Fixing fat bubbles for vaccines, and preventing pain from turning chronic
On this week’s show: Lipid nanoparticles served us well as tiny taxis delivering millions of mRNA vaccines against COVID-19, but they aren’t optimized—yet, and why we might need inflammation to stop chronic pain The messenger RNA payload of the mRNA vaccines against SARS-CoV-2 is wrapped up in little fatty packets called lipid nanoparticles (LNPs). These fat bubbles were originally designed for something much different—carrying molecules into cells to silence genes. But they were useful and we were in a hurry, so not much was changed about them when they were pressed into service against COVID-19. ...

Using quantum tools to track dark matter, why rabies remains, and a book series on science and food
On this week’s show: How physicists are using quantum sensors to suss out dark matter, how rabies thwarts canine vaccination campaigns, and a kickoff for our new series with authors of books on food, land management, and nutrition science Dark matter hunters have turned to quantum sensors to find elusive subatomic particles that may exist outside physicists’ standard model. Adrian Cho, a staff writer for Science, joins host Sarah Crespi to give a tour of the latest dark matter particle candidates—and the traps that physicists are setting for them. Next, we hear from Katie Hampson, a professor in the Ins...

Reducing “COVID-19 Misinformation” While Preserving Free Speech
Misinformation about COVID-19 (such as around vaccines, masks, and ineffective drugs) has circulated widely during the pandemic, and much of this misinformation is protected by the Free Speech Clause of the First Amendment. Professor of Surgery and Perioperative Care and Professor of Law William M. Sage, MD, JD, from the University of Texas at Austin, is interviewed in this JAMA podcast.
