Sticky spots on cell membranes hold onto the master regulator of cell polarity, helping to ensure that the regulatory protein accumulates in high enough concentrations to trigger cell polarity. Over ...

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 ...

Determining the properties of biomolecules—particularly of proteins—in their natural environment is a critical step in analyzing their functions and elucidating the mechanisms behind cellular and ...
