Who’s Out There?—In the Colorado River2 min read

Since it’s been so difficult to re-invent life on Earth using wet technology, we shouldn’t ignore the weird inventions Time and Mother Nature have come up with here. Like, who would expect to find a whole new type of life in the Colorado River?

One estimate suggests these new life forms will add 50% more phyla to our catalogs of mini-life. They are tiny, 0.1-0.2 microns wide, round and hairy. They function with only one million base pairs of short RNA. (E. coli has 5 million.) And they don’t grow in the lab as expected. They use fermentation for energy and need help making nucleotides and amino acids, which means they are dependent on other organisms for these “…basic biosynthetic pathways.” (Nature July 9, 2015.) Screening the river found these mini-critters. They were missed by the usual 16SrRNA searches. Quanta magazine.org asks: are they invaders from outer space? Or simply a proto-RNA? Could they provide some clue to the complex processes required to trigger life-forms on Earth and elsewhere, life-forms stable enough to evolve?

As we’ve noted before, RNA is considered by some to be the most likely molecule that started the whole business of  living. It not only participates in building the amino acids we need. Its four bases (AGUC), phosphate and sugar structure provides needed coding, while also acting as a catalyst to speed up and enable life’s essential chemical reactions. The bottom line seems to be that the necessary components to get life started need to emerge at the same time and same place, as they did on Earth some 4 billion years ago.

Those three necessary components are

1)genetic material that carries information,

2) proteins, and

3) a protective cellular structures.

Building blocks for all three components have been seen in primordial chemical reactions using electrons. Biochemists have seen carbon compounds and ultraviolet light produce 12 amino acids, uracil and cytosine nucleotides. The latter two are found in RNA, which now seems to exist in many forms we didn’t imagine a decade ago. RNA may have some more surprises for us. Meanwhile, we’ll keep watch on our near-twin, elder planet, Kepler 452b, as our new telescopes come online and begin sniffing such planets’ atmosphere for signs of life and SETI looks for sentience out there.

Cary Neeper

Cary Neeper is an avid student of complexity theory, sustainability, steady-state economics, and the impact of cosmology on issues of science and religion. She grew up in the foothills of Hayward, California, where she helped rack dried fruit on her father’s 40-acre apricot ranch. After studying zoology/chemistry and religion at Pomona College and medical microbiology at the University of Wisconsin, she moved with her husband to northern New Mexico, where they raised their family. The Neepers still live in the Southwest with a friendly menagerie of dogs, fish, chickens, geese, ducks and a turkey called Little Bear. Cary plays string bass with local folk, symphony and jazz groups and tennis with local retired physicists. She paints landscapes in acrylics, including the cover art for her first Penscript title, The Webs of Varok.

Cary's first novel and Webs of Varok prequel A Place Beyond Man was originally published in 1975 by Charles Scribner’s Sons, Dell, and Millington, London. Cary re-released A Place Beyond Man as an Author’s Guild Backinprint edition, now available from online booksellers. Its themes of sustainability and interspecies cooperation have now grown into new adventures for its human, elll and varok family as they travel the alternate 21st century Solar System in the five-volume Archives of Varok, coming from Penscript Publishing House in 2012–2014. Cary’s other works include two musical science fiction comedies “U.F.F.D.A.!” and “Petra and the Jay,” as well as newspaper and magazine articles, essays, short stories, and book reviews for The Christian Science Monitor.
