A tiny bubble of lipids, enzymes and DNA has done something biologists have chased for years: it carried out a full cycle of life-like behavior without starting from a living cell. The system, called SpudCell,

Learn how SpudCell, a synthetic cell built from chemical parts, can grow, divide, copy its DNA, and bring life-like behavior closer to engineering.

Scientists have long understood that parts of cells, called organelles, evolved to have certain shapes and sizes because their forms are closely related to how they function. Now, Johns Hopkins researchers have developed a bacteria-based tool to test ...

Cells degrade components that are no longer needed through autophagy. New results show that a weak molecular interaction is essential for this process. By modifying this interaction, it is possible to artificially trigger autophagy, which could then enable ...
