Glaciers and Sea Level Rise

Using helicopters, icebreakers, fishing vessels, and autonomous surface and underwater vehicles for over a decade, Fiammetta Straneo and her group have been probing the edge of massive calving glaciers in iceberg-choked fjords in Greenland to explore what is the Achille’s heel of glaciers – the marine edge where glaciers meet the sea.

Their goal? Collapsing ice shelves and calving of large icebergs in Greenland and Antarctica have recently become major drivers of sea level rise. The rapidity of these changes has come as a surprise, revealing major gaps in our understanding of how ice sheets respond to a changing climate. To a large extent, these gaps are due to a lack of measurements so Fiammetta and her group have probed in these polar environments to improve models of sea-level rise predictions.

Taking the Lead

Madeleine Albright was born in Czechoslovakia and emigrated with her parents to the United States at age eleven. She first rose to public prominence in 1993 as U.S. ambassador to the United Nations, and in 1997 she was appointed as the nation’s first female Secretary of State by President Bill Clinton. In 2012 she was awarded the nation’s highest civilian honor, the Presidential Medal of Freedom, by President Barack Obama. Now a professor of diplomacy at Georgetown University, Albright has remained active as an author, lecturer, and international envoy.

In her Commencement address to UC San Diego graduates Albright stresses the need to build communities, both locally and globally, and the importance of public service – topics on which she is eminently qualified to speak, having spent her adult life as a diplomat and dedicated public servant. As Secretary, Albright was an articulate advocate for democracy, human rights, fair labor practices, environmental protection, and global trade, and in her talk she notes that these core values align precisely with UC San Diego’s institutional philosophy and mission goals.

She urges the assembled students to become actively involved in public life and to assume leadership roles in addressing such serious issues as income inequality, climate change, nuclear proliferation, peace in the Middle East, terrorism, and, of course, immigration reform, noting that in addition to being the first female Secretary of State she is herself an immigrant. Albright emphasizes that the interconnectedness of today’s world heightens the need for thoughtful communal consensus in formulating new strategies and policies, and that UC San Diego graduates are well-disposed to effect those changes.

Women in Leadership 2019

“Where on an imagined clock of equality do we now stand?” asks veteran journalist Lynn Sherr at the start of this year’s Women in Leadership panel.

Listen in as Sylvia Acevedo, Chelsea Clinton, Jedidah Isler answer that question and share their thoughts on the present and future of the role of women in America. Each panelist reflects on her road to leadership and details the support mechanisms and mindsets needed to get there when faced with adversity.

This is the second annual Women in Leadership panel – convened to celebrate and honor the legacy of Sally Ride, the first American woman to fly in space.

Ethics and Social Science

“We’re not just playing games in empty classrooms anymore,” says Scott Desposato, professor of political science at UC San Diego.

As the world of social science is increasingly reaching beyond the traditional college campus setting for their studies, new ethical questions are emerging. Sure, large amounts of data can be gathered in massive scale field experiments but are we neglecting the principles of informed consent? How should science and society work together to break new ground while pushing innovative thought forward? Explore these questions and more in this program.

Engineering Mosquitos to Fight Malaria

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.
