Ester Gaya, formerly a postdoc in the Lutzoni Lab and now a Research Leader at the Royal Botanic Gardens, Kew, has published some of the research she did at Duke.  "The adaptive radiation of lichen-forming Teloschistaceae is associated with sunscreening pigments and a bark-to-rock substrate shift" appeared in the Proceedings of the National Academy of Sciences DOI:10.1073/pnas.1507072112.  The sunscreen produced by the Teloschistaceae enabled them to diversify from shady to warm and sunny climates, leading to an explosion of species about 100 million years ago.  Congratulations to Ester and Francois!  We are looking forward to newer and better sun protection products!
