... admit an inability to predict planetary motion over billions of years - even tens of millions of years! For the solar system, if those ubiquitous computers are correct, is not a well-behaved family of planets. J. Laskar concludes from extensive numerical experiments: "The motion of the Solar System is thus shown to be chaotic, not quasiperiodic. In particular, predictability of the orbits of the inner planets, including the Earth, is lost with a few tens of millions of years." (Laskar, J.; "A Numerical Experiment on the Chaotic Behavior of the Solar System," Nature, 338:237, 1989.) Comment. Laskar's comments are directed toward the future, but the same conclusions should apply if we ran the solar system backwards in time. From this very narrow perspective of celestial mechanics, one cannot say positively that the planets, the inner ones especially, could not have radically altered their orbits within the past few millions of years.

While Time implies that all crop circles are hoaxes, the Science article states that the "really bizarre" circles are hoaxes and that the simpler circles may have acceptable meteorological explanations. Unfortunately, the ridiculing tone of the Time article will probably set back the budding scientific interest in crop circles reported in Science. The real losers, as we shall see below, are those crop-circle experts who assert that they can always detect hoaxes. Essence of the Time article. Two cropcircle hoaxers have confessed. D.

All they needed was a 4-foot wooden plank, a ball of string, and a baseball cap with a wire mounted on it for sighting purposes. It was all too easy! And, they assure us, other hoaxers were active in fields at night, too. This is indeed damaging evidence to crop-circle enthusiasts.

Fairbanks is a paleooceanographer at the Lamont-Doherty Geological Observatory. Recently he has been drilling deeply into the submerged coral reefs off Barbados. During his research, it has been discovered that the radiocarbon (C1 4 ) scale is in serious error beyond 10,000 years BP. Radiocarbon dating is widely used in archeology, but it has always been hard to estimate how much radiocarbon was present in the earth's atmosphere thousands of years ago. As a matter of fact, even before Fairbanks' discovery, a major correction to the radiocarbon time scale was made using tree-ring counts as an absolute reference. But tree ring data go back to only about 10,000 years. The latest correction was made by E. Bard, also at Lamont-Doherty, who took Fairbanks' coral cores and compared the radiocarbon dates with uranium-thorium dates. The result is that at 20,000 BP, the radiocarbon date is 16,500 BP, 3500 years too low. [Of course, all this as sumes that the uranium-thorium dates are accurate.] Use of the newly corrected radiocarbon scale has pushed the peak of the Ice Ages back from 18,000 BP to 21,000 BP.

Indeed, all of the reference books confidently label charts with firm dates for the appearance of fishes, the demise of the dinosaurs, and so on. Alas, things are not quite as certain as they appear. Radiometric dating is not all that precise; errors may be large indeed. Take the Pennsylvanian period for example. It is part of the Carboniferous period, when many of the great coal deposits were laid down. The classical duration of the Pennsylvanian -- used in many texts -- is 34 million years. A meticulous new study of central European stratigraphy now pegs the Pennsylvanian as spanning only 19 million years. Now that's a 44% change! This new figure for the duration of the Pennsylvanian has already cast doubt on the origin of the famous Pennsylvanian cyclothems (repetitive strata) in North America. It had been thought that these seemingly cyclic deposits were correlated with sea level changes forced by variations in the earth's orbit (the Milankovitch periods). With this substantial compression of Pennsylvan-ian time, this correlation falls apart. The cyclothems, which are of impressive area and thickness, now seem to have been created by some other, still unrecognized phenomenon. (Klein, George deV.; "Pennsylvanian Time Scales ...

R.E . Gentet sets the geological stage in the following paragraph. "The 1849 gold rush to the state of California was the beginning of some of the most unusual reported finds of early man in North America. The gold-bearing gravels of California are recognized as being Tertiary in age, ranging from oldest to youngest Tertiary, depending upon the exact geological setting. At the time these gravels were deposited, volcanic eruptions also laid down lava beds, often tens or scores of feet thick. This occurred a number of times, and together with much erosion since then, have now resulted in table mountains, that is, lava-capped hills where the harder lava has better withstood erosion stresses while surrounding softer material has been swept away. It is under the hard lava beds, in the gold-bearing (auriferous) gravels, where the reported human bones and artifacts were found, not just once or twice, but hundreds of times by miners during the span of time from the 1850s through the 1890s while engaging in mining operations. Findings were spread over a wide geographical area." During the late 1800s, several books and many papers recorded the discoveries. Some of the finds were made by respected scientists of the day.

