New experimental results have cast doubt on earlier proposals suggesting that spherical, cell-like membranes could form in ...
When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...
A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) interwoven through in the cell’s chromosome (red). Right side shows all the ...
In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an ...
A well-fitted ‘disguise’ allows transplanted mitochondria to slip into cells whose own mitochondria are defective, scientists reported 18 March in Cell 1. Administration of these cloaked mitochondria ...
Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This ...
A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.
Scientists simulated an asteroid impact, and Deinococcus radiodurans’ cell membranes made it through. This suggests that life ...
A three-dimensional model of different organelle membranes created from high-resolution imaging data reveals that membranes vary in thickness. Darker colors indicate thicker regions of the membrane, ...
Many biological processes are regulated by electricity-from nerve impulses to heartbeats to the movement of molecules in and out of cells. A new study by Scripps Research scientists reveals a ...
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 ...
Cholesterol enhances melanoma cell invasion by making nuclei squishier, revealing a potential treatment target in cancer progression.
