A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.
Independently gating ion channels typically act fast within milliseconds, but cooperative interactions within a cluster of channels allow for a memory of previous electrical activity for several seconds.
Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.
By integrating theoretical and empirical approaches, the results show that linking abiotic factor and biotic interactions on the niche width will be critical for understanding species-specific responses to climate change.
The regulatory programs governing skeletal muscle regeneration that are controlled by Klf5 in cooperation with MyoD and Mef2 provide a potential avenue for intervention into muscle regeneration through modulation of Klf5.
