Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...
Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...
Cells have always hummed with activity. They make their own energy, package it into molecules like ATP, and spend it ...
Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers.
