This must be a coincidence, because the tidal forces exerted on the sun by distant Jupiter seem far too weak to disturb the sun's internal operations. (See details in ASO9 in The Sun and Solar System Debris.) Could it be that we are missing something, for there is some evidence that some planetary alignments also exert influence on the number of spots seen on the sun's face? In particular, the Uranus-Neptuneearth conjunction has been investigated by B. Payne, who wrote the following in Cycles: "Sunspots increase when two or more planets line up, an effect I have observed for more than a decade. During the last six years, Uranus and Neptune have been within a few degrees of each other. Their conjunction, which occurs every 137 years, is an ideal situation to validate the hypothesis that sunspot numbers are associated with planetary positions." Payne's lengthy analysis is omitted, but the essence of his study can be seen in the accompanying graph. He concludes: "The results clearly show that sunspot numbers increase markedly during Uranus-Neptune-Earth-sun alignments."

Yet, some of these colorful insects manage to flutter up to 4,000 kilometers from the eastern U.S . and Canada to their wintering grounds in Mexico. How do they do this? S.M . Perez et al have now shown that monarch butterflies are equipped with a sun compass; that is, they chart their courses by noting the sun's changing azimuth. This feat requires not only the measurement of solar azimuth but also reference to an internal clock. Humans cannot do this without artificial instruments. Furthermore, even on cloudy days, migrating monarchs fly in the proper direction (generally south-southwest). Apparently, they also have evolved a backup navigation system, perhaps a geomagnetic compass. (Perez, Sandra M., et al' "A Sun Compass in Monarch Butterflies," Nature, 387:29, 1997.) Comment. Somewhere in the tiny bodies of the monarchs are packed sun-azimuth sensors, internal clocks, magnetic-field sensors, and a nervous system that converts the incoming data into signals to the wings. Their genomes must also include map information to pass on to their progeny. From Science Frontiers #116, MAR-APR 1998 . 1998-2000 William R. Corliss ...

... Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects An exploded planet and the "face on mars"Between Mars and Jupiter swirls the main main asteroid belt. In the view of many astronomers, including T. Van Flandern, there resides the debris of an exploded planet. Van Flandern has adduced considerable evidence supporting the exploded planet hypothesis, which we will pass over in favor of a look at the possible effects of said exploding planet upon a large but equally hypothetical satellite of said planet. Such a satellite would have been heavily pelted by debris on the side facing the exploding planet. Furthermore, this battered sphere, having lost its gravitational "anchor," would assume a new orbit around the sun as well as a new orientation in space. Is there any object in the solar system plastered mainly on one side with debris and craters? You guessed it: Mars! What possible connection could there be between this purported cataclysm and the "face on Mars"? The connecting thread is very weak but so beguiling that we must mention it. T. Van Flandern has proposed eight tests for the artificiality of the "face" and its associated "pyramids," "city," etc. One is the three-dimensionality of the "face." Another is the "fractal" test, which is useful in distinguishing between artificiality and naturalness. The "face" readily passes four of the eight tests. A fifth test (bilateral symmetry) cannot be decided until we get more pictures. But failure looms on the last three tests (location, orientation, ...

For high hydrodynamic performance, their bodies must be nicely streamlined. For males, this means that their testicles must be stored internally. But dolphins are very active animals, and their muscles generate considerable heat -- too much heat for sperm to survive without some sort of special cooling system. (Recall that human males with undescended testicles may become sterile.) Since dolphins are obviously procreating, evolution must have come to the dolphins' rescue. Evolution's engineering solution installs heat exchangers in the dolphins' tails and dorsal fins. Blood heated in the vicinity of the testes is pumped through special veins in the tail and dorsal fin, where it is cooled by seawater and then returned to the dolphins' heat-sensitive innards. Female dolphins have similar heat exchangers to cool their uteri. The same article in Discover points out still another remarkable adaptation conferred on dolphins: They do not have to expend a lot of energy in diving to great depths. Below about 70 meters, the water pressure collapses their lungs so that they sink like rocks! Of course, returning to the surface does require some exertion.

These rings were equally spaced and expanded outwards for about 500 meters before disappearing. Rings with spoke systems also formed, rotating clockwise. The observers had the distinct impression that the rings were above the sea surface. We have reported on so many of these light wheels in the past 22 years that we have skimped on the details in favor of the comments made by P. Herring of the Southampton Oceanography Centre.

Superficially, it is a terraced earthen mound 100 feet high and more than three football fields long. What we now see of the mound was apparently constructed between 900 and 1200 AD. The prevailing dogma has long been that the Indians who built Cahokia worked only with earth, never with stone. Indeed, suitable stone is scarce in the area. On January 24, 1998, while drilling to construct a water drainage system at Monk's Mound, workers hit stone -- at least 32 feet of it -- perhaps a region of cobbles or slabs of rock. This region of stone, of undetermined geometry, is located 40 feet below one of the terrace surfaces, but still well above the base of the mound. The stones could well be an artificial structure of some sort. The discovery challenges the current thinking about the culture that built Cahokia. Only further research will reveal the extent and configuration of the stony region and where the stones may have come from. An editorial in the March 14, 1998, St. Louis Post-Dispatch put the Cahokia discovery in the larger context: New World archeology is in flux.

