NASA/WikiCommons Until recently it was thought neutron star mergers were the only way heavy elements (heavier than Zinc) could be produced. These mergers involve the mashup of the remnants of two massive stars in a binary system. But we know heavy elements were first produced not long after the Big Bang, when […]

The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance as an organizing principle in chemistry – all budding chemists become familiar with it from the earliest stages of their education. […]

Asteroid strikes upset the environment and provide clues via the elements they leave behind. Now, University of Tsukuba researchers have linked elements that are enriched in the Cretaceous–Paleogene (KPg) boundary clays from Stevns Klint, Denmark, to the impact of the asteroid that produced the Chicxulub crater at the Yucatán Peninsula, […]
