How Is Your City Tackling the Climate Crisis? “If we can unlock the full potential of our cities, we can minimize the price the planet pays for hosting us in our growing numbers,” says Marvin Rees, the Mayor of Bristol, UK, who understands deeply how cities can help (or hurt) the environment. Rees notes that while sustainable infrastructure already exists in many parts of the world — like electric buses in Colombia and freshwater reserves in Singapore — major investments could make similar innovations more far-reaching and successful. He highlights the pivotal role of city mayors in advocating for a “worldwide network of efficient decarbonized cities” that will bring the world closer to its climate goals.

How We’re Reverse Engineering the Human Brain in the Lab. Neuroscientist Sergiu P. Pasca has made it his life’s work to understand how the human brain builds itself — and what makes it susceptible to disease. In a mind-blowing talk laden with breakthrough science, he shows how his team figured out how to grow “organoids” and what they call brain “assembloids” — self-organizing clumps of neural tissue derived from stem cells that have shown the ability to form circuits — and explains how these miniature parts of the nervous system are bringing us closer to demystifying the brain.

A Case For Color Blindness. Racial inequality provokes passionate opinions and varied ideas of how to build a fair, equitable society. One topic that’s been contentiously debated for generations is color blindness: the concept that we should look beyond race when thinking about equity. In this talk, writer and podcast host Coleman Hughes makes a case in favor of the idea, sharing why he thinks the key to reducing inequality and easing racial tensions is replacing race-based policies with class-based ones.

The Beauty Of Building With Mud And Trash. What if we could use waste to create resilient and sustainable buildings? Bringing out the beauty of the dirt beneath our feet, climate-responsive architect Vinu Daniel shares how he and his team are giving local and discarded materials (think: mud, plastic and used tires) a second life by using them to create dreamlike homes, schools and other public spaces.

Why I Built My Own Time Machine. Experiential artist Lucas Rizzotto was going through a tough breakup, so he did what anyone would do: he built a personal time machine. In a playful talk, he shares how his free-ranging experimentation led to various delightful, unexpected innovations that are changing how people think about the relationship between technology and art. “Technology gives us the tools, but art shows us the way,” he says.

The Problem With Plastics And How They’re Changing The Environment. Plastics are everywhere — they’re in our favorite electronic devices, they package our food and insulate our homes. Today, the total mass of plastic is twice the total mass of all living organisms on the planet, and it’s starting to change the processes that allow the Earth’s climate system to work. Plastic pollution researcher Patricia Villarrubia-Gómez breaks down the consequences of producing all of this plastic at every stage, from fossil fuel extraction to the disposal of single-use plastics in landfills and oceans. The first step to breaking free of our plastic problem is admitting we have one.

The Joy Of Learning Random Things On Wikipedia. Writer Annie Rauwerda makes a habit of getting lost among the seemingly endless digital archives of Wikipedia, discovering fake towns, promiscuous tortoises, 19th-century fangirls and so much more. An avid editor of the crowd-sourced platform, she speaks to the joys of exploring niche and humorous subjects, accidentally learning just for fun — and broadening your horizons along the way.

The Power of Vulnerability. Brené Brown studies human connection — our ability to empathize, belong, love. In a poignant, funny talk, she shares a deep insight from her research, one that sent her on a personal quest to know herself as well as to understand humanity. A talk to share.

What You Can Learn from People Who Disagree With You. Youth leader Shreya Joshi diagnoses a key source of political polarization in the US and shows why having “uncomfortable conversations” with people you disagree with is crucial to bridging the divide. “When we are able to recognize what unites us, it becomes so much easier to have conversations about what divides us,” she says.
