Who needs science fiction when you have the mitochondria? Billions of years ago, early plant and animal cells were infected by protobacteria which sought refuge from the outside world. Over time, these bacteria formed a symbiosis ...
By giving living cells a "nano-poke" and monitoring the resulting changes in the intracellular environment, researchers have gotten their first glimpse of how whole cells respond to external mechanical pressure.
