Is the Mother's Placenta Sterile?

There’s no place like “ome.” Your microbiome is highly influential in determining your health. But it’s not the only “ome” doing so. Your exposome – environmental exposure over a lifetime – also plays a role.

Hear how scientists hope to calculate your entire exposome, from food to air pollution to water contamination.

Plus, new research on the role that microbes play in the development of neurological diseases such as Parkinson’s, and the hot debate about when microbes first colonize the body. Could a fetus have its own microbiome?

Also, choose your friends wisely: studies of microbe-swapping gazelles reveal the benefits – and the downsides – of being social.

And, why sensors on future toilets will let you do microbiome analysis with every flush.
