This week, researchers at the University of Albany reported an extreme size difference between early human males and females, suggesting intense competition among males. Krill are so overfished in Antarctica this year that the Commission for the Conservation of Antarctic Marine Living Resources may trigger an unprecedented early closure of the fishery. And researchers report early behaviors that signal upcoming divorce between paired songbirds long before the breeding season.



Summary

This week’s research highlights stark disparities in the natural world. University of Albany researchers found significant size differences in early human males and females, potentially indicating intense male competition. In Antarctica, severe overfishing of krill might force an unprecedented early closure of the fishery by the Commission for the Conservation of Antarctic Marine Living Resources. Meanwhile, scientists have identified early behavioral signals in songbirds that can predict divorce long before breeding season, offering insights into relationship dynamics.