Although experts prefer to avoid simplistic definitions of intelligence, it seems clear that all intelligence involves the rational manipulation of symbolic information. This is exactly what happens when army ants pass information from individual to individual through the 'writing' and 'reading' of symbols, often in the form of chemical messengers or trail pheromones, which act as stimuli for changing behavior patterns." During its 20-day stationary phase, an army ant colony scatters about 14 foraging raids directed 123 apart. The heavy line indicates the colony's path during the nomadic phase. In the body of his article, Franks describes two remarkable capabilities of an army ant colony: time-keeping and navigation. The outward manisfestation of time-keeping is in the precise timing of the colony's nomadic phase of 15 days (during which larvae are growing) and the 20-day stationary phase (during which pupae develop). The queen's egg-laying also conforms with this schedule. Raids into the rain forest occur in both phases. Perhaps more remarkable is the systematic orientation of the raids in the stationary phase. These raids are separated by an average 123 , as diagrammed. This scattering allows time for new prey to enter the previously raided areas. But how does the colony determine direction in the dense rain forest? Probably from polarized sinlight, thinks Franks. But here we have a problem: each army ant, instead of having multi faceted ...

Rather, J. Maddox, the Editor of Nature, raised that red flag. To make things even worse, he subtitled his editorial: "Apart from being philosophically unacceptable, the Big Bang is an oversimple view of how the Universe began, and it is unlikely to survive the decade ahead." His philosophical objcections to the Big Bang are powerful: "For one thing, the implication is that there was an instant at which time literally began and, so, by extension, an instant before which there was no time. That in turn implies that even if the origin of the Universe may be successfully supposed to lie in the Big Bang, the origin of the Big Bang itself is not susceptible to discussion." The Big Bang, Maddox says, is no more scientific than Biblical creation! The scientific objections involve space, time, the curvature of space. The Big Bang further fails at explaining quasars and the hidden mass of the Universe. Maddox doubts that the Big Bang will survive the new data to be provided by the Hubble telescope.

Similar but much smaller "microtektites" appear in deapsea de posits in the adjacent oceans. Radiometric and fission-track dating indicate that the tektites solidified about 700,000 years ago. Yet, their geological age, as measured by the age of the terrestrial sediments in which they are found, is only a few thousand years. This great disparity in age engendered a confrontation between geologists and geophysicists. The latter insisted on their 700,000-year figure; the former said "maybe so" but the tektites are still found only in very young, superficial sediments. The point here is that time-of-solidification may not be the same as time-of-fall. At stake is the prevailing theory, now dogmatically proclaimed, that tektites are created when a large asteroid impacts the earth, ejecting molten droplets of rock which shower back to earth as solidified tektites. No one has ever found a suitably large crater ( 200 miles in diameter) assignable to the Australasian tektite strewn field. Nevertheless, the impact model prevails; and the young geological age of the tektites is dismissed as erroneous. A Soviet scientist, E.P .

Here, let us assume that it really does exist, even though we cannot see it. From a new book by I. Asimov (title below), we learn that this remote haze of icy fluff, the Oort Cloud, may really have about 90% of the angular momentum of the entire solar system. It was already sufficiently anomalous to discover that the planets possess fifty times the angular momentum of the much more massive sun. (See ABB3 in The Sun and Solar System Debris.) Astronomers have been attempting for years to explain this 50:1 split. Now, with the Oort Cloud apparently having ten times the angular momentum of the planets, the situation is much worse. According to Asimov, the solar-system angular momentum is split as follows: Oort Cloud 90% All of the planets 9.8 % The sun 0.2 % The total mass of the Oort Cloud is estimated to be roughly that of Saturn. The recent flyby of Halley's Comet created this dilemma. It was discovered that Halley was a chunk containing 140 cubic miles of ice - much larger than anticipated for this "typical" comet.

