Collaborating bacteria sacrifice themselves for the greater good
Like ants, termites and bees, some bacteria work together as a multicellular group. There is a strict division of labour in such colonies, to make the group more resilient to the outside world. Now researchers have found that some parts of the bacterial colony can take ‘for the greater good’ to a whole…
