About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.


Subscriptions

Subscriptions to the Science Frontiers newsletter are no longer available.

Compilations of back issues can be found in Science Frontiers: The Book, and original and more detailed reports in the The Sourcebook Project series of books.

Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Immune System As A Sensory Organ John Maddox, the editor of Nature, has written a remarkable editorial on psychoimmunology; that is, the science of the brain's effects on the body's immune system. It is basically a running commentary on new discoveries that are helping us to understand this poorly appreciated relationship. Maddox begins by mentioning the 20-plus-year collection compiled by Professor G.W . Brown, University of London, of life-events that affect the health of outwardly normal people. Typical life-events are the death of a spouse, imprisonment, personal bankruptcy, etc. Everyone seems to recognize ... - if only through anecdotes -- that mental states affect health, but how this brain-body link is maintained is hard to pin down. D. Maclean and S. Reichlin (Psychoneuroimmunology, 12: 475, 1981.) have reviewd some of the possible connections. One potential link is through the interaction of the hypothalamus on the pituitary. The pituitary is a source of materials that influence the immune system. Maddox lists several specific candidates, and then observes: "The more radical psychoimmunologists talk as if there is no state of mind which is not faithfully reflected by a state of the immune system." So far, not too radical! But then Maddox comes to an article by J.E . Blalock, University of Texas (Journal of Immunology, 132:1067 ...

... Science Frontiers ONLINE No. 15: Spring 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Evolutionary Struggle Within Ted Steele, an immunologist, has come up with experimental evidence showing in some cases that acquired immunity may be transmitted to progeny. When Steele's research was announced, many scientists and science writers rushed to the defense of Darwinism. They pointed out with unseeming vigor that a revival of dread Lamarckism or the Inheritance of Acquired Characters was not indicated. It is true that Steele has proposed a Darwinian interpretation of his findings, but his theory adds a startling new dimension to the development of life. In essence, Steele asserts that an organism's immunological system is really the evolutionary scenario in miniature and compressed in time. ... body's immuno-logical system is trying to cope with up to 10 million defensive cells. The only defensive cells that survive and multiply are those that happen to encounter an invader that they can lock onto and destroy. The "fittest" defensive cells are those that have just the right characteristics to knock off invaders, and only they survive permanently in the body's defensive arsenal, giving it acquired immunity. The Lamarckian part of this story occurs when the RNA of the selected defensive cells gets passed on to the organism's progeny. (Tudge, Colin; "Lamarck Lives -- In the Immune System," New Scientist, 89:483, 1981.) Comment. The picture evolving here is one of a hierarchy of evolutionary struggles -- say, humans ...

... patient improves because he believes he is getting a helpful medicine, even though it is an inert substance. The reverse works, too, at least in experiments with mice. It seems that mice can be conditioned into believing that an ordinarily delectable substance (saccharin and water) gives them stomach pain, by simultaneously injecting them with a pain-producing chemical. Unexpectedly, this chemical also suppressed the immune system of the mice. The mice, of course, knew nothing about the effect on their immune system. Nevertheless, whenever they received saccharin after being conditioned, their immune system was suppressed even though the pain-producing chemical was not administered. While one can imagine the mice consciously associating saccharin and stomach pain, and their brains somehow sending signals that simulated pain, it seems inconceivable that ... mice knew anything about their immune system. We have always assumed that the placebo effect (and its reverse) worked because of the subjects' logical association of cause and effect, but evidently there is something else going on here! (Wingerson, Lois; "Training the Mind To Heal," Discover, 3:80, May 1982.) Comment. This all opens a rather large Pandora's Box, because it implies that seemingly innocent signals can trigger unrealized reactions. It's something like a post-hypnotic suggestion. Some cause -- not recognized as a cause -- results in an effect -- not consciously related to the real cause. We could all be puppets, not even recognizing the strings that control us!

The woman had an immune-system disorder that had damaged a small portion of her brain's temporal lobe. Her other mental faculties were intact. "The woman could name plants, foods, and inanimate objects and describe them without hesitation. The scientists were impressed that when shown a trellis, not exactly your everyday object, she could correctly name it and describe its cross-hatched geometry. "But when shown a squirrel or a dog ... she froze. She couldn't find the right name for either, nor could she describe their size or shape or furry coats. "Her deficit, involving only a tiny portion of her language skills, was amazingly narrow." (Bor, Jonathan; "The Woman Who Couldn't Describe Animals," Baltimore Sun, p. A1, September 7, 1992.) The implications of this strange case were described in Science News: "The peculiar inability of a 70-yearold woman to name animals has led scientists to propose that the brain harbors separate knowledge systems, one visual, the other verbal or language-based, for different categories of living and inanimate things, such as animals and household objects."

... too radical a concept. But a few scientists are beginning to chart the chemistry and information flow in the mind-body relationship. For example, the death of a spouse has long been associated with the increased mortality of the surviving spouse. Clinical studies of bereaved spouses reveal fewer circulating lymphocytes, which help the body fight disease, and significantly higher levels of cortisol, a substance that suppresses the immune system's response to disease. Although it is very early in the game, there are verifiable correlations between state-of-mind and body chemistry. Further, other researchers have found that there are sympathetic nerve terminals in such organs as the spleen and lymph nodes, both of which play important parts in defending the body. Imaging just might send the right signals through these terminals, ... depression might tend to shut the defense system down. (Hammer, Signe; "The Mind as Healer," Science Digest, 92:47, 1984.)

The mother thus becomes a blend of herself and her child (or, possibly, children) - a kind of chimera. The question is: Why doesn't the mother's immune system destroy these foreign cells? Some scientists speculate that these escaped and still-surviving cells may help explain why women are more susceptible than men to autoimmune diseases.

The embryo continued to develop but it was part all-mother and part mother-father! "Partial parthenogenesis" seems to be the proper term here.
