How the ocean’s hydrothermal systems made the first life on Earth possible Researchers have discovered that chemical reactions in underwater hydrothermal vents could have produced the necessary ingredients for life on Earth.

Enhanced synthesis of fly ash-derived hydrated sodium silicate adsorbents via low-temperature alkaline hydrothermal treatment for advanced environmental applications

Scientists turn low‑cost #FlyAsh into #SodiumAluminosilicate via 1‑step #hydrothermal alkali dissolution, where alkali, temperature & time drive zeolite→calcite, enabling FA #valorization into porous adsorbents for environmental use.

Backcountry hot springs In the last few summers, I've been exploring some of Yellowstone's accessible backcountry thermal areas. This area is on the Trails Illustrated maps and an easy hike on a maintained trail. I'll let yo...

An easily-accessible #backcountry hot spring. Flat trail, 15-30 minutes from the car. I've never seen anyone else there.

Get off the boardwalks. Also, be safe.

A serene setting along the early trail among evergreens, concealing the 'hell' that awaits further along.

Looking out from the rocky outcrop that makes an early viewpoint towards what I believe is Pilot Pinnacle.

Various pools of turquoise or grey water with steam escaping from hydrothermal vents make up Bumpass Hell, an inhospitable landscape with the slight screaming sounds emanating all around it. A boardwalk cuts along the pools for viewing up close. Outside of the 'hell', evergreens grow in the corners of the frame.

A steaming and bubbling pool forms above a hydrothermal vent.

Hot Springs on the Snake This unnamed hydrothermal group has a half-dozen hot springs. Schneider calls it "extensive," while Bohannan calls it "extinct." The truth lies in between.

There are also a half-dozen undistinguished thermal features near this ford. Because I knew there was a large boar #grizzly over there, I didn't explore more closely.

Hydrothermal vents release hot, mineral-rich water, creating black smoker plumes 🌊. High-resolution simulations reveal complex near-seafloor turbulence & potential pathways for deep-sea life 🐚

A hydrothermal vent on the Mid-Atlantic Ridge. Hot, mineral-rich fluids are distributed throughout the ocean via the dispersion cloud, known as the plume. The photo was taken during the M190 research expedition with the MARUM-QUEST4000 remotely operated vehicle. The arm of the robot holds a temperature lance into the plume to measure the temperature there. Photo: MARUM – Center for Marine Environmental Sciences, University of Bremen.
