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/

Meet the carrier crab, an animal that brings its defence wherever it goes. Its back legs are specially adapted to hold anything it can wedge between itself and danger: a bit of dead coral, seaweed, a broken shell. Sometimes, though, that shield is alive – like this jellyfish! 🛡️🪼👇

Today's #EarthOptimism #OceanOptimism story is threatened sea turtles got cold-stunned in the winter storm off Florida, but have been rescued. They'll be rehabbed and released and have a good chance of full recovery and a long sea turtle life. 🧪🦑🌎

Imagine our profession was built so that you could advance your career without moving all the time. Isn't this a huge piece of the equity and access problem? Yes, it is.
Needing to move is a huge barrier to broadening representation in the sciences
Science will be more inclusive and equitable when we stop expecting people to uproot their lives every few years

Retention of blue‐green cryptophyte organelles by Mesodinium rubrum and their effects on photophysiology and growth

Coffinfishes (Family Chaunacidae), from the deep-sea, have two enormous gill chambers on either side of the head that can hold a huge volume of water. The fish inflates by ~30% body volume, and then it holds its breath until it is ready to exhale. #marinelife www.youtube.com/watch?v=iBGt...
