Microgravity causes a ton of changes in the human body and there’s been a lot of research showing how these changes affect astronauts. One bodily function that hasn’t been studied during an active space mission? Menstruation. This episode, Dr. Samantha Yammine is joined by Manju Bangalore, an astronaut-in-training and reproductive scientist aiming to research how the human body menstruates while in microgravity.   But there’s other space news in the science world so before that, Sam explores what it will take for NASA to build a nuclear reactor on the moon. Later, she looks into how some asteroids contain the raw ingredients for DNA and RNA.   Link to Show Notes HERE  Follow Curiosity Weekly on your favorite podcast app to get smarter with Dr. Samantha Yammine — for free!

There’s a misconception that feeling deep emotions is a personality trait, rather than a neurological phenomenon. A lot of the time, it’s nature, not nurture that causes heightened emotional sensitivity. This episode, Dr. Samantha Yammine is joined by Dr. Sasha Hamdani, a board-certified psychiatrist and author of Too Sensitive: Rejection, Resilience, and the Science of Feeling Deeply. They discuss how the brain processes emotions and why some people feel their emotions more intensely than others. Sam also looks into some drama between mathematicians and OpenAI and a new study that reveals something bizarrely universal about the human race.      Link to Show Notes HERE  Follow Curiosity Weekly on your favorite podcast app to get smarter with Dr. Samantha Yammine — for free!

 It’s been 57 years since humans first landed on the moon and there are a lot of ways that space travel has evolved since then. One of the major differences is that we now support and give credit to the families supporting the astronauts behind the scenes. Here to discuss how those communities shaped the Apollo Era and how we’ve learned to better support astronaut families is sociologist Dr. Tracy Scott. Dr. Scott runs the Moonshot Era Project and is the daughter of Apollo 15 commander David Scott.   Before that, host Dr. Samantha Yammine digs into a study that reveals the first evidence of dental work among neanderthals. And later, a new paper suggests that you may be able to make up for lost sleep more efficiently than we thought.   Link to Show Notes HERE  Follow Curiosity Weekly on your favorite podcast app to get smarter with Dr. Samantha Yammine — for free!

Researching apex predators often means putting yourself in situations that are mind-boggling to the average person. Our guest, Rosie Moore, is no stranger to this. She’s found herself lost at sea researching bull sharks, waist deep the Everglades trying to find Burmese pythons, and in shark-infested waters right after an attack.   This episode, she talks to host Dr. Samantha Yammine about her research. They discuss Rosie’s experience on Shark Week, how to use forensics to analyze a shark attack, and the role of citizen science in understanding sharks.   Before that, Sam looks into a new study that alleges cats are more selfish than dogs (and people). And later, there’s evidence in a study that reveals how to keep mosquitoes from sticking around once summer ends.   If you want to learn more about sharks, be sure to check out Shark Week 2026, only on Discovery.   Link to Show Notes HERE  Follow Curiosity Weekly on your favorite podcast app to get smarter with Dr. Samantha Yammine — for free!
