A leaf that cracks seawater into hydrogen and eats poison for lunch

A single leaf, flattened into a panel, is now cracking seawater into hydrogen and eating hydrazine for lunch. Researchers at Nanyang Technological University in Singapore built a solar-powered device that mimics how leaves harness sunlight to drive chemical reactions. The result is hydrogen fuel pulled from the ocean while simultaneously breaking down a highly toxic industrial pollutant. That is a two-for-one deal so elegant it feels like cheating. Electrolysis is usually energy-intensive and wastewater treatment is a separate, expensive headache. This thing handles both at once. It is early, and the leap from lab bench to deployment is long, but the logic is feral and clean. If you are still processing how weird it is that your next screen might be sewn into your sleeve, this leaf might be the harder pivot.
