Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change
Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes
Advanced NanoBiomed Research, Volume 6, Issue 6, June 2026.Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract Degradation of Arctic permafrost due to global warming and sea level rise could trigger positive feedbacks, exacerbating climate change. However, uncertainties remain on how permafrost systems may respond because we lack a complete understanding of the permafrost‐climate feedback.

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.

Planktonic Lipidome Responses to Aeolian Dust Input in Low-Biomass Oligotrophic Marine Mesocosms
Frontiers in Marine Science, 2017 The effect and fate of dry atmospheric deposition on nutrient-starved plankton in the Eastern Mediterranean Sea (EMS; Crete, 2012) was tested by spiking oligotrophic surface seawater mesocosms (3 m3) with Saharan dust (SD; 1.6 g L−1; 23 nmol NOx mg−1; 2 ...

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 ...

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.

Assessment of soil n-alkane δD and branched tetraether membrane lipid distributions as tools for paleoelevation reconstruction [PDF]
Biogeosciences, 2009 δ18O values of pedogenic minerals forming from soil water are commonly used to reconstruct paleoelevation. To circumvent some of the disadvantages of this method, soil n-alkane δD values were recently proposed as a new tool to reconstruct ...

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.
