"In the winter of 2014, students at Iowa State University received emails asking them to volunteer for an experiment. Researchers were looking for women who would eat bananas that had been genetically engineered to produce extra carotenes, the yellow-orange nutrients that take their name from carrots. Our bodies use alpha and beta carotenes to make retinol, better known as vitamin A, and the experiment was testing how much of the carotenes in the bananas would transform to vitamin A. The researchers were part of an international team trying to end vitamin A deficiency. The emails reached the volunteers they needed to begin the experiment, but they also reached protesters. “As a student in the sustainability program, I immediately started asking questions,” said Iowa State postdoc Rivka Fidel. “Is this proven safe? Have they considered the broader cultural and economic issues?” ... Fidel told me she and her friends had found it nearly impossible to extract information from researchers, or from the Gates Foundation, which is providing funding for this project. Too often conversations about these kinds of issues simply reverberate within their respective echo chambers. So to bridge the gap I took the gist of the students’ questions to people at the Gates Foundation, scientists working on the banana, and the one person who may have done the most to fight vitamin A deficiency — an ophthalmologist who has no interest in either promoting or bashing GMOs."

New GM technique injects mosquitoes with a gene that results in mostly male offspring, eventually leading to a population crash. Previous efforts to tackle the disease, that kills more than 1 million people each year – most of whom are African children – have included bed nets to protect people and insecticides to kill the mosquito species most responsible for the transmission of malaria (Anopheles gambiae). The new technique by a team at Imperial College London involves injecting mosquitoes with a gene that causes the vast majority of their offspring to be male, leading to an eventual dramatic decline in population within six generations as females disappear. “You have a short-term benefit because males don’t bite humans [and transmit malaria],” Andrea Crisanti, one of the authors of the new research, which was published in the journal Nature Communications on Tuesday, told the Guardian. “But in the long term you will eventually eradicate or substantially reduce mosquitoes. This could make a substantial contribution to eradicating malaria, combined with other tools such as insecticides.”
These new mosquitoes are now set to be used in Brazil, having been approved for use by the Brazilian government with a factory for their production now opened.[more inside]
Glowing green pigs. Scientists from Taiwan have successfully created a bioluminescent pigs with genes from a jellyfish.
In lieu of today's posts on GM foods and meat, Trans Ova Genetics is pharming cows in hopes of creating one capable of adminstering human antibodies.
Today the British government released a major report on the safety of genetically modified foods. According to New Scientist, "existing genetically modified crops and foods pose a 'very low' risk to human health and are 'very unlikely' to rampage through the British countryside", but others disagree.
The genetically modified cat is out of the proverbial bag. New study finds traces of GM corn DNA in wild maize fields, over 60 miles away from the closest possible source. Are GM crops still the great idea that Monsanto thought they were? [via the pocket]
OK, cue the first GM babies. This time the men in white coats have crossed the line.
