In view of this it would appear that certain exceptional observations made on Sunday 21 August 1988 would be worthy of recording. "Out on an afternoon drive M.

That was Sheep Circle 1 on the plan where 'a hundred or so sheep were in a circular formation, each sheep being more or less equidistant from the next. At the north end of the field some 20 or 30 cows were standing, grazing and chewing cud in the usual haphazard manner.

Cyclothems may also be useful. Cyclothems are groups or bundles of strata that repeat themselves in stratigraphic columns. A generalized cyclothem from Illinois is shown in the illustration. In the U.S . western interior, rhythmic sedimentation appears in the Fort Hays Limestone Member of the Niobrara Formation. These cyclothems can be correlated over distances exceeding 800 kilometers and are believed to be the consequence of climatic changes associated with the earth's precession and orbital eccentriciy. These rhythms have been captured in bundles of shale-limestone couplets. A bundle of five coup lets, for example, is thought to express 21,000- and 100,000-year Milankovitchtype climatic cycles, as impressed by variations in the earth's orbital precession and eccentricity. Analysis of the Fort Hays Limestone Member, however, reveals that while bundles of five couplets do occur, the number may vary from 1 to 12. Clearly, things are not clear-cut.

Gas, condensed into stars, is radiating thermonuclear energy out across an infall of matter, drawn by gravity. The simplest of chemical reactions and the most complex of biological activities are occurring on the surface of the earth in a state far from equilibrium; they are heated by the sun and cooled by the vacuum of space. This pervasive cosmic imbalance is the driving force in producing an environment conducive to the formation of structure and complexity." This sweeping statement seems to apply to the entire universe. The Second Law of Thermodynamics, however, insists that, on the average, for the entire universe, the above paragraph cannot be true. The article introduced by this unqualified assertion about the evolution of the universe is really about self-organizing chemical reactions.

This mysterious "talent" can be enhanced by hyp notism, indicating perhaps that it is latent in us all. "The production of eidetic-like imagery during hypnosis in subjects with high but not low hypnotizability was supported in three separate experiments using nonfakable stereograms. In Experiment 1, 6 (25%) of 24 stringently chosen, high hypnotizables were able to perceive one of the superimposed stereograms (presented monocularly) during conditions of standard hypnosis or age regression, or under both conditions, but not during waking. In Experiments 2 and 3, low and high hypnotizables were presented stereograms in an alternating, monocular fashion (one-half to each eye).

Computations on a supercomputer revealed to these three researchers that, if the protoplanet had hit Mercury at between 20 and 30 kilometers/second, then its dense iron core would have survived pretty much intact. A lower velocity would not have stripped off the lighter outer layers; anything higher would have blasted the whole planet into smithereens.

We will save this anomaly for another day, the one we are after now is called: The Winding Dilemma. N. Comins and L. Marschall elaborate as follows: "Stars closer to the center of a spiral galaxy don't have as far to go to complete an orbit as stars located farther from the center. Thus, inner stars should orbit more frequently than outer stars, resulting in a spiral that gradually winds up as the galaxy ages. But observations of spiral galaxies at various distances -- and thus at different stages in their evolution -- have shown that this is not the case. Astronomers believe density waves, stochastic star formation, or perhaps a combination of both processes may sustain or regenerate the spiral pattern." Density waves have recently been applied to explain the spiral rings of Saturn, and now to the arms of spiral galaxies. The density waves are thought to stimulate the condensation of bright new stars as they move through space. A good analogy is the bioluminescent wake of ship in tropical waters. The density waves in a galaxy maintain the spiral pattern with new stars, while the old stars die out (in much less time than it takes for them to orbit the hub) as they orbit out of the spiral pattern. Postulating density waves just raises more questions, as is often the case in science. What causes the density waves? Theory says that the density waves should damp out in under ...

Johnson, is the northeastern Bering Sea, where sensitive side-scanning sonar has sketched large numbers of pits and furrows in the shallow sands. The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried organic matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C.

The only viable alternative is origin by lunar volcanism, which implies the following: continuance of (rare) explosive lunar volcanism to the present time; existence of silicic lunar volcanism and of small patches of silicic rock at the lunar surface; a body of rock in the lunar interior, probably at great depth, which is closely similar to the earth's mantle and which contains billions of tons of volatiles, probably including hydrogen; and the origin of the moon from the earth after the formation of the earth's core."

