Molybdenum is an essential trace element for human, animal and plant health and has
played an important part in the evolution of life on earth. Nonetheless, exposure to the …

“The Answer to the Great Question... Of Life, the Universe and Everything... Is... Forty-two,”

The origin of oxygenic photosynthesis was the most important metabolic innovation in Earth
history. It allowed life to generate energy and reducing power directly from sunlight and …

To improve estimates of the extent of ocean oxygenation during the late Ediacaran Period,
we measured the U and Mo isotope compositions of euxinic (anoxic and sulfidic) organic …

The oceanic biogeochemical cycles of the transition metals have been eliciting considerable
attention for some time. Many of them have isotope systems that are fractionated by key …

The emergence of oxygen-producing (oxygenic) photosynthesis fundamentally transformed
our planet; however, the processes that led to the evolution of biological water splitting have …

The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

Land to ocean transfer of material largely controls the chemical composition of seawater and
the global element cycles. Overall this transfer is dominated by the riverine transport of …

Molybdenum isotopes are increasingly widely applied in Earth Sciences. They are primarily
used to investigate the oxygenation of Earth's ocean and atmosphere. However, more and …

The concentration and isotope composition of molybdenum (Mo) in sediments and
sedimentary rocks are widely used proxies for anoxic conditions in the water column of …
