Summary
It’s not a stretch to say that everyone suffers from unwanted body odor from time to time. Whether it’s stress, exercise, or heat, there are plenty of reasons why we sweat and there is a lot to learn about our bodies from the odors they create. To learn more about the science of body odor, Dr. Samantha Yammine is joined by Dr. Chris Callewaert, aka Dr. Armpit. Before that, Sam also digs into a new skin patch that might help out our friends with peanut allergies. Then, she explores a new theory into how the Black Death pandemic was able to spread so easily way back in the 1300s.

| 0:00.0 | Hey, curious minds, welcome back. We've got an exciting lineup this episode. First up, we'll discuss a recent clinical trial for a patch that can improve the lives of the many people living with peanut allergies if it gets approved. And then later, we'll explore a surprising theory. The volcanic eruption play a role in the spread of the black death? |
| 0:22.2 | And finally, as someone who's currently experimenting with my personal scent, I am very excited |
| 0:27.6 | about the guest who will be joining me later. Prepare for a unique conversation with none |
| 0:32.3 | other than Dr. Armpit. We're going to discuss an often ignored but never unnoticed topic body odor. |
| 0:39.5 | I'm Dr. Smith Yomene and this is Curiosity Weekly. |
| 0:44.2 | Chances are you know someone who has a peanut allergy. |
| 0:47.6 | Well, there's some encouraging news on the horizon. |
| 0:50.4 | In December 2025, DBV Technologies shared the successful results of its phase three trial for the Vyaskin peanut allergy patch. |
| 0:58.3 | Now, this is a comeback for the company, considering they faced a pretty tough step back five years ago when the FDA initially rejected the patch. |
| 1:05.7 | The trial involved 654 children between the ages of 4 and 7, making it one of the largest studies for peanut allergy |
| 1:12.5 | immunotherapy. Remarkably, nearly half of those with the Vyaskin patch could tolerate peanuts |
| 1:18.1 | after 12 months. That's compared to only about 15% in the placebo group. It doesn't mean they got |
| 1:23.8 | rid of the allergy, what they actually measured was how much more peanut exposure |
| 1:27.7 | the body could handle. But the difference in tolerance is encouraging. It could mean less of a risk |
| 1:33.0 | if you have an accidental exposure. In case you're wondering what happened the last time around, |
| 1:37.3 | let's quickly revisit some history. The Vyaskin patch was initially rejected back in 2020 |
| 1:41.9 | because the FDA said it needed some modifications so that it |
| 1:44.6 | would stick better to the skin, and they also called for more supporting data. And that wasn't |
| 1:48.9 | even their first attempt. They had previously withdrawn their application in 2018. And since then, |
| 1:54.2 | they've pressed on, and now with the success of their latest trial, they're gearing up to submit |
| 1:58.0 | a new application to the FDA in early 2026, aiming for |
| 2:02.0 | priority review. Peanut allergies are a significant public health concern, affecting like 1 to 2% |
