We introduce a novel high-precision method for oxygen-isotope analysis of iron (oxyhydr)oxides using high-temperature conversion isotope ratio mass spectrometry (HTC-IRMS). In this approach, a finely ...

High over the frozen surface of Greenland, a new tool is rewriting what scientists know about how water moves through the ...

For the first time, scientists have captured detailed measurements of water vapor high above Greenland’s vast ice sheet.

Lithium-6 is a crucial material for nuclear fusion reactors, but isolating it is challenging – now researchers have found a ...

Besides the water seen flowing in lakes and rivers or frozen in glaciers and ice caps, most freshwater goes unseen in underground aquifers. Isotope hydrology, a form of nuclear science, comes into the ...

Promethium’s short half-life and lack of stable isotopes makes it difficult to study. In addition, promethium is difficult to ...

Our ancient ancestors have done some interesting things to human bones over the years, but one example from the Iron Age Iberian Peninsula is a real puzzle.

For example, hydrogen has 1 proton and an atomic number of 1, while oxygen has 8 protons and an atomic number of 8. On the other hand, the number of neutrons can vary. The most common isotope ...

Oxygen therapy for COPD is a treatment used to increase the oxygen in your lungs and bloodstream. Research suggests that people with chronic obstructive pulmonary disease (COPD) who use oxygen may ...

Theia and Earth did not combine to form Moon, a new study suggests. The Moon might be a part of only Earth, a sibling 384,400 ...
