From Asgard to Earth: Tiny Discoveries Hold Clues To Life’s Greatest Leap
Stromatolites – and their close relatives, microbial mats – could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of […]

Redox distribution Of Asgard Archaea And Co-occurring Taxa In Microbial Mats From An Early Proterozoic Ecosystem Analog
Eukaryotes originated from the symbiosis of an Asgard archaeon, the alphaproteobacterial ancestor of mitochondria, and possibly additional bacterial contributions.

The Phylogenetic Context For The Origin Of A Unique Purple-green Photosymbiosis
Symbioses are widespread in nature and have been the source of much evolutionary innovation. While some types of symbioses evolved multiple times across space and time (e.g., oxygenic photosymbioses or […]

Newly Discovered Hydrothermal Vents At Depths Of 3,000 Meters Off Svalbard
Hydrothermal vents are seeps on the sea floor from which hot liquids escape. “Water penetrates into the ocean floor where it is heated by magma. The overheated water then rises […]

Giant Deep-sea Vent Tubeworm Symbionts Use Two Carbon Fixation Pathways To Grow At Record Speeds
In the deep-sea environment of the East Pacific Rise, where sunlight does not penetrate and the surroundings are known for their extreme temperatures, skull-crushing pressures, and toxic compounds, lives Riftia […]

Symbiosis Study Exposes New Theories And Identify Experimental Systems For Plant Life On Earth
A Mississippi State faculty member’s work on plant life symbiosis—a mutually beneficial relationship between living organisms—is pushing back against the newer theory of “single-origin”—that all life stems from one point—instead […]
