Climate modeling suggests that if the Earth warms by 3 °C by the late 21st century, hurricane-induced power outages will increase significantly in northern Florida, Georgia, the mid-Atlantic, and the North Atlantic coast. In PNAS: ow.ly/Lu7I50Xgj05
Projected changes in the annual proportion of the population experiencing power outages per census tract, calculated as the difference in power outage rates between the hindcast period (1995–2014) and the late century period (2071–2100) considering a 3 °C of warming scenario.

Episodic carbonate cementation in a Miocene Eger Rift paleolake was driven by a combination of climatic, hydrological, and biogeochemical factors, including increased humidity, weathering, and variable solute fluxes.

The buildings of the future might also be giant batteries. Improved electron-conducting carbon concrete can bear weight and store energy. A key to performance is the nanoscale connectivity of the electrode’s conductive carbon network. In PNAS: ow.ly/7rZa50XaBiC
Using focused ion beam (FIB) milling and scanning electron microscopy, it is possible to reconstruct the complex internal nano-architecture of electron-conducting carbon-cement. Illustrated here is a magnified view of a single FIB slice highlighting the pores.

Earth Was a Fungal World Before Plants Existed
Fungi arose long before plants, shaping Earth with early soils and nutrient cycles. Their hidden legacy shows they may have prepared the world for life to flourish on land.
