Researchers deployed a fleet of 100 semi-autonomous vehicles to test whether a new AI-powered cruise control system can help smooth the flow of traffic and improve fuel economy.

In a massive traffic experiment, scientists tested whether introducing just a few AI-equipped vehicles to the road can help ease “phantom” jams caused by human behavior and reduce fuel consumption for everyone.

UC Berkeley drills a 400-foot borehole to explore geothermal heating on campus.

UC Berkeley plans to decommission its 40-year-old cogeneration plant and replace its current steam heating system with a new system that uses water pipes to heat and cool buildings on campus. While the cogeneration plant burns natural gas to produce electricity and steam heat for the campus, the new system will use electricity for both power and thermal needs. By using clean energy sources, such as wind and solar, to produce this electricity, the campus’s future power, heating and cooling needs would be entirely carbon-free.

The human penchant for storytelling is universal, early-developing, and profoundly culture-shaping. Stories (folk tales, narratives and myths) influence the costs of social transactions and organize societies at every scale of human interaction. Story as a mode of communication is also unprecedented in the animal kingdom: although we are compelled to tell stories about other animals, they are not likewise compelled to tell stories about us (or anything else, for that matter). Even our ability to manage urgent human problems such as global health and climate change are affected by the stories and myths humans choose to tell. This symposium explores several stories about how the evolution of story-telling shaped, and continues to shape, the human epoch.

Animals and tricksters are highly prominent beings in the mythology of the San Bushmen of southern Africa, as well as of hunter-gatherers in other regions of the world. Their actions and interactions provide the plot lines for most of the stories people tell about myth time. Why are these two beings so preeminent in San mythology and storytelling? Is there a connection between the two beings? Mathias Guenther discusses these two questions and the answer reveals a deep – and deep-rooted –mystical connection also between animals and humans. The hunting-gathering people that provide the cultural context for my talk are the San Bushmen of southern Africa, amongst whom I have done ethnographic field work. I will also consider hunter-gatherers from other parts of the world, both from present or recent times and from prehistory. These considerations may shed some light on certain aspects of prehistoric cave paintings.

Political, financial and environmental crises coupled to the rise of social media have, in recent years, created a perfect storm of mis- and disinformation that leverage long standing reservoirs of belief within and across communities. These stories on social media mirror face-to-face storytelling and other storytelling environments in that they allow for the negotiation of cultural ideology (norms, beliefs, values), yet they also change the scope, speed and amplification of that storytelling. Importantly, storytelling has real world effects, and often motivates people to take action. We present a graphical model of the underlying narrative frameworks, estimated from the data itself, and show how various network based methods can form the basis for understanding the narrative coherence—and their possible outcomes—even when the discussions on social media are incomplete and noisy, as conversations in real life often are.

Wind turbine blades are a major source of environmental pollution and waste. Learn how UC Davis is creating an ecologically sound solution for their disposal. Students, faculty and researchers in the Advanced Composites Research, Engineering and Science (ACRES) lab in the UC Davis College of Engineering are building compostable wind turbine blades from bamboo and mycelium, the root structure of mushrooms. While the researchers are currently focused on building a wind turbine blade prototype, incorporating mycelium into building materials could have larger implications for sustainable structures.

Welcome to our wine processing course — a hands-on journey into the art and science of winemaking. Get a behind-the-scenes look at how students learn to taste, blend, age, fine, filter and package their own wines, all under the guidance of industry professionals and seasoned faculty. Our students’ coursework transforms into practical skills needed in the wine industry. The course, a part of the university’s viticulture and enology program, is held in our Teaching and Research Winery, the most advanced and sustainable winery in the world. Sustainability is a recurring theme, with students exploring every opportunity to make their process greener. Stay tuned for the opportunity to taste the fruits of our students’ hard work and innovation. With new state legislation that recently passed, UC Davis will soon be able to sell student-made wine, bringing the vineyard to your table. Series: "UCTV Prime" [Science] [Show ID: 39217]