Frank and J.B . Sigwarth that the earth is bombarded daily by 30,000 house-size icy comets. If such bombardment has really been occurring, scientists would have to rethink the origins of the earth's oceans, terrestrial life, and the formation of the solar system. No wonder the icy-comet hypothesis is strongly challenged! Three of the more interesting points made by this group of papers are as follows: Our moon could not escape the icy-comet bombardment. Roughly 1,000 craters 50 meters in diameter and splashes of debris 150 meters in diameter must occur each. There is no evidence that the moon is thus afflicted. Comets also carry the noble gases argon, krypton, and xenon. These gases should accumulate in the atmosphere as the comets disintegrate. The amounts of these gases actually measured are 10,000 times less than those the postulated bombardment would produce. The icy comets should break up near the earth and produce clouds of ice crystals. Sunlight reflected from such 30-ton clouds would be brighter than Venus and easily visible before they disperse. Such objects are rarely seen, implying that small icy comets do not exist in the numbers claimed. Preceding this series of five ...

Believers respond that the fluid remedies somehow retain the "essence" of the active ingredient. In effect, they maintain that water has a "memory." No wonder mainstream scientists scoff at homeopathy. But wait, perhaps water can have a memory! A Cal Tech chemist has put extremely dilute solutions under his electron microscope and found that some contain strange "ice" crystals, even though room temperature and pressure prevail. Called "IE crystals," they are produced through the action of ions. They are stable even at higher temperatures. Subsequently, an immunologist at the University of California at Los Angeles discovered that the IE crystals can stimulate parts of the immune system. Water containing these strange forms of ice show a hundred times more bioactivity than plain water. (Anonymous; "Homeopathy and IE Crystals," Spectrum , p. 18, November/ December 1998. Cr. E.

... . Van Flandern advanced the theory that the rugged southern highlands are composed of the debris from an exploded planet which Mars once attended as a satellite. Be that as it may, there is something puzzling about the northern plains. We now have information from the Mars Global Surveyor (MGS), now orbitting the red planet, that the low-lying northern plains are much flatter than thought. For thousands of kilometers, they are smooth on a scale of hundreds of meters. This is flatter than the lava flows of the lunar maria; flatter than the smoothest central Sahara. These startling data come from the MGS's laser altimeter that can measure elevation of the terrain below it with 10meter accuracy averaged over the beam width of 150 meters. The only known terrain in the entire solar system that can match this flatness is the abyssal, sediment-filled floor of the South Atlantic. Hmmm! Does this imply that the northern plains of Mars were once an ocean floor? That's the favorite interpretation today. Of course, they might also be lava plains created by a colossal ancient impact, made smoother by blown dust. (Kerr, Richard A.; "Surveyor Shows the Flat Face of Mars," Science, 279:1634, 1998.)

Not only is the magnetic axis of Uranus tilted grotesquely away from the planet's axis of rotation, but the latter lies almost in Uranus' orbital plane. Q1. Why are the magnetic fields of Neptune and Uranus tilted at such grotesque angles with the axes of rotation? A1. Probably because of giant impacts. Q2.

... people claiming to have exceptional memories. In their second paper (Ref. 2), they detailed the mental workings of TM, a 25-year-old male, and an accomplished user of mnemonics. TM astounds audiences with his seemingly impossible memory feats. These feats, however, are no mystery to TM, and he has carefully explained how it is all mnemonics and nothing paranormal. But there remains the clear implication is that the normal human mind is underestimated and underused. TM's "performances" involve six demonstrations, two of which we now elaborate upon. Demonstration 2. TM asks audiences for birthdates and very quickly gives the day of birth. He has explained this "gift" thusly: "The day of birth calculations were originally carried out through use of a system of numerical codes for years and months which were combined and subjected to certain calculations. However, with practice many shortcuts and mnemonics have been developed and now TM often knows instantly that certain dates imply certain days, like learning the multiplication table. Every year and month has a code from 0 to 6 and TM has learned the codes (by the method explained below) for all years from 1900 to 2000. For any given date the method is to add the codes for the month and the year and divide the total by 7; the remainder gives the day of the week. For example, 27 October 1964 gives 27+ 1 (the code for October)+ 3 (the code for 1964) = 31. Dividing by 7 gives a remainder of 3 which is the ...

Chaosists seem to be able to find chaos everywhere they look. If you have ever ridden on that amusement park staple called the Tilt-A -Whirl, you will recall that the ride is fun because you never know exactly what the car you are riding in will do as the platforms move along the hilly circular track. Each car is free to rotate about its center and will also tilt in all possible directions as the cars go up and down the hills. Can one mathematically predict whether the car will spin clockwise, counterclockwise, or not at all? What a neat problem for a physicist! And two physicists, R.L . Kautz and B.M . Huggard, have developed a mathematical model of the Tilt-A -Whirl. By integrating the equation of motion, they find that the Tilt-A -Whirl is, indeed, a chaotic system.

