Paleobiology & Biosignatures: November 2013


An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant resins.

Reconstructing the rise of life during the period of Earth's history when it first evolved is challenging. Earth's oldest sedimentary rocks are not only rare, but also almost always altered by hydrothermal and tectonic activity.

Biosignatures Across Space and Time

This meeting will to bring together astronomers, geologists, biologists and other interested scientists to share interdisciplinary approaches to detect signs of life on early Earth and other celestial bodies (including exoplanets) and to elucidate the environmental limits and origins of life.

Clay May Have Been The Birthplace of Life

Clay, a seemingly infertile blend of minerals, might have been the birthplace of life on Earth. Or at least of the complex biochemicals that make life possible, Cornell University biological engineers report in the Nov. 7 online issue of the journal Scientific Reports, published by Nature Publishing.
