In a pioneering study that explores innovative solutions for soil salinization, researchers are investigating the effects of subsurface organic fertilization on microbial necromass accumulation in saline soils. The study, titled "Subsurface Application of Organic Ameliorant in Saline Soils Increases Microbial Necromass Accumulation in Mineral-Associated Organic Matter," is led by Prof. Yuyi Li from the State Key Laboratory of Efficient Utilization of Arable Land in China at the Chinese Academy of Agricultural Sciences in Beijing, China. This research offers valuable insights into how subsurface organic fertilization can enhance soil health and mitigate the impacts of salinization.

Tiny ocean organisms living in oxygen-poor waters turn nutrients into nitrous oxide—a greenhouse gas far more powerful than carbon dioxide—via complex chemical pathways.

Penn’s Xin Sun and collaborators identified the how and why behind these chemical reactions, showing that microbial competition, not just chemistry, determines how much N₂O is produced.

Their findings pave the way for more reliable climate models, making global greenhouse gas estimates more effective, predictable, and easier to understand in response to natural and man-made climate change.

A University of Sydney student has developed a completely new way to peer inside coral fossils to recover lost records of past climate change. The method opens the door to recovering climate information from coral samples once written off as too altered to be useful
