A new study of the oldest known bird, Archaeopteryx, shows that some of birds’ weirdest mouth features—like extra tongue bones, a sensitive beak-tip, and fleshy “teeth” on the roofs of their mouths—date all the way back to the Jurassic Period. These features, which are still present in most living birds, hint that being extra-good at finding, grabbing, and processing food might be key to a life on the wing.
Contrary to expectations, wetlands do not need to be completely flooded to provide the greatest climate benefit. Instead, the water table should be below the soil surface and remain stable, according to a new study from the University of Copenhagen. The greenhouse gas methane and microorganisms in the soil are a game changer.
Iron-rich sediments transported by icebergs from West Antarctica failed to support algae growth in the Southern Ocean, because the iron was highly “weathered” and not readily bioavailable to algae—thus reducing the ocean’s carbon dioxide uptake.
