Farts are funny and sometimes smelly. But are they a legitimate topic of research? More than 40% of people worldwide are estimated to suffer from some kind of functional gut disorder — from acid reflux, heartburn, indigestion, constipation and irritable bowel syndrome to inflammatory bowel disease. So, yes, freelance science writer Claire Ainsworth thinks so. Claire speaks with Emily about two teams of scientists studying intestinal gases, who she profiled in a recent New Scientist article — and why understanding people's gut microbiome through a fart-shaped window may help treat these conditions at the source.

Bird flu, or avian influenza, is spreading among livestock and other mammals in the United States, raising concerns that another pandemic may be looming. Last month, California declared a state of emergency due to rising cases in dairy cattle, and there have been over 65 human cases in the U.S. during this outbreak. While cases have been largely mild and risk to the public is still considered low, scientists warn it could evolve and become more dangerous. Curious about other health updates?

Put on your headphones. In today's episode, host Emily Kwong leads us on a night hike in Patuxent River State Park in Maryland. Alongside a group of naturalists led by Serenella Linares, we'll meet a variety of species with unique survival quirks and wintertime adaptations. We'll search out lichen that change color under UV light and flip over a wet log to track a salamander keeping warm under wet leaves. Emily may even meet the bioluminescent mushrooms of her dreams. Plus, we talk about community events to get outside, such as the City Nature Challenge and Great American Campout.Do you have a question about changes in your local environment?
