What's That Rash?

We've all probably wished for a way to achieve our fitness goals without the strain and sweat that can come with exercise.
So what if you could lose weight, gain muscle and improve circulation just by standing on a vibrating platform?
Norman and Tegan buzz through the evidence for and against vibration plates and so called "passive exercise".

Snail slime, or snail mucin, has become a popular product in skin care.
Some claim it has anti-ageing properties, but if the early research shakes out, snail mucus could have even more significant uses.
Norman and Tegan discuss why snail gunk has become a hero of cosmetics, and what else it might be capable of.

What we do (and don't) know about tinnitus

Walking down the street, most people you pass will be wearing headphones or ear buds. Chances are you are too!
But is this trend of noise-cancelling harming your ears or the way your brain processes sound?
Norman and Tegan sound out the evidence on headphone use and hearing damage, and what you can do to protect your ears.

Many people believe that taking vitamin C supplements helps their immune system fight off colds.
But there are even bigger claims attached to this supplement – that it not only boosts immunity, but fights cancer.
Norman and Tegan introduce us to the Nobel laureate who pushed these theories decades ago, and whether there’s any truth to them.

Unless you're in certain corners of the internet, you won't be aware of the peptide craze promising to grow your muscles and slow ageing.
That's because your average GP won't be printing a prescription for these injectable drugs, like BPC-157 or melanotan.
Norman and Tegan discuss why there's so much fan fare over unproven peptides with some potentially nasty side effects.
