At present, over 120 hotspots are recognized by geophysicists -- and they are not distributed randomly about the globe. In fact, many seem to be diametrically opposite one another, as described by M.R . Rampino: "The observed number of antipodal hotspot pairs depends on the maximum allowable deviation from exact antipodality, At a maximum deviation of 700 km, 26% to 37% of hotspots form antipodal pairs in the published lists examined here, significantly more than would be expected from the general hotspot distribution. Two possible mechanisms that might create such a distribution include: (1 ) symmetry in the generation of mantle plumes; and (2 ) melting related to antipodal focusing of seismic energy from large-body impacts."

'It's a loud and audible mechanical raspy hum,' said Waldo Point Harbormaster Ted Rose, who said the vexing noise sounded like an electric razor. 'It sounds like this mzmzmzmzmzmzmzm,' Rose said. 'Sometimes it gets so loud you have to talk above it. It can drown out conversations and wake people from a dead sleep.' For reasons no one understands, the noise can be heard only from about 8 p.m . until sunrise, and it goes silent from late September until mid-April, when it begins humming again through the summer." Acoustical engineers from Berkeley could not pinpoint the source of the sound with the help of instruments and a diver. Biologists believe the noise is made by the singing toad-fish, also called the plainfin midshipman. (Leery, Kevin, "Sausalito's Weird Hum Is Back, " San Francisco Chronicle, July 29, 1985. Cr. P.

We have space for only two in this issue of SF. In the first of these, Barry Fell deals with the criticism that the now-famous Los Lunas (New Mexico) inscription cannot be the work of ancient Hebrew-writing visitors to the New World because it employs modern punctuation marks. Fell counters this by reproducing several ancient texts that use similar punctuation conventions, thus blunting this attack on the antiquity of the Los Lunas inscription. For readers unacquainted with the Los Lunas inscription, it consists of the Decalogue (the Ten Commandments) engraved in ancient Hebrew on a large basalt rock near Los Lunas, NM. In the second paper, geologist G.E . Morehouse comes to grip with a second criticism leveled at the inscription; namely, that the engraving looks fresh and lacks the patination characteristic of great age. Morehouse concludes that the freshness actually derives from the frequent, recent scrubbing of the inscription (with wire brushes on some occasions) to improve its visibility. Taking this into account, Morehouse estimates the age of the Los Lunas inscription by comparing its weathering with a nearby 1930 inscription. Conclusion: the Los Lunas inscription is much older than 1930. Any length of time from 500-2000 years or ...

From force of habit, he scanned the woods, his spotlight punching through black walls of rain. And there in the beam was one of the strangest creatures he had ever seen. About the size and shape of a dog, it was covered with stripes that ran from its shoulders across its back to its thick, rigid, tail. "The animal stood still as the startled ranger counted the stripes, then it nonchalantly gave an enormous jaw-stretching yawn. But when the ranger reached for his camera, the creature faded into the undergrowth, leaving nothing but a rank smell. It also left a trail of excitement, for the bizarre beast looked exactly like a Tasmanian tiger -- also called a thylacine or Tasmanian wolf -- an animal thought to have been extinct nearly 50 years ago." Hundreds of people claim they have spotted the Tasmanian tiger since the last captive died in 1936, but we have no good photos or other "proofs." Mediaman Ted Turner has offered a prize of $100,000 for "verifiable evidence" that the Tasmanian tiger still lives.

If one does not count the rather primitive notion of Air, Fire, Earth, and Water, there are five basic levels of compositeness: (1 ) molecules; (2 ) atoms; (3 ) nuclei; (4 ) nucleons; and (5 ) quarks and leptons. But now physicists are beginning to see regularities in the lowest accepted layer, quarks and leptons, that betoken a sixth layer of compositeness or subdivisibility. In other words, quarks and leptons are not really fundamental and instead are composed of something else, which will undoubtedly eventually receive fanciful names. In this article, O.W . Greenberg delves into this sixth stratum and the "regularities" it engenders.

