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.

Real-time oxygen measurements expose hidden losses in solar water splitting
A new technique developed at Imperial College London measures oxygen production in real time, revealing hidden losses in solar water splitting. The researchers found that electrical current did not always correspond to oxygen generation in hematite, one of the most widely studied

Nitrogen fixation 'off switch' discovery could one day help crops make their own fertilizer
Nitrogen is essential for life. It's needed to build proteins, DNA and many other components of cells. Although nitrogen gas makes up almost 80% of Earth's atmosphere, most organisms cannot use it directly. Certain microbes solve this problem through a process called nitrogen fix

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
