But Antarctic explorers, within the last few decades, found that thousands of meteorites have been concentrated in the ice of the southernmost continent. Even more recently, the desolate, desert-like Nullarbor (" no-trees") Plain, in Southern Australia, has been discovered to be another concentrated source of of meteorites. There may be millions there. The problem is that only 2.9 % of them are iron meteorites, whereas those picked up in recent years around the planet-atlarge are 4.8 % irons. The meteorites from the Antarctic lode, on the other hand, weigh in with only 2.2 % irons. Why the marked differences? Could it be age? The Antarctic meteorites seem to be up to a million years old; those of Nullarbor, perhaps 16,000-18,000 years. (Anonymous; "A Meteorite Bounty from Down Under," Sky and Telescope, November 1991.) Comment. Perhaps pertinent is the observation that fossil meteorites are essentially nonexistent in geological formations older than a million years. This is an anomaly of itself!

This assertion was challenged in SF#66, where an origin in southeast Asia was championed. Now, it's Greece! "The immediate ancestors to the human family - the hominids - might have been living in Greece, rather than Afica, some 10 million years ago in the late Miocene, according to the French palaeontologist Luis de Bonis. "In September 1989, de Bonis and George Koufos of the University of Thessaloniki discovered the fossilized face of an ape-like creature, Ourano pithecus, at a site in the Valley of Rain, 40 kilometres northwest of Thessaloniki. Although the fossil has not yet reached the scientific press, de Bonis has publically described it as a possible precursor of the earliest known hominid species, Australopithecus afarensis , from Africa 3.5 million years ago."

As these Indians go about their fishing, wood chopping, and honey gathering, tigers are wont to sneak up from behind, spring, and carry off a good-sized meal. But in recent experiments, some 900 volunteers have been wearing human masks on the backs of their heads. This strategem has cut ti-ger attacks drastically. The idea is that tigers, trailing a potential supper, see that human face and figure that the person is alert and watchful.

You can add the 1990 flu outbreak to the curve yourself! To strengthen the correlation Hoyle and Wickramasinghe tabulate flu and sunspot data back to 1761. They find that flu pandemics and sunspot maxima have kept in step for the last 17 cycles. Key to the Hoyle-Wickramasinghe argument is their contention that simple life forms (viruses, bacteria, etc.) not only exist in outer space but likely evolved there. If so, how do they ride in to afflict us on the peaks of the solar cycle? Here's how, in their words: "In conclusion, we note that electrical fields associated with intense solar winds can rapidly drive charged particles of the size of viruses down through the exposed upper atmosphere into the shelter of the lower atmosphere, ...

Similar bacteria have recently been discovered living in ordinary soil in Bavaria. It is near-certain that they will now be found just about everywhere. J.W .E . Fassbinder et al, who reported the Bavarian bacteria, conclude their Abstract with: "We suggest that the magnetic bacteria and their magnetofossils can contribute to the magnetic properties of soils." (Fassbinder, Jorg W.E ., et al; "Occurrence of Magnetic Bacteria in Soil." Nature, 343:161, 1990.) Comment. It is easy to reach great heights of speculation given the facts that: (1 ) magnetic bacteria exist; (2 ) bacteria in general are exceedingly abundant; and (3 ) bacteria are found deep inside the earth's crust and, seemingly, just about anywhere one cares to look. Now, let's see how ridiculous one can get: Magnetic bacteria and/or their fossils contribute heavily to the magnetic properties of sedimentary rocks and unlithified sediments, such as deep-sea sediments. In fact, magnetostratigraphy and paleomagnetism in general may be based upon bioartifacts and be suspect. Magnetic bacteria and/or their fossils are present in such immense ...

Accidents. "Left-handed people are almost twice as likely to suffer a serious accident as right-handers, according to a recent study. Stanley Coren, an experimental psychologist at the University of British Columbia in Vancouver, Canada, claims that his finding helps to explain why less than 1 per cent of all 80year-olds are 'southpaws,' whereas they comprise nearly 13 per cent of all people aged 20." Coren surveyed students at his University for four years and found that the probability of a left-hander having a car accident was 85% higher; accidents with tools were 54% higher; home accidents were 49% higher; etc. Coren blames these lopsided statistics upon the fact that the world is ordered for right-handers, not that left-handers are innately more clumsy. (Dayton, Leigh; "The Perils of Living in a Right-Handed World," New Scientist, p. 32, October 28, 1989.)