To acquire raw material, he scraped skin cells from the insides of casts discarded by skiiers who had had broken bones. From this debris, Berliner extracted numerous chemical compounds. As far as anyone could tell, these substances were odorless, so he stored them in open flasks. However, Berliner noticed that when people were working in the lab with the flasks, they were more friendly and relaxed than normal. He could not divine the reason until some months later when he decided to cover the flasks of skin-derived substances. Curiously, the lab workers soon reverted to their usual grumpy selves! What could account for this strange behavior change? Knowing that animals often communicated with one another employing chemicals called pheromones, Berliner suspected that the flasks had been releasing odorless human pheromones. Sure enough, analysis of the skin-derived materials proved him correct. Next: A Look Up the Nose. Biologists have long realized that animal noses actually contain two sensory channels. The first is the familiar olfactory system, which humans also possess. The second channel is the vomeronasal system. In animals, each system has its own separate organs, nerves, and bumps in the brain. The function of the vomeronasal system is pheromone detection.

... profound question is: Why do sea-shells need to be pretty in the first place? After all, most (but not all) of the shell owners do not have eyes with which to appreciate their handiwork! However, mathematicians and computer modellers do have eyes. They have also had a lot of fun and some success in devising algorithms (mathematical methods) for the generation of seashell markings. In fact, our title above is also the title of a new book by H. Meinhardt, which suggests how a suite of simple biochemical processes can create those shells coveted by collectors. Meinhardt has devised equations that describe chemical factors that turn pigment-generating cells on and off. In its simplest form, a mathematically modelled seashell is a two-dimensional sheet that grows along only one edge. Cells on this edge may or may not secrete pigment depending upon chemical "influences." B. Hayes describes how this sort of model operates: The triangular pattern on Cymbiola innexa suggests the presence of a "global control element" that turns the pigment-secreting cells on and off in the correct order -- something like a computer-controlled loom! "Given this generating mechanism, some shell patterns are easy to understand. A series of vertical stripes -- that is, stripes running perpendicular to the growing edge -- implies a static distribution of pigment secreting cells in the mantle margin. Where a cell or group of cells is permanently turned on, there is a dark stripe of pigment, and where the cells are dormant, there is an unpigmented space. ...

Austin, Texas. About 8 PM, during an intense thunderstorm, P. Gunkel heard a whistling sound, like that made by a descending firework rocket. A general pinkish brightening of the surroundings accompanied the sound. Half a second after the sound ceased, there was a tremendous clap of thunder. Discussions with neighbors within 1 hour of the event, elicited additional data: one said that it sounded like rocks falling through the air; another heard a strange humming sound from a windowpane for 2 seconds prior to the lightning; yet another spoke of a sound like that of a whistling tea kettle, but with an ascending pitch; and a fourth actually saw the lightning strike the street about 500 feet away. (Gunkel, Patrick; personal communication, May 13, 1989.) Comment. The most common sound heard prior to nearby lightning strikes is a "vit" sound, or a sound like fabric tearing.

Formerly, the Nauruans led energetic lives -- fishing, subsistence farming -- and they were slim and healthy. Then came colonization and phosphate mining; with these came wealth, imported caloriepacked food, sedentary lives, obesity, and, unhappily for this tropical paradise, diabetes. The incidence of diabetes mellitus shot up to 60%, an astounding statistic by world standards. On one of the wealthiest of the Pacific islands, the inhabitants have the shortest life spans! The same scenario is being played out in other parts of the world where life styles have changed drastically; for example, some Polynesians, American Indians, and Australian aborigines are similarly afflicted. Furthermore, an epi-demic of diabetes mellitus is anticipated as the "benefits" of civilization are brought to India and China. Two questions must be answered: (1 ) Why is the incidence of diabetes mellitus only 8% among American junkfood-eating couch potatoes?

"It is concluded that on five occasions during the interval 20,000-14,000 years BP, cosmic dust mass concentrations in the solar system rose by one and two orders of magnitude above present day levels. Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate. Thus it is quite possible that these dust congestion episodes were responsible for the abrupt climatic variations which occurred toward the end of the last Ice Age."

