Early detection of Alzheimer's disease - before symptoms are visible - may be a key to stopping the disease's progression. What warning signs are researchers looking for and what tools can they use? Paul Aisen, MD joins William Mobley, MD, PhD to discuss optimal assessments for diagnosing the disease, novel tools making earlier diagnosis possible, and the road map to developing drugs to slow, halt, and prevent Alzheimer's. Recorded on 7/29/2014.

Computer modeling is a powerful tool for scientific inquiry when experiments are too costly, too dangerous, or simply impossible. Computational physicist David Richard describes how to build a computer model of a human heart, starting from an individual cell and then using data from an actual person to create a realistic representation of a beating heart. Learn some of the tricks and techniques used to combine the power of Sequoia's 1.6 million CPUs providing examples of how doctors and researchers may soon be able to use such simulations to investigate the effects of new drugs on cardiac rhythms or improve the success rate of complex surgical procedures.

UC San Diego Computer Science and Engineering (CSE) Department Chair Rajesh Gupta, an expert in cyber-physical systems, kicks off a conversation with two cyber security experts from the computer-science faculty in UC San Diego's Jacobs School of Engineering: Prof. Stefan Savage, and Prof. Hovav Shacham. Savage and colleagues generated controversy and debate over public policy after they demonstrated the vulnerability of modern automobiles to attack from hackers who can take advantage of internal as well as external digital components and systems in today's cars. Most recently, Prof. Shacham uncovered security vulnerabilities involving the full-body backscatter, X-ray scanners deployed at entrances to airports, train stations and other public places.
