I thought this might interest you all. The following are extracts from another Forum discussion.
This may sound silly at first but research shows that all living cells has a circaseptan rhythm. (meaning a 7 day rhythm).
SABBATH KEEPING BEES
I first heard about it on a NEWSTART health Program Lecture. Anyway, do you know Dr. Sang Lee? He goes to Brazil often as he has good friends there. He talks about these bees in his health lectures. Apparently these bees live in very remote areas, never touched by man or any civilization living even near to these places. So it's almost like it is preserved and Man's influenced did not penetrate there.
These bees living there are stingless. There are Bee keepers who lives in little huts alone with their family who keeps the bees in the forest in stumps where they close both ends with clay. Anyway, those families who have been keeping these bees for years and some for generation, knows very well that they don't work on the 7th Day Sabbath. The bees stay in the hives and rest.
When Dr. Lee heard of that, he had to go and see it for himself it it were true. Sure enought, on Sabbath there were no activities and the bees didn't go out of the hive to gather nectar. Dr. Lee ask to open one of the hives for he wanted to see if the Bees were really in there. The Bee Keeper cracked open one and sure enough the Bees were all in there.
Then Dr. Lee stayed over and wanted to see if the Bees would work on Sunday. Sure enough, all the hives were busy going in and out resuming their usual BEEing activities.
---- here's a description of circaseptan rhythm ---------
The most intriguing of all biological rhythms are those set to a clock of about seven days. In his chapter "The Importance of Time," Jeremy Campbell reports: "These circaseptan, or about weekly, rhythms are one of the major surprises turned up by modern chronobiology. Fifteen years ago, few scientists would have expected that seven-day biological cycles would prove to be so widespread and so long established in the living world. They are of very ancient origin, appearing in primitive one-celled organisms, and are thought to be present even in bacteria, the simplest form of life now existing." [Jeremy Campbell, Winston Churchill's Afternoon Nap, (New York: Simon and Schuster, 1986), p. 75]
One of Franz Halberg's amazing discoveries is that of an innate rhythm -- about seven days -- occurring in a giant alga some five million years old on the evolutionary time line. Because this microscopic cell resembles a graceful champagne glass, the alga (plant) is popularly known as mermaid's wineglass (Acetabularia mediterranea). When this "primitive" alga is subjected to artificial schedules of alternating light and dark spans of varying length over many days, this single intact cell is somehow able to translate all that manipulation of light and darkness into the measurement of a seven-day week!
As Campbell says, this inherent rhythm has to do with the internal logic of the body, not with the external logic of the world. Many more examples could be given. Involved experimentation with rats, face flies, plants and other life have revealed circaseptan rhythms similar to that of the mermaid's wineglass. [Franz Halberg, "Quo Vadis Basic and Clinical Chronobiology: Promise for Health Maintenance," American Journal of Anatomy 168:543-594 (1983), pp. 569-570; Campbell, pp. 75-76.]
Here's more about it :
But was it culture and religion alone that eventually moved earth's six billion people to now harmonize in a universal seven-day rhythm [the week]? The new and respected science of chronobiology (the study of how living things handle time) says no. Its discovery of circaseptan ("about seven") rhythms in human and other life forms points toward a biological explanation for the mystery of the week. In his study into the human nature of time, Jeremy Campbell states: "Inner time structure, in certain of its manifestations, seems to determine outer time structure, rather than the other way round. Rhythms of about seven days arose in living creatures millions of years before the calendar week was invented, and may conceivably be the reason why it was invented." [Jeremy Campbell, Winston Churchill's Afternoon Nap, (New York: Simon and Schuster, 1986). p. 83]
In addition to being the key coordinating rhythm for the rest of the body's many rhythmic interactions, a seven-day cycle has been found in fluctuations of blood pressure, acid content in blood, red blood cells, heartbeat, oral temperature, female breast temperature, urine chemistry and volume, the ratio between two important neurotransmitters, norepinephrine and epinephrine, and the rise and fall of several body chemicals such as the stress coping hormone, cortisol. "In fact," Perry and Dawson note, "weekly rhythms appear easiest to detect when the body is under stress, such as when it is defending itself against a virus, bacterium, or other harmful intruder. For example, cold symptoms (which are really signs of the body defending itself against the cold virus) last about a week. Chickenpox symptoms (a high fever and small red spots) usually appear almost exactly two weeks after exposure to the illness.:" [Susan Perry and Jim Davson, The Secrets Our Body Clocks Reveal, (New York: Rawson Associates, 1988) p. 22.]
Doctors have long observed that response to malaria infection and pneumonia crisis peaked at seven days. Organ transplants face similar crises as the body's immune system attack the foreign organ. Campbell explains: "When a human patient receives a kidney transplant, there is a rhythm of about seven days, a predictable rise and fall in the probability that the body's immune system will reject the new kidney. A major peak of rejection occurs seven days after the operation, and when a serum is given to suppress the immune reaction, a series of peaks occurs, with increasing risk of rejection, at one week, two weeks, three weeks and at four weeks, the time of the highest of all." [Campbell, p 76.]
Not only did the Designer/Creator leave his finger prints on everything he made, he left his calling card bonded to living cells telling us when he made life: in a seven-day creation week. That's when he wound up the clock of life and set it ticking in each of its forms to a rhythm of sevens. He gave life the frequency of seven. It's the beat of creation, a harmonic that points directly to the life-starter, life-giver himself!
