, crucial proteins in the placenta if you knock out that gene, they can't have kids. it just doesn't work. just recently viruses were also har necessaried for mustle, basically appear to be generated from a virus gene. that's good. there was then finally immunity over them, harness a couple of the gene and went on from there. our good and bad doesn't capture the strangeness of the little things. >> some scientists that think that some viruses might play a role in the immune system. we have loads of them in our bodies and some along the lining and the mucus, there are millions, trillions perhaps of the viruses stuck in the mucus waiting to infect bacteria and helps keep the population of microbes that live within us under check and help to collect for the species within us. you know, i think it also highlights another aspect to this work that we need to keep these populations and the balance of those communities matter. many of the diseases about zika and ebola, one microbe and one disease, you can also get illness when communities of microbes shift and no particular m

. >> some of these chemicals we know can cross the placenta and enter the womb and have effectcts at incredibly tiny, tiny doses. >> about 10 years ago, a seminal study was done on 10 newborns' cord blood. the cord blood, as the baby was born, contained several hundred toxic elements. which terrified all of us. >> chemimicals like e bisphenol, many different classes of flame retardants. >> we found ddt and pcbs, polychlorinated biphenyls. chemicals that we interact with every day fromom consumer products. >> we now know that along with the nutrients and d oxygen that thee mother supplies the developing baby y comes a cocktail of ttoxic chemicals.
