by Karen G. Lloyd — The story behind some extremely long-lived microbial cells.

Scientists once thought that life-sustaining oxygen existed only near Earth’s surface. Then they detected it deep underground.

Promethearchaeati are archaea with eukaryote-like genes, yet they live mainly in stable subsurface habitats. Their slow growth, fragile cells, and reliance on partners may explain why these traits are favored underground but not at Earth’s surface.

Karen G. Lloyd’s Intraterrestrials explores our planet’s “subsurface biosphere”: any environment below the ground or seabed untouched by sunlight, yet

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

A decade ago, Karen Lloyd discovered single-celled microbes living beneath the seafloor. Now she studies how they can survive in Earth’s crust, possibly for hundreds or thousands of years, and push li...

The landmark decision has been earmarked as a critical step in protecting the deep sea - recognised as the common heritage of humankind.

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.

Methane is a significant contributor to climate change (27 times more potent as a greenhouse gas than carbon dioxide), and the largest biological sink is methane-oxidizing bacteria: methanotrophs. Alt...

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.

Life thrives in the deepest, darkest recesses of Earth’s crust, and it is unlike anything seen on the surface. Discovered only in recent decades, intraterrestrials—bizarre subsurface being...
