For decades, researchers have been using equations derived in the mid-1970s for a variety of fluid applications involving inks, foams, and bubbles, among other uses. These fundamental fluid equations describe how much force ...
(Phys.org) —When a rubber ball and a droplet of water are compressed onto a solid surface, they behave very differently. For the ball, the compression process is reversible, so the ball retains its original form when decompressed. ...
(PhysOrg.com) -- Researchers have fabricated a fluidic antenna that can change its shape, and therefore the frequency at which it resonates, in response to pressure in a controlled and predictable manner. Shape-changing antennas ...
Scientists aren't entirely sure how life began on Earth, but one prevailing theory posits that persistent cycles of wet and dry conditions on land helped assemble the complex chemical building blocks necessary for microbial ...
