Would you swallow a micro-robot? In a gutsy demo, physician Vivek Kumbhari navigates Pillbot, a wireless, disposable robot swallowed onstage by engineer Alex Luebke, modeling how this technology can swiftly provide direct visualization of internal organs. Learn more about how micro-robots could move us past the age of invasive endoscopies and op...

David Casarett asks: What if mainstream health care operated more like a medical marijuana dispensary?

Could we use the energy from light and sound to detect disease? TED Fellow Lei Li shares the exciting promise of photoacoustic imaging: an affordable, painless and accurate method of converting light into sound in order to create high-resolution images of what's going on inside our bodies. From early detection of breast cancer to steering medici...

Learn about the latest advances in the war against cancer from Stanford researcher Adam de la Zerda, who's working on some cutting-edge techniques of his own. Using a remarkable imaging technology that illuminates cancer-seeking gold particles injected into the body, de la Zerda's lab hopes to light the way for surgeons to remove even the tinies...

Viral beatboxer Tom Thum has an orchestra in his mouth, but how does he make all those sounds? Get an up-close-and-personal look as laryngeal surgeon Matthew Broadhurst sticks a camera down Thum's throat while he creates a mind-boggling array of noises. This hilarious, somewhat stomach-churning talk and performance is not for the squeamish! (Con...

Image-maker Alexander Tsiaras shares a powerful medical visualization, showing human development from conception to birth and beyond. (Some graphic images.)

TED Fellow Pratik Shah creates novel intersections between engineering, medical imaging, machine learning and medicine.

AI could propel the biggest transformation in the history of medicine, says physician-scientist Eric Topol. He explains how sophisticated AI models can interpret medical images as well or better than human experts can — and, beyond that, even pick up things that human eyes can't see. Learn all the ways AI is poised to make a difference for both ...

Is there a way to detect diseases like cancer and Alzheimer's before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can detect the spread of diseases before they can be spotted with other types of imaging. So how exactly does this wor...

How do you measure a nebula? With a brain scan. In this talk, TED Fellow Michelle Borkin shows why collaboration between doctors and astronomers can lead to surprising discoveries.

TED Fellow Lei Li is improving medical imaging that can track the progress of diseases, such as cancer, that can otherwise go undetected.

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 deve...

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 tissu...

Geneticist Steve McCarroll wants to make an atlas of all the cells in the human body so that we can understand in precise detail how specific genes work, especially in the brain. In this fascinating talk, he shares his team's progress -- including their invention of "Drop-seq," a technology that allows scientists to analyze individual cells at a...

The second deadliest day in the history of Mount Everest climbs happened in 1996 -- and Ken Kamler was the only doctor on the mountain that day. He shares the incredible story of the climbers' battle to save lives in extreme conditions, and uses brain imaging technology to map the medical miracle of one man who survived roughly 36 hours buried i...

It's an increasingly common sight in hospitals around the world: a nurse measures our height, weight, blood pressure, and attaches a glowing plastic clip to our finger. Suddenly, a digital screen reads out the oxygen level in our bloodstream. How did that happen? Sajan Saini shows how pairing light with integrated photonics is leading to new med...

Every year, tens of thousands of people have brain surgery without a single incision: there's no scalpel, no operating table, and the patient loses no blood. Instead, this procedure uses a machine that emits invisible beams of light at a precise target inside the brain. So how exactly does this treatment work? And what does it do to the tumors i...

Tech that can decode your brain activity and reveal what you're thinking and feeling is on the horizon, says legal scholar and ethicist Nita Farahany. What will it mean for our already violated sense of privacy? In a cautionary talk, Farahany warns of a society where people are arrested for merely thinking about committing a crime (like in "Mino...

Nearly 3,000 years ago, a Babylonian tablet described a curious illness called "miqtu" that caused symptoms ranging from facial twitching to full body convulsions. Today we know miqtu as seizures, and modern medicine has developed numerous treatments for those experiencing them. So what causes seizures, and is there any way to stop them from hap...

Imagine having a surgery with no knives involved. At TEDMED, Yoav Medan shares a technique that uses MRI to find trouble spots and focused ultrasound to treat such issues as brain lesions, uterine fibroids and several kinds of cancerous growths.

Why do teenagers seem so much more impulsive, so much less self-aware than grown-ups? Cognitive neuroscientist Sarah-Jayne Blakemore compares the prefrontal cortex in adolescents to that of adults, to show us how typically "teenage" behavior is caused by the growing and developing brain.

Violon, dance, singers, medical imaging, neurosciences, paleopathology, the role of the clown, education, leadership, overcoming the challenges whatever your physical or professional situation..

In a series of mind-bending demos, inventor Mary Lou Jepsen shows how we can use red light to see and potentially 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 possibly replace the MRI machine...

B. N. Horowitz, MD is a cardiologist and visiting professor at Harvard University's department of human evolutionary biology who turns to the natural world for insights into human well being.

In 2008, two 9,000-year old skeletons were found with their bones infected by an all too familiar bacterium. The ancient Greeks knew its effects as phthisis; the Incans called it chaky oncay; and today we call it tuberculosis, or TB. TB is still one of the world's most infectious killers, causing more deaths than malaria or even HIV. How has it ...
