First up, host Sarah Crespi talks with Staff Writer Jon Cohen about some tricky ethical questions that may arise after the first coronavirus vaccine is authorized for use in the United States. Will people continue to participate in clinical trials of other vaccines? Will it still be OK to give participants placebo vaccines? Next, producer Meagan Cantwell talks with Bert Weckhuysen, a professor at Utrecht University, about a process for taking low-value plastic like polyethylene (often used for packaging and grocery bags) and “upcycling” it into biodegradable materials that can be used for new purposes.

First up, host Meagan Cantwell speaks with Abigail Echo-Hawk, director of the Urban Indian Health Institute and chief research officer for the Seattle Indian Health Board. Echo-Hawk shares what inspired her journey in public health and explains the repercussions of excluding native people from health data. This story was originally reported by Lizzie Wade, who profiled Echo-Hawk as part of Science’s “voices of the pandemic” series. Next, host Sarah Crespi interviews Danielle Murashige, a Ph.D. student at the University of Pennsylvania, about her Science paper that attempts to quantify how much fuel a healthy heart needs.  This week’s episode was produced with help from Podigy.

First up, Staff Writer Paul Voosen talks with host Sarah Crespi about the Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission to the asteroid Bennu. After OSIRIS-REx’s up-close surveys of the surface revealed fewer likely touchdown points than expected, its sampling mission has been rejiggered. Paul talks about the prospects for a safe sampling in mid-October and what we might learn when the craft returns to Earth in 2023. Sarah also talks with Hubert Lim, from the University of Minnesota, Twin Cities, and Neuromod Devices Limited, about his Science Translational Medicine paper on a new treatment for tinnitus. The team showed that bimodal stimulation—playing sounds in the ear and buzzes on the tongue—was able to change the brain and turn down the tinnitus in a large clinical trial.
