Scientists at NNSA facilities study climate and meteorology. Other sites are key players in weather preparedness.

Today, on National Weatherperson Day, NNSA recognizes numerous contributions to the nation’s climate and weather readiness in any situation. With emergency response as one of its core missions, NNSA’s enterprise helps prepare the nation against the worst disasters, with weather as an important component in the equation of security.

NNSA’s labs have been recognized internationally for their invaluable work in climate modeling and aid in emergency weather preparedness. NNSA’s Los Alamos and Sandia National Laboratories are active as Weather-Ready Nation (WRN) Ambassadors for the National Oceanic and Atmospheric Administration’s (NOAA) effort to strengthen national resilience against extreme weather.

NNSA’s Pantex Plant has been recognized as one of the National Weather Service’s StormReady sites for its community activism in severe weather preparedness. Staff at NNSA’s Los Alamos Laboratory received the GreenGov Presidential Award in November 2015 for their proactive commitment to environmental stewardship through planning, monitoring, and response.

Three of NNSA’s labs, Sandia, Lawrence Livermore, and Los Alamos, work in a partnership with other labs and groups to generate the most complete climate and Earth system models for climate change issues. Lawrence Livermore and Sandia each have a dedicated organization for monitoring and studying climate, while Los Alamos has two (here and here).

NNSA’s meteorological expertise also plays a big role in the nation’s preparedness against nuclear threats via the National Atmospheric Release Advisory Center (NARAC), which conducts atmospheric dispersion modeling of hazardous materials in support of health and safety decision making. NARAC is also a key stakeholder in the Interagency Modeling and Atmospheric Assessment Center. With support from across the nuclear security enterprise, NNSA’s emergency response assets are integrated into the Federal Radiological Monitoring and Assessment Center to keep the nation safe in case of radioactive threats by, among other activities, evaluating weather conditions. 

Many dedicated men and women of NNSA’s enterprise are expert weatherpersons as part of their jobs in national security, using highly specialized technology for accurate data-gathering and collaborating with other experts and the public in educational and emergency outreach.

World Cancer Day encourages citizens worldwide to take action, raise awareness, and garner support in the campaign to end cancer. Inherent in NNSA’s missions are technological developments for detection, computation, and chemistry—with benefits for cancer research.

Scientists at NNSA’s laboratories receive both federal and private recognition for their work that has a huge impact on cancer research. One exceptional young scientist received an award from NIH for her computational work to learn more about how cancer progresses. Both Sandia National Laboratories and Lawrence Livermore National Laboratory partner with universities to expand cancer research capabilities.

Cancer breakthroughs at NNSA labs include uncovering how a protein stops prostate cancer metastasis to bone, an association between a virus and bladder cancer, production of medical isotopes that fight cancer, a drug to destroy childhood acute lymphoblastic leukemia, use of nanoparticles to destroy cancerous cells, and development of a high-resolution gamma camera used for prostate cancer detection.

NNSA’s work in nonproliferation has led to development of very sensitive and often non-invasive monitoring and detection technologies that have applications in cancer detection and treatment. NNSA retrained nuclear weapons scientists internationally to work in cancer treatment. A recently developed laser plasma accelerator can be used in scanning devices to spot hidden nuclear materials and for radiotherapy treatments for cancer.

Participants in Apex Gold at Lawrence Livermore National Laboratory.

What would national leaders do in the face of a transnational nuclear terrorism threat? Last week, ministers and other senior delegates from 37 nations, along with representatives from the International Atomic Energy Agency, the European Union and the United Nations gathered in Livermore, California, to practice their ability to respond effectively to an emerging nuclear security threat. 

On Jan. 28, the U.S. Department of Energy and the Kingdom of the Netherlands Ministry of Foreign Affairs hosted Apex Gold, the first ever minister-level gathering to identify national and international actions to address a nuclear crisis. The ministers were presented with a hypothetical nuclear terrorism scenario and then worked together to determine how each of their nations might respond at each step of the situation. The participants also toured Lawrence Livermore National Laboratory to better understand some of the technical tools available for detecting and analyzing nuclear material and making decisions in the event of a nuclear terrorism crisis.

