In textbooks, you'll find that certain iron-oxidizing bacteria are exclusively found in freshwater. But we've recovered their genomes from deep-sea hydrothermal vents! 🦠🤔
We've explored what they do, how they adapt to this environment, and whether we can determine their origins 🧬

**BIG NEWS in the geology world!** For the first time, scientists spotted an active eruption along the mid-ocean ridge!!

They visited the hydrothermal vent the day before, where a vibrant ecosystem thrived in the sweltering water. The next day, everything was gone. ⚒️🧪

My latest for @nytimes.com
Volcanic Eruption in Deep Ocean Ridge Is Witnessed by Scientists for First Time (Gift Article)
Researchers diving in a submersible in the eastern Pacific realized that the landscape they had studied the day before had been glassed over by fresh lava.
