Perspective Article on ENLACE Program in ACS Omega: Building Compassion and Human Bridges through Research Collaborations
January 2022
Our ENLACE binational summer research program was established with the aim of encouraging the participation of high school and college students in research in the sciences and engineering, while promoting cross-border friendships between the United States and Mexico. The program unites students around science and engineering questions and concurrently engages them in a rich curriculum that promotes understanding of broader societal issues of equity, inclusion, tolerance, and social justice. Because we built our program around hope and cooperation, it is our aspiration and promise that walls and borders─all kinds of walls and borders─can be eradicated through kindness, compassion, and respect for others. ENLACE is not just a program we organize every summer, it is also a program that defines who we are as people and the kind of contribution we want to make in the world.

The Earth and Moon are like identical twins, made up of the exact same materials -- which is really strange, since no other celestial bodies we know of share this kind of chemical relationship. What's responsible for this special connection? Looking for an answer, planetary scientist and MacArthur "Genius" Sarah T. Stewart discovered a new kind of astronomical object -- a synestia -- and a new way to solve the mystery of the Moon's origin.

The UC Santa Cruz team published an article describing wave patterns created within Saturn's rings by the planet's internal vibrations. They explain that Saturn's distinctive rings were observed in unprecedented detail by NASA's Cassini spacecraft, and scientists have now used those observations to probe the interior of the giant planet and obtain the first precise determination of its rotation rate. The length of a day on Saturn, according to their calculations, is 10 hours 33 minutes and 38 seconds. Their findings were also highlighted in a UC News Letter. Read more.

A team led by Center for Energy Research scientists Chris McGuffey, Joohwan Kim, and Prof. Farhat Beg have shown that proton beams, which are well-studied products of intense lasers, can locally heat a gold sample to over 35 eV, or 400,000 degrees. But, surprisingly, the heating strongly depended on what material was in front of the gold, suggesting that the energy lost by the beam in the hot materials is far different from what existing cold models predict. The experiment was carried out at the National Nuclear Security Administration’s Trident Laser at Los Alamos National Laboratory with collaborators at Trident, Lawrence Livermore National Laboratory, General Atomics, the University of Alberta, and the Ohio State University. The work is described in an article published today in Nature’s online journal Scientific Reports.
Four researchers at the Jacobs School of Engineering at UC San Diego have been named Fellows of the American Association for the Advancement of Science (AAAS), the largest general science organization in the United States and publisher of the journal Science.
Farhat Beg, Rajesh Gupta, Pavel Pevzner and Liangfang Zhang join a total of 416 AAAS members that have been awarded this honor because of their scientifically or socially distinguished efforts to advance science or its applications. New Fellows will recognized during a ceremony Saturday, Feb. 16, from 8 to 10 a.m. Eastern Time at the AAAS Fellows Forum during the 2019 AAAS Annual Meeting in Washington, D.C. This year’s AAAS Fellows also will be formally announced in the AAAS News & Notes section of the journal Science Nov. 29, 2018.
WASHINGTON, D.C. – The U.S. Department of Energy’s National Nuclear Security Administration (DOE/NNSA) has designated four new Centers of Excellence at universities across the nation as part of the Stewardship Science Academic Alliances (SSAA) Program.
The four new centers bring the total number of SSAA Centers of Excellence to eight. The centers enrich graduate education and training while also facilitating interactions between NNSA National Laboratory scientists and emerging leaders in academia.
“These cooperative agreements strengthen the Nuclear Security Enterprise by advancing areas of science relevant to the stockpile stewardship mission and ensuring a pipeline of future scientists to carry out that mission,” said Dr. Kathleen Alexander, Assistant Deputy Administrator for Research, Development, Test and Evaluation in NNSA’s Office of Defense Programs.
The University of California San Diego will receive $10.5 million over 5 years to manage the Center for Matter under Extreme Conditions. Dr. Farhat Beg will lead research and technological breakthroughs in high-energy density physics while training graduate students at the participating campuses and NNSA National Laboratories. The work will have an emphasis on creation and diagnosis of extreme states of matter—both magnetized and unmagnetized—utilizing computer modeling and experiments to develop a better understanding of high-energy density systems.
Sarah Stewart is a planetary scientist shedding light on planet formation and evolution. Through a combination of shock physics experiments on natural materials (such as ice and rock), theoretical models, and computational simulations, Stewart investigates the effects of high-energy impacts onto planets and planet-like bodies. For example, using ice impact experiments, she demonstrated that the presence of subsurface ice significantly and predictably affects the shape of an impact crater, such that the shapes of craters on planets such as Mars can reveal much about their subsurface composition.
Most notably, Stewart has advanced a novel explanation for how the Moon was formed. It had been widely accepted that the moon was formed from the debris of an object that collided with the proto-Earth. Recent geochemical studies, however, show that the chemical composition of the Moon is very similar to that of the Earth—that is, the Moon is made up primarily of terrestrial materials rather than materials from the impacting celestial body. Stewart and her colleagues have discovered an entirely new astrophysical object, called a synestia, in seeking to resolve this discrepancy. A synestia is a donut-shaped cloud of vaporized and molten rock produced when two objects collide in a high-energy, high-angular momentum impact. The Earth and Moon both formed from one large synestia, produced by such a collision, cooled and condensed. The synestia theory could explain both the similarity in the elemental and chemical compositions of the Earth and Moon as well as heretofore unexplained features in the Moon’s orbit.
The synestia structure could be a common outcome of collisions during planetary growth and thus hold broader implications for understanding the evolution of other planets. With the ever-growing number of exoplanet discoveries and missions to other planets, Stewart will play a critical role in providing a firmer and more comprehensive basis for understanding planet formation and the resulting physical, geological, and geochemical features of planets.
