UCSF has a long history of pioneering biomedical research and a bold vision for advancing science and seeking new ways to improve health care delivery nationwide. But, what does that actually mean in the near future and beyond?
This new series, part of the popular Mini Medical School for the Public, takes you inside the work of UCSF scientists to learn what the next decade may bring to the world of medicine. Hailing from a wide spectrum of disciplines, each explores a different topic that has the potential to impact the future of healthcare.
UCSF was the only medical school to be ranked in the top five in the nation in both research and primary care by US News and World Report, ranking fifth in biomedical research and third in primary care education. UCSF was also the only medical school ranked in the top five in all eight of the specialty areas covered by the survey in 2019.

Unlike most other animals, much of human brain development and maturation occurs after birth, a process that continues into early adulthood. This unusual pattern allows for greater influences of environment and culture on the emergence of the adult mind.
This series of programs from the recent CARTA symposium addresses the interactive contributions of nature and nurture in this process, ranging from experiments by ancient monarchs and lessons from “feral” children of various kinds, to the follow-up on Romanian orphans.
Distinguished speakers address comparative and neurobiological issues which likely played a key role in the origins of the human species and in the evolution of distinct features of our minds.

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.

Svante Pääbo once said, “We are all Africans, either living in Africa or in recent exile from Africa.”
It is now abundantly clear that Africa was the “cradle of humanity,” with multiple waves of hominins arising on that continent and spreading across the old world, eventually being effectively displaced by our own species, which also arose in Africa.
Given these facts, it is not surprising that the strong emphasis of anthropogeny is on the continent of Africa with wide-ranging studies including genetic, paleontological, archeological, primatological, climatological, sociocultural and more.
This CARTA symposium focuses on the contributions of scientists and scholars of anthropogeny who live and work in Africa.

Mosquitos are the deadliest animal on Earth. They spread diseases like yellow fever, chikungunya, West Nile virus and malaria. Malaria alone killed 435,000 people and infected another 219 million in 2017 according to the World Health Organization. There are widespread efforts to combat mosquito-borne illnesses, including revolutionary new gene editing techniques.
Ethan Bier and Valentino Gantz, biologists at UC San Diego, have been researching gene drives – systems that allow scientists to quickly push genes through entire populations. Typically, genetic information from each parent is combined and passed down to their children. Think back to Punnett squares from high school biology. If one parent has blonde hair and the other has brown hair, the brunette would have to carry a recessive blonde gene for any of their children to be blonde. But, gene drives change that. Gantz and Bier came up with a way to use the CRISPR gene-editing technique to insert self-editing genes into mosquitos, so preferred traits are always passed down. Their research shows these traits can take over entire populations within 10 generations, one to two years for mosquitos.
In a recent talk at UC San Diego Extension’s Osher Lifelong Learning Institute, Bier dove into the details of exactly how gene drives work, and their many potential applications.
