Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes, regulating ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

Just as countries import a vast array of consumer goods across national borders, so living cells are engaged in a lively import-export business. Their ports of entry are sophisticated transport ...

Working with light to activate processes within genetically modified fission yeast cells is among the research performed by the experimental biologists in the Martin Lab at the University of Lausanne, ...

Photons of light possess linear and angular momentum. This fundamental characteristic is crucial to trapping objects optically using a highly focused laser beam. Using this light feature, the Optical ...
