The Fish That Inspired a Woman to Help Save a Species

A tag and release fishing trip is pictured.

Shana Miller was fresh out of college in 1998 when she came face-to-face with one of the fastest fish in the sea.

She and her friends battled for three hours to haul a 154-pound bluefin tuna aboard their boat off the Maryland coast. And when she finally looked the creature in the eye, she felt something unexpected.

“There was something very personal,” she recalled when she and I talked recently. “I felt it looking at me. It was big, beautiful, fast, and powerful. That experience put me over the edge to want to study bluefin tuna.”

I asked Miller what she did with the fish. It turns out that she and her friends ate it, not realizing then the extent of overfishing that has greatly reduced bluefin populations—to the point that western Atlantic bluefin tuna populations are now just 55 percent of their already depleted 1970 level. But I admire what happened next. Seizing on the passion that took hold that day—she describes herself as the “biggest bluefin fan on the planet”—Miller, now 38 and holder of —> Read More Here

Trick-or-Treating With Predators: Who is the Candy Bar of the Prairie?

Predators trick-or-treating across the northern plains are on the look out for their favorite full-sized candy bar. In a new video released this week, hear from our American Prairie Reserve biologists, Kyran and Damien, as they talk about the crucial role that these miniature snacks play in the larger ecosystem. Watch as hungry badgers go door to door — will they get their sweet surprise?

American Prairie Reserve (APR) is assembling a world class wildlife reserve in northern Montana, with the goal of one day creating a seamless 3.5 million acre grassland ecosystem. APR’s President Sean Gerrity is a National Geographic Fellow and was recently profiled by The Innovators Project. Learn more about the Reserve, including our work to increase prairie dog populations, on the Reserve’s website.

Ion adsorption matter in biology

Biological membranes are mainly composed of lipid bilayers. Gaining a better understanding of adsorption of solution ions onto lipid membranes helps clarify functional processes in biological cells. A new study, published in EPJ E, provides a quantitative description of the equilibria between lipid membranes and surrounding solution ions. In addition to shedding some light on biological processes, these results could also have implications for, among other things, the future development of medical diagnostics. —> Read More Here
