Each year, landslides kill thousands of people around the world and cause catastrophic property damage. But scientists are still trying to better understand the circumstances that cause them. Doing so would go a long way toward helping people predict where landslides could occur and how severe they might be.

A study led by Seulgi Moon, a UCLA professor of Earth, planetary and space sciences, could be a significant step toward that goal.

Moon and Gen Li, a former UCLA postdoctoral scholar who’s now at Caltech, created a new method to understand how topographic stress — which occurs when tectonic plates beneath the Earth’s surface slide toward each other enough to change the landscape above —influence landslide events. Their research is published in Nature Geoscience.

The study is the first to combine information about natural processes that take place both on the surface of the Earth and at the tectonic level; previous research focused only on landslides caused by events like earthquakes and rain.

“We found that the magnitude of big landslides is affected by not only local conditions such as slope and precipitation but can be also affected by forces deep underground,” Moon said. “This implies that the interaction between what’s above and below the ground is important to better understanding surface processes of the Earth.”

For the study, the scientists developed a new adaptation of an existing technology called 3D topographic stress modeling in order to identify places deep below the Earth’s surface where rocks are weathered — meaning that they’re weakened by natural geological processes — or fractured. By identifying those spots, the model can determine which locations are most susceptible to landslides.

“Understanding earth science and geology will be critical to making mitigation plans for landslides,” Moon said.

Moon and Li conducted the research on the Longmen Mountains, on the Eastern Tibetan Plateau. Their approach uses high-resolution satellite images to detect the sizes and locations of landslides. Those satellite images are compared to the fracturing and weathering of rocks in the same locations, which Moon said can be predicted from the topography of the Earth’s surface.

Areas in which the underground bedrock is particularly weak or fractured may be vulnerable to a large landslide.

Moon’s technique, which uses high-resolution underground stress distribution data, enabled the scientists to locate fracturing that would otherwise not have been apparent because it’s so deep beneath the Earth’s surface — as much as 500 meters (or about 1600 feet) down. The high-resolution underground stress distribution data allows the researchers to distinguish areas below the ground that are damaged due to high stress.

The new technique also could be used to determine where highly sensitive construction projects — like storage facilities for nuclear energy or water — should (or shouldn’t) take place.

New digital exhibit explores Jewish history in Boyle Heights

In the 1930s, the Los Angeles neighborhood of Boyle Heights had the highest concentration of Jewish people west of the Mississippi. There were approximately 10,000 Jewish households in the area, which was about a third of Los Angeles’ Jewish population. But Boyle Heights was also one of the most diverse neighborhoods — home to many Mexican, Japanese, Armenian/Turkish, Italian, Russian and African American families.

The Jewish Histories in Multiethnic Boyle Heights exhibit gathers archival materials, artifacts and personal stories to explore the rich history of the Jewish community in this neighborhood, while also observing how those experiences coincided with the other diasporic communities that lived there.

“The history of this neighborhood really lives on in people’s hearts and minds … and basements,” said Caroline Luce, chief curator and associate director of the UCLA Alan D. Leve Center for Jewish Studies.

The Boyle Heights exhibit is part of the Mapping Jewish L.A. project, a decadelong partnership between the Leve Center, UCLA Library and Special Collections, University of Southern California and other community archives. Through digital tools and multimedia technologies, the project enables a broader understanding of the complex histories of the Jewish community in Los Angeles.

“Like all of our projects at Mapping Jewish L.A., this exhibit aims to open a new public space for the discussion and discovery of L.A.’s kaleidoscopic history,” Luce said. “It serves as a new mode of remembrance, one that is collaborative and inclusive, that nurtures intergenerational and interethnic understanding, and that strengthens the ties between UCLA and the local community.”

Below is a preview of what you will find in the extensive digital exhibit, which covers many aspects of Jewish life in Boyle Heights, from education to cars and community centers.

The first automobile to ever drive through Los Angeles did so through the streets of Boyle Heights on May 30, 1897. J. Philip Erie, a New York civil engineer, spent $30,000 to design, invent and build the first gasoline-propelled automobile carriage west of the Mississippi River. The drive started in downtown Los Angeles and ended at Erie’s home near Hollenbeck Park.

By the 1930s and ’40s, cars were necessary to access jobs that were located beyond the downtown industrial zone. After World War II, as freeway construction in and around the neighborhood began, Mexican Americans, Japanese Americans and Jews formed social clubs revolving around the automobile. These clubs would sponsor food and toy drives, car washes and community events in their neighborhood.

