Bone and mollusk shells are composite systems that combine living cells and inorganic components. This allows them to regenerate and change structure while also being very strong and durable. Borrowing from this amazing complexity, researchers have been exploring a new class of materials called engineered living materials (ELMs).

Excavating Quantum Information Buried in Noise
Department of Energy, Office of Science

Researchers developed two new methods to assess and remove error in how scientists measure quantum systems. By reducing quantum “noise” – uncertainty inherent to quantum processes – these new methods improve accuracy and precision.

Lanthanum strontium manganite (LSMO) is a widely applicable material, from magnetic tunnel junctions to solid oxide fuel cells. However, when it gets thin, its behavior changes for the worse. The reason why was not known. Now, using two theoretical methods, a team determined what happens.

Newswise: When Ions and Molecules Cluster

When Ions and Molecules Cluster
Department of Energy, Office of Science

How an ion behaves when isolated within an analytical instrument can differ from how it behaves in the environment. Now, Xue-Bin Wang at Pacific Northwest National Laboratory devised a way to bring ions and molecules together in clusters to better discover their properties and predict their behavior.

Newswise: Tune in to Tetrahedral Superstructures

Tune in to Tetrahedral Superstructures
Department of Energy, Office of Science

Shape affects how the particles fit together and, in turn, the resulting material. For the first time, a team observed the self-assembly of nanoparticles with tetrahedral shapes.

Newswise: Tracing Interstellar Dust Back to the Solar System’s Formation

Tracing Interstellar Dust Back to the Solar System’s Formation
Department of Energy, Office of Science

This study is the first to confirm dust particles pre-dating the formation of our solar system. Further study of these materials will enable a deeper understanding of the processes that formed and have since altered them.

Newswise: Investigating Materials that Can Go the Distance in Fusion Reactors

Investigating Materials that Can Go the Distance in Fusion Reactors
Department of Energy, Office of Science

Future fusion reactors will require materials that can withstand extreme operating conditions, including being bombarded by high-energy neutrons at high temperatures. Scientists recently irradiated titanium diboride (TiB2) in the High Flux Isotope Reactor (HFIR) to better understand the effects of fusion neutrons on performance.

Newswise: Better 3-D Imaging of Tumors in the Breast with Less Radiation

Microbes are Metabolic Specialists
Department of Energy, Office of Science

Scientists can use genetic information to measure if microbes in the environment can perform specific ecological roles. Researchers recently analyzed the genomes of over 6,000 microbial species.
