Human cells are extremely small and tightly packed – at about 20 micrometers across, ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers.

Deep within the intricate world of cellular biology, scientists at Weill Cornell Medicine have made a remarkable discovery about aging that could transform our understanding of human longevity. Their ...

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 ...

Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring ...

(a) The specific structure of a natural biological cell membrane, which owns an ultrathin structure and a dual hydrophilic-hydrophobic character. (b) Interface strain as the driving force to curl the ...

Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before. This breakthrough may help explain why immunotherapy works for some ...

The original version of this story appeared in Quanta Magazine. The bottom of the ocean is cold, dark, and under extreme pressure. It is not a place suited to the physiology of us surface dwellers: At ...
