The investigation of triggers causing the onset and intensification of Northern Hemisphere Glaciation (NHG) during the late Pliocene is essential for understanding the global climate system, with important implications for projecting future climate changes. Despite their critical roles in the global climate system, influences of land-ocean interactions on high-latitude ice sheets remain largely unexplored. Here, we present a high-resolution Asian dust record from Ocean Drilling Program Site 1208 in the North Pacific, which lies along the main route of the westerlies.

Conservation efforts should focus on genetic variability within wild populations when considering reintroduction attempts. We studied two groups of lions from two conservation sites located in Zambia and Zimbabwe to determine their genetic make-up, information that is usually unknown to the sites.

- The study investigates how health behaviors like smoking, physical inactivity, and alcohol use may mediate the relationship between depression, anxiety, and different types of cancer, including lung and breast cancer.
- Utilizing data from 18 cohorts with a total of 319,613 participants, the researchers performed two-stage meta-analyses to analyze these associations and calculate the mediating effects.
- Results showed that smoking and physical inactivity significantly mediated links between depression, anxiety, and lung cancer, highlighting the importance of smoking cessation programs for individuals dealing with mental health issues.
Article Synopsis
- The Pre-Pottery Neolithic site of Aşıklı Höyük, occupied roughly 10,300 to 9,300 years ago in Central Anatolia, is associated with the early domestication of sheep, transitioning from residential stabling to open pasturing over time.
- Genetic analysis of 629 mitochondrial genomes revealed unexpected high genetic diversity during occupation, contradicting the earlier assumption of a domestication bottleneck.
- A significant demographic bottleneck was instead identified later in the Neolithic, leading to the dominance of a specific mitochondrial haplogroup in southwestern Anatolia that influenced sheep populations in Europe and today’s global sheep diversity.
Article Synopsis
- The study investigates the role of psychosocial factors, like depression and anxiety, in how health behaviors (such as smoking and alcohol use) influence cancer incidence.
- Utilizing data from 437,827 participants and 22 cohorts, researchers performed meta-analyses to assess potential interactions between psychosocial factors and health behaviors across various types of cancer.
- Results showed no significant interactions or clear patterns; the risk of cancer linked to health behaviors appeared consistent regardless of the presence of psychosocial stress.
