Instead of analyzing days, weeks, or months of recorded footage for animal behavior studies, researchers can now turn the task over to an open-source algorithm capable of picking up even subtle actions. Not only could this save researchers time, it could also improve the lives of animals in zoos, the wild, and the lab. Animal behavior: Animals can't talk to humans (yet), but they can communicate through their behavior -- an animal that's eating less than normal may be experiencing depression or illness, for example. Much of what we can learn from animal behavior requires that we study them for an extended period of time. Being able to analyze animal behavior is hugely important for both people and animals.
