Phys.org: ROP signaling: Exploring its origin at the dawn of multicellular plant life ROP signaling: Exploring its origin at the dawn of multicellular plant life If you look at the world around you now - at the plants, animals, and the people around you, it's easy to take for granted our multicellular existence. Life didn't always look like this. In fact, way ... Does anyone know of a eastern tree, suitable for zone 6, that has an interesting winter silhouette? I like the look of a black gum a few streets over, but I want to make sure that I do't over-look any other, possibly nicer ones, as this will probably be the last tree I ever plant. Thanks. Plants regulate their development with a distinct group of molecular players. ROP proteins, a group of plant-specific proteins, are known to control plant tissue formation. Now, Hugh Mulvey and Liam ...

A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding ... 'She loves me, she loves me not': Physical forces encouraged evolution of multicellular life, scientists propose
