Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Molecular dynamics simulations and fluorescence spectroscopy suggest reduced tryptophan‐to‐heme energy transfer facilitates lignin degradation in ClassII peroxidases

The FEBS Journal, EarlyView.
In lignin peroxidase and versatile peroxidase, low FRET from buried Trp to heme promotes long‐range electron transfer (LRET) from substrate to heme. This efficient electron flow is facilitated by reduced FRET competition. This mechanism likely evolved to enable the effective degradation of bulky, high‐redox‐potential lignin that cannot reach the enzyme'

In Situ Colloidal Activated Carbon for PFAS Remediation in Groundwater: Principles, Performance Expectations, and Lessons from the First Decade

Groundwater Monitoring &Remediation, EarlyView.
Abstract Injectable colloidal activated carbon (CAC) has been commercially used to remediate per and polyfluoroalkyl substances (PFAS) in groundwater since 2016. The basis of the technology is enhanced PFAS retention within the aquifer from engineered increases in aquifer‐matrix sorptivity (“PFAS enhanced retention”), with re‐equilibration from the ...

The Effects of Canning on the In Vitro Solubility of Phosphorus in Pet Food

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Excess phosphate (P) intake through inorganic P (Pi) addition is known to cause various adverse health effects while declaration of use and amount in pet food in the EU is not regulated. Distinction between organic phosphate (oP) from feed ingredients and Pi with standard laboratory methods is impossible.
