Happy #FluorescenceFriday! I captured this shot of a group of embryonic macrophages expressing LifeAct and H2B migrating inside tissue. These cells can use lamellipodia, filopodia, or blebs to migrate, and are frequently switching between these different modes or combining them. So fascinating.

I had a ton of fun the other day talking with @nonresidentdesi.bsky.social and @scifri.bsky.social 's Flora Lichtman and Rasha Aridi about murderous microbes and the things that we are trying to learn from them. Happy for the opportunity to bring some new awareness to the world of protists!

Researchers like Ben Larson and Glen D’Souza are piecing together the world of killer microbes, including why they turn on each other and if their tiny weapons could be harnessed to fight disease. Listen to the podcast now: www.sciencefriday.com/segments/kil...

Deep-sea sponges survive in complete darkness in ways we didn’t know before

Beyond the sunlit ocean lies a vast abyss where organisms have to recycle every scrap available.

For years I've been looking for the right guest to do a pod on this. The car-sales model that is dictated by law in the US -- you must go to a dealership & suffer for hours in order to buy one -- is one of the most nakedly anti-social special interest giveaways in history. Needs to be killed dead.
