Buttons, Grand Canyon Maps, Mosquitoes. Feb 8, 2019, Part 2

The button is everywhere. It allows us to interact with our computers and technology, alerts us when someone is at the front door, and with a tap, can have dinner delivered to your home. But buttons also are often associated with feelings of control, panic, and fear. Rachel Plotnick, author of Power Button: A History of Pleasure, Panic, and the Politics of Pushing, discusses the development of buttons and what they reveal about our interactions with technology.

New research finds that the same pathways in the brain that control human hunger can shut down a mosquito’s interest in biting you. Rockefeller University professor Leslie Vosshall tells us about how this technique can potentially inhibit female mosquitoes from seeking out human blood—and stop the spread of disease.

Later this month, the Grand Canyon celebrates the 100th anniversary of becoming a national park. But the natural wonder has way more than 100 years of stories to tell. The millions of years of geologic history, coupled with the massive scale of the canyon, make it challenging to create a comprehensive view of the Grand Canyon. Matthew Toro, director of maps, imagery, and geospatial data for the Arizona State University Libraries, tells us about maps of the iconic park to share its geologic and cultural stories.
