Russian scientists resurrection frozen for more than 30000 years seeds

In a corner of the Russian museum in a basin was planted stenophylla feetnor plants of the genus of grass, although in the wild also have this kind of plant growth, but the museum in this plant is quite different, because it has deep sleep tens of thousands of years.
More than 30000 years ago, stenophylla seed was buried the squirrels in Siberia in permafrost, cold for seed life process press the stop button. Now, it to reopen, blossom a white flower, can be the world's oldest and most vital more living cells.
Scientists say, low temperature permafrost is like a "gene cold storage". Stenophylla "resurrection" means that some early life forms--" those early of the earth from the biological "can be cheap new era hats frozen wasteland in died immortality. This also means that, if be in Mars or other cold planet found dormant life, the life is also likely to recovery.
This kind of plant seeds feetnor grass from the arctic ground squirrel fossils discount nfl jerseys found in the cave, these small animals in the ice age was active in the desolate tundra, roughly in Russia is now the eastern Siberia KeLeiMaHe nearby. At the time of homo sapiens and later extinct mammoth, Neanderthal man (paleoanthropology, is in the form of a department with modern parallels the other department group) share the world.
At high magnification with microscope, these seeds was identified as the grass plants of the stenophylla feetnor fruit. The fruit buried 125 feet (38.1 meters) below the environment, with the appearance of the seeds stenophylla relative now slightly smaller.
The radiocarbon tests showed that the seed that tens of thousands of years old with a long life (31500-32100). The researchers say, because the food of ice storage squirrel wedge (by surface water into the gap of periodic again to freeze, expanding for ice and fissure filling body, in profile wedge shape as phenomenon) and frozen sediment encircle, one of the storage things will soon frozen and won't thaw out.
The study's lead, Moscow frozen hydrology laboratory Gilichinsky professor explanation says, the freezing sediment from geology said late pleistocene (dating from about 20000 years ago, the characteristics of the pleistocene glacier is active role), a temperature of minus seven degrees Celsius, sediment never thaw out.
Researchers in a sterile environment through the most advanced technology to foster and planting the seeds of tens of thousands of years ago, the technology can be in a relatively short period of time, from a single individual to cultivate a large number of plants. With "the body breeding" technology, the researchers discovered the seeds from the extract and make stenophylla placental tissue in the laboratory in reproducing POTS of vitality, the spawning, blossom and bear fruit, and the new seeds, but it bears could continue to breed.
