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.

This week’s episode was produced with help from Podigy.
