Malls are designed to overwhelm our brains. Add the stress of holiday shopping, and a quick trip to pick up presents could turn into an hours-long shopping spree thanks to all the ways stores use research from fields like consumer neuroscience and neuromarketing to entice you. Retailers create urgency and scarcity to push you to give into the emotional part of your brain, motivated by the release of dopamine. But we've got your back! With the help of NPR business correspondent Alina Selyukh, we get into the psychology of sales and discounts: Why it's SO hard to resist the tricks stores use — and some tips to outsmart them.

This encore episode, Jessica Mejía, a postdoctoral researcher in glaciology at the University of Buffalo, explains what it's like to live on a glacier for a month and what her research could mean for coastal communities all over the world.Curious about other research happening around the globe?