In the early 1920s, members of the Arbeter Ring (Workers Circle), a proletarian fraternal organization, and Jewish activists affiliated with the Cooperative Consumers League, a left-leaning cooperative buying club, created a place where Boyle Heights’ multiethnic residents could socialize, learn and organize. They called it the Cooperative Center, a large, three-story building near the corner of Brooklyn Avenue and Mott Street. There were several meeting rooms on the top floor; a large ballroom for lectures, rallies and social events in the middle; and a bakery and café on the ground floor. The building operated on a cooperative basis: Shareholder members voted democratically on administrative decisions, and union labor was employed throughout the building.

The Cooperative Center became a hub for neighborhood-based organizations and an important site of political organizing and social activities. The center hosted lectures by Upton Sinclair; organized meetings for the carpenters, furniture makers and bakers unions; and held social activities that blended consciousness raising, interethnic mingling and fundraising. Several unions and cultural organizations rented space there, as did the local branches of the International Workers Order, a left-leaning fraternal organization that offered low-cost insurance to its members regardless of race, religion or creed.

The origins of Mt. Sinai Hospital — part of today’s Cedars-Sinai Medical Center — can be traced to the 1918 pandemic, when a group of Jewish Angelenos provided kindness and comfort to the sick. The effort reflected the Jewish value of bikur cholim (“visiting the sick”) — a traditional halakhic (Jewish religious law) principle that deems alleviating the suffering of the ill and offering prayers on their behalf to be an important mitzvah (commandment or good deed). In 1920, the group established the Bikur Cholim Society and purchased a small home in Boyle Heights to provide round-the-clock care for the neighborhood’s “incurables.”

By the end of the decade, the Bikur Cholim Society moved into a large building on Bonnie Beach Place. Known as the Mt. Sinai Home for Chronic Invalids, the facility, which featured a kosher kitchen and small prayer room, provided a space for observant Jewish patients to receive care.

Similar to the community spirit of Mt. Sinai Hospital, the former Japanese Hospital, located at First and Fickett streets in Boyle Heights, reflects how Japanese Americans took care of others in their community. In the early 1900s, public health officials often associated disease with recent immigrants and certain ethnic groups, and they used race to determine how to administer public health programs. As a result, Japanese immigrants, who were viewed as the least able to assimilate compared to other immigrant groups, didn’t have access to mainstream health care.

To meet the needs of their community, Japanese medical professionals established the Turner Street Hospital in Little Tokyo in 1913. But as the Japanese American community continued to grow, so did the need for more substantive medical care. Five immigrant Japanese doctors decided to build a larger hospital with state-of-the art surgical facilities, and the Japanese Hospital opened on Dec. 1, 1929.

“Both institutions are examples of how immigrant residents in Boyle Heights worked together to meet the basic needs of the most vulnerable, including health care, shelter and child care,” Luce said. “By highlighting these overlapping patterns of community organization, we hope the exhibit illuminates the intersecting histories of the many diasporas that converged in Boyle Heights.”

In 1908, a group of Yiddish-speaking Jewish immigrants from Eastern Europe founded Los Angeles’ first Yiddish organization, the National-Radical Club. Among its primary goals was establishing a Yiddish school, so Jewish parents could supplement their children’s public school education. Advocates for the school included Dr. Leo Blass (née Lieb Isaac Shilmovich), whose devotion to Yiddish culture was legendary. Blass and members of the National-Radical Club began teaching classes at a private home near Michigan Avenue and Breed Street.

In 1920, Blass and the school board launched a fundraising drive to purchase a house at 420 N. Soto St., where the school would become a Yiddish cultural center and organizing space. The new center, known as the folkshul (“people’s school”), opened the following year with 120 students. In addition to being a Yiddish school, the folkshul quickly became a popular destination for organizations and events, hosting meetings of local Jewish unions, fundraisers and bazaars, and an annual Hasidism ball.

About a half mile from the folkshul was the Soto-Michigan JCC, the Jewish Centers Association’s new community center in Boyle Heights. The center’s director, Rabbi J. M. Cohen, wanted to expand the center’s role in the neighborhood to “integrate the Jewish community with the general community and the individual with the Jewish community and society as a whole.” Cohen believed that by celebrating cultural pluralism, the center would strengthen the Jewish identities of American-born children, foster integration and serve all of the neighborhood’s residents, including children of Mexican, Asian, Russian and African American descent.

