From spiders spinning their webs to the manufacturing of textiles, the formation of fibers from liquids plays an important role in both nature and industry. Yet accurately predicting the properties of such fibers remains a challenge. The fiber is often much thinner than the nozzle from which a polymer or solution is extruded.

Factors such as temperature, flow conditions and chemical reactions ultimately determine a fiber's thickness and strength.

How enzyme activity can accelerate molecular movement inside cells

A cell sitting in fluid looks like one of the most passive things in biology. Nutrients drift toward it on the aimless currents of molecular motion, and now and then one bumps into the right spot on the cell's surface and gets pulled inside. This impression of the cell as a lotte
