Geomagnetic Storms Probably Don’t Cause Mass Cetacean Strandings
Solar-induced geomagnetic activity and mass strandings of whales and dolphins on shorelines both show seasonal patterns, but the beachings likely result from multiple environmental factors.

The Lasting Legacy of Phosphorus Buried in Lakes
Research at an experimental lake suggests that phosphorus inputs from runoff may affect the health of aquatic ecosystems long after external additions of the nutrient are reduced.

Soil Remains Warmer and Drier After Long-term Warming Stops
Pausing a long-term soil warming experiment revealed that previously warmed plots remained both warmer and drier compared to plots which had not experienced previous soil warming.

Estuary Research Suffers from Scientific Bias
Researchers are calling for a closer look at nutrient cycling in tropical and low-nutrient estuaries, which have long been overlooked in the scientific literature.
