With plants as a model, studying the ‘complexity and reproducibility’ of developmental biology

In his first year at Penn, biologist Aman Husbands is busy working on projects to illuminate the molecular mechanisms that govern plant development.

The changing face of portraiture at Penn

Efforts around campus aim to diversify those honored in portraits and rethink how to approach representation through art.

Rapid adaptation in fruit flies

New findings from School of Arts & Sciences biologists show that evolution—normally considered to be a gradual process—can occur in a matter of weeks in fruit flies in response to natural environmental change.

Context-dependent behavior can make cooperation flourish

Recent studies led by School of Arts & Sciences’ researchers show that changing social strategies between settings—for example, cooperating at home but not at work—can in fact lead to more cooperative behavior in a society.

From corals to humans, a shared trigger for sperm to get in motion

Coral sperm require a specific pH to move, according to research from the School of Arts & Sciences, which identifies a signaling pathway that is shared by organisms including humans. The results inform how corals may fare with climate change.
