Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory developed a new algorithm to bolster what once were static models of root dynamics, providing researchers a clearer picture of what's really happening beneath the soil. The work, published in the January 28 issue of the Journal of Advances in Modeling Earth Systems, describes the dynamic root model and its use with the Energy Exascale Earth System Land Model (ELM), a component of the DOE's larger Energy Exascale Earth System Model (E3SM).
Scientists discovered how iron atoms continually re-arrange on surfaces, offering insights into metal corrosion and soil remediation.
Detailed 3D images show how nanoparticles change in reactions that purify contaminated water or power recyclable geochemical batteries.
Scientists studying plant cell walls have discovered mechanistic details of a protein involved in the assembly of lignin, a key cell-wall component. The protein acts as a targeted "electron shuttle," delivering the "fuel" that drives the construction of one specific lignin building block. Controlling the flow of electrons by targeting shuttle proteins could be a new strategy for guiding plants to make desired products.

Scientists at the Sensitive Instrument Facility of the U.S. Department of Energy's Ames Laboratory achieved real-time atom rearrangement monitoring using aberration-corrected scanning transmission electron microscopy during the synthesis of intermetallic nanoparticles (iNPs).
Human-caused pollution spurs the production of climate-changing particles known as secondary organic aerosols much more than previously thought. Researchers made the finding by analyzing air samples that were captured aboard a research aircraft as it zig-zagged between pristine air over the Amazon rainforest and polluted air over the city of Manaus.

Scientists have proposed a new method for producing more robust Majorana fermions, a kind of quasiparticle that could act as stable bits of information in next-generation quantum computers.
For the first time ever, scientists have imaged the process by which an individual immune system molecule is switched on in response to a signal from the environment. The new work provides an enormous leap forward in our understanding of how T cells detect viruses and may provide unique insights into autoimmune diseases and cancer immunotherapy.
The BISICLES ice sheet model uses high performance computing resources at the National Energy Research Scientific Computing Center (NERSC) to systematically examine where the Antarctic Ice Sheet is vulnerable and the resulting potential for large contributions to sea level rise.
To accelerate the process of identifying novel uranium oxide phases, an ORNL team studied 4,600 different potential crystal structures of uranium oxide compositions on Metis, a CADES high-performance computing cluster. An improved understanding of uranium oxides, which fuel the vast majority of the U.S. nuclear power fleet, could lead to the development of improved fuels or waste storage materials.
UPTON, NY--For the first time, a team of researchers from Stony Brook University and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have revealed the molecular structure of membranes used in reverse osmosis. The research is reported in a recently published paper in ACS Macro Letters, a journal of the American Chemical Society (ACS).
To function properly, proteins must morph into specific 3D shapes through a biophysical phenomenon called protein folding. Researchers at ORNL are using various deep-learning techniques to study the intermediate protein stages between the initial unfolded state and the final folded state, which are notoriously difficult to characterize. These methods could also help identify factors that cause proteins to "misfold" into dysfunctional shapes, a phenomenon often attributed as a leading factor in the development of diseases including Alzheimer's, cardiovascular disorders, and diabetes.
An Argonne scientist has new ways of accelerating the development of new organic materials for electronics. The new approaches could have applications in other types of materials science research.
Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have developed a new technique that combines the power of microscale "tractor beams" with high-powered X-rays, enabling them to see and manipulate crystals freely floating in solution.
A team of researchers working at Berkeley Lab has discovered the strongest topological conductor yet, in the form of thin crystal samples that have a spiral-staircase structure. The team's result is reported in the March 20 edition of the journal Nature.
Direct observations of the structure and catalytic mechanism of a prototypical kinase enzyme--protein kinase A or PKA--will provide researchers and drug developers with significantly enhanced abilities to understand and treat fatal diseases and neurological disorders such as cancer, diabetes, and cystic fibrosis. The discovery was made by an international team of researchers using macromolecular neutron crystallography at the Department of Energy's Oak Ridge National Laboratory and the Institut Laue-Langevin in Grenoble, France.
