Catching cancer at its earliest stages saves lives. But in a body made up of trillions of cells, how do you spot a small group of rogue cancer cells? Biomedical researcher Hani Goodarzi discusses his lab's discovery of a new class of RNAs that, when paired with emerging AI tools, could help detect cancer earlier, more precisely and even through routine blood work — potentially transforming our understanding of the disease.

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.

In the beginning of the universe, all was darkness — until the first organisms developed sight, which ushered in an explosion of life, learning and progress. AI pioneer Fei-Fei Li says a similar moment is about to happen for computers and robots. She shows how machines are gaining "spatial intelligence" — the ability to process visual data, make predictions and act upon those predictions — and shares how this could enable AI to interact with humans in the real world.

We're programmed to think every issue is binary: "us vs. them." But Daniel Lubetzky, the founder of KIND Snacks, says the real enemy isn't a person but a mindset. He introduces a new initiative that aims to bring together "builders" from around the world to replace extremism with practical problem-solving — and shows how you can join the movement.

Each Sunday, TED shares an episode of another podcast we think you'll love, handpicked for you… by us. Today: in celebration of Mother's Day , we're sharing an episode we think you'll enjoy from How to Be a Better Human. Activist, and MacArthur Genuis, Ai-jen Poo believes that caring for others is one of the fundamental acts that make us human. But from nannies to elder-care workers, house cleaners to living assistants, single parents and beyond, globally, caretakers do not earn fair wages or recognition for their essential, life-giving labor. The President of the National Domestic Workers Alliance, Ai-jen explains how society undervalues domestic work, and provides a framework on how we can start a conversation about the future of care for our loved ones – and ourselves.
