Subduction zones vs mid-ocean ridge vents

42:48this paper. >> Yes. Yeah. I think I think it's very cool. the the core concept of is is life is constantly like evolving in places that we never thought was possible. >> This one is happening near the Mariana's trench and it's very different from the deep sea thermal vents that you were just alluding to actually. Okay, perfect. Okay. Because the deep sea thermal vents usually happen at places where the oceanic crust is diverging >> like in the middle mid-Atlantic ridge where there's a there's the crusts are like splitting apart. So there's a lot of volcanic activity happening. Right. Right there. >> Yep. >> Um and so there's a lot of like sulfur

43:28gas and all sorts of stuff coming out and then all of the bacteria are are capitalizing on that. This one is a subduction zone. >> Okay. Okay. The Mariana's Trench is something where where one plate is going under another rather than two splates splitting. Two plates splitting. >> Right. In the Mid-Atlantic Ridge, they're splitting. Here, one is going under another, right? >> Mhm. >> So, so it's a little bit different. And I think that's what's really cool. So, life is constantly trying to redefine boundaries, right? We've got extreopiles everywhere. Yellowstone, the the life in the hot springs. That's something that's in every single biology textbook. You've

44:09got hypers saline ponds in the Atakama desert that somehow managed to have bacteria. You've even got like nuclear reactor cores of power plants. >> They've got weird bacteria. >> That's interesting. >> And I want to cover that in another future episode because those things are very cool. this new paper, it's a landmark 2025 paper and it provides biomarker evidence for serpentine chemosynthetic biosphere. Okay, in the Mariana's Trench. So the setting is something called the Mariana for arc right under Japan east of the Philippines is the Mariana's
