Most of the evidence linking the patient's mood with recovery from illness is anecdotal -- little wonder since mood is hard-to-measure. Some statistical evidence has recently been accumulated by S.M . Levy and R. Herber-man of the National Cancer Institute; but the situation still seems complex at best. From a study of 75 women with breast cancer, there appears to be a significant and involved relationship between age, the body's immune function, and a psychological factor called "fatigue." One clear-cut finding was that young patients facing radiation therapy and also reporting high levels of psychological fatigue were the only patients in the surveyed group showing diminished activity by the body's natural killer cells. These killer cells com-prise an important part of the defense against cancer. This biological consequence of apathy is confirmed by an-other study showing that cancer patients with "psychological distress" had better chances of recovery than those who had no "fight."

The article at hand from Antiquity does not attempt to interpret the Bradshaw art. Instead, it discusses the social factors that mold the interpretation of the Wandjina and Bradshaw paintings. When Europeans first saw these paintings they were certain that their "advanced style" was far beyond the capabilities of the Aborigines (colonial prejudice). They must, therefore, be the work of "preAborigines." Today's Aborigines will have none of this condescension. They were the original settlers of Australia, and as such they have bona fide land and title claims. Any recognition of "pre-Aborigines" would undercut these claims.

Nematodes are about a millimeter long and very active, thrashing through the soil like fish through water. Their numbers are kept in check by a surprisingly sophisticated fungus which thrives on them. If nematodes are around (not otherwise), the fungus sets out two kinds of traps. The first is the sticky net made of threads sent out by the fungus. Any nematode that brushes against these sticky strands is held while the fungus rams special feeding pegs into it. The second kind of trap is even more marvelous. It is an array of rings, each consisting of three unique cells that are sensitive to touch. Attracted by alluring chemicals secreted by the fungus, the nematodes probe around the rings. In a tenth of a second after they are touched, the fungus rings contract around the interloping nematodes. Again the nematode is doomed as the terrible feeding pegs penetrate its body. Another chemical is then released by the fungus to keep other fungi away from its kill. (Simons, Paul; "The World of the Killer Fungi," New Scientist, 20, March 1, 1984.) Comment.

These tidal patterns are evident even when the trees are kept in darkness and at constant pressure and humidity. Even more surprising, chunks of tree stems that are sealed to prevent water from flowing in or out will still expand and contract according to the 24-hour, 49-minute lunar cycle as long as the cambium, the most active growing region, survives.

He notes that General Relativity predicts that a particle (or person) in free fall cannot distinguish this condition (weightlessness) from the situation in a hollow shell of matter, where the gravitational field is cancelled out. A person would feel weightless in both situations. But the strange part arises when one looks at the two situations from the perspective of quantum mechanics; that is, one puts gravity into Shroedinger's equation. Ahluwalia asserts that the particle's (or person's ) gravitational presence is smeared out, just like that of the electron outside the solenoid. In consequence, masses can "feel" their gravitational potential and will behave differently in free fall than when inside a hollow sphere, contrary to what Einstein maintained in his General Relativity.

For example, keas (New Zealand parrots) consider it their duty to pry out the rubber gaskets around automobile windshields with their powerful bills. A cassowary can be even more forceful. Recently, a motorist near Cairns, Australia, was forced to stop by a sixfoot cassowary standing in the middle of the road. He edged the car forward slowly, but the huge bird stood its ground. Then, he blew his horn. Bad move! The cassowary objected by kicking the auto, pushing the radiator into the fan, which cut a hole in it. (Anonymous; "Feedback," New Scientist, p. 104, June 13, 1998.)

Then along came chaos theory which implied that the flight of a butterfly in Brazil could, in principle, affect weather in Canada. In effect, a slight change in initial conditions could, in the fullness of time, have very large effects. Now, it is generally admitted that the solar system is chaotic after all. Each planet is subject to the tiny, butterfly-like gravitational tugs of the other planets, especially Jupiter. Given enough time, these gravitational nuances can result in the ejection of a planet from the solar system -- and may already have done so in the past! Mercury and Mars are the most vulnerable on a billion-year time scale. In the case of Mercury, its orbit will become more and more elliptical according to computer simulations. Eventually a close gravitational encounter with Venus is possible. This could send Mercury careening off into deep space. The probability of this happening is only 1 in a 1000 over 5 billion years, but it is not zero. Mars might likewise be ejected by a passing nudge from earth. However, this encounter could go the other way. Depending upon the celestial dynamics of the encounter, Mars might gravitationally fling earth out into the Galaxy, and our planet would truly become "Spaceship Earth."

Systems that are more complex will possess many different final states, all chaotic. Can nature really be fundamentally chaotic as well as qualitatively uncertain? J.C . Sommerer and E. Ott have mathematically examined a relatively simple system consisting of a single particle moving in a force field, experiencing friction, and being periodically jolted. Besides settling into chaotic motion, this particle may also be forced away to infinity -- two radically different final states. The analysis revealed that for any set of initial conditions leading to the first type of behavior, there was an infinite number of slightly different initial conditions that would lead to the second type of behavior. In other words, systems that we have long thought to be deterministic, like the motions of the planets, may be not only chaotic but indeterminate. Since Sommerer and ...

Since this cataclysm is predicted to occur on Jupiter's far side, the pyrotechnics will be largely hidden from our telescopes. Yet, if any of Jupiter's four large Galilean satellites are swinging behind Jupiter during the comet's impact, but still visible to us by virtue of their distances from Jupiter, we might see one or more of these moons suddenly brighten due to light reflected from the incineration below. This very well might happen, and something similar has happened before. On July 26, 1983, just 6 minutes after it emerged from behind Jupiter, the Galilean satellite, Io, suddenly brightened by 50% -- a "flash" that lasted 118 seconds. Now, Io is notoriously fickle brightness-wise. Its post-eclipse brightening has long puzzled astronomers, but this short, intense flash was even more anomalous than usual. H.B . Hammel and R.M .

