Under the right conditions, sand can flow. When heavier grains are placed atop lighter grains in a container, the less dense grains can burble upward like the blobs of a lava lamp, a study finds. The ...

Researchers combined physics and machine learning to develop a new 3D-printing technique that can quickly create complex physical patterns -- including replicating a segment of a Pollock painting -- ...

A University of Michigan study published March 13 found evidence that Crow instability— a line-vortex instability that occurs when the wingtip of an aircraft interacts with condensed water, called ...

In many plumbing and pipework systems in general, there are junctions and connections to move liquids such as water in different directions, but have you ever thought about what happens to the water ...

Quantum turbulence The swirling patterns in Vincent van Gogh’s “The Starry Night” can help us visualize the quantum Kelvin-Helmholtz instability (KHI). The central spiral and surrounding stars and ...

You don't have to be an experienced trailblazer to know that if you choose to hike in the heat, you better be hydrated. Yet scientific literature on the subject reports that roughly 25% of ...
