A Skeletal Record Of Medieval England Society If you’ve ever fractured a bone, that skeletal trauma stays with you forever, even after it heals. So researchers across the pond are using bones from medieval times to put together a picture of what life was like. The bones in the study came from ordinary people in medieval Cambridge in the United Kingdom, from between the 10th and 14th century. The researchers found that you can often guess who was working class, and who had more money based on what their bones looked like. SciFri producer Kathleen Davis talks to Jenna Dittmar, a research fellow in osteoarchaeology at the University of Aberdeen in Scotland, about this new research. Deploying President Biden’s ‘Wartime’ COVID-19 Plan On his first day in office, President Biden released the national COVID-19 Response and Pandemic Preparedness plan. Announced on January 21, the strategy introduces a newly created advisor, the COVID-19 Response Coordinator, and the Defense Production Act, which aims to ramp up vaccine production. The goal is to administer 100 million vaccine doses in 100 days—a vaccination plan that the Biden Administration declares a “wartime effort.” Public health experts Thomas Bollyky of the Council on Foreign Relations and Amesh Adalja of Johns Hopkins University’s Center for Health Security discuss what steps will be needed to deploy the federal plan. They also look to the future and evaluate how we can better plan for pandemics, reframe our approach, and budget for public health campaigns.  Lack Of Enforcement Threatens The Endangered Species Act It’s been nearly 50 years since the Endangered Species Act passed. The 1973 legislation, designed to give government agencies tools to protect species threatened by development or other economic activity, still enjoys high amounts of public support. But, as investigative reporter Jimmy Tobias writes for The Intercept and Type Investigations this week, one of the main government agencies tasked with enforcing the Act seems to be increasingly hesitant to use its power to block development, a trend that’s stretched back at least since the Clinton administration. Tobias writes about how this lack of enforcement threatens the survival of one particular animal, the Florida panther—whose Southwest Florida habitat, and roughly 150 remaining members, are at risk from a major proposed development.  Ira talks to Tobias about the panther, the ESA, and what conservationists think needs to change.
