Measuring competing outcomes of a single-molecule reaction reveals classical Arrhenius chemical kinetics.

Programming matter one molecule at a time is a long-standing goal in nanoscience. The atomic resolution of a scanning tunnelling microscope (STM) can give control over the probability of inducing single-outcome single-molecule reactions. Here we show it is possible to measure and influence the outcome of a single-molecule reaction with multiple competing outcomes.

New Linked Employee-Employer Data Show Workforce Composition Is Associated With Health Insurance Offers Among Small Employers.

Decades of research shows that small firms are much less likely to offer health insurance than large firms, but less is known about differences among small employers. We examine this issue using the Medical Expenditure Panel Survey-Insurance Component with Administrative Records (MEPS-ICAR), a unique employer-employee linked data set that is constructed by matching the Medical Expenditure Panel Survey-Insurance Component (MEPS-IC) to Internal Revenue Service administrative records and the Decennial Census. Multivariate analyses show that among firms with fewer than 50 workers, the probability that workers receive an insurance offer is positively associated with higher median workforce incomes, and conditional offers of dependent coverage increase when the majority of workers are married or from a family with at least three members.

Co-located ecological data for exploring top- and subsoil carbon dynamics across grassland-woodland contrasts.

Soil organic carbon (SOC) is a soil health indicator and understanding dynamics changing SOC stocks will help achieving net zero goals. Here we present four datasets featuring 11,750 data points covering co-located aboveground and below-ground metrics for exploring ecosystem SOC dynamics. Five sites across England with an established land use contrast, grassland and woodland next to each other, were rigorously sampled for aboveground (n = 109), surface (n = 33 soil water release curves), topsoil, and subsoil metrics.
