Grand initiatives such as theNational Parks program, begun in the late 1800s, are for many people a hallmark of land conservation. However, the majority of land nationally (~60% overall; ranging from 95% on a state-by-state basis) is privately owned. These private lands can have conservation value too. Join Rangeland Manager Billy Freeman and UC Merced Management Professor Catherine Keske as they explore McKenzie Ranch, in the Sierra Nevada foothills of California to discover land conservation strategies that ensure public access and enjoyment of some of the nations otherwise hidden wonders, while also providing returns from the land to the private land owners. In a period of rapid global change, species range-shifts, and altering resource availability and risk, a diversified portfolio of lands and management practices may become increasingly important in conservation.

Globally, over the past century, coastal fisheries have faced overharvesting and mismanagement. California is no exception. This video recounts stories from fishermen, and others engaged in commercial fisheries, about the decades-long struggle to replenish stocks through a variety of management measures. Through their experiences, we discover the many successes in recovering stocks, the capricious nature of the biology of some species, and also emerging challenges for managing fisheries sustainably, including climate change, regional resources management, access, and local infrastructure. Successfully managing the complex 'bioeconomic' dynamics of coupled natural and human ecosystems, such as fisheries, will provide an ongoing challenge of paramount importance for the survival of vibrant coastal communities.

Across the tree of life, we can trace cancer vulnerabilities back to the origins of multicellularity. Cancer is observed in almost all multicellular phyla, including lineages leading to plants, fungi, and animals. However, species vary remarkably in their susceptibility to cancer. Amy Boddy (UCSB Integrated Anthropological Sciences Unit) discusses how this variation in cancer susceptibility is characterized by life history trade-offs, as cancer defense mechanisms are a major component of a body's maintenance. She also looks at how understanding these trade-offs in the context of evolution may help explain the variability we see in cancer susceptibility across human populations.

Embryos are the most complex self-assembling machines known in the universe. Joel Rothman, Professor of Molecular, Cellular, and Developmental Biology at UCSB, explores the instructions for self-assembly using a tiny animal -- the humble C. elegans worm. Find out what he has discovered and the research into life-support systems that may allow these creatures to become the first interstellar astronauts, departing the solar system at near-light speeds.

It has been a long-standing challenge to create new technologies that can match the perceptual and movement abilities of the human hand and its sense of touch in robots. Yon Visell describes the work in his lab on haptics, the science and engineering for the sense of touch, and explains how the results are guiding the development of new technologies for wearable computing, and robotics.

High school students from around the country spent part of their summer learning and living at UC San Diego. During theCOSMOSprogram, they learn from professors in the Computer Science and Engineering department. Students get to create apps, robots and lifelong memories. Some even turned bananas into a piano.

Polymers, known colloquially as plastics, abound in the world around us due to a host of useful properties. In this talk, Christopher Bates (UCSB Materials and Chemical Engineering Departments) discusses a fascinating subset of these materials known as block copolymers, which naturally self-assemble into intricate, nanometer-sized patterns. Bates' lab provides a look into the natural universe through the lens of chemistry and materials science. Series: "GRIT Talks" [Show ID: 34029]

With the vast amount of data available in digital form, the field of Artificial Intelligence (AI) is evolving rapidly. In this talk, William Wang (UCSB Computer Science) summarizes the stunning achievements of Artificial Intelligence for the past decade, especially in the subareas of Machine Learning, Natural Language Processing, and Computer Vision. He also looks at big resarch challenges ahead. Series: "GRIT Talks" [Show ID: 34034]

Teachers are learning how coding can be an exciting and useful way to teach math. San Diego Unified School District teachers spent a week of their summer at a workshop called Bootstrap with professors from UC San Diego Computer Science and Engineering. Bootstrap is a way to teach core courses, from math to social studies, using computer programming. There is even a lesson plan that lets students create their own video game. Teachers say it could be a fun new way to help their students succeed. Series: "The Computer Science Channel" [Show ID: 33846]

Drought, climate change, an aging infrastructure and growing population threaten the water Californias San Joaquin Valley uses to supply most of the nations produce and a large proportion of its livestock and dairy. "Adequate water for food for the nation is a water security issue, and its also a national security issue," says UC Merced CITRIS researcher Roger Bales in a new documentary examining water problems and solutions across the United States and globally.

Can geoengineering save the planet? Injecting particles into the atmosphere to counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis by UC Berkeley researchers. Shading the planet keeps things cooler, which helps crops grow better. But plants also need sunlight to grow, so blocking sunlight can affect growth. Series: "UC Berkeley News" [Show ID: 33999]

In October of 2018, a UC Berkeley team headed down to the Arizona desert with their newest prototype water harvester. In the backyard of a tract home it sucked water out of the air without any power other than sunlight. The successful field proved what the team had predicted; the water harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.

How it is possible for imagination to have practical social effects? The great potential size of human societies, in contrast to those of other primates, is due to a kind of shared imagination of which kinship and religion are important examples, says Maurice Bloch, Emeritus Professor of Anthropology at the London School of Economics. Bloch says that the shared imaginary emerges in normal life at certain moments yet is still governed by the potential of imagination. The lecture is illustrated by Bloch’s experience of an isolated village in Madagascar. [Show ID: 33941]

As climate change cuts into biodiversity, humans will be among the species at risk. We know this because we can already see the pattern. Berkeley ecologist and wildlife biologist Justin Brashares studies how economic and political systems affect the environment and how the changing environment in turn impacts culture.

Do you know where your water comes from? The iconic spring-fed trout waters of Mt. Shasta and High Sierra meadows are the key to California’s water future. They are a major Source of the state’s water supply, vital to its economy, its people and its fish. Yet, despite its significance, many Californians are unaware of where their water comes from and the need to protect and restore these important sources. They face a myriad of threats. From water bottling plants to hydroelectric and geothermal energy facilities in the springs to degraded meadows in the Sierra. And now – climate change. Learn more about these vital Source waters, and, how we can ensure they are productive and healthy for generations to come. Series: "Sustainable California" [Show ID: 33882]

It’s hard to comprehend large-scale change over time, says Berkeley paleontologist Charles Marshall. The rapid increase in greenhouse gas emission, soaring population growth, and resource extraction have largely occurred within one lifetime. Today, of course, human-driven change is undeniable, global and threatening. See what UC Berkeley is doing to make a difference in our future – in our climate, environment, biodiversity and energy use. Series: "Cal Future Forum: Our Changing World" [Show ID: 33076]
