This episode of TecHype features Yoel Roth, former Head of Trust and Safety at Twitter. Yoel provides first-hand insights into how one of the largest online platforms in the world built out its trust and safety operations to better ensure its service was helpful, harmless, and aligned with user expectations

While at Twitter, Dr. Roth found himself the target of a coordinated harassment campaign on the platform, one instigated by the current CEO Elon Musk. His years of work building out the trust and safety operations had become personal. In this episode, Dr. Roth provides professional and personal perspectives on the real benefits and risks of platform trust and safety efforts, the current state-of-the-art of the field, and where it’s going.

Aparna Bhaduri, Ph.D., shares insights into human brain development and its intricate processes. Explore the intriguing reappearance of developmental cell elements in brain cancers like glioblastoma. Series: "Stem Cell Channel" [Health and Medicine] [Science] [Show ID: 38329]

UC Davis Professor, Dr. Frank Mitloehner, and CLEAR Center members took to Mexico to attend the Congress Internationale de la Carne in León, Guanajuato, Mexico, where they met and discussed sustainability efforts with the Minister of Agriculture. In addition to meeting with beef cattle producers and others in the livestock industry to share research coming from the UC Davis CLEAR Center, we got to tour feedlots and discuss sustainable practices that are currently being implemented. For example, rotational grazing can improve forage quality and soil carbon sequestration while implementing shade for cattle can improve efficiencies in production, and promote animal welfare.

TecHype is a groundbreaking series that cuts through the hype around emerging technologies to get to what matters. Each episode debunks misunderstandings around emerging tech, provides insight into benefits and risks, and identifies technical and policy strategies to harness the benefits while mitigating the risks of emerging technologies. This episode of TecHype features Prof. Hany Farid from UC Berkeley, a world-renowned expert in the analysis of digitally manipulated images. We take a deep dive into determining what a 'deepfake’ is and explore how these AI-generated images, videos, and audio can be used for both amusing and alarming purposes.

Farid highlights the increasing prevalence of deepfakes and their impact on society. From revolutionizing the entertainment industry, bolstering creativity, and championing advocacy campaigns to their use in impersonating public figures in ways that manipulate elections or personal contacts to commit fraud. The episode concludes with a discussion of targeted strategies that can be pursued to keep you safe from harmful deepfakes, such as digital watermarking and detection tools.

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.
