"The basic premise of the event is that hunters hunt rattlesnakes from the surrounding environment all across West Texas, and bring them into the roundup for the weekend. And during the roundup, these snakes are kept in a pit and then, one by one, beheaded and skinned in front of in front of audiences." - Elizabeth MeLampy Elizabeth MeLampy is a lawyer dedicated to animal rights and protection, and her passion for this work shines through in her latest book, Forget the Camel, the Madcap World of Animal Festivals and What They Say About Being Human . To research the book, Elizabeth traveled across the country, immersing herself in a wide range of animal festivals — from the Iditarod dog sled race to the rattlesnake roundup in Sweetwater, Texas. Elizabeth examines these festivals as revealing microcosms of our broader relationship with animals. Whether it's rattlesnake hunts, frog-jumping contests, ostrich races, or groundhog celebrations, these events reflect the ways humans use animals to express cultural identity, community pride, and historical traditions. Yet beneath the pageantry and excitement lies a deeper question: Is our fascination with these spectacles worth the toll it takes on the animals involved? With compassion and insight, Elizabeth invites readers to consider whether there’s a more ethical and empathetic way to honor our stories — one that respects both animals and the traditions they inspire. Please listen, share and read, Forget the Camel. It will be released on April 8th, 2025. https://apollopublishers.com/index.php/forget-the-camel/…

Hey everyone! Today's episode is about getting into the nitty gritty of drug discovery. We often benefit from the research and development that goes into the creation of drugs we use to treat illnesses without really understanding what goes into that process. In this first part, we will discuss how you conceptually begin the process.

Last episode we discussed the current H5N1 flu that is hitting birds pretty hard. But is bird flu different from swine flu? Is there just a 'human flu', or do we only catch influenza from other animals? Let's get into the evolutionary history of the flu and primary hosts!

Sure, plants can sometimes smell good and they do cool stuff like make carbs for us to eat and oxygen for us to breathe. But they sort of look like they're just passively sitting there, right? Just chilling. If only we could hear just a slightly broader range of frequencies, we would hear a whole new world of plants -- one where they are complaining about being thirsty!

While science and medicine have come a long way over the centuries, there are still illnesses that cannot be explained -- and many of them are autoinflammatory disorders. Many people all over the world have been inflicted with these disorders with no clear cause. But recently, scientists were able to find a mutation that can help explain what some of these people are going through, a mutation that led to the identification of an autoinflammatory disorder now known as VEXAS.
