Thousands of languages thrive across the globe, yet modern speech technology -- with all of its benefits -- supports just over a hundred. Computational linguist Kalika Bali dreams of a day when technology acts as a bridge instead of a barrier, working passionately to build new and inclusive systems for the millions who speak low-resource languages. In this perspective-shifting talk, she outlines what happens when a language is omitted from the digital landscape -- and what can be gained when communities keep pace with the future.

When Nicolas Bourbaki applied to the American Mathematical Society in the 1950s, he was already one of the most influential mathematicians of his time. He'd published articles in international journals and his textbooks were required reading. Yet his application was firmly rejected for one simple reason: Nicolas Bourbaki did not exist. How is that possible? Pratik Aghor digs into the mystery.

Your mortal enemy has captured you and hooked you up to a bizarre experiment. He's extended your nervous system with one very long neuron to a target about 70 meters away. At some point, he's going to fire an arrow. If you can then think a thought to the target before the arrow hits it, he'll let you go. So who wins that race? Seena Mathew examines the speed of thought.

Karen DeSalvo, the chief health officer at Google, explains the partnership between big tech and public health in slowing the spread of COVID-19 -- and discusses a new contact tracing technology recently rolled out by Google and Apple that aims to ease the burden on health workers and provide scientists critical time to create a vaccine.

The fruits and vegetables we buy from the grocery story have been bred to grow bigger and faster — but at the cost of flavor and nutrition, says John C. Trimble, co-founder of Foodscaping Utah. Instead of wasting precious water to maintain the grass in our yards, he suggests we "foodscape" them instead. Not only will our produce taste better, but they'll be grown as locally as possible.

What if we could use biology to restore our balance with nature without giving up modern creature comforts? Advocating for a new kind of environmentalism, scientist and entrepreneur Emily Leproust rethinks modern sustainability at the molecular level, using synthetic biology to create green alternatives. From lab-developed insulin and disease-resistant bananas to airplanes made of super-strong spider silk, she explains how reading and writing DNA can lead to groundbreaking innovations in health, food and materials.

Microglia are the primary immune cells in the central nervous system. In the brain, they play central roles in proper development and function, as well as dysfunction and disease. In her first talk, Dr. Beth Stevens provides an overview of the many ways microglia cells operate, and how they can both harm and protect the brain. Fairly recent advances in the study of microglia through imaging have allowed researchers to identify different microglia states and study their dynamic roles at different stages of development. In her second second talk, Dr. Stevens dives deeper into the mechanisms that allow microglia to shape the network of connections between neurons in the brain. She provides an introduction to the role of microglia in synaptic pruning, the process of eliminating extra synapses in healthy developing brains. She then goes on to explain how the reactivation of this process affects aging and diseased brains.

The coronavirus pandemic is unlike anything we've ever seen in health care, says emergency physician Esther Choo. Sharing insights into how health workers are responding to the outbreak, she explains what makes this public health emergency different from others -- and provides a few simple things you can do to help. Watch to the end to hear about Choo's work deploying mobile ICUs across the United States as hospitals start to reach capacity.
