Helfer, University of Rochester, noting the absence of extensive cratering on the northern plains of Mars, suggests that some 2-3 .5 billion years ago these plains were covered with oceans. These ancient seas, perhaps as much as 700 meters deep, protected the plains from direct impacts. Further, crater density counts for Chryse and the Martian highlands imply that Mars possessed a fairly dense atmosphere until about 1.5 billion years ago. In his Abstract Helfer speculates as follows: "With both early Earth and early Mars having similar atmospheric compositions and not too dissimilar atmospheric structures, it is reasonable to suppose that the warm Martian oceans, like the ancient oceans of Earth, would develop anerobic and aerobic photosynthesizing prokaryotes and structures like stromatolites. Their development might have changed the Martian atmosphere. Their fossils might be found along the fringes of the old oceans, the northern lowland plains." (Helfer, H.L .; "Of Martian Atmospheres, Oceans, and Fossils," Icarus, 87:228, 1990.) Comment. The Gaia influence is seen in the molding of the Martian atmosphere into something more conducive to the development of life. One can also speculate that, if life did develop on Mars, it could have seeded the earth via bits of debris blasted off by meteorite impacts. Several meteorites picked up in Antarctica are thought to have come from Mars ...

Science Frontiers ONLINE No. 78: Nov-Dec 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Terraforming Mars The concept of terraforming a planet is an old standby of science fiction; it is the process by which a technologically advanced race manipulates the surface and atmosphere of an uninhabitable planet so that it becomes inhabitable. We humans know to our dismay that we have the capacity to modify the earth's environment, but could we perhaps exercise better judgment and terraform Mars? C.P . McKay et al have looked into this possibility: "From our analysis, one could propose the following sequence of events: production of CFCs (or other greenhouse gases) starts on Mars and the surface temperature warms up by about 20 K. The regolith and polar caps release their CO2 and the pressure rises to 100 mbar. One of two things could then happen. If there were large regolith and polar CO2 reservoirs, the pressure would continue to rise on its own. If these were absent, the CO2 pressure would stabilize, and additional CO2 would have to be released from carbonate minerals. At this point (perhaps between 100 and 105 years) Mars may be suitable for plants. If there was a mechanism for sequestering the reduced carbon, these plants could slowly transform the CO2 to produce an O2-rich atmosphere in perhaps 100,000 years. If sufficient N2 could also be released from putative soil deposits, and the CO2 level kept low enough, then a human- breathable atmosphere could be produced. (McKay, ...

Yet, British scientists, I.P . Wright et al, in Nature, come close to such a conclusion. "The meteorite EETA 79001, which many believe to have originated on Mars, contains carbonate minerals thought to be Martian weathering or alteration products. Accompanying the carbonates are unexpectedly high concentrations of organic materials (defined here as carbonaceous matter that has a low stability towards oxidation, and so combusts at less than 600 C; the term 'organic' does not necessarily imply an origin by biogenic processes.) Although the carbon isotope composition of these materials is indistinguishable from terrestrial biogenic components, and so cannot be used to assess the source, we argue here that their occurrence in an interior sample of a clean Antarctic meteority militates against a wholly terrestrial origin. A sample of Martian organic materials may thus be available for further study in the laboratory." (Wright, I.P ., et al; "Organic Materials in a Martian Meteorite," Nature, 340: 220, 1989.) But there are many "buts": Meteorite EETA 79001 may not have come from Mars after all, even though many scientists think it did. The organic material in EETA 79001 may have come instead from the comet that supposedly blasted the meteorite into space from the ...

Terrestrial geologists point to the Channeled Scablands in eastern Washington State as evidence of what the sudden release of a huge lake's water can do to the landscape. Everywhere in this part of Washington are deeply incised grooves and dry cataracts separated by water-streamlined bars. Exactly this sort of harsh, scoured topography can be found at Kasei Valles, Mars. "The upper part of the channel system is typically less than 1 km deep and descends from Echus Chasma about 1 km over a distance of 1000 km; it then splits into north and south channels. On the basis of a stereomodel of Viking images, we have measured the geometry of a steep, constricted reach of the north channel that drops 900 m in only 100 km. A late-stage flood is hypothesized to have scoured the channel. If we assume that channel striations indicate water levels, then the flood had a minimum cross-sectional area of 3.12 x 107 m2 (the putative flood had a width of 83 km, an average depth of 373 m, and a maximum depth of 1280 m).

