For years, we've been asking, "Which came first: the chicken or the egg?" Maybe what we should have been asking is, "Which came first: the frog or the tadpole?" A new paper in the journal Nature details the oldest known tadpole fossil. Ringing in 20 million years earlier than scientists previously had evidence of, this fossil might get us closer to an answer.

Years ago, astronomy professors started noticing something that troubled them: Many of their students didn't understand climate change and the science supporting it. So a small group of professors decided to do something about it — teach climate change in their introductory astronomy courses. Want to hear more stories about climate change?

Patrick Anderson is widely recognized as the greatest wheelchair basketball player of all time. He's represented Canada at the Paralympics six times and led his team to win three gold — and one silver — medals. But since he first started playing in the 1990s, the sport has changed dramatically. He says that's due in part to the technological innovations in wheelchair athletics. In this episode, guest host Andrew Mambo chats with Patrick about the reasons for these changes. They also cover the origin of the sport, how the innovations that have changed gameplay and the rising popularity of wheelchair basketball around the world. Plus, the commonality between sport wheelchairs and stance cars. Interested in hearing more about the science behind sports? Email us at shortwave@npr.org — we'd love to hear your feedback!

Hurricane season is heating up: Hurricane Francine hit Louisiana last week and dumped rain across the South, and forecasters expect more stormy activity in the Atlantic in the next few weeks. A big factor in this stormy weather is our extremely warm oceans. Scientists know climate change is the main culprit, but NPR climate correspondent Rebecca Hersher has been following the quest to figure out the other reasons. Hint: They may involve volcanoes and the sun. Read more of Rebecca's reporting on this topic. Questions about hurricanes or other weather disasters?

Climate change is contributing to erratic weather where cocoa beans are grown and threatening the global chocolate supply. Record rainfall last year led to fungal infections among cacao trees and dwindled supply of cocoa beans. Heat is also making it more difficult for cocoa beans to thrive. So, for day three of Climate Solutions Week, we look at one innovation in the food industry: chocolate substitutes. As big chocolate manufacturers rush to stockpile cocoa beans, some companies like Planet A Foods are looking for a more sustainable solution: an alternative that looks like chocolate, tastes like chocolate and feels like chocolate... without chocolate.

For blind and low vision adults, the ability to read braille can be life-changing. Braille literacy is directly linked to higher rates of academic success and better employment outcomes for them. But there's a problem. The U.S. is facing a national shortage of qualified braille teachers and there's a lack of scientific research around braille overall. An interdisciplinary team led by linguist Robert Englebretson wants to change that. Read some of the team's work here: - Englebretson R, Holbrook MC, Fischer-Baum S. A position paper on researching braille in the cognitive sciences: decentering the sighted norm. Applied Psycholinguistics. 2023. - Englebretson, R., Holbrook, M.C., Treiman, R. et al. The primacy of morphology in English braille spelling: an analysis of bridging contractions. Morphology. 2024. Interested in hearing more linguistics stories? Email us at shortwave@npr.org.

Some weapons used by the United States military are so powerful, they can pose a threat to the people who fire them — even in training. When weapons are fired, an invisible blast wave travels through the brains of anyone nearby. Exposure to lots of these blasts over time — even low level ones — has been shown to cause brain health problems for service members. If you liked this episode, consider checking out some more episodes on the brain, including its waste system, face blindness and the neuroscience of loneliness.

Pluto hasn't been a planet for almost 20 years. In the early 2000s, scientists discovered several objects of a similar size to Pluto. So, during the summer of 2006, members of the International Astronomical Union convened in Prague to reconsider what counts as a planet in our solar system. IAU members decided that there were three criteria to be a planet — and Pluto did meet all of them. But planetary scientist Wladymir Lyra says that even though it was downgraded to a dwarf planet, Pluto still has much to teach us about planet formation. This episode, he also lays out his case for Pluto — and many other objects in the solar system — to be considered a planet. This episode is part of Short Wave's space camp series about all the weird, wonderful things happening in the universe. Check out the full series.
