151 – Scrambler Therapy: how good is it at treating chronic pain
A viewer question prompts Chris and Sophie to look into scrambler therapy. A medical therapy for chronic pain with a silly name that sounds like it should be pseudoscience, but actually isn’t. How is it different from Transcutaneous Electrical Nerve Stimulation (TENS)? How good is the evidence and how much of the benefit is actually a placebo response.

150 – How Scientific Skepticism Makes us More Empathetic
Rodney Schmaltz joins Chris to talk about teaching scientific skepticism to university students. How does learning about Big Foot, debunking photos of fairies, and going on a ghost hunt make you better at debunking pseudoscience?

148 – Transcranial Magnetic Stimulation
The opening of a new private clinic spurs Chris and Sophie to ask whether Transcranial Magnetic Stimulation (TMS) is real medicine or pseudoscience.

146 – Radon – the invisible houseguest
Chris and Sophie tackle Radon, the odorless, colorless, tasteless and very toxic gas that is present in about 1 in 5 homes. Why do we care? How do you test for it? What should do about it?

145 – Case Challenge: rare and common cardiac conditions
EPISODE 145 – Case Challenge: rare and common cardiac conditions Aigul returns with two new case challenges.

144 – Mommy Myths
Mommy forums are awash with medical misinformation.

143 – A possible diabetes cure using stem cells
Sophie joins Chris to unpack a new study about using stem cell derived cells transplanted into the pancreas of people with Type 1 diabetes. The early results showed 10 of the 12 patients who got the transplant no longer needed insulin. But the therapy comes with some risks because nothing in medicine is risk free. Is there a cure for a diabetes? Is it possible to treat diabetes without changing your diet? Listen to the episode to find out!