The Soto-Michigan JCC’s three-story facility featured a lounge, game room and clubroom on the first floor and locker rooms in the basement. But the facility’s most popular feature was the Stebbins playground, where there was a jungle gym, volleyball and basketball courts, swing sets and pingpong tables. As many as 1,000 people regularly visited the Soto-Michigan JCC just to use the playground, in addition to the 2,300 children and adults who used the meeting rooms and auditoriums every week.

Lessons Learned: UCLA Symposium on Remote Teaching during COVID-19

Students haven’t been the only ones navigating a new college experience during the COVID-19 pandemic. For faculty, switching to fully remote teaching posed a challenge unlike anything they’d experienced before.

UCLA’s Center for the Advancement of Teaching, along with its partners CEILS, EPIC, and OTL,* hosted its third annual symposium for UC faculty and staff in April. “Teaching at UCLA – Looking Forward with 2020 Vision” featured panel discussions, talks and workshops centered on lessons learned during remote teaching since March 2020.

A central theme was how to keep students engaged in a virtual classroom. At the faculty roundtable, professors discussed the effects of holding classes and office hours virtually from home, with some noting that the newfound flexibility of remote teaching had enabled them to make stronger connections with students.

“[Remote teaching] brought us together in ways I have never experienced in 24 years at UCLA. I felt a level of humanity with my students that I had not experienced before,” said Abel Valenzuela Jr., professor of Chicana/o and Central American studies and of urban planning and director of the Institute for Research on Labor and Employment.

Valenzuela said that hosting virtual informal hangouts with his students to talk about anything on their minds was particularly impactful.

English professor Danny Snelson shared different gaming tools he used to make lectures fun and engaging for his students, including Discord, Animaze, Gather Town and Snap Camera.

Other faculty discussed the various ways they adapted their assignments and class organization to be mindful of the challenges of remote learning and the pandemic. Being flexible with deadlines, offering smaller, low-stakes assignments, and giving students space in discussions or journals to express their thoughts and concerns were all successful in keeping students engaged and supported.

Student panelists noted that although it was challenging to connect with their classmates in a virtual setting, working in small groups and spending more time discussing topics as a class helped them feel part of a community.

Imani Easton, graduate student in civil and environmental engineering, said that remote learning has equipped students with valuable communication skills that will prepare them for life after graduation.

“We’ve gotten to a point where we have to speak up and contribute. Before we used to just sit in lecture and take notes,” Easton said. “When we go back to campus, I’m looking forward to having more of a dialogue and open communication.”

David Schaberg, senior dean of UCLA College, dean of humanities and professor of Asian languages and cultures, said that despite the successes of remote learning, he wants to get as many people back on campus as possible.

“Nothing can truly replicate the excitement and personal growth students experience on a college campus,” Schaberg said. “We cannot give up the ideal of the campus space where people interact with their full selves. This is where students come to test out their adult selves, and you can’t do that online.”

UCLA Announces New Digital Hub For Globalizing Japanese Studies

In 2013, the UCLA Department of Asian Languages and Cultures faced a troubling possibility: its entire program in Japanese literature and culture might collapse. Both its faculty members in this popular field of study were being courted by an Ivy League institution, jeopardizing its efforts to hire a third faculty member.

In the years since, however, the Japanese humanities have emerged as one of the greatest success stories in UCLA’s Division of Humanities. In 2017 and 2019, the department succeeded in recruiting two additional scholars of Japanese film and kabuki, respectively, transforming its program into one of the most robust in the nation. And early in 2020, Uniqlo founder Tadashi Yanai gave $25 million—the largest individual gift in the history of the division—to endow The Yanai Initiative for Globalizing Japanese Humanities. Since its creation in 2014, The Yanai Initiative has been directed by Michael Emmerich, that third Japanese literature specialist to join the program.

In just eight short years, Emmerich and his colleagues have catapulted UCLA’s program in the Japanese humanities to global prominence through an impressive array of Yanai Initiative projects, including more than 70 academic and cultural events that have benefited not only students and faculty, but also the broader Los Angeles community. Today, UCLA is known as a hub for research in the field, attracting hundreds of graduate students, scholars, authors and artists to campus from all around the world.

Emmerich and The Yanai Initiative recently announced their intention to build on this record and on the networks they have developed by launching Japan Past & Present, a centralized digital hub for interdisciplinary and international research in Japanese humanities.

“This will really be a game changer,” Emmerich said. “Until now, it has never been possible to conceive of the Japanese humanities as a truly global field. Ironically, I think COVID-19 has helped us see more clearly that we can create truly meaningful intellectual bridges, and build an inclusive scholarly community, online. We want to seize this moment to do that.”

