The discovery of superconductivity in twisted bilayer and trilayer graphene has generated tremendous interest. The key feature of these systems is an interplay between interlayer coupling and a moiré superlattice that gives rise to low-energy flat bands with strong correlations. Flat bands can also be induced by moiré patterns in lattice-mismatched and/or twisted heterostructures of other two-dimensional materials, such as transition metal dichalcogenides (TMDs).

Article Synopsis
  • - The study explores the link between chronic kidney disease (CKD) and periodontal disease, proposing that changes in saliva and oral microbiota due to CKD could initiate periodontal disease rather than the other way around.
  • - Using animal models, researchers found that kidney disease led to a significant reduction in alveolar bone height and caused changes in salivary biochemistry and oral microbiota composition, resulting in a dysbiotic environment.
  • - Findings suggest that interactions between oral bacteria and the systemic conditions of CKD can exacerbate periodontal issues, as co-housing healthy rats with those having kidney disease improved periodontal health, while transferring diseased microbiota caused periodontal disease in healthy mice.

Bile acids are trans-genomic molecules arising from the concerted metabolism of the human host and the intestinal microbiota and are important for digestion, energy homeostasis and metabolic regulation. While diurnal variation has been demonstrated in the enterohepatic circulation and the gut microbiota, existing human data are poorly resolved, and the influence of the host circadian system has not been determined. Using entrained laboratory protocols, we demonstrate robust daily rhythms in the circulating bile acid pool in healthy male participants.
