In a new format for the “Free Associations” podcast, we split our usual podcast into two bite-sized morsels. In the first segment, Jess, Matt and guest host Salma discuss an article that examines the effect of nighttime ambient light on risk of Alzheimer’s disease.

In the second segment, Jess, Matt and Salma discuss what attending a predatory conference is like and Salma explains why we should (or maybe shouldn’t) care about a rehabilitated beaver.

Matt, Jess, and guest host Salma Abdalla discuss a study of early discontinuation of oxytocin during delivery, they try to predict the future of journals alongside a mass editorial board resignation, and Matt and Salma reveal their love for octopuses.
