UL's campus oaks have stood tall for over 100 years, but they are still revealing new information about our environment.

We measure carbon and oxygen isotopes in air and ice to better understand Earth systems, including the carbon cycle, past climate, and methane. In August, Jianghanyang (Ben) Li joined Department of ...

Marissa Grunes is a freelance science writer and Lecturer in the Herbst Program for Engineering, Ethics and Society at CU Boulder. Every semester, she takes first-year Engineering students on a tour ...

Stable isotope analysis, chiefly of carbon (δ13C) and nitrogen (δ15N), has revolutionised our understanding of marine mammal ecology by providing indirect yet integrative measures of diet, trophic ...

Examples of stable isotopes being used to support research include, studying water extraction methods from plants, to how habitat changes have incited more attacks by coyotes on humans. Stable ...

For the first time, researchers, including those from the University of Tokyo, have found out how to determine how much ...

The IAEA offers a variety of training courses in the fundamentals of isotope hydrology and isotopic analyses of stable isotopes, tritium, and noble gases. This course provides an overview of advances ...

Precipitation stable isotopes can be used to trace the water cycle and to interpret paleoclimate archives. Forecasts of natural and future anthropogenic impacts on climate affecting fresh water ...

A mosasaur tooth found alongside a T. rex tooth and a crocodilian jaw in North Dakota has led researchers to argue that some ...

The discovery of stable ''isotopes" began with J. J. Thomson's identification of neon-22 in 1912 (Bievre et al., 1984). More than 90 naturally occurring elements have been identified on the earth; ...
