NO BIO-STARTER BREW. "But will it be possible to make an organism using just the genomic information obtained from an extinct species alone, with no material from a modern species? Would this result in a living organism? Here his answer was “No.” http://lnkd.in/dSrVBvg View in LinkedIn

MICROPROPAGATION. "Flowers regenerated from 30,000-year-old frozen fruits ... While animals are still difficult to clone, cloning plants is a far different matter. If you have a clean piece of living tissue, even a very tiny one, putting it in a sterile petri dish with the right combination of plant hormones can cause it to sprout roots, leaves, or both." http://scifi.stackexchange.com/questions/34304/how-did-they-bring-the-plants-back-from-extinction View in LinkedIn

FIRST DE-EXTINCTION METHOD, "both involve injecting a surrogate egg with the target species’ DNA. The first method is in vitro fertilization of the egg using frozen sperm ... produces a hybrid between two species ... only a viable option if the target species’ and the egg donor species’ DNA are similar enough to produce a viable embryo ... By backcrossing hybrid offspring, breeders could then produce a more pure lineage over time." http://lnkd.in/dMx5dtr View in LinkedIn

SECOND DE-EXTINCTION METHOD "is by pure cloning: emptying the surrogate egg of its own DNA, and injecting it with a copy of the target species’ genome. There are two potential sources of such a genome: researchers can use well preserved ... somatic cells ... or they can build the genome ... No species has yet been cloned with reconstructed DNA, but for long-gone species it might be our best shot." http://lnkd.in/dMx5dtr View in LinkedIn

ANCIENT DNA AND DE-EXTINCTION. "Church’s genome-retooling method could theoretically work on any species with a close living relative and a genome capable of being reconstructed." http://lnkd.in/d2ieE9w View in LinkedIn

DE-EXTINCTION OF ANCIENT VIRUSES: "Scientists have recreated other pathogenic viruses in the laboratory, including a SARS-like virus and the formerly extinct strain of influenza virus responsible for the 1918-19 “Spanish Flu” pandemic, which is estimated to have infected a third of the world population and killed three to five percent." http:/http://lnkd.in/dzX9u4Z View in LinkedIn

RESURRECTION OF A 30,000 YEAR OLD DORMANT VIRUS "Pithovirus sibericum, was resurrected from Siberian permafrost that was, surprisingly, still infective. "This is the first time we've seen a virus that's still infectious after this length of time." http://lnkd.in/dF_rGWthttp:/http://lnkd.in/dzX9u4Z View in LinkedIn

EXTINCT FUNGI REVIVED. "Some fungi remain viable for over 100,000 years in ice. This leads to the possibility that a species can appear to become extinct, but may be capable of reappearing at a later point in time." http://lnkd.in/dhvpdkg View in LinkedIn

ANCIENT PLANT REVIVED. "A team of scientists from the ... Russian Academy of Sciences, has successfully revived a flowering plant from a 32,000-year-old fruit buried in Siberian permafrost." They used tissue culture and clonal micro-propagation techniques. http://lnkd.in/dghi2CG View in LinkedIn

ANCESTRAL GENE RESTORATION. "Ancient genes can now be reconstructed, expressed and functionally characterized, thanks to improved techniques for inferring and synthesizing ancestral sequences. This approach, (is) known as 'ancestral gene resurrection'." http://www.nature.com/nrg/journal/v5/n5/abs/nrg1324.html View in LinkedIn
