Unselfish molecules may have helped give birth to the genetic material of life (3/9/2010)

Unselfish molecules may have helped give birth to the genetic material of lifeOne of the biggest questions facing scientists today is how life began. Scientists at Georgia Tech have discovered that small molecules could have acted as "molecular midwives" in helping the building blocks of life's genetic material form long chains and may have assisted in selecting the base pairs of the DNA double helix. ...> Full Article



Scientists create tiny RNA molecule with big implications for life's origins (2/24/2010)

Scientists create tiny RNA molecule with big implications for life's origins An extremely small RNA molecule created by a University of Colorado at Boulder team can catalyze a key reaction needed to synthesize proteins, the building blocks of life. The findings could be a substantial step toward understanding "the very origin of earthly life," the lead researcher contends. ...> Full Article


New research rejects 80-year theory of 'primordial soup' as the origin of life (2/4/2010)

For 80 years it has been accepted that early life began in a "primordial soup" of organic molecules before evolving out of the oceans millions of years later. Today the "soup" theory has been over turned in a pioneering paper in BioEssays which claims it was the Earth's chemical energy, from hydrothermal vents on the ocean floor, which kick-started early life. ...> Full Article


What came first in the origin of life? A study contradicts the 'metabolism first' hypothesis (1/10/2010)

Research published in Proceedings of National Academy of Sciences rejects the theory that the origin of life stems from a system of self-catalytic molecules capable of experiencing Darwinian evolution without the need of RNA or DNA and their replication. The research, which was carried out with the participation of Mauro Santos, researcher of the Department of Genetics and Microbiology at Universitat Autònoma de Barcelona. ...> Full Article



Prussian blue linked to the origin of life (12/15/2009)

Prussian blue linked to the origin of lifeA team of researchers from the Astrobiology Centre has shown that hydrogen cyanide, urea and other substances considered essential to the formation of the most basic biological molecules can be obtained from the salt Prussian blue. In order to carry out this study, published in the journal Chemistry & Biodiversity, the scientists recreated the chemical conditions of the early Earth. ...> Full Article


Just like old times: Generating RNA molecules in water (11/22/2009)

A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. Now, in a study appearing in this week's JBC, researchers in Italy have reconstructed one of the earliest evolutionary steps yet: generating long chains of RNA from individual subunits using nothing but warm water. ...> Full Article
