    Is red light therapy real or a scam?

    17/09/2026 | 47 mins.
    Can shining a red light on your face really improve acne, wrinkles, inflammation, or wound healing, or is red light therapy just an expensive skincare scam involving a slightly alarming mask? How could ordinary visible light affect cells beneath your skin, and should you trust the products filling your social media feed? Melissa and Jam investigate photobiomodulation, mitochondria, collagen, blue light, FDA clearance, and the research behind this increasingly popular wellness trend. The answer is more scientifically interesting, and more complicated, than either of them expected.

    Which chemistry lessons have stuck with us? (Happy Chemiversary!)

    03/09/2026 | 1h 14 mins.
    What happens when a chemist and a non-chemist make a podcast together for seven years? Which chemistry lessons stuck, which episode ideas spectacularly refused to cooperate, and does Jam still count as a layperson after all this time? Joined by returning guest Claire, Melissa and Jam celebrate the seventh anniversary of Chemistry For Your Life with listener questions, behind-the-scenes stories, friendship reflections, favorite science facts, and one very large chemistry cookie cake. Come for the chemiversary; stay for the long-running argument about reality TV.

    Can water air-condition your house?

    27/08/2026 | 31 mins.
    What exactly is a swamp cooler, and why can it beat the heat in Arizona but leave you sweaty and betrayed in Houston? How can an air conditioner run on water, what does humidity have to do with its effectiveness, and could an icy new invention help prevent overloaded power grids? In the final installment of our air-conditioning series, Melissa and Jam explore evaporative cooling, ancient climate-control tricks, and some promising innovations for a hotter world. It turns out “It’s not the heat, it’s the humidity” is more scientifically accurate, and more annoying, than we’d like.

    What’s the dark side of air conditioning?

    20/08/2026 | 53 mins.
    Could a cheaper, more environmentally friendly refrigerant already exist, and could corporate lobbying be helping keep it out of American air conditioners? Why did the chemicals once hailed as safe alternatives become environmental villains, and are their replacements actually much better? Melissa and Jam follow the twisty history of Freon, ozone depletion, greenhouse gases, propane, and air-conditioning regulations to find out why choosing a refrigerant is never as simple as “this one works.” Grab your red string and conspiracy board, because the chemistry drama is heating up.
