Article Synopsis
- This study analyzes changes in pastoral practices in the Jerusalem region from Iron Age II to Late Hellenistic times using a multi-isotope approach on 135 animal samples.
- It reveals that most animals were locally sourced, but some came from distant regions, indicating established regional exchange networks.
- Findings suggest that during the Persian period, pastoral communities adapted to environmental changes with greater flexibility, while in the Late Hellenistic period, they faced restrictions that shifted grazing patterns and increased imports.
Clustered regularly interspaced short palindromic repeats (CRISPR)-Cas (CRISPR-associated proteins) systems provide acquired heritable protection to bacteria and archaea against selfish DNA elements, such as viruses. These systems must be tightly regulated because they can capture DNA fragments from foreign selfish elements, and also occasionally from self-chromosomes, resulting in autoimmunity. Most known species from the halophilic archaeal genus contain type I-B CRISPR-Cas systems, and the strongest hotspot for self-spacer acquisition by was a locus that contained a putative transposable element, as well as the gene , which was a very frequent target for self-targeting spacers.

Objectives: This study aimed to evaluate the impact of an online social media-based, health care professional-led, educational and support program on patients' long-term engagement with and adherence to follow-up guidelines, self-care recommendations, and weight management after bariatric surgery.
Methods: An observational cohort study, employing mixed methods, accompanied a 12-week interactive, structured, social media psychoeducational intervention program delivered on Facebook.
Reconstructing the absolute chronology of Jerusalem during the time it served as the Judahite Kingdom's capital is challenging due to its dense, still inhabited urban nature and the plateau shape of the radiocarbon calibration curve during part of this period. We present 103 radiocarbon dates from reliable archaeological contexts in five excavation areas of Iron Age Jerusalem, which tie between archaeology and biblical history. We exploit Jerusalem's rich past, including textual evidence and vast archaeological remains, to overcome difficult problems in radiocarbon dating, including establishing a detailed chronology within the long-calibrated ranges of the Hallstatt Plateau and recognizing short-lived regional offsets in atmospheric C concentrations.

- * The complexity of defining and measuring microcephaly varies between fetuses and newborns, leading to challenges in accurate diagnosis that could result in mismanagement, such as erroneous pregnancy terminations or unexpected birth of affected infants.
- * Advances in imaging and genetic testing, along with improved measurement techniques, could enhance the prediction and management of fetal microcephaly, and the article proposes an updated algorithm for better diagnosis and care.
