Bacteria drive many of the processes that regulate soil fertility, carbon cycling, and groundwater quality, yet how they locate nutrients in complex subsurface environments remains poorly understood. Researchers from ETH Zurich and Eawag show that the physical heterogeneity of porous soils enhances bacterial chemotaxis, helping microorganisms reach nutrient hotspots even under fluid flow. The findings open new perspectives for predicting and managing subsurface ecosystem processes.

Using Earth Observation to Support Mining Monitoring in Namibia

After an exceptionally early heatwave in May, western Europe recorded its hottest June on record. Immediate protection is essential, but not everyone can access cool housing, shade or flexible working conditions. A new Thermal Justice framework shows how cities can reduce heat risk without shifting its burdens to other people, places or future generations.
