Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

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.

Chromium and Cobalt in Used Leather Items: A Danish Market Survey

Contact Dermatitis, EarlyView.
Used leather items from the Danish second‐hand market frequently release chromium(VI) and, in some cases, cobalt. Some items exceed current EU limits, highlighting a persistent but underrecognised source of exposure in the circular economy that may contribute to ongoing contact allergy despite existing regulations.

Gold and Nickel Release From Gold‐Plated Earrings Under Cysteine‐Modified Artificial Sweat Conditions

Contact Dermatitis, EarlyView.
Gold release from gold‐plated earrings was investigated using a cysteine‐modified artificial sweat solution designed to reflect biochemically relevant conditions. This model enabled detection of low‐level gold release. Nickel release was quantified in parallel and was detected in all samples, frequently exceeding established regulatory limits. ABSTRACT

Localised Autophagy Inhibition by Nanodiamonds Potentiates Arsenic Therapy With Favourable Safety Profile in Solid Tumours

Cell Proliferation, EarlyView.
This study presents an NDs‐mediated localised combination strategy that integrates autophagy inhibition with low‐dose ATO sensitization, enabling effective tumour suppression while enhancing safety. NDs‐mediated autophagy blockade enhances ATO efficacy while minimising systemic toxicity, highlighting a promising approach for solid tumour treatment ...
