The first of two lectures on weed identification techniques and some methods of control. Here, Tom Lanini, UC Cooperative Extension Weed Ecologist, makes his presentation to UC Master Gardener students about various weed control methods. Topics include cultivation, the use of animals like geese and sheep, irrigation, mulch, and organic herbicides. Presented as part of the UC Master Gardener Lecture Series.

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.

Our bodies are made up of trillions of different types of cells that carry out specific life processes. The way that these cells function is defined by the microscopic complexes contained within, which are smaller than the wavelength of light. Often times, dysfunction of these tiny cellular complexes lead to diseases, such as cancers and neurodegeneration. In this presentation, The Scripps Reasearch Institutes' Gabriel Lander takes you on an exploration of the field of "structural biology", and the use of an important tool that allows us to image the impossibly small nanomachines in our cells, in order to find out how they work and interact with each other.

Each year millions of people go to the doctor because of dizziness. Dr. Kimberley Bell, DPT hosts a panel of experienced clinicians to explore the multi-factorial causes of dizziness and vertigo, and offer strategies and tips to find relief. The neurological and vestibular causes of dizziness and vertigo are discussed.

Michelle Dougherty, co-director of Sonic Sea, discusses this new film that traces the connections between increased man-made ocean noise and fatal stress on ocean life. Michael Hanrahan, an educator and filmmaker who teaches environmental media storytelling at the University of California, Santa Barbara, moderates. Recorded on 07/28/2016.

Mobile devices are an integral part of our daily lives. But with their growing functionality and capability comes increased risk to personal privacy and security. At a fundamental level, mobile devices are incredibly hard to secure. Ben Zhao, Professor of Computer Science at UC Santa Barbara, discusses some of the fundamental security and privacy risks in mobile device and recent work in identifying and addressing the problem of "Sybil Devices," software code that pass themselves as mobile devices to manipulate and attack mobile apps from within. Recorded on 07/12/2016.

Self-driving and autonomous automobiles present new challenges that are not only technical, but also of a broader social, legal, and even ethical nature. Such issues will become more urgent and important as collisions and accidents involving self-driving or semi-autonomous vehicles occur more often harming, injuring or even killing humans in the real world. Mohan Trivedi, Distinguished Professor of Electrical and Computer Engineering, founding director of the Computer Vision and Robotics Research Laboratory, as well as the Laboratory for Intelligent and Safe Automobiles (LISA) at the University of California San Diego, discusses these challenges from the perspective of a researcher. Recorded on 05/03/2017.

The Rady School of Management at UC San Diego presents J. Craig Venter, the Co-Founder and Executive Chairman of Human Longevity Inc. as the keynote speaker for its 2017 Michael Kriegler Memorial Lecture. Venter describes in fascinating detail how researchers saved his life by diagnosing his own prostate cancer using new imaging techniques that caught what routine biopsies had missed. Venter shares other stories of breakthroughs that demonstrate how genomics-based technology is transforming the practice of medicine. Venter is introduced by Ashley Van Zeeland, a Rady alumna with significant experience leading innovative scientific programs, including groundbreaking work in the genetics of autism, neurodevelopmental disorders and other rare genetic pediatric diseases.

Revolutionary changes to materials and structures are now possible with 3D printing, bringing concepts that were previously only imagined into reality. This breakthrough technology fabricates components by adding material layer by layer from the bottom up allowing for the creation of highly complex and previously unrealizable structures.

Rosina Bierbaum, formerly of President Obama's Council of Advisors on Science and Technology (PCAST) and an Adaptation Fellow at the World Bank shows how climate change will affect all regions and sectors of the economy, and disproportionately affect the poorest people on the planet. Therefore, improving the resilience, adaptation, and preparedness of communities must be a high priority, equal to that of achieving deep greenhouse gas reductions,and rapid development and deployment of innovative technologies, as well as altered planning and management strategies, will be needed in the coming decades to achieve a sustainable world. Recorded on 05/08/2017.

With the US's commitment to the Paris Agreement in question and the future of federal climate change policy unclear, what steps should California take to remain at the forefront of climate action policy? UC Berkeley's Meredith Fowlie, Sol Hsiang, and Carol Zabin join in a discussion moderated by Center for Environmental Public Policy Executive Director Ned Helme about California's policy options given potential conflicts with the Trump administration on issues of climate change and the environment. This presentation was part of Cal Day 2017, sponsored by the Goldman School of Public Policy at UC Berkeley. Recorded on 04/22/2017.

The human mind is one of the features that makes our species unusual, and any narrative of our origins must include explanations for how our mental facilities were generated by genetic and cultural evolutionary processes. Comparative studies with the minds of other species and direct studies of how the typical human brain creates the mind are valuable approaches. However, many useful clues can also be gleaned from studying extraordinary variations of the human mind. This Symposium brings together experts who have pursued in-depth explorations of some of these variations. Recorded on 05/05/2017.
