Cell nuclei harbor factories that transcribe genes

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...

New methods to visualize bacterial cell-to-cell communication

Most bacteria are able to communicate with each other by secreting signaling molecules. Once the concentration of signals has reached a critical density ("the Quorum), the bacteria are able to coordinate their behavior. Only ...

Researchers strike gold with nanotech vaccine

Scientists in the US have developed a novel vaccination method that uses tiny gold particles to mimic a virus and carry specific proteins to the body's specialist immune cells.

Quantum microscope for living biology

(Phys.org)—A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells.

Researchers decipher the mecanism of membrane fission

A cell is composed of a nucleus which encloses its genetic information and the cytoplasm which is itself confined by an external membrane separating the cell from the outside world. The impermeability of the membrane and ...
