Led by School of Arts & Sciences prof Brian Gregory and postdoc Xiang Yu, researchers have uncovered one way plants respond to hormonal cues. A similar process is likely at play in mammals.
The School of Dental Medicine is enhancing and integrating its digital capabilities, opening up new possibilities for training students, conducting research, and delivering seamless and cutting-edge patient care.
Customized kits turn students’ dining rooms into biology labs
Students in introductory biology laboratory courses in the School of Arts & Sciences used customized laboratory kits to get hands-on practice with the scientific method.
A tiny virus has transformed life as we know it. But in nearly every corner of Penn’s campus, researchers are making remarkable progress to combat it.

Uniting against an invisible foe
All across the University, researchers have launched new areas of study, reaching across disciplinary boundaries to make stunning progress in combating COVID-19.
Five things to know about the promising COVID-19 vaccine news
Drew Weissman of the Perelman School of Medicine, whose work is a key factor helping to enable two vaccines in late stages of testing, sheds light on the biology behind them and on his predictions about next steps in vaccine development and approval.
Samples of nasal polyps removed from patients with chronic rhinosinusitis revealed the perforin-2 protein (labeled in green) in the cellular plasma membrane. A pore protein, perforin-2 may be how IL-33, a key immune signaling molecule, is able to exit these cells to trigger an immune response, according to new work led by a Penn Vet-led team.

Parasitic worms offer ‘the missing link’ on the dual nature of a key immune regulator
Whether the signaling molecule IL-33 wakes up or turns down the immune response depends on what cell type releases it, School of Veterinary Medicine researchers found.
When facing the challenges of the current moment, Penn students, faculty, and staff have options to promote their emotional, mental, and physical well-being.
An international team, co-led by the School of Dental Medicine’s George Hajishengallis, showed how immune “training” transforms certain immune cells to target tumors.
According to research by the School of Dental Medicine’s George Hajishengallis and colleagues, novel insights into a pathway that restrains the immune response opens up new avenues for treating inflammatory and autoimmune conditions.
