What if we could program living cells to do what we would like them to do in the body? Having such control—a major goal of synthetic biology—could allow for the development of cell-based therapies that might one day replace ...

Individual bacterial cells have short memories. But groups of bacteria can develop a collective memory that can increase their tolerance to stress. This has been demonstrated experimentally for the first time in a study by ...

(Phys.org)—A small team of researchers with the University of California and Rice University has created a model of chemotaxis that shows how individual cells may work together to respond to a chemical-concentration gradient. ...
A team of biologists and physicists at UC San Diego has uncovered in detail the dynamic process that allows the multi-tentacle Hydra, a tiny freshwater animal distantly related to the sea anemone, to open and close its mouth.

The micro-environment surrounding cancer cells is just as important as genes in regulating tumour progression. Scientists have therefore examined the biophysical and biochemical cues occurring in the vicinity of cancer cells. ...

When it comes to communicating, cells perform better in crowds. When too many work together, though, the cells end up in a game of "telephone," passing on increasingly unreliable signals.
