Researchers at Aarhus University have developed a microscopic DNA needle that can deliver molecules directly into cells—and, ...

A set of new imaging tools now allows researchers to see how specific fat molecules, called phospholipids, are distributed ...

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 ...

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 ...
