Duesberg, who holds that the so-called AIDS virus, HIV, is not the sole cause of AIDS. Echoing many of Duesberg's assertions is biochemist and immunologist R.S . Root-Bernstein. He points out that: "People all over the world are getting AIDS without being exposed to or infected with HIV." Root-Bernstein continues with: "The implications of this revelation are truly astounding. Essentially there are only three possibilities. The HIV may really be there, but everyone has missed it. This is un-likely, since many of the researchers reporting HIV-negative cases of AIDS are the top HIV experts in the world. Another possibility is that there is a new virus that everyone has missed. This is again unlikely given the huge amount of retroviral research that has been performed in the past decade on AIDS patients. Finally, these may be the cases that demonstrate that AIDS can be produced by the types of synergistic, multifactorial assaults on the immune system that Joseph Sonnabend and I have been proposing for years." Although most AIDS researchers are still wedded to the theory that HIV is the sole and only cause of AIDS, cracks in the stonewalling are beginning to appear. In fact, C.A . Thomas, Jr., formerly a Professor of Biochemistry at Harvard, has organized the Group ...

The authors went back in history and examined a host of documents from the Middle Ages -- the lives of saints, histories, biographies, etc. They identified visionary experiences and explored the biological and sociological contexts. Kroll and Bachrach found 134 visions; that is, experiences that had no objective reality. We call such experiences hallucinations today; and their contents were the same then as they are now. What the authors are after in this study are the perceptions of the visionary experiences by the community. The survey demonstrated immediately that the visions of the Middle Ages appeared to all types of people, not just saints and seers; and, further, that most of the 134 experiences were unrelated to physical and mental health. It was also obvious that the various communities readily accepted these visions as bona fide spiritual and parapsychological experiences. In other words, they were taken as messages from God, predictions of future events, marks of spiritual favor, etc. Kroll and Bachrach concluded that in the Middle Ages visions were culturally supported phenomena and not evidences of psychological illness, as they are today.

Meaden's "middle-ground" position on the now-infamous crop circles, we stated that an earlier letter to Weather by J.W . Deardorff represented the "all-hoax" position. This was incorrect and, to be fair, we now reproduce Deardorff's letter: "Recent letters to Weather indicate little agreement concerning the crop circles mystery, except that the phenomenon is in general no hoax. Lest it be thought that Dave and Doug made them all, including over 1000 in the season of 1990 and as many as 15 in one night, consider the following crop circle streamline configurations: an upper layer, with an inward directed swirl of stems as viewed from above, and underneath a lower layer swirled outwards and orthogonal to the upper layer. This was the situation for the 17 m circle discovered by Busty Taylor at Headbourne Worthy, which appeared overnight on 1 August 1986 (Delgado and Andrews 1989). Its stem "streamlines" were sketched by Meaden and Andrews (Noyes 1990). Somehow the source-mechanism of this circle apparently first swirled every other stem outwards while leaving the remaining stems standing, then swirled the remaining stems inwards and at right angles to the layer below, again without any appreciable breakage of crop stems.

He does not dispute that humans may also have evolved in Africa and, perhaps, Southeast Asia. And he has brought back some 4,000 stone tools collected at 15 sites in the Siberian permafrost to bolster his claim that Siberia, too, was a point of origin for hominids (see map). "Molchanov's controversial evidence is indeed striking: a collection of chipped and flaked rocks that are clearly artifacts fashioned by humanlike hands and that he contends are 2.5 million years old -- plus or minus a half-million years. "Remarkably, that same era marked the time when early human ancestors known as Homo habilis lived and left their remains in the tropical Olduvai Gorge of what is now Tanzania. Mochanov's collection of tools closely resembles the ones that anthropologists have long collected from digs in Africa." All this contrasts strongly with the dominant view of hominid evolution, which cites warm, verdant African forests and savannas as our most likely place of origin. Siberia, with its -50 winters and fleeting summers, hardly seems conducive to hominid speciation. Mochanov's rationale is that this severe climate actually stimulated ancient hominids to create tools, fashion warm clothing, and build winter shelters -- these Siberian hominids had to evolve or perish! In addition to the climate factor are two other problems: (1 ) The ...

