NASA scientists analyzing the dust of meteorites have discovered new clues to a long-standing mystery about how life works on its most basic, molecular level. We found more support for the idea that biological molecules, like amino acids, created in space and brought to Earth by meteorite impacts help explain why life is LEFT-HANDED," said Dr. Daniel Glavin of NASA's Goddard Space Flight Center in Greenbelt, Md. "By that I mean why all known life uses only left-handed versions of amino acids to build proteins." Glavin is lead author of a paper on this research appearing in the Proceedings of the National Academy of Sciences March 16.

Another “just-so” story. It takes a great imagination to be a scientist these days.
You too dear heart, thanks.

The Cycle of Cosmic Catastrophes:
Flood, Fire, and Famine
in the History of Civilization
by Richard Firestone,
Allen West, and
Simon Warwick-Smith
All right! A threeway. I would say, “Thank my Lucky Stars” to stay on thread, or “Thank my Lucky Charms” in the Spirit of the St. Paddy Day, but I don’t feel like being clubbed with the Holy Writ right now. I might spill muh beer.
Thanks for the pings. Interesting.
Yet like SETI, they have yet to find anything. This isn’t a new mystery, it’s haunted biochemists for ages. I don’t have a problem with there being alien life, I don’t even have a problem with there being D-amino and/or L-sugar life, but unlike researches who go to the extremes of pushing the question back with psuedo-panspermia theories, the lack of evidence for these things doesn’t bother me. These researchers MUST come up with an answer for the lack of evidence because their world view demands it.
I knew God was left-handed! All the best people are :P
3 new bacteria species found (not on earth, either...)