Embodying a vast, truly global vision, Japan Past & Present is a collaborative project of UCLA and Waseda University in Tokyo. It will bring together wide-ranging resources to benefit and facilitate communication among scholars in the Japanese humanities based around the world. The hub will include databases of translations and scholars, research materials, event notices, and a venue for mentorship and collegial advice. Emmerich and his colleagues also hope to create a system designed to open up access to primary and secondary materials in the Japanese humanities to scholars at institutions that can’t afford a subscription to the ILL system.

“This project exemplifies UCLA’s role as a public research university in making research widely accessible, and it furthers The Yanai Initiative’s aim of strengthening the Japanese Humanities as a global field,” said David Schaberg, senior dean of the UCLA College and dean of the humanities division. “Inviting the participation of scholars of all backgrounds, and from all different countries, will stimulate new research and intellectual exchange.”

Japan: Past & Present will consist of three “collectives” focused on premodern Japan, early modern Japan, and modern and contemporary Japan—more than a thousand years of history and cultural production.

Paula R. Curtis, a postdoctoral fellow at Yale University, is leading the development of the Premodern Japan Collaborative and has been instrumental in conceptualizing the project as a whole.

Japan Past & Present is an unprecedented effort to strengthen the ties between diverse communities of scholars from all around the world, and to make the Japanese Humanities more inclusive and equitable. It’s a daunting undertaking, but it’s also incredibly exciting,” Curtis said.

Toeda Hirokazu is co-director with Emmerich of The Yanai Initiative at Waseda and director of the Waseda International House of Literature, which will be hosting the digital hub.

“I’m delighted that The Yanai Initiative is launching this exciting project to help globalize the field of Japanese Studies, and look forward to more exciting developments as the project unfolds,” Hirokazu said.

Emmerich said the first stage of this enormous project, focused on premodern Japan, is currently underway and that he hopes to keep things moving rapidly ahead.

The Yanai Initiative, established through a major gift from Uniqlo founder Tadashi Yanai, is part of the UCLA Department of Asian Languages and Cultures and is a collaboration with Waseda University, one of Japan’s most prestigious universities. It supports academic research and cultural programming and facilitates student and faculty exchanges between the two universities.

Civic leader, social justice advocate and UCLA alumnus D’Artagnan Scorza will deliver the keynote address at the UCLA College’s virtual commencement celebration on Friday, June 11. The program, which begins at 6 p.m. PDT, will also feature remarks by Chancellor Gene Block, Nobel laureate Andrea Ghez, class of 2021 student speakers and others.

A decorated U.S. Navy veteran, Scorza is the inaugural executive director of racial equity for Los Angeles County and president of the UCLA Alumni Association. He is also a lecturer at the UCLA Fielding School of Public Health.

“D’Artagnan Scorza has given back to his fellow Bruins and his fellow Americans in myriad ways since his graduation,” said David Schaberg, senior dean of the UCLA College and dean of humanities. “His incredible life experiences and dedication to social change make him the ideal person to inspire our graduating seniors to aim high and make a difference in the world.”

In 2008, Scorza founded the nonprofit Social Justice Learning Institute and as its executive director over the next 12 years led efforts to open up academic and career opportunities to Black and Latino youth while establishing community gardens, a farmers’ market and healthy lifestyle centers in his hometown of Inglewood, California. His research, policy initiatives and grassroots organizing have had a significant impact on high-need communities throughout California.

“This year’s graduating class deserves so much credit for their achievement and resilience in the face of the pandemic,” Scorza said. “It’s an incredible honor to have been asked to give the commencement address to this remarkable group of Bruins.”

While studying as an undergraduate UCLA, Scorza enlisted in the Navy following the Sept. 11 terrorist attacks and served for four-and-a-half years, including a deployment to Iraq. He later returned to UCLA, where he completed his bachelor’s degree in the study of religion in 2007 and earned his doctorate in education in 2013. As a UC student regent from 2007 to 2009, he helped pass policies that established veterans’ service centers and prioritized $160 million for student services across UC campuses.

Scorza also served as president of the Inglewood Unified School District Board of Education and chaired a campaign to secure $350 million in school improvement bonds for the district’s schools.

Scorza was invited to be the 2021 commencement speaker after being selected from among wide field of candidates by UCLA’s Commencement Committee, which comprises students, faculty members and administrators.

Along with his UCLA degrees, Scorza holds a bachelor’s in liberal studies from National University in San Diego.

