3D structure of the social amoeba genome sheds light on the transition to multicellularity

Each cell of the human body contains two meters of DNA. The whole secret lies in the intricate three-dimensional arrangement that allows DNA strands to be efficiently organized and compacted within the cell.

Biologists study trade-offs of microscopic predators

The drama of predators vs. prey—hunting, stalking, fleeing—isn't limited to the animal kingdom. Underneath our feet, hungry amoebae in the soil pursue and eat bacteria in a microscopic wild kingdom. But being a predator has its own costs, and that's as true for amoebae as it is for lions or wolves.

Costs of being a diet generalist for the #protist predator #Dictyostelium discoideum https://www.pnas.org/doi/10.1073/pnas.2313203121

"The #amoebae prey on a very diverse group of #bacteria. But when they switch from one bacteria to another, there's a physiological cost."

Oh c’mon! I know I see #Dictyostelium everywhere, but I’m not imagining the likeness this time, right?!?

For comparison to the real thing, see here: https://www.scientificamerican.com/article/what-is-it-social-cells/

Good morning Dicty lights, she whispers to herself each day at work

Migrating here from a different server, so here’s an #introduction repost:

My research focuses on #cooperation and conflict. I work with #Dictyostelium — a soil #amoeba where cells #cooperate and sacrifice to build multicellular fruiting bodies. A system where there can be a benefit to selfish behaviors. I try to understand how these amoebae make their society work. (1/2)
