How do our cells communicate?
In order to function, the cells in our bodies need to coordinate and pass information, say, if we need a burst of energy to flee a threat. But, without eyes, ears, or even radios, how do they signal this information reliably?
“The only way to communicate, and this is actually a big challenge for biology, is by basically sending out groups of molecules which then can interact with other molecules,” said Professor Mike Hinczewski, a biophysicist at Case Western Reserve University. “There’s going to be lots of noise, and so biology has to figure out a way of compensating for that degradation of the signal.”
