Discovery, structure and mechanism of a tetraether lipid synthase. [PDF]
Nature, 2022 Abstract Archaea synthesize isoprenoid-based ether-linked membrane lipids, which enable them to withstand extreme environmental conditions, such as high temperatures, high salinity, and low or high pH values 1–5 .

Molecular dynamics study of bipolar tetraether lipid membranes. [PDF]
Biophys J, 2005 Membranes composed of bipolar tetraether lipids have been studied by a series of 25-ns molecular dynamics simulations to understand the microscopic structure and dynamics as well as membrane area elasticity. By comparing macrocyclic and acyclic tetraether and diether archaeal lipids, the effect of tail linkage of the two phytanyl-chained lipids on the ...

On physical properties of tetraether lipid membranes: effects of cyclopentane rings. [PDF]
Archaea, 2012 This paper reviews the recent findings related to the physical properties of tetraether lipid membranes, with special attention to the effects of the number, position, and configuration of cyclopentane rings on membrane properties. We discuss the findings obtained from liposomes and monolayers, composed of naturally occurring archaeal tetraether lipids

Planktonic Archaeal Ether Lipid Origins in Surface Waters of the North Pacific Subtropical Gyre
Frontiers in Microbiology, 2021 Thaumarchaeota and Thermoplasmatota are the most abundant planktonic archaea in the sea. Thaumarchaeota contain tetraether lipids as their major membrane lipids, but the lipid composition of uncultured planktonic Thermoplasmatota representatives remains ...

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
Geophysical Monograph Series, Page 83-102., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Functionalized Membrane Domains: An Ancestral Feature of Archaea?
Frontiers in Microbiology, 2020 Bacteria and Eukarya organize their plasma membrane spatially into domains of distinct functions. Due to the uniqueness of their lipids, membrane functionalization in Archaea remains a debated area. A novel membrane ultrastructure predicts that monolayer

Structure-function relationships in pure archaeal bipolar tetraether lipids. [PDF]
Chem Sci, 2023 A series of archaeal bipolar glycerol dialkyl glycerol tetraether (GDGT) lipids were synthesized. Structural properties of self-assembled structures of GDGTs were studied and related to functional behavior such as membrane fusion.

Temperate Oligocene surface ocean conditions offshore of Cape Adare, Ross Sea, Antarctica [PDF]
Climate of the Past, 2021 Antarctic continental ice masses fluctuated considerably during the Oligocene “coolhouse”, at elevated atmospheric CO2 concentrations of ∼600–800 ppm. To assess the role of the ocean in the Oligocene ice sheet variability, reconstruction of past ocean ...
