Dr. Bonnan’s research focuses on understanding the role of forelimbs, particularly in sauropods—the largest animals to ever walk the earth, in locomotion, posture, and support. Together with previous studies on lizards and other sprawling tetrapods, evidence shows that complex elbow movements are an ancient mechanism for efficient overground locomotion.

Science On Tap: Untapped returns as we celebrate 15 years of science programming! At this special edition of our science cafe, we explore the myths, legends, and science behind some of our favorite mythical creatures.

Sketching Splendor, an exhibition at the American Philosophical Society Museum, explores the work of William Bartram, Titian Ramsay Peale, and John James Audubon, three American naturalists who sought to illuminate nature’s complexity. But there were many others who also contributed to early American science, including many Native Americans, people of African descent both enslaved and free, and women whose names are less known. In this talk the exhibition’s curator, Dr. Anna Majeski, will focus on some of their stories as highlighted in the new exhibit.

For four months in 2023, community members and students worked alongside professional archaeologists to excavate artifacts and features that highlight the love, community, and humanity of the Black Bottom neighborhood and recognize the violence of its destruction under the guise of urban renewal. Co-project directors Dr. Sarah Linn and Dr. Megan Kassabaum will discuss the early stages of project planning, the 2023 excavation season, collaborative lab work undertaken in 2024, and current efforts to share the recovered stories widely.

Mark Sabaj (sa-BAY), Curator of Ichthyology, Academy of Natural Sciences. With funding from Academy benefactors Daniel and Patricia Fromm, a team of Academy naturalists (Mark Sabaj, Cecile Gama, Anwar Abdul-Qawi, Daouda Njie and David Montgomery) conducted a two-week expedition to collect fishes from the African country of Equatorial Guinea.

This talk will dive into an unexpected discipline of medicine – medical astrology - by examining some of the numerous publications on the topic housed within the Historical Medical Library of the College of Physicians of Philadelphia, many from the 14th, 15th, and 16th centuries during the height of the curious discipline's popularity.

Temple professor Becki Beadling will discuss the role of the ocean in a changing climate and how we can use both climate models and observations to improve our understanding and reduce our uncertainty in projected climate change.

This talk explores the conservation of stone sculptures and architectural materials, many of which have not been closely examined since the 1920s. We will look at the new methods and materials that have been developed for this project and reflect on how art conservation and museum practices are changing over time.

Join the Science History Institute’s curator, Elisabeth Berry Drago, and learn how the BOLD exhibition came together.

Tanya Dapkey will introduce us to eDNA and its applications, discuss what the future looks like for environmental genetics and share how scientists at the Academy of Natural Sciences are using these tools to discover biodiversity in the Delaware River Watershed. 

This talk will explore how historians and social scientists reconstruct past epidemics, beginning with the stunningly underreported “throat distemper” epidemics of New England—the greatest single mortality event among European settlers in colonial North American history. We then return to Philadelphia to consider the other Yellow Fever Epidemics of the 1790s and finish with original work conducted for the Mütter Museum’s current exhibit on the 1918 Influenza Pandemic, “Spit Spreads Death.” Combining traditional research methodologies with computational humanities technology, we can reconstruct these catastrophic events anew and recover some of the actions of those who chose not to remember or be remembered.
