The hidden microbial communities that shape health in space‎

Microorganisms live in biofilms—the equivalent of microbial "cities"—everywhere on Earth. These city-like structures protect and house microbial communities and play essential roles in enabling human and plant health on our planet. Now, a new Perspective article published in npj Biofilms and Microbiomes sets out a path to uncover the role of biofilms in health during long-duration spaceflight, and how spaceflight research can reshape our understanding of these microbial communities on Earth.

Bats, bushbabies and aardvark edge closer to extinction in southern Africa‎

A new list of threatened mammals in South Africa, Lesotho and Eswatini shows that 11 more species have edged closer to extinction since 2016. Those that have joined the International Union for the Conservation of Nature's regional Red List for mammals at risk are: Lesueur's hairy bat, the laminate vlei rat, the thick-tailed bushbaby, the aardvark and the African straw-colored fruit bat. The Namaqua dune mole-rat showed one of the sharpest declines, jumping from Least Concern to Endangered. Joseph Ogutu is a statistician who researches collapsing wildlife populations in Africa. He explains that of the 336 mammals assessed, 70 are now threatened and 42% of the mammals only found in South Africa are at risk of extinction.
