An insect's gut might seem an inhospitable place to settle in, but diverse microbes nonetheless make their home there. Yet in the gut, there's a struggle for the nutrients needed to survive among the resident bacteria and ...

To a great extent, living organisms control the flows of matter and energy through the planet, and the study of their interactions is the goal of ecology. While the roles or functions of multicellular organisms, such as trees ...

Nearly half of the human genome is composed of genetic parasites—transposons, plasmids, viruses, and other genetic elements that have one thing in common: they don't make any beneficial contributions to their hosts, and ...
Rice University scientists have released the first results of extensive water sampling in Houston after the epic flooding caused by Hurricane Harvey. They found widespread contamination by E. coli, likely the result of overflow ...
