Cloning Of Dinosaurs And Ancient Animals Proven Impossible

Humanity will never be able to resurrect the creatures of long ago. New research suggests that even under ideal conditions, DNA becomes unreadable after a mere 1.5 million years. Thus all the dino bones and amberized insects in the world are useless for cloning purposes, Scientific American writes:

Palaeogeneticists led by Morten Allentoft in Perth, Australia, examined 158 DNA-containing leg bones belonging to three species of extinct giant birds. By comparing the specimens’ ages and degrees of DNA degradation, the researchers calculated that DNA has a half-life of 521 years. That means that after 521 years, half of the bonds between nucleotides in the backbone of a sample would have broken; after another 521 years half of the remaining bonds would have gone; and so on.

The team predicts that even in a bone at an ideal preservation temperature of −5 ºC, effectively every bond would be destroyed after a maximum of 6.8 million years.

Cloned Horses Allowed To Compete In The Olympics

It won’t be long before the basketball championship consists of an American squad of Michael Jordan clones squaring off against a foreign squad of Michael Jordan clones with pencil mustaches. Slate reports:

Reversing an earlier ban, the international governing body for equestrian sports has decided that cloned horses can compete alongside their traditionally bred counterparts.

“The FEI will not forbid participation of clones or their progenies in FEI competitions,” the Federation Equestre Internationale said after its June meeting in Lausanne, Switzerland, according to The Chronicle of the Horse. “The FEI will continue to monitor further research, especially with regard to equine welfare.”

That’s good news for two companies—ViaGen in Texas and Cryozootech in France—that have successfully cloned champion horses, mainly for breeding purposes. Cryozootech has produced two clones of the American show-jumping champion Gem Twist. ViaGen, which owns the rights to the technology that produced the famous cloned sheep Dolly, has cloned several horses.

Scientists To Clone Wooly Mammoth

mammoth_landscapeA cloned pet baby mammoth — Christmas gift craze of the year for 2018. CNN reports:

A team of scientists from Japan, Russia and the United States hopes to clone a mammoth, a symbol of Earth’s ice age that ended 12,000 years ago, according to a report in Japan’s Yomiuri Shimbun. The researchers say they hope to produce a baby mammoth within six years.

The scientists say they will extract DNA from a mammoth carcass that has been preserved in a Russian laboratory and insert it into the egg cells of an African elephant in hopes of producing a mammoth embryo.

The team is being led by Akira Iritani, a professor emeritus at Kyoto University in Japan. He has built upon research from Teruhiko Wakayama of Kobe’s Riken Center for Developmental Biology, who successfully cloned a mouse from cells that had been frozen for 16 years, to devise a technique to extract egg nuclei without damaging them, according to the Yomiuri report.

South Korean Scientists Clone Beagle That Glows Fluorescent Green

Could Tegon, the glowing dog, be the key to finding cures for many human diseases? Via Reutuers:

South Korean scientists said on Wednesday they have created a glowing dog using a cloning technique that could help find cures for human diseases such as Alzheimer’s and Parkinson’s, Yonhap news agency reported.

A research team from Seoul National University (SNU) said the genetically modified female beagle, named Tegon and born in 2009, has been found to glow fluorescent green under ultraviolet light if given a doxycycline antibiotic, the report said.

First Cloned Cat Turns Ten Years Old

Cat Clone AnniversaryIt feels like just yesterday that the first generation of cloned animals captured the headlines — now they are passing comfortably into old age (without any bizarre mutations, eyeballs spontaneously falling out, et cetera). Cloned pets turning ten is our generation’s Bob Dylan turning seventy. Via the Houston Chronicle:

Almost 10 years later CC, aka Copy Cat, is still in the College Station area. She has a mate, Smokey, and they live with their three offspring in a cat mansion built by Dr. Duane C. Kraemer, an A&M researcher who helped bring CC into the world.

CC and her family seem like perfectly normal cats, which disappoints many guests hoping to see something more exotic, said Kraemer’s wife, Shirley, the head cat wrangler.

A&M’s cat-cloning operation was an offshoot of the Missyplicity Project to clone a dog named Missy with funding help from a company that wanted to market pet cloning.

Cloned Cow Milk and Meat Approved For Sale In U.K.

cowThe British equivalent of the FDA just announced that milk and beef from cloned cows is safe for consumption and may be sold without being labelled as such. The dairy and meat of the future has finally arrived…grab yourself a steaming hot cloneburger. The Telegraph reports:

The food safety watchdog said produce from the descendents of cloned pigs and cows is safe to eat and should not have to undergo any extra checks compared with other animals before going on sale.

Ministers are expected to rubber stamp the new guidelines, clearing the final hurdle for the meat and milk of cloned animals to be sold freely in Britain.

The FSA published new advice yesterday which stipulated that farmers must seek a license before selling meat or milk from cloned animals, but not their offspring.

The new guidance was prompted by a scare in the summer when it emerged that meat from the offspring of a cloned cow had been sold unwittingly in butchers’ shops without a license being obtained.

Should We Clone Neanderthals?

Reconstruction of Neanderthal man. Hermann Schaaffhausen (1888).

Reconstruction of Neanderthal man. Hermann Schaaffhausen (1888).

From the recent March/April issue of Archaeology. Zach Zorich writes:

If Neanderthals ever walk the earth again, the primordial ooze from which they will rise is an emulsion of oil, water, and DNA capture beads engineered in the laboratory of 454 Life Sciences in Branford, Connecticut. Over the past 4 years those beads have been gathering tiny fragments of DNA from samples of dissolved organic materials, including pieces of Neanderthal bone. Genetic sequences have given paleoanthropologists a new line of evidence for testing ideas about the biology of our closest extinct relative.

The first studies of Neanderthal DNA focused on the genetic sequences of mitochondria, the microscopic organelles that convert food to energy within cells. In 2005, however, 454 began a collaborative project with the Max Planck Institute in Leipzig, Germany, to sequence the full genetic code of a Neanderthal woman who died in Croatia’s Vindija cave 30,000 years ago.
