Scientists have designed a heat-insulating material made from wood that is both light and strong and made entirely from tiny, stripped-down wood fibers. The so-called nanowood, described in the journal Science Advances, could one day be used to make more energy-efficient buildings. It’s cheap and biodegradable, too. “Nature is producing this kind of material,” said senior … Continue reading This is ‘nanowood,’ an invention that could reduce humanity’s carbon footprint
