If you were an ant living in an anthill in the Serengeti and you wanted to know whether an intelligent species lived on planet Earth, how could you tell? A particularly clever ant might pick up a radio signal and deduce that humanity exists, but how about subtler, indirect clues that, nevertheless, are a result of technological development?

Leland Melvin’s scientific career began during his childhood in Lynchburg, Virginia, when he created a fantastic explosion in his living room with an at-home chemistry set. Little did Leland or his family know at the time that he would become both a professional athlete and a NASA astronaut, flying two missions to the International Space Station.

The wind that carved the sandstone of Arches National Park into spectacular arches and towers also plucks them, like giant guitar strings, making them ring at low frequencies. Geoscientist Riley Finnegan and her colleagues in the Geohazards research group at the University of Utah are recording these arch songs in the Park and around Utah with seismometers, the same basic technology geologists use to listen for earthquakes, to learn their characteristic vibration frequencies—and how human noise affects them.

In this episode, the second in a two-part series, we chatted with Rodrigo Salvador, Curator of Invertebrates at the Museum of New Zealand, about the connections between giant squids and the Kraken, and Danielle J. Serratos, Director/Curator of the Fundy Geological Museum, about the links between prehistoric aquatic reptiles and the Loch Ness monster, respectively.

We’ve all heard stories about fantastical creatures that people swear they’ve seen and have evidence of but can never be confirmed. Think Bigfoot or the Loch Ness monster. Mermaids or the Kraken. While there’s no evidence backing the existence of these creatures, either in present day or at any point in the past, there must be a reason why such legends were created in the first place. In most cases, the legend in grounded in fact.

The latest episode of Third Pod from the Sun features an interview with planetary scientist Fran Bagenal, who has had a fascinating career working on NASA missions from Voyager to Juno and New Horizons. Currently working at the University of Colorado Boulder, Bagenal provides an overarching view of the different planetary missions going back a few decades and describes how the research and findings have built upon the innovations and discoveries that came before.

Well-documented torrential rains and unusually cold temperatures affected the outcomes of many major battles during World War I from 1914 to 1918. Poet Mary Borden described the cold, muddy landscape of the Western Front as “the liquid grave of our armies” in her poem “The Song of the Mud” about 1916’s Battle of the Somme, during which more than one million soldiers were killed or wounded.

What happens when you cross medical science with geophysics? In one study published last year, the result was one-part interdisciplinary and one-part science fiction.

About 3,600 years ago, a colossal volcanic eruption blew apart the Greek island Thera, now the popular tourist destination known as Santorini. Falling volcanic rock and dust buried the Bronze Age settlement Akrotiri, on the south side of the island, preserving multi-story buildings, frescoes, tools, furniture and food, until archaeological excavations uncovered them in the last century, much like the eruption of Vesuvius in 79 CE famously buried Pompeii and Herculaneum. But unlike the Roman cities, Akrotiri has a notable lack of bodies.
