A seismically induced onshore surge deposit at the KPg boundary, North Dakota [Earth, Atmospheric, and Planetary Sciences]
The most immediate effects of the terminal-Cretaceous Chicxulub impact, essential to understanding the global-scale environmental and biotic collapses that mark the Cretaceous–Paleogene extinction, are poorly resolved despite extensive previous work. Here, we help to resolve this by describing a rapidly emplaced, high-energy onshore surge deposit from the terrestrial Hell Creek…

Rwanda's gorillas have figured out where to find their sodium fix—but it's dangerous
Mountain Gorilla conservation in Rwanda is a great success story. A number of extreme conservation measures – like daily monitoring and protection, veterinary interventions and controlled ecotourism – have enabled the population to bounce back after a precarious low in the 1960s and 1970s that was brought about by habitat destruction and poaching.

As climate change erodes US coastlines, an invasive plant could become an ally
Many invasive species are found along U.S. coasts, including fishes, crabs, mollusks and marsh grasses. Since the general opinion is that invasives are harmful, land managers and communities spend a lot of time and resources attempting to remove them. Often this happens before much is known about their actual effects, either good or bad.

Three ways cities can help feed the world, without costing the Earth
Climate change is underway, and human activities such as urbanisation, industrialisation and food production are key contributors. Food production alone accounts for around 25% of global carbon emissions. Ironically, the changing weather patterns and more frequent extreme weather events resulting from climate change also put the world's food supplies at risk.

Why Blackwater cannot be the future of U.S. warfare
