Large Differences in Herbivore Performance Emerge From Simple Herbivore Behaviours and Fine-Scale Spatial Heterogeneity in Phytochemistry.

Patterns of phytochemistry localisation in plant tissues are diverse within and across leaves. These spatial heterogeneities are important to the fitness of herbivores, but their effects on herbivore foraging and dietary experience remain elusive. We manipulated the spatial variance and clusteredness of a plant toxin in a synthetic diet landscape on which individual caterpillars fed.

Allostatic Load, Educational Attainment, and Risk of Cancer Mortality Among US Men.

Importance: Health disparities among racial and ethnic minoritized populations, particularly for cancer mortality rates, remain a major public health concern. Men from underrepresented backgrounds (Black and Hispanic men, specifically) face the pervasive effects of discrimination in their daily lives, which also contribute to the complex associations among allostatic load (a marker of chronic stress), educational opportunities, and elevated risks of cancer mortality.

Objective: To elucidate the associations among educational attainment, allostatic load, and cancer mortality risk among men.

Resilient plants, sustainable future.

The accelerated pace of climate change over the past several years should serve as a wake-up call for all scientists, farmers, and decision makers, as it severely threatens our food supply and could result in famine, migration, war, and an overall destabilization of our society. Rapid and significant changes are therefore needed in the way we conduct research on plant resilience, develop new crop varieties, and cultivate those crops in our agricultural systems. Here, we describe the main bottlenecks for these processes and outline a set of key recommendations on how to accelerate research in this critical area for our society.

Disparities in Genetic Testing for Inborn Errors of Immunity.

Background: Inequities in genetic testing have been documented in a range of diseases, and no-charge genetic testing programs have been proposed as a means to enhance access. However, no studies have examined disparities in genetic testing for inborn errors of immunity (IEI) and the impact of no-charge programs on testing equity.

Objective: To examine socioeconomic, geographic, and racial disparities in the uptake of genetic testing for IEI in the United States and the impact of a no-charge sponsored program on testing equity.
