A contender for the elusive fountain of youth: an enzyme found in humans appears to lengthen the life of mice. Researchers hoping to slow the march of age were dealt a blow in 2010, when signs that an enzyme called sirtuin 2 extended the life of worms were shown to be false due to flawed experimental design. Mammals have seven types of sirtuin, so Haim Cohen and Yariv Kanfi at Bar-Ilan University in Ramat Gan, Israel, turned to sirtuin 6 instead. They compared mice genetically engineered to have increased levels of SIRT6 with normal mice, engineering the mice in two different ways to control for genetic influences. Male mice from both strains lived 15 per cent longer than normal mice or females. Older modified male mice metabolised sugar faster than normal mice and females, suggesting that SIRT6 might extend life by protecting against metabolic disorders such as diabetes ...

We regret to inform our readers that this story is based on a Daily Mail article that we have now been informed is from 2003, not 2012. In their own search engine, Daily Mail mistakenly listed their own story as being published on February 3, 2012…
Oh well – let’s pressure Monsanto to get out of the UK anyway!
Mike Adams reports for Natural News:

A massive victory against Monsanto and genetically engineered seeds has been achieved in the United Kingdom today. Monsanto has announced a total withdrawal from the UK, shuttering its Cambridge-based wheat production operation. UK newspaper Daily Mail was instrumental in promoting opposition against Monsanto through its “Frankenstein Foods” educational campaign.
The paper is now reporting that Monsanto plans to sell off GMO crop-breeding centers in France, Germany and the Czech Republic. Daily Mail reported, “…the company has given up hopes of introducing GM crops to Europe.” (Are you grinning as wide as I am right now?)
The UK government, it turns out, was on the verge of announcing a finding that genetically engineered crops would “pollute the countryside for generations.” Gee, ya think?
Gordon Davidson writes in the Scottish Farmer:
France has held firm in its opposition to Monsanto’s genetically modified MON 810 maize [trade name: YieldGard] – and the agri-chemical multinational has admitted defeat.
Monsanto had been putting legal pressure on the French government to lift its 2008 cultivation ban on MON 810, firstly with a successful appeal to the European Court of Justice, then with a follow-up case heard in France’s own highest court, the Council of State.But despite both these institutions ruling that the ban was “insufficiently justified in law”, the French Government, backed by President Sarkozy, has insisted that it will still not allow cultivation of the biotech maize.
Now Monsanto has announced that it would not be selling seeds for MON810 in France this year.
France’s stand – and Monsanto’s capitulation – has been warmly welcomed by anti-GM lobbyists GM Freeze, whose campaign director Pete Riley said: “The decision by Monsanto not to market MON810 seeds in France in 2012 is yet another sign that Monsanto has failed to convince the public or policy makers that there is any benefit to growing to growing GM crops…

In a study released by the International Journal of Biological Sciences, analyzing the effects of genetically modified foods on mammalian health, researchers found that agricultural giant Monsanto’s GM corn is linked to organ damage in rats.
According to the study, which was summarized by Rady Ananda at Food Freedom, “Three varieties of Monsanto’s GM corn – Mon 863, insecticide-producing Mon 810, and Roundup® herbicide-absorbing NK 603 – were approved for consumption by US, European and several other national food safety authorities.”
Monsanto gathered its own crude statistical data after conducting a 90-day study, even though chronic problems can rarely be found after 90 days, and concluded that the corn was safe for consumption. The stamp of approval may have been premature, however.
A Dutch researcher has created a virus with the potential to kill half of the planet’s population. Now, researchers and experts in bioterrorism debate whether it is a good idea to publish the virus creation ”recipe”. However, several voices argue that such research should have not happened in the first place. The virus is a strain of avian influenza H5N1 genetically modified to be extremely contagious. It was created by researcher Ron Fouchier of the Erasmus Medical Center Rotterdam, Netherlands. The work was first presented at a conference dedicated to influenza, that took place in September in Malta. Avian influenza emerged in Asia about 10 years ago. Since then there were fewer than 600 infection cases reported in humans. On the other hand, Fouchier’s genetically modified strain is extremely contagious and dangerous, killing about 50% of infected patients. The former strain did not represent a global threat, as transmission from human to human is rare. Or, at least, it was before Fouchier genetically modified it.

A new breed of genetically modified mosquitoes carries a gene that cripples its own offspring. They could crush native mosquito populations and block the spread of disease. And they are already in the air — though that’s been a secret.
Outside Tapachula, Chiapas, Mexico — 10 miles from Guatemala. To reach the cages, we follow the main highway out of town, driving past soy, cocoa, banana and lustrous dark-green mango plantations thriving in the rich volcanic soil. Past the tiny village of Rio Florido the road degenerates into an undulating dirt tract. We bump along on waves of baked mud until we reach a security checkpoint, guard at the ready. A sign posted on the barbed wire–enclosed compound pictures a mosquito flanked by a man and woman: Estos mosquitos genéticamente modificados requieren un manejo especial, it reads. We play by the rules.

You have to wonder what’s going on in the DNA of Harvard genetics professor George Church.
What extra bit of code does he have that the rest of us don’t? If genes tell the story of a person’s life, then some altered sequence of ‘A’s, ‘C’s, ‘G’s and ‘T’s must be at play, because his brain works like almost no one else’s.
About 30 years ago, Prof Church was one of a handful of people who dreamed up the idea of sequencing the entire human genome – every letter in the code that separates us from fruit flies as well as our parents. His lab was the first to come up with a machine to break that code, and he’s been working to improve it ever since.
Agribusiness monster corporation Monsanto is in peril of creating a worse problem than it purports to solve with its genetically modified corn plants. Scott Kilman reports for the Wall Street Journal:

Widely grown corn plants that Monsanto Co. genetically modified to thwart a voracious bug are falling prey to that very pest in a few Iowa fields, the first time a major Midwest scourge has developed resistance to a genetically modified crop.
The discovery raises concerns that the way some farmers are using biotech crops could spawn superbugs.
Iowa State University entomologist Aaron Gassmann’s discovery that western corn rootworms in four northeast Iowa fields have evolved to resist the natural pesticide made by Monsanto’s corn plant could encourage some farmers to switch to insect-proof seeds sold by competitors of the St. Louis crop biotechnology giant, and to return to spraying harsher synthetic insecticides on their fields.
“These are isolated cases, and it isn’t clear how widespread the problem will become,” said Dr.
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.
The Institute of Science in Society‘s Dr. Mae-Wan Ho reports that a USDA senior scientist has sent an “emergency” warning to US Secretary of Agriculture Tom Vilsack regarding a new plant pathogen in Roundup Ready GM soybean and corn that may be responsible for high rates of infertility and spontaneous abortions in livestock:

An open letter appeared on the Farm and Ranch Freedom Alliance founded and run by Judith McGeary to save family farms in the US [1, 2]. The letter, written by Don Huber, professor emeritus at Purdue University, to Secretary of Agriculture Tom Vilsack, warns of a pathogen “new to science” discovered by “a team of senior plant and animal scientists”. Huber says it should be treated as an “emergency’’, as it could result in “a collapse of US soy and corn export markets and significant disruption of domestic food and feed supplies.”
The letter appeared to have been written before Vilsack announced his decision to authorize unrestricted commercial planting of GM alfalfa on 1 February, in the hope of convincing the Secretary of Agriculture to impose a moratorium instead on deregulation of Roundup Ready (RR) crops.
