Pregnant people often struggle to sleep and now it turns out that disrupted sleep extends cockroach pregnancies by reducing the quality of the milk that feeds the developing young so they take longer to grow. Cockroaches need their beauty sleep too!

What you eat when you eat matters!

Diet during development vs adulthood affects survival, fertility, and stress resistance — differently in male & female fruit flies.
Same calories, different outcomes.

Congratulations to our Carmen Noske, who defended her M.Sc. Thesis on the sexual signals of a cursorial spider. She brought us several steps closer to identifying the elusive sex pheromone and the role of physical signals in this multimodal communication system. Great show and great data!

Lots of ppl are (correctly) critical of AI bc it's destroying the planet & when you ask it something it's usually wrong. But my biggest complaint is that the internet is now FLOODED with AI-generated sites about foraging and farming, two things I'm super into right now. It has literally killed ppl.

The arms of an octopus are multifunctional and they can even sense light. Chang & Hale recently showed that when light hits the skin of the arm, it sends a signal all the way to their brain suggesting this feature might help camouflage themselves
