When a bacterial cell divides into two daughter cells there can be an uneven distribution of cellular organelles. The resulting cells can behave differently from each other, giving them an evolutionary advantage.
New research shows bacteria may draw other bacteria to an infection site by laying down trails of a “molecular glue” that attract free-swimming individual bacteria.
The Erasmus virus resets 207 genes in lung cells to hamper the cells’ ability to launch an antiviral reaction. Available drugs might correct this sabotage.
Latest research findings suggest the possibility of reverting TB hyper-susceptibility to TB hyper-resistance.
Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. UW scientists consider the genetic underpinnings of such evolutionary rescue.