A livable Mars in past eons is not a physical impossibility. Some scientists argue that Martian geological and geochemical data: ". .. are consistent with past conditions on Mars that were favorable to earth-like life forms: Abundant liquid water and an atmosphere that was dense and warm, and possibly rich in oxygen." That life -- intelligent life -- once thrived on Mars is suggested by photos taken of the Martian surface by Viking spacecraft: "Images of the surface of Mars showing, at several sites what appear to be three carved humanoid faces, of kilometer scale, and having similar anatomical and ornamental details between all three. Appearing with these objects are numerous other objects and suface features that resemble Earth-like archaeological ruins, of a Bronze Age culture, with no evidence of advanced technology or civilization."

This pronouncement may have been premature. A meteorite discovered in Antarctica in 1979 may change a few minds on this matter. This particular meteorite is one of the handful thought to have been blasted off into space by an oblique impact of an asteroid on the surface of Mars. Somehow, statistics were kind to these tiny Martian orphans, for they found their ways to the Antarctic snows. But what is really exciting is the recent discovery that chemical analysis of one of these purported Martian meteorites revealed a high concentration of organic material deep within. The implication is that Martian life existed, perhaps still does exist, beneath the Martian surface, where the Viking Lander's scoop could not get at it. (Anonymous; "Life under Mars?" Sky and Telescope, 78:461, 1989.) Comment. In other words, Mars like the earth, may harbor an unappreciated fauna in crevicular structure beneath the environmentally rigorous surface.

For decades the stock answer has been: from the condensation of vapors escaping from the planet's cooling crust; that is, "outgassing." The possibility that some terrestrial water might have ar rived from extraterrestrial sources after the earth's formation has been discounted. The major reason behind this neglect was the expectation that the erosive effects of large-scale impacts of water-carrying comets and asteroids would preclude any net accumulation of volatiles, and could even reduce any existing inventories of surface water. C.F . Chyba has recently reexamined this question of cometary water influx vs. impact-caused water losses using the latest estimates of comet/asteroid fluxes during the period between 4.5 and 3.5 billion years ago, when bombardment of the inner solar system was thought to be especially severe. Rather than the expected net loss, Chyba computes that the earth would really have gained more than 0.2 - 0.7 ocean masses in that billion-year period. Venus would have fared equally well, but Mars, more sensitive to impact erosion, would have accreted "only" a layer of water 10-100 meters deep over the whole planet! (This Martian water is now mostly below the surface supposedly.) (Chyba, Christopher F.; "Impact Delivery and Erosion of Planetary Oceans in the Early ...

Mortises were cut in some way so that the planks could be joined. It is quite clear that the Neolithic peoples of the region were skilled carpenters.

They had learned that piles of porous rocks could, in desert climes, capture and condense surprisingly large quantities of water. Take, for example, the 13 pyramids of loose limestone rocks that the Greeks constructed some 2500 years ago at Theodosia in the Crimea: "The pyramids averaged nearly 40 feet high and were placed on hills around the city. As wind moved air through the heaps of stone, the day's cycle of rising and falling temperatures caused moisture to condense, run down, and feed a network of clay pipes. "One archaeologist calculated a water flow of 14,400 gallons per pyramid per day, based on the size of the clay pipes leading from each device." Weren't the ancient Greeks clever? But perhaps they had observed how some mice in the Sahara pile small heaps of rocks in front of their burrows and lick the condensed moisture off in the morning.

One of the most bizarre features yet identified on Venus is a remarkably long and narrow channel that [the spacecraft] Magellan scientists have nicknamed the River Styx. Although it is only half a mile wide, Styx is 4,800 miles long. What could have carved such a channel in unclear. Water, of course, is out of the question. Flowing lava is a possibility, but it would have to have been extremely hot, thin, and fluid." Another suggested fluid is sulphur, but there is still room for speculating about exotic fluids, given Venus's high surface temperatures. Another point of interest: the River Styx does not run steadily downhill. It takes an up-anddown course. Either the Venusian topography has shifted since the Styx was cut, or the channel is not a river at all but rather some bizarre geological feature.

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

Ice-penetrating radar sketched the topography of the icerock surface, and surface-gravity measurements assessed density variations in surrounding ice and rock.

If so, how do they ride in to afflict us on the peaks of the solar cycle? Here's how, in their words: "In conclusion, we note that electrical fields associated with intense solar winds can rapidly drive charged particles of the size of viruses down through the exposed upper atmosphere into the shelter of the lower atmosphere, ...

After examination and measurement, the patterns of its carefully inscribed markings are believed to be identifiable as a calendar fashioned for use at Stonehenge. Found over the breast of a skeleton of a tall man, its symmetrical shape and correct corner angles make it appear probable that the plaque had something to do with the four cardinal points and solstitial sunrises and sunsets.

Were the bronze rivets, found nearby, the remains of the alidade? Markings exist on the plaque which indicate that the 16-month calendar was in use. Guide lines exist for inserting the intercalary leap day. Eight additional lines can be identified as indicating moonrise and moonset at the equinoxes' standstills.

