Oceanography podcasts

This episode examines whether manufacturing pharmaceuticals and biomedical materials in microgravity can become practical, with Julia Vaz and Michael Greshko. Kevin McLean speaks with Mads Peter Heide-Jørgensen about narwhals collecting oceanographic measurements that reveal Atlantic warming in East Greenland fjords. In the book segment, Angela Saini interviews Priyambada Jayakumar about her biography of agricultural scientist M. S. Swaminathan. The publisher provides a full transcript and external audio.

Nature reporters explain why record ocean temperatures associated with an intensifying El Niño could weaken marine carbon sinks. The episode also covers radiation protection for astronauts, thunder-based underground geology and experimental mitochondrial injections for vision loss.

The hosts discuss nitrogen fixation in a marine alga and the evidence for a nitrogen-fixing organelle. Related topics include plastic pollution, antimicrobial resistance and the rumen microbiome. The episode links microbial evolution and physiology with marine nutrient cycling.

Hosted by Vincent Racaniello, Michael Schmidt

This bonus crossover from Inflection Point examines carbon-capture approaches, their history and the limits of their contribution to climate mitigation. The discussion includes ocean-based approaches and the chemical processes involved. It is the publisher’s syndicated episode in the Stereo Chemistry feed, rather than a separate new recording.

Jason Rodriguez discusses piloting remotely operated vehicles on scientific expeditions, including technical problem-solving, mid-water observations and collaboration with researchers. He describes a career moving from aviation electronics through offshore work into ocean science. The full episode also includes research updates from Alan Jamieson and Thom Linley. This listing uses the full episode and its publisher-page date, rather than the separately released PRESSURISED edit.
