Identification and significance of unsaturated archaeal tetraether lipids in marine sediments [PDF]

Rapid Communications in Mass Spectrometry, 2014
RATIONALE Studies of archaeal glycerol dibiphytanyl glycerol tetraethers (GDGTs) in the environment and cultures have exclusively focused on compounds with fully saturated alkyl moieties. Here we report a number of novel unsaturated GDGTs (uns‐GDGTs) whose alkyl chains contain up to six double bonds and zero to ...

Mitochondria‐Targeted Nanotherapeutics: A Promising Strategy in Modulating Mitochondrial Function, Transfer, and Transplantation

Advanced Science, Volume 13, Issue 58, 19 October 2026.
This review summarizes the pathogenic role of mitochondria in diseases and highlights mitochondrial transfer and transplantation as emerging therapeutic strategies. It systematically discusses how nanomaterials are engineered to facilitate these processes, and critically examines the current challenges and future perspectives for their clinical ...

Membrane lipids of mesophilic anaerobic bacteria thriving in peats have typical archaeal traits

, 2006
The 16S ribosomal DNA based distinction between the bacterial and archaeal domains of life is strongly supported by the membrane lipid composition of the two domains; Bacteria generally contain dialkyl glycerol diester lipids, whereas Archaea produce

Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]

, 2014
Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

Lipid hydrogen isotope compositions primarily reflect growth water in the model archaeon Sulfolobus acidocaldarius

Applied and Environmental Microbiology
The stable hydrogen isotope composition (δ2H) of lipid biomarkers can track environmental processes and remain stable over geologically relevant time scales, enabling studies of past climate, hydrology, and ecology.

Intratumoral Microbiota in Fueling Cancer and Steering Treatment Response

MedComm, Volume 7, Issue 10, October 2026.
Emerging research underscores the tumor‐specific colonization of microbiota and the role of intratumoral microbiota in cancer development and treatment resistance across multiple malignancies. Here, we provide a systematic review exploring the latest biotechnological advancements for studying low‐abundance intratumoral microbiota, their origins ...

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1644-1657, October 2026.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

The lysis mechanism of the haloarchaeal virus HFTV1

Cell Reports
Summary: Tailed bacteriophages can lyse their host with help of the holin-endolysin system. However, for archaeal tailed viruses (arTVs), whose archaeal hosts have a fundamentally different cell envelope, lysis mechanisms are unknown.

AllIGATR: A Multi‐Dimensional Approach for Marine Archaeal Lipid‐Based Paleothermometry

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract Archaeal glycerol dibiphytanyl glycerol tetraether membrane lipids (GDGTs) are ubiquitous in marine sediments. The number of ring structures in six specific GDGTs varies with seawater temperature, leading to their use in paleothermometry. GDGT temperature dependence is typically quantified in TEX86.
