Butter vs margarine: what's better for you?

The battle between butter and margarine has been happening since margarine was invented in the 19th century. So have we figured out which one is better for your health – butter with its high saturated fat content, or margarine which is an ultra-processed food? Norman and Tegan unpack the winding history of this debate from its inception to the present day.

Do you ever wonder while you’re shampooing and conditioning – is this really necessary? The no-poo movement encourages people to ditch their products and turn to homemade concoctions, or nothing at all.

It’s marathon season, but whether you’re running 40 kilometres or four you might’ve wondered what it’s doing to your joints. It used to be thought things like osteoarthritis of the knee or the hip were caused by wear and tear, and running made things worse.

Is loving your pets bad for you?

A post from Queensland Health has been ridiculed after for urging people not to kiss their pets or let them sleep in the same bed. So how do the risks of pet ownership stack up to the presumed benefits of having a furry (feathery or scaly) friend? Norman and Tegan take a look at the evidence – and some of its flaws – and reignite the age-old cat vs dog debate.
