Sean Cummings, a freelance science writer focused on oceanographic research, discusses the remarkable Floating Instrument Platform (R/V FLIP) which can flip vertically for stability in research. He reveals plans for its renovation for future use. Meanwhile, Samantha Yousey, a bioarchaeology professor, tackles the bone paradox: do lesions indicate frailty or resilience in medieval Londoners? Their conversation delves into how ancient health indicators can reshape our understanding of human endurance and the complexities of mortality in past societies.
The FLIP research vessel, known for its unique ability to stabilize in harsh waters, has been repurposed for future ocean research and education.
Samantha Yousey's research on medieval skeletal remains reveals a complex relationship between bone lesions and individual health, challenging traditional interpretations of frailty and resilience.

The FLIP Ship Design and Functionality
The floating instrument platform, known as FLIP, is a unique ocean research platform designed to provide stability for data collection in rough waters. It can transition from a horizontal position to a vertical one, with only 17 meters above water when submerged. This design minimizes the vessel's exposure to waves, making it extremely stable even in stormy conditions, allowing researchers to conduct experiments without significant disturbances. Originally commissioned by the U.S. Navy in the 1960s, FLIP has played a crucial role in studies related to sonar and radar, where stability and minimal interference from onboard machinery are essential.
Revival of FLIP for Future Research
After being retired in 2023, FLIP was saved from deconstruction in Mexico by a company interested in creating undersea habitats. This company plans to refurbish FLIP and return it to the sea for research purposes, complementing their studies of the upper water column. The anticipated relaunch in 2026 aims to provide a stable research environment again, enabling thematic studies similar to its historical applications. As FLIP becomes available for both research projects and sea tourism, it represents a fusion of innovative ocean exploration and education.
Investigating Medieval Frailty and Resilience
Research by Samantha Yousey explores the health and longevity of individuals from medieval London through an examination of skeletal remains. The study addresses the osteological paradox, where bone lesions can either indicate poor health or resilience depending on a person's life span. Using skeletal data from various cemeteries, Yousey and colleagues developed a more nuanced index to assess frailty and resilience, considering factors like age at death and signs of trauma. The findings suggest a need for context-specific indices, enabling clearer interpretations of past populations' health based on their skeletal markers.
First up this week, a ship that flips for science. Sean Cummings, a freelance science journalist, joins host Sarah Crespi to talk about the resurrection of the Floating Instrument Platform (R/V FLIP), a research vessel built by the U.S. Navy in the 1960s and retired in 2023. FLIP is famous for turning vertically 90° so the bulk of the long ship is underwater, stabilizing it for data gathering. Additional audio from Scripps Institution of Oceanography.

Next on the show, viewing past lives using bones from medieval London cemeteries. Samantha Yaussy, a professor in the Department of Sociology and Anthropology at James Madison University, joins Sarah to talk about a bony paradox. Do lesions or scars on buried bones mean the person was frail and ill when they lived or were they strong and resilient because they survived long enough for disease to damage their bones?
