The Future of our Oceans

Ours is a water planet. Technology is shaping our uses, both as foe and ally. It has made humans the dominant predator and provides us food, gives us half the oxygen we breathe and created many maritime jobs. But technology has also raised CO2 levels, caused acidic oceans, threatened ocean biodiversity and created grand climate challenges.

Marine biologists like Doug McCauley at UC Santa Barbara are also using technology to promote ocean health and provide a balance. In this talk, McCauley describes examples of technology used to help the oceans and marine biodiversity. He shows systems that track whale activity and communicate it to ships so they know where to slow down to avoid collisions. He describes technology to monitor marine protected areas, image recognition techniques to study the endangered giant sea bass and electronic tags to follow sharks.

McCauley began his career as a fisherman in the Port of Los Angeles. Eventually he migrated to marine science and UC Santa Barbara. McCauley has degrees in political science and biology from the UC Berkeley. His PhD research was done at Stanford University where he studied the ecology of sharks, giant parrotfish, and coral reef ecosystems. McCauley’s science is motivated by the belief that we must better understand how complex ocean ecosystems work if we want to better protect them from threats like overfishing, climate change, and pollution.

Bone Health: Beyond Supplements

“This is what I learned when I thought I knew everything already about healthy eating and living,” says Vicky Newman, MS, RDN. Her informative talk goes beyond the basics of calcium intake for bone health to highlight the importance of a healthy diet combined with physical activity. Learn about the exercises that increase weight bearing and strength in addition to activities to improve your balance. Get insights into what a bone-healthy diet looks like and how to work with your doctor to minimize medications that could be taking a toll on your bones.

“Boosting Bone Health to Prevent Injury and Speed Healing” marks the 2019 return of the Stein Institute for Research on Aging lecture series to UCTV. For more with Vicky Newman, and to view the complete archive of lectures, visit https://uctv.tv/stein/.

The Dr. Seuss You Never Knew

The 2019 edition of UC San Diego Geisel Library’s “Dinner in the Library” series celebrates new acquisitions from the estate of Theodor “Dr. Seuss” Geisel, most of which have never before been exhibited publicly. The Library’s Special Collections already houses over 20,000 items related to Geisel, including sketches, paintings, cartoons, letters, and manuscripts, and these new arrivals will further enhance its status as the world’s premiere repository of Seuss miscellany.

University Librarian Erik Mitchell welcomes a distinguished panel to discuss their reactions to the unveiling of Geisel’s “private art.” Seth Lerer, moderator and Distinguished Professor of Literature at UC San Diego, traces the development of Geisel’s stylistic vocabulary though doodles and rough sketches not intended for publication, and invites fellow panelists and the audience to consider the proper placement of these works within Geisel’s larger oeuvre. Rob Sidner, Executive Director of the Mingei International Museum, notes that many of the new acquisitions were exhibited in Geisel’s home and speculates on their personal significance to the artist. Mary Beebe, Director of the Stuart Collection at UC San Diego, discusses Geisel’s acrylic paintings on display, noting they are uncharacteristic of Geisel and yet valuable for that reason. Beebe also cites Geisel’s delight in wordplay as a consistent feature of his work.

Other topics featured in this wide-ranging discussion include the challenges of exposure to a hitherto-unknown facet of an artist’s work, influences on Geisel’s development such as theatre and Surrealism (most notably Salvador Dali), the underlying social commentary in many of Geisel’s cartoons and books, his frequent portrayals of “sympathetic monsters,” and the importance of acknowledging that, in Seth Lerer’s words, “not everything in this collection is happy or funny; some of it is in fact quite dark.”

Theodor Geisel famously maintained that he wrote his books for adults, and that their adoption as beloved icons of children’s literature was a fortunate happenstance. The new additions to the Geisel Library’s Special Collections contribute to a fuller portrait of this complex and prolific artist, one possessed of considerable skills whose range of styles and thematic concerns is greater than previously appreciated.

Spotting the Warning Signs of Kawasaki Disease

It is one of the most common causes of acquired heart disease in pediatrics, yet very little is known about Kawasaki Disease. It was discovered by Dr. Tomisaku Kawasaki in Japan in the 1960s. It has since been documented around the world, including a spike in cases in San Diego earlier this year. Yet, the cause of Kawasaki Disease remains a mystery.

Dr. Jane Burns is the director of the UC San Diego Kawasaki Disease Research Center, and one of the leading experts on the disease. She sat down to discuss her research, and what parents need to know about Kawasaki Disease with Dr. David Granet on Health Matters. She says because it starts off with a sudden high fever, Kawasaki Disease can often be misdiagnosed as a common virus. But, parents can easily spot the telltale symptoms in the following days: bloodshot eyes, bright red mouth and lips, swollen and red hands and feet, and body rash.

When untreated, one in four children with Kawasaki Disease will develop permanent, potentially fatal heart disease. Those complications can usually be avoided with proper treatment, but it’s expensive and out of reach for millions of children around the world. That’s why Dr. Burns and her team continue to investigate the mysterious disease.

How a Year in Space Affects the Human Body

Science fiction has long promised an age of interplanetary human existence. Scenes of spaceships hopping from one galaxy to the next are so common, it seems almost inevitable that future generations will one day vacation on Mars. But, if we are ever going to achieve life on other planets, we first have to figure out if the human body can tolerate it.

Some of the best data we have on the subject comes from American astronaut Scott Kelly. Kelly spent a year living on the International Space Station while his twin brother Mark, also an astronaut, was on Earth. Scientists from all over the country studied the impact life in space had on Scott Kelly, and compared changes in his body to his brother.

One of those scientists was UC San Diego Professor of Medicine, Michael G. Ziegler, MD. In a recent talk at UC San Diego Extension’s Osher Lifelong Learning Institute, Ziegler detailed some of the more interesting findings from the study. Scott Kelly lost weight. There were significant changes to his gene expression. He lost collagen. His carotid artery thickened. His bones became less dense. His eye shape changed, forcing him to wear glasses. While he was in space, his performance on cognitive tests improved. But, his performance plummeted after returning to Earth, and never quite returned to pre-launch levels.

Despite all of this, Ziegler has reason to be hopeful about long-term space travel. He says the year in space study illuminated many of the challenges, and gave researchers some ideas of how to overcome them. Still, it’s probably a little early to start planning your trip to the red planet.
