Let it rain! New coatings make natural fabrics waterproof

Fabrics that resist water are essential for everything from rainwear to military tents, but conventional water-repellent coatings have been shown to persist in the environment and accumulate in our bodies, and so are likely to be phased out for safety reasons. That leaves a big gap to be filled if researchers can find safe substitutes.

Path to zero emissions starts out easy, but gets steep

Carbon dioxide emissions from human activities must approach zero within several decades to avoid risking grave damage from the effects of climate change.  This will require creativity and innovation, because some types of industrial sources of atmospheric carbon lack affordable emissions-free substitutes, according to a new paper in Science from team of experts led by University of California Irvine’s Steven Davis and Carnegie’s Ken Caldeira.

Territory Holders and Floaters: Two Spatial Tactics of Male Cheetahs

Scientists of the Leibniz Institute for Zoo and Wildlife Research (Leibniz IZW) in Berlin analysed the spatial behaviour of cheetahs. They showed that male cheetahs operate two space use tactics which are associated with different life-history stages. This long-term study on movement data of over 160 free-ranging cheetahs in Namibia has now been published in the scientific journal ECOSPHERE.

Major Study Reveals Great Barrier Reef’s 30,000-Year Fight for Survival

A landmark international study, recently published in Nature Geoscience, shows that the Great Barrier Reef has suffered 5 death events in the last 30,000 years. The groundbreaking study of the world’s largest reef system, involving the participation of Juan Carlos Braga Alarcón, a Full Professor at the UGR’s Department of Stratigraphy and Palaeontology, reveals that these events were driven mostly by variations in sea level and associated environmental changes.
