You're watching a sand bubbler crab hard at work. And bubbler crabs have one job: make balls. Lots of balls. With your mouth parts. They're filter-feeders/detrivores, combing through damp sand for microscopic food & the balls let them organize the "cleaned" sand so they don't nom it twice.

How do nuclear compartments form inside cell nuclei? We show RNA glues certain loci together to form a nuclear compartment. This involves special GC-rich regions of highly expressed genes that also associate with nuclear speckles, but interactions between these loci are independent of speckles!
