An international team of scientists has blazed a new trail for studying how atoms respond to radiation, by tracking the energetic movement of electrons when a sample of liquid water is blasted with X-rays.

The experiment, described in this week’s issue of the journal Science, required “freezing” the motion of the atoms with which the electrons were associated, on a scale of mere attoseconds. An attosecond is one-quintillionth of a second — or, expressed another way, a millionth of a trillionth of a second.

Attosecond-scale observations could provide scientists with new insights into how radiation exposure affects objects and people.

“What happens to an atom when it is struck by ionizing radiation, like an X-ray? Seeing the earliest stages of this process has long been a missing piece in understanding how radiation affects matter,” Xiaosong Li, a chemistry professor at the University of Washington and a laboratory fellow at the Pacific Northwest National Laboratory, said in a UW news release. “This new technique for the first time shows us that missing piece and opens the door to seeing the steps where so much complex — and interesting — chemistry occurs!”

Bringing artificial intelligence to bear on issues relating to nuclear weapons might sound like the stuff of a scary sci-fi movie — but at the Department of Energy’s Pacific Northwest National Laboratory, it’s just one of the items on the to-do list.

One of PNNL’s research priorities is to identify and combat complex threats to national security, and AI can help meet that priority by detecting attempts to acquire nuclear weapons or associated technology.

Nuclear proliferation detection is one of the potential applications that could get an assist from the Center for AI @PNNL, a newly announced effort to coordinate research that makes use of AI tools — including the generative AI tools that have captured the attention of the tech world over the past year or two.

“For decades we’ve been doing artificial intelligence,” center director Court Corley, PNNL’s chief scientist for AI, told me in a recent interview. “What we’re seeing now, though, is an exceptional phase shift in where AI is being used and how it’s being used.”

The Department of Energy’s Pacific Northwest National Laboratory is shining a brighter spotlight on artificial intelligence by creating the Center for AI @PNNL, but don’t expect the lab’s researchers to build a better chatbot.

Instead, the center is meant to advance AI applications that boost PNNL’s capabilities in its traditional focus areas, including scientific discovery, national security and energy resilience.

“The creation of the Center for AI @PNNL will leverage and amplify these capabilities for even greater impact in service of our nation,” PNNL Director Steven Ashby said today in a news release.

Today’s announcement coincides with the annual Conference on Neural Information Processing Systems, or NeurIPS, which is taking place this week in New Orleans. The center’s creation serves as further evidence that AI tools are rapidly transforming a wide range of scientific and technical fields.

“The time is right for PNNL to focus its AI-related efforts,” said Court Corley, PNNL’s chief scientist for AI and director of the new center. “The field is moving at light speed, and we need to move quickly to keep PNNL at the frontier.”

Zeno Power says it has successfully completed its first demonstration of a new type of radioisotope heat source that could be used to generate off-grid power in settings ranging from the bottom of the ocean to the surface of the moon.

The demonstration — performed at Pacific Northwest National Laboratory in Richland, Wash. — took advantage of the energy provided by the radioactive decay of strontium-90. Zeno said its tests confirmed that the company’s technology can increase the specific power of its heat source compared with previously available strontium-90 heat sources.

Zeno uses radioisotope heat sources as the building blocks for its power-generating systems, which are designed to convert constant thermal energy into electricity. Strontium-90, which is typically created as a byproduct of nuclear fission, is an abundant fuel for such systems — but existing strontium-based power systems tend to be bulky. Zeno’s design could generate more power with less bulk, opening the way for a wider range of applications.

The work at PNNL involved radioactive and non-radioactive activities, including chemical processing and fuel fabrication, materials handling and heat source characterization. The test data will support further development of heat sources.

Could the Pacific Northwest become ‘Quantum Valley’?

California’s Silicon Valley may rule the roost for internet startups, and Kendall Square in the Boston area may set the pace for the biotech industry, but could the Pacific Northwest leap into the lead for quantum computing?

Experts who are exploring one of the computing world’s hottest frontiers say there’s a chance that Seattle could become the heart of a “Quantum Valley” — but it could take years for the promise of quantum computing to pay off.

“I’d say we’re on the order of a decade plus before we start to see this start to really materialize,” said Louis Terminello, associate laboratory director for physical and computational sciences at the U.S. Department of Energy’s Pacific Northwest National Laboratory.

Terminello is among the authors of a recent commentary calling for increased public investment to solidify the Pacific Northwest as home of the nation’s top regional cluster for research and development in quantum information science — in short, Quantum Valley.

An experiment that’s on its way to the International Space Station focuses on a subject that’s as common as dirt, but could be the key to growing crops in space.

The NASA-funded experiment — known as Dynamics of Microbiomes in Space, or DynaMoS — is being conducted by researchers at the Pacific Northwest National Laboratory. DynaMoS makes use soil and bacteria that were collected at a Washington State University field site in Prosser, Wash.

“Soil microbes are the hidden players of the life support system on planet Earth,” PNNL chief scientist Janet Jansson, the principal investigator for the DynaMoS experiment, explained during a pre-launch news briefing. The bacteria work to break down organic matter and make nutrients available for growing plants.

Space missions could extend the microbes’ reach beyond our home planet. “Soil microbes can help to make conditions on the lunar surface and Mars more favorable for plant growth,” Jansson said. “They can also be used to help grow crops on space stations and during long-term spaceflight.”

Dare we say it? Pacific Northwest National Laboratory has teamed up with IonQ to come up with a method for producing barium ions for quantum computing that could lead to … yes, that’s right, a quantum leap.

The public-private partnership could open up a new avenue for developing more resilient, more powerful hardware for trapped-ion quantum computers. The key technology involves using barium ions as the foundation for qubits, the quantum equivalent of binary bits in classical computing.

“IonQ’s work with PNNL to secure the domestic supply chain of IonQ’s quantum computing qubits is a fundamental step in the mass commercialization of quantum computing,” IonQ’s president and CEO, Peter Chapman, said today in a news release. “Qubits are at the core of our quantum computers, and this collaboration with PNNL lays the foundation for us to scale manufacturing of our systems.”

The partners say PNNL’s production process will provide a steady supply of barium-based qubits, using a microscopic smidgen of source material. That should make it possible for IonQ to reduce the size of core system components, which should in turn make it easier to network quantum computers.

Pacific Northwest National Laboratory is joining forces with two other research powerhouses to pioneer a new $5.5 million research center created by the U.S. Department of Energy to focus on the biggest challenges in artificial intelligence.

The Center for Artificial Intelligence-Focused Architectures and Algorithms, or ARIAA, will promote collaborative projects for scientists at PNNL in Richland, Wash., at Sandia National Laboratories in New Mexico, and at Georgia Tech. PNNL and Sandia are part of the Energy Department’s network of research labs.

ARIAA will be headed by Roberto Gioiosa, a senior research scientist at PNNL. As center director, he’ll be in charge of ARIAA’s overall vision, strategy and research direction. He’ll be assisted by two deputy directors, Sandia’s Rajamanickam and Georgia Tech Professor Tushar Krishna.

The creation of the new center is in line with the White House’s efforts to encourage partnerships in AI research. Last month, Energy Secretary Rick Perry announced the establishment of the DOE Artificial Intelligence and Technology Office to serve as a coordinating hub for all the work that’s being done in his department.