Stothers, at NASA's Goddard Institute for Space Studies, decided to look into the possible correlation of solar activity and terrestrial volcanism, he fully expected to find no connection at all. After all, what force generated by small changes in the sun's output could stir up the earth's magma from a distance of 93 million miles? Stothers was surprised. "Stothers analyzed two immense catalogs, published in the early 1980s, that list more than 55,000 known eruptions since the year 1500. Concentrating on several hundred of the moderate-to-large eruptions, he found statistically significant patterns in eruption frequency that match the solar cycle. Eruptions seemed most numerous during the weakest portions of the solar cycle." Further, there was a 97% confidence that the correlation was not a statistical accident. The only cause-and-effect explanation offered by Stothers was negative and indirect. During periods of abundant sunspots, increased solar emissions jar the earth's atmosphere slightly. Communicated to the crust, these slight taps trigger tiny earthquakes that relieve stresses beneath volcanos, thus delaying their eruptions until solar acitivity dies down. Not especially convincing! (Anonymous; "Volcanos on Earth May Follow the Sun," Science News, 137:47, 1990.) Comment. Down the years, many scientists and laymen have tried to correlate sunspots and earthquake frequency ...

Of course, modern activities have obliterated them completely; and even in Hubbard's day they were mostly gone. First, Hubbard's general description of the "garden beds": "The so-called 'Garden Beds' were found in the valleys of the St. Joseph and Grand Rivers, where they occupied the most fertile of the prairie land and burr-oak plains, principally in the counties of St. Joseph, Cass and Kalamazoo. "They consisted of raised patches of ground, separated by sunken paths, and were generally arranged in plats or blocks of parallel beds.

They may be forced to take the phenomenon more seriously, because two new reports of redshift bunching have surfaced. First, B.

Ob-viously the Principle of Superposition is contradicted in such situations. Two possible explanations exist for these inverted strata: (1 ) The dating of the rocks is incorrect; or (2 ) Geological forces somehow slid the older rocks over the top of the younger rocks. Few mainstream scientists give any thought to the first possibility because it implies that evolution did not proceed as presently envisioned. (Rocks are often dated by their fossil contents.) So, geologists are left with the problems of sliding great masses of rock over rough surfaces for great distances. Sketch of the forces acting upon a thrust block being pushed by a wedge-shaped driver Low-angle thrust faulting is not a trivial geological process. To illustrate, the Lewis Overthrust in Montana and adjacent Canada involves the shoving of a block of old strata hundreds of feet thick, hundreds of miles long, over younger rock for a distance of possibly 50 miles. In contemplating such overthrusts, one immediately comes face to face with the Mechanical Paradox. Brief-ly, given the coefficient of friction between the layers of rock, the weight of the thrust block, and the mechanical strength of the rock being pushed, it can be shown that pushing the thrust block at the rear edge will crush it long before it begins to slide.

Rather, suggest M. M. Grone and M. Sher, the universe-as-a -whole may undergo a phase change. Such an event has already happened once and it may again. Approximately 10-10 seconds after the Big Bang, the force laws changed discontinuously as the universe cooled. Some models of the cosmos predict that another such phase change may occur when photons suddenly acquire mass. Grone and Sher have sketched the effects on terrestrial civilization: "The most dramatic effect would be the elimination of all static electric and magnetic fields over a range greater than 1 cm, and the elimination of all electromagnetic radiation with frequencies smaller than a few hundred gigahertz. We have shown that there would be relatively little impact on atomic structure and on solar radiation. The absence of electrostatic fields would force a redesign of current power plants (to use smaller solenoids); the absence of radio and television waves would force a much greater use of cables. The elimination of solar and geomagnetic fields would have a significant meteorological impact. The potential ly most devastating effect could be on the propagation of neural impulse along motor neurons; it appears that the effects might be small, but they do depend on the precise value of the photon mass."

Their physical appearances, habits, vocations, health histories, and other factors are often eerily the same. For example, two female identical twins, who had never seen each other, each wore eight rings! The upshot of such investigations is that most of a person's characteristics are genetic in origin; that is, Nature dominates nurture. But what about identical twins who are remarkably different? They can, for instance, differ appreciably in size, intellect, and behavior. In such cases, does nurture dominate nature? No! Identical twins may diverge even in the womb, where one may receive more oxygen and nutrients than the other. One also may be assailed in by viruses, bacteria, or drugs, while the other escapes. Even more drastic is the possi bility that one twin may pick up an extra chromosome soon after the original egg has split. Also, mutations may doom one twin to Down's syndrome or some other genetic affliction, while the other is unscathed. Identical twins may even be of different sex! Of course, such twins are genetically different, but they are still monozygotic (from the same egg). Blood tests will show them to be identical. It used to be thought that the small ...

