Green Sea Slug Is Part Animal, Part Plant
SEATTLE — It’s easy being green for a sea slug that has stolen enough genes to become the first animal shown to make chlorophyll like a plant…
The slugs can manufacture the most common form of chlorophyll, the green pigment in plants that captures energy from sunlight, Pierce reported January 7 at the annual meeting of the Society for Integrative and Comparative Biology. Pierce used a radioactive tracer to show that the slugs were making the pigment, called chlorophyll a, themselves and not simply relying on chlorophyll reserves stolen from the algae the slugs dine on.
Most of the time the brain works as it ought to: limbs move, memories are retrieved and experiences processed. But occasionally things go awry.
In tip-of-the-tongue experiences, for instance, words suddenly and perplexingly go missing only to reappear seconds or minutes later. Another brain quirk –déjà vu – confirms the fallibility of memory. Now two new studies have shed light on both phenomena.
“Night owls who stay up late and then lie-in the next morning can actually work harder and for longer than go-getting early birds, claim scientists.”