Virtual and in-person commencement ceremonies

In addition to the virtual celebration, UCLA plans to recognize members of the class of 2021 individually and in person at a series of events beginning the weekend of June 11; these events will be held over the course of several days and will adhere to public safety guidelines. For information on the in-person and virtual celebrations, please visit the UCLA College’s commencement website and UCLA’s campus commencement website.

Campus leaders announced in April that while the UCLA College and other units would be hosting commencement ceremonies virtually due to the continued public health risks of the COVID-19 pandemic, UCLA remains committed to hosting in-person commencement ceremonies for the classes of 2021and 2020 and their families and friends at a later date.

Migratory songbirds’ travels disrupted by earlier springs

Spring has arrived in North America. Leaves have sprouted, flowers are in bloom and migratory birds are bringing color and song to large swaths of the continent.

The timing of this so-called spring green-up — the beginning of a new cycle of plant growth each year — affects migratory birds’ behaviors and ability to survive their move north. They tend to travel later if winter lasts a little long, and sooner if spring comes early.

In North America, climate change is causing spring to arrive an average of 0.4 days earlier each year. According to a new paper in Nature Ecology and Evolution, some species could be unable to keep pace with this rapid change.

Although a change of less than half a day per year might not sound like much, it adds up to an entire week’s worth of change every 20 years, and it could alter what food is available along their migration routes and breeding grounds, how much time fledglings have to leave the nest, and how the birds interact with other plant and animal species. Previous research has found that such changes could lead to population declines and cascading effects to ecosystems.

“Some birds are quite accurate on the coming of spring because they are highly sensitive to the rhythms and cycles of nature,” said Morgan Tingley, a UCLA ecologist and the paper’s senior author.

Tingley and his co-authors crowdsourced 7 million observations by birdwatchers from the online platform eBird and compared the data to the timing of spring green-up as seen from space via two NASA satellites from 2002 through 2017.

The researchers analyzed how 56 species of migratory birds, primarily small songbirds, responded to these earlier springs. All species travel to breeding grounds in North America but some winter farther south, in the Caribbean, Central America and South America. The authors found that species with shorter, slower migration routes that winter farther north adjusted to changes better — the pine warbler and eastern phoebe, for example. Others had more trouble keeping pace, particularly those that winter in South America and have longer migration routes — such as the bobolink and willow flycatcher.

Most were unable to entirely keep up with an earlier arrival of spring. For each day earlier that green-up occurred, species generally adjusted their migration schedules by less than a half-day.

That inability to adjust to an earlier spring can have serious consequences, said Casey Youngflesh, the study’s lead author and a UCLA ecology and evolutionary biology researcher.

“If birds show up days or weeks later than optimal, they may not have enough food, which could result in lower success breeding and fewer chicks that survive to leave the nest,” Youngflesh said. “That’s really the main concern — that it may cause overall declines in how many birds there actually are.”

The study also notes that the consequences for birds could indirectly affect other animals and even plants. For example, caterpillars are a primary source of food for migratory birds, but if bird populations were to decline, it is possible that more caterpillars than normal would survive each year. Were that to happen, the health of trees could be affected because leaves are a primary food source for caterpillars.

“Everything is interconnected. If you remove a piece of the ecosystem, it’s hard to say exactly what will happen,” Youngflesh said, adding that further research would be needed to determine exactly what the consequences of earlier green-ups would be for any individual species.

Changes in climate have always been a major factor in the evolution of birds’ migratory patterns. However, Youngflesh said, those adaptations have occurred over tens of thousands, or even hundreds of thousands, of years. Modern climate change, largely resulting from increased carbon dioxide emissions, is happening far faster, over years and decades — so rapidly that many species are unable to adapt quickly enough.

That’s thought to be one of the primary reasons bird populations have declined rapidly across North America in recent decades. A 2019 paper published in Science concluded that the number of birds on the continent has diminished by about 3 billion since 1970, when the total population was around 7 billion. In addition to climate change, other factors such as habitat loss, outdoor-dwelling cats and more windows — with which birds collide — are likely reasons for the decline.

The new study, whose co-authors included researchers from the University of Florida, University of North Carolina and Pennsylvania State University and others, outlines a framework for further research into why and how the decline is happening, and it could help conservationists target their efforts to protect the species that are most at risk, Tingley said.

“Climate change is producing winners and losers,” Tingley said. “We are mapping for the first time why some are winning and others are losing.”

Venus is an enigma. It’s the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead.

