Navigating ethics in HIV data and biomaterial management within Black, African, and Caribbean communities in Canada.
BMC Med Ethics
January 2025
Klinic Community Health, Winnipeg, MB, Canada.
Background: This study explored the ethical issues associated with community-based HIV testing among African, Caribbean, and Black (ACB) populations in Canada, focusing on their perceptions of consent, privacy, and the management of HIV-related data and bio-samples.
Methods: A qualitative community-based participatory research (CBPR) approach was employed to actively engage ACB community members in shaping the research process. The design included in-depth qualitative interviews with 33 ACB community members in Manitoba, Canada.
Urban and rural residence: their influence on food group consumption in Iran.
BMC Public Health
January 2025
Metabolic Syndrome Research Center, Mashhad University of Medical Sciences, Mashhad, 99199-91766, Iran.
Background: Urbanization is expanding in Iran, leading to the emergence of three distinct socio-geographical areas: urban, rural, and suburban areas. These different areas may exhibit significant variations in dietary patterns. This study investigates the association between people's place of residence and their consumption of different food groups.

BMC Plant Biol
January 2025
College of Life Science, Henan Agricultural University, Zhengzhou, China.
Background: Assessing the current status and identifying the mechanisms threatening endangered plants are significant challenges and fundamental to biodiversity conservation, particularly for protecting Tertiary relict trees and plant species with extremely small populations (PSESP). Ulmus elongata (Ulmus, Ulmaceae) with high values for the ornamental application, is a Tertiary relict tree species and one of the members from PSESP in China. Currently, the wild populations of U.

Nature
January 2025
Department of Genetics, Trinity College Dublin, Dublin, Ireland.
Roman writers found the relative empowerment of Celtic women remarkable. In southern Britain, the Late Iron Age Durotriges tribe often buried women with substantial grave goods. Here we analyse 57 ancient genomes from Durotrigian burial sites and find an extended kin group centred around a single maternal lineage, with unrelated (presumably inward migrating) burials being predominantly male.

Nature
January 2025
Key Laboratory of Coastal Environment and Resources of Zhejiang Province, School of Engineering, Westlake University, Hangzhou, China.
The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.
