How does lava sound when it comes to the surface of the Earth? Listen to a lava flow oozing out of its effusive vent high on the southwestern side of #Etna, 28 August 2025. That day no visits by tourists were allowed on the site, which permitted this (relatively) clean recording

Jones: I want to bring theology into this because you have all these people that want to give thoughts and prayers. But I was a minister, and that is a form of theological malpractice—when you pray for something you have the power to change.

I hope you enjoy it! I didn't pull any punches with the science, but I tried to make it fun. Maybe after you re-read all those books, you can watch The Core! www.youtube.com/watch?v=LVko...

Asgard archaea frozen in Siberia appear to have remained alive for more than 100,000 years based on DNA analysis. Genetic overlap with other Asgards suggests astonishingly long lifespans could be common trait among the closest living relatives of all eukaryotes. Per @karenlloyd.bsky.social etal.🧪

We are unlocking how frozen microbes stay alive for 100,000 years

Microbes found buried deep in Siberian permafrost may be able to survive over extremely long timescales using protein repair genes

Good question! There's just an insert of color photos of field work. As long as you can conjure images of a researcher bouncing down a volcanic scree pile, and doing a "happy dance" next to a drill and snowmobiles (we had a HARD time reaching permafrost), you can understand the book without them. :)

If you want, you can read MY book about it! It's called Intraterrestrials: Discovering the Strangest Life on Earth. (But I agree, it would be FIRE if @carlzimmer.com put his own spin on the subject!) press.princeton.edu/books/hardco...

Intraterrestrials

A biologist’s firsthand account of the hunt for life beneath earth’s surface—and how new discoveries are challenging our most basic assumptions about the nature of life on Earth

Sidebar: When I'm staring wistfully into the distance in these photos, what I was really doing was watching a great blue heron galumph around, awkwardly perching on things that were too small for it. That bird should hire itself out for future photo shoots.

Check this nice first first-author paper by Ning Hall—now out in Nature Geoscience! Our team had a blast supporting Ning on the isolation workflow, and a few of the standout Methanococcoides strains even trace back to our Danish waters. 🌊

Coastal methane emissions driven by aerotolerant methanogens using seaweed and seagrass metabolites - Nature Geoscience

Experiments suggest aerotolerant archaea produce methane in the surface layers of coastal sandy sediments and that this activity is driven by seaweed and seagrass metabolites.

Thanks, @jamesdinneen.bsky.social, for the lovely review of my book. I hope y'all have as much fun reading it as I did writing it!

@karenlloyd.bsky.social's new book Intraterrestrials offers the field guide to Earth's deep biosphere you didn't know you needed. Here's my review in @newscientist.com:

Yeh, that would be cool too! I don't think there's a precedent for that suffix, though.

This is a nice explanation of how SAR11, a starvation expert, tries to curl up and die when you feed it. This is why the best approach to getting these uncultured organisms to grow is often a sneak attack - feed them but don't feed them too much! @jcamthrash.bsky.social @ahoiching.bsky.social

Organisms that are buried alive for many thousands of years without enough energy to grow could be called "aeonophiles", so we can talk about them more easily. @drewsteen.bsky.social tinyurl.com/4tzecaxn
