Archaeologists at UC Santa Cruz used predictive modeling to map strontium isotope ratios across all of modern-day Angola, a region in Southwest Africa that was once a major hub for the transatlantic ...

Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are ...

Tracing the regional origin of everything from milk to invasive bugs is now possible thanks to a new project. A strontium isotope map means biological material can be pinpointed to distinct ...

Tokyo, Japan –Did you know that we can track the journey of a drop of water through space and time? Water is made of hydrogen and oxygen, and ...

Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called ...

The continental volcanism, oceanic volcanism and mid-ocean ridge volcanism emit Hg to the atmosphere and ocean. Mercury in atmosphere deposit to aquatic and terrestrial systems via wet or dry ...

LI-COR Inc., a global leader in environmental measurement technology, announced its forthcoming LI-7825 CO 2 Isotope Trace Gas Analyzer, which will measure CO 2 isotopes in the lab, in the field, and ...

As cities worldwide face growing water stress, an IAEA-coordinated research project demonstrates that isotopic techniques offer a powerful way to safeguard this vital resource. A five-year IAEA ...

Scientists have found a clever way to trace water as it moves through the atmosphere, using something most of us probably don’t think about: the atoms. These “fingerprints” left behind by water ...

Shark teeth have long fascinated humans. From your average beach-comber stumbling across one embedded in the sand, to a paleontologist trying to determine their ...
