Who’s Out There?—Focusing On Talent3 min read

Complex critters are pretty clever. I’ve enjoyed watching David Attenborough and his “Planet Earth II,” in which he shows us some of the cleverness we may have overlooked:A fish sweeps up some debris, finds a clam, takes it to a round coral
and throws it again and again at the coral until it breaks open. Big dragon lizards bite an ox and wait weeks for it to die of the poison. Hippos in rivers and turtles on a coral shelf return to the same locale so fish can find them and clean their skin of small invaders.

Perhaps more amazing than these examples of living genius is the recently discovered trap that bacteria have “invented” in order to protect themselves from viruses. Somehow, sometime long ago, bacteria added a few repetitive genes to their genome. These repetitive genes were clustered, regularly interspersed, short, palindromic repeats of DNA (CRISPR).

They were first observed in E.coli bacteria in 1987 and again in 1993. Those repetitive sequences were recognized as being similar to the DNA of bacteriaphage, viral enemies of bacteria. The bacteria had copied them as traps, a kind of immunological memory, to fight off the similar invading viruses—the bacteriaphage. By adding the repeating virus-like DNA to their own genome, the bacteria could react faster to another attack of the virus, the way vaccination works in us.

During an attack, the bacteria copies the phage DNA, turns it into RNA that its enzyme Cas9 can destroy. (Cas 9 is not active unless it is bound to that “guide” RNA. This means that CRISPR/Cas9 can find specific genes (ie specific pieces of DNA) and try to repair them until a mistake is made and the gene is “knocked out.”

This is an amazing example of survival tactics at the molecular level. It raises the stakes big time for betting on life evolving wherever it gets half a chance. And half a chance may be all that our local solar system moons can manage, but we’ll soon know, if all goes well in the next decade or so.

Meanwhile, read Ben Miller’s book The Aliens Are Coming—The Extraordinary Science Behind Our Search For Life in the Universe, New York, the Experiment, 2016. Notice the subtitle. The author, a “mutant ape,” is a realist, as well as a “Comedian,” a brilliant writer who entertains us as he takes us into the complexity of life’s possible beginnings and how we are learning with “…technological marvels
returning unprecedented amounts of data…” that we may indeed NOT be alone in this universe.

Miller’s short sections, labeled with bold titles, help explain the nuances and intricacies of chemistry, astronomy and astrophysics, beginning with theories of how life may have started on Earth and how we might detect its presence in the exoplanets we are finding throughout our galaxy. Thrown in the text are lively explanations of entropy, earth’s extremeophiles, our oceans’ hydrothermal vents, space travel realism, Earth’s continental drift and the “aliens” it produced on
separated islands and the later convergence of animal intelligence in “completely different kinds of brains. (Example: apes and crows are both puzzle solvers.)

In short, I highly recommend this book to astronaut.com readers. Just be fore-warned: Ben Miller’s wit can catch you sideways. Better not take the title of the book seriously.

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.
