Inequality between the sexes is pervasive both outside and inside the home. One contributing factor could be the dispersal of one sex at marriage that sets up sex-specific differences in relatedness to the group. Here we exploit the ecological diversity and different social structures found in southwest China to investigate the role of sex-biased dispersal on inequality in the sexual division of labor. We use a wearable fitness tracker and validated readings by confirming that participants' daily "steps" were positively correlated with time spent in high-energy activities, such as agriculture and animal husbandry work, and negatively correlated with low-energy activities, such as leisure and relaxation. We applied multilevel comparative approaches to examine the relative workload pattern between the sexes under different dispersal states. Our results reveal two characteristics that lead to an unfavorable division of workload: being female and dispersing at marriage. This is consistent with the hypothesis that males have increased bargaining power when remaining in their natal home, leading to inequality in workload.

The burden of COVID-19 was heterogeneous, indicating that the effects of this disease are synergistic with both other non-communicable diseases and socioeconomic status (SES), highlighting its syndemic character. While the appearance of vaccines moderated the pandemic effects, their coverage was heterogeneous too, both when comparing different countries, and when comparing different populations within countries. Of note, once again SES appears to be a correlated factor.

The exposure to extreme heat at workplaces poses substantial threat to human effort and manual labour. This becomes more prominent due to the global dispersion of labour-intensive production activities via trade. We combine a climate model with an input-output model to quantify the risks associated with trade-related occupational extreme heat exposure.

- Photon-based entanglement sources, essential for creating entangled states, often suffer from quality loss due to birefringence in nonlinear crystals during spontaneous parametric down-conversion.
- The study provides a theoretical analysis of birefringent walk-off and demonstrates that using pre- and post-compensation can improve entangled photon quality.
- Experimental validation shows significant success, achieving a violation of CHSH-Bell's inequality by about 366 standard deviations, making this method applicable to various optical quantum technologies, such as computation, sensing, and communication.
Methods for Quantifying Source-Specific Air Pollution Exposure to Serve Epidemiology, Risk Assessment, and Environmental Justice.

Identifying sources of air pollution exposure is crucial for addressing their health impacts and associated inequities. Researchers have developed modeling approaches to resolve source-specific exposure for application in exposure assessments, epidemiology, risk assessments, and environmental justice. We explore six source-specific air pollution exposure assessment approaches: Photochemical Grid Models (PGMs), Data-Driven Statistical Models, Dispersion Models, Reduced Complexity chemical transport Models (RCMs), Receptor Models, and Proximity Exposure Estimation Models.

Article Synopsis
- The IRDiRC Telehealth Task Force investigated how telehealth can enhance diagnosis, care, research, and education related to rare diseases by reviewing literature from 2017 to 2023 and identifying effective models and strategies.
- The COVID-19 pandemic significantly boosted the adoption of telehealth, highlighting its ability to overcome geographical barriers and improve access to specialized care for rare disease patients.
- While telehealth presents several benefits, such as decentralized clinical research and enhanced education for local healthcare providers, it also has limitations, including challenges in performing physical exams and building personal relationships with healthcare professionals, thus suggesting it should complement traditional care rather than replace it.
