Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.
How does evolution select the fittest “individuals” when they are ecosystems made up of hosts and their microbiomes? Biologist debate the need to revise theories.
Just as antibiotics have bred resistance in bacteria, vaccines can potentially lose their effectiveness over diseases they controlled. Researchers are working to head off the evolution of new threats.
To date the branches on the evolutionary tree of life, researchers are looking at horizontal gene transfers among ancient microorganisms, which once seemed only to muddle the record.
To discover our species’ deep history and to shape its future health, we should learn from the microbes that accompanied us on our evolutionary journey.
If gut bacteria can sway their hosts to be selfless, it could answer a riddle that goes back to Darwin.
Scientists are having a difficult time finding a treatment for the Zika virus in part because so few drugs are safe for pregnant women. But one antibiotic has shown promise.
Researchers are racing to understand how the Zika virus causes birth defects. Their first results have revealed tantalizing clues about how the virus interferes with the developing brain — and how it might be stopped.
A single genetic change and some clever geometry show how single-celled organisms can band together to form cooperative multicellular entities.
