AI As A Sidekick: Cracking Health Puzzles Together | Lingyi Xu | TEDxYouth@DoverSherbornHighSchool
Lingyi Xu shares how AI is being developed to help doctors detect lung cancer and brain diseases earlier, especially in under-resourced communities. Drawing from her own journey from business student to health-focused researcher, she explains how AI tools can act as co-pilots for physicians, turning scattered data into life-saving insight. Her talk shows how technology, when thoughtfully built, becomes a tool for equity and care in the places that need it most. Lingyi Xu is a PhD student in Computing & Data
Sciences at Boston University, where she uses artificial
intelligence to tackle real-world healthcare challenges,
like catching lung cancer early and helping researchers
understand brain diseases better. She started out in
finance coding stock models, but during the COVID-
19 pandemic, she saw firsthand how delayed diagnoses
affected real people. That experience, combined with a
growing interest in AI and health, led her to change
direction. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

- 14:14The puzzle perspective | Andrea Medina | TEDxRansomEvergladesSchoolWhat if the key to life’s toughest problems is hidden in the way you approach a simple puzzle? From childhood jigsaws to escape rooms, Andrea dives into the surprising power of puzzles to shape our minds, strengthen our relationships, and even help us see the world from a new perspective. Andrea has always enjoyed the challenge of solving puzzles, having completed over 100 escape rooms and puzzle hunts to date. As a dedicated member of her school's math team, she helped lead her team to victory at the INTEGIRLS all-female puzzle competition with her passion for problem-solving. From these experiences, she began to explore how puzzles foster collaboration and creativity, and why we can all benefit from embracing the problem-solving mindset puzzles encourage. Andrea is also a driven athlete on her school’s golf and lacrosse teams, and plays the viola in her school’s symphony orchestra. When not solving puzzles, you can find Andrea immersed in a good book or playing the guitar.

- 15:52We are giving each other for granted, and it’s drifting us apart | Mariana Serna | TEDxTES YouthToo often, we only realize the value of a moment, a person, or a relationship when it begins to slip away. We wait—for the right time or for life to teach us a lesson—only to discover that time doesn’t wait for us. The scarcity of time can become a wake-up call—not to fear, but to love more deeply and live more intentionally. Mariana is an 8th Grade TES student.

- 10:08Why social anxiety isn’t the end | Mariana Bento | TEDxTES YouthLiving with anxiety doesn’t mean living without hope. What we often call “shy” or “quiet” can be something deeper—something that shapes not only our actions, but our sense of self. But what if anxiety isn’t a flaw to fix, but a part of being human to understand? With the right tools, a bit of compassion, and the courage to show up anyway, even the most overwhelming moments can become manageable. And maybe, they can lead us somewhere stronger.

- 12:00No estoy sola, y tú tampoco | Maria Paula Rodriguez | TEDxTES Youth¿Y si el miedo no fuera un enemigo, sino una señal de que necesitamos cuidado? Nos enseñaron a ocultarlo, a callarlo, a resistir… como si sentir fuera una debilidad. Pedir ayuda no es rendirse, es un acto de valentía. Aceptar nuestras emociones no nos rompe, nos revela. Porque ser fuerte no es cargarlo todo en silencio, sino reconocer que no tenemos que hacerlo solos. Maria Paula is a psychologist.