"The discovery of a surprisingly high deuterium/hydrogen ratio on Venus immediately led to the speculation that Venus may have once had a volume of surface water comparable to that of the terrestrial oceans. We propose that the evaporation of this putative ocean may have yielded residual salt deposits that formed various terrain features depicted in Venera 15 and 16 radar images. "By analogy with models for the total evaporation of terrestrial oceans, evaporite deposits on Venus should be ar least ten to hundreds of meters thick. From photogeologic evidence and insitu chemical analyses, it appears that the salt plains were later buried by lava flows. On Earth, salt diapirism leads to the formation of salt domes, anticlines, and elongated salt intrusions -- features which have dimensions of roughly 1 to 100 km. Due to the rapid erosion of salt by water, surface evaporite landforms are only common in dry regions such as the Zagros Mountains of Iran, where salt plugs and glaciers exist. Venus is far drier than Iran; extruded salt should be preserved, although the high surface temperature (470 C) would probably stimulate rapid salt flow. Venus possesses a variety of circular landforms, ten to hundreds of kilometers wide, which could be either megasalt domes or salt intrusions colonizing impact craters. Additionally, arcuate bands seen in the Maxwell area of Venus could be salt intrusions formed in a region of tectonic stress. These large structures may not be salt features; nonetheless, salt ...

Now, in a strange turn-about, a creationist writer is using evolutionary theory to infer a very short history for the formation where geologists want a good deal of time. We quote from the conclusion of J.R . Meyer: "If any group of animals were ever going to undergo significant degrees of evolution from parent stock and obtain resultant speciation, surely the Kaibab squirrel would be one of the more likely candidates. Supposedly isolated from their neighbors for hundreds of thousands of generations over a period of at least several million years, and significantly violating virtually every restriction of the Hardy-Weinberg equilibrium for the non-evolving population, these organisms, even by creationist standards, should have undergone significant and detectable changes. In reality all they show are moderate changes, primarily in two coat color characteristics for part of their population. To make things even worse, this species is known to have a highly variable coat-color polymorphism throughout its range. Thus, even the differences displayed appear to be easily accounted for by several mutations and a slight change in gene frequency for one or two loci, all occurring in a limited period of ...

The Everglades region is a swampy, forested area surrounded by an oval-shaped system of ridges. Geologists usually maintain that the Everglades represent a collapse feature caused by groundwater dissolving away limestone. (Buildings and cars seem to be swallowed fairly regularly by Florida sinkholes.) Petuch disagrees with the collapse theory and points to the following evidence for an impact origin: 1. The presence of a strong positive magnetic anomaly; 2. Eocene formations, 40 million years old, are missing over the southern Everglades; 3. A network of fractures pervades rock layers older than Eocene; 4. High iridium concentrations, probably of extraterrestrial origin, exist at the Eocene-Oligocene boundary on nearby Barbados; and 5.

Basically, the hypothesis maintains that the forms of things (from crystals to life forms) and the behavior of organisms is influenced by "morphic resonance emanating from past events." Convergent evolution, wherein human eyes closely resemble squid eyes, might well be explained by the hypothesis. Sheldrake has been testing his idea in various ways. One experiment involves the accompanying illustration containing a hidden image. Once the solution of this illustration is learned, it is hard to forget, but few people see the answer right off. The hypothesis of formative causation insists that once one or more persons learn the drawing's secret, the easier it will be for others to see the solution. Actual tests consisted of broadcasting the illustration and its solution (that is, the hidden image) on English television combined with before-and-after checks elsewhere in the world outside TV range.

Two aspects of the fossils are of special interest: The animals found were already well-adapted to terrestrial life, inferring that the (assumed) invasion of the land from the sea has to be pushed back much farther in time; and Many of the fossil animals are essentially identical to modern forms, suggesting that little if any evolution has occurred in 380 million years.

... the corn genome, but she adds some examples of other genomic responses to external stresses. One such stress is applied to an oak tree when a wasp lays its egg in a leaf. The stress causes the oak genome to reprogram itself and construct a wholly new and unplanned plant structure to house and feed the developing insect. Some of these structures (galls) are very elaborate and are precisely tailored to each different wasp species. From such examples, it is apparent that the genome of an organism somehow perceives stresses and reacts to them -- often in completely unanticipated ways. The stresses may be mechanical, thermal, chemical; in fact, almost anything. McClintock's conclusion is: ". .. that stress, and the genome's reaction to it may underlie many formations of new species." (McClintock, Barbara; "The Significance of Responses of the Genome to Challenge," Science, 226:792, 1984.) Comment. The implications here are broad and deep. Evolution can be driven by external stresses. The new species thus produced may differ substantially from the original organism, eliminating the need to look for "missing links" in the fossil record. What "hope-ful monsters" are latent in our human genome, awaiting only the right stresses to manifest themselves? And is the genomes's malleability reversible; that is, can extinct species be recovered when the engendering stresses are removed? From Science Frontiers #37, JAN-FEB 1985 . 1985-2000 William R.

