Scientists from the Natural History Museum, London (United Kingdom), and the ESRF, the European Synchrotron, Grenoble (France), have found that some pollen has survived mass extinctions thanks, in part, to its nanofoam wall structure. This may explain why the survival of certain plants. It is the first time scientists have described a biological nanofoam structure. Their results are published in Science Advances.
