Nitrogen interventions as a key to better health and robust ecosystems      (via sciencedaily.com)     Original source 

An international research team combined multidisciplinary methods to evaluate how nitrogen interventions could improve air quality and reduce nitrogen deposition. Their study found that interventions, such as improving fuel combustion conditions, increasing agricultural nitrogen use efficiency, and reducing food loss and waste, could significantly lower premature deaths attributed to air pollution, crop losses, and ecosystems risks.

Scottish and Irish rocks confirmed as rare record of 'snowball Earth'      (via sciencedaily.com)     Original source 

The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.

It's a rave: Underground acoustics amplify soil health      (via sciencedaily.com)     Original source 

Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.
