In this episode of Yackety Science, the team takes on the domesticating effects of abundant trash, and they dig deeper into ice cores, climate science, and the Mid-Pleistocene Transition. Matt continues his pun-filled rampage across the periodic table with a look at scandium. And finally, Brian scans the brain (metaphorically speaking) of Dr. Evan White to find out more about his work at the Laureate Institute for Brain Research.

Dr. Evan White

“Dr. White’s laboratory aims to establish and advance neuroscientific understanding of cultural factors that are protective against poor mental health among American Indians utilizing a strength-based framework. A focus of this research is implementing multi-modal neuroscience and psychophysiology with a particular emphasis in electroencephalography/event-related potentials. . .”

The End of Everything (Astrophysically Speaking) by Katie Mack

“. . . a mind-bending tour through five of the cosmos’s possible finales: the Big Crunch, Heat Death, the Big Rip, Vacuum Decay (the one that could happen at any moment!), and the Bounce. Guiding us through cutting-edge science and major concepts in quantum mechanics, cosmology, string theory, and much more, The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know.”

In this episode of Yackety Science, mangrove rivulus fish take a long strange trip and find their inner chill. Ribozymes lead the way back to life’s very beginning. And in the U.S., bad public policy chases away more good science. In the chemical minute, Matt mixes up a chalky mojito and talks calcium. And in Ourobookos, the team wraps up their own very strange trip through the past, present and future of TB.

Everything is Tuberculosis by John Green

“Tuberculosis has been entwined with hu­manity for millennia. Once romanticized as a malady of poets, today tuberculosis is seen as a disease of poverty that walks the trails of injustice and inequity we blazed for it. In 2019, author John Green met Henry Reider, a young tuberculosis patient at Lakka Government Hospital in Sierra Leone. John be­came fast friends with Henry, a boy with spindly legs and a big, goofy smile. In the years since that first visit to Lakka, Green has become a vocal advocate for increased access to treatment and wider awareness of the healthcare inequi­ties that allow this curable, preventable infec­tious disease to also be the deadliest, killing over a million people every year.

In Everything Is Tuberculosis, John tells Henry’s story, woven through with the scientific and social histories of how tuberculosis has shaped our world—and how our choices will shape the future of tuberculosis.”

In this episode, Brian braves the icy north winds to see half amillion cranes on the Platte River. Matt gets pig semen in his eye and comes away cancer free. Simian civil war breaks out among the chimpanzees of Uganda. And in Ourobookos, the war against TB finds both a bacterial villain and a questionable cure.
