"The biochemistry information in the crop circle is the same as the Arecibo message, although the DNA seems to have an extra strand and a somewhat different number of nucleotides. It has also been noted that silicon is now indicated as part of the biological construction kit, although this element, while popular in science fiction, is rather poor at making the complex molecules required for life....

There is something about Silicon that is being conveyed in this message. It is not clear at all that Silicon must play a role in the DNA. But it is clear that it plays some important role. Dr. William Levengood, who has pioneered the biochemical assessment techniques that differentiate real crop formations from hoaxes, has found anomalous deposits of Silicon, silicone, and silicates in real crop formations. In one such formation, a layer of extremely pure,
micro-crystalline white silicon was found in an 8"-wide layer 4" under all the affected plants, with no visible soil disturbance to show how the presumed hoaxers put it there. The Silicon was of a purity and crystalline structure that was never seen before. Furthermore, plants that grew in soil containing this white powdery Silicon displayed a 300% to 400% growth in biomass, compared to control plants. The seeds taken from plants that grew in the real formations looked fine, but showed a 40% decrease in seed weight and were dry inside. But, when planted, they germinated and grew tremendously fast, with a deep, lush green color and robust health, compared to control plants.

Mineralogist Sampath Iyengar, a 30-year specialist in clay mineralogy at California's Technology of Materials Laboratory, used X-ray diffraction and a scanning electron microscope to examine specific heat-sensitive clay minerals such as Silicon from crop-formation soils. He discovered a 95%-statistically significant increase in the degree of crystallinity in the circle soils. "I was shocked," he said. "These changes are normally found in sediments buried for thousands and thousands of years under rocks, affected by heat and pressure, and not in surface soils."

The best-known expert in the world on X-ray diffraction analysis of clay minerals is Dr. Robert C. Reynolds Jr., former president of the Clay Minerals Society and emeritus professor of geology and mineralogy at Dartmouth College. He concluded that the intense heat required for the observed changes in crystallinity "would have incinerated any plant material present. In short, I believe that our present knowledge provides no explanation." In fact, a recent study published by a team of scientists and funded by Laurance Rockefeller concludes "it is possible that we are observing the effects of a new or as yet undiscovered energy source."

Blanche McLanahan, whose late husband was researching Silicon biology when he died in 1994, believes that the Visitors may be telling us how to absorb energy from light. In human blood the heme, or iron-based porphyrin, is surrounded by four Nitrogen atoms. "If Silicon replaces the Iron atom," she reports, "it prevents the ferric domain in the Iron atom's m-shell from storing energy. The Silicon would allow our bodies to use the energy of the sun through the principles of photosynthesis, absorbing energy through the cutaneous membrane directly into the blood through the Chloride shift in the capillaries."
