In a new study published in Science, Michael Platt, Penn Integrates Knowledge Professor and Faculty Director of the Wharton Neuroscience Initiative, shows how Hurricane Maria reshaped social behavior among rhesus macaques on Puerto Rico’s Cayo Santiago.

Alongside collaborators Professor Lauren Brent, University of Exeter, and Camille Testard, Ph.D. Candidate, University of Pennsylvania, Platt found that in the aftermath of environmental devastation, monkeys became more socially tolerant as a strategy to survive extreme heat and limited shade. The findings offer striking parallels to human resilience, showing how social connection can serve as a vital survival mechanism under climate stress.Read More

In a study published in the Proceedings of the National Academy of Sciences, Penn clinical psychologist Philip Gehrman and colleagues investigated why a sleepless night can sometimes lift symptoms of depression. Brain imaging revealed that increased activity in the amygdala and anterior cingulate cortex—two regions tied to mood and emotion—was linked to improved mood in participants, regardless of depression status. The findings shed light on the brain mechanisms behind this effect and suggest new, noninvasive paths for rapid treatment that could mimic the benefits of sleep deprivation without losing sleep.Read More

To Protect Children Online, Researchers Call for Cross-Disciplinary Collaboration
