“When participants used ChatGPT to draft essays, brain scans revealed a 47% drop in neural connectivity across regions associated with memory, language, & critical reasoning. Their brains worked less, but they felt just as engaged—a kind of metacognitive mirage.”🧪

I have a new preprint demonstrating a genome-architecture-aware approach to inferring species trees and introgression landscapes from a small number of genomes. If you are interested in phylogenomics, birds, or hybridization, this is for you! www.biorxiv.org/content/10.1...

We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen. 1/n

I’ve been asked about de-extinction a lot this weekend, especially whether it’s scientifically possible. No, it’s not, and Colossal has already been caught lying about their projects. Extinction is forever. We have to grieve and use that feeling to protect the future of life that is here now.

🚨 NEW PAPER! 🚨 Being an “internationally successful” scientist depends on English. But what if you also face gender & global inequalities? We show that women from the global South publish the same total # of papers but have 70% fewer in English language. Affecting their career possibilities.

Having a diffuse research group means that I rarely get to spend any time with my group in 3D. It was a great delight therefore to be joined by @collinbos.bsky.social @alicepetzold.bsky.social @njorisfleck.bsky.social and @clarakeusgen.bsky.social together in Bonn for the #SEH2025! 🧪🐸🦎🐍🧬

“fascist government controls media and bans dissent” is a straightforward description of what’s happening in the united states

Someone's pet cat with the native wild red squirrel it just killed. Most cat owners have no idea of, or don't want to know, how much wildlife is slaughtered annually by domestic or feral cats. But it runs to 10s, possibly 100s, of BILLIONS of animals per year, and is a serious driver of extinction.

I’m setting up a Discord server for young herpetologists, derived from an idea at #SEH2025. The goal is to create a space for quick help, collaboration, and networking. If you’d like to give input or get involved, let me know! #herpetology

#SEH2025 what a week! Plenty of great talks, lovely people and chats… Also presented a poster on our Grass Snake project in Berlin.

Hey #frog people! If you are using @inaturalist.bsky.social, please feel invited to the new „Frogs in Amplexus“ project! We try to collect all amplexi, (to be) recorded on iNat. So please consider to add your future amplexus observations, or such that you help identifying/correcting. #amphibians

Loving the Herp-Omics symposium at #SEH2025! Proud to see several members of my lab presenting here—my postdoc @alicepetzold.bsky.social presented and is one of the chairs! Up now, @clarakeusgen.bsky.social is presenting on the Bachelor’s thesis that she did with us.

And now @collinbos.bsky.social is presenting on mitochondrial genome reorganisation in microhylid frogs from Madagascar, and how we can explore it using off-target sequencing from target capture sequencing reads. 🧪🐸 #SEH2025

Meet the newest species of Brazilian flea-toad 🐸 Brachycephalus nanicus! 🐸 B. nanicus is <1cm long & dwells under the leaf litter in the cloud forests of Serro do Mar, southeastern Brazil I CT scanned this specimen for the osteological description Out today in Zootaxa: mapress.com/zt/article/v...

A wonderful first day of the #SEH2025 meeting today here in Bonn! Seeing my students presenting is especially gratifying; @clarakeusgen.bsky.social brought this absolutely beautiful poster. 🧪🐸

On my way to Bonn for the #SEH2025 23rd European Congress of Herpetology! I’ll be giving a plenary on Wednesday about miniaturisation. Really looking forward to seeing old friends and making new ones, and exchanging ideas across the field 🐢🐍🐸🧪

Rawr! 🐢

the first images that show up when you google specific frogs are just AI slop that looks nothing like them 😭

Yarrow's Spiny Lizard (Sceleporus jarrovii), Arizona. See the parietal eye? This third eye has a lens, cornea, & retina, but is not for image-forming. It senses light/dark to help regulate circadian rhythms, and may help the lizard avoid predators & assist with sense of direction. 🦎 #reptiles 👁️👁️👁️

One of our “green new scam” research grants that USDOT terminated focused on making transit infrastructure more resilient to more frequent and severe weather events. But “climate change adaptation” was too woke, obviously, and doing this research is clearly unnecessary

Been wandering the Kerala side of the southern Western Ghats for almost a week, and I’ve finally met, quite possibly, the most stunning frog on the planet. Photos from my phone do not do this frog any justice. Galaxy Frog 𝘔𝘦𝘭𝘢𝘯𝘰𝘣𝘢𝘵𝘳𝘢𝘤𝘩𝘶𝘴 𝘪𝘯𝘥𝘪𝘤𝘶𝘴

New paper on long-term lizard declines.🦎 Abundance highest in wet yrs (we haven't had many!). Some species abund related to lagged effects from vegetation cover, emphasizing the delayed response of biotic communities to ecosystem changes. #urban #herps 🌎 doi.org/10.1002/eco....

Excellent piece. LLMs can be useful for automating tedious tasks, but for tasks that require rigour and critical thinking, such as peer review, it's problematic on multiple levels.
