Juul Labs seemingly started out with the aim to reduce smoking, but the company's e-cigarettes came to symbolize something very different: a teen vaping epidemic.

Host Maddie Sofia talks with Time health writer Jamie Ducharme about the science and marketing behind the rise and subsequent controversy surrounding Juul Labs. Plus, a look at what might be next in the future of e-cigarettes.

Researchers report in the journal Science that they appear to have some clues about the origin of Earth's plutonium - which has been long debated. Correspondent Nell Greenfieldboyce explains that traces of rare forms of iron and plutonium have been found in extraterrestrial debris that had sunk to the bottom of the Pacific Ocean, hauled up by an oil company, then donated for research. By comparing the iron and the plutonium, scientists found the plutonium was likely forged in a cosmic cataclysm, perhaps a rare kind of supernova, and then rained down on Earth.

Eight states have passed an important milestone: getting 70% of all adults vaccinated with at least one shot. That's a number President Biden wants the country to reach by July Fourth. As cases of COVID-19 in the U.S. continue to come down, host Maddie Sofia talks with NPR health correspondent Allison Aubrey about vaccination progress around the country.

**Heads up. This episode discusses addiction and alcoholism.**

Some doctors are seeing a disturbing spike in lethal alcoholic liver disease, especially among young women. The recent trend has been supercharged, they say, in the pandemic. Emily Kwong speaks to NPR science correspondent Yuki Noguchi about this and some of the challenges to getting proper treatment.

A brain-computer interface allows a severely paralysed patient not only to move and use a robotic arm, but also to feel the sensations as the mechanical hand clasps objects . We hear from Jennifer Collinger at Pittsburgh University’s Rehab Neural Engineering Labs. And Nathan Copeland, who has been controlling the robotic arm with his thoughts via a series of brain implants.

Ralph Baric of the University of North Carolina tells us about the development of a multi-component vaccine that would be effective not just against the current coronavirus outbreak and its variants, but also future outbreaks from SARS-like coronaviruses that we don’t even know about yet.

Blood clots, thromboses, have been a problem for a small number of people following Covid vaccination Paul Knöbl, and a team of medics in Vienna have worked out the link between vaccination and clot development. They now have a method to treat such clots – so they should not be fatal.

And how did fungi and plants come to live together? Symbiotic relationships between the two are a key component of the evolution of life. Melanie Rich of the University of Toulouse has been looking at the present day genetic markers which allowed plants and fungi to help each other as they first colonised land millions of years ago.

Also...You are a star. Literally. You are a carbon-based life form and those atoms of carbon in the molecules that make up your cells were formed by a nuclear fusion reaction at the heart of long dead stars. That goes for the oxygen in your lungs too. And the red blood cells that carry that oxygen to your tissues? They contain haemoglobin, and nestled at the heart of each molecule is an element (iron) formed by a supernova - the fiery explosion at the death of a star. Your body is a walking, thinking museum of some of the most violent events in the universe.

This, as CrowdScience host Marnie Chesterton discovers, isn’t as special as it sounds. All of the stuff on the earth - the elements that make clouds and mountains and mobile phones – they all have an origin story. CrowdScience tells that story, starting with the big bang and ending with physicists, creating new elements in the lab. Find out the age of the elements and the distance they have travelled to make their current home on earth.

Solar geoengineering--the human attempt to cool the planet by reflecting sunlight away from Earth--is fraught with technological and ethical challenges. Maddie discusses some of these with contributor Ariela Zebede.

During the Great Depression, President Franklin Delano Roosevelt created the Civilian Conservation Corps to improve the country's public lands, forests, and parks. Now, nearly a hundred years later, President Biden is trying to bring a similar version of it back. He wants to launch the Civilian Climate Corps to address the threat of climate change.

NPR's White House correspondent Scott Detrow and National Desk Correspondent Nathan Rott report on Biden's plan and how it could play out.

In general, there are more men in STEMM fields than women. Representation in science, technology, engineering, math, and medicine is even lower for women of color — facing racial discrimination on top of gender discrimination. And then, the pandemic hit. Short Wave reporter Emily Kwong speaks with Dr. Eve Higginbotham about our earliest understandings of how the pandemic has impacted women in STEMM, and what support institutions can offer to make it easier for women in stay in the workforce and progress in their careers.
