The winter is usually when insects die or go into a state of paused development, but for tiny specks on the white snow called snow flies, it's time to run around, find a lover and make baby snow flies. Neuroscientist John Tuthill has been studying these creatures since he first came across them in 2016. He's found that not only can they survive in the cold, but if one of their limbs starts to freeze, they can self-amputate and pop it right off. That buys the snow fly time to find a mate and make sweet, sweet snow fly love.Interested in other winter biology?

In celebration of our 1000th episode, we're wrapping our heads around big numbers. Educational neuroscientist Elizabeth Toomarian talks about why humans' evolutionarily-old brains are so bad at comprehending large quantities–like the national debt and the size of the universe–and how to better equip ourselves to understand important issues like our finances and the impacts of climate change.Interested in other ways our brains make sense of the world?

Ever gotten a scarlet, hot face after drinking? Or know someone who has? Many people felt it as they ring in the New Year with champagne toasts. That's because this condition, commonly called "Asian flush" or "Asian glow," affects an estimated half a BILLION people, who can't break down aldehyde toxins that build up in their bodies. But what if there's a benefit to having Asian glow? Katie Wu, a staff writer for The Atlantic, has looked into the research a theory as to why the condition might have been a powerful tool for some of our ancestors to survive disease.