The effect is sometimes quite dramatic. There are accounts of a 'low roar' as the bands of breaking waves, 'walls of white water,' pass a vessel. The bands are sometimes visible from aircraft, on ships' radar and are observed from satellites. In the Bay of Biscay 'boils' have been reported on the sea surface in the calm zones, and appear to be related to pulses of nutrients from the thermocline." These surface phenomena are truly delightful and almost always the consequence of internal waves interacting with the surface. The great bulk of the referenced report is concerned with sonar observations of internal waves and their effects along the coast of Scotland.

This is one reason why cold fusion got the cold shoulder from most physicists. Now for the "however" that is the hallmark of Science Frontiers : "Thirty years ago, Otto Reifenschweiler was searching for a compound which could protect Geiger-Mueller tubes from damage when they are first ionised. He found the compound, which became a money-spinner for Philips, in a mixture of titanium and radioactive tritium. He also discovered that as the mixture was heated, its radioactivity declined sharply. No process known to physics could account for such a baffling phenomenon: radioactivity should be unaffected by heat. Nevertheless, as the temperature increased from 115 C to 160 C, the emission of beta particles fell by 28%." Reifenschweiler and his colleague, H. Casimir, put this discovery on the backburner and concentrated on the Geiger-Mueller tubes. The recent furor over cold fusion impelled them to resurrect the work and publish it in the January 3 issue of Physics Letters A . Is there a new phenomenon here? Is it relevant to cold fusion? It may be pertinent that some common fusion reactions also employ tritium. (Bown, William; "Ancient Experiment Turns Heat Up on Cold Fusion," New Scientist, p. 16, January 8, 1994.) Comment.

But here follows the abstract from a recent paper printed in a European journal. It presents data that could lead to a technique for separating "real" crop circles from hoaxes! "Crop formations consist of geometrically organized regions ranging from 2 to 80 m diameter, in which the plants (primarily grain crops) are flattened in a horizontal position. Plants from crop formations display anatomical alterations which cannot be accounted for by assuming the formations are hoaxes. Near the soil surface the curved stems often form complex swirls with 'vortex' type patterns. In the present paper, evidence is presented which indicates that structural and cellular alterations take place in plants exposed within the confines of the 'circle' type formations, differences which were determined to be statistically significant when compared with control plants taken outside the formation. These transformations were manifested at the macroscopic level as abnormal nodal swelling, gross malformations during embryogenesis, and charred epidermal tissue. Significant changes in seed germination and development were found, and at the microscopic level differences were observed in cell wall pit structures. Affected plants also have characteristics suggesting the involvement of transient high temperatures."

At 5:11 A.M ., crews of three trawlers at widely separated sites off south Greenland reported "a blazing fireball that turned night into day." At a distance of 100 kilometers (62 miles), the flash was compared to that from an atmospheric nuclear explosion. Danish officials dismissed the possibility of a surreptitious nuclear test. The U.S . Air Force stated that the object was neither a reentering spacecraft nor artificial space debris. Some seismic tremors also emanated from Greenland, so the impact of a large meteorite is suspected. Based on the visual sightings and a moving object caught on a parkinglot surveillance camera in Nuuk, Greenland's capital, the probable impact point is at 61 25' N., 44 26' W. Efforts to locate the meteorite will have to wait for favorable weather. The supposed meteor was not a small object. The Niels Bohr Institute in Copenhagen compared it to the Kap York meteor that fell south of Thule, Greenland, in prehistoric times.

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." ( ...

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."

The subject matter is irresistible and, to make things more interesting, New Scientist has published a scathing review of it, castigating Hoyle for his doubts about evolution and terming his approach "dispicable." (My! How conventional people hate unconventional people!) In this new book, Hoyle goes far beyond his previous thesis, which in essence declared that from statistical considerations life could not have arisen and evolved on earth. Rather, life had to come from outer space, probably in the form of bacteria and viruses. Evolution was and is dependent upon new information arriving from outer space on tiny bits of life. Hoyle now greatly extends his theory: "But where did a knowledge of amino acid chains of enzymes come from? To use a geological analogy, the knowledge came from the cosmological equivalent of a previous era, from a previously existing creature if you like, a creature that was not carbon-based, one that was permitted by an environment that existed long ago. So information is handed on in a Universe where the lower symmetries of physics -- and characteristics of particles and atoms -- are slowly changing, forcing the manner of storage of the information to change also in such a way as to match the physics.

