In living cells, regulation of the electrochemical environment is supposed to be managed by ion channels—protein complexes that reside in cell membranes and assume definite shapes. So, it’s surprising ...

Innovations in imaging and genetic engineering are coming together to probe the biophysics of cytoplasm inside living animals.

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

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 ...

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 ...

Extracellular vesicles (EVs) are tiny membrane-bound particles released by cells to transport proteins and other molecules to neighboring cells. Because of this natural delivery ability, EVs have ...

All living organisms are made of cells, which are the smallest unit of life. Plants and animals have up to trillions of cells that work together to produce ever more intricate organization and ...

DNA in Cell Cytoplasm Implicated in Age-Related Blindness A new study suggests that DNA synthesized in the cell cytoplasm drives retinal cell death in an advanced form of age-related macular ...

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 ...
