Breaking boundaries in water research

A virus that infects harmful freshwater cyanobacteria is challenging one of biology’s most fundamental assumptions about the difference between viruses and living cells.

Published in The ISME Journal, new research reveals that the jumbo cyanophage PhiMa05 carries the largest set of ribosomal protein genes ever found in a virus. The discovery is prompting scientists to rethink how viruses evolve and where the line between viral and cellular life truly lies.

This article brings together the work of two graduate students studying water scarcity in Bauru, Brazil, from complementary perspectives. One examines the fragile groundwater systems beneath the city and the risks created by aging infrastructure. The other investigates how households cope when the formal water supply becomes unreliable. Together, their research reveals how hidden water systems, both underground and within homes, are sustaining the city, while also creating new risks and inequities.

New research from University of Waterloo and Penn State researchers suggests that fertilizer shortages linked to global conflict may be having an unexpected effect on water quality.

The researchers found that in nutrient-rich agricultural systems, farmers may be able to tap into legacy nutrient reserves already stored in the soil, reducing the need for additional fertilizer and decreasing nutrient runoff into rivers, lakes and streams.
