Pacific lamprey have lived on Earth for about 450 million years. When humans came along, a deep relationship formed between Pacific lamprey and Native American tribes across the western United States. But in the last few decades, tribal elders noticed that pacific lamprey populations have plummeted, due in part to habitat loss and dams built along the Columbia River. So today, an introduction to Pacific lamprey: its unique biology, cultural legacy in the Pacific Northwest and the people who are

100 Years Of Box Turtles

Short Wave ·

2022/10/28

2022/10/27

When Steve Gosser heard the song of a scarlet tanager in the woods, he knew to look for a bright-red bird with black wings. But when he laid eyes on the singer, he saw instead a dark-colored head, black-and-white body, with a splash of red on its chest. "Well, that sort of looks like a first-year male rose-breasted grosbeak," he said. The song of one bird coming out of the body of another suggested this little guy could be a rare hybrid.

New Discoveries In Underwater Plant Sex

Short Wave ·

2022/10/24

Plants living underwater can't count on pollinating insects to get it on. The prevailing theory has been that pollen moves underwater simply by floating around in water currents. But a team of researchers co-led by Dr. Vivianne Solís-Weiss, have discovered a helper organism pitching in to pollinate seagrasses: marine worms. In today's episode, Vivianne tells Short Wave Scientist in Residence Regina G. Barber how she happened to catch these worms, called polychaetes, in the act of pollinating

Ever read those Choose Your Own Adventure books of the 80s and 90s? As a kid, Dr. Pamela Harris was hooked on them. Years later she realized how much those books have in common with her field: combinatorics, the branch of math concerned with counting. It, too, depends on thinking through endless, branching possibilities. She and several students set out to write a scholarly paper in the style of Choose Your Own Adventure books.
