The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can't actually see -- like dark energy and dark matter -- and therefore don't fully understand. Theoretical physicist Chanda Prescod-Weinstein takes us inside the search for this cosmos-shaping invisible matter and explains how, with the help of a new generation of telescopes, we could be closer to demystifying it than ever before. "The universe is more queer and fantastical than it looks to the naked eye," she says. After the talk, our host Sherrell talks about the importance of inclusivity when it comes to who gets credit for technological advances. (If you want to hear more from Prescod-Weinstein, check out her episode on "The TED Interview" podcast wherever you're listening to this.)

Buildings are bad news for the climate -- but they don't have to be. While our structures are currently responsible for a third of global energy consumption and emissions, a future where they create more energy than they consume is possible. Energy policy analyst Ksenia Petrichenko has a three-tiered strategy for thinking differently about buildings, transforming them from passive users to active players in the energy system and bringing us closer to our climate targets.
