Fungus and Wildfire Smoke: The Hidden Dangers
Wildfire smoke can transport harmful fungi, such as valley fever, over long distances, potentially causing respiratory issues. Fungi have the ability to adapt to higher temperatures, making them a concern in a warming climate. Some fungi can be resistant to antibiotics and difficult to treat due to their close genetic relationship to humans. Wildfires can exacerbate the spread of fungal infections, as seen with the recent increase in hospital admissions for valley fever after smoke exposure. Although a fungal pandemic like in 'The Last of Us' is unlikely, researchers are uncovering more about the adaptability and potential dangers associated with fungi.
Lucy - Our Ancient Ancestor Who Walked Upright
Lucy, an Australopithecus afarensis specimen, demonstrates the ability to walk upright like modern humans. Research using muscle modeling suggests that Lucy was proficient at bipedalism and had strong legs, with her thighs and calves being over twice the size of those in modern humans. The distinction between bipedalism and walking upright is significant in understanding human evolution. Lucy's discovery in 1974 provided evidence of early bipedalism around 3 million years ago, challenging previous conceptions. This finding sheds light on the complex evolution of humankind's unique qualities and challenges the idea of human exceptionalism.
The Curious Qualities of Fungi
Fungi possess intriguing qualities and adaptations that make them distinct and fascinating. Fungi have a close genetic relationship to humans and can be difficult to treat with medications that may harm the host. Some species, like Candida auris, have developed heat tolerance and the ability to infect healthy individuals. While some fungi form symbiotic relationships with humans, others, like valley fever, can cause respiratory issues, and their spores can be transported by wildfire smoke. Climate change could impact the spread of fungi, posing potential challenges for human health.
Guest host Kasha Patel talks how wildfires could play a part in spreading Last of Us-like fungi, Rachel spins a yarn about how bananas can induce crippling fear, and Sara Kiley describes our buffest, beefiest ancestor ever.