This synchronism suggests some sort of energy interchange between Io and the top of Jupiter's atmosphere. The theory now in vogue states that Jupiter's rotating magnetic field induces a voltage across 2300-mile-diameter Io, resulting in an electrical current of some 5 million amperes flowing between Io and Jupiter, some 262,000 miles away. In this bizarre electrical circuit, the two moving "terminals" on Jupiter, in the northern and southern hemispheres, are heated by the current flow and show up as fuzzy infrared-bright spots.

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.

"The view that man did not arrive on the American continent before the last glaciation has been supported by the fact that until now the known and dated archaeological sites have not been of very great antiquity. But now we report radiocarbon dates from a Brazilian site which establish that early man was living in South America at least 32,000 years ago. These new findings come from the large painted rock shelter of Boqueirao do Sitio da Pedra Furada, the walls and ceiling of which are decorated with a rich set of prehistoric paintings. We have excavated a sequence containing abundant lithic industry and well-structured hearths at all levels. Carbon-14 dates from charcoal establish a continuous chronology indicating human occupation from 6,160 130 to 32, 160 100 years BP.

Zwicky proposed that the redshifts astronomers observed in the spectra of celestial objects might not be due to universal expansion but rather to "tired light." In other words, the wavelengths of the photons entering our telescopes are redshifted because they have lost energy through interactions with matter en route to earth. The "tired light" theory was eclipsed by the esthetically appealing concepts of the Big Bang and Expanding Universe. But not everyone has forgotten Zwicky's tired light. P. LaViolette has: ". .. compared the tired light cosmology to the standard model of an expanding universe on four different observational tests and has found that on each one the tired-light hypothesis was superior. The differences between the rival cosmologies are most apparent at large redshifts, however, and it is in this region that observations are most difficult to make." (Anonymous; "New Study Questions Expanding Universe," Astronomy, 14:64, August 1986.) Gratuitous comment. In all three of the foregoing items, observations are challenging fundamental astronomical hypotheses: the Big Bang, the Expanding Universe, redshifts as cosmological yardstocks, etc. With more and more such data accumulating all the time, the strains in the key girders of astronomical thought are beginning to show. Of course, most astronomers will vehemently deny this assertion. Those who care to read the biological tidbits that follow will discover that biological paradigms are also feeling the pressure of ...

The colliding particles usually fragment one another and in the process release a variety of subatomic debris and energy. Large arrays of detectors surrounding the collision site record the particles as they streak away. Usually the escaping particles can be easily identified; but in 1983 nine strange events were recorded, and more have occurred in 1984. Something both invisible and inexplicable carried off large amounts of energy during these "strange" events. Physicist Carlos Rubbia, of CERN and Harvard, said: "There is no sensible way to explain the missing energy by known particles." Some theorists believe that these anomalous events will be explained only by invoking what is termed "supersymmetry" theory. Supersymmetry predicts that twice as many particles as those known today must exist. Already, physicists are rushing to name the new, though unverified particles. The symmetric partner of the "quarks" will be the "squarks"; the "photon" will be paired with the "photino"; there will be the "selectron" for the "electron"; and so on.

A strong consensus has these small, drop like glassy bodies originating when meteors smash into the earth, liquifying themselves and some of the surface rocks. The resulting liquid droplets solidify in flight and when they descend form "strewn fields" hundreds, even thousands, of miles in extent. The main argument has been over whether the actual impact craters giving rise to the tektites might actually be on the moon instead of the earth. Looking over the literature, one sees that this debate has been characterized by much invective and scientific infighting. Today, most scientists concur that some tektite strewn fields are definitely associated with specific, although distant, meteor craters on the earth's surface. Unfortunately, the large separations of craters and strewn fields add a circumstantial flavor to the evidence. However, some tektite-like objects are to be found in the immediate vicinities of terrestrial craters, but not in far-flung strewn fields; viz., the Aouelloul Crater in Mauritania, and the Zhamashin Crater in the USSR. Another example has now come to light: the Lonar Lake Crater, a 50,000-year-old impact crater, in the Deccan flood basalts in India.

