A game of pool in the live cell

Cells need to react to environmental changes and maintain a balanced system of signaling cascades within the cell. Proteins outside of the cell, on the cellular surface, inside the cellular membrane, and within the cell orchestrate ...

How scientists analyze cell membranes

Exchange of material and information at the level of individual cells requires transport and signaling at the level of the plasma membrane enclosing the cell. Studying mechanisms at such tiny dimensions presents researchers ...

Intracellular transport in 3-D

Ludwig Maximilian University researchers have visualized the complex interplay between protein synthesis, transport and modification.

Islands in yeast membrane revealed by extreme microscopy

University of Groningen microbiologists have visualized tiny islands in the cell membrane of baker's yeast. These membrane compartments appear to store transport proteins before use. The scientists observed that these proteins ...

Does Titan's hydrocarbon soup hold a recipe for life?

NASA researchers have confirmed the existence in Titan's atmosphere of vinyl cyanide, which is an organic compound that could potentially provide the cellular membranes for microbial life to form in Titan's vast methane oceans. ...
