Small-scale analysis of RNA diffusion rates throughout cells of yeast and bacteria reveals that rates of change of entropy in certain time intervals are larger in areas with higher diffusion rates, ...

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

Tight junctions are intercellular adhesion complexes in epithelia and endothelia that control paracellular permeability. This paracellular diffusion barrier is semipermeable: it is size- and ...

The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions ...
