Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great-grandparent of all living things. Many believe LUCA was little more than a crude assemblage of molecular parts, a chemical ...

Designer organelles bring new functionalities into cells

For the first time, scientists have engineered the complex biological process of translation into a designer organelle in a living mammalian cell. Research by the Lemke group at the European Molecular Biology Laboratory (EMBL) ...

Researchers uncover intracellular longevity pathway

The search for clues on how to live healthier, longer lives has led researchers at Baylor College of Medicine to look inside the cells of the worm Caenorhabditis elegans. The researchers report in the journal Developmental ...

A game of pool in the live cell

Cells need to react to environmental changes and maintain a balanced system of signaling cascades within the cell. Proteins outside of the cell, on the cellular surface, inside the cellular membrane, and within the cell orchestrate ...
