Scientists Recover Wooly Mammoth Blood
westtxfun writes
"'Russian scientists claimed Wednesday they have discovered blood in the carcass of a woolly mammoth, adding that the rare find could boost their chances of cloning the prehistoric animal.' As scientists unearthed the recent find, very dark blood flowed out from beneath the mammoth, and the muscle tissue was red. This is the best-preserved specimen found so far and they are hopeful they can recover DNA and clone a mammoth. Semyon Grigoriev, one of the researchers, said, 'The approximate age of this animal is about 10,000 years old. It has been preserved thanks to the special conditions, due to the fact that it did not defrost and then freeze again. We suppose that the mammoth fell into water or got bogged down in a swamp, could not free herself and died. Due to this fact the lower part of the body, including the lower jaw, and tongue tissue, was preserved very well. The upper torso and two legs, which were in the soil, were gnawed by prehistoric and modern predators and almost did not survive.'"
Tiger blood is just so passe now.
Wooly mammoth vacuum cleaners, wooly mammoth shower heads, the possibilities for the modern stone age family are endless...
There is obviously some money for the research, and a zoo would bring in enough revenue to help offset research costs, but how much do you think someone might bid to be the first person in 10,000 years to hunt and kill a woolly mammoth? $20M? $50M? That would go a long way in funding further research. Even better: to do so with stone age weapons.
The contract could stipulate that the researchers still own the carcass, and therefore could profit from auctioning the hide or the ivory. Of course, it would be a long time after cloning until such an endeavor was even worthwhile.
Being a pretentious douche, however, is universal (ok, maybe not among those aboriginal groups).
A custom that is dying a bit on account of the advent better small, local, and craft beers. Now if the smaller breweries can only avoid fratricide. But, seriously, would you want to drink American mega-brews at a temperature you could taste them?
Carpaccio, mett, kifto, sakuraniku (or any sashimi like basashi with meat), and dare I look at Wikipedia to find more? In any case, I wouldn't suggest destroying the flavor of this carefully aged meat with the application of heat. Besides, think of all the jokes a person could make with this coming from a steppe country. Mammoth tartare, etc... actually, there's no etc. That's all I've got. And given that preparation isn't actually mongol, meh.
No, not really. Steak Tartar -for example- originated in Europe. France to be more specific. https://en.wikipedia.org/wiki/Steak_tartare Check out the History and Regional variations sections. Not too mention the Swedish 'Rabiff' version which usually resembles the Danish version pretty closely.
Eating meat nearly raw is mostly an American custom (ok, and some aboriginal groups').
Bullshit.
Citation: Sushi, Sashimi, Carpaccio, Tartare, etc.
The only raw meat eaten in the US comes from dishes which are popular in other countries, it's not our custom.
As for the beer, we drink it cold because refrigeration became commonplace for even the poorest families over here. Back in Europe refrigeration is much less common and wasn't adopted as early or as widely, so people are still used to drinking piss-warm beer.
What kind of 2-bit "internet hero" are you to think that, because your managed managed to reach nature.com, you now know more about DNA and cloning than the chief scientist Semyon Grigoryev, professor at North-East Federal University?
The kind that can do math? From that very article:
The team predicts that even in a bone at an ideal preservation temperature of 5 C, effectively every bond would be destroyed after a maximum of 6.8 million years. The DNA would cease to be readable much earlier — perhaps after roughly 1.5 million years, when the remaining strands would be too short to give meaningful information.
“This confirms the widely held suspicion that claims of DNA from dinosaurs and ancient insects trapped in amber are incorrect,” says Simon Ho, a computational evolutionary biologist at the University of Sydney in Australia. However, although 6.8 million years is nowhere near the age of a dinosaur bone — which would be at least 65 million years old — “We might be able to break the record for the oldest authentic DNA sequence, which currently stands at about half a million years,” says Ho.
Emphasis mine.
So 10K years -- enough material and it should certainly be possible.
You don't need a full piece of DNA, just lots of small pieces you can combine into a full one. While I appreciate that posting on /. gives you the ability to second guess any amount of considered research and scientific understanding, from time to time reality does kick in.
The half life of all DNA is 521 years.
Did you even READ that article?
"After cell death, enzymes start to break down the bonds between the nucleotides that form the backbone of DNA, and micro-organisms speed the decay. In the long run, however, reactions with water are thought to be responsible for most bond degradation. Groundwater is almost ubiquitous, so DNA in buried bone samples should, in theory, degrade at a set rate."
So, that 'half life' is for buried bones in fairly specific situations. It doesn't apply everywhere.
Best part of all, is that story you linked to has its own related stories, and the first link is another story where they recovered DNA from 19,000 year old eggshells.
The second link is a story about sequencing the DNA from 100,000+ year old polar bears. Where the 'cold DRY' environment allows DNA to be preserved.
"I do not think that word means what you think it means."
Eating meat nearly raw is mostly an American custom (ok, and some aboriginal groups'). So is drinking beer so cold you can't feel any taste.
Actually what you call rare in the US, is called well done in continental Europe.
What the fuck? Stop making rules for drinking beer... or anything else for that matter. It tastes best however the fuck I want to drink it. My aunt drinks hot tap water. Fucking weird shit, but I'm not pretentious enough to tell her how she's "doing it wrong"
Maybe in this case we can use an elephant? The last thing I want is an elephant sized creature that can grab things at a distance with its tongue at blindingly fast speed. Not to mention could you imagine how high/far it could jump? It would be terrifying.

Don't let facts get in the way of a pretentious rant.
Americans don't realize that if they raised their animals well that raw meat would be pretty safe.
Oh, I think we realize that. What we also realize is that if we serve undercooked meat to our customers and they happen to get sick from that or anything else, they will sue us and win. Better to be safe than sorry, even if it destroys the taste. This is why we can't have nice things.
