Scientists aim for lab-grown meat

Pork cuts could come fresh from the lab
An international research team has proposed new techniques that may lead to the mass production of meat reared not on the farm, but in the laboratory.

Developments in tissue engineering mean that cells taken from animals could be grown directly into meat in a laboratory, the researchers say.

Scientists believe the technology already exists to directly grow processed meat like a chicken nugget.

The technology could benefit both humans and the environment.

"With a single cell, you could theoretically produce the world's annual meat supply. And you could do it in a way that's better for the environment and human health.

"In the long term, this is a very feasible idea," said Jason Matheny of the University of Maryland, part of the team whose research has been published in the Tissue Engineering journal.

Growing the meat without the animal could reduce the need to keep millions of animals in cramped conditions and would lessen the damage caused by the meat production to the environment.

Laboratory-grown meat could also be healthier, proponents say.

Eating 'mush'

Tissue engineering techniques were first developed for medical use and small amounts of edible fish tissue have been grown in research conducted by Nasa.


Concerns have been raised about eating meat from cloned animals.
To industrialise the process, researchers suggest the cells could be grown on large sheets that would need to be stretched to provide the 'exercise' for the growing muscles.

"If you didn't stretch them, it would be like eating mush," said Mr Methany.

Whilst the technology to produce processed meat is here now, producing a steak or chicken breast is still quite a way off, the researchers say.

Questions

The new techniques could also provide a dilemma for vegetarians.

Some may feel able to eat meat that has been grown without an animal being harmed.

Others feel that question marks remain about the way the cells would be taken from animals.

"It won't appeal to someone who gave up meat because they think it's morally wrong to eat flesh or someone who doesn't want to eat anything unnatural," Kerry Bennett of the UK Vegetarian Society told the Guardian newspaper.

How regulators might react is also unclear.

The US Food and Drug Administration has asked companies not to market any products that involve cloned animals until their safety has been evaluated.

Let’s be clear. Dr. Walker lived to be a healthy 118. He didn’t suffer from cancer, diabetes, heart attacks, strokes or any other killer or degenerative disease. He didn’t have to be pushed around in a wheel chair in his later years. He worked in his garden all morning on the day that he died.

Oldest Woman Ever
The oldest fully authenticated age to which any human has ever lived is 122 years and 164 days, by Jeanne-Louise Calment. She was born in France on February 21, 1875, and died at a nursing home in Arles, southern France on August 4, 1997. President Jacques Chirac once said Jean Calment was a little bit like a grandmother to everyone in France. She was 14 when the Eiffel Tower was completed in 1889. She led an extremely active life, taking up fencing at 85 years old, and was still riding a bicycle at 100. She portrayed herself at the age of 114 in the film Vincent And Me, to become the oldest actress in film.

That's the point! You wouldn't want to live to that age if you were an unhealthy mess! But according to Dr. Walker, in his old age he felt like he was still 30. Here's a quote:
"I can truthfully say that I am never conscious of my age. Since I reached maturity, I have never been aware of being any older, and I can say, without equivocation or mental reservation, that I feel more alive, alert, and full of enthusiasm today than I did when I was 30 years old. I still feel my best years are ahead of me. I never think of birthdays, nor do I celebrate them. Today I can truthfully say that I am enjoying vibrant health, I don't mind telling people how old I am: I AM AGELESS!"

Darwin, are you sure the oldest person ever was 122? There's a women in my town who is well into her 100's (I want to think 110, but I'm not positive at the moment). And I've read in a book about a man meeting someone in Germany who was supposedly 143 years old (obviously his age couldn't be proven, so it might not necessarily be correct).

I'm not positive that Dr. Walker was 118 exactly. He was definitely well into his 100s without a doubt, but I don't think anyone knows EXACTLY how old, but I've read from many sources that he was 118 when he died.

I suspect that guy was more of an exception. Thankfully, there'd be a huge rise in BMX theft otherwise ; )

Considering Dr. Walker is far more than a food guru, but a completely unbiased SCIENTIST, who has no animal rights agenda, who spent over seventy years of his life researching the subject and conducting experiments, living to be 118 years old, I'd say that his information is SCIENTIFIC. I don't see how it could possibly be any more scientific.

eh? He’s saying atoms die again isn’t he?



No, he never said that. He said the "life-principle," or enzymes, die.

The importance of VITALITY in the atoms composing the amino acids can best be appreciated by realizing that within 6 minutes after life leaves the body all the atoms in the body cease to be live, organic atoms, and their function and activity consequently comes to a stop. So long as life is present in the body, the live atoms therein have the vital spark of life which enables them to carry on their work.
