A team of researchers led by scientists from the American Museum of Natural History has found that catsharks are not only able to see the bright green biofluorescence they produce, but that they increase contrast of their glowing pattern when deep underwater.

New research based on high-resolution x-ray movies reveals that despite having extremely underdeveloped muscles and wings, young birds acquire a mature flight stroke early in their development, initially relying heavily on their legs and wings to work in tandem to power the strenuous movement.

Fossils of a 13-million-year-old extinct crocodilian from the Peruvian Amazon suggest that South American and Indian species evolved separately to acquire protruding, “telescoped” eyes that helped the animals conceal their bodies underwater while scanning the river’s edge.

New research suggests that humans became the large-brained, large-bodied animals we are today because of natural selection to increase brain size. The work, published in the journal Current Anthropology, contradicts previous models that treat brain size and body size as independent traits responding to separate evolutionary pressures.

The Hawaiian Islands have long been thought to support just one endemic land mammal in the archipelago’s brief geologic history, the Hawaiian hoary bat. But new fossil evidence indicates that a second, very different species of bat lived alongside the hoary bat for thousands of years before going extinct shortly after humans arrived on the islands.

Dinosaurs never really vanished from Earth. Most did go extinct, but their evolutionary legacy lives on all around us, in birds. The American Museum of Natural History’s new exhibition Dinosaurs Among Us will highlight the unbroken line between the charismatic dinosaurs that dominated the planet for about 170 million years and modern birds, a link that is marked by shared features including feathers, wishbones, enlarged brains, and extremely efficient respiratory systems.

New research suggests that the feeding strategy of Kolponomos, an enigmatic shell-crushing marine predator that lived about 20 million years ago, was strangely similar to a very different kind of carnivore: the saber-toothed cat Smilodon.

Three years after its explosion, a type Ia supernova continues to shine brighter than expected, new research finds. The observations suggest that the powerful explosions produce an abundance of a heavy form of cobalt that gives the heat from nuclear decay an extra energy boost.