Most were small, but a strong foreshock (magnitude 4.8 ) occurred on November 23; the main quake (magnitude 6.5 ) hit 60 hours later. Through appeals by radio and newspapers, 52 observers of EQLs were located. They reported a wide spectrum of luminosities, some of which were very strange. In the sky, some observed silent sparkings, diffuse glows, and aurora-like stripes. For an account of the more enigmatic EQLs, we quote M.

Others were seen several hundred metres up in the sky, stationary or moving. Some observers described dripping luminescent droplets, rapidly disappearing a few metres under the stationary fireballs. Only two fire-tongues on the ground were reported, one on snow and the other on a paved parking space without any apparent surface fissure.

Like its relative, the platypus, it is a strange mixture of mammalian, marsupial, and reptilian characteristics. For example, echidna eggs are soft and leathery, like those of reptiles, but they are brooded in a marsupial-like pouch. 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.

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." ( ...

After examination and measurement, the patterns of its carefully inscribed markings are believed to be identifiable as a calendar fashioned for use at Stonehenge.

Humphreys reviews a book that is just too expensive for us to consider buying. The title is: Synesthesia; A Union of the Senses . It costs $75 and is published by Springer/Verlag. The review, however, is expansive and provides some facts about synesthesia worth passing on to our readers. Syesthesia is an "oddity" of human perception in which words, musical instruments, objects, concepts, evoke sensations sharply different from what is actually being processed by the brain. For example, specific musical tones elicit specific color sensations; that is, B-flat evokes the color green; A-sharp, yellow, etc. Or the phenomenon may be more complex, with Mozart being green; Wagner, red, etc. Most "synesthetites" seem to experience colors, but geometrical figures sometimes appear in response to particular stimuli. As for the stimuli that call forth these exotic sensations; they are usually music or numbers. To some synesthetites, the cardinal numbers are associated with specific colors.

"I came out of the house about 6:25 AM to perform a task and, being an amateur astronomer, I looked up at the sky to see what was visible. I noticed the crescent of the waning moon appeared as a double crescent. My eyes kept trying to resolve it into a single image, but it wouldn't resolve. I then looked at several other light sources (radio tower, porch light, & street light) and determined that my vision was probably fine, as these objects appeared as single images. Looking back at the moon, it still appeared as a double image. I covered the right eye and I still saw a double image. I did the same with the left eye and got the same results. I then held out my right arm and extended my thumb to cover one crescent. I saw only one image that way. I moved my thumb and the image was again doubled. I concluded that I was viewing refracted images of the moon. "Conditions prevented continuous observation, but I was able to return approximately every five minutes. By 6:55 AM the sky was brightening and there was only a single lunar crescent. ...

Percipients describe the hum as like a "diesel truck with its engine idling." The electronic environment of Britain has been blamed for the hum: transformers, high-voltage transmission lines, and pulsed radars are all candidate hum-makers. For, it has been discovered, some people somehow convert pulses of electromagnetic energy into a perception of sound. This facet of the British "hum problem" was covered on p.000, where the infamous Soviet "Woodpecker Radar" is mentioned specifically. But are electromagnetic pulses really to blame? The British hum has become a nuisance - to those who can hear it - during the past 20 years. This is just the period during which British Gas has been installing a nationwide gas-distribution system, which employs powerful turbines to pump natural gas through underground pipelines. H. Witherington, an unhappy hum-hearer, has for years driven around Britain at night when things are quieter, plotting places where the hum can be heard.

We are talking 50-foot sharks and larger here; sizes that make the hero (or heroine) of the Jaws series seem minnow-like. All of these hints come from the Pacific and focus on the possible survival of the shark Carcharodon megalodon , a monster relative of the great white shark. Megalodon is thought to have met its demise a million or so years ago. The word megalodon means "big tooth," and indeed the fossil teeth of this monster approach 6 inches in length. Sharks sporting teeth of this size could be as long as 50 feet. Measurements of the manganese dioxide layers accumulated on megalodon teeth dredged up from the seafloor suggest that it might actually have survived the Ice Ages and terrorized the Pacific as late as 10,000 years ago. Actually, some unfossilized teeth 5 inches long have been brought up by dredges, implying an even more recent existence. Do scuba divers have anything to fear today?

