In search of universal laws of diffusion with resetting

The manner in which animals penetrate a neighborhood searching for food shows similarities to the movements of liquid particles in plant capillaries or gas molecules near an absorbing wall. These phenomena—and many others ...

Assigning moving features in high-speed atomic force microscopy

Researchers at Kanazawa University report in Biophysics and Physicobiology how to optimize high-speed atomic force microscopy experiments on live cell membranes, so that moving objects like molecules can be properly followed ...

New ultra-faint dwarf galaxy discovered

Astronomers from the University of Arizona (UA) and elsewhere report the discovery of a new ultra-faint dwarf galaxy. The newfound galaxy, designated Tucana B, is the first quenched and isolated object of this type identified ...

How cells control their borders

Bacteria, fungi, and yeast are very good at excreting useful substances such as weak acids. One way in which they do this is through passive diffusion of molecules across the cell membrane. At the same time, cells need to ...
