Thanks, @rockefeller.edu , for another amazing #talkingscience! I and the students I brought had a blast learning about dolphin communication from Dr. Magnasco and all the outstanding staff!

Great new paper!
Many stinging wasps, bees, and ants have controlled the sex of their developing eggs for millions of year using an ancient segment of their genome- always the same segment- but what's weird is, *the exact DNA sequence of that segment doesn't seem to matter*.

New work from @miyapan.bsky.social and our team, bringing ant, bee, and wasp labs together. @chuanxinyu.bsky.social shows that the ANTSR locus we discovered in ants has determined sex for 150+ My across bees and stinging wasps 🐜🐝, despite virtually no sequence conservation 😮 doi.org/10.1073/pnas...

Most birds molt a few feathers at a time. But some species, like the Northern cardinal, do away with all of their head feathers at once. Comment "✋🏽" if you've seen a bald cardinal before. Comment "👎🏽" if you haven't and this really weirds you out. #ChristmasBirdCount

The paradox of providing students with precise rubrics for writing assignments like a traditional paper is that the rubric becomes a perfect prompt for LLMs. But if you don't give a detailed rubric, they can claim they weren't sure what to do or not do. #philtech #philsky

Part of the problem is the way We have treated scientific discovery as if it is made by brilliant men.
All science is built on the science that came before. It is collaborative in multiple ways.
All attempts to credit a single scientist with THE crucial discovery are flawed.

Crowding more proteins per cytoplasm unit volume would hamper processes such as diffusion, which is already about ten fold slower inside the cell than in pure water.

4) “the complexity of biological phenomena is an argument for the use of mathematical methods rather than against it. In the case of a simple phenomenon we may hope to understand it without the use of mathematics, by simple inspection. But in a complex case we are left hopeless without mathematics.”

When we hear about a lone scientist who made groundbreaking discoveries on their own, it’s usually erasing the truth that science is a team sport, and field research builds on the local knowledge and expertise of the people that live there (8/10)
