In eusocial superorganisms like leafcutter ant colonies, labor is divvied up according to body shape and size, but PIK Professor Shelley Berger and her team discovered that molecular signals can override that blueprint. Their findings reveal how simple neuropeptides can reprogram ant behavior, reshuffling roles in nature’s most disciplined workforce.

What can ants and naked-mole rats teach about societal roles?
PIK Professor Shelley Berger and colleagues explored the genetic basis of labor distribution in communal-dwelling species and discovered that pathways dating back hundreds of millions of years are conserved across animal kingdoms. Their findings offer fundamental insights into complex social behaviors.
Shelley Berger honored by AACR for cancer research
Berger, the Daniel S. Och University Professor with appointments in the Perelman School of Medicine department of Cell & Developmental Biology and a Penn Integrates Knowledge Professor in the School of Arts & Sciences, is recognized for her outstanding contributions to cancer research by the American Association for Cancer Research with the 2025 AACR-Women in Cancer Research Charlotte Friend Lectureship.
