Elizabeth Heller’s lab uncovers how drug addiction can create lasting changes in genes

Leading a neuroepigenetics lab at her alma mater, Heller and the work of her 10-person lab is focused on molecular brain mechanisms, aiming to uncover chronic changes that can happen and keep happening in the brain long after exposure to addictive substances ends.

Homepage image: A portrait in Leidy honors Nathan Francis Mossell, who, in 1882, became the first African American student to earn a medical degree from Penn. With its placement in the accessible portion of the building’s stairway, this new portrait gallery is highly visible to students, staff, faculty, and visitors who spend time in the Biology Department.

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.

A grooming chain of adult female rhesus macaques on Cayo Santiago, an island off the coast of Puerto Rico. Researchers in the Platt labs have studied this group of free-ranging nonhuman primates for more than a decade. This most recent work builds on previous research aimed at understanding the link between social connections and the brain. (Image: Lauren JN Brent)

Social connections influence brain structure of rhesus macaques

Researchers from Penn, Inserm, and elsewhere observed that the number of grooming partners an individual animal had predicted the size of brain areas associated with social decision-making and empathy.

Questioning what we know about dementia

Penn researchers are looking into moments of sudden, clear communication in someone with progressive neurodegenerative disease for a deeper understanding of both brain science and philosophy.

Researchers used data on soil lead content to inform their analysis of the contributing factors to lead exposure risk around Philadelphia. Many samples were collected during Academically Based Community Service courses taught at Penn. (Image: Alex Schein)

Lead toxicity risk factors in Philadelphia

Two studies identify factors that correlate with high blood-lead levels in children, pointing to ongoing environmental justice issues that disproportionately fall on children of color and poorer communities in the city.
