    A Fresh Look at Measuring the Exposome

    The human exposome is the totality of all environmental exposures in a lifetime, internal and external, including those before birth, from the chemical, biological, and social agents that influence human health. A new paper from PNNL explores one option for improving the coverage, dynamic range, and throughput of exposome measurements.

    PNNL-Led Co-Design Center to Enhance Graph Algorithms for ECP

    ExaGraph: Combinatorial Methods for Enabling Exascale Applications, was selected as the fifth Exascale Computing Project Co-Design Center. The PNNL-led center will focus on graph analytics, primarily combinatorial (graph) kernels that can access computing system resources to enhance data analytic computing applications. Mahantesh Halappanavar, of ACMD Division’s Data Sciences group, will lead the new ECP center.

    Particles Carry Toxic Pollutants Far from Home

    Combining state-of-the-art atmospheric modeling with the latest measurements-based findings, researchers at PNNL found that toxic particles can last longer and travel much farther than previous models predicted. The new insights indicate an estimate of global lung cancer risk from these pollutants four times higher than previously thought.

    Tipping Water: Finding the Balance Between Keeping Molecules Whole or Splitting Them on Oxides

    Scientists at Pacific Northwest National Laboratory definitively resolved a long-standing controversy and showed that molecular water is more stable on titania surface than the hydroxyl fragments.

Our researchers advance the frontiers of science to study, predict, and engineer complex adaptive systems related to Earth, energy, and security. Our investigations inhabit every scale. We study the vast whirl of aerosol-laden clouds; the complex shoreline interfaces of land and sea; the mysterious microbiomes that teem just beneath the Earth’s surface; and the myriad of molecules busy on surfaces just angstroms wide.

We investigate elemental chemical and physical processes, including new catalysts that speed up the efficiency of renewable fuels. We study climate system dynamics to predict the effects of climate change. We design and synthesize the functional and structural materials of the future, including robust metal foils thinner than a human hair.

We are proud to host two unique DOE user facilities. EMSL facilitates molecular-level investigations into the physical, chemical, and biological processes that underlie the Earth’s most critical environmental issues. ARM provides a setting for climate research and instrumentation development, and is strengthened by streaming data from a worldwide complex of sensing stations.
