Male Caspian terns are not only responsible for leading their young on their first autumn migration to wintering quarters, but they also have an important role in defending their young against possible threats. Here, a young tern (bottom right corner) is seen roosting on a stopover site together with its parent, which is seemingly not happy about the approach of a young common gull. (Petri Hirva)

Coastal Redwood trees stand at Muir Woods National Monument on August 20, 2013, in Mill Valley, California. A recent study found that redwoods have two distinct types of leaves — one for absorbing water and one for photosynthesis. The placement of the leaf types changes across their range depending on how wet or dry their conditions are. (Justin Sullivan/Getty Images)

Researcher Ashley Poust holds the fossilized lower jaw of Diegoaelurus, a bobcat-sized carnivore that lived 42 million years ago. Diegoaelurus was much smaller than the commonly known Smilodon, or saber-tooth cat, seen in the background. Smilodon evolved roughly 40 million years after Diegoaelurus went extinct, but both animals were saber-toothed, hyper-carnivorous predators, meaning their diets consisted almost entirely of meat.
