One of the big mysteries in the history of life is why it took so long time for complex organisms to evolve. The Earth is 4.5 billion years old and fossils of the first motile animals are ca. 555 million years old. It took 3,945,000,000 years or almost 4 million millennia before evolution in mostly microbial ecosystems evolved organisms with a capacity to […]
The relationship between Earth and life through time How Systems Paleobiology uses physiology as the conceptual bridge between paleobiological and geochemical data sets and provides us with a template for understanding global climate change and evaluation of the habitability of other planets. Professor Andrew H. Knoll, Fisher Professor of Natural History,Departments of Organismic and Evolutionary […]
The Reading Rainbow guy in Star Trek Next Generation was born blind, but able to see through his VISOR and, later on, via prosthetic ocular implants. By analogy, field geochemists now have new vision. Although, the device is not installed in a visor or as a prosthetic ocular implant, the new generation of energy-dispersive X-Ray […]
As a student in isotope geochemistry, the first words you will hear is “mass spectrometry”. Perhaps one day in the future, the first words will be “cavity-ring down spectrometry”. In a study led by David Balslev-Clausen, we measured carbon isotope compositions in rocks to compare the performance of conventional mass spectrometry and the brand new […]
