Quantification of methyl glyoxal in New Zealand Mānuka honey and honey meads.

Mānuka honey is New Zealand's (NZ) most globally sought-after honey variety, due to the bioactive effects conferred by methyl glyoxal (MGO). Several NZ meaderies produce Mānuka mead, being a unique NZ product with significant marketing potential; however, it has not been explored in the scientific literature, and MGO has never been quantified in mead of any type. Thus, a versatile HPLC method for the quantification of MGO in both Mānuka mead and honey has been developed, optimised and validated.

Exposure to air pollution from coal-fired power plants and impacts on human health: a scoping review.

Communities living in proximity to coal-fired power plants (CFPPs) may be at greater risk of negative health impacts from exposure to air pollution than communities living further away. The aim of this scoping review was to provide an update on the evidence of the health risks of air pollution exposure associated with living in proximity to CFPPs and to evaluate the relationship between residential proximity and the extent of the health burden. We followed the PRISMA-ScR guidelines and searched Google Scholar, PubMed, ScienceDirect, Scopus and Web of Science for relevant studies from inception up to 31 January 2024.

Mead production and quality: A review of chemical and sensory mead quality evaluation with a focus on analytical methods.

Mead, an alcoholic beverage made from the fermentation of honey in water by yeast, has an expanding global market and popularity, and a concurrently broadening library of related scientific literature. Quality of mead can be evaluated using both sensory and physicochemical characteristics, with volatile aroma and phenolic profiles being of particular importance. Different mead-making techniques can have significant impact on these parameters and thus the overall mead quality.

Genome Assembly of a Living Fossil, the Atlantic Horseshoe Crab Limulus polyphemus, Reveals Lineage-Specific Whole-Genome Duplications, Transposable Element-Based Centromeres, and a ZW Sex Chromosome System.

Horseshoe crabs, considered living fossils with a stable morphotype spanning ∼445 million years, are evolutionarily, ecologically, and biomedically important species experiencing rapid population decline. Of the four extant species of horseshoe crabs, the Atlantic horseshoe crab, Limulus polyphemus, has become an essential component of the modern medicine toolkit. Here, we present the first chromosome-level genome assembly, and the most contiguous and complete assembly to date, for L.
