Salt and Dunes
Photographer Barbara Brown captured these striking aerial views in Namibia. Coastal dunes and saltworks feature in the photos from Walvis Bay, where wind, waves, evaporation, and humankind have shaped the landscape. The colorful and dendritic dune images come from Sossusvlei, where the ephemeral Tsauchab River ends in the Namib Desert. Recent flooding left its mark on the dry landscape. (Image credit: B.

Vanishing Spirits: Cognac
Years ago, photographer Ernie Button discovered an intriguing stain left behind in his whiskey glass after the last drops evaporated. That discovery led both to beautiful images and an entire scientific paper analyzing how the alcohol, surfactants, and polymers in the whiskey combined to leave such a uniform stain. Over the years, Button continued investigating liquor stains, looking at gin, rice whisky, and aging effects. Here, he’s turned his lens to cognac, producing stains that look like oil slicks, aerial landscapes, and even cartoonish faces! (Image and submission credit: E. Button)

“Crystal Garden – Seasons”
In this latest project, the Beauty of Science team explores colorful crystallization as chemicals precipitate out of evaporating solutions. The variety of shapes and colors is incredible. To see many more of these crystalline “gardens,” check out the video below and the project’s webpage. (Video and image credit: W. Zhu/Beauty of Science; via Colossal)

Quick-Drying, Fast-Cracking
Water droplets filled with nanoparticles leave behind deposits as they evaporate. Like a coffee ring, particles in the evaporating droplet tend to gather at the drop’s edge (left). As the water evaporates, the deposit grows inward (center) and cracks start to form radially. After just a couple minutes, the solid deposit covers the entire area of the original droplet and is shot through with cracks (right).
Researchers found that the cracks’ patterns and propagation are predictable through a model that balances the local elastic energy and and the energy cost of fracture. They also found that the spacing between radial cracks depends on the deposit’s local thickness. Besides explaining the patterns seen here, these cracking models could help analyze old paintings, where cracks could hide information about the artist’s methods and the artwork’s condition.
