New science is revealing breasts in a way that we’ve never seen them before. For years we’ve been seeking perfection: shape, size, and food source for our children. But now some scientists believe they may also be a hidden toxic waste ground. Putting breasts tissue - and breast milk - to the test, this documentary will investigate if these wonderful life-giving organs are under threat from the modern world and if they’re actually an early warning system telling us about the dangers of the chemicals around us.

One in three children, claim many tabloids, may not be biologically related to the man they call Dad. Could this really be true? This program conducts the first ever purpose-designed paternity poll, asking some truly awkward questions. Comparing rates of paternity uncertainty in Australia and the United States, we ask what is the real rate of ‘non-paternity’, and might there be biological survival benefits for children born outside marriage? Following parents and children as they seek to uncover the truth, we discover how, today, there’s nowhere to hide your genes.