From this, they carved a lion with a human head out of the soft natural rock. Once the soft limestone was exposed, the rain and atmosphere began to erode it. R.M . Schoch, a Boston University geologist, studying the weathering patterns on the Sphinx, found signs of water action up to 8 feet deep in the front and sides of the colossal statue. Other structures in the vicinity, made from the same limestone, supposedly at the same time (about 2500 BC), do not display such deep erosion. Based upon the depth of the weathering, Schoch dates the Sphinx at 5000-7000 BC -- much older than the mainstream date of 2500 BC. In fact, Schoch opines that work on the Sphinx could have begun as early as 10,000 BC. Egyptologists, of course, will have none of this. C.

These individuals are self-taught and do not follow procedures at all similar to the usual, published, algorithms. An investigation of one individual revealed that he retained considerable information about the structure of days in particular months, probably as visual images. His skill closely depended on the extent and form of his knowledge of calendars, and his errors were often a consequence of lack of knowledge about a particular time period. Mentally retarded individuals who perform calendar date feats are often socially withdrawn and devote considerable periods of time to calendar dates.

This is Periodic Spring, whose intermittent flow is a rare geologic phenomenon. The water is cold and clear, an indication that this is not a geyser like Old Faithful; such geysers, of volcanic origin, send forth hot water. Through the years various observers have timed the flows at anywhere from four to twentyfive minutes, with similarly varying dry spells. The intermittent flow is especially regular in late summer and autumn. During stormy periods or when there is heavy snow melt-off, the flow fluctuates but does not stop entirely."

Persinger and S. Krippner. "The 24-hour periods in which the most accurate telepathic dreams occurred during the Maimonides studies displayed significantly quieter geomagnetic activity than the days before or after. This statistically significant V-shaped temporal sequence in geomagnetic activity was not evident for those periods when less accurate dreams occurred. When geomagnetic activity around the time of the strongest experimental telepathic dreams was compared to the geomagnetic activity around the time of spontaneous telepathic dreams from the Gurney, Myers and Podmore (1886) collection, very similar (statistically undistinguishable) temporal patterns were observed. Analyses of both experimental and spontaneous telepathic experiences indicated that they were more accurate (or more likely to have occurred) during 24hour intervals when the daily average antipodal (aa) index was approximately 10 3 gammas. When the daily aa index exceeded amplitudes of approximately 20-25 gammas, telepathic experiences became less probable." (Persinger, Michael A., and Krippner, Stanley; "Dream ESP Experiments and Geomagnetic Activity," American Society for Psychical Research, Journal, 83:101 1989.) Comment. It must be added here that mainstream science does not (yet) admit that telepathy exists as a legitimate scientific phenomenon. Nevertheless, there is an immense literature on telepathy and related parapsychological subjects. Once again we have a "shadow science," with ...

Moriarity cites Pliny as the earliest historical reference. According to him, Eel Balls occur in Lake Garda, Italy, when it has been storm-tossed by the effects of the October 'Autumn star'. Smitt in his Scandanavian Fishes (1895) says that eels knot themselves together in bunches 'up to a fathom in circumference' and are seen rolling along the stream beds, or, strangely, resting in this position. On 17 August 1935, fishery scientist J.C . Medcof observed, in the outflow of Lake Ainslie in Nova Scotia, 'three splendid clumps of Eels, half a metre in diameter, 30 to a clump, knotted tightly and remaining motionless in the rushes.' Medcof mentions that Eel Balls are sometimes free floating on the surface, which suggests formation with an air pocket or some communal control of air bladders. He says that this behavior occurs before eels 'silver' prior to the spawning migration. The record of Eel Balls in Nova Scotia proves that this behaviour is not confined to the European Eel." ( ...

Together, they have conspired - in a vegetative way - to exterminate the pandas. Why pick on such a cute, lovable animal? Pandas, you see, eat nothing but bamboos; and the bamboos have had enough! The bamboos' strategy is to flower only once in a lifetime. When the appointed time arrives for each species, all plants of the species all over the world flower simultaneously. The various species flower at intervals of 15, 30, 60, or 120 years. (These 15-year multiples and the unknown clocks that determine them are anomalies in themselves.) After a species flowers, all plants die, leaving the fate of the species to a thick carpet of seeds. Until the next flowering, it will extend its domain via vegetative reproduction only. Ten years will pass before the bamboos have grown enough to be a viable pan-da food source. The pandas' only hope is to find a species of bamboo that did not flower. It is hard to think of a plant as malevolent, but here is how P. Shipman describes the situation: "Green and slender, deceptively innocent-looking, it spreads out slowly, year by year, until it has its victims surrounded.

