Pandemic preparedness, three years early
Students work at a table covered with paper, water bottles and markers.

Participants in the first PennDemic, which took place in 2018, lay out a timeline of the “outbreak.” Two additional simulations have since taken place, with one more scheduled for this coming fall.

    • Pandemic preparedness, three years early

    In a Q&A, team members behind the outbreak simulation PennDemic discuss how the exercise, now in its fourth iteration, equipped an interdisciplinary group of grad students for COVID-19 and beyond.

    Protein’s ‘silent code’ affects how cells move

    A School of Veterinary Medicine-led study shows how, despite having nearly identical amino acid sequences, two forms of the protein actin differ in function due their distinct nucleotide sequences.

    A naturally occurring canine disease called granulomatous meningoencephalomyelitis replicates many features of multiple sclerosis, including the involvement of B cells (in red) and T cells (green) in the tissues that line the central nervous system. (Image: Penn Vet)

    With remarkable similarities to MS, a disease in dogs opens new avenues for study

    Researchers at the School of Veterinary Medicine led by Jorge Iván Alvarez and Molly Church found that the canine disease granulomatous meningoencephalomyelitis shares many of the same pathological and immunological features as MS.

    Aja Carter and colleagues found that amphibian vertebrae acquired modifications as their habitat shifted from water to land and back. (Pre-pandemic photo)

    For early amphibians, a new lifestyle meant a new spine

    Moving from water to land and back again corresponded with distinct changes in animals’ spinal morphology, according to a new study led by paleontologist Aja Carter.

    Newly described horned dinosaur from New Mexico was the earliest of its kind

    With a frilled head and beaked face, Menefeeceratops sealeyi lived 82 million years ago, predating its relative, Triceratops. Researchers including Peter Dodson, of the School of Veterinary Medicine, and Steven Jasinski, who recently earned his doctorate from the School of Arts & Sciences, describe the find.
