African wild dogs (Lycaon pictus) travel incredibly long distances to search for a mate and new places to breed. They typically embark on these mammoth treks as young adults and often face numerous hazards along the way. ...
In both biological and engineered systems, cells and sensors must make sense of noisy, changing signals to function. However, collecting and using this information consumes valuable energy. A new study, published in Physical ...
Some female animals living in groups raise offspring that are not their own, sometimes without reproducing themselves. While the behavior of cooperatively breeding species is well documented, some aspects remain poorly understood.