Now, new observations from the safety of Earth are lifting the veil on some of Venus’ most basic properties. By repeatedly bouncing radar off the planet’s surface over the last 15 years, a UCLA-led team has pinned down the precise length of a day on Venus, the tilt of its axis and the size of its core. The findings are published today in the journal Nature Astronomy.

“Venus is our sister planet, and yet these fundamental properties have remained unknown,” said Jean-Luc Margot, a UCLA professor of Earth, planetary and space sciences who led the research.

Earth and Venus have a lot in common: Both rocky planets have nearly the same size, mass and density. And yet they evolved along wildly different paths. Fundamentals such as how many hours are in a Venusian day provide critical data for understanding the divergent histories of these neighboring worlds.

Changes in Venus’ spin and orientation reveal how mass is spread out within. Knowledge of its internal structure, in turn, fuels insight into the planet’s formation, its volcanic history and how time has altered the surface. Plus, without precise data on how the planet moves, any future landing attempts could be off by as much as 30 kilometers.

“Without these measurements,” said Margot, “we’re essentially flying blind.”

The new radar measurements show that an average day on Venus lasts 243.0226 Earth days — roughly two-thirds of an Earth year. What’s more, the rotation rate of Venus is always changing: A value measured at one time will be a bit larger or smaller than a previous value. The team estimated the length of a day from each of the individual measurements, and they observed differences of at least 20 minutes.

“That probably explains why previous estimates didn’t agree with one another,” Margot said.

Venus’ heavy atmosphere is likely to blame for the variation. As it sloshes around the planet, it exchanges a lot of momentum with the solid ground, speeding up and slowing down its rotation. This happens on Earth too, but the exchange adds or subtracts just one millisecond from each day. The effect is much more dramatic on Venus because the atmosphere is roughly 93 times as massive as Earth’s, and so it has a lot more momentum to trade.

The UCLA-led team also reports that Venus tips to one side by precisely 2.6392 degrees (Earth is tilted by about 23 degrees), an improvement on the precision of previous estimates by a factor of 10. The repeated radar measurements further revealed the glacial rate at which the orientation of Venus’ spin axis changes, much like a spinning child’s top. On Earth, this “precession” takes about 26,000 years to cycle around once. Venus needs a little longer: about 29,000 years.

With these exacting measurements of how Venus spins, the team calculated that the planet’s core is about 3,500 kilometers across — quite similar to Earth — though they cannot yet deduce whether it’s liquid or solid.

Venus as a giant disco ball

On 21 separate occasions from 2006 to 2020, Margot and his colleagues aimed radio waves at Venus from the 70-meter–wide Goldstone antenna in California’s Mojave Desert. Several minutes later, those radio waves bounced off Venus and came back to Earth. The radio echo was picked up at Goldstone and at the Green Bank Observatory in West Virginia.

“We use Venus as a giant disco ball,” said Margot, with the radio dish acting like a flashlight and the planet’s landscape like millions of tiny reflectors. “We illuminate it with an extremely powerful flashlight — about 100,000 times brighter than your typical flashlight. And if we track the reflections from the disco ball, we can infer properties about the spin [state].”

The complex reflections erratically brighten and dim the return signal, which sweeps across Earth. The Goldstone antenna sees the echo first, then Green Bank sees it roughly 20 seconds later. The exact delay between receipt at the two facilities provides a snapshot of how quickly Venus is spinning, while the particular window of time in which the echoes are most similar reveals the planet’s tilt.

The observations required exquisite timing to ensure that Venus and Earth were properly positioned. And both observatories had to be working perfectly — which wasn’t always the case. “We found that it’s actually challenging to get everything to work just right in a 30-second period,” Margot said. “Most of the time, we get some data. But it’s unusual that we get all the data that we’re hoping to get.”

Despite the challenges, the team is forging ahead and has turned its sights on Jupiter’s moons Europa and Ganymede. Many researchers strongly suspect that Europa, in particular, hides a liquid water ocean beneath a thick shell of ice. Ground-based radar measurements could fortify the case for an ocean and reveal the thickness of the ice shell.

And the team will continue bouncing radar off of Venus. With each radio echo, the veil over Venus lifts a little bit more, bringing our sister planet into ever sharper view.

This research was supported by NASA, the Jet Propulsion Laboratory and the National Science Foundation.

Other researchers who contributed to the study are Donald Campbell of Cornell University; Jon Giorgini, Joseph Jao and Lawrence Snedeker of the Jet Propulsion Laboratory; and Frank Ghigo and Amber Bonsall of the National Radio Astronomy Observatory in West Virginia.

