All around the Pacific Basin, scientists have been collecting evidence that, between 12,000 and 5,000 years ago, El Nino was virtually nonexistent and that its reappearance coincided with great cultural changes. To illustrate, coral records from the western Pacific and sediments in the Great Lakes indicate that El Nino was going strong before 12,000 BP, but then there was an unexplained, 7,000-year lull. This lull is also seen clearly in sediments in Laguna Pallcacocha, a lake in the Andes of southern Ecuador, so is El Nino's sudden resurgence around 5,000 BP. This resurgence and the associated worldwide climatic turmoil also marks the emergence of complex societies all over the planet. The Egyptians built pyramids, the Peruvians constructed temple mounds, civilizations rose and collapsed in the Middle East, and settled agrarian societies developed in many locations. Although not all cultures responded well to the climate changes, El Nino seems to have sparked the rise of modern civilizations. We are assuming that this was good!

The strong implication was that TLPs (Transient Lunar Phenomena) are observer illusions. Anomalists instinctively bristle at such dogmatic assertions. Especially with TLPs, because hundreds of light flashes and color changes have been seen on the moon by reliable astronomers ever since Galileo made his first telescope. A satisfying rebuke to the TLP naysayers was recently delivered by JPL's B. Buratti at the October 1999 meeting of the American Astronomical Society in Padua, Italy. Her specific TLP occurred on April 23, 1994. At that time, about one hundred amateur astronomers noticed a 40-minute darkening near the edge of the bright lunar crater Aristarchus. Happily, when this hundred-fold "illusion" took place, the lunar satellite Clementine was mapping the area around Aristarchus. Defying the dogmatists, Buratti scrutinized the Clementine data again. Sure enough, Aristarchus had really turned redder after the TLP reported by the amateur astronomers. Such lunar color changes are readily explained as due to eruptions of pockets of gases trapped below the moon's surface. These blow-outs can spread colored dust over areas extensive enough to be visible through the small telescopes used by amateur astronomers.

... Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Nuclear bombs will not save the earth!Not too long ago, geologists adamantly denied that there were any large meteor craters pockmarking our planet. Now, they find 100-kilometer craters on a regular basis. And scientists are casting worried looks at those near-earth asteroids, knowing that one day one will be on a collision course. Not to worry, say the modern-day Technocrats, we will launch nucleararmed rockets that will nudge such cosmic threats into harmless trajectories. These Pollyannas are presumptious. They assume that asteroids are hard, cohesive objects that will be shoved aside by a few megatons of explosive energy. There are two things wrong with this idea, and these reveal how radically our ideas about the nature of asteroids have changed in just 10 years. First, most astronomers will now agree that asteroids are orbiting rubble piles rather than monolithic objects. For example, the near-earth asteroid Mathilde, 53 kilometers in diameter, has a density of only 1.3 grams/cubic centimeter. Its porosity must be greater than 50%. It is not a hard, coherent object. Instead of a bullet, it is more like a cloud of shotgun pellets. It would be hard to divert all this debris with a nuclear blast. To make matters worse, asteroids like Mathilde are stickier than a cloud of buckshot. This fact is deduced from photos of asteroids showing many to be marked by huge craters. (Mathilde has one 33 kilometers wide.) K.R . Housen et al, using ...

... hybridization" method simply mixes together strands of DNA from the two species being compared. These are allowed to combine, and then they are heated to see how much temperature is required to force them apart. Chromosome numbers and bandings have little if any effect on these crude comparisons of the bare DNA strands that have been stripped from their genes and chromosomes. The significance of all this transcends the comparisons of humans and chimps. Modern taxonomy of all life forms depends increasingly upon DNA comparisons rather than upon morphology. If DNA comparisons can be as misleading as they are in humans and chimps, those textbook family trees that are supposed to tell us how life evolved may also be giving us an erroneous history of life. To underscore the problem, sometimes DNA genetic differences do not result in big morphological changes. For example, Three-toed Woodpeckers hammer on trees all over the northern reaches of North America and Eurasia. These birds all look alike and interbreed freely. Yet, some of the birds differ so much genetically that they should be classified as different species on that basis. (See BBG1 in Biological Anomalies: Birds.)

