The largest metagenomic search for antibiotic resistance genes in the DNA sequences of microbial communities from around the globe has found that bacteria carrying those vexing genes turn up everywhere in nature that scientists look for them. The findings reported in the Cell Press journal Current Biology on May 8 add to evidence showing just how common and abundant those resistance genes really are in natural environments.

In a surprising new finding, researchers have discovered that bacterial movement is impeded in flowing water, enhancing the likelihood that the microbes will attach to surfaces. The new work could have implications for the study of marine ecosystems, and for our understanding of how infections take hold in medical devices.

People living in cold, northern latitudes have bacteria in their guts that may predispose them to obesity, according to a new study by researchers at the University of California, Berkeley, and the University of Arizona, Tucson. The types of microbes that live in the human gut vary with latitude. People in northern climes have more obesity-related bacteria than do people living farther south.

A team of researchers led by Virginia Tech and University of California, Berkeley, scientists has discovered that a regulatory process that turns on photosynthesis in plants at daybreak likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available.

A team of researchers from McMaster and the University of Concepción are shining a light on rare sulfur-loving microbes off the coast of Chile. The group's work near coastal fault lines has identified a previously unknown type of molecule, macplocimine A, which produces valuable natural chemicals that are known to function as effective cancer therapies and antibiotics.

Researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts have identified how one type of bacteria, Yersinia, immobilizes the immune system in order to grow in the organs of mice. To do so, the researchers extended the use of a technique and suggest that it could be used to study other bacteria that use the same or similar means of infection. The study is published in the September 11 issue of Cell Host & Microbe.
