More and more people who have never smoked tobacco are developing lung cancer. A new genomic analysis revealed that an accumulation of natural mutations led to the disease.
Regulatory T cells in the colon travel to muscles to promote wound healing in mice, raising questions about how antibiotics may impact injury recovery.
In humans, higher oxygen levels during ventilation are tied to an altered bacterial composition in the lungs, and mouse experiments show a causative link.
Making specific alterations to the bacterial population in a rat’s lungs either better protects the animals against multiple sclerosis–like symptoms or makes them more vulnerable, a study finds—the first demonstration of a lung-brain axis.
