A number of features of zircon (ZrSiO4), including high U-Th concentrations, high
abundance in a wide range of lithologies, refractory nature under metamorphic and some …

Zircon and rutile are common accessory minerals whose essential structural constituents, Zr,
Ti, and Si can replace one another to a limited extent. Here we present the combined results …

Ancient zircons from Western Australia's Jack Hills preserve a record of conditions that
prevailed on Earth not long after its formation. Widely considered to have been a uniquely …

The electromagnetic transients accompanying compact binary mergers (γ-ray bursts,
afterglows and 'macronovae') are crucial to pinpoint the sky location of gravitational wave …

Neutron star mergers have been long considered as promising sites of heavy r-process
nucleosynthesis. We overview the observational evidence supporting this scenario …

There are substantial barriers to the introduction of hydrogen fuel cells for transportation,
including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and …

A fundamental outcome of modern nuclear microscopic theory is the prediction of the'islands
of stability'in the region of hypothetical superheavy elements (SHEs). In a heavy nucleus …

Half of the heavy elements including all actinides are produced in r-process
nucleosynthesis, whose sites and history remain a mystery. If continuously produced, the …

The first∼ 600 million years of Earth history (the 'Hadean'eon) remain poorly understood,
largely because there is no rock record dating from that era. Detrital Hadean igneous zircons …

The origins and near-surface distributions of the~ 250 known uranium and/or thorium
minerals elucidate principles of mineral evolution. This history can be divided into four …
