Queria começar a thread dizendo que pessoalmente não tenho nada contra a Profa. Dra. Tatiana Sampaio. Também digo que não vou FOCAR a polêmica do uso ou não de placebo no grupo controle, meu foco é na visão panorâmica do caso no contexto de desenvolvimento de fármacos.

Good thread about thinking about audiences when giving a talk.
Happy to end the year sharing my thoughts on this paper: "Body size and litter size as predictors of pouch presence in marsupials", by Casali et al. (2025). Digest available at doi.org/10.1093/evol...
Schematic drawing of a curious female Didelphis albiventris observing its young in the pouch.
When we think of marsupials, the first thing that comes to mind is the presence of a pouch. But despite this striking anatomical feature, not all marsupials have it. What factors determine its presence or absence?

Very well done, timely, and complete report published by @universitypress.cambridge.org about the future of academic publishing. I had the opportunity to be interviewed for it and I highly recommend everyone to read it. Important messages here

A fossil of a pterosaur with text: Pterosaur died with belly full of plants—a fossil first. New discovery confirms the long-debated hypothesis that the ancient winged reptiles ate plants
About 120 million years ago, a pterosaur fell from the sky and died in a pond. A layer of sediment washed over it, preserving not only its skeleton, but also its stomach.
The resulting fossil is the first pterosaur ever found with a belly full of plants. #NationalFossilDay https://scim.ag/4hbaedc
A graphical history of mammalian species-group name descriptions since the start of zoological nomenclature on 1 January 1758, incorporating all 28,382 available names (including preoccupied, replacement, and suppressed names) and 6,759 names currently recognized as valid species in MDD2.
Type locality locations for species-rank mammal taxa described from 1 January 2000 to 15 August 2024.
It's crazy to think that while heading toward 9 billion people on Earth, we ere still undescribed (and know nothing about) hundreds to maybe thousand mammalian species

I relate 100%. Learning to play bass after finally getting a job in academia (but no one to play with in a new city). :(
you should be using pak
Ever run `install.packages()` and wish it were faster, smarter, and more reliable?
The {pak} package speeds things up with parallel downloads, dependency solving, and reproducible installs.

Featuring several mentions of this excellent paper www.cell.com/trends/ecolo... by our colleague Ronald Jenner.
As we're all taught, you can (usually) only directly date the age of a rock if it cooled from lava.
But here, scientists have dated dinosaur eggs, using uranium-lead ratios in the calcite. Hugely exciting, maybe groundbreaking.
My take @science.org

Some 241 million years ago in what is now England, a tiny, lizardlike creature had teeth well suited for snapping after insects.
Now named Agriodontosaurus helsbypetrae, this extinct reptile may be the oldest of its kind ever found. https://scim.ag/3V75MC5

Water anoles take a bubble of air down when they submerge, which they breathe like a tiny scuba tank, and now @lindseyswierk.bsky.social & co reveal that the reptiles may also be using the bubble like a gill, to breathe oxygen directly from the water

Thumbs are cool and all, but have you ever thought about how important thumbnails are? They just might have been the key to rodents' evolutionary success. That and more of the best from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪
Jokes on you, that's his treadmill
Thank you very much! ☺️
Me too! 😂
thumbs up!!! 👍
Our paper on rodent thumbnails is out! Big team effort, powered by museum collections. Turns out, nails can reveal a lot about rodent evolution. Shoutout to Dr. Gordon Shepherd for the wild idea to study rodents thumbs!
