Like a kraken rising from the depths (or a cuttlefish emerging from the sand), Cephalopod Week is back! Every year, Science Friday spends a week honoring the mighty, clever, mysterious cephalopod. This year, Field Museum curator Janet Voight joins Ira and SciFri’s chief cephalopod cheerleader Brandon Echter to talk about the unusual and brainy behaviors of these creatures—including a squid that uses bioluminescent bacteria to camouflage itself—and whether cephalopods could someday become a model organism as ubiquitous in labs as mice and fruit flies.

The story of the dinosaurs is one that’s been told over millennia. But within the last few decades, what we thought we knew about their rise and fall is being rewritten.

Plus: A look at the latest science stories of the week, and a look at why Chicago Park District may shut down half of its outdoor drinking fountains.
