Scientists studying pathogens such as Chlamydia, Legionella, and Listeria get a master class in how to control the internal workings of mammalian cells.

Various microbes, including several human pathogens, hijack the cell’s skeleton, membranes, and protein-making machinery to make themselves at home.

A clinical trial finds that the anticoagulant apixaban, which has been prescribed to help COVID-19 patients recover, is ineffective and in rare instances dangerous.

In flies and mice, a viral protein increases the rate of energy use by heart cells. But it’s not yet clear if the finding applies to humans.

At 33, Dal Co had already founded her own microbial ecology lab at the University of Lausanne in Switzerland.

Bats that experience food shortages due to climate change and habitat loss end up roosting in urban settings, where they shed more of the deadly Hendra virus. 

Researchers find so-called integrons, previously known only in bacteria, in their distantly related microbial relatives. 

Mycobacterium leprae appeared to reprogram the animals’ livers to a state partially resembling early development, resulting in healthy organ growth.

The ability to activate different sets of genes has likely helped the chytrid fungus Batrachochytrium dendrobatidis spread widely in amphibians, resulting in global population declines. 

A high-fat diet induced changes to the animals’ vaginal microbiomes that boosted survival after exposure to the virus.

Cofounders of a microbiome biobank speak with The Scientist about their new partnership with nonprofit OpenBiome and how to ethically work with donors.

A jolt of norepinephrine in the mouse gut facilitates colonization by certain microbes, which in turn deplete glycine, enhancing cocaine-induced behaviors.