T. Gold has contributed a rather plaintive article to the Journal of Scientific Exploration detailing some of his experiences down the years. His first "bad" experience occurred just after the end of World War II when, fresh from intensive work in radar signal processing, he proposed that the human ear is an active rather than passive receiver; that is, it actually emits sound itself. This self-generated tone aids the ear in signal processing. The thought that the ear could be a sound source was patently ridiculous, and Gold's idea got nowhere. However, recent experiments confirm that the human ear does indeed emit a tone at about 15,000 Hz. Another, more recent, proposal for research on the behavior of hydrocarbons under high temperatures and pressures got very high marks from reviewers on all points but one: Should the proposal be funded? Several reviewers thought not; one saying that the whole idea was "misguided." In what way was Gold misguided? Well, it seems that his proposed work on hydrocarbons related to his idea that primordial hydrocarbons deep in the earth's crust contribute heavily to the reservoirs of oil and methane we tap on the planet's surface. And everyone knows that all oil and gas is biogenic; that is, derived from buried organic matter! Gold has ...

When spun clockwise, as viewed from above, no weight changes were observed. But rotating at 13,000 rpm counterclockwise, the 175-gram gyroscope lost about 10 milligrams. The balance's sensitivity was 0.3 milligram. This is a very large effect; and the weight loss increased linearly with increased speed of rotation.

To be sure, corals built the Great Barrier Reef and beavers left their mark on the hydrology of parts of Canada and the U.S .; but termites!? It seems that in southern Africa this industrious insect is responsible for enormous striped patterns of ridges and vegetation bands. These amazingly regular patterns are caused by alternating low ridges and gullies. The ridges are about 2 meters high, up to a kilometer long, and separated by about 50 meters. The ridges themselves are closely spaced termite mounds. Just why the termites choose to build their mounds in long rows is an unanswered question. And how do the termites maintain strict parallelism, especially since they are blind? How could termites in one mound know how their neighbors in the nearest ridge, 50 meters away, are building their mounds? Anyway, the ridges help channel the flow of water and thus the growth of vegetation, giving immense swathes of country a corrugated appearance.

"A large number of anomalous landforms on Mars can be attributed to glaciation, including the action of ice and meltwater. Glacial landscapes are concentrated south of lat -33 and in the Northern Plains suggesting vast Austral and Boreal ice sheets. Crater densities on the glaciated terrains indicate that the final glacial epoch occurred late in Martian history. Thus, Mars may have had a relatively warm, moist climate and dense atmosphere much later than previously believed."

Barnard was one of the great American telescopic observers. J.E . Mellish was an amateur astronomer and a protege of Barnard. Both men may have seen Martian craters; Barnard at Lick Observatory in the early 1890s, and Mellish at Yerkes in 1915. These early dates are what make this story interesting, because prior to the Mariner-4 flyby of Mars in 1965, anyone claiming to have seen craters on Mars would have been labeled a crackpot. Just a mere three decades ago, planetary catastrophism was a ridiculous notion. Barnard never dared publish his drawings of Martian craters for fear of ruining his reputation. Mellish was not so reticent. He wrote and lectured widely on his anomalous observations. No one believed him because his observaconflicted with reigning paradigms. Once the paradigm shifted and craters on other planets were legitimized, astronomers looked back and wondered if Barnard and Mellish really did see craters.

Later analyses of census records indicated that the situation was not quite as bad as Gompertz had supposed. Nevertheless, the death rate does increase with age; but we might be able to do something about it. Immortality might be achievable -- if we take recent medfly studies seriously. "Growing old does not increase your immediate risk of dying -- at least, if you are a fruit fly. The chances of a Mediterranean fruit fly ( Ceratitis capitata ) dying on a particular day reaches a peak and then declines, according to James Carey of the University of California at Davis and James Vaupel of Duke University, North Carolina, and Odense University in Denmark. Their results contradict the notion that the death rate rises with age in all species." The upshot is that there may be no genetic limit to an individual medfly's lifetime.

