Tomography helps detect microplastics in soil

,
A German research team has developed a new method for detecting microplastics. The technique employs neutron beams and X-rays to generate a complete image

The phosphorus problem started thousands of years ago

,
A Swiss study found that humans began altering the phosphorus cycle many millennia ago. Before industrialization and the spread of fertilizers accelerated the process

Soil microbe analysis can replace drilling in the mining sector

,
A Canadian study shows how microbes can be reliable indicators of the presence of diamonds underground. Analyzing their DNA can prevent high-impact exploration
