Jellyfish aren’t just a menace—they may very well have the power to save the planet. The marine creatures have long been studied for their potential to help combat major diseases from cancer to Alzheimer’s, but now they can help us with something that affects everyone on the planet: renewable energy. That eerie jellyfish glow that creeps out wayward swimmers could power your next home. That glow is caused by the green fluorescent protein (GFP), which, as the name suggests, fluoresces under UV light as it absorbs photons and emits electrons. It is this property that made the GFP so popular with medical researchers, who use it to mark other proteins, some of them associated with different diseases. Others help scientists map different parts of an organism. Back in 2010, Swedish scientists experimented with GFP as a material for a new type of solar cells that are both cheaper and […]
