How cancer cells communicate — and how we can slow them down | Hasini Jayatilaka

When cancer cells are closely packed together in a tumor, they’re able to communicate with each other and coordinate their movement throughout the body. What if we could interrupt this process? In this accessible talk about cutting-edge science, Hasini Jayatilaka shares her work on an innovative method to stop cancer cells from communicating — and halt their fatal ability to spread.

In a series of mind-bending demos, inventor Mary Lou Jepsen shows how we can use red light to see and stimulate what’s inside our bodies and brains. Taking us to the edge of optical physics, Jepsen unveils new technologies that utilize light and sound to track tumors, measure neural activity and could eventually replace the MRI machine with a cheaper, more efficient and wearable system.

How AI is making it easier to diagnose disease | Pratik Shah

Today’s AI algorithms require tens of thousands of expensive medical images to detect a patient’s disease. What if we could drastically reduce the amount of data needed to train an AI, making diagnoses low-cost and more effective? TED Fellow Pratik Shah is working on a clever system to do just that. Using an unorthodox AI approach, Shah has developed a technology that requires as few as 50 images to develop a working algorithm — and can even use photos taken on doctors’ cell phones to provide a diagnosis. Learn more about how this new way to analyze medical information could lead to earlier detection of life-threatening illnesses and bring AI-assisted diagnosis to more health care settings worldwide.