It is the second component that can be controlled so as to mirror natural sounds. The result is like nothing Mozart or Verdi conceived. But it is an art form valued in Tuva and a talent rather remarkable from a biologist's perspective. One should compare the vocal tract to an organ pipe with its standing waves, except that the human pipe is only 7 inches long in the average adult male. One end of the human pipe is the mouth; the other is at the so-called "vocal folds" deep in the throat (larynx). To control their "instrument" throat-singers move their tongues back and forth to change the standing waves in the vocal tract. The source of raw sound is the vocal folds. It is the vocal tract that shapes the raw sound into musical tones. Biofeedback is also involved as the throatsingers tweak the rate and manner in which the vocal folds open and close. (Levin, Theodore C., and Edgerton, Michael E.; "The Throat Singers of Tuva," Scientific American, 281:80, September 1999.) Comments. The human throat is obviously a complex musical instrument, but what survival value does this remarkable instrument have? Did evolution overshoot its mark? Incidentally, many birds can produce simultaneously two tones that are not harmonically related. However, these birds have a special doublebarreled organ called the syrinx. So, the avian "two- ...

This prescience verges on the miraculous to the uninitiated, but mainstream biologists seem content to write the phenomenon off as merely good fortune -- like hitting two jackpots in a row on the same slot machine. A good example of preadaptation occurs when bacteria are cultured in the presence of an antibiotic. Within a few weeks, they have evolved a resistance to that particular antibiotic. This well-known phenomenon is easily explained by evolution. However, often the newly evolved (or "adapted") bacteria are also resistant to several other antibiotics that work by different mechanisms. All of the multiple gene changes needed for the several different defense mechanisms are controlled by a single site on the same chromosome. (Levy, Stuart B.; The Antibiotic Paradox , New York, 1992, p. 99. Cr. A. Mebane.) Comments. How can bacteria prepare defenses against antibiotics they have not been exposed to? Luck, prescience, or some unrecognized mechanism? In his Ever Since Darwin , S.J . Gould acknowledges that "preadaptation implies prescience although in actuality it means just the opposite! His explanation of "preadaptation is not easy to grasp. "In short, the principle of preadaptation simply asserts that a structure can change its function radically without altering its form as much.

... experiencer reports from over 100 different types of EEs. Preliminary study shows that those individuals who begin to explore their EEs and question conventional answers may undergo a series of similar developmental, predictable, humanizing, and transformative stages of expanding conscious awareness, which we call the Exceptional Human Experience Process (EHE Process). When EEers begin to comprehend and realize that their experiences are more than external phenomena happening "outside" of them and instead signify a whole inner and outer personally meaningful experience, the EE becomes potentiated into an EHE. EHEers report greater numbers of EHEs including meaningful insights, heightened creativity, and "lucky coincidences." Over time, or additional EEs/EHEs, or with a tremendous burst of insight, a subjective threshold is crossed. The experiencer's lifeview and whole worldview changes, and a new perspective (i .e ., double vision) is forged. Fresh transpersonal connections with a new vision of self and the world become established. In hindsight, advanced EHEers report that the whole process was life-changing and somehow felt "destined." It is at this stage of the EHE Process where the EHEer has literally transcended everyday "normal reality" and discovered with clarity and quiet wisdom his or her unique "calling" in life, and the calling to an evolution of consciousness for all life."

There was a band measuring 35 long in azimuth, with deepblue almost black vertical bands lying between the altitudes of 15 and 25 . The colour changed to brilliant blue at 0335, lasting for about 15 minutes before cloud began to obscure it." What were the "almost black" vertical bands embedded in the main band? Aurora expert R. Livesey replied as follows. "There is a phenomenon called the 'black aurora' which consists of small regions of very low luminosity embedded in brighter auroral light; the 'black' rays reported from the Appleby could have been a phenomenon of this type." (Wilson, J.L .; "Aurora Borealis," Marine Observer, 69:112, 1999.) Black auroras may actually be more than just the contrast effect suggested by Livesey. Low-light TV systems detect clockwise vorticity in the black bands, and the bands seem to be associated with upward electron beams. In other words, black auroras are apparently a distinct phenomeon in their own right and not just nonluminous parts of the visible aurora.

Skulls thought to be 9,000-12,000 years old have been unearthed in Brazil with features that closely match those of Australians living about 60,000 years ago. Evidence of even earlier contacts comes from stone tools and charcoal at Serra da Capivara, in northeastern Brazil. These artifacts indicate human habitation as long as 50,000 years ago. These very early Australians, however, seem to have been exterminated by a later wave of Mongoloid invaders. W.

