Bacteria in the gut do far more than help digest food in the stomachs of their hosts; they can also tell the genes in their mammalian hosts what to do. A study describes a form of ‘interspecies communication’ in which bacteria secrete a specific molecule — nitric oxide — that allows them to communicate with and control their hosts’ DNA, and suggests that the conversation between the two may broadly influence human health.

Fat cells in the human body have their own internal clocks and exhibit circadian rhythms affecting critical metabolic functions, new research finds.

Researchers have identified one of the main mechanisms behind the repair of serious damage to the human DNA.
