In an amazing achievement akin to adding solar panels to your body, a northeast sea slug sucks raw materials from algae to provide its lifetime supply of solar-powered energy, according to a study by Rutgers University-New Brunswick (RutUni) and other scientists. It’s a remarkable feat because it’s highly unusual for an animal to behave like a plant and survive solely on photosynthesis. The broader implication is in the field of artificial photosynthesis. That is, if the researchers can figure out how the slug maintains stolen, isolated plastids to fix carbon without the plant nucleus, then maybe the team can also harness isolated plastids for eternity as green machines to create bioproducts or energy. The existing paradigm is that to make green energy, we need the plant or alga to run the photosynthetic organelle, but the slug shows us that this does not have to be the case.
