Anastassia Alexandrova, UCLA professor and vice chair of chemistry and biochemistry, has been selected to receive the Max Planck-Humboldt Medal, which honors extraordinary scientists outside Germany with outstanding future potential.

The medal, awarded jointly by Germany’s Max Planck Gesellschaft and the Alexander von Humboldt Foundation, will be presented to Alexandrova in a ceremony in Berlin in November 2022 (delayed one year because of COVID).

Alexandrova and her research team design new materials and develop new algorithms, guided by insights into electronic structure and chemical bonding, using a wide range of methods, including artificial intelligence and machine learning. She and her research team design new catalysts, building up from detailed understanding of their electronic structure, to the shapes, stability and catalytic properties.

She is being honored for her research in theoretical chemistry, in particular her studies on the catalysis of chemical reactions and materials science. Alexandrova has developed methods that simulate how a catalyst behaves during a chemical reaction, which structures mediate between the reaction partners in detail and how the reaction conditions — such as temperature, pressure and concentration of the starting materials — influence the states of the catalyst and this interaction states the press release announcing the medal.

“I am deeply honored to receive the Max Planck-Humboldt Medal,” said Alexandrova, a member of UCLA’s California NanoSystems Institute. “My laboratory is a warm home for students of many different backgrounds, from chemistry and biochemistry to physics, material science and engineering, computer science and applied mathematics.”

Alexandrova is the recipient of many awards and honors, including the American Chemical Society’s 2016 Rising Star Award, which recognizes exceptional women chemists on a national level; a J. William Fulbright U.S. Scholar grant; a 2020 Early Career Award in theoretical chemistry by the physical chemistry division of the American Chemical Society; a 2019 UCLA Distinguished Teaching Award and 2018 UCLA Undergraduate Research Faculty Mentor Award.

Terence Tao, UCLA professor of mathematics, has been selected by President Joe Biden as one 30 of America’s most-distinguished leaders in science and technology who will serve on his President’s Council of Advisors on Science and Technology.

A direct descendant of the scientific advisory committee established by President Eisenhower in 1957 in the weeks after the launch of Sputnik, the council is the sole body of external advisers charged with making science, technology and innovation policy recommendations to the president and the White House to address the country’s most pressing challenges.

Tao, who holds the James and Carol Collins Chair in the UCLA College, became the first mathematics professor in UCLA history to be awarded the Fields Medal in 2006, often described as the “Nobel Prize in mathematics.” He has earned many other honors, including the National Science Foundation’s Alan T. Waterman Award, the Breakthrough Prize in Mathematics, Royal Society’s 2014 Royal Medal for physical sciences, the Royal Swedish Academy of Sciences’ Crafoord Prize and the first Riemann Prize in Mathematics, established by Italy’s Riemann International School of Mathematics. National Geographic magazine featured him in its “What makes a genius?” May 2017 issue.

The new council includes two Nobel laureates, 20 elected members of the National Academies of Sciences, Engineering and Medicine, five MacArthur Foundation Fellows and two former cabinet secretaries.

The council advises the president “on matters involving policy affecting science, technology, and innovation, as well as on matters involving scientific and technological information that is needed to inform public policy relating to the economy, worker empowerment, education, energy, the environment, public health, national and homeland security, racial equity, and other topics,” the White House said.

‘Surfing’ particles: Physicists solve a mystery surrounding aurora borealis

The spectacularly colorful aurora borealis — or northern lights — that fills the sky in high-latitude regions has fascinated people for thousands of years. Now, a team of scientists has resolved one of the final mysteries surrounding its origin.

Scientists know that electrons and other energized particles that emanate from the sun as part of the “solar wind” speed down Earth’s magnetic field lines and into the upper atmosphere, where they collide with oxygen and nitrogen molecules, kicking them into an excited state. These molecules then relax by emitting light, producing the beautiful green and red hues of the aurora.

