Latest Abiogenesis Stories
JUPITER, Fla., March 17 /PRNewswire/ -- Recent laboratory experiments which seek to recreate the formation of the first living cells from the basic chemical building blocks of nature are shedding new light on how life may have occurred on earth and on other planets, biologist Jack Szostak and chemist Brian Paegel said late yesterday in the annual Lasker Foundation Lecture on the Florida campus of the Scripps Research Institute. In his remarks, "The Origin of Cellular Life and the Emergence of...
Scientists at the Georgia Institute of Technology 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.
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.
Earth's chemical energy powered early life through 'the most revolutionary idea in biology since Darwin'.
A 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.
A team of researchers from the Astrobiology Centre (INTA-CSIC) 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.
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.
German scientists investigating the complex chemical mixture thought to be present in the early Earthâ€™s oceans have found that amino acids can be â€˜cookedâ€™ into many other important chemical building blocks of life when embedded in salt crusts.
Life on Earth came from other planets - So concludes a major scientific article which will appear in the inaugural issue of the online science journal, Cosmology.
Findings may provide insight into the origins of life on Earth, and even the search for life on Mars.