Etched into a sloping hill at Pisco Bay on the Peruvian coast, this strange figure looks vaguely like a candlestick; thus, its name "The Candelabra of the Andes." The Candelabra is 595 feet long and can be seen from as far as 12 miles out to sea. Pottery found near the figure has been carbondated at 200 BC and is assignable to the Paracas Culture. Separated by 130 miles from the Nazca Plain, with its famed giant figures, the Candelabra apparently is not the work of the Nazca people.

Well, we don't have any more contradicting data (of which there is plenty), but we do have: (1 ) A new theory which shows how noncosmological redshifts can occur; and (2 ) Laboratory demonstrations of "spectral noninvariance" that show how a non-Doppler component can be added to light's redshift. The physicist behind this new research is E. Wolf, at the University of Rochester. His theoretical work was re-ported in the March 3l, 1986, issue of Physical Review Letters. There he showed how quasars and so-called "superluminary" astronomical sources might emit light with a spectrum that evolves as it travels through space. Scientists have always assumed that once light left its source its spectrum remained unchanged. But Wolf shows how spectral changes are "sort of coded into the light due to correlations in the source." Meanwhile, two of Wolf's colleagues have backed up his theory in the lab. The consequences of Wolf's work would in effect shrink the universe, because objects would not be as far away as we now calculate from their redshifts. The size of the universe might contract ...

Broadcasting at only 76 hertz, this long antenna can communicate effectively with submerged submarines. Although the antenna produces electromagnetic fields about the same as those from a large household appliance, some of the trees adjacent to the antenna have enjoyed an unexpected spurt in growth, according to D. Reed and G. Mroz of the Michigan Technological University. "The researchers have been gathering data on the growth of trees since 1985, making measurements at two sites, one near the antenna and the other 50 kilometers away. The results seem to suggest that the electromagnetic field has a subtle influence on the forest. They found that two species of trees, northern red oak and paper birch, do not seem to be influenced by the antenna at all. But red pines near the antenna grew taller than red pines at the distant site, while aspen and red maple grew thicker than their counterparts further off."

In the case of quasar 3C279, the apparent velocity of expansion was ten times that of light. The quasars all have rather large redshifts, indicating great distances from earth, but the lone galaxy displaying "superluminal" expansion has a redshift of only 0.032. This fact suggests that superluminal velocities cannot be employed as arguments against redshifts being cosmological; that is, measures of distances from earth. Therefore, if the redshift is truly a measure of distance (as it seems to be), some astronomical structures (perhaps not matter itself) seem to grow faster than the velocity of light.

The essay goes far beyond the happy flamingo. It is about unusual adaptations in nature, as illustrated by three inverted or partially inverted creatures. The flamingo is a filter-feeder that strains food out of the water with its bill while its head is upside-down. The flaming's bill and tongue are (and must be ) radically different from those of other birds to succeed in this strange behavior. One type of jellyfish, rather than swimming around with its pulsating bell on top, plunks itself upside-down on the bottom and uses its bell as a suction cup to anchor itself. It then shoots poisonous darts attached to strings of mucous at passing targets and reels them in. Some African catfish graze on algae on the undersides of water plants. They swim upside down all the time and display a reversed color scheme, being black on the bottom and light on top. Gould employs these three examples to argue that changes in animal behavior must have preceded the many changes in form, function, color, etc. that make upside down living profitable. In other words, the proto-flamingos tried feeding with their heads upside down; and it didn't work too well. But "nature" responded with a series of random biological changes ...

Taking into account the 1000,000-year age of the gravel and the slow subsidence of the Hawaiian Islands, the deposit probably reached 380 meters when it was first formed. The big question is how it got deposited at such great heights. Highsea stands are rejected by the authors in favor of a single episode of catastrophic waves about 100,000 years ago. Earthquake-generated tidal waves are considered unlikely because of the great heights involved. (The highest tsunami ever recorded in historical times reach ed only 17 meters above sea level.) A great meteor impact or submarine volcanic explosion are good possibilities, but the authors favor a giant submarine landslide on the Hawaiian Ridge, noting that in 1958 a similar event off Alaska produced a wave that reached 524 meters above sea level.

