This week, Emily and Perry raise a glass to alcohol: the cause of, and solution to, all of life's problems. How does it actually affect our brains? How much should we, or should we not, safely be drinking? Why are studies about responsible consumption such hot, noisy garbage? And does everything al…

What's the deal with pregnancy brain? (feat. Allison Williams)
This week, Emily and Perry are joined by actress Allison Williams to discuss all things pregnancy brain. Are the fog and forgetfulness due to actual brain shrinkage?

What's the deal with cortisol?
This week, Emily and Perry take on cortisol, the much-maligned stress hormone blamed for heart attacks and stubborn belly fat. But how much heat should cortisol really be getting? How do you know when yours is too high? Too low? Is it ever really worth measuring? And you guys, what did Mendelian ra…

What's the deal with mRNA vaccines?
This week, Emily and Perry explore RNA, a tiny molecule of extraordinary potential. What is it? How is it different from DNA?

What disrupts it, and h…

What's the deal with hypoactive sexual desire disorder (HSDD)?
This week, Emily and Perry are coming in hot to discuss the existence of sex, specifically whether or not women have a DSM-5-designated disorder when they don't want it, or if that's a pathology designed to sell women meds. Turns out the data of sexual desire is a complicated and noisy thing to stu…

What's the deal with cupping and dry needling?
This week, Emily and Perry dig into dry needling and cupping, the wellness equivalent to pain equals gain (maybe?).

What's the deal with red meat?
This week, Emily and Perry pull out their steak knives to cut through both the hypers, and the detractors, of red meat. Is it as bad for you as people say? Is there value to a (fiberless) carnivore diet? What makes it red, anyway? And why is nutritional science such a heap of hot, correlation-is-no…

What's the deal with methylene blue?
This week, Emily and Perry bravely platform methylene blue, a synthetic dye with almost godlike properties according to the influencers, and some fascinating uses (and risks) in reality. Fatigued (?) mitochondria, the electron transport chain, and blue poop? AP Bio was never this fun. Plus: strawb…