Apex Gold helped to prepare ministers to advise their heads of government during a nuclear security crisis or emergency. The exercise also laid important ground work for the 2016 Nuclear Security Summit, which President Obama will host on March 30 – April 1, 2016 in Washington, D.C. At the Summit, global leaders will discuss the threat of nuclear terrorism and identify steps to minimize the use of civil highly-enriched uranium, secure nuclear materials, and counter nuclear smuggling. They will also discuss how the vital work the Nuclear Security Summit process can be carried forward in the future.

These high performance computing (HPC) simulations of star formation account for a broad range of physical processes, including: gravity, supersonic turbulence, hydrodynamics, outflows, magnetic fields, chemistry and ionizing and non-ionizing radiation.

High performance computing (HPC) simulations exploring star formation by Lawrence Livermore astrophysicist Richard Klein were among select research highlights featured by NASA at the recent supercomputing conference in Austin, Texas.

Klein’s “Simulating Star Formation: From Giant Molecular Clouds to Protostellar Clusters” presentation is now on NASA’s website.

The origin of star clusters remains one of astrophysics’ fundamental unsolved problems. Stellar cluster and massive star formation are at the center of the complex processes that shaped the universe as we know it today. Yet a clear understanding of the processes involved in star formation remains elusive.

Taking on such a problem requires complex simulations that must include a broad range of physical processes, including: gravity, supersonic turbulence, hydrodynamics, outflows, magnetic fields, chemistry and ionizing and non-ionizing radiation. But such simulations are very difficult to produce because of the high degree of non-linear coupling and feedback mechanisms among these processes, as well as the large dynamic range in time and spatial scales.

Users discovered items the device could magnify, such as yarn, human hair, and flower petals.

Employees lunching on Friday, January 15, in the Department of Energy headquarters cafeteria received smartphone microscopes and a mission: Engage five students over Martin Luther King Jr. Day of Service in a STEM conversation using the device.

Employees from the DOE Office of Economic Impact and Diversity, including Director Dot Harris and fellow Melinda Higgins, recruited employees from many offices to participate in the STEM outreach event training.

“The broad participation goes to show how people from all areas can work to increase STEM literacy and awareness,” Higgins said.

“This is a great way to show innovative technology, using an existing technology such as the camera on your smartphone and improving and creating something new such as the microscope,” Higgins said. “This one device can be used to explain the physics behind light and microscopy, the structure and patterns of different substances on a microscopic level as well as the ability to analyze data that is collected to study as images.”

Participants in the STEM outreach event demonstrated using the microscope with grains of salt, tape, and flower petals. The clip-on device magnifies items 100x.

“I can tell you right now my kids are going to be looking at a lot of bugs on this thing,” said one employee, who said she was excited to share the device with her daughters.

Higgins and her colleagues encouraged microscope recipients share the micro-images they took on social media using #microSTEM. The design of the microscope is open-source so anyone can make one. Learn more and watch a video about the microscopes, where they come from, and how they're made here.

Sandia National Laboratories' Juan Elizondo-Decanini turned a long-standing problem into an idea he believes could lead to better and less expensive machines, from cell phones to pressure sensors.

“This is one of those cases where it appears it’s going to result in substantial savings and it’s going to generate a whole suite of new gadgets,” he says.

Juan leads a project on nonlinear behavior in materials — behavior that’s usually shunned as too unpredictable. Instead of avoiding nonlinearity, he’s embracing it using harmonic waves called solitons and studying, for example, how nonlinearity might be used in capacitors to further improve cell phone reception or lock out computer hackers.

Capacitors are fundamental elements in electronic circuits that store energy by accumulating electrical charge after voltage is applied to them. The stored charge is determined by the capacitance value: the more capacitance, the more charge stored and the more energy at a given “charge” voltage. High-quality capacitors are considered linear because capacitance value doesn’t change as voltage is applied to store a charge. In a nonlinear capacitor, capacitance value changes as voltage is applied, so the energy or stored charge is different from what was expected.
