Catch The Naked Scientist live in 702 Joburg studio on Thursday

The Naked Scientist

He talked about new cutting-edge blood tests that diagnose early cancer...

The Naked Scientist

Can a man experience pregnancy symptoms when their partner is pregnant, asked listeners?

Smith says there is evidence that men's behaviour and biochemistry does change. His hormone profile changes when his wife is pregnant and also once she has had children, he adds.

So a man who becomes a father often has quite different behaviour, and there is an evolutionary advantage to this because you want to be nurturing and protective towards offspring, you want to make sure they are ok.

The Naked Scientist

And why does one armpit sometimes get more sweaty...?

We have sweat glands which are eccrine and apocrine glands under the skin, they filter out plasma from blood putting down ducts, the ducts from these sweat glands open onto the skin surface and apply a thin film of sweat there and these other chemicals including, the things that make you smelly.
