Journal ArticleDOI
Carbonaceous meteorites contain a wide range of extraterrestrial nucleobases
Michael P. Callahan,Karen E. Smith,H. James Cleaves,Josef Ruzicka,Jennifer C. Stern,Daniel P. Glavin,Christopher H. House,Jason P. Dworkin +7 more
TL;DR: The results demonstrate that the purines detected in meteorites are consistent with products of ammonium cyanide chemistry, which provides a plausible mechanism for their synthesis in the asteroid parent bodies, and strongly supports an extraterrestrial origin.
Journal ArticleDOI
Primordial synthesis of amines and amino acids in a 1958 Miller H2S-rich spark discharge experiment
Eric T. Parker,H. J. Cleaves,Jason P. Dworkin,Daniel P. Glavin,Michael P. Callahan,Andrew D. Aubrey,Antonio Lazcano,Jeffrey L. Bada +7 more
TL;DR: The relative yield of some amino acids, in particular the isomers of aminobutyric acid, are the highest ever found in a spark discharge experiment, suggesting that H2S may have played an important role in prebiotic reactions in early solar system environments.
Journal ArticleDOI
Origin and Evolution of Prebiotic Organic Matter As Inferred from the Tagish Lake Meteorite
Christopher D. K. Herd,A. Blinova,Danielle N. Simkus,Yongsong Huang,Rafael Tarozo,Conel M. O'd. Alexander,Frank Gyngard,Larry R. Nittler,George D. Cody,Marilyn L. Fogel,Yoko Kebukawa,A. L. David Kilcoyne,Robert W. Hilts,Greg F. Slater,Daniel P. Glavin,Jason P. Dworkin,Michael P. Callahan,Jamie E. Elsila,Bradley T. De Gregorio,Rhonda M. Stroud +19 more
TL;DR: A systematic study of variations in the mineralogy, petrology, and soluble and insoluble organic matter in distinct fragments of the Tagish Lake meteorite finds that the variations correlate with indicators of parent body aqueous alteration.
Book
The Effects of Parent Body Processes on Amino Acids in Carbonaceous Chondrites
TL;DR: Results are consistent with the theory that aqueous alteration played an important role in amplification of small initial left handed isovaline excesses on the parent bodies.
Journal ArticleDOI
Early Neolithic wine of Georgia in the South Caucasus
Patrick McGovern,Mindia Jalabadze,Stephen Batiuk,Michael P. Callahan,Karen E. Smith,Gretchen R. Hall,Eliso Kvavadze,David Maghradze,Nana Rusishvili,Laurent Bouby,Osvaldo Failla,Gabriele Cola,Luigi Mariani,Elisabetta Boaretto,Roberto Bacilieri,Patrice This,Nathan Wales,David Lordkipanidze +17 more
TL;DR: The earliest biomolecular archaeological evidence for grape wine and viniculture from the Near East, at ca. 6,000-5,800 BC, was provided by as mentioned in this paper.
