Cooling Earth with asteroid dust, and 3 billion missing birds
On this week’s show, science journalist Josh Sokol talks about a global cooling event sparked by space dust that lead to a huge shift in animal and plant diversity 466 million years ago. (Read the related research article in Science Advances.) And I talk with Kenneth Rosenberg, an applied conservation scientist at Cornell University, about steep declines in bird abundance in the United States and Canada. His team estimates about 3 billion birds have gone missing since the 1970s. This week’s episode was edited by Podigy.

Vaping deaths - does this change what we think about public health messages
This week the Trump administration has banned the sale of flavoured vapes in the USA. The reason for that is the sudden rash of cases of pulmonary disease, including deaths, linked to vaping. The mechanism by which vaping may be causing damage to the lungs is as yet unclear, and our understanding is hampered by the heterogeneous nature of the compounds involved and the mechanisms o f delivery. David Hammond, professor in the school of public health and health systems at the University of Waterloo in Canada, is author of a recent editorial about vaping and joins us to discuss what this means for public health. Outbreak ...

Pharmacotherapy for hypertension in adults 60 years or older
One of the earliest Cochrane Reviews on high blood pressure was first published in 1998, investigating treatments for the elderly. It was substantively updated for a second time in June 2019 and we asked the lead author, Vijaya Musini, from the University of British Columbia in Vancouver Canada to tell us about the evidence.

Next-generation cellphone signals could interfere with weather forecasts, and monitoring smoke from wildfires to model nuclear winter
In recent months, telecommunications companies in the United States have purchased a new part of the spectrum for use in 5G cellphone networks. Weather forecasters are concerned that these powerful signals could swamp out weaker signals from water vapor—which are in a nearby band and important for weather prediction. Freelance science writer Gabriel Popkin joins host Sarah Crespi to talk about the possible impact of cellphone signals on weather forecasting and some suggested regulations. In other weather news this week, Sarah talks with Pengfei Yu, a professor at Jinan University in Guangzhou, China, about his group�...

Robert Anders, MD, PhD - Keeping Up With Advances in Cancer Immunotherapy and Biomarker Testing: Implications for Pathologists at the Forefront of the Emerging Precision Immuno-Oncology Era
Go online to PeerView.com/FJP860 to view the activity, download slides and practice aids, and complete the post-test to earn credit. Cancer immunotherapies are demonstrating remarkable clinical activity in an increasing number of solid tumors and hematologic malignancies. Reliable biomarkers are needed to guide clinical decisions regarding treatment selection and identification of patients who are most likely to benefit. Testing for programmed death-ligand 1 (PD-L1) expression and the presence of DNA mismatch repair deficiencies (dMMR) or high levels of microsatellite instability (MSI-H) should presently be routinely done ...
