Every month, 1.8 billion people menstruate globally. For those people, managing periods is essential for strong reproductive and emotional health, social wellbeing and bodily autonomy. But a lot of people haven't been educated about periods or the menstrual cycle since they were kids — if at all.
This episode, a period manual in four parts: How periods work, the different stages of the menstrual cycle, how to know when something's wrong, and whether to have a period in the first place.

Speaking to Short Wave from about 250 miles above the Earth, Josh Cassada outlined his typical day at work: "Today, I actually started out by taking my own blood," he said. The astronauts aboard the International Space Station are themselves research subjects, as well as conductors of all sorts of science experiments: Gardening in microgravity, trapping frigid atoms, examining neutron stars. Then, there's the joy of walks into the yawning void of space. Speaking from orbit, Cassada told fellow physicist and Short Wave Scientist in Residence Regina G. Barber about research aboard the station, what it takes to keep the ISS going and which countries' astronauts make the best food.

Time is woven into our personal memories. If you recall a childhood fall from a bike, your brain replays the entire episode in excruciating detail: The glimpse of wet leaves on the road ahead, that moment of weightless dread and then the painful impact. This exact sequence has been embedded into your memory thanks to some special neurons known as time cells. Science correspondent Jon Hamilton talks to Emily about these cells — and why the label "time" cells is kind of a misnomer.

In 1967, Jocelyn Bell Burnell made a discovery that revolutionized astronomy. She detected the radio signals emitted by certain dying stars called pulsars. Today, Jocelyn's story. Scientist-in-residence Regina G. Barber talks to Jocelyn about her winding career, her discovery and how pulsars continue to push the field of astronomy today. (encore)

Being small has its advantages - and some limitations. One organism that intimately knows the pros and cons of being mini is the pumpkin toadlet.
As an adult, the animal reaches merely the size of a chickpea. At that scale, the frog's inner ear is so small, it's not fully functional. That means the frog's movements seem haphazard. Today, with the help of Atlantic science writer Katie Wu, we investigate: If a frog can't jump well, is it still a frog? (encore)
Read Katie Wu's piece in The Atlantic, A Frog So Small, It Could Not Frog.
