State of WMD: How 9/11 impacted the mission of national security laboratories

In 2001, Los Alamos National Laboratory was several years into the stockpile stewardship program – developing physics and computational tools to ensure the safety and reliability of the nation’s nuclear weapons in the absence of testing. We weren’t sure what the future held. While we knew that nuclear weapons were still an important part of the nation’s military and diplomatic strategy, the end of the Cold War meant that the role they would play in national defense policy was unclear.

 

After September 11, the reality that not only did threats still exist but they could easily land on our shores hit hard. Soon after, a renewed sense of urgency emerged around the need to secure our nuclear weapons and ensure their readiness at a moment’s notice. On the top of many minds at Los Alamos were the what-if questions, specifically: What if the terrorists had used an improvised nuclear device? What if they might still? Could they potentially get a hold of a nation-state’s weapon of mass destruction? What about the potential for bio-attacks? (Full Story)

 



Los Alamos National Lab works on hydrogen-powered trucks

 

Recent data estimates diesel-powered trucks spew more than 200 tons of CO2 into the air every year. That's why Los Alamos National Lab is working on a new project to replace the diesel-powered trucks – with hydrogen-powered ones.

 

"As you try to get all of the carbon out of transportation infrastructure, you gotta do both light-duty vehicles, and heavy-duty vehicles,” said Rob Borup, a researcher at Los Alamos National Lab. Hydrogen-powered vehicles are --by definition-- an electric vehicle -- but there's no battery inside. Instead-- they use a fuel cell to combine hydrogen gas with oxygen to make electricity.

few years ago, Morgan Gorris, an Earth systems scientist at Los Alamos National Laboratory in New Mexico, decided to investigate an important question: What makes a place hospitable to Cocci? She soon discovered that the fungus thrives in a set of specific conditions. U.S. counties that are endemic to Valley fever have an average annual temperature above 50 degrees Fahrenheit and get under 600 millimeters of rain a year. 

 

“Essentially, they were hot and dry counties,” Gorris told Grist. She stuck the geographic areas that met those parameters on a map and overlaid them with CDC estimates on where Cocci grows. Sure enough, the counties, which stretch from West Texas through the Southwest and up into California (with a small patch in Washington State) matched up. (Full Story)

Mars rover grabs first rock sample, a major step in hunt for alien life

This small cylinder of rock—shown here within the rover’s drill rig—is the first sample of dozens, NASA image.

 

"We are going to be surprised," says Nina Lanza, a planetary scientist and team lead for Space and Planetary Exploration at Los Alamos National Laboratory. "We are going to learn things that we never could have imagined."

 

The sampled boulder appears similar to other rocks poking up from the crater floor, sometimes called "high-standing rocks," says Roger Wiens, a planetary scientist at Los Alamos National Laboratory and principal investigator of Perseverance's SuperCam. Early on, the team planned to sample one of these high-standing rocks as well as the paver stones. “But we wanted to start with what we thought would be the easiest, which would be the softer ones—and, uh, oops,” Wiens laughs.

epigenetics in 2018.  From TED. 

 

When Karissa Sanbonmatsu joined the Los Alamos National Laboratory (LANL) as a postdoctoral researcher in 1997, she was eager to apply her plasma physics training to problems in space physics and laser fusion. Shortly after becoming a principal investigator, however, she became intrigued by the life sciences and decided to shift to studying biophysics. “I made it happen by leveraging transferable skill sets,” she says. Now she enjoys success as a structural biologist, combining wet lab biochemistry with computational biophysics and cryoelectron microscopy. “When you switch fields, you bring a fresh perspective that people haven’t heard about before,” she says.

Answering The Call: How New Mexico’s national laboratories used science and technology after 9/11 to help keep the country safe

The terrorist attacks of September 11, 2001, changed all of us in ways big and small — from our sense of security to how we travel. For New Mexico’s two national security laboratories, it meant quickly pivoting our scientific, engineering and technological resources to respond. As we reflect on the 20th anniversary, we’re reminded of the continuing need to be ready and equipped to counter the evolving threats that face our nation.

 

Los Alamos and Sandia National Laboratories had already been doing important work for the U.S. government to keep Americans safe when the Twin Towers and Pentagon were attacked 20 years ago. But it became immediately clear that, in addition to the innovation needed to protect the country from attacks by adversarial nations with defined borders, we must also develop tools to protect Americans from attacks by terrorist groups who operated in multiple countries and were driven by many agendas.

Diesel engines have been the norm for heavy-duty long-haul trucks since the mid-20th century. But the black smoke belching from the big rigs has become a growing concern as research shows diesel pollution is bad both for public health and the warming climate.

 

Some Los Alamos National Laboratory researchers are working on a technology to clear this noxious pollutant from the roadways. The lab is part of a consortium working to develop hydrogen fuel cells that would work well on big trucks and eventually replace the diesel-burning engines.

 

“Really, the time to get [hydrogen fuel] trucks out on the road is now,” said Rod Borup, lab scientist and fuel cell program manager. (Full Story)

With a goal of refining and calibrating computer models for wildfire and climate, we are studying pyrocumulonimbus clouds from the B.C. and Australia fires at several scales, from the molecules in the hot gases of a fire, to how the blaze moves across a specific landscape, to how smoke evolves in the atmosphere, and finally to how smoke travels around the glove. Our work also includes laboratory experiments and field observations about smoke gathered by our Center of Aerosol-gas Forensic Experiments (CAFÉ), where we study black-carbon emissions and their mixing with organic gases from fire.

Plenty of evidence for recombination in SARS-CoV-2

 

Early on in the pandemic, research suggested recombination likely played a pivotal role in SARS-CoV-2’s emergence as a human pathogen. In a study published in July 2020, for instance, Bette Korber, a researcher at Los Alamos National Laboratory, and colleagues reported that a portion of the receptor binding domain of SARS-CoV-2’s spike protein—the part of the spike that directly interacts with the ACE2 receptor that the virus uses to gain entry into cells—came from recombination with pangolin coronaviruses.

 

It’s no surprise, then, that the virus continued to recombine after it began infecting people. “It should be happening because it’s a very important evolutionary mechanism for these viruses,” explains Korber. At the same time, she adds, “quantifying how much it’s there can be tricky because . . . it’s computationally not easy to look at vast data sets,” and the search can be confounded by genetic changes that can come about in the lab.

Predicting mosquito populations before a surge

 

At Los Alamos National Laboratory, we’re studying mosquito populations to understand how they grow, how they change with the seasons and, in particular, how they spread infectious diseases to humans and other animals. The goal is to create a computer-based model that will accurately simulate mosquito populations based on data about precipitation, temperature, water levels and other environmental factors in a given area, so people will know ahead of time about an increased risk of disease transmission.

 

For this project, we’re looking specifically at West Nile virus, which birds transmit to humans via mosquitoes. We analyzed 15 years of data from several different locations in the United States and Canada, making it one of the largest modeling studies of mosquito populations over time ever conducted. Previous studies have looked at temperature and precipitation, but this is the first to use stream. (Full Story)

Complex carbon-based molecules are everywhere in the Cosmos.  How many of these molecules are formed is still something of a mystery, particularly for carbon molecules formed by nature on primordial Earth that gave rise to life on this planet.

 

Researchers at Los Alamos National Laboratory, using a laser-driven compression technique and x-ray diffraction interrogation at the Stanford Linear Accelerator (SLAC) facility in California, have recently discovered a mechanism for the formation of complex carbon sheet-shaped solid molecules in liquid benzene, a common hydrocarbon, that could unravel some of the carbon formation mystery.
