One of my grant applications asked for a project graphic so I had to oblige

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.

Evolutionary and ontogenetic shifts from aquatic to terrestrial light environments in frogs provide new insights into the vertebrate phototransduction cascade https://www.biorxiv.org/content/10.1101/2025.10.31.685797v1

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.

‘Pirates’ of the Caribbean: The luck and pluck of three-legged lizards Researchers from Washington University in St. Louis and the Georgia Institute of Technology study lizards who have lost limbs to understand how omnipresent the forces of natural selection can be, and ...

Evolution is survival of the fittest, right? Sometimes.

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.

Please share with anyone who cares about NSF support for graduate students and take 30 seconds to sign and leave a comment.

The deadline for the 2025 Graduate Research Fellowship Program is about one month away and literally no one can apply. #NSFGRFP

I yearn to solely frolick in the woods and make art. But until then... this will do.

Finally got around to uploading some of artwork to my website! Tbh, this is how I've been keeping the PhDemons at bay (best viewed on desktop): www.johnvnguyen.com/art

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. 🦠🐸

2025 Rad Awards: Dr. Sarah McAnulty Philadelphia biologist Sarah McAnulty brings science to the masses in classrooms, through burlesque, at meet-ups and on telephone poles

Philly squid biologist @sarahmackattack.bsky.social brings science to the masses – in classrooms, through burlesque performances, at forest meet-ups and on telephone poles. Meet one of our nominees for “Rad Girl of the Year.” 

Thanks Kelly! Happy to drop some off whenever I'm in Austin 😉

Thanks Bella! I can send you some once I print them 🤩

Two caecilians in the shape of a double helix.

I'm not procrastinating.... making #Pride caecilian DNA stickers is a requirement of my dissertation. Schistometopum thomense and S. ephele, the iconic duo of my PhD work.

Swollen-thorn acacias increased their investments in resident ants during an El Niño event - Oecologia Species interactions are frequently context-specific. Climate fluctuations can inflict stress on individuals, inducing plasticity in their behavior or changes in resource allocation. Obligate mutualis...

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...

@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!
