Scientists uncover extreme life inside the Arctic ice
In brief Researchers studied single-celled algae, called diatoms, from the Arctic that were previously assumed to be hibernating in the ice and found they were actually quite active. This activity, which continued when temperatures dropped to -15 C, is the coldest-ever movement recorded for a eukaryotic cell. The diatoms move through a type of gliding, which is enabled by a combination of mucus and molecular motors that are similar to systems seen in human muscles. Given how abundant these di
