Peptide‐based antibacterial nanoplatforms: Design principles, stimuli‐regulated behaviors, and applications

Responsive Materials, EarlyView.
Peptide‐based antibacterial nanoplatforms, encompassing self‐assembled peptides and peptide‐engineered inorganic, polymeric, and lipid nanocarriers, are systematically reviewed. The article highlights design principles and stimuli‐responsive regulation for improving peptide stability, delivery efficiency, and antibacterial performance.

Membrane-spanning lipids for an uncompromised monitoring of membrane fusion and intermembrane lipid transfer

Journal of Lipid Research, 2015
A Förster resonance energy transfer-based fusion and transfer assay was developed to study, in model membranes, protein-mediated membrane fusion and intermembrane lipid transfer of fluorescent sphingolipid analogs.

The Polar Lipid Fraction E from Sulfolobus acidocaldarius Can Be Used as Liposomal Drug Stabilizing Agents to Reduce the Leakage of the Antivascular Drug Combretastatin A4 Disodium Phosphate from Tetraether/Diester Hybrid Archaeosomes

Biophysica, 2021
Liposomes have many advantages as therapeutic capsules over free drugs such as small molecule drugs and nucleic acids. Cholesterol is commonly used as a membrane stabilizing agent in liposomal drugs (e.g., mRNA-lipid nanoparticle COVID-19 vaccines ...

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).

Deglacial Permafrost Organic Carbon Delivery at the Northern Svalbard Continental Margin: Insights From Tetraether Lipids and Plant Biomarkers

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.

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 ...

Towards quantitative reconstruction of past monsoon precipitation based on tetraether membrane lipids in Chinese loess [PDF]

Climate of the Past
Variations in the oxygen isotope composition (δ18O) of cave speleothems and numerous proxy records from loess–paleosol sequences have revealed past variations in East Asian monsoon (EAM) intensity.

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.

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.
