Acceptance of animals in urban environments      (via sciencedaily.com)     Original source 

How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.

Researchers 'unzip' 2D materials with lasers      (via sciencedaily.com)     Original source 

Researchers used commercially available tabletop lasers to create tiny, atomically sharp nanostructures in samples of a layered 2D material called hexagonal Boron Nitride (hBN). The new nanopatterning technique is a simple way to modify materials with light--and it doesn't involve an expensive and resource-intensive clean room.

The Clues for Cleaner Water      (via sciencedaily.com)     Original source 

By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.