Furthermore, archeology is more than shards and arrowheads. Today's physicists enjoy speculating about Theories of Everything, but they really don't nean everything ! They just mean physics and cosmology. Some 5,000 years ago, the Sumerians constructed a remarkable Theory of Everything based upon music, a base-60 number system, and symmetry concepts. These Sumerians didn't have supercomputers but they were able to incorporate into their theory much more than physics and cosmology. Below, E.G . McClain provides some insight into ancient Sumerian thinking: "In ancient Mesopotania,music, mathematics, art, science, religion, and poetic fantasy were fused. Around 3000 B.C ., the Sumerians simultaneously developed cuneiform writing, in which they recorded their pantheon, and a base-60 number system. Their gods were assigned numbers that encoded the primary ratios of music, with the gods' functions corresponding to their numbers in acoustical theory. Thus the Sumerians created an extensive tonal/arithmetical model for the cosmos. In this far-reaching allegory, the physical world is known by analogy, and the gods give divinity not only to natural forces but also to a 'supernatural,' intuitive understanding of mathematical patterns and psychological forces."

In fact, this conservative journal devoted almost an entire page to a paper presented by Yi-Jehng Kuan and Yanti Miao at the recent Minneapolis meeting of the American Astronomical Society. Students of L. Snyder, at the University of Illinois, Kuan and Miao reported that the amino acid glycine had been detected in a molecular cloud named Sagittarius B2. Glycine has only ten atoms and is the smallest of the 20 amino acids vital to life-as-we-know-it. The Science article supposed that this discovery of extraterrestrial glycine might reignite speculation that earth life might not be unique after all.

Where a cell or group of cells is permanently turned on, there is a dark stripe of pigment, and where the cells are dormant, there is an unpigmented space. The complementary pattern -- horizontal stripes, parallel to the growing edge -- results from a temporal rather than a spatial oscillation. All the secretory cells turn off and on in synchrony, so that light and dark bands are left behind on the surface of the shell as the growing edge moves on." All well and good, but some seashells have intricate patterns that require modellers to imagine traveling waves of excitation, oscillating chemical systems, signals that travel faster than chemical diffusion, and longrange synchrony employing a "global control element." These patterngenerating schemes are clever and rather successful on the theoretical level. Indeed, the seashell modellers are rather smug about their accomplishments. (Hayes, Brian; "SpaceTime on a Seashell," American Scientist, 83:214, 1995.) Comment. The seashell modellers, of course, do not have to explain how or why "global control elements" evolved. The biological rendering of "long-range synchrony" is left unexplained.

The complexity of the organic molecules found on these particles has fueled the imaginations of many who ponder the role extraterrestrial matter may have played in the prebiological evolution of organic material on the primordial Earth." Beyond these conjectures, several other things about interplanetary dust particles bother scientists: "' What is surprising,' Walker notes, 'and still not understood, is the fact that the organic molecules we see in the dust particles are different from those previously seen in meteorites.'

Since November 5, 1993, about 100 of these bursts have been detected by a special radio receiver named "Blackbird" mounted on the Alexis satellite. Most of the bursts have been recorded over Africa and South America, although they may also be frequent elsewhere but are drowned out by man-made radio noise from the ground. The bursts come in pairs that are separated by 40 microseconds. The frequency dispersion of the bursts indicates that the signals have passed through the earth's ionosphere before reaching the satellite.

... as a surprise when we find supposedly primitive organisms employing our highly technical concepts; for example, the jamming-avoidance techniques of electric fish (SF#89). Still another potential example has been advanced: The lowly crayfish is now thought to enlist some of our sophisticated information theory. Crayfish often live in noisy environments, where one would expect acoustical information transmission would be degraded. This would be true enough if linear information theory applied, but some, perhaps all, real situations are nonlinear. In such instances, information flow can actually be enhanced by the presence of optimized random noise. Stochastic resonance (SR) is the term applied in such cases of nonlinear statistical dynamics. J.K . Douglass et al write: "Although SR has recently been demonstrated in several artificial physical systems, it may also occur naturally, and an intriguing possibility is that biological systems have evolved the capability to exploit SR by optimizing endogenous sources of noise. Sensory systems are an obvious place to look for SR, as they excel at detecting weak signals in a noisy environment. Here we demonstrate SR using external noise applied to crayfish mechanoreceptor cells. Our results show that individual neurons can provide a physiological substrate for SR in sensory systems." Put more simply, the crayfish nervous system has the potential for cashing in on SR in noisy environments. However, the authors also remark that humans, too, accordingly to psychological experiments, seem to harness SR in the perception of ambiguous figures in noisy situations.
