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.

Researchers unveil mysteries of ancient Earth      (via sciencedaily.com)     Original source 

A team of researchers has made strides in understanding the formation of massif-type anorthosites, enigmatic rocks that only formed during the middle part of Earth's history. These plagioclase-rich igneous rock formations, which can cover areas as large as 42,000 square kilometers and host titanium ore deposits, have puzzled scientists for decades due to conflicting theories about their origins.

Newly discovered ability of comammox bacteria could help reduce nitrous oxide emissions in agriculture      (via sciencedaily.com)     Original source 

An international research team has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source. This unique ability opens new avenues for targeted cultivation of these enigmatic microbes and could also provide a key to reducing agricultural nitrous oxide emissions.

Scientists achieve more than 98% efficiency removing nanoplastics from water      (via sciencedaily.com)     Original source 

Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.

Delivery robots' green credentials make them more attractive to consumers      (via sciencedaily.com)     Original source 

The smaller carbon footprint, or wheel print, of automatic delivery robots can encourage consumers to use them when ordering food, according to a new study. The suitcase-sized, self-driving electric vehicles are much greener than many traditional food delivery methods because they have low, or even zero, carbon emissions. In this study, participants who had more environmental awareness and knowledge about carbon emissions were more likely to choose the robots as a delivery method. The green influence went away though when people perceived the robots as a high-risk choice -- meaning they worried that their food would be late, cold or otherwise spoiled before it arrived.
