Lifespan‐Extending Endogenous Metabolites

Aging Cell, Volume 25, Issue 2, February 2026.
Endogenous metabolites act as mediators of longevity by modulating conserved cellular pathways. We summarize mechanistic evidence linking specific metabolites to lifespan and healthspan benefits across model systems, with discussion of clinical evidence, translational opportunities, and remaining knowledge gaps.

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition

New Phytologist, Volume 249, Issue 4, Page 1699-1708, February 2026.
Summary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...

Zweikanal‐Fluoreszenz‐Assays mit supramolekularen Wirt/Farbstoff‐Reporterpaaren zur Kartierung der Membranaktivität von Peptiden

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Membranaktive Peptide (MAPs) wie zellpenetrierende Peptide (CPPs) und antimikrobielle Peptide (AMPs) können Lipidmembranen durchdringen und Membranporen bilden. Die Kombination aus einem Farbstoff‐Efflux‐Assay und einem supramolekularen Tandem‐Membran‐Assay in einem Zweikanalformat ermöglicht eine fortgeschrittene mechanistische Charakterisierung und ...

Dual‐Channel Fluorescence Assays with Supramolecular Host‐Dye Reporter Pairs for Membrane Activity Mapping of Peptides

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Membrane‐active peptides (MAPs) such as cell‐penetrating peptides (CPPs) and antimicrobial peptides (AMPs) can translocate across lipid membranes and create membrane pores. The combination of a dye efflux and a supramolecular tandem membrane assay in a dual‐channel format enables an advanced mechanistic characterization and an exploration of the ...
