In hot water: Coral resilience in the face of climate change

Over a decade, researchers from Penn studied coral species in Hawaii to better understand their adaptability to the effects of climate change.
More than skin deep: A molecular and mechanistic look at pigmentation variation

PIK Professor Sarah Tishkoff led a collaborative team of researchers who have discovered key insights into the molecular basis of skin color differences among Africans. “There’s so much genetic diversity in African populations, but they’ve also been historically underrepresented in studies,” Tishkoff says. “Our findings offer more information on these populations and paint a clearer picture of human evolution.”

Research shows how stress activates neurons that disrupt sleep

New research from Penn Medicine shows suppressing these neurons may be a promising target for therapies to treat stress-related sleep disorders, like insomnia and PTSD.
