We are all super happy and proud to see our work on the function and evolution of the #cephalic #furrow published in @nature.com. Let me say a few things about the background and history of this work on the #Evolution_of_Morphogenesis (1/12)

Thrilled to share our new paper!
With @tomtom-auer.bsky.social team, we asked how #evolution reshapes what animals #eat to match their ecological niches. Using pan-neuronal Ca2+ imaging, we show that the changes are in how the brain processes #taste.

New research from EMBL and @Stanford shows how centromeres retain their function despite their rapid rate of change, and the evolutionary constraints that govern this process.

Some archaea—an ancient group of microorganisms—have an entirely novel genetic code, according to a new study in Science.
The findings expand our understanding of how alternative genetic codes evolve and hint at new molecular tools for biotechnology applications. https://scim.ag/4omApQ7

Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.
