A simple method to dramatically increase C. elegans germline microinjection efficiency

In this bioRxiv manuscript, Gibney et al., (2023) describe a paintbrush based method to improve the speed and survival of microinjections in C. elegans. The authors show a significantly higher injection efficiency when using a paintbrush instead of a pick to transfer worms to and from the agarose pad. The technique is simple as demonstrated in their videos.

Use of nematodes to study evolutionary biology

Nematodes have been used as model organisms for evolutionary studies. This article highlights the key findings from research on developmental processes, sex determination, dauer formation, vulva development, male tail formation and developmental regulation of gene expression with regards to evolution. An updated phylogenetic tree of the phylum Nematoda is also provided. This article is an excellent read to summarise evolutionary differences within nematodes for the above mentioned processes.

C. elegans provide milk to their offsprings through their decomposing bodies

Boroweic et al. (2020) describes the phenomena in which decaying bodies of older C. elegans turn into nutritious fluid for their offsprings using the insulin/IGF-1 insulin pathway.
