Things We Don’t Know

Toxoplasmosis - the disease that makes you like cats - is asymptomatic in healthy adults, but can be devastating in unborn babies. But what are the risks of contracting it during pregnancy, and why do some women avoid eating their greens?

What happens to our bodies when we die? Devoured by microbes and insects, could this be a new forensic field crawling out of the woodwork?

What is nesting, and is it a real scientific concept? Can male and non-pregnant females nest as well as pregnant females, or is it all in our heads?

There are many unknowns when it comes to pregnancy, and many accepted phenomena are still unexplained, or simply attributed to "hormones" or "the placenta" (a complex and poorly understood organ!).

What is the placenta? This two-sided disc is complex and poorly understood. Scientists are still exploring how it grows and how it functions.

Is there a magnetic version of the jumper-balloon experiment - charging an object magnetically to make a magnetic monopole?
