In two separate studies, researchers identify nucleosynthetic isotope anomalies in the volatile elements potassium (K) and zinc (Zn) in meteorites, which constrain the origins of the material that ...

For many years, scientists have predicted that many of the elements that are crucial ingredients for life, like sulfur and nitrogen, first came to Earth when asteroid-type objects carrying them ...

For years, scientists have puzzled over why Earth and Mars are missing certain key elements. Now, a fresh study suggests these ingredients weren’t missing from the start. Instead, they were likely ...

In 1992, an episode of The Simpsons posed an important question to primetime television audiences: what would happen if you lived in a world without zinc? The sequence, a spoof of the 1940 Chevrolet ...

Earliest inner solar system planetesimals shaped the inventory of moderately volatile elements in terrestrial planets. Understanding where Earth's essential elements came from -- and why some are ...

Earth's rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet's molten youth using advanced quantum mechanical simulations, revealing ...

Decades-old radioactive glass found blanketing the ground after the first nuclear test bomb explosion is being used by scientists to examine theories about the Moon's formation some 4.5 billion years ...