This idealistic picture is changing because several lines of evidence suggest that some plates are separated by miles of geological "mush." J-Y . Royer and R.G . Gordon came to this conclusion after careful inspection of the huge Indo-Australian plate. First, they noticed that many powerful earthquakes originated in the center of this plate. Usually, quakes are confined to the edges of plates where they crunch against neighboring plates. Second, a line of folds 3,000 feet high runs down the center of the plate, as if is being squeezed like an accordion. But they could not identify any geological accordionist. Finally, working backwards in time using paleomagnetic data, they reconstructed plate configurations 11 million years ago. The Indo-Australian plate did not match up with its neighbors of that time period. Royer and Gordon concluded that the Indo-Australian plate really consists of three smaller plates. Even more surprising was their discovery that in between the boundaries of the three new plates there is a tectonic morass perhaps a thousand miles wide in places -- the "miles of mush" of our title. Plate tectonics (nee "continental drift"), once a revolutionary idea in geology and geophysics, seems poised for another upheaval. (Anonymous; "Gaps in the Theory," Earth , 7:11 ...

Per-haps there is a clue in the following correlation: "The Mesozoic-Cenozoic histories of reversals in the earth's magnetic field and of periods of widespread anoxia in the ocean basins show a remarkable correlation; periods of black-shale deposition (' anoxic events') occur during lengthy periods without magnetic reversals (' quiet periods'). My assembly of published work indicates a remote connection between quiet periods and anoxic events and suggests its form: Magnetic quiet periods coincide with fast seafloor spreading. During these periods, buoyant spreading ridges displace seawater into broad shelves, thus decreasing earth's albedo and causing global warming. Temperature gradients, and thus density gradients, from pole to equator decrease in surface waters, and the deep ocean currents of oxygenated polar waters wane. Oxygen minimum zones intensify and widen; anoxic conditions throughout entire basins are indicated by black shales deposited in the deep sea. These relations thus suggest that the earth's interior processes and its climates are related and their status recorded by both magnetic polarity and anoxic event chronologies of the earth."

First, they point to the steady drizzle of tiny, organic-rich particles drifting down to earth from cometary debris. These particles, which even carry spacesynthesized amino acids down to the earth's surface, seem likely chemical precursors of life. However, the atmosphere is also a potential source of prebiotic chemicals -- providing energy sources are available. Chyba and Sagan suggest as sources: lightning, ultraviolet radiation, and the shock energy derived from meteorite/asteroid/comet impacts. Together these energy sources, especially ultraviolet light, might synthesize thousands of tons of complex organic compounds each year.

Billions of stars are nothing to them. The megaparsec (3 ,528,000 light years) is but a hop, skip, and jump. A pressing question for these cosmologists searching for the really big picture is whether there is any order in the distribution of galaxies, galactic clusters, and superclusters. The scale of organization of the universe is of critical importance because it is a measure of state of the cosmos when hydrogen atoms first condensed from the seething sea of ions following the Big Bang. The prevailing expectation has been that galactic clusters and superclusters should be distributed at random; that is, no order prevails at that scale. Recent redshift measurements, however, hint more and more forcefully that the huge superclusters of galaxies are almost as neatly arranged as the atoms in a crystal. A recent paper in Nature by J. Einasto et al puts a number on the spacing of the superclusters: "Here, using a new compilation of available data on galaxy clusters, we present evidence for a quasi-regular three-dimensional network of rich superclusters and voids, with the regions of high density separated by "120 Mpc [megaparsecs]. If this reflects the distribution of all matter (luminous and dark), then there must exist some hitherto unknown process that produces regular structure on large scales."

