The United States is on the verge of dramatically expanding the availability of COVID-19 vaccine boosters to shore up people's immune systems. As NPR health correspondent Rob Stein reports, the Food and Drug Administration is poised to authorize the boosters of the Moderna and Johnson & Johnson vaccines. Still, many experts argue boosters aren't needed because the vaccines are working well and it would be unethical to give people in the U.S. extra shots when most of the world is still waiting for their first.

They also fight climate change by storing tons of carbon, thanks to a spectacular above-ground network of tangled roots. Ecologist Alex Moore talks to guest host Maria Godoy about how mighty this tree is, and why it is under threat.

A box of Twinkies, left alone for eight years, held some surprises for Colin Purrington. Upon having a sugar craving, combined with being "just so bored, with the pandemic," Purrington opened the box a few weeks ago. Like many people, Purrington believed Twinkies are basically immortal, although the official shelf life is 45 days. NPR's Nell Greenfieldboyce talked to Purrington and explains how two scientists got involved and started unraveling the mystery of the mummified Twinkie. (Encore episode)

The COVID-19 has exposed longstanding and massive health disparities in the U.S., resulting in people of color dying at disproportionately higher rates than other races in this country. Today on the show, guest host Maria Godoy talks with Usha Lee McFarling about her reporting — how new funding and interest has led to increased attention to the topic of disparities in health care and health outcomes, but also left out or pushed aside some researchers in the field — many of them researchers of color.

Cockroaches - do they get a bad rap? Producer Thomas Lu teams up with self-proclaimed lesbian cockroach defender Perry Beasley-Hall to convince producer/guest host Rebecca Ramirez that indeed they are under-rated. These critters could number up to 10,000 species, but only about 30 are pesky to humans and some are beautiful! And complicated! And maybe even clean.

Humans have scalp hair. But why is human scalp hair so varied? Biological anthropologist Tina Lasisi wanted to find out. And while completing her PhD at Penn State University, she developed a better system for describing hair — rooted in actual science.
To hear more from Tina, check out these webinars: Why Care About Hair (https://bit.ly/3liJZ96) and How Hair Reveals the Futility of Race Categories (https://s.si.edu/3Dik6g8). And to dive deep into Tina's research, we recommend her paper, The constraints of racialization: How classification and valuation hinder scientific research on human variation (https://bit.ly/3DfDrOS)