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

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."

Only two fire-tongues on the ground were reported, one on snow and the other on a paved parking space without any apparent surface fissure.

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

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

The review, however, is expansive and provides some facts about synesthesia worth passing on to our readers. Syesthesia is an "oddity" of human perception in which words, musical instruments, objects, concepts, evoke sensations sharply different from what is actually being processed by the brain. For example, specific musical tones elicit specific color sensations; that is, B-flat evokes the color green; A-sharp, yellow, etc. Or the phenomenon may be more complex, with Mozart being green; Wagner, red, etc. Most "synesthetites" seem to experience colors, but geometrical figures sometimes appear in response to particular stimuli. As for the stimuli that call forth these exotic sensations; they are usually music or numbers. To some synesthetites, the cardinal numbers are associated with specific colors. The books's author is R.E . Cytowic, and he has provided some very interesting observations about synesthetites: There is much consistency among them; that is, if the number 5 evokes a red sensation with one, it does with most others, too.

Like its relative, the platypus, it is a strange mixture of mammalian, marsupial, and reptilian characteristics. For example, echidna eggs are soft and leathery, like those of reptiles, but they are brooded in a marsupial-like pouch. The emerging baby echidna has an egg tooth like the birds and reptiles, while the adult has no teeth at all. Rather, it has a narrow snout through which it ingests ants and termites caught on its sticky tongue. In this it resembles the mammalian ant-eaters, which are also toothless but an ocean away from Australia. In fact, the echidna is often called a "spiny anteater" for it has the sharp spines of a hedgehog or porcupine. There are more anatomical peculiarities, but let us focus on the echidna's strange behavior during the mating season. At this time, 2 to 8 echidnas can be seen roaming the Australian bush in "trains" headed by a female with the smallest male acting as a caboose. When mating time arrives, the female anchors herself to a tree with her forelegs. To-gether the males dig a circular "mating rut" up to 10 inches deep around the tree.

Moriarity cites Pliny as the earliest historical reference. According to him, Eel Balls occur in Lake Garda, Italy, when it has been storm-tossed by the effects of the October 'Autumn star'. Smitt in his Scandanavian Fishes (1895) says that eels knot themselves together in bunches 'up to a fathom in circumference' and are seen rolling along the stream beds, or, strangely, resting in this position. On 17 August 1935, fishery scientist J.C . Medcof observed, in the outflow of Lake Ainslie in Nova Scotia, 'three splendid clumps of Eels, half a metre in diameter, 30 to a clump, knotted tightly and remaining motionless in the rushes.' Medcof mentions that Eel Balls are sometimes free floating on the surface, which suggests formation with an air pocket or some communal control of air bladders. He says that this behavior occurs before eels 'silver' prior to the spawning migration. The record of Eel Balls in Nova Scotia proves that this behaviour is not confined to the European Eel." ( ...

Coren surveyed students at his University for four years and found that the probability of a left-hander having a car accident was 85% higher; accidents with tools were 54% higher; home accidents were 49% higher; etc. Coren blames these lopsided statistics upon the fact that the world is ordered for right-handers, not that left-handers are innately more clumsy.

All of these hints come from the Pacific and focus on the possible survival of the shark Carcharodon megalodon , a monster relative of the great white shark. Megalodon is thought to have met its demise a million or so years ago. The word megalodon means "big tooth," and indeed the fossil teeth of this monster approach 6 inches in length. Sharks sporting teeth of this size could be as long as 50 feet. Measurements of the manganese dioxide layers accumulated on megalodon teeth dredged up from the seafloor suggest that it might actually have survived the Ice Ages and terrorized the Pacific as late as 10,000 years ago.

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

They don't eat it; they just "like" it! Why, nobody knows. They invade a wide variety of outdoor electrical devices: airport runway lights, stoplight control boxes, household electrical meters, etc. In particular, they favor relays, where they congregate in masses, interfering with current flow and damaging circuitry. The phenomenon is made stranger by the fire ants' complete abandonment of their usual search for food and water (and ankles). They starve in droves and clog up everything. It's a mothand-candle story. Searching for the fatal attractor, researchers have already eliminated magnetic fields, vibrations, and ozone emissions. Apparently, the fire ants "see" something we can't and are smitten by it. (Weiss, Rick; "Ants Get a Transforming Charge," Science News, 136:412, 1989.)