Some of these boulders weigh more than a ton. In some places, the walls reach five feet in height and three feet in width. They extend for miles along the hill crests from Berkeley to Milpitas and beyond. Russell Swanson, one of the few persons willing to pursue the walls in the field, estimates that all the walls strung together would run for at least 20 miles. Naturally, time and civilization have destroyed some of the walls, but what remains is most impressive. The searches of property records going back to the Gold Rush and the studies of Spanish mission records give no hints of who built the walls or why. Evidently they are centuries old, possibly prehistoric. Why would anyone build miles of walls from ponderous boulders along miles of ridge crests? They appear to serve no practical purpose. Scientists seem to show no interest in the walls. One even stated: "I don't know of anyone who's come up with a credible explanation.

Heckman, of the University of Maryland, has ordained that the apostles of noncosmological redshifts must now recant. He and his colleagues believe that they now have the most convincing demonstration to date that quasar redshifts are of cosmological origin; that is, the larger the redshift, the faster the quasar is receding and the farther away it is. "Availing themselves of the extraordinary new imaging and spectroscopic capabilities of charge-coupled-device (CCD) detectors, they have measured the redshifts of 19 nebulous objects that appear to be companion galaxies of 15 relatively low-redshift quasars. Observing at the Kitt Peak 4-meter telescope, they have determined that, in 18 of these 19 cases, the apparent companion has a redshift very close to that of the quasar. While Burbidge, Arp and their partisans may argue that quasars are so peculiar that they can generate redshifts of unknown origin, this position becomes difficult to maintain for companion galaxies that otherwise look perfectly ordinary." H. Arp and G. Burbidge, chief among those ordered to recant, are not convinced. Arp points to many cases where bridges of luminous material connect high-redshift quasars with low redshift galaxies. Also, the clustering of quasars around nearby galaxies supports the nearness of quasars. As Burbidge has observed, if: ". .. just one large redshift is not due ...

Like Evolution and Relativity, the Big Bang is usually paraded as a proven, undeniable fact. It isn't . Static-universe models fit the data better than expanding-universe models. The microwave "background" makes more sense as the limiting temperature of space heated by starlight than as the remnant of a fireball. Element-abundance predictions using the Big Bang require too many adjustable parameters to make them work. The universe has too much largescale structure (interspersed "walls" and voids) to form in a time as short as 10-20 billion years. The average luminosity of quasars must decrease in just the right way so that their mean apparent brightness is the same at all redshifts, which is exceedingly unlikely. The ages of globular clusters appear older than the universe. The local streaming motions of galaxies are too high for a finite universe that is supposed to be everywhere uniform. Invisible dark matter of an unknown but non-baryonic nature must be the dominant ingredient of the entire universe. The most distant galaxies in the Hubble Deep Field show insufficient evidence of evolution, with some of them apparently having higher redshifts (z = 6-7 ) than ...

Kirschvink, of the California Institute of Technology, has plotted the hundreds of beachings of whales and dolphins along the U.S . east coast. He finds that these cetaceans tend to run aground at spots where the earth's magnetic field is diminished by the local magnetic fields of rocks. These coastal magnetic lows are at the ends of long, continuous channels of magnetic minima that run for great distances along the ocean floors. Kirschvink believes that the stranded whales and dolphins were using these magnetic troughs for navigation and failed to see the stop sign at the beaches and ran aground. The mag-netic troughs in this view are superhighways for animals equipped with a magnetic sense. If Kirschvink's theory is correct, the magnetic sensors of the whales and dolphins are extremely sensitive, because the deepest magnetic troughs are only about 4% weaker than the background magnetic field. Magnetite crystals have been found in birds, fish, and insects, where they are thought to contribute to a magnetic sense of some sort. So far, no magnetite has shown up in whales and dolphins.

First, we quote the summary from a recent Persinger paper. The jargon may be technical, but one can readily visualize the human brain immersed in a sea of signals -- nominally electromagnetic but possibly of other sorts. "Contemporary neuroscience suggests the existence of fundamental algorithms by which all sensory transduction is translated into an intrinsic, brain-specific code.

The circumstances under which previous expeditions had obtained sonar and photographic evidence in support of the existence of the Loch Ness monster could not withstand scrutiny.

