Influence of Growing Season Length on Orbital‐Scale Temperature Evolution Across the Chinese Loess Plateau

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Insight in the spatial evolution of absolute land temperature is crucial for understanding the dynamics of East Asian Summer Monsoon (EASM) precipitation, which governs the water supply for over 20% of the global population. The spatiotemporal evolution of land surface temperatures in East Asia is however not well documented.

Perspectives for Advancing Biotechnological Succinic Acid Production

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
Succinic acid is an important molecule for sustainable chemical manufacturing, but its industrial production faces high costs and sustainability challenges, which are linked to feedstocks and excessive acid/base consumption. This opinion explores production routes based on next‐generation feedstocks and low‐pH fermentations to inspire novel cost ...

Depth-related distribution of a key gene of the tetraether lipid biosynthetic pathway in marine Thaumarchaeota [PDF]

, 2014
The distribution of isoprenoid glycerol dialkyl glycerol tetraethers (GDGT) lipids synthesized by Thaumarchaeota has been shown to be temperature-dependent in world oceans.

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

Effects of a short-term experimental microclimate warming on the abundance and distribution of branched GDGTs in a French peatland [PDF]

, 2013
International audienceBranched glycerol dialkyl glycerol tetraethers (GDGTs) are complex lipids of high molecular weight, recently discovered in soils and increasingly used as palaeoclimate proxies.

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

Advanced Healthcare Materials, Volume 15, Issue 15, 17 April 2026.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Membrane lipid and expression responses of Saccharolobus islandicus REY15A to acid and cold stress

Frontiers in Microbiology, 2023
Archaea adjust the number of cyclopentane rings in their glycerol dibiphytanyl glycerol tetraether (GDGT) membrane lipids as a homeostatic response to environmental stressors such as temperature, pH, and energy availability shifts.

Environmental Controls on Crenarchaeol Distributions in Hydrothermal Springs [PDF]

Environ Microbiol
The optimal pH and temperature for crenarchaeol (a unique archaeal lipid) production in hydrothermal springs are 7.4°C and 46°C, respectively, which has important implications for archaeal evolution. Our study also indicates that pH is the most important environmental variable for archaeal lipid membrane compositions.

A mineralogical and organic geochemical overview of the effects of Holocene changes in Amazon River flow on three floodplain lakes [PDF]

, 2014
A synthesis of the impacts of the Amazon River hydrological changes on the sedimentation process of organic matter (OM) in three different floodplain lakes (Santa Ninha, Maracá, and Comprido lakes) is presented in this study.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.
