• [BONUS] Fetuses ‘listening’ to different languages and climate change affecting psychiatric meds: Tiny Show and Tell Us #26

  In this episode of Tiny Show and Tell Us, we talk about how climate change may impact the effectiveness of mental health medications and how heat waves impact mental health more generally. Then we cover how fetal heart rates can change depending on which language they’re hearing while in the womb. We need your stories — they're what make these bonus episodes possible!

• How NASA scientists are monitoring and predicting wildfires from space

  Climate change has brought forth extreme fire events, like the Palisade and Eaton fires in Los Angeles, which devastated communities in Altadena and the Pacific Palisades in the beginning of 2025. And it’s becoming harder to not wonder: Is this just the world we live in now? Under the constant threat of catastrophic fires? Fortunately, we have the perfect guests to answer that question. We traveled to NASA’s Goddard Space Flight Center and spoke with two of their scientists who study fires from space.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

• How a Mars mission from the 1970s shaped the search for extraterrestrial life today

  In 1975, NASA launched two spacecraft to Mars. Viking 1 and Viking 2 arrived at their destination less than a year later, each bringing a lander to explore the surface of the planet and an orbiter to survey above. What was supposed to be a 90 day mission ended up lasting until the early 1980s. Those years provided scientists with important data about the Martian landscape, from seismometer readings of marsquakes to the reddish color of the sky.But the Viking missions had another important task: they were going to look for possible signs of life. The Viking experiments would go on to become an important landmark in science, one that’s helped researchers in a number of fields figure out what we can be doing better to find signs of life beyond Earth.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

• [BONUS] Babies leaving cells behind in mom and rethinking the Big Bang: Tiny Show and Tell Us #24

  In this episode of Tiny Show and Tell Us, we talk about what dark energy and dark matter are made out of and how knowing more could upend our understanding of the Big Bang. Then we cover microchimeric cells — cells transferred between baby and mom — and how new research in mice shows that fetal cells that took residency in mom from a first pregnancy are replaced by new fetal cells of a second pregnancy.We need your stories — they're what make these bonus episodes possible!
