the JOHN LAUDUN experiment

The title about says it all. The article that does the analysis is here and is published by the International Journal of Biological Sciences. The abstract states:

We present for the first time a comparative analysis of blood and organ system data from trials with rats fed three main commercialized genetically modified (GM) maize (NK 603, MON 810, MON 863), which are present in food and feed in the world. NK 603 has been modified to be tolerant to the broad spectrum herbicide Roundup and thus contains residues of this formulation. MON 810 and MON 863 are engineered to synthesize two different Bt toxins used as insecticides. Approximately 60 different biochemical parameters were classified per organ and measured in serum and urine after 5 and 14 weeks of feeding. GM maize-fed rats were compared first to their respective isogenic or parental non-GM equivalent control groups. This was followed by comparison to six reference groups, which had consumed various other non-GM maize varieties. We applied nonparametric methods, including multiple pairwise comparisons with a False Discovery Rate approach. Principal Component Analysis allowed the investigation of scattering of different factors (sex, weeks of feeding, diet, dose and group). Our analysis clearly reveals for the 3 GMOs new side effects linked with GM maize consumption, which were sex- and often dose-dependent. Effects were mostly associated with the kidney and liver, the dietary detoxifying organs, although different between the 3 GMOs. Other effects were also noticed in the heart, adrenal glands, spleen and haematopoietic system. We conclude that these data highlight signs of hepatorenal toxicity, possibly due to the new pesticides specific to each GM corn. In addition, unintended direct or indirect metabolic consequences of the genetic modification cannot be excluded.

I read the article to the best of my abilities, but that doesn’t mean I am in a position to evaluate it. GM crops seems like such a terrific thing, but it may be that the technology has outpaced our ability to understand its impact on complex ecosystems, including ourselves.

The universe is sometimes an amazing thing. After yesterday’s correspondence with my dad, the Digital Humanities list brought me a link to this YouTube clip from Jacob Bronowski’s The Ascent of Man:

An amazing talk by a molecular biologist:

From the Wired article:

NASA is taking the rare step of reaching out to the public for help. The space agency is looking for the best way to analyze and electronically catalog a precious collection of notes that chronicle the early history of the human space flight program.

“We’re looking for creative ways to get it out to the public,” said project manager Jason Crusan. “We don’t always do the best with putting out large sets of data like this.”

The notes are those of rocket scientist Wernher von Braun, the fist director of NASA’s Marshall Spaceflight Center in Huntsville, Alabama and are typed with copious hand written notes in the margin. According to the official request for information, NASA needs ideas on what format to use, how to index the notes and how to create a useful database.