What has not been well understood is precisely how groups of electrons accelerate through the magnetic field on the last leg of their journey, reaching speeds of up to 45 million mph. In a study published today in the journal Nature Communications, that question is answered by physicists from UCLA, Wheaton College, the University of Iowa and the Space Science Institute.

A popular theory has been that electrons hitch a ride on Alfvén waves — a type of electromagnetic wave that spacecraft have frequently identified traveling Earthward along magnetic field lines above auroras. While space-based research has provided strong support for the theory, limitations inherent to spacecraft measurements have prevented a definitive test.

To overcome these limitations, the physicists conducted laboratory experiments on the Large Plasma Device at UCLA’s Basic Plasma Science Facility, a national collaborative research site supported jointly by the U.S. Department of Energy and National Science Foundation.

After reproducing conditions that mimicked those in Earth’s auroral magnetosphere, the team used specially designed instruments to launch Alfvén waves down the plasma device’s 20-meter–long chamber. Because Alfvén waves are thought to collect only a small portion of electrons in the plasma of space, the physicists focused on determining whether there were electrons that appeared to be traveling at a rate comparable to the electric field of the waves.

“This challenging experiment required a measurement of the very small population of electrons moving down the chamber at nearly the same speed as the Alfvén waves, numbering less than one in a thousand of the electrons in the plasma,” said Troy Carter, a professor of physics and director of the UCLA Plasma Science and Technology Institute.

“Measurements revealed this small population of electrons undergoes ‘resonant acceleration’ by the Alfvén wave’s electric field, similar to a surfer catching a wave and being continually accelerated as the surfer moves along with the wave,” said Gregory Howes, an associate professor of physics at the University of Iowa.

Electrons surfing on Alfvén waves (yellow) streaming toward Earth collide with nitrogen and oxygen molecules (white); in upper altitudes, these collisions result in the emission of red light, while in lower altitudes the emitted light is green.

Howes noted that these Alfvén waves appear following geomagnetic storms, space-based phenomena triggered by violent events on the sun, such as solar flares and coronal mass ejections. These storms can cause what is known as “magnetic reconnection” in the Earth’s magnetic field, in which magnetic field lines are stretched like rubber bands, snap and then reconnect. These shifts launch Alfvén waves along the lines toward Earth.

And because regions of magnetic reconnection shift during a storm, the Alfvén waves — and their accompanying surfing electrons — travel along different field lines over that time period, ultimately leading to the shimmering glow of the aurora’s curtains of light, Carter said.

In physics, electrons surfing on the electric field of a wave is a phenomenon known as Landau damping, in which the energy of the wave is transferred to the accelerated particles. As part of their research, the team used an innovative analysis technique that combined measurements of the Alfvén waves’ electric field and the electrons to generate a unique signature of the electron acceleration by Landau damping. Through numerical simulations and mathematical modeling, the researchers demonstrated that the signature of acceleration measured in the experiment agreed with the predicted signature for Landau damping.

The agreement of experiment, simulation and modeling provides the first direct test showing that Alfvén waves can produce accelerated electrons that cause the aurora, Carter said.

“This experimental confirmation of the physics behind the aurora is due to persistent ingenuity of research groups at the University of Iowa and UCLA,” said Vyacheslav (Slava) Lukin, program director for Plasma Physics at the National Science Foundation, who was not involved in the research. “From student support via an NSF Graduate Research Fellowship, to the NSF CAREER program for early career faculty, to the 25-year partnership between NSF and the Department of Energy that has enabled the unique capabilities of the Basic Plasma Science Facility, this is a success story of a discovery made possible by consistent support of the university research community.”

In addition to Howes and Carter, study authors included James Schroeder of Wheaton College, Craig Kletzing and Frederick Skiff of the University of Iowa, Stephen Vincena of UCLA, and Seth Dorfman of the Space Science Institute.

Graduating senior forged new connections to Vietnamese heritage through UCLA class

Anne Nguyen started observing the economic and emotional tolls of the pandemic before a lot of others.

