Sticky electrons: When repulsion turns into attraction

Materials can assume completely different properties depending on temperature, pressure, electrical voltage or other physical quantities. In theoretical solid-state physics, state-of-the-art computer models are used to understand ...

Lab explores new resins for light-based 3-D printing

A Lawrence Livermore National Laboratory (LLNL) team has simulated the cross-linking of 3-D-printed polymer networks, a key step toward developing new functional resins for light-based 3-D-printing techniques including two-photon ...

Chemists make cellular forces visible at the molecular scale

Scientists have developed a new technique using tools made of luminescent DNA, lit up like fireflies, to visualize the mechanical forces of cells at the molecular level. Nature Methods published the work, led by chemists ...

Decoding material wear with supercomputers

Wear and friction are crucial issues in many industrial sectors: What happens when one surface slides across another? Which changes must be expected in the material? What does this mean for the durability and safety of machines?

Growing back the lymph system

A team including University of Georgia researchers has for the first time documented the regrowth of surgically removed pathways in the lymphatic system, a network of vessels designed to pump away inflammatory fluids and ...
