Says Vakoch:

Might not such an attempt to put the best face on our current situation unintentionally reveal a potentially far more dangerous fault of humankind: a tendency to hide from our own problems and to avoid these threats to our very existence?

Here's the crux of Vakoch's argument, as far as I understand it: any interstellar society we encounter is likely to be much, much more advanced than us. After all, the chances of two cultures developing the ability to communicate across interstellar distances in the same part of the galaxy within the same historical moment are infinitessimal. So the aliens will either have been spacefaring for longer than us, or else their space-going era will already have ended — in which case we won't meet them.

So let's assume that a more advanced race, technologically, will also be more advanced in its cultural development. In that case, we'll be like messy, screamy, food-flinging, barfy children to these space demigods. And the most valuable contribution we could make to the interchange would be to remind our new friends of what it's like to be more primitive and id-driven. In any case, if we try to sweep our wars, our environmental destruction and our general crazoid behavior under the celestial rug, they'll probably be able to figure it out and we'll just look like idiots. Our best bet is just to emphasize everything bad about ourselves when we first meet other intelligences, so they'll know what they're in for.

Actually, Vakoch's argument veers sharply towards the end, and he starts talking about how acknowledging our "Shadow" (in the Jungian sense) is just good for us generally, and how we should just own up to our worse natures because it would be therapeutic and healthy. So maybe he's actually got some other agenda, and he's one of those Jungian infiltrators you hear about. [Space.com]

• The 1975 movie was based on the 1968 book of the same name by Alexander Key. Sadly, most of his novels, including Sprocket: A Little Robot and Bolts: A Robot Dog, are out of print. You can read and download some of these here.
• Don't let the name fool you, Escape To Witch Mountain isn't about witches at all, but about super-powered alien kids who don't know they're aliens.
• Remember the creepy and slightly spooky overture music? If not, you can hear it right here.
• In fact, want to watch the opening credit sequence? Well, here you go.
• Tony and Tia, the original Wonder Twins, both possess telekinesis, although Tony can only use it when he plays his harmonica. Tia can also telepathically speak to mammals, and to Tony. Looks like she got the lion's share of the cool stuff.
• Unlike Zan and Jayna, Tony and Tia have difficulty controlling their powers, which leads to several mishaps. Like Tia having to free every captive animal who can talk to her.
• Tony was played by Ike Eisenmann, who Trek fans will immediately recognize as Midshipman Peter Preston, who Scotty brings to the bridge of the Enterprise in Star Trek II: The Wrath of Khan. Perhaps if he'd taken the mortally wounded kid to sick bay, he might have survived.
• Kim Richards, who plays Tia, is the aunt of both Nicky and Paris Hilton, which isn't really that interesting, but more mind-boggling.
• Both Ike and Kim would be reunited as brother and sister in the extremely forgettable Devil Dog: The Hound of Hell TV movie in 1978.
• The Twins' Uncle Bene is played by Denver Pyle, better known as Uncle Jesse from The Dukes of Hazzard, which Kim Richards later appeared on as Cooter's daughter. Now that's just weird.
• They encounter Jason O'Day (Eddie Albert) who lives in a Winnebago and travels around the country. He ends up helping them out, and probably made kids everywhere think Winnebago's were cool. (I know it did for me, in fact my parents bought me a little scale model Winnie after I saw this movie).
• The bad guy in the movie, Aristotle Bolt, seems like a genial rich man who just want to save kids from the orphanage. Of course, he really wants the twins for their abilities. However, he does have a pretty cool name and lived in a replica of a Byzantine castle that was built by Templeton Crocker between 1926 and 1934 from lava rock from Mt. Vesuvius and materials gathered all over Europe.
• The twins eventually discover (via their little leather "star case") that they are actually aliens from a binary star system who fled to Earth because their own world was dying. They're reunited with others from their planet, and they fly off in their spaceship for the sanctuary of Witch Mountain, never to return.
• That is until Disney made a sequel, Return From Witch Mountain, in 1978. In this movie, Tony and Tia have been training hard to use their powers and to learn about their own kind. In fact, they've been working so hard that the elders let them have a vacation in Los Angeles. What, two superkids on a vacation in L.A.? Nothing could possibly go wrong, right?
• If you want to see a movie trailer that says 1970s as loud of possible, then you're in for a treat. This trailer for Return features Christopher Lee, Bette Davis, andthe words "far out," "molecular mobilization," and "intergalactic energization." Is it me, or does that announcer sound like the guy from the old Batman TV show?
• In the sequel, Christopher Lee plays evil mad scientist Dr. Victor Gannon, and he uses a mind-control device he's invented on Tony, eventually pitting twin against twin in a battle of telekinesis. Bette Davis plays Letha Wedge (what a name), who has been financing the bad doctor's experiments.
• Sadly, there's no Eddie Albert in the sequel. It was also Jack Soo's final film, having been best known for playing Det. Sgt. Nick Yemana on Barney Miller. It was probably the coffee.
• In 1982 Disney made a television pilot called Beyond Witch Mountain, which featured a return of Eddie Albert as Jason and his Winnebago, but they recast everyone else, from the kids all the way to down to Aristotle Bolt. This was meant to become an ongoing series with the kids and Jason finding other alien kids and helping them get back home, but it never got that far and never went to series.
• Disney remade the original film back in 1995, with some major changes to the script. The twins are now named Danny and Anna, and they are separated as infants (who have full-fledged telekinesis), but are later reunited accidentally when they're older. Land developer Edward Bolt (the always evil Robert Vaughn) finds out about their powers, and plans to use them to blow up the entrance to Witch Mountain... without explosives. Way to use that power, Edward.
• It wasn't as charming as the original movie, and wasn't nearly as well received. You can find out why by watching the first 10 minutes right here.

According to an early release about her scientific paper:

Scientists have long known that most compounds in living things exist in mirror-image forms. The two forms are like hands; one is a mirror reflection of the other. They are different, cannot be superimposed, yet identical in their parts.

When scientists synthesize these molecules in the laboratory, half of a sample turns out to be "left-handed" and the other half "right-handed." But amino acids, which are the building blocks of terrestrial proteins, are all "left-handed," while the sugars of DNA and RNA are "right-handed." The mystery as to why this is the case, "parallels in many of its queries those that surround the origin of life," said Pizzarello.

Years ago Pizzarello and ASU professor emeritus John Cronin analyzed amino acids from the Murchison meteorite (which landed in Australia in 1969) that were unknown on Earth, hence solving the problem of any contamination. They discovered a preponderance of "left-handed" amino acids over their "right-handed" form.

"The findings of Cronin and Pizzarello are probably the first demonstration that there may be natural processes in the cosmos that generate a preferred amino acid handedness," Jeffrey Bada of the Scripps Institution of Oceanography, La Jolla, Calif., said at the time.

The new PNAS work was made possible by the finding in Antarctica of an exceptionally pristine meteorite. Antarctic ices are good "curators" of meteorites. After a meteorite falls — and meteorites have been falling throughout the history of Earth — it is quickly covered by snow and buried in the ice. Because these ices are in constant motion, when they come to a mountain, they will flow over the hill and bring meteorites to the surface.

"Thanks to the pristine nature of this meteorite, we were able to demonstrate that other extraterrestrial amino acids carry the left-handed excesses in meteorites and, above all, that these excesses appear to signify that their precursor molecules, the aldehydes, also carried such excesses," Pizzarello said. "In other words, a molecular trait that defines life seems to have broader distribution as well as a long cosmic lineage."
