Researchers repurpose tiny bacterial injection systems to specifically inject a wide variety of proteins into human cells and living mice.

Regulatory T cells in the colon travel to muscles to promote wound healing in mice, raising questions about how antibiotics may impact injury recovery.

Researchers find that bacteria stimulate a headache-causing pain pathway to suppress the immune system and infect the brain. 

Researchers identify hundreds of candidate histone proteins in bacteria, including one with an unusual way of binding to DNA.

A new microrobot uses algae to transport antibiotics into the lungs of mice with pneumonia.

Microscopic algae dotted with drug-filled nanoparticles may offer a more effective means of treatment than traditional delivery methods.

Researchers use blue light therapy to treat infected burn wounds.

A neural pathway between the gut and the brain led to the release of dopamine when the mice ran on a wheel or treadmill, but only in the presence of a robust microbiome. 

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.

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.

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