When did coffee get into our mouths? Who’s right when it comes to the best coffee? What’s the most ethical way to enjoy it? What about the cats that eat the beans? How will climate change affect your morning coffee? Peter Giuliano is the executive director of the Coffee Science Foundation explains folk stories behind coffee, what makes beans taste the way they do, why cold brew and nitro feel like rocket fuel, shade-grown coffee, roasting chemistry, flimflam, atmospheric pressure, dead espresso, and the best way to brew it, in his opinion. Also: why it tastes better outside – for some of us.

The Male Room with Dr. Jesse Mills

The Male Room with Dr. Jesse Mills

As Director of The Men’s Clinic at UCLA, Dr. Jesse Mills has spent his career helping men understand their bodies, their hormones, and their health. Now he’s bringing that expertise to The Male Room — a podcast where data-driven medicine meets common sense. Each episode separates fact from hype, science from snake oil, and gives men the tools to live longer, stronger, and happier lives. With candor, humor, and real-world experience from the exam room and the operating room, Dr. Mills breaks down the latest health headlines, dissects trends, and explains what actually works — and what doesn’t. Smart, straightforward, and entertaining, The Male Room is the show that helps men take charge of their health without the jargon.
