• [BONUS] Time limits for anesthesia and stunning bioluminescence: Tiny Show and Tell Us #22

  In this episode of Tiny Show and Tell Us, we break down what limits on anesthesia could mean, both for doctors and patients. Then we hear from a listener who’s on a research trip in Puerto Rico and went kayaking in a bioluminescent bay. What is bioluminescence? And what are the perfect conditions to try to see it?We need your stories — they're what make these bonus episodes possible!

• The placenta: A disposable organ we can’t live without

  The placenta is essential for life, but so much of its function is unknown. In this episode, we talk about how this disposable organ’s development within the early weeks of pregnancy shapes so much of what happens months later. We tackle what makes the human placenta so unique, what other animals like reptiles are teaching us about it, and how scientists are turning to evolution and computer models to see if we can better understand it.Check out the IVF episode of Tiny Matters.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 glaciers safeguard Earth’s future and hold clues to our ancient past

  The reason many of us hear about glaciers has to do with sea level rise — which makes sense! If all of the glaciers on Earth melted, sea levels are predicted to increase by about 230 feet (70 meters), which would flood coastal areas, envelope a number of islands, and seriously impact human infrastructure, including our current water resources. But glaciers do more than safeguard Earth’s future — buried within them is our ancient past. In January of this year, a team of scientists drilled nearly 2 miles down into an Antarctic glacier. The 1.7 mile long cylinder of ice they pulled up, called an ice core, holds the equivalent of 1.2 million years of climate history. In this episode of Tiny Matters, we talk about what glaciers mean to us today, their importance for the future of our planet, and what they tell us about Earth’s ancient past.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] Evolutionary adaptations to high altitudes and e-cigs vs. dry herb vaporizers: Tiny Show and Tell Us #20

  In this episode of Tiny Show and Tell Us, we discuss the differences between e-cigarettes (vapes) and far-less-studied dry herb vaporizers. Then we talk about some of the incredible evolutionary adaptations of populations of people living at high altitudes. We need your stories — they're what make these bonus episodes possible!
