyr but make it bussin fr fr no cap. Contribute to hadley/genzplyr development by creating an account on GitHub.

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....

genzplyr is dplyr, but bussin fr fr no cap.

I am being asked to tell my department which pieces of lab equipment should be supported with backup power because they expect rolling blackouts and brownouts in 2026 due to increased energy demands from AI. In case you're wondering how my day is going.

Sometimes, it's survival of the pluckiest. You'd think a lizard that lost a limb would not survive long. And yet... Now a 🧵of adorable lizards living their best life. 🧪🦎

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.

Historical Prevalence of the Amphibian Chytrid Fungus (Batrachochytrium dendrobatidis) in West Africa Abstract: . The chytrid fungus Batrachochytrium dendrobatidis (Bd) is implicated in global declines and extinctions of amphibian species. Although Bd is found on all continents where amphibians persis...

Excited to share that our new chytrid paper is out in Herpetologica! We find evidence that West Africa may not be the ‘safe haven’ for amphibians it was once thought to be. 🦠🐸

Two caecilians in the shape of a double helix.

My first first-author paper came out yesterday online-first in #Oecologia! We reported that neotropical swollen-thorn acacias increased their investment in mutualism with ants during an El Niño drought event. Mutualism may indeed be strongest during tough times.

It was an honor to facilitate sessions at the #SRI2025 Congress with @gsscholars.bsky.social, @belmontforum.bsky.social, and @futureearth.bsky.social! My heart is full after catching up with STRI friends, making new friends within the GSS community, and learning how to live in harmony with Earth 🌎.

It's a worm... It's a snake... It's a caecilian! I just wrapped up my very first field season in São Tomé and Principe 🇸🇹. Caecilians, grilled fish, and fresh cajamanga juice.. pretty sweet place to do fieldwork I gotta say. @uh-ecoevo.bsky.social

And PIs, don't tell your students/postdocs to do it, even if *you* did and were okay in the past! They may not feel like they can push back if they're not comfortable, and the stakes have gotten a lot higher.

Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with ‘agency priorities’.

BREAKING: NSF has frozen all grant funding, as of yesterday. It's unclear when they will resume funding awards, or why the pause has been put in place. www.nature.com/articles/d41...

A photo of PhD student John Nguyen. Text on the photo reads "Investigating the ecology and evolution of complex phenotypes in reptiles and amphibians"

@johnv-nguyen.bsky.social spent a year in Panama with the Smithsonian, investigating color morphs in female anoles. His NSF RaMP Fellowship research uncovers the genetic and ecological drivers of phenotypic diversity in these charismatic lizards. Manuscript in progress!
