Modern Adaptation Of Miller-Urey Origin Of Life Experiments
2014-01-21 13:05:47

[ Watch The Video: Conducting Miller-Urey Experiments ] The Journal of Visualized Experiments Today, January 21, JoVE, the Journal of Visualized Experiments, published a modern approach to a famed experiment that explored one of the most intriguing research questions facing scientists today—the origin of life on earth. The protocol, titled Conducting Miller-Urey Experiments, is comprised of a modern and simplified approach to the method used by Dr. Stanley Miller and Dr....

A team of Massachusetts General Hospital (MGH) investigators working to create "protocells" – primitive synthetic cells consisting of a nucleic acid strand encased within a membrane-bound compartment – have accomplished an important step towards their goal. In the November 28 issue of Science, the investigators describe a solution to what could have been a critical problem – the potential incompatibility between a chemical requirement of RNA copying and the stability of the protocell...

Minerals Were Scarce When Life First Formed On Earth: Study
2013-11-26 08:05:20

redOrbit Staff & Wire Reports - Your Universe Online Just eight percent of the nearly 5,000 different types of minerals currently found on Earth were present on or near the planet’s surface when life first originated, according to new research published in the latest edition of the American Journal of Science. According to researchers from the Carnegie Institution for Science, life came about as a result of natural processes that took advantage of raw materials available during...

Clay May Have Been Cradle Of Life
2013-11-08 11:08:34

[ Watch the Video: Life On Earth May Have Come From Clay ] Brett Smith for redOrbit.com - Your Universe Online Often viewed as an apparently infertile blend of various minerals, clay might have actually been the birthplace of life on Earth, biological engineers from Cornell University report in new research appearing in Thursday’s online edition of the journal Scientific Reports. The study authors set out to simulate ancient seawater in order to analyze the properties of clay under...

Was Life On Earth Jump-Started By Icy Comet Impact?
2013-09-16 07:00:57

[ Watch the Video: Comets May Have Provided Earth The Building Blocks Of Life ] Lawrence LeBlond for redOrbit.com - Your Universe Online An international group of scientists has discovered that life on Earth may have been jump-started when icy comets bombarded the planet billions of years ago. Scientists from University College London, the University of Kent and Lawrence Livermore National Laboratory have published a paper, appearing on the Nature Geosciences website on September 15....

Sutter's Mill Meteorite Considered Scientific Gold
2013-09-11 05:44:09

April Flowers for redOrbit.com - Your Universe Online Researchers from Arizona State University (ASU) have made an important discovery about the possible inventory of molecules available to the early Earth. Sandra Pizzarello, a research professor in ASU's Department of Chemistry and Biochemistry, led the team in examining the Sutter's Mill meteorite - which exploded in a blazing fireball over California last year - to find that it contains organic molecules not previously found in any...

New Computational Approaches Speed Up Exploration Of The Universe
2013-09-05 11:52:32

University of Southern Denmark How many different molecules can be created when you release one of the universe's most reactive substances, hydrogen cyanide, in the lab? And will the process create some particularly interesting molecules? That is what scientists call a good question, because hydrogen cyanide seems to have played a role in creating some of life's building blocks. Hydrogen cyanide is an organic compound and it is found in large quantities in the universe. It may have...

New Evidence Suggests Earthlings Started Life As Martians
2013-08-29 07:02:33

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long posited life on Earth may have started somewhere else in the universe, many pointing to the Red Planet. Now, new evidence is emerging that may hold some truth to that long-debated theory. Professor Steven Benner, from the Westheimer Institute for Science and Technology, gave a speech today at the Goldschmidt 2013 conference in Florence, Italy describing how life on Earth may have kickstarted on Mars. Benner...

Near-optimal Genetic Code Model Created By Researchers
2013-08-29 04:15:01

redOrbit Staff & Wire Reports - Your Universe Online By creating a model of genetic code evolution, researchers have discovered new information about how RNA signaling could have developed into the “near-optimal” modern genetic code. Lead author Justin Jee, a doctoral student at NYU School of Medicine, and colleagues set out to account for the composition of the genetic code, which makes it possible for proteins to be constructed from amino acids with high specificity based on...

Origins Of Life On Earth May Help Hunt For Life On Other Planets
2013-07-31 10:19:02

Brett Smith for redOrbit.com - Your Universe Online Tracing the origins of life isn't only central to understanding our own history, it can also be important for discovering life on other planets. Two recently published papers -- 'Beating the acetyl coenzyme A-pathway to the origin of life' and 'The inevitable journey to being' -- in the Philosophical Transactions of the Royal Society B add supporting details to the theory life on Earth began near hydrothermal vents in the ocean floor....


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
