The iridescence of marble berries and the clever, light-bending perforations of microalgae are some lessons from nature that scientists are drawing upon to create biodegradable glitter and makeup pigments, and bionic algae to use in lasers or to clean pollutants. Nature has spent millions of years evolving answers to problems. It has come up with ingenious solutions … Read more

The evolution of biodiversity: ever-increasing or did it hit a ceiling?

New findings are challenging the conventional view on this. Increasing knowledge on historical patterns of biodiversity … Read more
