Ultraviolet (UV)-absorbing compounds from natural sources are attracting interest as potential ingredients for cosmetics and other protective materials. Saclipins A and B are unusual UV-absorbing oxylipins produced by the edible freshwater cyanobacterium Aphanothece sacrum, known in Japan as Suizenji-nori. Although these compounds show promising UV-absorbing and other functional properties, their low natural abundance and poorly understood biosynthesis have limited efforts to use them more broadly.

Toothless 'hell chicken' dinosaur may have had a taste for fruit

While many dinosaurs were fearsome predators with razor-sharp teeth, others were peaceful herbivores munching on plants. We can now add a new species to the list of plant-eaters, Infernogallus jamesi. Its name means hell chicken, and its fossilized remains were found in the Hell
