… An innovative partnership
California State University Bakersfield has entered a new partnership with
the innovative and cutting-edge science and technology at Lawrence Livermore
National Laboratory (LLNL). The school hopes the partnership doesn’t just
impact the school, but also the county.
On Tuesday, the room was filled with applause as energy leaders, school
partners and others looked at a new partnership between CSU Bakersfield and
Bay Area-based lab, Lawrence Livermore. The budding partnership signals a
reflection of a new future for all of Kern County.
With state officials aiming to transition to carbon neutrality by 2045,
Lawrence Livermore conducted a report called “Getting to Neutral” in
2020, and found Bakersfield was a unique place of opportunity for
California’s clean energy transition. The partnership between the Lab and
CSUB will help further research on clean energy and what that could look like
here at home.
“A lot of the gas and oil infrastructure is perfect for carbon capture and
storage sites, and there is an opportunity here to build a new economy based
around carbon management,” said LLNL Director Kim Budil. “It’s not
about getting rid of oil and gas, but really about creating a stable
transition, from where the economy and where the community is today, to a
more sustainable future based on clean energy technology.”

… We’re talking physics with a phone
As efforts continue to try to get more students engaged in careers in
science, technology, engineering and math (STEM), one Bay Area scientist has
created a program, designed to break down barriers.
Lawrence Livermore National Laboratory scientist David Rakestraw has
developed, “Physics with Phones” over the past four years. The course,
designed for high school and college students, allows students to perform
more than 100 different physics experiments using their iPhones.
“Companies are putting hundreds of billions of dollars a year into making
this better and to have all these features in it,” Rakestraw said. “They can
now be used to teach students in a class.”
Rakestraw recently took his program on the road to a physics class at
Livermore High School. The students used their phones to measure concepts
like velocity, frequency and friction.

… He picked an actor with a familiar vibe
NASA astronaut José Hernández says only Michael Peña could have played him
in “A Million Miles Away,” the movie about his life.
And the reason is pretty simple: he had seen Peña wearing an orange space
suit just like his in 2015’s “The Martian.” / /
“I said, ‘He has experience already. He’s been an astronaut!’”
Hernández, 61, remembers telling writer-director Alejandra Márquez Abella
and producer of “A Million Miles Away” (in theaters and streaming).
“Luckily, they listened to me and they did contact Michael and he agreed to
Márquez Abella said “When you think about an astronaut, you never think
that he could be like your uncle.” The filmmakers had found in Peña an
actor who “looks like you, talks like you, or has just a familiar vibe.”
Hernández agrees there’s an everyday relatability to Pena.. “I’m
normal-looking,” he joked. “You don’t want an Antonio Banderas because
people won’t have empathy with that person.”

… Rare earths’ future hangs in the balance
The clean energy-driven rare earths imbalance may be creating a hidden
opportunity for technology and material scientists exploring new ways to
utilize special properties of the elements on the periodic table for the
betterment of modern living.
DOE has tackled the rare earth balance problem head-on by tasking its
national labs to find new uses for oversupplied rare earths.
Hunter Henderson, a materials engineer at Lawrence Livermore National
Laboratory, is leading a team seeking to correct the rare earth imbalance by
developing high-volume and high-value applications for cerium. This project
demonstrates that metal 3D printing of aluminum-rare earth element alloy
forms an internal nanostructure that is resistant to degradation. The team
found that this 3D-printed aluminum-cerium alloy outperformed the aluminum
currently used in aerospace and defense components. These alloys also
demonstrate enhanced thermal performance, which adds to their value and the
cerium that goes into them. The team will scale up for demonstration and
continue to improve performance at room temperature strength.
The Gordon Bell Prize for Climate Modeling submission details the Simple
Cloud Resolving E3SM Atmosphere Model (SCREAM) team’s record-setting
demonstration of SCREAM on Oak Ridge National Laboratory’s 1.2 exascale
… SCREAMing for a prize
A team from Lawrence Livermore National Laboratory (LLNL) and seven other
Department of Energy national laboratories is a finalist for the new
Association for Computing Machinery Gordon Bell Prize for Climate Modeling
for running an unprecedented high-resolution global atmosphere model on the
world’s first exascale supercomputer.
The Gordon Bell submission, led by Energy Exascale Earth System Model (E3SM)
chief computational scientist Mark Taylor, details the team’s
record-setting demonstration of the Simple Cloud Resolving E3SM Atmosphere
Model (SCREAM) on Oak Ridge National Laboratory’s 1.2 exaFLOP (1.2
quintillion computing operations per second) Frontier machine.
Incorporating state-of-the-art parameterizations for fluid dynamics,
microphysics, moist turbulence and radiation, SCREAM is a full-featured
atmospheric general circulation model developed for very fine-resolution
simulations on exascale machines. The effort is led by LLNL staff scientist
Peter Caldwell, who also heads the Lab’s Climate Modeling group.