Having grown up in a community of mostly Vietnamese immigrants, she knew families who owned nail salons, people who worked as nail techs and also was familiar with some of the health concerns given the exposure to chemicals in that industry. It wasn’t until she came to UCLA in 2017 that she realized the severity of some of the health problems associated with spending hours in a salon.

Then in March 2020, nail salon workers were being laid off even before shutdown orders because of the rapid decline in business after false reports that the virus was spreading in nail salons. Soon after there was the rise in anti-Asian racism.

“The impact on this community feels close to home,” said Nguyen, a soon-to-be UCLA graduate from San Jose, California, who is determined to help the broader immigrant community that raised her.

During her time at UCLA, Nguyen spent four years volunteering with the student-run Vietnamese Community Health organization, or VCH, which operates mostly in Orange County offering screenings for hypertension, blood glucose, cholesterol, as well as women’s health services like mammograms or OB-GYN consultations.

Nguyen and the group have also focused on offering connections to mental health providers who speak Vietnamese. She says the community, especially the elderly members, have historically stigmatized the use of mental health resources, but that these resources are invaluable to refugees and immigrants who are adjusting to a foreign culture and experiences.

“I think that my work with VCH was particularly meaningful to me because it introduced me to community-based medicine,” said Nguyen, who is on track to earn her bachelor’s degree in biochemistry and a minor in Asian American studies. “I loved the focus that the organization had on educating their patients, as well as treating/screening them. It really helped me establish my service philosophy of giving communities the tools they need to commit to long-term change themselves.”

This past winter quarter, Nguyen’s desire to help Asian immigrants, took a more academic turn. She enrolled in a course put on by the Asian American studies department and the UCLA Center for Community Engagement called “Power to the People: Asian American Studies 140XP.”

The Center for Community Engagement supports community-engaged research, teaching and learning in partnership with communities and organizations throughout Los Angeles and beyond. This particular course was borne out of the hunger strike at San Francisco States University in the 60s, during which students demanded the school offer ethnic studies classes and that the school diversify its faculty and student body. This course, which has been taught at UCLA for seven years exposes students to different Asian American and Pacific Islander communities in greater Los Angeles and creates opportunities to work directly with those organizations.

During the course, Nguyen met with the instructor and her classmates two hours each week to discuss history and theory, and met virtually with community organizers, advocates and members of the nail salon industry through the California Healthy Nail Salon Collaborative. The statewide, grassroots organization addresses health care, environmental factors, reproductive justice, and other social issues faced by low-income, immigrant and refugee women from Vietnam.

Dung Nguyen, program and outreach manager for the collaborative, supervised Anne Nguyen (no relation) and previous UCLA students who interned at the organization. Dung said there is nothing like working directly for an organization to bring social activism to life.

“Our student interns often reflect how civic engagement, advocacy, community organizations and collective power in a text book are very different than seeing this all play out in reality,” Dung Nguyen said.

Nguyen and another student phone banked to raise awareness about two bills in the state legislature — assembly bills 15 and 16, which were intended to protect tenants from being evicted during the pandemic and beyond. The pair created packages of Lunar New Year cards and masks for members of the nail salon collaborative to reinforce social bonds with the group during the isolation of the pandemic. They ran a small fundraiser to support nail salon workers who lost income during the pandemic and couldn’t meet their most basic needs. They also conducted a survey to see which members had been vaccinated, and then helped women get vaccination appointments so they could return to work safely.

“I did not expect to take a class like this when I came to UCLA since I never thought of volunteering/interning as something you can structure into a curriculum,” Nguyen said. “Every organization had a different method of organizing to best fit their communities and this class really reinforced that this was valid. The class gave me a greater appreciation for all the thought that went into the creation and continuation of the nail salon collaborative and all of the other class partners.”

Community organizer and course lecturer Sophia Cheng said that all the community partners tend to see themselves as part of the ethnic studies movement that started in the 1960s.