But Wolf shows how spectral changes are "sort of coded into the light due to correlations in the source." Meanwhile, two of Wolf's colleagues have backed up his theory in the lab. The consequences of Wolf's work would in effect shrink the universe, because objects would not be as far away as we now calculate from their redshifts. The size of the universe might contract "by a factor of 100 or more," says Wolf.

Indeed, Continental Drift is taught as an unassailable hypothesis -- in essence, a "fact." It is, therefore, a tempting target for anomalists. Fortunately, there are some maverick geologists who are willing and able to draw up a list of arguments against the "fact" of Continental Drift. Australian P. James is one such brave soul. Here follows the abstract from one of his papers. "Anomalies in the three basic concepts of mobile plate tectonics -- sea-floor spreading, transform faults, subduction -- are analysed. The process is then extended to subsidiary aspects; sediments on a moving basement, continental evidence, mechanisms and measurements. In summation, the criticisms present a formidable and damaging document against the total framework of mobilism, both in its general concepts and it its detailed interpretations."

Of course, no one expects that all branches of mathematics will mirror physical reality; but BTT is definitely ultra-weird, so much so that we had to invent that adjective! Take, for example, this specific BTT result presented by B. Augenstein: "In particular, a solid sphere with unit radius can be cut into five pieces in such a way that two of the pieces can be reassembled into one solid sphere with unit radius, while the other three pieces are reassembled into a second solid sphere with unit radius. These are the minimum numbers of pieces required to do the trick, but it can be repeated indefinitely." Impossible, you say? Can one sphere fragment and be reconstituted as two solid spheres of the same size? Regardless of what the math says, it cannot happen in the real world!

Other animals may be automatons, but not us! D. Jones speculates in Nature that if consciousness is a definite, inheritable characteristic, it must have had survival value for it to have evolved. It then follows that consciousness must be en-coded somewhere in our genes. Only a single gene may be enough, for consciousness seems to be an uncomplicated phenomenon. Why? Because just a few simple molecules, such as those found in anesthetics, can disable it completely without affecting other bodily functions. Eventually, Jones continues, the gene (or small number of genes) responsible for consciousness will be identified. Then, we can determine for certain if any of the lower animals are also conscious. We think chimps and dolphins might be, but we're not really sure until we see if they have the necessary genes. In fact, the old-time behaviorists could be right, and all the other animals really are merely automatons. That would definitely make us "special"!

One amusing though tedious method would require throwing a short, straight twig onto parallel lines drawn in the beach sand. You will be able to compute pi from: pi = 2lN/dH, where l = the length of the twig, which must be less than d, separation of the parallel lines. N = the number of throws. H = the number of times the twig crosses one of the lines. One famous performance of this experiment was by M. Lazzarini in 1901. He reported that in 3408 throws he got 1808 intersections, leading to: pi = 3.1415929 Actually, the final digit should be a 6. Thus, Lazzarini measured pi to a few parts in 10 million. Recently, L. Badger, Weber State University, concluded that Lazzarini probably never actually performed his experiment. His results were just too good -- too fortuitous! If the number of hits had been 1807 or 1809, pi would have been wrong by 1 part in 2,000. As it turns out, a Chinese mathematician of the 5th Century pointed out that 355/113 = 3.1415929.

"The Vera Cruz stele has the same enumeration symbols used by the Mayas -- small circles and bars -- which enabled Mr. Winfield to identify two dates among the hieroglyphics: May 22, 143, and July 13, 156. "The remaining glyphs probably record events between those dates. Although there are 20 glyph types similar to the ones used by the Mayas, 100 more are new. The stone carries a total of 600 glyphs." Winfield hopes that the newly found stele will help explain what happened during the transition between Olmec and Maya cultures. He thinks it possible that the stele is the product of a previously unrecognized civilization. (Anonymous; "Inscribed Stone May Hold Secrets of Mexican Culture," Baltimore Sun, June 8, 1988.)

... are the ones that fertilize chosen females. Their mechanical devices range from scrapers that physically remove sperm deposited by competing males to plugs that block sperm access in subsequent matings. It is claimed that some male ejaculates introduce not only fertilizing sperm but also "kamikaze" sperm specially designed to hunt down and destroy competing sperm. Well, both sexes can play these games. Some females have ways to eject sperm from undesired males. For example, female feral fowl (hens gone wild!) prefer to mate with dominant males. Often, however, subdominant males force themselves on the females despite resistance and stress calls. The female response to such rapes is differential sperm ejection; that is, they immediately expel the unwanted ejaculate -- at least most of it -- raising the probability that they will be fertilized by the preferred dominant males. (Pizzeria, T., and Birkhead, T.R .; "Female Feral Fowl Eject Sperm of Sub-dominant Males," Nature, 405:787, 2000.) Comment. An interesting sort of sperm ejection occurs among Dunnocks, small brown birds common in English gardens. Alpha males try to prevent matings by lower-ranking males but are rarely successful. Most Dunnock matings are preceded by a ritual-like phenomenon called "cloaca-pecking." The female raises her tail exposing the cloaca. Instead of mating, the anticipating male pecks at the cloaca, an action that stimulates a pumping action and ejection of a droplet of sperm from previous matings. After the male inspects the droplet, normal mating follows. This ...
