A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.

Despite its importance to the survival of our cells, the processes of plasma membrane repair have remained elusive. Their relevance is underscored by the fact that mutations in plasma membrane repair ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ensure the signal reaches the correct effector without triggering pathways ...

Cholesterol is an essential component of the membrane surrounding every human cell, despite its poor reputation as a health concern when its blood levels are too high. The key to health is having the ...

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 ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...

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 ...