Deming ventures that extraterrestrial sources of water and carbon may be four or five orders of magnitude greater than suspected. Obviously, a steady bombardment of icy comets might fulfill Deming's requirements. Down the long eons of geological time, they could have filled the oceans and showered all that excess carbon onto the planet's surface. Deming ups the stakes in the icy-comet controversy when he links these fluffy snowballs to the well-known vagaries of life on earth. "The extraterrestrial influx rate may also act as the pacemaker of terrestrial evolution, at times leading to mass extinctions through climatic shifts induced by changes in accretion rates with concommitant disruptions of the carbon and nitrogen cycles. Life on earth may be balanced precariously between cosmic processes which deliver an intermittent stream of life-sustaining volatiles from the outer solar system or beyond, and biological and tectonic processes which remove these same volatiles from the atmosphere by sequestering water and carbon in the crust and mantle."

Reddish glows around the rims of the craters Aristarchus and Alphonsus have long been accepted as objective scientific observations. The most popular explanation of these color phenomena involves the eruption of gases around the craters. In 1964, in an attempt to better understand TLPs, NASA organized a network of amateur lunar observers with communication links to the Corralitos Observatory in New Mexico. Corralitos possessed a 5-inch reflector equipped with color filters which could checkout network sightings. In almost 3,000 hours of surveillance, no color phenomena were recorded using the Corralitos instruments -- even when the network reported a colored TLP in progress. Are all TLPs therefore illusory?

Activity levels within ant colonies are monitored by using a solid-state automatically digitizing camera. The movement-activity levels of whole colonies and of isolated groups of workers are studied. Whole colonies of Leptothorax allardycei show rhythmic changes in movement-activity level. Fourier and autocorrelation analyses indicate that the activity levels of colonies are periodic, with an average period of 26 min. Single, isolated workers do not show the pattern of periodic changes in activity level. Single workers become active spontaneously, but at no particular interval. Pairs of workers, confined together, also do not show periodicity in activity level. One worker can stimulate another worker to become active, thus coupling their movement-activity patterns. As ants are placed in larger groups, the variation in the interval between activity peaks declines in a manner predicted by coupled oscillator theory. It is argued that the colony can be regarded as a population of 'excitable subunits.," Activity records from two ant colonies. Time (horizontal axis) is measured in 30-second intervals.

... about far-fetched. It is called "lucid dreaming." F. van Eeden, a Dutch psychiatrist, defined lucid dreaming in this way: ". .. the reintegration of the psychic functions is so complete that the sleeper reaches a state of perfect awareness and is able to direct his/ her attention, and to attempt different acts of free volition. Yet the sleep, as I am able confidently to state, is undisturbed, deep and refreshing." Lucid dreams are real dreams. They occur during REM (Rapid Eye Movements) sleep, usually in the early morn ing, and they last 2-5 minutes. High levels of physical and emotional activity during the preceding day can encourage lucid dreaming. When lucid dreaming occurs, there are pauses in breathing, brief changes in heart rate, and changes in the skin's electric potential. There is even a recipe for triggering lucid dreaming. If you awake from a normal dream in the early morning, wake up fully but don't forget the dream. Read a bit or walk about, then lie down to sleep again. Imagine yourself asleep and dreaming, rehearsing the dream from which you awoke, and remind yourself: "Next time I'm dreaming, I want to remember I'm dreaming." Lucid dreaming, it seems, is not an isolated phenomenon. There are strong similarities between lucid dreaming and out-of-the-body experiences and even the experiences of UFO abductees. S.

Mars is a classic case, being much more heavily cratered in its southern hemisphere than its northern. But the dichotomies are not restricted to cratering, as we shall now see. Neptune . Recently, H.B . Hammel, using the University of Hawaii's 2.2 -meter telescope, discovered that Neptune's northern hemisphere is now brighter than its southern -- something never observed before. During the past eight years, the southern hemisphere has been consistently brighter, although the hemispheres were of roughly equal brightness during the late 1970s. The cause of these brightness changes remains a mystery. (Cowen, Ron; "Neptune's Northern Half Grows Brighter," Science News, 144:287, 1993.) Iapetus . This satellite of Saturn is dark on one half and light on the other. Quantitatively speaking, the bright side reflects ten times more incident light than the other. An explanation is suggested by the fact that the dark side points in the satellite's direction of motion. A recent study of 12 Voyager images of Iapetus also imply an exogenous (externally imposed) origin of the dark surface, because they show a gradual rather than sharp transition between the dark and light regions. The thought of planetary scientists is that micrometeoroids bombard the leading hemisphere of Iapetus preferentially and in the process volatilize considerable surface material.

