Observing proteins and cells in the wild
...ime molds - which typically exist as single-celled creatures - protect themselves by coming together to form one slug-shaped, multicellular organism. Scientists know that the starved cells possess the ability to instruct other nearby cells to take shape around them, while non-starved cells do not. However, the...Multitasking genes manage related traits in plants
...f related traits." Scientists have understood that creatures evolve to optimize their ability to survive and reproduce, ultimately building a plant or animal better adapted to its environment. In plants, this can be seen in the size and proportions of a flower. Flowers are serious business in the plant world, ...UC Berkeley, Joint Genome Institute target chloroplasts for clues to green plant evolution
... most people assumed. Rather, these many-segmented creatures emerged from the ocean earlier than insects. Crustaceans - crabs and lobsters - are more closely related to insects than are millipedes and centipedes, he said.
