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 ...

Pollen is the male gametophyte of flowering plants, the typically haploid generation of the plant life cycle that produces the male gametes. Upon germination, pollen grains extend a pollen tube to ...

Structure of the cell membrane and conceptual diagrams of (a) short-range viscosity and (b) long-range viscosity. (a) Random thermal motion of lipids on a nanometer scale is not impeded by proteins or ...

Single-cell heterogeneity is a defining feature of biology and medicine, and the cell membrane presents spatially heterogeneous biochemicals that govern cellular interactions. Although fluorescence ...

Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do ...

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 ...
