Chemists induced a cell-like behavior in molecular assemblies called vesicles. They used a sacrificial chemical fuel to make the vesicles divide into smaller versions of themselves. While this process ...

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.

Just one enzyme manages the refilling of the cellular soda machine that replicates our genes. PLK-1 initiates a process in two protein groups, leading to creation of new CENP-A proteins. These CENP-A ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

A cell copies all of its DNA, gears up to split in two, and then just… doesn’t. It sits there, swollen with a double genome, and nobody notices. This kind of silent failure has been observed in labs ...

During animal cell division, a highly synchronized and tightly regulated dance of chromosomes takes place, ensuring the chromosomes split correctly into the two cells. Spindle fibers - complex ...

Researchers have revealed a surprising new role for a key protein in cell division. The discovery, reported in two back-to-back papers, challenges long-standing models and textbook accounts in biology ...

Many cellular functions in the human body are controlled by biological droplets called Liquid-Liquid Phase Separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside ...

A time-delay circuit enables precise control over the division of synthetic DNA droplets, which mimic biological Liquid-Liquid Phase Separation (LLPS) droplets found in cells. By utilizing a ...
