A Wave of Sticklebacks: How a Tiny Fish Takes Over an Entire Ecosystem

Large numbers of three-spined stickleback have gradually taken over larger parts of the Baltic Sea’s coastal ecosystem, shows a new scientific study. Stickleback is a small prey fish common in aquatic food webs across temperate Europe. The stickleback contributes to local ecosystem ‘regime shifts’, where young-of-the-year pike and perch decline in individual bays, and these shifts gradually spread like a wave from the outer archipelago into the mainland coast.

Measuring Adhesion and Friction of Polymer Nanofibers

Using a device small enough to fit on the head of a pin, researchers at the University of Illinois at Urbana-Champaign gained new knowledge about the properties of polymer fibers at the nanoscale — knowledge that can inform the design and manufacturing of products made up of random networks of filaments, such as robust filters designed to block foreign particles from entering our lungs.
