National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas
Sustainable Development, EarlyView.ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Improving Human Diving Endurance With a Field‐Deployable Exoskeleton
SmartBot, EarlyView.High energetic demands to overcome drag, combined with a finite supply of self‐contained breathing gas, fundamentally limit human endurance in underwater locomotion. Here, we present DiveMate, a portable exoskeleton that provides adaptive bidirectional assistance synchronized with fin‐kicking during diving, reducing lower‐limb muscle activation and ...
