Spiny dogfish blood contains a hormone long thought absent in sharks
Cortisol is a hormone that helps humans and many other animals regulate their energy use and respond to changing conditions. For a long time, sharks and rays we...
Maxwell's demon learns to turn concealed information into usable energy for microscopic systems
Since its introduction more than 150 years ago, the thought-provoking idea of Maxwell's demon has profoundly shaped our understanding of the relationship betwee...
Replanted landscapes can look restored while soil fungi still lag behind
With up to 75% of the world's soils degraded, restoration projects try to reestablish functional and biodiverse environments to secure adequate food production,...
Finding their sense of direction: Cell movement helps tissues establish polarity
From the hairs on our arms to the microscopic sensory structures of the inner ear, many tissues in the body are built with a clear sense of direction. To build...
Glowing liquids could help protect products from counterfeiters using distinctive ultraviolet light signatures