(SF#45) At that time, they claimed that these finely bedded lava flows testified that, during a field reversal, the earth's field swung around at the astonishing rate of 3 per day! This rate is about one thousand times the current rate of polar drift. Mainstream geophysicists could not believe the 3 /day figure because it implied incredibly rapid changes in the flow of those molten materials within the earth that supposedly generate the geomagnetic field. The Steens Mountain data were "tabled"; that is, dismissed. The three researchers, though, continued their labors at Steens Mountain and have now offered additional, even more impressive data. They now find that the geomagnetic field probably shifted as much as 6 in a single day. Their work has been carried forward so professionally and meticulously that other scientists are finding their conclusions harder and harder to dismiss. Instead, the search is on for explanations of the rapid field changes. Three possibilities have been advanced -- all of them unpalatable to geophysicists: The Steens Mountain rocks are not faithful recorders of the main geomagnetic field.

... entities in the universe. Supposedly powered by a black hole, each quasar emits hundreds of times more energy than all the billions of stars in the Milky Way. Just how a quasar works is surmise. What we now know from two surveys by two different groups of astronomers is that most quasars have redshifts between 2 and 3. In the theoretical framework of the expanding universe, redshifts are proportional to recessional velocity, distance from the observer, and age. From the redshifts, it seems that the quasar epoch spanned the period 1.9 -3 .0 billion years, based on an age of 15 billion years for the universe. Assuming the accuracy of this scenario, cosmologists now have to explain why quasars were born and flourished in such a narrow time slot. Did something fundamental change in the universe between 1.9 and 3.0 billion years ago? (Kaiser, Jocelyn; "Epoch of Quasars," Science, 269:637, 1995.

On June 8, 1994, what may be the largest deep earthquake of the century -- magnitude 8.2 -- exploded 640 kilometers beneath Bolivia. "Exploded" may or may not be the proper word. Geophysicists are really not certain what causes the very deep quakes, because at 640 kilometers rocks are so hot that they flow rather than snap under geological stresses. The more common, shallow earthquakes are generally created when rocks snap and fracture. Since the deep quakes seem to be concentrated in subducted slabs of terrestrial crust that plunge down deep into the earth's mantle, geophysicists suppose that the increasing heat and pressure applied to the descending slabs may cause "explosive" phase changes in minerals contained in the slabs. Phase changes often involve volume changes that, if sudden, might generate seismic waves. Too, water of hydration in minerals may be explosively turned into vapor. But this is all surmise at present. The Bolivian quake also caused the whole earth to ring like a bell. Every 20 minutes or so, the entire planet expanded and contracted a minute but detectable amount. Another surprise: the Bolivian earthquake was felt a far away as Seattle -- the first time that a quake in that part of South America has been actually felt in North America.

The search has revealed that at six times during the last glaciation, huge armadas of icebergs launched from Canada spread across the northern Atlantic Ocean, each triggering a climate response of global extent." The foregoing abstract does not mention the interesting Heinrich layers that fostered the above scenario. In 1988, H. Heinrich published a paper describing a curious set of sedimentary layers found in cores drilled in the tops of the Dreizack seamounts in the eastern North Atlantic. Heinrich concluded that each of the six layers he found represented the melting of "six great armadas of icebergs." These icebergs carried debris picked up in Canada and, as they melted, deposited it on the seamounts and ocean floor. Each layer could be correlated with the major climate boundaries revealed by the Greenland ice cores. Very fittingly, these iceberg incursions are now termed "Heinrich Events."

Catchy though this title is, it looks more and more like the Watchmaker sees something. For over a decade, experiments have hinted that those mutations that are helpful to an organism's survival occur more often than those that are not "adaptively useful." This controversial phenomenon is termed "adaptive mutation." (SF#64 and SF#96*) A recent issue of Science presents two more papers that seem to confer the gift of sight on the old Watchmaker.

The application of chaos theory to solar system debris. Shaw hypothesizes that nonlinear gravitational effects channel asteroids and comets into the inner solar system in intermittent bursts. The bursts are then captured by the earth and other inner planets, with some of these objects grouped in like orbits. Gravitational feedback occurs from earth to orbiting debris. Shaw believes that the uneven distribution of mass inside the earth -- due probably to the impact that created the moon -- influences where asteroids and comets impact. In turn, these large objects keep smashing into the same regions and their cumulative effect contols the flow of material inside the earth. Then, this change in mass distribution feeds back to change orbits and impact swaths. The above is just a taste of what is revealed in Shaw's book of 600+ pages. It cannot fail to be controversial.

