    AI: Safer, Smarter, More Secure (Live at AAAS)

    AI: Safer, Smarter, More Secure (Live at AAAS)

    Artificial intelligence is all around us — even if we don’t realize it. Whether it’s in a self-driving car, a food delivery app, or our nation’s electrical grid, the rapid spread of AI and machine learning raises some big questions about security. How do we make sure AI-controlled systems are working as intended? And how do we protect vulnerable technologies from outside interference? Our guests from Pacific Northwest National Laboratory are working hard to answer those questions — and to get more scientists, engineers and tech leaders to start asking them.

    The Future of Water & Wildfire (Live at AAAS)

    The Future of Water & Wildfire (Live at AAAS)

    Human health is at the top of all of our minds these days, with COVID-19 posing an unprecedented global challenge. One of the things that has a major impact on our health — and our security, the environment, agriculture, energy, transportation, you name it — is water. Water is one of our most precious resources, yet even small environmental changes can have massive consequences. In this episode, find out how the Department of Energy’s National Labs are using everything at their disposal — from supercomputers to sifting through the ashes of wildfires — to keep us one step ahead of our shifting water cycle and help us bounce back faster from natural disasters.

    Tribal Energy: Powering Self-Determination

    Tribal Energy: Powering Self-Determination

    For hundreds of Indian tribes and native communities across the United States, energy represents many things: a lifeline, a source of income, a path to sovereignty. No two tribes are alike, which is why the Department of Energy's Office of Indian Energy partners with tribal communities to develop energy projects that fit their specific needs. On this episode, learn how this small office delivers a big boost to tribes' efforts to take control of their energy destinies.
