As world leaders gathered for the United Nations General Assembly, Washington
Post Live explored the course of climate change across all seven continents,
one at a time.
From melting Antarctic glaciers to deforestation of the Amazon to green
innovation globally, they put a spotlight on environmental challenges, the
lessons learned for humanity and the bold solutions for new pathways.
LLNL Director Kim Budil joined Tim Latimer, CEO and co-founder of Fervo
Energy, and Mateo Jaramillo, CEO of Form Energy, along with moderator Zachary
Goldfarb, Washington Post’s Climate & Environment Editor, for the panel
“North America: Energy Moonshots.”

Researchers at Lawrence Livermore National Laboratory (LLNL), in
collaboration with the Georgia Institute of Technology, have made a
significant breakthrough in understanding the impact of carbon dioxide (CO2)
on the stability of amine-functionalized porous solid materials, a crucial
component in direct air capture (DAC) carbon-capture technologies.
This new research, published https://pubs.acs.org/doi/10.1021/jacs.4c08126 in
the /Journal of the American Chemical Society/ and featured on the journal
cover, sheds light on the complex interactions
https://phys.org/tags/complex+interactions/ between CO2 and
poly(ethylenimine) sorbents, offering important insights that could enhance
the efficiency and durability of DAC systems.

… Saving the planet
https://www.extremetech.com/science/we-might-be-able-to-nuke-asteroids-to-save-earth-after-all
Earth exists in a cosmic shooting gallery, and it’s not a matter of if but
rather when a large asteroid hits the bullseye. It’s happened plenty of times
in the past, but for the first time, humanity might have a chance to avert
disaster. The movies always say we can nuke asteroids, an option long
dismissed by scientists as fantasy. A new study says that might not be as
crazy as it sounds.
We’ve learned more about the composition of asteroids in the last few years
than in the prior few decades. Missions like Hayabusa2 and OSIRIS-REx have
returned pristine samples
https://www.extremetech.com/science/nasa-reveals-massive-osiris-rex-asteroid-sample
from ancient space rocks, and the DART mission successfully changed the orbit
of a small asteroid
https://www.extremetech.com/extreme/343489-nasa-dart-mission-proves-kinetic-impact-can-save-earth-from-incoming-asteroids.
However, scientists estimate it could take dozens of DART-like missions to
redirect a dangerous asteroid that was on course for Earth. As an
alternative, the Department of Energy’s Lawrence Livermore National
Laboratory (LLNL) suggests we could use nuclear weapons, but not like they do
in the movies.
The analysis from LLNL used the asteroid Bennu (above) as a model. OSIRIS-REx
gathered extensive data on this object before scooping up a sample to bring
home. LLNL found that a kinetic impactor like DART would be ineffective
against a pile of gravitationally bound rubble

like Bennu.

Agricultural and Mechanical University, spent their summer conducting
research at LLNL’s Jupiter Laser Facility. (/LLNL image/)
… Interns shine bright
This summer, the Jupiter Laser Facility
https://jlf.llnl.gov/?utm_source=miragenews&utm_medium=miragenews&utm_campaign=news
(JLF) hosted interns as part of the Reaching a New Science Energy Workforce
(RENEW) program – a DOE Office of Science initiative aimed at developing a
strong, diverse workforce pipeline through partnerships with minority serving
institutions.
The interns, Alexandra Koleva and Aliyah St Louis-Alleyne from Florida
Agricultural and Mechanical University (FAMU), were hosted by JLF director
Félicie Albert and mentored by Dean Rusby and Matt Selwood.
The mentors brought the interns onto their respective experiments, allowing
them to explore different uses of the Titan laser — a unique laser platform
combining high-energy pulses with long and extremely short pulse lengths.
“JLF is a user facility, and by pairing the interns with the experimental
teams led by Dean and Matt, we were able to offer them a unique experience
doing hands-on work and learning about lasers and high-energy-density
science,” Albert said.

… Celebrating Hispanic heritage
As we each celebrate National Hispanic Heritage Month in our own ways, here
is a classic American story of big dreams turning into reality.
This is the story of José Hernández, who grew up picking produce in the
fields of the San Joaquin Valley in California.
This is the story of migrant farm workers and how they allowed their kids to
dream big.
This is the story of how José Hernández become an engineer working at
Lawrence Livermore National Lab.
