Researchers are examining the power of subtle genetic weaknesses in the immune system to affect the severity of infectious diseases, including COVID-19.
John Priscu’s search for life that thrives under ice took him to subglacial lakes at the South Pole. Now he has his eye on Mars and Europa.
New studies revise ideas about the symbiosis that gave mitochondria to cells and about whether the last common ancestor of all eukaryotes was one cell or many.
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.
