Bacterium alters its genome to adapt to new conditions

Researchers: Achromatium is special in many respects: It is 30,000 times larger than its “normal” counterparts that live in water and owing to its calcite deposits it is visible to the naked eye. It has several hundred chromosomes, which are most likely not identical. This makes Achromatium the only known bacterium with several different genomes.

Bacteria are smarter than we think

At Wired: As they cleared paths of food, the E.coli tended to move toward unexplored, broth-rich areas, which ultimately helped them evacuate the maze. It took about 10 hours for about 1 percent of the multiple generations of bacteria to collectively solve the puzzle. That may not sound fast, but it’s five times faster than if the organisms had just been swimming around randomly, says Phan.
