Many bacteria can move using a variety of mechanisms: flagella are used for swimming through fluids; bacterial gliding and twitching motility move bacteria across surfaces; and changes of buoyancy allow vertical motion. | Many bacteria can move using a variety of mechanisms: flagella are used for swimming through fluids; bacterial gliding and twitching motility move bacteria across surfaces; and changes of buoyancy allow vertical motion. | ||
Swimming bacteria frequently move near 10 body lengths per second and a few as fast as 100. This makes them at least as fast as fish, on a relative scale.[135] | Swimming bacteria frequently move near 10 body lengths per second and a few as fast as 100.

E. coli was one of the first organisms to have its genome sequenced; the complete genome of E. coli K12 was published by Science in 1997. | E. coli was one of the first organisms to have its genome sequenced; the complete genome of E. coli K12 was published by Science in 1997. | ||
By evaluating the possible combination of nanotechnologies with landscape ecology, complex habitat landscapes can be generated with details at the nanoscale. | By evaluating the possible combination of nanotechnologies with landscape ecology, complex habitat landscapes can be generated with details at the nanoscale. On such synthetic ecosystems, evolutionary experiments with E. coli have been performed to study the spatial biophysics of adaptation in an island biogeography on-chip. | ||
Studies are also being performed attempting to program E. coli to solve complicated mathematics problems, such as the Hamiltonian path problem. | Studies are also being performed attempting to program E. coli to solve complicated mathematics problems, such as the Hamiltonian path problem. | ||
