Causes of Death and Physicians’ Knowledge‐Producing Responsibility—How Expectations Shape Interest in ‘Finding Out What Happened’

open access: yesSociology of Health &Illness, Volume 48, Issue 8, November 2026.
ABSTRACT Clinical knowledge production is fundamentally centred on patient problems, improving the lives of patients. If patients die, physicians also need to administer death. What is their responsibility to generate knowledge about causes of death? Based on semi‐structured interviews with 35 physicians, we show what sources physicians draw on, what ...

A Dual GC–MS and LC–MS/MS Analytical Strategy for Evaluating Free Chlorine Toxicity in Aqueous Samples

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Chlorine gas is a highly toxic industrial chemical that poses a significant risk in accidental releases and deliberate terrorist attacks. Reliable analytical methods for the determination of chlorine in aqueous samples are therefore required for forensic and environmental investigations.

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.

A Comparative Study of MALDI MSI Versus DESI MSI Applied to Questioned Document Examination

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale In forensic investigations, questioned document examination (QDE) provides critical information for document authentication and the detection of forgeries. Conventional QDE approaches often require separate analyses of inks and of any potential fingerprints.

Deer Antler δ18O Records Desalination in Israel's Water Supply

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Stable oxygen isotope ratios (δ¹⁸O) in mammalian tissues are widely used to reconstruct past climates, seasonal patterns, and animal origins. These analyses assume that animals drink local rainwater—an assumption now challenged by large‐scale anthropogenic water management.