But the K-T boundary is anything but simple chemically and paleontologically. To illustrate, J.L . Bada and M. Zhao have found unusual amino acids in sediments laid down before and after this geological time marker. "They find that Danish sediments spanning the narrow boundary layer contain two amino acids, alpha-aminoisobutyric acid and isovaline, that are relatively uncommon in biological materials but abundant in the organicrich meteorites. They suggest that the body which collided with Earth 65 million years ago and left the telltale iridium residue may have been organic-rich, perhaps like a C-type asteroid or a comet. Such a possibility has interesting implications for the extinction and related atmospheric effects, and supports the idea that impact events could have supplied the Earth during a much earlier period with the raw materials for organic chemical evolution." Actually, the above quotation is pretty much in line with present mainstream thinking. Perhaps so, but Bada and Zhao identified two troubling anomalies. First, the amounts of amino acids found were surprisingly high. How could these complex molecules survive the searing temperatures engendered by high-velocity impact? Second ...

The emerging baby echidna has an egg tooth like the birds and reptiles, while the adult has no teeth at all. Rather, it has a narrow snout through which it ingests ants and termites caught on its sticky tongue. In this it resembles the mammalian ant-eaters, which are also toothless but an ocean away from Australia. In fact, the echidna is often called a "spiny anteater" for it has the sharp spines of a hedgehog or porcupine. There are more anatomical peculiarities, but let us focus on the echidna's strange behavior during the mating season. At this time, 2 to 8 echidnas can be seen roaming the Australian bush in "trains" headed by a female with the smallest male acting as a caboose. When mating time arrives, the female anchors herself to a tree with her forelegs. To-gether the males dig a circular "mating rut" up to 10 inches deep around the tree. (Australians have puzzled over these circular trenches for years.) Eventually the strongest male evicts the other males from the trench, the purpose of which now becomes apparent.

The causes and geological significance of this phenomenon have been much debated." The foregoing paragraph is enough to send shivers throughout the geological world. Does this undermine paleomagnetism and generalizations flowing from it, such as plate tectonics? The "alteration processes" mentioned in the above quotation include: (1 ) The chemical conversion of pyrite into magnetite in ancient rocks after they were deposited; and (2 ) The reorientation of remanent magnetization following exposure to moderately high temperatures. That these processes can be important is evident in a second quotation: "During the past eight years, however, evidence has accumulated that the remanent magnetization of many carbonate sediments was not acquired at the time of deposition, thereby invalidating some previous interpretations of the palaeomagnetic data. Instead, magnetization seems to have been acquired over a limited time span during the late Palaeozoic, from about 310 to 250 million years ago."

Eruptions of Old Faithful Geyser are generally perceived as extremely regular events, with variation of eruptive interval being attributed to random noise. The governing equations for such a hydrothermal system are highly non-linear, therefore it is reasonable to assume that such systems are capable of operating in regines that display chaotic behavior. Three-dimensional state-space reconstruction of eruption time data provides strong evidence of a strange attractor quite similar to the Rossler attractor. Establishing the system as chaotic indicates that while one can predict eruptive intervals in the short term, long term predictions regarding Old Faithful's eruptive behavior are impossible, no matter how carefully and accurately the system is modeled. The mean eruptive interval of Old Faithful has changed over time. This is consistent with the behavior of a chaotic system, which by definition must be nonstationary in the mean. Seismic activity is believed to be a perturbation shifting Old Faithful into a new chaotic state with a different shape to the strange attractor. A simple non-linear dynamic model of geyser behavior is proposed that leads to chaotic behavior and is consistent with the observations of eruption interval data for Old Faithful."

Now that cell-surface DNA can be talked about, we can wonder aloud where it comes from and what its significance is.

It also seems they knew how to sail the deep ocean, as G.F . Carter now relates. "Decades ago, Gutorn Gjessing pointed out that the identical [Red Paint] culture was found in Norway. No one paid much attention to that, but more recent carbon-14 dating has shown that the identical cultures had identical dates, and people began to pay more attention. It is now admitted that this is a high latitude culture that obviously sailed the stormy north Atlantic and stretched from northwest Europe over to America. It seemingly extends from along the Atlantic coast of Europe to America and in America from the high latitudes of Labrador down into New York state. "The dates are mind-boggling: 7,000 years ago both in Europe and America. That is 2,000 years earlier than the Great Pyramids of Egypt. It is at least 4 ...

