On this week’s show: Troubling signs of fraud threaten discoveries key to a reigning theory of Alzheimer’s disease, and calculating the saltiness of the ocean on one of Saturn’s moons Investigative journalist Charles Piller joins host Sarah Crespi to discuss signs of fabrication in scores of Alzheimer’s articles brought to light by a neuroscientist whistleblower. Next, researcher Wan Ying Kang talks with Sarah about Saturn’s bizarre moon Enceladus. Kang’s group wrote in Science Advances about modeling the salinity of the global ocean tucked between the moon’s icy shell and solid core. Their findings spell bad news for potential habitability on Enceladus. This week’s episode was produced with help from Podigy.
