Not all sexual swellings signal fertility. Some signal strategy. In our new Current Biology paper, we show how gelada females “fake it” during male takeovers—and why it works.

Blue jays are always around here but I don’t always observe them. This one found a corn niblet and posed for my reference photo. Sketched it fast with 0.5mm 4B + 0.3mm 2B Pentel Graphgear, plus a blender to bring the forest floor into focus at the end. Jays mimic hawks. Wild. #birds #sciart #drawing

The race to churn out papers is a systemic problem.
Early career scholars are desperate to get more papers to compete in the academic job market. This can make it hard for faculty mentors hard to reduce their output unless they shrink their lab (which removes opportunities from next generation).
