How tendons become stiffer and stronger

Tendons connect muscles to bones. They are relatively thin, but withstand enormous forces. Tendons need a certain elasticity to absorb high loads, such as mechanical shock, without tearing. In sports involving sprinting and jumping, however, stiff tendons are an advantage because they transmit the forces that unfold in the muscles more directly to the bones. […]

Study looks at how the human microbiome varies with location

Home is where the microbes are. That’s one takeaway from newly published research by an interdisciplinary University of Oregon team that found a shared home environment to be the strongest predictor of human microbiome similarity, or the commonalities between the communities of microbes that live within us. “Our results demonstrate that the early life home […]

How the body builds a healthy relationship with ‘good’ gut bacteria

But even the “good” can have bad effects if these bacteria end up in tissues and organs where they’re not supposed to be. Now, research published […]
