Immersive stories to spur action on climate
Organized by the Penn Program in Environmental Humanities (PPEH), a two-day festival, “Environmental Storytelling and Virtual Reality” begins Friday, and will explore how virtual reality and other immersive storytelling might inspire action on climate change.
Eliza Nobles, a Morris Arboretum intern, and Jessie Buckner, an ecologist with Applied Ecological Services, set up the first plots at Penn Park on a sunny morning in October. Their study will examine how using leaf mulch or allowing fallen leaves to remain on a site impacts soil health and ecology.
A second life for leaves
Taking a scientific approach to managing campus land, Facilities and Real Estate Services is partnering with soil scientists and ecologists to study how mulching plots with leaves fares for soil health and biodiversity.
An initiative of the Biomedical Postdoctoral Council Diversity Committee has established an informal network of “mentoring circles” for postdocs, graduate students, and undergraduates in STEM, with a particular emphasis on including participants from underrepresented backgrounds.
Campus orchard grows, with help from the community
Now five years old, the Penn Park Orchard is expanding, literally and figuratively. With shovels and sweat equity, members of the University contributed to those efforts at a workday.
Veterinary oncologist Karin Sorenmo and colleagues cast new light on the complex role of estrogen in canine mammary cancer. The research emerged from Penn Vet’s Shelter Canine Mammary Tumor Program, which assists in treating and then finding homes for dogs like Brownie, pictured with former oncology intern, Kiley Daube.
Estrogen’s opposing effects on mammary tumors in dogs
Estrogen’s role in canine mammary cancer is more complex than previously understood. New findings may help explain why dogs spayed at a young age are more likely to develop more aggressive cancers.
Twenty-five years after the discovery of genetic mutations that dramatically increase cancer risk, the Penn Medicine’s Basser Center for BRCA is building scientific knowledge alongside public awareness about BRCA-related cancers.
A Penn symposium will confront issues of inequitable access to a clean and safe environment and the unequal burden borne by vulnerable communities, particularly low-income and underrepresented minority populations, when it comes to environmental threats.
Ishmail Abdus-Saboor has carved out a path studying the biology of touch, pain, and itch.
The science of sensations
To confront the ills of the opioid epidemic, scientists must develop a fundamental understanding of the biology of pain. Biologist Ishmail Abdus-Saboor’s work is setting the stage for screening alternative drugs and uncovering new pathways that an opioid-alternative could target.
Chinese silver grass, Miscanthus sinensis, is a common source of biomass, burned to produce electricity or heat in power plants. Each piece is roughly 2-3 centimeters in length. (Image: Reto Gieré)
Weighing the environmental impacts of a byproduct of biofuel combustion: plant skeletons
The School of Arts and Sciences’ Reto Gieré and Ruggero Vigliaturo and colleagues found that phytoliths—small, silica-containing deposits present in many plant species—are emitted during biofuel combustion.
Genes play a role in dog breed differences in behavior
Border collies are highly trainable, greyhounds love to chase, and German shepherds make good guard dogs. While the environment plays a role, traits like these are highly heritable. A new study identifies 131 genetic variants associated with breed differences in behavior.
