But we now know that’s not true. In today’s show, we’re talking about how we can improve the state of science on women’s health, and how that begins with having a fuller understanding of the hormone shifts that occur during the menstrual cycle and...

The sex education we have in the United States today isn’t really working. And, unfortunately, it’s only set to get worse as a growing number of states are pushing to restrict what students can learn in these classes. So in today’s show, we’re going to talk about why it has been so difficult to make sex ed better and what we can actually do to change it.

Sex education is highly controversial. Last year alone, 27 US states introduced bills aimed at restricting sex ed! However, this fight over what sex ed should cover (and whether it should even be taught at all) is nothing new. We’ve been having the same fights about sex ed for over a century, and that’s a big part of the reason why modern sex education still sucks.

Why are some people straight while others are gay or bisexual? What determines our sexual orientation anyway? Today, we’re going to be diving into what we’ve learned about the biological origins of our sexuality from decades of scientific research. As you’ll see, there’s not a simple and easy story—it doesn’t boil down to something like a “gay gene.” It’s way more complex than that!

Are human beings made for monogamy or non-monogamy? This is a popular subject of debate. While some argue that humans evolved for monogamy in order to ensure parental investment in our offspring, others argue that humans evolved to be non-monogamous because it increases the odds of reproductive success and genetic diversity in our species. So which is it? That’s what we’re going to be talking about today.

    Cardiac Cowboys

    The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
