The Science Café line-up features a series of informative presentations given by University of Arizona researchers on topics that affect you, your family, and our world. Each presentation is followed by the opportunity for those in the audience to ask questions and personally meet our scientists. Attendees are encouraged to bring their food and enjoy the shade.
2019 Saturday Line-up
10:30am Planetary Defense: Are We Prepared for the Next Impact?
Impacts due to asteroids and comets have shaped the course of evolution on Earth. While the threat due to impacts is minimal during human lifetime, their stochastic nature makes them hard to ignore. The talk will summarize the results of the first global planetary defense exercise where many nations participated to detect and track a near-Earth asteroid as if it was an impactor. Prof. Reddy led this global campaign and will summarize how well the Earth is prepared for the next asteroid impact. By Vishnu Reddy, Professor of Planetary Science, UA Lunar & Planetary Laboratory
12:00pm Inflammation Nation: Eating and Lifestyle Approaches to Address the Inflammation Epidemic
This nutrition research examines how genetic and epigenetic variations interact with human diets, (especially the modern Western diet) to drive inflammatory disorders, such as cardiovascular disease, cancer and depression. Discover how these individualized and population-based, research approaches provide solutions to overcome physical and emotional suffering so that people can live better, more joyful lives. By “Ski” Floyd Chilton, Director, UA Precision Wellness Initiative; Associate Director, The BIO5 Institute
1:30pm NASA's OSIRIS-REx Encounters Asteroid Bennu: Mission Highlights
This near-Earth, asteroid mission hopes to reveal how the Solar System formed and identify materials important to life on Earth by collecting a sample of asteroid Bennu. Once a suitable site is selected, the spacecraft will collect a pristine sample from the surface. The precious sample will return to Earth in 2023. The first images and data confirm ground-based observations and reveal an exciting world with intriguing surprises. Join us on this fantastic voyage! By Dolores Hill, Sr. Research Specialist, UA Lunar & Planetary Laboratory
3:00pm Tree-Rings, Cosmic Radiation and Resolving an Ancient Volcanic Controversy
This talk will introduce a long running scientific debate over the date of a volcanic eruption which took place more than 3000 years ago in the Ancient Mediterranean. We’ll discuss the scientific process and what happens when different lines of evidence do not agree. We will learn why dating the Minoan eruption of Thera is so important and how University of Arizona researchers are shedding new light to resolve this long running problem. By Charlotte Pearson, Assistant Professor, UA Laboratory of Tree-Ring Research
4:30pm How Beer Created Society, Trade, Microbiology, Basically Everything
Over 5000 years ago, in ancient Mesopotamia, human beings enjoyed a new invention of biotechnology, beer! Over the millennia humans have tirelessly worked to understand, improve, and perfect the beer-making process. Along the way, we have discovered new fields of study including enzymology, microbiology, biochemistry, and molecular biology. Today, the study of fermentation is hardly complete and many cutting-edge technologies owe their existence to a beverage that has captivated the human imagination for thousands of years. By Mike Mallozzi, Co-founder and President of Borderlands Brewing, Research Associate, UA Animal and Comparative Biomedical Sciences
Following the talk, join us for: March for Science SoAZ Science Trivia: Team Competition for Fun and Prizes!
2019 Sunday Line-up
10:30am Novel Treatments for Voice Quality As We Age
Learn about innovative tools for understanding and treating age-related voice disorders. Use of high-speed video, computational modeling and more inform therapy practices. Engage in fun and creative ways for improving voice quality. By Robin Samlan, Assistant Professor, UA Department of Speech, Language, and Hearing Sciences; UA Department of Otolaryngology Head & Neck Surgery
12:00pm Healing Spaces: The Science of Place, Wellbeing and Performance
Does the world make you sick? Do jarring sights and sounds trigger or reduce stress, induce anxiety, or instill peace? All can affect the healing chemistry of your mind. Your surroundings may also have the power to heal. This talk will explore the astonishingly, rich nexus of mind and body, perception and place. Learn how research findings from this ground-breaking work has stimulated new approaches for designing buildings and communities that support health and wellbeing for all. By Esther Sternberg, Research Director, Arizona Center for Integrative Medicine; Founding Director, UA Institute on Place, Wellbeing & Performance; Research Professor of Medicine, UA College of Medicine and Psychology
1:30pm The Galilean Satellites of Jupiter: Four Unique Worlds
The four large moons of Jupiter—Io, Europa, Ganymede, and Callisto—exhibit some of the most interesting phenomena in the solar system. The icy moons Europa, Ganymede, and Callisto probably have subsurface oceans of water, perhaps habitable, especially in Europa. Io may have a subsurface magma ocean feeding its hundreds of active volcanoes. Future missions are in development to explore Europa (NASA’s Europa Clipper mission) and Ganymede (the European JUICE mission), and a mission concept to Io will also be discussed. Be the first to hear about these exciting worlds and future missions. By Alfred McEwen, Professor, UA Lunar and Planetary Laboratory
3:00pm Biosphere 2: Science for the Future of our Planet
The world’s largest, controlled environmental research facility is dedicated to understanding how our unique planet works. As climate and ecosystems change in Biosphere 1 (Earth!) we can use Biosphere 2 and its large-scale ocean, rainforest, and other model biomes to explore the future of water, energy, and nutrients – and how humans may be affected. By Kevin Bonine, Director of Education and Outreach, Biosphere 2; Director of Outreach Initiatives, UA College of Science
