The missing heritability question is now (mostly) answered

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

Intracellular competition shapes plasmid population dynamics
From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

Big news: I’m writing a book!!
I’ll be writing & illustrating a beginner’s guide to appreciating wildlife in cities/suburbs, & how all of us can make our neighborhoods better for those animals.
Thank you to my book agent @ericsmithrocks.bsky.social & the folks at Storey for believing in this book!

A cluster of, I think, earwig eggs (although I didn't see the mother, who typically would be guarding them). What I especially like are the micro-droplets of condensation; each egg is at most 1 mm., so the droplets are incredibly small. Shot at 2X, ten handheld images stacked. 🐙🌿📷 #Bugsky 🥚

The Bruce Museum in Greenwich, CT, has a new exhibit: Ants - Tiny Creatures, Big Lives. We went today, and here are some impressions. It’s not a massive exhibit, but well done and certainly worth checking out if you’re in the area. The exhibit runs through May 17.

I can attest this practice was common, and let me disabuse anyone who thinks practice went away because people realized the obvious unsafe working environment issues—it was Zoom that ended the conference hotel room interview.
If you are not in academia, you might not know this, but job interviews used to be held at conferences IN HOTEL ROOMS. Women candidates in a hotel room alone with often all-male committees. People sitting on beds! The horror stories I've heard.
I thing I sometimes thing about is that university departments were still doing job interviews in hotel rooms in the mid aughts

Pileated Woodpeckers are the largest woodpecker in North America and are nearly the size of a crow. They excavate deep into rotten wood to get at carpenter ant nests and leave behind rectangular holes. This is a female busy looking for food. 🪶

This study is WILD - some dinosaurs (reptiles) had hooves, and this is now the earliest known fossil of a hooved animal. Even crazier, mammals may have secondarily LOST their hooves through evolutionary adaptations (the origin of hooves is still kinda murky) www.science.org/doi/10.1126/...

Because international student enrollment is so often used as a cudgel in discussions about immigration, this is a good time to remind people that international students aren't taking up spaces for US students at state schools, they are paying full tuition that FUNDS SCHOLARSHIPS FOR US STUDENTS.

One of the highlights of a short trip to Yunnan last week – the Spot-breasted Parrotbill: an icon for functional morphologists, an insectivore with the 'wrong' beak (stubby like a seed-eater) which nonetheless makes ecophysical sense because it uses bite-force to snip through grass/bamboo stems

I suspect people don’t know that most scientific conferences charge many thousands of dollars to set up a sales booth, which is why the vending areas are full of boring corporate bullshit and none of the fun wacky artists you’d actually want to see there.
