Endocrine Disruptors and Drinking Water (starts at 3:12) Today we continue our series called The Ocean is Us, which explores our vital connection to the oceans. Alan Vajda, an environmental endocrinologist at the University of Colorado Denver, talks with How On Earth’s Susan Moran about a rare success story: why fish in Boulder Creek are acting and looking more sexually normal. We also explore broader water-quality issues in Colorado and beyond, and the implications for human health. For more information on studies conducted by CU and USGS scientists on endocrine disruptors related to Boulder Creek, South Platte River and elsewhere, visit BASIN. Check our website for the previous interview in the “The Ocean is Us” series, on Teens4Oceans. And check out KGNU’s year-long series on Colorado water issues. It’s called Connecting the Drops. It’s at kgnu.org and yourwatercolorado.org. To learn more or become active in preserving our watershed and the oceans, go to Colorado Ocean Coalition.

Hope On Earth (starts 7:08): Few people have thought as critically and deeply about the state of Earth and our role on it than

Baseball Vision (starts at 5:42): The major league baseball season is now in full “swing.” Fans may take it for granted that these professional athletes are in top physical condition. What’s less known is how important it is for baseball players to have perfect eyesight. Batters in particular have some of the best vision in the world. To find out how scientists know this, and study it, and even make it better, How on Earth’s Shelley Schlender last month headed down to spring training in Arizona. There, she caught up with two of the nation’s top experts on the science of vision, and sports.
Earth Day gives us plenty of reason to reflect on the state of the planet and the impact we humans have had on it. This week’s show featured 

Neuroscience of Dying (start time 12:38) If there’s one thing more certain than taxes—pardon the reminder—it’s death. It may be certain, but it’s still one of life’s biggest mysteries. On today’s show, we explore what neuroscience can tell us about chemical and hormonal releases that can occur as we near the threshold of death.

Her quest to learn whether dolphins have language, and to learn that language, is notable for its longevity. But her relationship with them is remarkably respectful, too. We last
The Ogallala Road (start time 15:15). We often hear about how the Colorado River is running dry. The Western states that rely on its flowing water are struggling to reckon with how its depleting reservoirs will satiate growing populations. You’ve probably seen images of the white “bathrub rings” at Lake Powell and Lake Mead that expose the water line rings of years ago. But there’s an equally dramatic and dangerous drop in an invisible source of water. That’s the
Amazon CO2 (start time 04:37) The Amazon basin contains the largest tropical rainforest on the planet. It’s been critical not only for its beauty and biodiversity but also for its ability to store more carbon dioxide than it emits. The soil and above-ground biomass of the Amazon makes it one of the largest reservoirs of carbon dioxide. And that has helped to keep climate change from accelerating even faster. But a new
Power Plant Smokestacks (start time 14:43) To understand the global greenhouse gas budgets, it’s critical to characterize their sources and sinks. Electrical power generation accounts for about a