Archeologists have debated the mound's purpose for decades. Being elevated above the floor of a usually dry canyon as it is, the mound certainly does not seem to be a reservoir, but that is what recent research says it is. The mound is shaped like an inverted frying pan, with a 1500-foot-long handle that leads to a normally dry stream bed higher up in the canyon. The Anasazi were excellent water managers and took advantage of the flash floods that roared down the canyon every few years. To impound some of this valuable water, they initially built a conventional reservoir, but it was soon silted up by the freshets. So, they gradually raised the reservoir walls and constructed a raised canal to the stream bed. It was all very logical. The engineering of the canal is particularly impressive. The channel is 4-8 feet wide, but only 1-2 feet deep. Its steep, 15-foot-high sides are shored up with neatly aligned stones that were carried in from somewhere outside the canyon.

The sonic boom came several minutes later -- but the swishing sound occurred simultaneously with the visual apparition....Ben graphically described the sounds as 'like a skier coming down a slope,' but with a rapid fluctuation in loudness, 'about two or three hertz.' Jeannette compared the faint sound to the noise made by a fast boat as it slaps across waves on a choppy lake.

Within its "walls" they found a piece of burnt bear bone that was later carbondated as at least 47,600 years old. A burnt bone and a geometrical structure certainly suggest the work of an intelligent creature, as does the site's great distance from the surface. Torches would have been a necessity that far in. That 47,600-year figure, though, presents a problem. The first Cro-Magnons didn't filter into western Europe until about 35,000 BP. According to the accepted anthropological schedule, only those subhuman Neandertals inhabited that part of France in 47,600 BP. So, we must conclude that the Neandertals knew well the sophisticated use of fire. They also had enough curiosity to venture deep into the earth, where for some unknown purpose they piled together an enigmatic structure.

Surprisingly, two articles on snowflake anomalies have appeared recently. To form at all above -40 F, snowflakes supposedly require a solid seed or nucleus around which ice can crystallize -- or so scientists have assumed for many years. It was long believed that airborne dust, perhaps augmented by extraterrestrial micrometeoroids, served as the necessary nuclei. But cloud studies prove that there are about a thousand times more ice crystals than dust nuclei. Now, some are convinced that bacteria blown off plants and flung into the air by ocean waves are the true nuclei of atmospheric ice crystals. Remember this the next time you tast a handful of snow! (Carey, John; "Crystallizing the Truth," National Wildlife, 23:43, December/ January 1985.) Comment. The possibility that the fall of snow and all other forms of precipitation is largely dependent upon bacter-ia brings to mind the Gaia Hypothesis; that is, all life forms work in unison to further the goals of life. The second item is from Nature and is naturally more technical.

The doses were administered: (1 ) openly, when the experimenter knew which substance was being given; (2 ) by a person hidden from both experimenter and patient; and (3 ) by a machine.

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.

Instead, earth-based astronomers watch for occultations or dimmings of stars as they pass behind the rings. This seems straightforward enough in theory, but the occultations have been perplexing in practice. First, one member of a closely spaced double star will be occulted normally by the rings but its companion won't . Second, some terrestrial observatories will record an occultation but another a few thousand miles away will not. Such experiences have led to the hypothesis that the rings are discontinuous; that is, they are arcs rather than complete rings. Why should Neptune's rings be different from those of the other major planets? On speculation maintains that the arcs are the consequence of one or more recently satellites. Another hypothesis, by J.J .

However, the heart of the comet, its nucleus, has long been considered a "dirty snowball"; that is, a mixture of dirt and ices. Now it appears that comets are more like "icy dirtballs"! And some of that dirt is pitch black. New measurments of the bare nuclei of comets, using a visual-infrared technique, find that the nuclei reflect as little as 2% of the incident sunlight. They are indeed charcoal black. Comet nuclei, according to W. Hartmann and his colleagues, are colored by a brownishblack primordial organic sludge, and have the appearance of "a very dark Hershey bar." The use of the adjective "organic" may be premature, but in light of the next item, maybe not. (2 ) Carbonaceous chondrites . This well-known class of meteorites sometimes appears tarry and is characterized by carbon contents ...

