Electrochemical reduction technology is a promising method for addressing the persistent contamination of groundwater by chlorinated hydrocarbons. Current research shows that electrochemical reductive dechlorination primarily relies on direct electron transfer (DET) and active hydrogen (H) mediated indirect electron transfer processes, thereby achieving efficient dechlorination and detoxification. This paper explores the influence of the molecular charge structure of chlorinated hydrocarbons, including chlorolefin, chloroalkanes, chlorinated aromatic hydrocarbons, and chloro-carboxylic acid, on reductive dechlorination from the perspective of molecular electrostatic potential and local electron affinity.

Recent advances in acute myeloid leukemia (AML) come from studies investigating younger (age<60 years) adults or older (age≥75 years) or less fit adults. Uncertainty exists for the management of otherwise healthy adults with AML in their 60s and 70s, which also represents a significant proportion of AML cases. We discuss current considerations in older, fit adults with AML including determination of fitness, what factors beyond fitness should be assessed, and finally what challenges and innovations lie ahead to improve outcomes for these patients.

Banded iron formations (BIFs), significant iron ore deposits formed approximately 2.3 billion years ago under low-oxygen conditions, have recently gained attention as potential geological sources for evaluating hydrogen (H₂) production. BIFs are characterized by high concentrations of iron oxide (20 to 40 wt.

Different societal, systemic and personal barriers exist at various stages along a female researcher's career that can potentially undermine their success. The equation for women to reach higher positions in STEM is a multivariable one, and while there has been considerable progress towards addressing some of these compared with the past, current solutions are inadequate and do not address all facets. Here, we asked female winners of the FEBS Open Bio poster prize about their experiences regarding barriers they have faced at the predoctoral and postdoctoral stages, their opinions on how these can be addressed and their advice to new students entering a PhD degree.

Importance: Two meta-analyses published in 2012 found breech presentation, family history of developmental dysplasia of the hip (DDH), female sex, and primiparity to increase the risk of DDH. However, the DDH definition, reference tests, and the age of the examined children varied considerably, complicating the translation of those findings to current screening guidelines.
Objective: To evaluate the association of previously proposed risk factors with the risk of sonography-verified DDH.
