This compilation features five liquid nitrogen experiments that show what extreme cold really does to everyday materials. Watch objects freeze almost instantly, turn brittle, and break in ways that ...

Unrealistic scientific experiments mean the true impact of nitrogen pollution on the environment remains poorly understood, a new study warns. Human actions – mostly burning of biomass and fossil ...

Flaws in the design of experiments studying the effects of nitrogen pollution have obscured its true impact, according to research published Wednesday by the University of Exeter. In the study, ...

To validate these findings, the researchers conducted field experiments in a rice growing region in eastern China. The results confirmed the pattern observed in the meta-analysis. Under high nitrogen ...
