Regulatory RNAs play a central role in the regulation of gene expression and can act on several regulatory levels from transcriptional initiation and RNA processing to the control of initiation of translation and RNA stability. One class of these molecules is non-coding (nc)RNAs in bacteria that typically lack protein-coding potential, range in size between 50 and 500nt and originate from intergenic regions. Common methods for the identification of these RNAs are either based on computational predictions, or on transcriptomic analyses of laboratory cultures, whereas very little is known about ncRNAs in environmental microbial populations. Here, we have combined a metatranscriptomics approach with a selective enrichment protocol for ncRNAs. The primary objective of this study was the identification of novel, environmentally relevant ncRNAs focusing on the cyanobacterium Prochlorococcus, which was one of the dominant microorganisms of the marine community of the Gulf of Aqaba when samples were taken.

Organismal communities associated with coral reefs, particularly invertebrates and microbes, play crucial roles in ecosystem maintenance and coral health. Here, we characterized the organismal composition of a healthy, non-urbanized reef (Site A) and a degraded, urbanized reef (Site B) in the Gulf of Eilat/Aqaba, Red Sea to assess its impact on coral health and physiology. Biomimetically designed terracotta tiles were conditioned for 6 months at both sites, then reciprocally transplanted, and scleractinian coral species, Acropora eurystoma and Stylophora pistillata, were attached for an additional 6 months.

Coral reefs, despite covering less than 0.2 % of the ocean floor, harbor approximately 35 % of all known marine species, making their conservation critical. However, coral bleaching, exacerbated by climate change and phenomena such as El Niño, poses a significant threat to these ecosystems.

The global degradation of natural coral reefs requires innovative approaches to their conservation and restoration. This study investigates the efficacy of using parametric design tools in 3D software and 3D-printed terracotta structures in artificial reef (AR) design. Three ARs were deployed in the northern Gulf of Aqaba in 2019.
