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 ...

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

Geostandards and Geoanalytical Research, EarlyView.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.

Reconfiguring biofortification strategies to transform food systems and address micronutrient deficiency of the 21st century

Journal of Integrative Plant Biology, EarlyView.
This review explores how to make staple foods and horticultural crops more nutritious, including how artificial intelligence‐based screening of gene banks helps deploy nutritionally rich germplasm into breeding. Genome editing can help develop crops richer in minerals, vitamins, and health‐promoting compounds, supporting healthier diets and more ...
