Origin of life: Sulfur was mission critical, some insist

Here: A fresh look at forgotten vials from Stanley Miller’s primordial-soup-in-a-bottle experiments implies that volcanoes seeping hydrogen sulfide helped form some of life’s earliest ingredients.  Earth’s early atmospheric conditions aren’t known, and the reactions in this experiment could only have happened near a source of sulfur. On a primordial Earth, that would have meant volcanoes. […]

Evidence for earliest life is evidence for strongest imagination, say astrobiologists

Astrobiology Magazine, (not the source you’d expect), offers MSNBC a word of caution re fossils of early life: However, the interpretation of the structures has always been controversial, and it is still hotly debated among scientists searching for Earth’s earliest evidence for life. Specimens from the site apparently displayed branching structures that some researchers said […]

Coffee!! Who’s the Man from Mars? You’s the Man from Mars!

David L. Chandler asks, Are we all Martians? According to many planetary scientists, it’s conceivable that all life on Earth is descended from organisms that originated on Mars and were carried here aboard meteorites. If that’s the case, an instrument being developed by researchers at MIT and Harvard could provide the clinching evidence.- “Are you […]

Origin of life: John “End of Science” Horgan offers a momentous secret for us all to keep

“Pssst! Don’t tell the creationists, but scientists don’t have a clue how life began” (Scientific American, Feb 28, 2011) : Exactly 20 years ago, I wrote an article for Scientific American that, in draft form, had the headline above. My editor nixed it, so we went with something less dramatic: “In the Beginning…: Scientists are […]

Craig Venter denies common descent — Dawkins incredulous

Interesting story at Evolution News & Views about an exchange between Craig Venter (of human genome fame) and Richard Dawkins (of neo-atheist fame). Venter denies common descent, Dawkins can’t believe that he would even question it. For the exchange, which also includes Paul Davies, go here (start at the 9 minute mark). Origin-of-life researchers such as […]

Comments from contacts about the possible alien life form discovery

In response to someone who wondered whether American scientists might be letting their imaginations run away with them about this spectacular new alien life find, Rob Sheldon offers “absolutely not”. Au contraire, the French were onto it and NASA dropped the ball. On why that happened, he says, NASA’s attitude is an example of … […]

From the Origin of life news desk: Ammonia from meteors kickstarted life

From New Scientist, we learn “Meteorite cargo could solve origin-of-life riddle” (01 March 2011) Andy Coghlan because A chemical vital for life on Earth may have arrived ready-made from space. Unexpectedly, a chondritic meteorite has been found to contain large amounts of ammonia, a nitrogen-rich chemical needed to form the basic building blocks of life, […]

Origin of life theories: Life from vessels of clay?

We learned recently that “Clay-Armored Bubbles May Have Formed First Protocells: Minerals Could Have Played a Key Role in the Origins of Life” (ScienceDaily, Feb. 7, 2011): A team of applied physicists at Harvard’s School of Engineering and Applied Sciences (SEAS), Princeton, and Brandeis have demonstrated the formation of semipermeable vesicles from inorganic clay.The research, […]

Is Craig Venter’s Synthetic Cell Really Life?

Bioethicist Gregory Kaebnick, Ph.D., has an interesting take on the recently announced synthetic cell created by a team of researchers led by J. Craig Venter at the J. Craig Venter Instititute (JVCI). In a recent article in The Scientist entitled Is the “Synthetic Cell” about Life?, Kaebnick writes: …the technical accomplishment is not quite what […]

Zettabytes – by Chance or Design?

A new measure of information has been invented – the Zettabyte = 1,000,000,000,000,000,000,000 bytes, or 10^21 bytes. Zettabytes overtake petabytes as largest unit of digital measurement Heidi Blake, 4 May 2010, The Telegraph UK “The size of the “digital universe” will swell so rapidly this year that a new unit – the zettabyte – has […]

How were RNA gene repeats, “essential” to DNA repair, formed?

RNA replications have now been discovered to be “essential” to DNA error correction systems. If they are “essential”, how could they arrive by random mutation and “selection”? On what basis does neoDarwinism predict error correction in the first place? From Intelligent Design, methodology one expects to see evidence of design in complex biochemical systems. From […]
