NASA scientists utilized 30 years of Landsat satellite data to track vegetation changes across 4 million square miles of Alaska and Canada. Their findings reveal a significant "greening" trend, with 30% of the area showing increased vegetation, while only 3% experienced "browning."

This pioneering study, the first to provide continent-scale detail alongside local information, underscores the impact of rapid Arctic warming. Elevated temperatures lead to extended growing seasons and altered soils, transforming tundras into shrublands. Future research will investigate local factors influencing these greening patterns and explore forested regions.

"Billion Dollar Crop," a 1994 Australian documentary, explores the history, diverse uses, and future of cannabis, focusing on the versatile and potentially revolutionary plant's potential.

The film highlights how recently developed, non-drug hemp varieties are being researched and cultivated globally for their versatile qualities and environmental benefits. It showcases hemp as an industrial fiber, offering alternatives to wood for paper, cotton for clothes, and plywood for construction, thereby benefiting forests and topsoil.

Produced with Michael Cordell and Jeffrey Bruer, and directed by Barbara Ann Chobocky, the DVD is available from Bull Frog Films.

Collapsing ice shelves and calving icebergs in Greenland and Antarctica are now major drivers of sea level rise. The speed of these changes highlights significant gaps in our understanding of how ice sheets respond to climate change, largely due to insufficient measurements from glaciers' marine edges.

For over a decade, Fiammetta Straneo and her Scripps Institution of Oceanography team have probed Greenland's calving glaciers using diverse vehicles. Their research provides crucial data, improving models and sea-level rise predictions. This presentation was recorded on May 13, 2019, as part of the "Jeffrey B. Graham Perspectives on Ocean Science Lecture Series."

6G cellular networks will be highly complex, requiring deep learning (DL) to achieve significant system-level gains through site-specific communication techniques. Prof. Jeffrey Andrews will present his group's DL innovations for 6G. These include a novel beam alignment approach offering up to 1000x speedup, a new architecture for high-dimensional channel estimation using deep generative networks, and site-specific multicell optimization that rapidly learns near-optimal antenna array settings, outperforming conventional 3GPP methods.

Dr. Jennifer Smith and entrepreneur Brant Chlebowski discuss their collaborative applied aquaculture research on commercially valuable seaweeds. This groundbreaking work sparked the formation of the California Seaweed Company and initiated new research in Smith's lab focusing on local seaweeds for food and feed applications.

This talk explores Sunset Crater, Arizona's youngest volcano, erupted 940 years ago, impacting the Sinagua people. Geologist Dr. Jeffrey Meyer will share its story and his work mapping the unique Bonito lava flow, notable for traveling uphill.

Understanding this flow aids hazard prediction and interpreting past flows on Earth, the Moon, and other planets. Dr. Meyer, a retired geology instructor, became curious about the Bonito flow, leading to detailed mapping via Lidar.