Old Kingdom craftsmen laboriously cut this hard, black, glassy rock into royal sarcophagi and pavements for the mortuary temples at Giza just outside Cairo. To transport the heavy blocks of basalt from the quarry to Giza, the Egyptians built a quay on Lake Moeris, which then had an elevation of 66 feet above sea level and was located 7 ½ miles southeast of the quarry. (The Lake is now much smaller and 148 feet below sea level, indicating a large climate change.) Then, when the Nile flooded and its waters reached a gap in the hills separating the Lake and the Nile, the Egyptians were able to float the blocks of basalt over to the Nile and down to Cairo. Good thinking! But how did they transport the heavy blocks 7 ½ miles from quarry to quay? The answer: What was apparently the first paved road on the planet. This 4,600-year-old engineering feat averaged 6 ½ feet wide and was paved with thousands of slabs of sandstone and limestone, with some logs of petrified wood thrown in.

(Adapted from ESRS Bulletin, 1:12, 1973) The sophisticated corbelling of the structure closely follows that seen in Irish and Iberic chambers, such as New Grange. The long passageway is aligned with the summer solstice sunset, also a feature of some ancient European structures, but hardly of any concern to a New England farmer. The Upton chamber seems to be associated with linear arrays of stones and stone cairns on nearby Pratt Hill. These alignments have obvious astronomical significance. In fact, based upon changes in the setting positions of several stars (due to precession), Mavor and Dix believe the whole complex dates back to 700-750 AD. They conclude: "Of all the enigmatic structures that we have seen in America, the Upton chamber stands out as one that could have been built under the influence of Irish monks in the 8th century."

Science Frontiers ONLINE No. 103: Jan-Feb 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Stythe = choke damp This, according to an unabridged dictionary. Looking up "choke damp", it is found to be "a suffocating gas, chiefly carbon dioxide, found in wells, coal mines, and other pits, also called "blackdamp." Evidently, in the quotation in SF#102 describing the death of one Donald Tollett due to a stythe, the word "stythe" was used for the meteorological event itself rather than -- correctly -- for the gases sucked out of the coal mine by a sudden drop in atmospheric pressure. (Stepp, Richard; personal communication, November 26, 1995) Comment. Changes in atmospheric pressure are also the causes of "blowing caves" and "weather wells". See GHG2 in Earthquakes, Tides, Unidentified Sounds. To order, visit here . Incidentally, blowing caves were used in the very early days of aernonautics for testing aircraft models due to the lack of wind tunnels.

... above title appeared in Science rather than the Creation Research Society Quarterly. (We never thought we'd see the day!) And right beneath, in large type, is: "The most thorough study yet of species formation in the fossil record confirms that new species appear with a most un-Darwinian abruptness after long periods of stability." In the article that follows, R.A . Kerr reviews several recent studies of fossil bryozoans and snails. Some of these painstaking dissections of the fossil record were carried out by scientists initially committed to Darwinian gradualism. Even these researchers have been forced to acknowledge that much biological evolution proceeds not in minute steps but by large jumps or saltations. Such abrupt speciation is tough enough to explain, but even more daunting are those species untouched by change over millions, even hundreds of millions of years. Indeed, the major characteristic of the fossil record and, therefore, earth life as a whole, has been stasis rather than speciation, despite all manner of asteroid impacts and climatic traumas. Nevertheless, many biologists think that species are somehow frozen in time by environmental forces that keep them from straying from their little niches. This being so, paleontologist D. Jablonski, University of Chicago, asks: If stability is the rule, how do you get large-scale shifts in morphology? How do you get from funny little Mesozoic mammals to horses and whales? From Archaeopteryx to hummingbirds? (Kerr, Richard A.; "Did Darwin Get It All Right?" Science, 267:1421, 1995) Comments. ( ...

... external stimuli, such as a specific piece of recorded music. Some lucid dreams do get out of control, however, and become nightmarish. But pleasant, controllable lucid dreams are the general rule. If you can't seem to get into lucid dreaming, apply to the Lucidity Institute, where you can purchase a Nova-Dreamer machine for $275. Thus armed, you can enter that Never-Never Land anytime you want. But how does one know he or she is dreaming lucidly? There is a simple test that is not only strange but probably anomalous. During your dream find a shop or traffic sign, even a dollar bill or newspaper. Then, find a word of four or more letters. Look away, and then look back. If the word has changed when you look back, you are in a lucid dream. For reasons unknown, the brain centers controlling lucid dreaming cannot consistently process words of more than three letters!

... "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."