Cheng, who is the primary liaison for all the organizations, pushes students to go beyond critiquing, analyzing and dissecting situations, instead asking them to come up with real solutions to real issues. She said that she’s not trying to train every student to join the non-profit sector; there aren’t enough jobs in the Asian American nonprofit sector. Instead, Cheng focuses on different ways students can serve their communities in whatever career path they take.

Nguyen’s trajectory continues to be influenced by Cheng’s approach.

“I want to be a doctor, and I am focused on community health,” Nguyen said. “The course taught me to be more cognizant of cultural fit when it comes to health care, and other needs. A lot of Asian American and Pacific Islander patients might not trust or have resources like in typical western health care. The older generation also might not trust the younger generation. I’m using approaches from class to figure out how to approach medicine and how to help people, from the place where they are. I try to figure out what are the needs of the people, how can I serve them, and help them strengthen what they have to improve themselves.”

New Insights into Mars and Venus

 

By Christopher Crockett and Stuart Wolpert

 

David Paige is deputy principal investigator of Radar Imager for Mars’ Subsurface Experiment, or RIMFAX, one of seven instruments on NASA’s Perseverance rover.

About the size of a car, the Perseverance rover landed on Mars on Feb. 18. Over the next two years it will explore Jezero Crater in Mars’ northern hemisphere for signs of ancient life and new clues about the planet’s climate and geology.

Among other tasks, Perseverance will collect rock and soil samples in tubes that a later spacecraft will bring back to Earth. The experiments will lay the groundwork for future human and robotic exploration of Mars. RIMFAX will probe beneath the planet’s surface to study its geology in detail.

“Jezero Crater is a very interesting location on Mars because it looks like there was once a lake inside the crater, and that a river flowed into the lake and deposited sediments in a delta,” Paige said. “We plan to explore the delta to learn more about Mars’ climate history, and maybe something about ancient Martian life. What we’ll be able to see once we start roving and what we will actually learn is anybody’s guess.”

RIMFAX will provide a highly detailed view of subsurface structures and help find clues to past environments on Mars, including those that may have provided the conditions necessary for sup-porting life, he said.

Paige emphasized that RIMFAX is an experiment. “We’ve never tried using a ground-penetrating radar on Mars before, so we can’t really predict what types of subsurface structures we might be able to see. But we have done some fairly extensive field testing of RIMFAX on Earth to learn how to use it and how to interpret the data. Here, ground-penetrating radars can be very useful for clarifying subsurface geology.”

Is he hopeful of finding water, or evidence of water, beneath the planet’s surface?

“There are all kinds of evidence for past liquid water all over Mars,” Paige said. “At Jezero, there must have been a lot of water at some point, but we don’t expect that the ground beneath the rover will still be wet. Mars today is a very cold place, and any water in the shallow subsurface should be frozen at Jezero. What we’re interested in finding are geologic features that wouldn’t be expected to form under present climatic conditions, as those would be especially interesting targets to search for signs of past life.”

UCLA College graduate students Max Parks and Tyler Powell in Earth, Planetary, and Space Sciences are part of the science team, and Mark Nasielski, a UCLA graduate student in electrical engineering, is part of the operations team.

VENUS IS AN ENIGMA

Venus is the planet next door 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 — findings published in the journal Nature Astronomy.

“Venus is our sister planet, and yet these fundamental properties have remained unknown,” said professor Jean-Luc Margot, who led the research.

Earth and Venus have a lot in common: Both are rocky planets and 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 spins, any future landing attempts could be off by as much as 30 kilometers.

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.

Venus’ heavy atmosphere is likely to blame for the variation.

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 top. On Earth, this “precession” takes about 26,000 years to cycle around once. Venus needs a little longer: about 29,000 years.

The team has turned its sights on Jupiter’s moons Europa and Ganymede. Many researchers strongly suspect that Europa 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 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.

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.

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.