Pulitzer Prize-winning author Ayad Akhtar will speak at the Luskin Lecture for Thought Leadership on Thursday, May 13 at 4 p.m. Following his remarks, Akhtar will take part in a conversation with Ali Behdad, UCLA’s John Charles Hillis Professor of Literature.

The online event is free and open to the public.

“This is an exciting opportunity to hear from one of the most creative and brilliant literary minds of our time,” said David Schaberg, senior dean of the UCLA College. “Ayad Akhtar is an outstanding storyteller and an incisive observer of the human experience, and we are honored to have him share his insights with us.”

Akhtar won the 2013 Pulitzer Prize for drama for his Tony-nominated play “Disgraced.” His other plays include “Junk,” which won the Edward M. Kennedy Prize for American Drama Inspired by American History and was nominated for a Tony, and “The Invisible Hand,” which earned an Obie Award, Outer Critics Circle’s John Gassner Award and Olivier Award.

Akhtar’s latest work is the novel “Homeland Elegies,” which explores the experiences of a Muslim man who, like the author, grew up in Wisconsin as the son of Pakistani immigrants. The Washington Post called it “a tour de force” and The New York Times noted it was “a beautiful novel … that had echoes of ‘The Great Gatsby’ and that circles, with pointed intellect, the possibilities and limitations of American life.”

Jennifer Mnookin, dean of the UCLA School of Law was one of the four UCLA deans who collectively chose to invite Akhtar to speak. She said “Homeland Elegies” was “the single most affecting, inspiring book” she has read during the pandemic.

“It is an extraordinary novel about the complexity of America, a beautiful interweaving of fact and fiction that explores identity, immigration, Islamophobia after 9/11, the process of literary creation and so much more,” Mnookin said. “It’s both a novel of ideas and a page turner.”

Akhtar’s first novel, “American Dervish,” has been published in more than 20 languages.

In 2017, Akhtar received an Arts and Letters Award for literature from the American Academy of Arts and Letters, the Steinberg Playwright Award and the Nestroy Theatre Prize. He has received fellowships from the American Academy in Rome, MacDowell, the Sundance Institute and Yaddo, for which he is also a board director. He is president of PEN America, the national nonprofit writers organization, and a board trustee at New York Theatre Workshop.

Eight faculty members, five of whom are from the UCLA College were elected today to the American Academy of Arts and Sciences, one of the nation’s most prestigious honorary societies. A total of 252 artists, scholars, scientists and leaders in the public, nonprofit and private sectors were elected to the academy today, including honorary members from 17 countries.

UCLA College’s 2021 honorees are:

Barbara Geddes, professor emeritus and former chair of political science, conducts research on the breakdown of authoritarian regimes, democratization, authoritarian transitions and political development, with a focus on Latin American politics. Geddes’ early work included studies of bureaucratic reform and corruption in Brazil and the politics of economic policy-making in Latin America. Early conclusions from her research about regime duration and modes of transition were published in “What Do We Know about Democratization after Twenty Years, Annual Review of Political Science 2” (1999). Geddes also published a book on comparative political research methods called “Paradigms and Sand Castles: Theory Building and Research Design in Comparative Politics” (2003).

Kelly Lytle Hernández, a professor of history and African American studies, is the director of UCLA’s Ralph J. Bunche Center for African American Studies. Lytle Hernández was awarded a 2020 MacArthur Fellowship from the John D. and Catherine T. MacArthur Foundation, which said her research on “the intersecting histories of race, mass incarceration, immigration, and cross-border politics is deepening our understanding of how imprisonment has been used as a mechanism for social control in the United States.” One of the nation’s leading experts on race, immigration and mass incarceration, she is the author of the award-winning books, “Migra! A History of the U.S. Border Patrol” (University of California Press, 2010), and “City of Inmates: Conquest, Rebellion, and the Rise of Human Caging in Los Angeles” (University of North Carolina Press, 2017). She holds UCLA’s Thomas E. Lifka Chair in History, and is the principal investigator for Million Dollar Hoods, a university-based, community-drive research project that maps the fiscal and human cost of mass incarceration in Los Angeles.

Daniel Posner, UCLA’s James S. Coleman Professor of International Development, focuses his political science research on ethnic politics, research design, distributive politics and the political economy of development in Africa. His most recent co-authored book, “Coethnicity: Diversity and the Dilemmas of Collective Action,” (Russell Sage, 2009) employs experimental games to probe the sources of poor public goods provision in ethnically diverse communities. His first book was “Institutions and Ethnic Politics in Africa.” (Cambridge, 2005). He is the co-founder of the Working Group in African Political Economy, a member of the Evidence in Governance and Politics network, a faculty associate of the Center for Effective Global Action and a research affiliate of the International Growth Center.

