From bird feathers to fruit skins, the natural world has two main ways of displaying colour: through pigment substances that provide selective colour absorption, or through structural colour – the use of microscopic structures to control light reflection.   Now scientists have devised a computer model that explains why the brightest matte structural colours in

Animals have been hibernating for a long, long time, a new study shows. Researchers have analysed 250 million-year-old fossils and found evidence that the pig-sized mammal relation, a genus called Lystrosaurus, hibernated much like bears and bats do today.   Finding signs of shifts in metabolism rates in fossils is just about impossible under normal conditions –
