Adaptation actions such as assembling an emergency kit lowers people’s perceptions of risk from hurricanes in Florida and Texas, despite the growing intensity of storms as the climate warms, paradoxically leaving people less prepared. In PNAS Nexus: ow.ly/T0Lz50RcJaC

Watching the solar eclipse today? Dive into this classic research article from the inaugural volume of PNAS about solar eclipses titled, “Results of an Investigation of the Flash Spectrum Without an Eclipse.” Read now: ow.ly/VWV150Ratg4

A study explores how the Mackenzie River in the Canadian Arctic transports old carbon—up to 2,380 years old—from thawing permafrost. As water flows from tributaries to the delta, some of the old carbon degasses into the atmosphere. In PNAS Nexus: ow.ly/zfpB50R9UjP

Watch a simulation of a bacterial weapon called a bacteriocin as it squeezes through a cell surface receptor to enter the bacteria P. aeruginosa. Similar mechanics could be used to introduce antibiotics into drug-resistant bacterial pathogens. ow.ly/Jqmi50R9Uji

Pedestrian crowds can flow like a fluid. A study proposes a dimensionless number, similar to those used in fluid mechanics, to characterize how people move without colliding or intruding on one another’s personal space. In PNAS Nexus: ow.ly/T7UH50R4qlb

An artificial reef made of modular concrete voxels can dissipate wave energy better than a natural coral reef—and could provide habitat for marine life. In PNAS Nexus: ow.ly/Sxkh50R4cav

By using trained models, researchers successfully placed nine fossil Podocarpidites specimens within a phylogeny.