Marilyn Raphael, professor of geography and interim director of the UCLA Institute of the Environment and Sustainability, is the co-author of the award-winning book “The Encyclopedia of Weather and Climate Change: A Complete Visual Guide,” and the author or co-author of more than 60 peer-reviewed journal articles. Raphael was elected vice president of the American Association of Geographers, the world’s largest geography society effective July 1 of this year. Her research expertise includes atmospheric circulation dynamics, Antarctic sea ice variability and global climate change. She has been committed to introducing undergraduates to the world of climatology and graduate students to the joys of research.

Victoria Sork, is a distinguished professor of ecology and evolutionary biology and a renowned plant evolutionary biologist. Sork was award the 2020 Molecular Ecology Prize, which recognizes an outstanding scientist who has made significant contributions to the field. Elected in 2004 as a fellow of the American Association for the Advancement of Science, she has conducted pioneering research in the field of landscape genomics, which integrates genomics, evolutionary biology and conservation science. She is particularly concerned with the ecological and genetic processes that will determine whether California oaks will tolerate climate change. She and members of her laboratory conduct research throughout California and Western North America from Baja California through Alaska. Research she led in 2019 examines whether the trees being replanted in the wake of California’s fires will be able to survive a climate that is continuing to warm.

Other UCLA 2021 honorees are:

Terence Blanchard, a six-time Grammy-winning jazz trumpeter, composer and music educator, holds UCLA’s Kenny Burrell Chair in Jazz Studies in UCLA’s Herb Alpert School of Music. Blanchard has released 20 solo albums and composed more than 60 film scores. Blanchard served as artistic director of the Thelonious Monk Institute of Jazz (now named the Herbie Hancock Institute of Jazz) from 2000 to 2011. In this role, he presented masterclasses and worked with students in the areas of artistic development, arranging, composition and career counseling. Today, the institute partners with music school to offer the Herbie Hancock Institute of Jazz Performance at UCLA, a special college-level program that allows masters of jazz to pass on their expertise to the next generation of jazz musicians.

Elisabeth Le Guin, professor of musicology in the UCLA Herb Alpert School of Music, is a Baroque cellist, and was a founding member of Philharmonia Baroque Orchestra and the Artaria String Quartet. In recent years, Le Guin has become involved in the movimiento jaranero, a transnational grassroots musical activism in Mexico and Mexican immigrant communities in the United States. She has written two books, “Boccherini’s Body: an Essay in Carnal Musicology” (2006) and “The Tonadillo in Performance: Lyric Comedy in Enlightenment Spain” (2014), both published by UC Press. She received the American Musicological Society’s Alfred Einstein and Noah Greenberg Awards. She re-started UCLA´s Early Music Ensemble in 2009 after a 15-year hiatus.

Kimberlé Crenshaw, a distinguished professor of law in the UCLA School of Law, is an expert on race and the law, structural racism and discrimination based on race, gender and class. A renowned scholar on civil rights and constitutional law, Crenshaw was a founder and has been a leader in the intellectual movement called critical race theory. She is the executive director of the African American Policy Forum, an innovative think tank connecting academics, activists and policy-makers to dismantle structural inequality and engage new ideas and perspectives to transform public discourse and policy. Crenshaw coined the term “intersectionality” more than 30 years ago to describe how race, class, gender, and other individual characteristics “intersect” with one another and overlap.

“We are honoring the excellence of these individuals, celebrating what they have achieved so far and imagining what they will continue to accomplish,” said David Oxtoby, president of the academy. “The past year has been replete with evidence of how things can get worse; this is an opportunity to illuminate the importance of art, ideas, knowledge and leadership that can make a better world.”

The American Academy of Arts and Sciences was founded in 1780 by John Adams, John Hancock and others who believed the new republic should honor exceptionally accomplished individuals. Previous fellows have included George Washington, Benjamin Franklin, Alexander Hamilton, Ralph Waldo Emerson, Albert Einstein, Charles Darwin, Winston Churchill, Martin Luther King Jr., Nelson Mandela and UCLA astrophysicist Andrea Ghez.

It also is an independent policy research center that undertakes studies of complex and emerging problems. Current academy members represent today’s innovative thinkers in many fields and professions, including more than 250 Nobel and Pulitzer Prize winners.
