Purpose Of Review: This review examines Electronic Nicotine Delivery Systems (ENDS) use behavior during pregnancy, including the prevalence of and transitions in use during pregnancy.
Recent Findings: Twenty-two papers addressed the prevalence of and/or transitions in ENDS use during pregnancy. Findings show a complex landscape of ENDS use. A minority (0.4%-7.0%) of pregnant persons use ENDS; most commonly this occurs in the form of dual use (ENDS and combustible cigarettes (CC); 75%). Many pregnant persons report using ENDS because they perceive them to be a lower-risk alternative and/or potential cessation aide for CC smoking. However, while a subset of those who use ENDS do quit all tobacco product use during pregnancy, only a small proportion switch from exclusive CC smoking to exclusive ENDS use.
Summary: ENDS are a somewhat new addition to the tobacco product landscape. The perception of ENDS as a lower-risk alternative may contribute to ENDS use in pregnancy. There is insufficient evidence to support the notion that ENDS facilities the cessation of tobacco product use during pregnancy.

A self-opening transfer shuttle has been designed and fabricated for the transfer of air-sensitive samples to scanning electron microscopy (SEM). Delayed push out of an airtight sample cabin sealed inside the shuttle allows the protection of the sample from air exposure during the pumping of SEM chamber. A compressed spring is employed to automatically drive the push out of the cabin.

Alternative polyadenylation (APA) is an important driver of transcriptome diversity that generates messenger RNA isoforms with distinct 3' ends. The rapid development of single-cell and spatial transcriptomic technologies opened up new opportunities for exploring APA data to discover hidden cell subpopulations invisible in conventional gene expression analysis. However, conventional gene-level analysis tools are not fully applicable to APA data, and commonly used unsupervised dimensionality reduction methods often disregard experimentally derived annotations such as cell type identities.

Plastic waste that ends up in the deep sea is becoming an increasing concern. However, it remains unclear whether there is any microflora capable of degrading plastic within this vast ecosystem. In this study, we investigated the bacterial communities associated with different types of plastic-polyamide-nylon 4, 6 (PA), polyethylene (PE), polyethylene terephthalate (PET), and polystyrene (PS)-after one year of in situ incubation in the pelagic deep sea of the Western Pacific.
