Are you thinking of returning to school? Educator Candice Neveu shares three challenges you might face continuing your education mid-career — and three mindset shifts to speed up your learning, improve your confidence and achieve the results you want.

Competition is a core part of human nature, and it can drive us to extraordinary feats. But when it goes wrong, the results can be devastating. Poker champion and science communicator Liv Boeree introduces us to "Moloch's trap" — the dark force of game theory driving many of humanity's biggest social problems, which is now threatening to derail the AI industry.

Artist Doris Mitsch invites us to revel in the wonders of nature through her dazzling photography: stacked images of starlings in flight, hawks surfing thermal updrafts, bats echolocating through the night sky and more. Revealing the hidden trails created by creatures in flight, her work offers unique insight into the intelligence behind nature's invisible rhythms.

When it comes to technology, we're often presented with two contrasting visions of the future: one where technology fulfills all our desires, and another where it leads to chaos and conflict. Sociologist Ruha Benjamin is here with a more radical vision of the future — one where humanity isn't saved or slayed by technology, but rather uses it to uplift ordinary people and make things like health care and housing for all a reality.

Material scientist Anna Maria Coclite unveils "smart skin" — artificial skin technology that responds to touch, temperature and humidity like your very own. (It's actually even more sensitive than human skin!) From helping burn victims to paving the way to smarter, safer humanoid robots, Coclite highlights the broad-ranging potential of this innovation.

The world has plenty of clean energy. The problem is storing that energy and getting it where we need it, when we need it, says battery recycling pioneer Emma Nehrenheim. While batteries are fundamental to powering a sustainable future, their production is surprisingly harsh on the environment. She lays out the science behind a breakthrough in recycling a battery's core elements, offering a manufacturing solution that could vastly reduce the industry's environmental impact and demand for new materials from mining.

From World War I to the 2008 economic collapse and beyond, history shows that economists don't always see the future as clearly as they think they do, says economist David McWilliams. Using the words of W.B. Yeats, McWilliams makes the case for embracing unconventional thinkers – poets, artists and musicians – and offers a creative path towards a world filled with less confirmation bias and more understanding.

AI won't kill us all — but that doesn't make it trustworthy. Instead of getting distracted by future existential risks, AI ethics researcher Sasha Luccioni thinks we need to focus on the technology's current negative impacts, like emitting carbon, infringing copyrights and spreading biased information. She offers practical solutions to regulate our AI-filled future — so it's inclusive and transparent.

The current explosion of exciting commercial and open-source AI is likely to be followed, within a few years, by creepily superintelligent AI – which top researchers and experts fear could disempower or wipe out humanity. Scientist Max Tegmark describes an optimistic vision for how we can keep AI under control and ensure it's working for us, not the other way around.

Drawing on his decades-long mission to formulate the world in computational terms, Stephen Wolfram delivers a profound vision of computation and its role in the future of AI. Amid a debut of mesmerizing visuals depicting the underlying structure of the universe, he provides a sweeping survey of his life's work, offering a new perspective on the applications — and consequences — of AI powered by computational language.

US Congresswoman Lucy McBath has made it her mission to seek bipartisan solutions for gun safety, leading the way in sponsoring so-called "red flag" laws that prevent gun violence and mass shootings. In a searing and timely talk, she shares the personal story that led her to this work — and a message for why comprehensive, common-sense gun legislation in the US is more urgent than ever.

Using paychecks, perks and carefully worded mission statements plastered on posters, companies are on a never-ending quest to find what drives morale at work. An underappreciated solution lies in the answer to one simple question, says management researcher David Burkus. With notable examples backed by decades of success, he presents a clear path to inspiring your team — and finding your purpose at work.

There's a saying that comedy is tragedy plus time. Perhaps that's why some of our biggest problems feel easiest to manage with a dose of humor. Comedian, journalist and actor Roy Wood Jr. has spent his career finding the silly in the serious and using this tactic to influence real change. Listen in to learn how you can tap into the powers of humor in your own life. (This conversation, hosted by comedian Chris Duffy, was part of an exclusive TED Membership event.

When technologist Luis von Ahn was building the popular language-learning platform Duolingo, he faced a big problem: Could an app designed to teach you something ever compete with addictive platforms like Instagram and TikTok? He explains how Duolingo harnesses the psychological techniques of social media and mobile games to get you excited to learn — all while spreading access to education across the world.

Every day, people around the world spend 16 billion hours on unpaid care work — cooking for families, caring for children and older relatives and other routine household tasks — often in addition to other jobs. Employment advocate Sharmi Surianarain says we need to not only acknowledge this labor but also build supportive workplaces that put policies with care work top of mind.