After lengthy cooling periods, the crystalized diamonds were transported to the surface by fluid, lower-melting-point rocks, such as kimberlite. Many South African diamonds are mined from kimberlite pipes. Diamonds are never pure carbon; they always contain some nitrogen and boron. Occasionally, they harbor tiny radioactive impurities; usually alpha-particle emitters in the uranium-238 decay chain. Alphas emitted by these impurities have well-defined energies and penetrate the diamond matrix only so far. If one examines a diamond with a high-power microscope (say, at 100 x), one can see concentric rings surrounding the impurities. These dark radiohalos or "pleochroic" halos have specific radii and can be used to identify the radioisotopes that produced them. So far, so good; but: "The fact that fully formed, optically visible internal radiohalos in diamonds are now presented casts a considerable shadow over current theories of diamond genesis." Actually, the radiohalos pose three challenges to diamond-genesis theory. Problem 1. The half-lives of the halo-creating radioisotopes are measured in thousands of years rather than the billions prescribed for crystallization. ...

Leave comfortable earth for a moment and consider the immense, cold clouds of gas and dust swirling between the stars and galaxies. At near-absolute-zero, sunless and waterless, these clouds hardly seem the womb of life. Yet, there may be found the atoms necessary to life -- H, C, O, N, etc -- and in profusion. Collisions of cosmic rays can promote the synthesis of fairly large molecules. We have already detected molecules as complex as formaldehyde in the interstellar medium. But surely the immensely more complicated molecules of biology cannot be synthesized near absolute zero. This may not be true either because at extremely low temperatures the quantum mechanical phenomenon of "tunnelling" becomes important. To achieve molecular synthesis, repulsive barriers must be overcome. The warm temperatures in that terrestrial pond can provide the extra kinetic energy to climb over these barriers. In cold molecular clouds we must look elsewhere. The laws of quantum mechanics state that there is always a very low probability that atoms and molecules can tunnel through repulsive barriers -- no need to climb over them via thermal effects. "Specifically, entire atoms can tunnel through barriers represented by the repulsive forces of other atoms and form complex molecules even though the atoms do not have the energy required by classical chemistry to overcome ...

The story broke last September (1996), in Sydney, Australia, and has been simmering ever since. We have let the story cook for a while, hoping to get some confirmation of the dates involved. This will have to come later. These "circles of contention" are engraved on tall boulders (about 2 meters high on average) arranged in arcs hundreds of meters long at a site the aborigines call Jinmium. Jinmium is located near the western boundary of Australia's Northern Territory. The circles are obviously the work of humans. There are thousands of these etchings all told. Dimensions: 2-3 centimeters across and about half as deep. No one doubts that the Jinmium site is ancient. Judging from the sediments that cover the lowest circles, these engravings are about 60,000 years old. If this date survives scrutiny, the Jinmium carvings will be the oldest human art on the planet -- twice as old as anything found in Europe. No wonder the circles have created a stir. Actually, though, a larger issue is at stake. In the sediments around the engraved boulders, anthropologists have discovered what seem to be even-more-ancient signs of human activity: stone tools stratigraphically dated at 116,000 and 176,000 years.

Secular humanists hate astrology with a passion because, like Cassius in Julius Caesar, they believe we are masters of our own destinies. Nevertheless, astrol-ogy columns are still prominent in most newspapers. In the scientific press, however, we have to score a big plus for the anti-astrologers. First, Nature has just published a detailed analysis of the predictive power of astrology, and astrology has come up very short. The Nature study is by S. Carlson, a physicist at the University of California at Berkeley. At the end of seven data-packed pages Carlson concludes: "We are now in a position to argue a surprisingly strong case against natal astrology as practised by reputable astrologers. Great pains were taken to insure that the experiment was unbiased and to make sure that astrology was given every reasonable chance to succeed. It failed. Despite the fact that we worked with some of the best astrologers in the country, recommended by the advising astrologers for their expertise in astrology and their ability to use CPI (California Personality Inventory), despite the fact that every reasonable suggestion made by the advising astrologers was worked into the experiment, despite the fact that the astrologers approved the design and predicted 50 per cent as the 'minimum' effect they would ...

