Ice To See You: 30,000-Year-Old Flower Revived (via Simon Reames) update from earlier post

Fruit and seeds hidden in an Ice Age squirrel's burrow in Siberian permafrost have been resurrected into a flower by Russian scientists.

Using a pioneering experiment, the Sylene stenophylla has become the oldest plant ever to be regrown and it is fertile, producing white flowers and viable seeds.
The seeds date back 30,000 to 32,000 years and raise hopes that iconic Ice Age mammals like the woolly mammoth could also eventually be resurrected.
The researchers, who published their findings in Proceedings of the National Academy of Sciences in the US, said the results prove that permafrost serves a natural depository for ancient life forms.
"We consider it essential to continue permafrost studies in search of an ancient genetic pool, that of pre-existing life, which hypothetically has long since vanished from the earth's surface," the scientists said in the article.

Ancient plants back to life after 30,000 frozen years

Scientists in Russia have grown plants from fruit stored away in permafrost by squirrels over 30,000 years ago.
The fruit was found in the banks of the Kolyma River in Siberia, a top site for people looking for mammoth bones.
The Institute of Cell Biophysics team raised plants of Silene stenophylla - of the campion family - from the fruit.
Writing in Proceedings of the National Academy of Sciences (PNAS), they note this is the oldest plant material by far to have been brought to life.
Prior to this, the record lay with date palm seeds stored for 2,000 years at Masada in Israel.
The leader of the research team, Professor David Gilichinsky, died a few days before his paper was published.
In it, he and his colleagues describe finding about 70 squirrel hibernation burrows in the river bank.
