A somber voice-over relays that the hatchlings are misguided by the nearby city lights.

Sea Otters Leave an Archaeological Record of Their Tool Use

Archaeologists learn about ancient humans by excavating and analyzing historical artifacts. While the use of tools was once thought to be a uniquely human trait, this is far from the case; many terrestrial animals, including chimpanzees, macaque monkeys, and even vultures use stone tools to hunt and gather food. For aquatic animals, however, these behaviors have been difficult to observe in the wild. One exception … Continue reading Sea Otters Leave an Archaeological Record of Their Tool Use

Scientists Grow Turtle Skin to Study New Virus

Thierry Work and a team of wildlife disease researchers are manufacturing reptile skin in the hopes of saving endangered turtles. A virus, ChHV5, has been infecting endangered green sea turtles, causing tumors to grown on the their skin and inside their bodies. The infection eventually weakens the immune system, and leads to death. Studying this virus proved incredibly difficult. Traditional methods of growing viruses to study ChHV5 in the lab … Continue reading Scientists Grow Turtle Skin to Study New Virus
