What if it's not just our genes or our lifestyle, exactly, that makes us skinny or fat, healthy or sick? What if it's also the makeup of the bacterial ecosystem that inhabits our gut?

The scientists have found that all those pieces of plastic have provided ample opportunity for insects called "sea skaters" to breed.
