NOTE: This talk contains some graphic medical imagery. Today medical scans produce thousands of images and terabytes of data for a single patient in mere seconds, but how do doctors parse this information and determine what's useful? At TEDxGöteborg,... scientific visualization expert Anders Ynnerman shows us sophisticated new tools -- like virtual autopsies -- for analyzing this myriad data, and a glimpse at some sci-fi-sounding medical technologies in development.

Jewels of the Jungle takes viewers on a world-wide quest for new natural medicines.Jewels of the Jungle takes audiences on a worldwide journey of scientific exploration, trekking throughout the forests of Australia, Bolivia and Peru, and into laborat...ories throughout the United States, presenting viewers with a first glimpse of what may become humanity’s next generation of wonder drugs.In recent years drug-resistant bacteria have rendered many of society’s ‘wonder-drugs’ impotent. And numerous diseases, including malaria and AIDS remain uncured. For Montana State University Professor Dr. Gary Strobel, the solution lays not in laboratories but in nature. Jewels of the Jungle follows Dr. Strobel as he travels throughout the world’s most remote and beautiful forests in search of new natural medicinal compounds, relying not only on Western science but also on the traditional knowledge of aboriginal peoples. And while humanity has relied on natural medicines for centuries, Strobel has found a new, revolutionary source of drugs: microscopic life forms that live inside of plants. Called endophytes, these organisms often produce powerful chemical compounds that protect their host plants from infections and diseases. It’s now become apparent that these compounds can play the same role in people. It’s also apparent that endophytes may lead to a pharmaceutical revolution, allowing for the creation of an array of more powerful, cheaper drugs that fight cancer, malaria and numerous other infections and diseases.

When someone suffers from an internal ailment that cannot be detected from a regular office exam, an MRI may be necessary. The patient lies on a platform that enters the center of the machine. Upon entering the machine, the patient is scanned by one... of several magnetic coils that administers a radio frequency pulse targeting the specific region to be examined. This creates a magnetic field that runs down the center of the tube. Learn more about Magnetic Resonance Imaging, also known as M.R.I. in this short, professionally made video. The video uses computer animation to demonstrate the MRI process as a narrator gives explanations. (01:32)
