Background And Purpose: MRI is crucial for multiple sclerosis (MS), but the relative value of portable ultra-low field MRI (pULF-MRI), a technology that holds promise for extending access to MRI, is unknown. We assessed white matter lesion (WML) detection on pULF-MRI compared to high-field MRI (HF-MRI), focusing on blinded assessments, assessor self-training, and multiplanar acquisitions.
Methods: Fifty-five adults with MS underwent pULF-MRI following their HF-MRI.
We present a comprehensive genetic investigation of Late Neolithic (LN) and Early Copper Age (ECA) populations living in the Carpathian Basin, leveraging whole genome data from 125 previously unreported individuals. Using population genetics, kinship analyses and the study of networks of identity-by-descent haplotype segment sharing, we elucidate the social and genetic dynamics of these communities between 4800-3900 cal BCE. Despite changes in settlement patterns, burial practices, and material culture, we document a high degree of genetic continuity.

- The study focuses on one-photon absorption and circular dichroism in three compounds: fenchone, camphor, and 3-methylcyclopentanone (3MCP).
- The results indicate that the transitions considered are weakly allowed, leading to significant anisotropies and necessitating the inclusion of non-Condon effects in theoretical models.
- Experimental data for 3MCP reveals that Herzberg-Teller corrections are essential to align theoretical predictions with observed features, underscoring the role of vibrational factors in electronic circular dichroism dynamics.
The ancient cemetery of Pommerœul, Belgium, was classified as Gallo-Roman in the 1970s', yielding 76 cremation graves and one inhumation. However, subsequent radiocarbon analyses dated the inhumation to the Late Neolithic (4-3 millennium calBC). We report osteoarchaeological analysis indicating that the inhumation was composed of bones from multiple individuals, afterwards buried as "one".

- Ancient DNA (aDNA) was analyzed from two skeletons found in the Jamestown church, believed to be related to the colony's first Governor, Thomas West.
- The genomic study identified a shared mitochondrial haplogroup (H10e), indicating a maternal connection between the two men, Sir Ferdinando Wenman and Captain William West.
- This investigation into their DNA also uncovered a hidden aspect of their identity—illegitimacy—that was likely left out of official genealogical records.
