What happens behind the scenes of a dinosaur exhibit? Short Wave host Regina Barber got to find out … by taking a trip to the Carnegie Museum of Natural History in Pittsburgh. In the museum’s basement, she talked to a paleobiologist, checked out a farmland fossil find and even touched a 67 million-year-old bone. Because, as it turns out, there’s a lot of science that can be found in a museum basement.Learn more about the Carnegie Museum of Natural History’s exhibit “The Stories We Keep”.Interested in more archaeology and dino-related science?

Choose your fighter for the origin of water on Earth! Was it always here or did it come to this planet from somewhere else in space? And, either way, what does this mean for other water worlds in our galaxy? To find out, we talk with Michael Wong, an astrobiologist and planetary scientist at Carnegie Science. He gets into scientists’ strongest candidates for the ways water could have come to our planet many, many years ago – including whether it could have been made here. Buckle up: This is a hot debate in astrobiology right now.If you enjoyed this episode, check out our Space Camp series and our episode on whether life started on the ocean floor..Interested in more space science and more unresolved hypotheses about how the universe came to be how it is today?

What better time to contemplate the conundrum that is zero than the start of a new year? Zero is a fairly new concept in human history and even more recent as a number. It wasn't until around the 7th century that zero was used as a number. That's when it showed up in the records of Indian mathematicians. Since then, zero has, at times, been met with some fear — at one point the city of Florence, Italy banned the number.Today, scientists seek to understand how much humans truly comprehend zero — and why it seems to be different from other numbers. That's how we ended up talking to science writer Yasemin Saplakoglu in this encore episode about the neuroscience of this number that means nothing.Read more of Yasemin's reporting on zero for Quanta Magazine.