(SF#110) The media have said little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm the immense amounts of gases precariously locked up in sea-floor sediments.

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 Siberian sites have yielded no hominid bones nor have animal bones of any kind been found; and (2 ) The dating of the tools is shaky. They cannot be radiometrically dated. Instead, Mochanov has had ...

At an elevation of 640 feet, it commands an almost 360 view. Its long axis is aligned with the Pole Star. The cairn seems to have been constructed according to some plan rather than just being a deposit of cleared stones. One's first impression is that it resembles a boat. Could it be a Norse "ship burial" such as found in Europe? It is impossible to prove such a conjecture without tearing the cairn apart.

Science Frontiers ONLINE No. 4: July 1978 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects What caused the grooves on phobos?Photographs from the Viking Orbiters show that the Martian satellite Phobos displays a heavily grooved surface. Enough high-resolution photos have been taken to prove that these grooves emanate from the large crater named Stickney and run around the satellite to its opposite side where they die out. This suggests that the origin of the crater and the grooves are related. Further, the widest and deepest grooves (700 meters wide and 90 meters deep) are located close to Stickney. On the other side of Phobos, grooves are consistently less than 100 meters wide. Despite these hints of impact origin, the grooves are not quite what one would expect from simple fracture by collision. Some show beaded or pitted structures. Other grooves are composed of irregularly bounded segments. Finally, some of the straight-walled sections seem to have slightly raised rims. Evidently, some internal forces, perhaps stimulated by the formation of Stickney, also played a part. (Thomas, P., et al; "Origin of the Grooves on Phobos," Nature, 273:282, 1978.) Reference.

Apr 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mysterious Bright Arcs May Be The Largest Objects In The Universe Several brilliant bluish arcs, some 300,000 light years long, were unexpectedly discovered during a survey of galactic clusters. R. Lynds, of Kitt Peak National Observatory, estimates that the arcs are as luminous as 100 billion suns. The nice circularity of the arcs is perplexing; and it is stated that nothing like them has been reported before. The arcs might be incandescent gas, but many astronomers opt instead for swaths of bright young stars. Spectroscopic tests will decide this point. It has been difficult to conceive of an origin for the arcs. Are they blast waves or the results of tidal action between galaxies? No one knows, for all suggestions seem flawed. Something out there not only manipulates stupendous amounts of mass and energy but also does it with a draftsman's compass. (Anderson, Ian; "Astronomers Spot the Biggest Objects in the Universe," New Scientist, p. 23, January 15, 1987.) Comment. In the interest of accuracy, it should be noted that some superclusters of galaxies are larger than the arcs. Also, some similar phenomena are described in our Catalog volume Stars, Galaxies, Cosmos, viz., the stacked, interleaved arcs of stars around elliptical galaxies (AWO5) and ring galaxies without significant nuclei (AWO6).

Now, a good daytime description of actual crop-circle formation is at hand. Even so, the whole business still sounds pretty mysterious. The source is a letter to G.T . Meaden, Editor of the Journal of Meteorology, U.K ., from R.A . Barnes. "I have been meaning to write to you for some time on the subject of corn circles. About six or seven years ago I was fortunate to see one of these form in a field at Westbury. It happened on a Saturday in early July just before six in the evening after a thunderstorm earlier that afternoon; in fact it was still raining slightly. "My attention was first drawn to a 'wave' coming through the heads of the cereal crop in a straight line at steady speed; I have since worked this out to be about fifty miles per hour. "The agency, though invisible, behaved like a solid object throughout and did not show any fluid tendencies, i.e . no variation in speed, line or strength. There was no visual aberration either in front, above or below the advancing line. "After crossing the field on a shallow arc the 'line' dropped to a position about 1 o'clock and radially described a ...
