(Phys.org) —In 1958 a group of scientists working in Denmark made the striking observation that bacterial cells are about twice as large when they are cultured on a rich nutrient source than when they are cultured on a meager one. When they are shifted from a nutrient-poor environment to a nutrient-rich one, they bulk up until they have achieved a size more appropriate to their new growth conditions.
