Acid-base accounting is a predictive geochemical method used to quantify the net acid-generating or acid-neutralizing potential of geological or waste materials, particularly in the context of acid mine drainage or acid sulfate soils. It typically involves determining total sulfur or sulfide sulfur concentrations as a proxy for potential acidity, and measuring carbonate or other neutralizing mineral contents to estimate neutralization potential. These parameters are combined, often as net acid producing potential (NAPP) and net neutralization potential (NNP), to classify materials as potentially acid-forming, non-acid-forming, or uncertain, thereby informing management, remediation, and regulatory decisions.
At least one of Colorado's collared wolves roamed widely across southwestern Colorado in the last month, a new map of wolf locations released by Colorado Parks and Wildlife shows. One of the state's 19 collared wolves traveled ...

Many people have probably seen birds picking up small pieces of man-made materials, like strips of a plastic bag or paper litter, and taking them into their nest. This behavior appears to be fairly widespread among birds. ...
A new study from North Carolina State University identifies vertebrate hemoglobin in bone extracts from two dinosaurs and shows that this molecule is original to those animals. The work also shows how heme, a small molecule ...
