Biologists have long treated cell membranes as passive barriers, thin skins that separate the chemistry of life from 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 ...

While our cells are performing some important, basic functions, they can generate compounds known as reactive oxygen species ...

Researchers have determined that condensates are electrically charged droplets that can induce voltage changes across the ...

Cells have always hummed with activity. They make their own energy, package it into molecules like ATP, and spend it ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

Schematic of UV-W process. (a) Schematic of UV-W process. (b) Positron annihilation lifetime spectroscopy of the PEI-IIM, PEI-ICM with UV-W process 20 h and 40 h. (c) Ion permeation and selectivity ...

This is an important study on the sensory roles of Cerebrospinal fluid-contacting neurons (CBF-cn) in mammals. The authors identify PKD2L1 as the predominant pH-sensing channel CBF-cn and show how the ...

For the first time, researchers have been able to show how a cell closes the door to free radicals - small oxygen molecules that are sometimes needed ...

Scientists describe the design and construction of artificial membrane channels, engineered using short segments of DNA. The DNA constructions behave much in the manner of natural cell channels or ...
