This robot doesn't need any electronics
Engineers at the University of California San Diego have created a four-legged soft robot that doesn't need any electronics to work. The robot only needs a constant source of pressurized air for all its functions, including its controls and locomotion systems. The team, led by Michael T. Tolley, a professor of mechanical engineering at the Jacobs School of Engineering at UC San Diego, details its findings in the Feb. 17, 2021 issue of Science Robotics. (2021-02-17)

The water surface is a fantastic place for chemical reactions
Using an advanced technique, scientists from the RIKEN Cluster for Pioneering Research have demonstrated that a chemical reaction powered by light takes place ten thousand times faster at the air-water interface--what we usually call the water surface--than in the bulk of the water, even when the light has equivalent energy. This finding could help our understanding of the many important chemical and biological processes that take place at the water surface. (2021-02-15)

These shrimplike crustaceans are the fastest snappers in the sea
The snapping claws of male amphipods--tiny, shrimplike crustaceans--are among the fastest and most energetic of any life on Earth. Researchers reporting in the journal Current Biology on February 8 find that the crustaceans can repeatedly close their claws in less than 0.01% of a second, generating high-energy water jets and audible pops. The snapping claws are so fast, they almost defy the laws of physics. (2021-02-08)

Shuffling bubbles reveal how liquid foams evolve
Tokyo, Japan - Researchers from Tokyo Metropolitan University studied the dynamics of foams.
