Bumblebee workers vary considerably in size, and body size affects which tasks individuals perform. "We expected that larger workers would be incubators, but we found to our surprise ...

Experience affects new neuron survival in adult brain; study sheds light on learning, memory

New evidence of 'human' culture among primates

...A strong case has already been made for great apes having a capacity for social learning, but until now there has been no evidence of material culture among the "new world" primates of Central or South America, which include Capuchins.
