Extremism does not stop at borders, and neither should our models

The Democracy Index finding holds up best. Its negative direct effect on offensive VEI (we use β for SDM coefficients throughout) survives spatial adjustment in every bivariate specification (Table 1) ...

Wind turbine proximity and health: Longitudinal evidence from US households

Wind energy expansion is crucial for decarbonization but faces community resistance due to health concerns about turbine noise and infrasound. We combine US wind turbine data (2011–2023) with ...

Terrestrial ecosystem nitrogen cycling in response to field warming: Global patterns and future trends

Nitrogen cycling regulates ecosystem productivity and carbon storage, yet its global responses, mechanisms, and future trajectories under climate warming remain poorly understood. By integrating 7,941 ...

Human amplification of climate-induced greenhouse gas emissions from global small water bodies

Small water bodies (SWBs) are critical but often overlooked components of the global carbon cycle. We demonstrate that human activities, particularly agricultural nutrient loading and urbanization, ...

DEPENDENCE OF THE KINETICS OF SINGLET-SINGLET ENERGY TRANSFER ON SPECTRAL OVERLAP

Electronic excitation energy can be transferred between chromophores separated by distances of the order of 30 Å. Förster proposed that the transfer occurs by a dipole-dipole resonance interaction ...

A transparent universal credit system to incentivize peer review

It’s increasingly hard to find peer reviewers. To address the problem, we propose a universal peer-review system based on the exchange of credits. Image credit: Dave Cutler (artist). Several factors ...

Intramolecular bonding as a design strategy for robust intermolecular binding of oligomers

Molecular recognition processes are ubiquitous to enact function. The current materials design efforts focused on energetics as primary factor to tune binding are suboptimal because they overlook the ...
