How do flu vaccines work?
The flu shot changes every year. But why is the flu special, if other illnesses have much longer-lasting vaccines? This episode takes us into the world of viruses and immunity.
A friendly lymphocyte fills us in on how flu shots work, and science journalist Anna Rothschild shares how vaccines started around the world. We'll hear from some virus-busting detectives to see how scientists solve the case of how to make next year’s flu shot as effective as possible. Author Maryn McKenna will stop by and drop some flu knowledge, too!

Why do we lie?
Most of us think we’re good at detecting lies, but it turns out humans only get it right about half the time. And why do we do it anyway? What makes us want to deceive other people? In this episode we get to the truth about lying. We take a look at when people start lying, and how that helps us in our development as humans. We also hear from A. Lie, who tries to remind us that we might need lies more than we think. Plus, Angela Evans stops by and fills us in on the latest lie detection research. And remember to listen for the Moment of Um at the end of the show. This time we get squishy and find out if sponges are still harvested from the sea.

What is dyslexia? And how do our brains read?
Have you heard the word dyslexia before? It's a term used to describe when people have a hard time learning to read. It's actually very common because reading is a fairly new skill that humans have developed.
In this episode we do a deep dive on dyslexia. We'll look at how our brains have cobbled together the ability to read by re-purposing parts of the brain that evolved for other functions. And we’ll learn what scientists think might be going on in the brains of people with dyslexia when they learn to read. We also talk to Ann Bancroft, a Polar explorer and educator who also has dyslexia, about why getting lost can be fun.
Plus we’ll hear a new Mystery Sound and find out if mice actually do love cheese in our Moment of Um.
