Mario Molina (1943-2020) was a Mexican-American chemist known for his pioneering work in atmospheric chemistry and environmental science. Born in Mexico City, Molina’s research focused on understanding the depletion of the ozone layer caused by chlorofluorocarbons (CFCs). Along with F. Sherwood Rowland and Paul Crutzen, Molina demonstrated how CFCs released into the atmosphere could lead … Read more
The Neanderthals, our closest relatives in the hominin evolutionary lineage, have long captured the imagination of scientists and the public alike. These ancient humans, who inhabited Europe and parts of Asia for hundreds of thousands of years, share a common ancestor with modern humans and coexisted with our species for millennia before eventually going extinct … Read more
The fascinating world of orchids just got a little more intriguing. Researchers from the University of Tokyo have stumbled upon a first: an orchid species pollinated by gall midges, a tiny fly species.
