Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.

Transposon mutagenesis give scientists a rare look at the most important interactions within microbial communities.

Multiple white tailed deer tested positive for SARS-CoV-2 likely transmitted from humans, a study finds, indicating the species could act as a reservoir for the virus.

Bacteria inhabit most tissues in the human body, and genes from some of these microbes have made their way to the human genome. Could this genetic transfer contribute to diseases such as cancer?

The University of St. Andrews behavioral ecologist studies the social structures and behaviors of whales and dolphins, recording and analyzing their acoustic communications.

Next-generation sequencing has identified scores of new microorganisms, but getting even abundant bacterial species to grow in the lab has proven challenging.

Clostridium difficile is evolving more robust toxicity, repeatedly attacking its victims, and driving the search for alternative therapies to fight the infection.

Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

So far, six animal species are known to carry transmissible, “parasitic” forms of cancer, but researchers are still mystified as to how cancer can become infectious.
