UK parliamentary inquiry reports in forensic science - Plus ça change?

Forensic Science provision in England and Wales underpins scientific evidence in many criminal cases. The quality of scientific investigation by scientists and the presentation of science insights has been under scrutiny and it is increasingly established that multiple significant, deep-rooted and persistent issues exist in the Forensic Science ecosystem. A thematic analysis of seven UK parliamentary inquiry reports that addressed Forensic Science and published since 2000, identified key themes and contextual factors.

Phase 2 randomized, dose-ranging trial of CTP-543, a selective Janus Kinase inhibitor, in moderate-to-severe alopecia areata.

Background: Janus kinase (JAK) activation is suggested to have a pathological role in alopecia areata (AA). CTP-543, a deuterated compound that selectively inhibits JAK1 and JAK2, is being developed as an oral treatment for AA.

Objective: To assess the safety and efficacy of a 24-week regimen of CTP-543 in patients with chronic, moderate-to-severe AA.

The Production and Evaluation of an Electrochemical Sensors for Strychnine and Its Main Metabolite Strychnine N-Oxide for Their Use in Biological Samples.

Strychnine (STN) and its major metabolite Strychnine N-Oxide (SNO) were examined electrochemically. Both parent compounds and its major metabolite showed electroactivity on glassy carbon electrodes using CV and DPV techniques. One oxidation peak at 1008 mV was observed for STN with the optimum peak intensity at pH 7.

The use of portable XRF as a forensic geoscience non-destructive trace evidence tool for environmental and criminal investigations.

Hand-held, portable X-Ray fluorescence instruments (pXRF) provide a means of rapid, in-situ chemical characterisation that has considerable application as a rapid trace evidence characterisation tool in forensic geoscience. This study presents both a control test study which demonstrates optimisation of the data collection process, alongside a range of individual forensic case studies, including heavy metal contamination, conflict archaeology, forensic soil characterisation, and verification of human remains, which together validate the technique and provide some comparison between field-based and laboratory-based pXRF applications. Results highlight the time-efficiency and cost-effectiveness of in-situ, field-based pXRF analyses for material characterisation when compared with other trace evidence methods.
