Three years after I wrote Genetic Roulette: The Documented Health Risks of Genetically Engineered Foods, pro-GM scientists have finally taken me up on my challenge to supply evidence that counters any of the 65 risks highlighted in the book. So, it will be a great pleasure for me to respond to the 65 arguments recently posted on a new attack-Jeffrey website. Their effort offers a priceless opportunity to not only revisit each health risk, but also to show more precisely where and how the biotech industry comes up short in its defense. Be sure to subscribe to my Huffington Post blog to catch the fun. In my initial challenge to the GMO industry, I sought rigorous, independent scientific data that would enrich the global discussion and better characterize GMO risks. But the posts written by biotech apologists Bruce Chassy and David Tribe demonstrate without doubt how flimsy and unsupported the industry's claim is that GMOs are safe...

The National Research Council has released a report essentially crowing about the benefits of genetically modified seeds (the “Roundup Ready” variety), albeit with a caveat warning against overuse. Personally, I’m extremely skeptical and it makes me question the integrity of the report and the institution publishing it. Your thoughts in the comments section please. Here’s the press release, in full:

Genetically Engineered Crops Benefit Many Farmers,
But The Technology Needs Proper Management to Remain Effective
WASHINGTON — Many U.S. farmers who grow genetically engineered (GE) crops are realizing substantial economic and environmental benefits — such as lower production costs, fewer pest problems, reduced use of pesticides, and better yields — compared with conventional crops, says a new report from the National Research Council. However, GE crops resistant to the herbicide glyphosate — a main component in Roundup and other commercial weed killers — could develop more weed problems as weeds evolve their own resistance to glyphosate.
Thanks scientists for taking mosquitoes from an “annoying” level to now a plot line for a super-villain. Martin Enserink writes on ScienceNOW:

Here’s a study to file under “unworkable but very cool.” A group of Japanese researchers has developed a mosquito that spreads vaccine instead of disease. Even the researchers admit, however, that regulatory and ethical problems will prevent the critters from ever taking wing — at least for the delivery of human vaccines.
Scientists have dreamed up various ways to tinker with insects’ DNA to fight disease. One option is to create strains of mosquitoes that are resistant to infections with parasites or viruses, or that are unable to pass the pathogens on to humans. These would somehow have to replace the natural, disease-bearing mosquitoes, which is a tall order. Another strategy closer to becoming reality is to release transgenic mosquitoes that, when they mate with wild-type counterparts, don’t produce viable offspring.

Medical experts will be watching closely Monday when a scientist who says she has been intermittently paralyzed by a virus designed at the Pfizer laboratory where she worked in Groton opens a much anticipated trial that could raise questions about safety practices in the dynamic field of genetic engineering.
Organizations involved in workplace safety and responsible genetic research already have seized on the federal lawsuit by molecular biologist Becky McClain as an example of what they claim is evidence that risks caused by cutting-edge genetic manipulation have outstripped more slowly evolving government regulation of laboratories.
McClain, of Deep River, suspects she was inadvertently exposed, through work by a former Pfizer colleague in 2002 or 2003, to an engineered form of the lentivirus, a virus similar to the one that can lead to acquired immune deficiency syndrome, or AIDS. Medical experts working for McClain believe the virus has affected the way her body channels potassium, leading to a condition that causes complete paralysis as many as 12 times a month.
Here is another chapter from Russ Kick's classic bite-size Disinformation book 50 Things You're Not Supposed to Know, published in 2003.The earthshaking news appeared in the medical journal Human Reproduction under the impenetrable headline: “Mitochondria in Human Offspring Derived From Ooplasmic Transplantation.” The media put the story in heavy rotation for one day, then forgot about it. We all forgot about it. But the fact remains that the world is now populated by dozens of children who were genetically engineered. It still sounds like science fiction, yet it’s true.

BANGALORE [India]: Criticising Genetically Modified (GM) products could land you in jail — if the draconian draft Biotechnology Regulatory Authority Bill (BRAB) of 2009, which will be tabled in the current session of the parliament by the UPA government, is passed.
In an unprecedented muzzle on the right to freedom of speech of the citizen, Chapter 13 section 63 of the draft bill says, “Whoever, without any evidence or scientific record misleads the public about the safety of the organisms and products…shall be punished with imprisonment for a term that shall not be less than six months but which may extend to one year and with fine which may extend to two lakh rupees or with both.” The BRAI Bill drafted by the department of bio-technology under the Ministry of Science and Technology comes on the heels of a moratorium on Bt Brinjal announced by the Environment Minister Jairam Ramesh.

…The first thing to understand about the new science of synthetic biology is that it’s not really a new science; it’s a brazen call to conduct an existing one much more ambitiously. For almost 40 years, genetic engineers have been decoding DNA and transplanting individual genes from one organism into another. (One company, for example, famously experimented with putting a gene from an arctic flounder into tomatoes to make a variety of frost-resistant tomatoes.) But synthetic biologists want to break out of this cut-and-paste paradigm altogether. They want to write brand-new genetic code, pulling together specific genes or portions of genes plucked from a wide range of organisms — or even constructed from scratch in a lab — and methodically lacing them into a single set of genetic instructions.

A new way of using the genetic code has been created, allowing proteins to be made with properties that have never been seen in the natural world. The breakthrough could eventually lead to the creation of new or “improved” life forms incorporating these new materials into their tissue.
In all existing life forms, the four “letters” of the genetic code, called nucleotides, are read in triplets, so that every three nucleotides encode a single amino acid.
Not any more. Jason Chin at the University of Cambridge and his colleagues have now redesigned the cell’s machinery so that it reads the genetic code in quadruplets.
In the genetic code that life has used up to now, there are 64 possible triplet combinations of the four nucleotide letters; these genetic “words” are called codons. Each codon either codes for an amino acid or tells the cell to stop making a protein chain.
Caltech scientists have already engineered stem cells into B cells that produce HIV-fighting antibodies – and an NIH researcher engineered T cells that recognize tumors which has already had promising clinical trials again skin cancer. Now a microbiology professor now asks: could we just genetically engineer all the antibodies we need?
Describing “Immunity on demand, he writes “…there’s a good chance this system, or something like it, will actually be in place within decades!”
“Our best hope may be to cut out the middleman. Rather than merely hoping that the vaccine will indirectly lead to the antibody an individual needs, imagine if we could genetically engineer these antibodies and make them available as needed?”
Can ethics be quantified? Or, better yet, can a lack of ethics be quantified? This week, the Swiss research firm Covalence released its annual ranking of the overall ethical performance of multinational corporations. The idea behind the Covalence research is that there's value — both for companies and consumers — in measuring corporations against an ethical standard. (We're hoping this idea also applies to Wall Street firms.)
Monsanto, the Missouri-based agriculture giant, ranked dead last in the Covalence ethical index. The company, which leads the world in the production of genetically-engineered seed, has been subject to myriad criticisms. Among them: the company is accused of frequently and unfairly suing small farmers for patent infringement.
