  • Mission continuity plans help keep Penn operating

    Blueprints developed over 12 years are in use across campus during the pandemic.

    Penn’s senior leadership and trustees 12 years ago asked schools and centers to develop plans to guide their actions in event of a crisis to help continue operations, mitigate risk, and minimize disruption. Known as mission continuity, those blueprints are now helping to manage the impact of the pandemic.

    Penn engineers and collaborators have developed a transparent, micro-engineered device that houses a living, vascularized model of human lung cancer—a “tumor on a chip”—and show that the diabetes drug vildagliptin helps more CAR T cells break through the tumor’s defenses and attack it effectively.

    Tumor-on-a-chip offers insight into cancer-fighting cells in immunotherapy

    Penn engineers and collaborators have built a living tumor on a chip to expose how cancers block immune attacks, and how one existing drug could make immunotherapy like CAR T more effective against solid tumors.

    Can tiny ocean organisms offer the key to better climate modeling?
    Researcher Xin Sun injects substance into glass vials.

    Xin Sun prepares samples collected from the Eastern Tropical North Pacific aboard a research vessel. By adding stable isotope tracers to these vials, Sun and her team can track how different microbial groups convert nitrogen compounds into nitrous oxide, revealing how subtle shifts in oxygen and organic matter change the ocean’s chemistry.

    Can tiny ocean organisms offer the key to better climate modeling?

    In the shadowy layers of the Pacific, microbes decide how much nitrous oxide—a potent greenhouse gas—rises skyward. New research from Penn’s Xin Sun offers an improved understanding of microbial ecology and geochemistry—key to forecasting global emissions in response to natural and man-made climate change.