Brune, you won't find PBRs within 10 miles of spots where quakes have shaken the ground over the past few thousand years. To illustrate: "Rocks stacked in piles and balanced on their narrow ends on Yucca Mountain near the Nevada border with California, he said, have not moved in at least 10,000 years and perhaps as many as 100,000 years, judging from the depth of "rock varnish," or weathering, on their exposed surfaces." Looking for PBRs is not really as useless as it sounds, for they are indicators of stability to construction engineers planning nuclear waste disposal sites and similar projects requiring long-term seismic quiet. (Petit, Charles; "Seismologist Studies Precariously Balanced Rocks," San Francisco Chronicle, December 8, 1992. Cr. J. Covey) Comment. How do rocks become "precariously balanced" in the first place? Melting glaciers and snow packs are known to ease their cargos of rocky debris gently down into unstable configurations. From Science Frontiers #86, MAR-APR 1993 . 1993-2000 William R. Corliss ...

Some wondered if perhaps the Soviets were conducting tests of some new type of weapon in these remote locations. With the end of the Cold War, flights of instrumented aircraft over the islands were permitted. Data from these flights support the idea that the mystery cloud plumes are formed by air currents passing over the islands. In other words, they are only orographic or mountaincaused clouds, like those sometimes seen over the Rockies. But puzzles persist: Why are the plumes so long? Why do they form at such high altitudes -- more than 3 kilometers above the tops of the relatively small mountains on the islands?

One of the most bizarre is the use of hypnosis to raise skin temperature on selected parts of the body. A recently published example of this phenomenon was observed by P. Hajek et al, at the Institute of Physiology in Prague: "Eight patients with atopic eczema and six healthy subjects were given hypnotic suggestion to feel pain in the upper part of the back and in one case on the palm. An average local increase in skin temperature of 0.6 C (detected by thermovision) occurred under this condition. For some patients, cutaneous pain threshold was increased before the experiment by means of repetitive hypnotic suggestion of analgesia. These subjects reported feeling no pain subjectively, but the local change in skin temperature was equal in both cases. The results suggest a central mechanism induced by measuring changes in pain threshold in the skin, which changes are independent of local changes in blood flow."

These are 3 (three evens), 4 (four odds), and 7 (seven is the total number of digits), respectively. Use these digits to form the next string or number, 347. If you repeat the process with 347, you get 1, 2, 3. If you repeat with 123, you get 123 again. The number 123, with respect to this process and universe of numbers, is a mathematical black hole." We have a black hole because we cannot escape, just as spaceships are doomed when captured by a physical black hole! You end up with 123 regardless of the number you start with. Other sorts of mathematical black holes exist, such as the Collatz Conjecture, but we must not fall into them because our printer awaits.

Zinsmeister was accustomed to scoff at the idea that the Age of Dinosaurs ended violently with the impact of a giant asteroid some 65 million years ago. He always asked: "Where's the layer of burnt and twisted dinosaur bones?" His certainty was shaken, however, when he began mapping fossil deposits on Seymour Island, Antarctica. He didn't find the dinosaur bones but rather a giant bed of fish bones at least 50 square kilometers in area. Some sort of catastrophe must have annihilated untold millions of fish. And guess what? This great bone bed was deposited directly on top of that layer of extraterrestrial iridium that marks the 65-million-year-old Cretaceous Tertiary boundary at many sites around the world. (Hecht, Jeff; "The Island Where the Fish Had Their Chips," New Scientist, p. 16, November 11, 1995) Cross reference.

Basketball may now be added to this file, according to a recent paper by E.H . Schreiber: "Throughout one basketball season 12 male and 12 female basketball players were interviewed prior to individual and group sessions with hypnosis. The athlete's shooting scores were compared with those of the previous basketball season. The hypnosis groups showed higher cumulative scores for shooting than players in the control group."

The scene is a Norwich, England, garden, wherein one night a plastic saucer full of tap water was placed. The night was clear, cold, and windless. In the morning, T. Bushnell found protruding from the saucer a "strange tubelike structure" about 3 inches long. His color photograph cannot be conveniently reproduced here, but it clearly shows his icicle growing upward at about a 45 angle. Bushnell wrote further: "What may not be apparent from the picture is that the tube is triangular in cross section and it is completely hollow down as far as the unfrozen water lying underneath the thick layer of ice. The fairly robust tube was an integral part of the underlying ice pool. We noticed that the outside of the tube was segmented in appearance, as though the ice had built up layer by layer." (Bushnell, T.; "Ice Surprise," New Scientist, inside back cover, October 7, 1995) Comment. The other "weird" icicles we have reported were all solid and roughly hexagonal prisms.
