DNA 2.0: A New Operating System for Life is Created

DNALinda Geddes writes in New Scientist:

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.

Can We Engineer Immunity on Demand?

Immune_responseCaltech 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?”… Read the rest

Monsanto: The #1 Most Unethical Company In The World

Grace Kiser writes on the Huffington Post:

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

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.

More Herbicide Use Reported On Genetically Modified Crops

By Julie Masis for the Christian Science Monitor:

A report has found that farmers are using more herbicides on genetically engineered soybeans, corn, and cotton because of resistant weeds.

A report has found that farmers are using more herbicides on genetically engineered soybeans, corn, and cotton because of resistant weeds.

A report released by the Organic Center found that the amount of herbicides used on genetically engineered crops has increased in the past 10 years, not decreased as might be expected. Since many genetically engineered crops were modified so that farmers could spray Roundup, or Glyphosate, to kill the weeds in their fields but not the crops themselves, the expectation was that less herbicide would be required. But the new report found that this is not what happened.

The authors of the report, entitled “Impacts of Genetically Engineered Crops on Pesticide Use,” used US Department of Agriculture data to look at America’s three largest genetically engineered crops – soybeans, corn, and cotton.

93% of Soybeans, 80% of Corn Grown from Genetically-Modified Monsanto Seeds

MonsantoRainPeter Whoriskey reports in the Washington Post:

For plants designed in a lab a little more than a decade ago, they’ve come a long way: Today, the vast majority of the nation’s two primary crops grow from seeds genetically altered according to Monsanto company patents.

Ninety-three percent of soybeans. Eighty percent of corn.

The seeds represent “probably the most revolutionary event in grain crops over the last 30 years,” said Geno Lowe, a Salisbury, Md., soybean farmer.

But for farmers such as Lowe, prices of the Monsanto-patented seeds have steadily increased, roughly doubling during the past decade, to about $50 for a 50-pound bag of soybean seed, according to seed dealers.

The revolution, and Monsanto’s dominant role in the nation’s agriculture, has not unfolded without complaint. Farmers have decried the price increases, and competitors say the company has ruthlessly stifled competition.

Now Monsanto — like IBM and Google — has drawn scrutiny from U.S.

Scientists Breed A Smarter Rat!

Scientists have engineered a more intelligent rat, with three times the memory length of today’s smartest rats!

Reseachers bred transgenic over-expression of the NR2B gene, which increased communication between the rat’s memory synapses. Activating a crucial brain receptor for just a fraction of a second longer produces a dramatic effect on memory – as proven by the rat’s longer memories of the path through a maze to a chocolate treat!… Read the rest