... flying triangles." Our invitation to our European readers to expand on this "flap" brought numerous articles from European papers and magazines. Normally, we bypass UFOtype observations, but the Belgian flying triangles are so remarkable that they deserve a little space. Artist's concept of the Belgium Flying Triangle, with three white lights on the corners, one red light in the center. (From: Télérama , February 21, 1990.) Very briefly, we have roughly 1000 observations by several thousand people, beginning in October 1989 and still continuing. Most witnesses report a dark, triangular object with three bright lights plus a flashing red one in the middle. Size estimates vary from the size of a football field to that of conventional aircraft. The object sometimes hovers for minutes at a time. It also can move very slowly and then suddenly accelerate to high speeds. Some observers report a faint humming sound; others say that it is noiseless. The American Stealth fighter (Fll7) is roughly triangular, and there has been much speculation that people have been seeing this craft on night missions. The characteristics reported for the flying triangle, however, are hardly those of a jet aircraft. But one must always remember that human observers are imperfect. The July 5, 1990, issue of Paris Match presented a remarkable account of an encounter between two Belgian F16s and one of the flying triangles. We use here those portions of a translation provided by R.J . Durant to the Internation al UFO Reporter (15:23, July/August 1990). "On ...

The pendulum's length was 25.008 meters; its spherical bob weighed 5.5 kilograms. The eclipse commenced at 8h 49m 3s and terminated at 11h 16m 50s.

"At that moment a surprising fact occurred, the pendulum produced a perturbation by describing an ellipse whose major axis deviated in relation to the initial plane by approximately 15 . The eccentricity of the ellipse was 0.18. At the end of the eclipse the pendulum continued to maintain the elliptical oscillation, but the major axis approached increasingly to its initial plane."

"Japanese and British meteorologists are investigating a link between a fastmoving object crossing the Pacific and the mysterious appearance of crop circles in English fields. "A ship from Tokyo University's Ocean Research Institute was in the Pacific when its radar equipment located a large object travelling more than four times the speed of sound. The radar discounted it as an aircraft because of its size, 400 metres across, and it sped northwards. "The Japanese scientists identified the object as a plasma vortex, caused by freak weather. The phenomenon is similar to ball lightning and believed to be generated by 'mini-tornadoes' of electrically-charged air. "Plasma vortices can be luminous at night.

Monte Verde, Chile. Another recent issue of Science reviews the first of two volumes on the Monte Verde site. This volume deals with the site itself. The artifacts themselves are reserved for Vol. 2. The reviewer states: "Even without a detailed consideration of artifacts and cultural features, it presents convincing evidence of 12,000-to-13,000year-old human occupation in southern Chile." If these ancient Chileans came across the Bering land bridge no earlier than 12,000 BP, they made excellent time down to Monte Verde!

If the thoughts of a human experimenter can affect marine algae (p . 000), why not electrical equipment? Of course, we know why not! But we have heard some pretty weird stories! For that matter, can you account for everything your computer does? "A strange new phenomenon has recently been studied in detail for probably the first time. It is street lamp interference, or SLI. Author Hilary Evans, a founder member of ASSAP, has established SLIDE, the Street Lamp Interference Data Exchange, to study the reports. "SLI is the apparent ability that certain people have to switch street lamps on or off merely by being in their vicinity. While it may seem to be a form of psychokinesis, Hilary insists that no conclusion should yet be drawn from the small body of data so far accumulated. The effect is surprisingly common, though most reports so far have come from the USA. ASSAP, in cooperation with SLIDE, now wants to obtain information on the phenomenon in Britain."

... Scientific creationists often point out marvels of biological engineering as proofs that evolution by small chancedirected steps is, to say the least, improbable. A sharp arrow for their qui ver has just appeared in Science. Caterpillar-ant vibrational communication. Some species of caterpillars cannot survive predation unless they are protected by ants. To attract the ants, who just happen to dote on special secretions of the caterpillars, the caterpillars send out vibrational signals across leaves and twigs. In addition to their secretory structures, the caterpillars have also evolved novel vibrators to send out their calls for protection. A few butterfly species from all continents (except Antarctica) have evolved these devices. Looking at this geographical spread, P. J. DeVries thinks that the two sets of organs must have developed independently at least three times .
