Here's a conundrum: the same aerosol pollutants that harm human health also help cool the climate, says atmospheric scientist Sarah J. Doherty. Is there a way to clean up the air without warming the planet? Exploring the unintended consequences of reducing air pollution, she makes the case for a better understanding of marine cloud brightening — or intentionally adding sea salt aerosols to clouds over the ocean, which could reflect sunlight back into space and potentially reduce global warming.

In an exclusive preview of unreleased technology, designer and inventor Jason Rugolo unveils an entirely new kind of computer you can talk to like a friend.

The electoral system in the United States needs a redesign, says political reformer Andrew Yang. Exposing the flaws of a system built on poor incentives, he proposes a cost-effective overhaul inspired by primary elections already working in places like Alaska and advocates for ranked-choice voting, where voters can choose candidates in order of preference regardless of party, stemming the influence of extreme ideologies.

How much should we invest in teachers, and what should new investment actually involve? Education innovator Randy Seriguchi Jr. suggests the US should create a "G.I. Bill" for teachers, with a particular emphasis on uplifting Black male professionals. He shares a model of this idea in action through community partnerships in San Francisco, which provide aspiring teachers with graduate school tuition, subsidized housing, personalized fit assessments and more. "If we truly want to elevate this profession to inspire new, diverse talent to join us, we have to improve both the personal and professional experiences associated with teaching," says Seriguchi.

Marrying for love is a relatively recent phenomenon for humanity, and we still don't fully understand what it means for building successful relationships, says author and psychiatrist George Blair-West. Drawing from his extensive experience working with couples, he shares four questions every couple should ask themselves before tying the knot — and highlights surprising findings on how the way marriage starts impacts if it ends.

In a scorching talk, marketing professor and podcaster Scott Galloway dissects the data showing that, by many measures, young people in the US are worse off financially than ever before. He unpacks the root causes and effects of this "great intergenerational theft," asking why we let it continue and showing how we could make it end. (Note: This talk contains mature language.)

No one truly understands AI, not even experts, says Helen Toner, an AI policy researcher and former board member of OpenAI. But that doesn't mean we can't govern it. She shows how we can make smart policies to regulate this technology even as we struggle to predict where it's headed — and why the right actions, right now, can shape the future we want.

As climate change leads to more and more natural disasters, a group of workers is showing up at one site after another to rebuild and repair. Labor organizer Saket Soni tells the stories of Resilience Force — the group of mostly immigrant workers restoring homes after hurricanes, floods and fires — and describes the unexpected bonds developing between the residents whose lives have been turned upside down and the laborers helping put things back together.
