Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions.

Scientists at the University of Helsinki discovered how plants heal their protective outer layer, the periderm. The diffusion ...

The membrane then self-assembled on the water’s surface, allowing us to extract it and install it into the diffusion cell. Despite being so thin, the material proved to be quite robust.

Abstract: The lateral diffusion coefficients of the lipid cell membrane molecules of HeLa cells were measured by fluorescence recovery after photobleaching (FRAP) with the irradiation of 0.10 and 0.29 ...

Diffusion occurs along the concentration gradient of the substance. If the substance is lipid-soluble (e.g., oxygen), it can pass through the phospholipid bilayer of the membrane. If the substance is ...

Past experiments rationalized the observed dynamic heterogeneity and non-Gaussian diffusion in living cell membranes in terms of slow-active remodeling of the underlying cortical actin network. In ...

In this Snack, students notice: Materials that are like the membrane easily pass through, while those that are unlike the membrane do not. Channels can be used in cases where materials do not ...

All biological cells require the transport of materials across the plasma membrane into and out of the cell. By infusing cubes of agar with a pH indicator, and then soaking the treated cubes in ...
