Summary: In a study of 17,000 Medicare beneficiaries with mild cognitive impairment or dementia, it was found that non-Hispanic white older adults were more likely to have elevated cortical amyloid compared to Asian, Black, or Hispanic older adults, as measured by PET. These findings have important implications for the use of amyloid-targeting therapies.

Summary: Exposure to asbestos and asbestos-like minerals is associated with severe lung diseases. The study investigated the toxicity and cellular effects of fibrous antigorites on murine macrophages and alveolar epithelial cells. The findings revealed significant cellular toxicity of fibrous antigorites, which correlated with their fibrous habit and surface reactivity.

Summary: The NLRP10 protein forms an inflammasome complex in response to mitochondrial damage. The loss of NLRP10 in colonic epithelia promotes inflammatory bowel disease in a mouse model, while a variant associated with atopic dermatitis also exhibits loss of function.

Summary: The study aimed to test the hypothesis of island-hopping for the origin of old lineages of cockroaches in New Caledonia. The results suggest that indirect dispersal from Australia or New Zealand through now disappeared islands may explain the presence of these old groups in NC.

Summary: The study analyzed the clinical and microbiological features of Corynebacterium diphtheriae isolates in New Caledonia. The majority of isolates were from cutaneous sources and were associated with Staphylococcus aureus and/or Streptococcus pyogenes. Toxigenic isolates were observed in patients returning from Vanuatu. The isolates showed susceptibility to commonly used antibiotics. The study highlights the importance of diphtheria surveillance and improving immunization in neighboring islands.

Summary: Twenty-four new species and two new genera of Eutegaeoidea from Australia and New Caledonia are described in this study. These species have strong Gondwanan affinities and differ from the closely related Cepheoidea. The taxonomy of Eutegaeoidea is revised, and new distribution records are provided for previously described species. The study also establishes new families and reclassifies certain species within the group. A key to the genera of Eutegaeoidea is provided.

Summary: Recent expeditions to Rapa Nui and New Caledonia have discovered undescribed species from mesophotic and deeper depths, including new species, genera, and synonyms. Morphology and phylogenetic analysis support the placement of Goniaster among Asterodiscididae and propose biogeographic relationships among asterodiscidid genera.

Summary: We used a network of seismometers near Noumea, the capital city of New Caledonia, to record and analyze earthquakes for 14 months. The earthquakes in southern New Caledonia are smaller but more hazardous due to their shallow depths and proximity to local communities. Our study highlights the need for long-term monitoring of local earthquakes in this region and suggests that current models overestimate the hazard from large earthquakes in nearby subduction zones. Further research is needed to improve ground motion prediction in subduction zone footwall settings.

Summary: Ulva is a green macroalgal genus with rich species diversity and worldwide distribution. This study focused on the diversity of Ulva species in New Caledonia, a tropical region. The researchers collected specimens and used various methods to assess the species diversity, identify new species, and reconstruct the phylogeny of the genus. They found multiple Ulva species, including some bloom-forming ones, highlighting the importance of regulating water quality in areas exposed to strong nutrient input.

Summary: The study indicates that annual mean rainfall over New Caledonia may decrease by 18% by 2080-2100, with a significant reduction during the hot season. This drying trend is mainly driven by circulation changes, including strong anti-cyclonic and air subsidence anomalies reducing moisture convergence over the archipelago.

Summary: New Caledonia's history is influenced by deep marine sedimentation and tectonic evidence, with some deeply-diverging clades present before the Eocene. Fossil data are crucial for understanding the biota's history in New Caledonia.

Summary: Parkinson's disease is a progressive and debilitating disorder with neuroinflammation playing a role in its pathophysiology. Research into the neuroinflammatory processes of Parkinson's disease is ongoing, with many unanswered questions still remaining to be explored for the development of effective treatments.