... Highlands Mima Mounds are rarely reported outside the western United States. But Kenya has them, too. At elevations of 1500-3600 meters on Mt. Kenya, fields of mounds up to 6 meters in diameter and 1.5 meters high have been described. Cox and Gakahu have studied some of these African mounds and find them much like the North American Mima Mounds. They are found well above the range of the rhizomyid mole rat, a rodent similar to the North American pocket gopher in size and behavior. Quantitative measurements indicate the mounds to be constructed from dirt immediately surrounding the mounds. In short, the African mounds and probably those of North America seem to be the products of industrious rodents.

Science Frontiers ONLINE No. 36: Nov-Dec 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Subterranean Electric Currents We have little appreciation of the immense electrical currents that flow through the rock formations beneath our feet. These "telluric" currents are primarily those induced by the earth's changing magnetic field, as it is affected by the solar wind. Telluric cur-rents do not flow uniformly through the earth's crust. Rather, they seek out low resistance rocks, in accordance with Ohm's Law. Such current concentrations can be detected at the surface with magnetometers. The present paper announces the discovery of a regional telluric current flowing in the vicinity of the San Francisco Peaks volcanic field in Arizona. The shallow part of the current flows in an unidentifiable "geoelectrical" structure not more than 10 kilometers below the surface. There are no surface hints as to what this geoelectrical structure could be. (Towle, James N.; "The Anomalous Geomagnetic Variation Field and Geoelectric Structure Associated with the Mesa Butte Fault System, Arizona," Geological Society of America, Bulletin, 95:221, 1984.) Comment. Similar anomalous magnetic fields exist in many areas, indicating a vast subterranean system of poorly understood geoelectrical structures. Some of the channeled earth currents are man-made, being the return paths in electrical power transmission systems. The return paths may be far-removed from the actual power lines because they tend to follow the geoelectrical structures. Reference. Other important subterreanean electrical currents are described in ...

... Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Galactic radiation belt?Both Jupiter and the earth boast radiation belts consisting of electrically charged particles tethered by the planet's magnetic fields. Recent radio astronomical studies of the Milky Way reveal long filaments of ionized gas about 150 light years long curving up out of the galactic disk, at a point about 30,000 light years from earth. These filaments emit radio energy just like the planetary radiation belts and are presumably held in the grip of a galactic magnetic field. There have been previ-ous hints of a weak and disorganized galactic magnetic field, but this is the first evidence for a strong polar field in our own Milky Way or any other galaxy. The unexpected filaments were discovered by in a study of star formation in the core of the Milky Way. The radio energy emitted by the belts was originally thought to come from the galactic machinery that makes new stars; but now it looks like that machinery is not grinding out nearly as many new stars as once thought.

... volume of sediment removed is not the real issue. The first problem emerges downstream from Red Butte at Pierce Ferry. There we find 200 meters of Hualapai limestone, which has been dated at 8.7 million years from a thin layer of volcanic ash within the limestone. When this limestone was laid down, the geology is emphatic that no large, sediment-carrying river was in the vicinity. Most geologists agree that the lower end of the Grand Canyon was not active around this time. No one knows where the Col-orado River was flowing at this period. Some say southwest from Peach Springs; others point to a northwest route into Utah. All the likely alternate routes face serious geological obstacles such as lava barriers. What does seem certain is that the stock explanation of the formation of the Grand Canyon is incorrect. It was not steadily ground out, cutting everdeeper as the whole region was slowly elevated. Actually, geologists believe that the region stopped rising over 50 million years ago. Where, then, did the sediments from a 450-kilometer canyon and the wide areas surrounding its rims go? The present exit of the Colorado near Pierce Ferry was blocked until fairly recently while the Hualapai limestone was being deposited; and other routes don't look too promising. (Rice, R.J .; "The Canyon Conundrum," Geographical Magazine, 55:288, 1983.) Comment. Moral: beware of facile explanations. The data presented, in fact, make one wonder whether all of the erosion might have occurred quite recently (perhaps when ...

Arabian Sea. "At 1552 GMT bioluminescence in the form of diffused white light in 'whirlpool' and 'cartwheel' formations was observed; within 3 minutes it completely encircled the vessel and extended to the horizon. The 'cartwheel' formations were brightest at the centre with a halo effect surrounding the outer edges. As the vessel passed over 2 such formations the 'spokes' were estimated to be 2-2 metres in width and the entire concentration, which was more than the width of the vessel (approximately 27 metres), was observed on both sides of the bridgewing simultaneously. The 'whirlpool' formations, with a distinct central hub, varied from l to 2 metres in width and from 14 to 15 metres in length. The phenomenon was observed for 40 minutes."
