Join world-renowned researcher Dr. Alberto Burquez for a free presentation on giant columnar cacti, including Arizona's iconic saguaros. Dr. Burquez will detail his research on their evolutionary history, ecology, adaptations to the Sonoran Desert, and the effects of climate change.

A researcher at the Universidad Nacional Autónoma de México (UNAM), Dr. Burquez is a co-author of "The Saguaro Cactus: A Natural History" and an expert in columnar cacti population ecology and genetics. His work also covers plant-animal relationships and land-use change in the Sonoran Desert.

Dr. Morgan Levine, author of "True Age," outlines three dietary factors for longevity: quantity, quality, and timing. Caloric restriction (a 20% reduction) has shown lifespan benefits in animals, possibly by preventing overeating. A plant-based diet, rich in fruits, vegetables, and whole foods while limiting animal products and refined sugars, is also beneficial. Fasting, or time-restricted eating, may mimic caloric restriction benefits via 'hormesis,' boosting resilience to aging.

Optimal diet is individual, influenced by genetics and age, and should be monitored via biological age and well-being. Dr. Levine, a former Yale professor now at Altos Labs, researches aging systems. For more, watch "The science of super longevity" or read the transcript on Big Think.

Ali Moore from RELondon (formerly London Waste and Recycling Board) discusses their work advancing London's circular economy. They collaborate with government, businesses, and citizens, promoting initiatives like 'Eat Like a Londoner' to reduce food waste and encourage plant-rich diets.

The Ellen MacArthur Foundation, a UK charity, develops and promotes the circular economy concept: designed to eliminate waste and pollution, circulate products and materials, and regenerate nature.

After five years of legal action by the Center for Biological Diversity, the U.S. Fish and Wildlife Service finalized Endangered Species Act protection for the Dixie Valley toad. These extremely rare amphibians, previously under emergency protection, face acute threat from a geothermal power plant likely to dry up their critical hot springs. As the Center’s Great Basin Director Patrick Donnelly stated, "Renewable energy is essential to combating the climate emergency, but it can’t come at the cost of extinction."

In 8th grade, Lauren U.C. Ejiaga's science fair project on ozone depletion and Louisiana's marsh grasses won a top prize at Broadcom MASTERS. This experience highlighted the importance of environmental awareness alongside research, inspiring her to educate peers.

Now 17, Lauren leads multiple native plant restoration projects as a cohort leader for the Coalition to Restore Coastal Louisiana. She also founded the "Conservation and Restoration Conjunction," a series of workshops promoting STEM education and coastal protection among youth. She recruits national science fair winners to speak about STEM careers.

Ecological restoration is challenging, with many advanced technologies being costly and complex. However, effective, low-tech "old school" methods have been successfully employed by land managers

Ecological restoration is challenging, with many advanced technologies being costly and complex. However, effective, low-tech "old school" methods have been successfully employed by land managers for decades.

Dr. Elise Gornish, a UA restoration ecologist, will share these accessible techniques, from seed balls to rock lunas, for restoring disturbed ecosystems. Her work focuses on arid land restoration and integrating approaches into weed management. She also directs UA GALS, a program offering STEM leadership to underserved female high school students.
