Polymer discovery gives 3D-printed sand super strength

Researchers at the Department of Energy's Oak Ridge National Laboratory designed a novel polymer to bind and strengthen silica sand for binder jet additive manufacturing, a 3D-printing method used by industries for prototyping and part production.

Capturing a true picture of wolves in Yellowstone: Reevaluating aspen recovery

It's an environmental success story that feels like a parable—the reintroduction of wolves in Yellowstone National Park in the mid-1990s triggered a cascade of effects that ultimately restored the ecosystem, including the recovery of aspen trees. But like many stories based on ecological realities, it's more complex than at first glance—aspen recovery in the park is not as robust as generally...

Illuminating dark matter in human DNA

Researchers at University of California San Diego have produced a single-cell chromatin atlas for the human genome. Chromatin is a complex of DNA and protein found in eukaryotic cells; regions of chromatin at key gene regulatory elements appear in open configurations within certain cell nuclei. Precisely delineating these accessible chromatin regions in cells of different human tissue types would...
