Researchers Show Evidence Of Common Mineral Capable Of Making, Breaking Bonds
2014-07-30 03:37:00

Arizona State University ASU team shows evidence for one mineral affecting the most fundamental process in organic chemistry: Carbon-hydrogen bond breaking and making Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth's deep carbon cycle, they provide energy for the deep biosphere, and may have implications for the origins of life. However, very little is known about how minerals influence organic reactions. A team of...

Classic Groundbreaking Experiment On Early Earth Peptides Replicated

Brett Smith for redOrbit.com - Your Universe Online [ Watch the Video: Stanley Miller’s Forgotten Experiments, Analyzed ] In a tribute to his old mentor and colleague, a marine chemistry professor at the University of California, San Diego was able to successfully replicate a mysterious and groundbreaking experiment by the “Father of Pre-biotic Chemistry.” In 1953, chemist Stanley Miller published a report on a landmark experiment that showed how peptides, basic building blocks...

Organic Conundrum In Milky Way’s Satellite Galaxy, The Large Magellanic Cloud
2014-06-23 03:03:26

Royal Astronomical Society A group of organic chemicals that are considered carcinogens and pollutants today on Earth, but are also thought to be the building blocks for the origins of life, may hold clues to how carbon-rich chemicals created in stars are processed and recycled in space. Scientists have studied how polycyclic aromatic hydrocarbons (PAHs) are created in an aging population of stars in the Milky Way’s satellite galaxy, the Large Magellanic Cloud. They have found that...

Bill Steigerwald, NASA's Goddard Space Flight Center Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts. "It is always difficult to put a value on the connection between meteorites and the origin of life; for...

New Study Outlines 'Water World' Theory Of Life's Origins
2014-04-16 11:27:36

Whitney Clavin, NASA's Jet Propulsion Laboratory Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet's living kingdoms. How did it all begin? A new study from researchers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and the Icy Worlds team at NASA's...

Did Life Originate At Deep Sea Vents?
2014-04-10 10:34:45

Woods Hole Oceanographic Institution One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility has grown in popularity in the last two decades - that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world. Recent research by...

Fuel Cells May Have Answers To The Rise Of Life
2014-03-14 10:32:15

NASA's Jet Propulsion Laboratory How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery. Researchers have simulated the conditions of an early Earth in test tubes, even fashioning some of life's basic ingredients. But how those ingredients assembled into living cells, and how life was first able to generate energy, remain unknown. A new study led by Laurie Barge of NASA's Jet Propulsion Laboratory in Pasadena, Calif.,...

Looking To Geology To Find Answers Of How Life On Earth Originated
2014-03-13 10:20:59

[ Watch the Video: The Origins of Life on Earth ] Brett Smith for redOrbit.com - Your Universe Online By simulating a geologic precursor of cell metabolism, a team of British and American scientists have taken an important step toward understanding how life arose on Earth. Their work is published in a new paper in the journal Astrobiology. “What we are trying to do is to bridge the gap between the geological processes of the early Earth and the emergence of biological life on this...

New Techniques Tease Out Building Blocks Of Life In Meteorites
2014-02-04 06:24:52

[ Watch the Video: New Technique For Studying Out-Of-This-World Particles ] Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long delved into the mysteries of the origins of life here on Earth and more recently have found evidence pointing to the skies above us. Some evidence has been found in material created in space and delivered to Earth via comets and meteors, containing the building blocks for life. The latest round of evidence comes by way of Michael...
