| Open AccessInequality in economic shock exposures across the global firm-level supply network
Thurner and colleagues explore how economic shocks spread risk through the globalized economy. They find that rich countries expose poor countries stronger to systemic risk than vice-versa. The risk is highly concentrated, however higher risk levels are not compensated with a risk premium in GDP levels, nor higher GDP growth. The findings put the often-praised benefits for developing countries from globalized production in a new light, by relating them to risks involved in the production processes

| Open AccessNoncovalent interaction with a spirobipyridine ligand enables efficient iridium-catalyzed C–H activation
Exploitation of noncovalent interactions has received much attention for the design of metal catalysts. However, because of the weak nature, CH-π interactions have been less utilized for the control of organic reactions. Here, the authors report that the CH-π interaction can be used to kinetically accelerate catalytic C-H activation of arenes.
