Current Agriculture Adds More Phosphorus to Streams Than to Lakes

Rachel Fritts, Science Writer by Rachel Fritts 17 August 202317 August 2023

Improved agricultural nutrient management could improve stream water quality by reducing phosphorus levels, but rising temperatures and rainfall due to climate change might offset improvements.

Scientists Discover a Way of Forming Suspended Layers of Sediment

Katherine Kornei, Science Writer by Katherine Kornei 1 August 20232 August 2023

Laboratory experiments suggest that underwater gas eruptions—due to the venting of gas hydrates, for example—could trigger the formation of layers of suspended sediment in the ocean.

Ambidextrous Microbes May Pump Out CO2 as Temperatures Rise

Katherine Kornei, Science Writer by Katherine Kornei 7 July 20237 July 2023

Certain microbes that engage in both photosynthesis and predation are more likely to do the latter as the planet warms, resulting in a net release of carbon dioxide.
