Editing Life's Blueprint: Rewriting the Story of Us | Senumi Dharmadasa | TEDxPristinePrivateSchool
This speech offers a captivating journey through the history and future of gene editing, beginning with foundational discoveries in genetics by Darwin, Mendel, and Franklin, and culminating in the revolutionary CRISPR-Cas9 technology. It explains how CRISPR, inspired by bacterial immune systems, allows scientists to precisely edit DNA, opening doors to curing genetic diseases like sickle cell anemia and beta thalassemia. The
speaker highlights real-world breakthroughs, such as the personalized treatment of Baby KJ, and envisions a future where gene editing could eliminate inherited disorders, extend lifespans, and even resurrect extinct species. Ultimately, the speech emphasizes that while gene editing holds immense promise, it also demands thoughtful ethical consideration to ensure equitable access and responsible use. Senumi is a fourth-year medical student from Sri Lanka fueled by a growth mindset, boundless curiosity, and a spirit of spontaneity. An outgoing and adventurous lifelong learner, she is always seeking new experiences and perspectives, and constantly challenging herself. Fascinated by innovation and global health, her TEDx talk explores the powerful future of gene editing—and the responsibility that comes with it. Still finding her place in a rapidly changing world, she speaks with optimism, authenticity and a bold belief that the future of medicine must be as inclusive and dynamic as the people it serves.

- 17:23選擇的焦慮,還是探索的勇氣?|陳 惟邦|TEDx臺師大|TEDxNTNU 2025 | 陳 惟邦 | TEDxNTNU「生涯探索」是一連串對問題的回應,從當下的經驗出發,去辨認那些困惑背後未被聽見的需要。在多年的服務與陪伴經驗中,身為職涯諮詢師的陳惟邦,致力於創造一個讓學生能停下來、整理經驗線索的契機。探索不是漫無目的的漂泊,而是對自己負責的練習—在迷惘中感受,在行動中分辨,最終找出真正屬於自己的生涯道路。真正的成長不是他人告訴你該往哪裡走,是開始看懂自己已經走過什麼路。 惟邦大學期間曾於科技公司實習,擁有穩定亮眼的職涯起點,卻選擇跳脫常規,走進教育非營利組織 Teach For Taiwan,成為數位行銷工作者,參與教育現場的變革。除了專業貢獻,他更創立「職涯相談室」,結合自身行銷策略思維與對人的敏感度,陪伴來自各行各業的青年釐清自我定位、進行履歷諮詢與深度對話。惟邦關注的不只是「找工作」,而是人與職涯的長期關係。他嘗試翻轉我們對「成功選擇」的想像,鼓勵年輕世代用更有意識的方式,建構屬於自己的故事。他認為:「你內心所想那有些遙不可及的夢想,一定有機會實現。」在轉換跑道與開展服務的過程中,惟邦持續實踐作為「生涯發展的助人者」的行動。他的經歷與語言,總能讓人安心,也讓人開始想問:「我現在的選擇,是我真的想要的嗎?」我們期待透過惟邦的故事,讓對未來感到焦慮的大學生們,看見不一樣的行動線索,在壓力與混亂之中,找到屬於自己的可能起點。 This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
