Neighborhood Science at Twin Oaks Branch Library
Science Under the Stars has expanded to include the Austin Public Library! At Neighborhood Science, previous SUTS speakers will present at different library branches around the city a couple times a month. Below are the dates and descriptions for this fall at the Twin Oaks Branch Library, 1800 S 5th St, Austin, TX 78704. All talks begin at 7pm.

The Amazon rainforest is home to two unexpected titans. Leafcutter ants are peaceful, sedentary farmers responsible for processing huge volumes of tropical vegetation. They use their foraging material to cultivate obligate, fungal nurseries that cradle precious brood deep within their subterranean fortresses. Few organisms are courageous or capable enough to threaten mature leafcutter colonies, but the tank army ant is one of them. Tank army ants are nomadic, subterranean ant-killing machines. Their colonies can reach as many as several million and their hunger for leafcutters is insatiable. They flush out and overwhelm kilograms of prey every day with their numbers, mandibles, and venomous stings. And yet, leafcutter nests are not without defenses. Leafcutter colonies rapidly mount impressive responses to the alarming presence of tank army ant scouts including specialized soldiers, construction of barricades, and air-tight linear battlefronts. These two large, complex, derived societies clash in epic battles akin to the wars waged long ago by the Greeks and Romans with heroes just as notable as Hercules and Achilles. Such examples of social conflict are of great interest to systems science and parallels can be drawn to instances of immune systems vs disease, competing economies, and even human warfare. Join me for a night of bravery, sacrifice, and storytelling as I share my passion and knowledge about this riveting rivalry!

Should that be Thursday, October 3?
Good catch! You are right. I have corrected that now. Thank you!
