Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3884, a red dwarf 48.5 light-years away from our solar system, in such a way that the speed of its axial spin mirrors the speed of its orbit. The result? One side of LHS 3844b is perpetually bathed in scorching sunlight, locked into a never-ending, blistering hot day, while the other is forever shrouded in darkness so cold that particles are incapable of movement, a state known as absolute zero (zero Kelvin).

A new study by researchers at the Annenberg School for Communication reveals effective ways to reduce false beliefs about nicotine.

Research from psychologists in the School of Arts & Sciences shows that children ages 3 to 5 can identify emotions in music, but that kids who show fewer signs of empathy or guilt demonstrate poorer emotion recognition. “We’re excited to continue to use music as a paradigm both to understand underlying mechanisms and as a treatment target,” Rebecca Waller says.

With their StoryMaps projects, Penn students explore the history of Philadelphia’s neighborhoods utilizing both cutting-edge tools and historical primary sources provided by the Penn Libraries.

An interdisciplinary team of researchers approaches the question ‘How do teeth mineralize?’ by analyzing the physical, biological, and genetic properties of teeth for real-world clinical applications in the future.

Online reviews can provide insight into what influences whether patients have a “good” or “bad” health care experience, a Penn Medicine analysis shows.

A new Penn Nursing Center for Health Outcomes and Policy Research study reveals a significant underrepresentation of Black nurses compared to the Black patient populations they serve, particularly in hospitals that care for a higher proportion of Black patients. The study, led Eileen T. Lake, the Edith Clemmer Steinbright Professor in Gerontology, Professor of Nursing and Sociology, and CHOPR associate cirector, is set to be published in Nursing Research.

A new study from Penn’s School of Nursing reveals a critical link between neighborhood firearm violence exposure, involvement in fighting, and adolescents’ perceived ability to obtain a firearm outside the home.

Penn Vet researchers have identified metabolic stress as an obstacle to cell transplants, highlighting a critical window for cell-based retinal repair.

A new study by a team of vision scientists from the Division of Experimental Retinal Therapies at Penn Vet, led by William A. Beltran, have worked to demonstrate that a novel surgical tool used previously in gene and cell therapy clinical trials can place therapies directly beneath the retina using a minimally invasive approach.
