Zeolites crystals, used among other things for refining petroleum to gasoline and biomass into biofuels, are the most-used catalysts by weight on the planet, and discovering mechanisms of how they…
Atomic-level studies of the architecture of tiny sodium channel proteins, critical to generating electrical signals that start off each beat of the heart, are imparting striking details about their function,…
Protein-like molecules called "polypeptoids" (or "peptoids," for short) have great promise as precision building blocks for creating a variety of designer nanomaterials, like flexible nanosheets - ultrathin, atomic-scale 2D materials.…
In a paper in Science this week, Penn researchers report the first detailed molecular characterization of how every cell changes during animal embryonic development. The work, led by the laboratories…
NASA has selected Southwest Research Institute to lead the "Polarimeter to Unify the Corona and Heliosphere" (PUNCH) mission, a landmark Small Explorers Program mission that will image beyond the Sun's…
Bacteria are everywhere. They live in the soil and water, on our skin and in our bodies. Some are pathogenic, meaning they cause disease or infection. To design effective treatments…
