Adverse childhood experiences (ACE) significantly impact physical, mental and social well-being, making them a critical area of research. This study analyzed the emerging trends and intellectual structure of ACE research and identified key contributors, including the most productive nations, journals and authors. Using bibliometric tools and VOSviewer software (version 1.6.20), 1,957 articles from the Scopus database (2004 to March 2024) were systematically analyzed. A notable finding was the surge in ACE-related publications during the COVID-19 pandemic, potentially reflecting increased global attention on childhood adversity amid heightened social and economic challenges. The analysis also revealed a striking dearth of studies from the Global South, with the field predominantly shaped by Western nations, like the United States, the United Kingdom, Australia and Canada. Leading journals, such as the Journal of Interpersonal Violence, and prolific authors, like Kevin T. Wolff, played a central role in advancing the field. Co-citation analysis uncovered four thematic clusters: (1) conceptualization and assessment of ACE, (2) health implications, (3) mental health impacts and (4) juvenile delinquency. These clusters, though distinct, showed significant thematic overlaps, reflecting the interconnected nature of ACE research and its intellectual structure. These findings underscore the need for more regionally diverse and interdisciplinary approaches to understanding global childhood adversity.

We investigate the distribution of archaeal lipids in a 5.8-m-long sedimentary core recovered from Lake Qinghai to extract regional hydroclimate and temperature signals since the last deglaciation for this important region. The paleohydrology was reconstructed from the relative abundance of thaumarchaeol (%thaum) and the archaeol and caldarchaeol ecometric (ACE) index. The %thaum-inferred lake-level record was extended to deglaciation, showing three periods (11.9–13.0, 14.1–14.7 and 15.1–17.2 cal ka BP) with relatively higher lake levels than those during the early Holocene. The ACE record demonstrates three periods (10.6–11.2, 13.2–13.4 and 17.4–17.6 cal ka BP) of elevated salinity when the lake was shallow. Filtered TEX86 record based on archaeal lipid distributions corresponded to relatively higher lake levels, implying that a certain lake size is required for using the TEX86 paleothermometer. At 1–4 cal ka BP, the reconstructed temperature fluctuated significantly and correlated negatively with inferred lake level, indicating that lake temperature and hydrological change might be coupled during this period. We attribute this co-variance to the importance of summer temperature in controlling evaporation for this arid/semi-arid region. Moreover, our results indicate that archaeal lipids have potential in reconstructing paleoclimate patterns from lacustrine sedimentary cores, but the data should be interpreted with care.

We demonstrate how a particular type of knowledge about objects, their spatial locations and thus how to direct actions toward them, contributes to the comprehension of language about those objects. In four experiments, participants judged if sentences were about normal objects (e.g., “The apple has a stem”) or odd objects (e.g., “The apple has an antenna”). The Normal response key was either on the left of a response box or on the right. The named objects were themselves either on the left or the right of the response box. We demonstrate a compatibility effect in which responding Normal to the side where the object was located was faster than responding Normal to the opposite side. Furthermore, this effect was equally strong for sentences describing states of the objects (as above) and sentences describing actions (e.g., “Touch the apple at the stem”); the compatibility effect was found when the objects were removed; the effect required compatibility between actions, not just spatial locations; and the effect was found in both English and German. The results are discussed in relation to how action systems are used in language comprehension.

Attitudes towards foreign policy have typically been explained by ideological and demographic factors. We approach this study from a different perspective and ex amine the extent to which foreign policy preferences correspond to genetic variation. Using data from the Minnesota Twin Family Study, we show that a moderate share of individual differences in the degree to which one's foreign policy preferences are hawkish or dovish can be attributed to genetic variation. We also show, based on a bivariate twin model, that foreign policy preferences share a common genetic source of variation with political ideology. This result presents the possibility that ideology may be the causal pathway through which genes affect foreign policy preferences.

The aim of this study was to investigate the effects of enzymatic hydrolysis with digestive enzymes of camel whole casein and beta-casein (β-CN) on their antioxidant and Angiotensin Converting Enzyme (ACE)-inhibitory properties. Peptides in each hydrolysate were fractionated with ultra-filtration membranes. The antioxidant activity was determined using a Trolox equivalent antioxidant capacity (TEAC) scale. After enzymatic hydrolysis, both antioxidant and ACE-inhibitory activities of camel whole casein and camel β-CN were enhanced. Camel whole casein and β-CN showed significant ACE-inhibitory activities after hydrolysis with pepsin alone and after pepsinolysis followed by trypsinolysis and chymotrypsinolysis. Camel β-CN showed high antioxidant activity after hydrolysis with chymotrypsin. The results of this study suggest that when camel milk is consumed and digested, the produced peptides start to act as natural antioxidants and ACE-inhibitors.

Genes undoubtedly play a role in the development of a successful athlete. This view has flourished on anecdotes such as the observation of a child who displays the same aptitude for a particular sport as one of their parents, or a pair of sisters who both excel in the same discipline. However, the conclusions made from this type of observation have an obvious limitation: that similar environmental factors may be just as responsible as genetic inheritance in explaining the passage and sharing of talent between family members. Here, we review briefly the salient data showing that genes do play a role in athletic performance, and although the data examining the effect of specific genes are limited, we present data examining the role of the angiotensin-converting enzyme gene in human physical performance.