Briefly, this "fallacy" states that a single type of discrepant observation should not be considered viable if it contradicts a large body of well-established, internally consistent observations. In geology, the Residue Fallacy is employed to dismiss the precursorless polonium halos found by R.V . Gentry, as well as some other radiometric discordances. These scientists seem to have forgotten about the anomalous advance of Mercury's perihelion and a few other obvious residues that ultimately stirred up revolutions in our thinking. Anyway, it is now satisfying to find the Editor of Nature, mainstream science's preeminent journal, acknowledging the value of anomalies. The stimulus in this case is the morethan-a -decade-old inability of astronomers and physicists to explain the missing solar neutrinos. Two new, more sophisticated, neutrino detectors have come on line, in Japan and the U.S ., and they have confirmed the results obtained in the huge vat of cleaning fluid in the Homestead Mine, in South Dakota. For some reason, everyone measures only about one-third the number of solar neutrinos expected. Either something is wrong with our model of the sun's (and other star's ) energy-producing mechanism or our ...

The authors of this article stess the pitfalls of using data handed down verbally from generation to generation. With these caveats, they reproduce an Indian tradition originally set down by Judge James Swan back in 1888: "' A long time ago,' said my informant, 'but not at a very remote period, the water of the Pacific flowed through what is now the swamp and prairie between Waatch village and Neeah Bay, making an island of Cape Flattery. The water suddenly receded leaving Neeah Bay perfectly dry. It was four days reaching the lowest ebb, and then rose again without any waves or breakers, till it had submerged the Cape, and in fact the whole country, excepting the tops of the mountains at Clyoquot. The water on its rise became very warm, and as it came up to the houses, those who had canoes put their effects into them, and floated off with the current, which set very strongly to the north.'" The authors of the present article wonder if the above could be an account of a massive tsunami! They admit that the 4-day recession is inconsistent with tsunami action and that the warm water is hard-to-explain. The height reached by the inundation -- some 400 meters -- is also incredible.

Equatorial Eastern Atlantic. "Whilst the vessel was approaching the equator, on a course of 023 and at a speed of 10.3 knots, flashing white lights were observed. The sea was rippled, with a low NW'ly swell and the wind light airs. The visibility was good, with the moon in its first quarter. At first it was thought that there were three lights, one being bright and the other two relatively dim, but as the vessel approached it it was decided that there were only two, one bright and one dim. "The radar, a 10-cm S-band Decca, was switched on and a single echo was detected initially at a range of 5 n. mile. By this time the lights had already been observed for halfan-hour, so it was estimated that they had first been observed when they were 10 n. mile distant. The time of the first sighting was 2220 GMT. The target, once detected, gave a very strong echo and gave the impression of being a large target. It was plotted and found to be stationary. The initial course of 023 was altered to 028 in order to enable the vessel to close the passing distance. "Throughout the observations neither light followed any set characteristic. Instead they just flashed at random, but never together. The intensity of the bright light would have ...

Humans with cortical blindness; that is, they have lost their primary visual cortex through brain damage or disease; can still detect objects and yet be unaware of them. Doesn't sound right, does it? The situation is this: A person, apparently totally blind, can somehow discern the location, form, and size of objects, but they will swear that they "see" nothing at all. In fact, they are blind by all tests. They have blindsight. One explanation of blindsight maintains that the visual cortex has not been totally destroyed, and that functional remnants remain. In scientific terms, blindsight represents "suboptimal functioning of the primary visual cortex." But now, A. Cowey and P. Stoerig report that they have totally removed the primary visual cortex from monkeys' brains. (Something one would not try with humans!) Tests with the visual cortex-less monkeys demonstrated that they possessed blindsight. Therefore, blindsight does not seem to be "suboptimal functioning" of a damaged brain -- at least in monkeys. Blindsight thus remains a mysterious biological function. How do blindsighted humans detect objects of which they are not visually aware? Somehow information about the visual world appears in the brain. (Cowey, Alan, and Stoerig, Petra; "Blindsight in Monkeys," Nature, 373: 247, 1995. Also ...
