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.

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.
