Cells that are about to die send a signal to an executioner protein, but sometimes, those cells can fight back and regenerate ...

Structures called desmosomes connect cells to each other and transfer mechanical stress. They are especially important in tissues under continual mechanical stress, such as heart muscle (pictured).

Cells do this by breaking proteins down and recycling them, a process summarily referred to as "protein removal." But this ongoing and vital "dance" of protein making and protein removal takes energy ...

Like workers at a factory or office, proteins in a cell must be in the right department to do their jobs. But scientists have yet to fully map the cell’s organization, much less determine how these ...

Inside every living cell, proteins and membranes are in constant motion, reshaping, colliding, and flexing as they keep an ...

Researchers at the University of Geneva mapped how hundreds of lipids are transported inside cells, revealing that each lipid ...

When the cell's recycling stations, the lysosomes, start leaking, it can become dangerous. Toxic waste risks spreading and ...

Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids, but cannot simply accumulate inside the cell forever. Once they have done their ...
