How cytoplasm 'feels' to a cell's components

Under a microscope, a cell's cytoplasm can resemble a tiny underwater version of New York's Times Square: Thousands of proteins swarm through a cytoplasm's watery environment, coming together and breaking apart like a cytoskeletal ...

Collaborative research reveals a new view of cell division

Basic research into the mechanisms of cell division, using eggs and embryos from frogs and starfish, has led researchers to an unexpected discovery about how animal cells control the forces that shape themselves.

Inside the cell, an ocean of buffeting waves

Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However, a new biophysical study led ...

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.
