At the dental school, the dietitian is in
Matthew Whipple, a registered dietitian at the School of Dental Medicine, consults with patients in clinics and educates students about the importance of spreading nutrition advice. He also cooks up a mean chicken and sausage gumbo.
Mutualistic interactions abound in nature, yet classical ecology models predicted they shouldn’t. With a new approach, biologists from Penn clarify what the old predictions missed. (Image: Erol Akçay)
Helpful interactions can keep societies stable
New work by Erol Akçay of the School of Arts and Sciences and Jimmy Qian, a recent alum, challenges 50-year-old predictions that mutualistic interactions make a community unstable.
In a mouse model of diabetes, a plant-grown compound helped bone fractures heal faster.
A promising new strategy to help broken bones heal faster
To improve how broken bones heal in people with diabetes, the School of Dental Medicine’s Henry Daniell, Sheri Yang, and colleagues are leading work to develop an affordable oral therapy—grown in plants.
The novel disease is serious. But risks here remain low, says Ezekiel J. Emanuel, vice provost for global initiatives, who attended a World Health Organization meeting on the subject last week.
The behavior of cats can perplex even their staunchest fans.
Demystifying feline behavior
Carlo Siracusa and James Serpell of the School of Veterinary Medicine contextualize recent findings in cat behavior science, debunk some cat-related myths, and explain why our kitties are not just “low-maintenance dogs.”
Aunifying game theory model describing the feedbacks that occur between strategic decision making and environmental change captured dynamics that occur in fisheries, in human social interactions, in soil-microbe interactions, and much more. (Image: Erol Akçay)
Illuminating interactions between decision-making and the environment
With a unifying model based in game theory, Andrew Tilman, Joshua Plotkin, and Erol Akçay of the School of Arts and Sciences inform dynamics in fields as diverse as ecology and economics.
Advancing an oral drug for pulmonary arterial hypertension
With a protein drug grown in the leaves of lettuce plants, the School of Dental Medicine’s Henry Daniell and colleagues hope to provide new treatment options for patients with pulmonary arterial hypertension, a rare but deadly disease.
Rainbow trout are the model organism of choice for immunologist Oriol Sunyer of the School of Veterinary Medicine. In a new report, Sunyer and colleagues shed light on the dual roles of a type of antibody in trout—to both defend against pathogens and sustain a healthy microbiome.

Answers to microbiome mysteries in the gills of rainbow trout
In trout, the School of Veterinary Medicine’s J. Oriol Sunyer and colleagues discovered that a particular type of primitive antibody is essential for fighting microbes that cause disease while preserving others that make up a healthy microbiome.
Milo, a 4-year-old Saint Bernard, participated in the FLASH trial. “I think that we greatly underestimate the excitement of pet owners to be involved in research and to be able to contribute to a project like this,” says Penn Vet surgeon Jennifer Huck, who is co-leading the effort with Penn Medicine’s Keith Cengel, a radiation oncologist.

Treatment in a FLASH
A clinical trial in dogs with cancer, co-led by the Perelman School of Medicine and the School of Veterinary Medicine, is testing the feasibility, safety, and effectiveness of delivering a full dose of radiation therapy in a split second.
Environmental Studies master’s student Catherine Nabukalu worked with Professor Reto Gieré to study the charcoal supply chain. She visited and interviewed workers involved with its production and trade in a number of sites in Uganda.
The many lives of charcoal
Catherine Nabukalu, an alumna of the Master in Environmental Studies program, worked with School of Arts and Sciences Professor Reto Gieré to track the charcoal supply chain through research in Nabukalu’s native Uganda.
