Multiple tipping points in the Earth system could be triggered when global warming exceeds specific thresholds. However, the degree of their impact on the East Asian hydroclimate remains uncertain due to the lack of quantitative rainfall records. Here we present an ensemble reconstruction of East Asian summer monsoon (EASM) rainfall since the Last Glacial Maximum (LGM) using nine statistical and machine learning methods based on multi-proxy records from a maar lake in southern China.

Solid organ transplant recipients (SOTRs) have a heightened risk of adverse coronavirus disease 2019 (COVID-19) outcomes because of immunosuppression and medical comorbidity. We quantified the burden of COVID-19 mortality in United States (US) SOTRs. A sample of deaths documented in the US solid organ transplant registry from June 2020 through December 2022 was linked to the National Death Index to identify COVID-19 deaths and weighted to represent all SOTR deaths during the study period.

The terrestrial subsurface harbors unique microbial communities that play important biogeochemical roles and allow for studying a yet unknown fraction of the Earth's biodiversity. The Saint-Leonard cave in Montreal City (Canada) is of glaciotectonic origin. Its speleogenesis traces back to the withdrawal of the Laurentide Ice Sheet 13,000 years ago, during which the moving glacier dislocated the sedimentary rock layers.

Purpose: The long-term development of talent in endurance sports is a topic of interest. Among various factors, the importance of total hemoglobin mass (tHbmass) and the potential benefits of being an altitude-native athlete remain unclear, particularly in young categories. This study aimed to investigate the impact of altitude and training content on hematological characteristics by comparing young male cyclists age 15-16 and 17-18 years who were born and trained at a moderate altitude (ie, greater than or equal to 2500 m; MA) and cyclists who were born and trained at low altitude (below 1000 m; LA).

Although olfaction is well known to guide animal behavior, the neural circuits underlying the motor responses elicited by olfactory inputs are poorly understood. In the sea lamprey, anatomical evidence shows that olfactory inputs project to the posterior tuberculum (PT), a structure containing dopaminergic (DA) neurons homologous to the mammalian ventral tegmental area and the substantia nigra pars compacta. Olfactory inputs travel directly from the medial olfactory bulb (medOB) or indirectly through the main olfactory bulb and the lateral pallium (LPal).

Challenging behaviors (CB) are a frequent co-occurring problem in children with autism spectrum disorder (ASD) and hinder their response to recommended interventions such as early intensive behavioral intervention (EIBI). The Prevent-Teach-Reinforce for young children (PTR-YC) program was implemented to meet community-based EIBI educators' training and support needs in managing CB in their day-to-day work with families. Although this positive behavior support program has a strong empirical basis, its implementation by community-based educators has yet to be assessed from a systematic and structured program evaluation perspective.

Cumulative childhood trauma (CCT) increases the risk of experiencing interpersonal problems and relationship distress in adulthood. However, not all CCT survivors experience such difficulties, and little research has investigated protective factors against relationship dissatisfaction in CCT survivors and their partners. Romantic attachment might be one such factor that could reduce the harmful effects of a CCT history on relationship satisfaction for both survivors and their partners.

Article Synopsis
  • - The study investigated sleep habits of Quebec resident physicians and found that many experience social jetlag, which is the misalignment between required and actual sleep schedules, impacting their health.
  • - An online questionnaire collected data on various factors including sleep duration and disturbances; results showed an average sleep debt of 1.59 hours and significant sleep issues affecting over half the participants.
  • - The findings suggest that severe social jetlag correlates with factors like less physical activity and depressive symptoms, highlighting the need for interventions to support the mental health of resident physicians.

The field of metabolomics has gained tremendous interest in recent years. Whether the goal is to discover biomarkers related to certain pathologies or to better understand the impact of a drug or contaminant, numerous studies have demonstrated how crucial it is to understand variations in metabolism. Detailed knowledge of metabolic variabilities can lead to more effective treatments, as well as faster or less invasive diagnostics.

Microplastics in the aquatic environment are susceptible to colonization by surrounding microorganisms, which form biofilms over the microplastic's surface. These biofilm-laden microplastics can then interact with a diverse array of contaminants. In the present study, biofilms were grown on microplastics in a laboratory setting using Pseudomonas aeruginosa as a model biofilm-forming bacterium for periods of 5 to 15 days.
