At first, Professor Glen Jackson, who teaches forensic and investigative science at West Virginia University, had a hard time explaining to me what isotopes are. He told me he is used to speaking with ...

The detection and study of isotopes, atoms of the same element that have different numbers of neutrons, could expand the ...

Researchers in China have developed an atom-counting method that detected atmospheric argon-42 at a concentration of just one part in 10²¹, setting a new benchmark for isotope rarity. The achievement, ...

The compositional analysis of wine, which encompasses multi-element profiling and stable isotope investigations, has rapidly evolved into a vital instrument for establishing provenance, confirming ...

Isotope analysis, and in particular compound‐specific stable isotope analysis (CSIA), has emerged as an indispensable tool in the investigation of environmental biodegradation. By measuring the subtle ...

Isotopic analysis primarily involves the separation of isotopes based on the significant differences in mass. The method is effective for identifying the isotopic signature within the inorganic and ...

Carbon isotope analysis is an analytical method that quantifies the relative abundance of stable carbon isotopes, primarily ¹²C and ¹³C, in a sample to infer biogeochemical processes, sources, and ...

Demand for the ornaments, jewelry, and other luxury items carved from the ivory in elephant tusks has led poachers to decimate elephant populations. An international ban exists on the ivory trade, and ...

Tagging animals is among the oldest and most valuable techniques in wildlife management. Before its use, many questions could only be met with guesses. Where does a species migrate? What is the size ...

Dec. 1 (UPI) --A new isotope analysis of 77 paintings created by 27 Dutch artists has revealed subtle differences in a common white pigment that are directly tied to supply routes altered by ...
