SETI: To the Unknown, Full Speed Ahead

This year marks the 50th year of the search for extraterrestrial intelligence (SETI).  Seth Shostak, senior astronomer at the SETI Institute and one of its most outspoken spokesmen, made the cover of Sky and Telescope’s November 2010 issue.  He stands proudly over his Allen Telescope Array in his feature story, “Closing in on E.T.” celebrating […]

Life: Do Ingredients Imply Emergence?

Science articles continue to push the idea that if water is found somewhere, life is certain to emerge.  Other articles look for so-called “building blocks of life” or “ingredients for life,” implying or even plainly stating that life simply emerges from its parts.  While many have complained that this kind of thinking is as ridiculous […]

Probability Life Not Found on Exoplanet: 100%

Headlines are screaming that an earthlike planet in its star’s habitable zone has been found.  Many sources, though, are claiming that life must certainly exist on this planet.  Their hubris stems from the words of Steve Vogt, an astronomy professor at UC Santa Cruz.  “Personally, given the ubiquity and propensity of life to flourish wherever […]

Conjuring Up Evolutionary Implications from Current Data

What does observable reality imply about unobservable reality?  Some scientists say, a lot.  But is unobservable reality really real?  Or is it an oxymoron?  A couple of recent articles in the science media show scientists observing things in the present, then saying they have “huge implications” for things no scientist ever observed.     In […]

Grandma Gets Sexy Idea for Origin of Life

Helen Hansma likes being a grandmother and studying the origin of life, according to a video on PhysOrg.  To show she’s not over the hill, though, she came up with a sexy new hypothesis for how we got here: life emerged “between the sheets” – of mica.     Her video clip explains three parts […]

Wishing ET Upon a Star

What are the odds of finding extraterrestrials?  That subject has been discussed ad infinitum, but David Shiga at New Scientist thinks the odds just went up.  “Solitary suns like ours are not as rare as we once thought, boosting the likelihood that there are other life-friendly solar systems in the universe.”  It should be noted […]

Using Aliens to Titillate the Public

Geologists cannot even figure out our own planet (next headline), but some of them claim to know a lot about other planets – their geological history, and even their prospects for life.  Is it fair to tease the public with the L-word life when so much remains to be understood on the ground under our […]

The Limits of Scientific Speculation

How far can a scientist speculate and get a respectful hearing, just because he or she is a scientist?  One case to examine is a story on PhysOrg, “The Chance for Life on Io” (see also Astrobio.net).  Jupiter’s innermost large moon Io might be considered the last place to look for life.  It is the […]

Not Life on Titan Again

Something weird is going on at the large moon of Saturn.  “What is Consuming Hydrogen and Acetylene on Titan?” teased a press release from Jet Propulsion Laboratory”s Cassini mission: Two new papers based on data from NASA’s Cassini spacecraft scrutinize the complex chemical activity on the surface of Saturn’s moon Titan.  While non-biological chemistry offers […]

Fooling Around with OOL

Origin of Life (OOL) research is one of those areas in science where one doesn’t have to make any real progress, as long as he or she looks busy.  Anything the scientist says, no matter how speculative, or even foolish, is likely to be taken seriously, because the alternative – creation – has already been […]

Titan Continues to Surprise Saturn Scientists

Since reaching Saturn in 2004, the Cassini spacecraft has now made 68 flybys of Titan, the large smog-shrouded moon.  Space.com highlighted a recent picture showing the rings appearing to bisect the moon.  What are some of the latest findings of this alien world – the only moon in the solar system with a substantial atmosphere? […]

Southpaw Explanations Out of Left Field

All proteins are left handed.  Some humans are left handed.  Can evolution explain that?  Evolutionists are never known to be at a loss for words when asked to explain anything, provided they are allowed liberal use of the word perhaps.     A new projection theme for the first left-handed amino acids that comprise proteins […]

Noah’s Ark on Mars

We apologize for this improbable headline to draw attention to two stories making the rounds: new claims about Noah’s Ark on Mt. Ararat, and new claims about life on Mars.  Headlines on these topics show up periodically in the news.  What do the subjects have in common?  How do they differ?  Do the most recent […]

SETI and other Pointless Gimmicks

Astrobiologist Paul Davies sure knows how to ask interesting questions, and ruffle feathers in the process.  His new book about SETI, The Eerie Silence, reviewed by Leslie Mullen in Astrobiology Magazine, defaced some long-standing notions.  But are his suggestions any improvement?     Davies thinks the Voyager record was a “pointless gimmick.”  He thinks that […]

Life, an Elegantly Simple Mistake

The ribosome is a complex molecular machine made up of multiple protein and RNA parts.  Last year, winners of the Nobel Prize in Chemistry (see 10/10/2009) were praised for elucidating the structure and activity of ribosomes.  News stories described “the whole complicated process of transcription initiation, an operation that is of crucial importance in all […]
