The finding that a bacterium within a bacterium within an animal cell cooperates with the host on a biosynthetic pathway suggests the endosymbiont is, practically speaking, an organelle.

After a scientist at the National Microbiology Laboratory in Winnipeg had a mental breakdown that may have contributed to her death in 2016, employees raise red flags about an unhealthy work environment.

The diurnal cycles of the microbiome alter the activity of a protein produced by the host, and in turn guide histone acetylation, gene expression, and metabolic activity.

Bacteria grow and divide in microfluidic channels.

Research on hundreds of babies finds the delivery method is linked with a greater abundance of taxa more frequently seen in hospitals.

Antibiotics disrupt the immune response to the influenza vaccine in people who haven’t recently had exposure to the virus or immunization.

A program to encourage transdisciplinary research at top cancer centers has evolved into a counterproductive national strategy for organizing cancer research.

Scientists cultivate sulfate-reducing microbes from some of the oldest-known water on Earth.

Scientists extracted 4,500-year-old yeast from Egyptian pottery to use in breadmaking.

Researchers confirm TR4’s presence in Colombia, increasing concerns about the future of the industry.

Oxytetracycline, approved by the US government to combat citrus scourge, may not work—at least not as a spray.

Physical activity, independent of diet, shifts the composition of bacteria in the intestines, spurring researchers to search for species that might provide benefits akin to working out.