To be sure, corals built the Great Barrier Reef and beavers left their mark on the hydrology of parts of Canada and the U.S .; but termites!? It seems that in southern Africa this industrious insect is responsible for enormous striped patterns of ridges and vegetation bands. These amazingly regular patterns are caused by alternating low ridges and gullies. The ridges are about 2 meters high, up to a kilometer long, and separated by about 50 meters. The ridges themselves are closely spaced termite mounds. Just why the termites choose to build their mounds in long rows is an unanswered question. And how do the termites maintain strict parallelism, especially since they are blind? How could termites in one mound know how their neighbors in the nearest ridge, 50 meters away, are building their mounds? Anyway, the ridges help channel the flow of water and thus the growth of vegetation, giving immense swathes of country a corrugated appearance. (Sattaur, Omar; "Termites Change the Face of Africa," New Scientist, p. 27, January 26, 1991.) Comment. In Australia, the so-called "magnetic" termites build their slab-like mounds so as to minimize the amount of sun-generated heat. From Science Frontiers #74, MAR-APR 1991 . 1991-2000 ...

... Some of the pebbles do indeed resemble humanmade artifacts. (See accompanying sketch.) Most, though, require some imagination. The import of these artifacts, if that is what they really are, comes home when one learns that they come from deposits that are millions of years old! If any of these pebbles are really human-made, anthropology will be stood on its head. Since the present report is the 20th in a series, one can assume that the contributors to Archaeologische Berich ten have amassed incredibly large collections of ancient stones and pebbles that "look like" artifacts. Comment. Similar purported artifacts have been found at the controversial Calico Hills site, California, in Pleistocene deposits that may be 100,000 years old. And don't forget that "Face on Mars"!

What has the position of Mars in the earth's sky to do with an athlete's prowess? No one knows! And certainly no scientist who wants to remain employed will try to find out. Distribution in 18 Mars sectors for sports champions (top) and ordinary people (below). Solid lines are observed numbers; dotted lines, expected numbers. The two peaks in the graph occur at the rise and upper culmination of Mars. We have M. Gauquelin to thank for discovering the Mars Effect. Gauquelin began his research with checking out the claims of conventional astrology. He "found no truth whatever behind certain major tenets of the horoscope, including the alleged influence of the signs of the zodiac, the reality of the astrological 'aspects,' the reported role of the 'houses,' or the prediction of future events." That's the good news, now here's the bad. During his work, he recorded the birth dates of thousands of French men and women who were especially successful in various endeavors, especially sports. These data, easily veri-fied, do seem to demonstrate that the Mars effect truly exists! G. Abell, who was a reknowned astronomer, did ...

Could it, after all, really be artificial? M. Carlotto, writing in Applied Optics, presents the results of his analysis of the photos of this engimatic "face." "The image enhancement results indicate that a second eye socket may be present on the right, shadowed side of the face; fine structure in the mouth suggests teeth are apparent." "Teeth?" This Martian face is becoming too human-like to be an accident of nature! Carlotto also tersely summarizes his impression of the face's features. ". .. results to date suggest that they may not be natural." (Hecht, Jeff; "Computer Does a Double-Take on the Face of Mars," New Scientist, p. 39, July 7, 1988. Also see: Applied Optics, 27:1926, 1988.) In a more light-hearted manner, P. Jones asserts that a second Martian face exists, and that somehow scientists have managed to keep it under wraps. A photo of the second face appears in the August 25, 1988, issue of New Scientist. Jones remarks on the second face as follows: "If faces are what you are looking for, it's reasonably convincing, perhaps more convincing than its better-known sibling. It has symmetry, two eyes ...

Apparently nature -- Mars, at least -- is not cooperating. When the Mariner and Viking spacecraft found no traces of Martian canals, most astronomers "closed the book" on the century-old Martian canals. Percival Lowell and all the other able astronomers who also saw the canal networks were obviously deluded. Wouldn't you know it, those canals haven't gone away! Consider this testimony of I. Dyer: "As staff photographer and observer at Lowell Observatory during the 1960-61 apparition of Mars, I spent several nights scrutinizing the planet's surface through the 24-inch Clark refractor. At instants of steady seeing I saw, and attempted to photograph, an apparent network of fine lines. Unfortunately, I was unable to duplicate clearly what I saw. Still, several of the more visually distinct 'canals' can be traced on my original prints. each is a composite of the finest four to eight images out of 49. Such prints suppress grain, remove artifacts and enhance detail." The canals thus photographed match some of lowell's well, although some of his detail is lacking. (Dyer, Ivan; "Martian Canals ...

Ertel, a German scientist, reported on his inquiry into the so-called "Mars Effect," discovered by Michel Gauquelin. Here are two excerpts from his Summary : "Since 1955 Gauquelin claims to have discovered planetary effects on human births: After rise of a planet and after its crossing of the meridian, birth frequencies of eminent men may either increase beyond or decrease below chance level. .. .. . "In order to find out how clean Gauquelin's database is, the author travelled to Gauquelin's Paris laboratory and checked the files, including data which had been separated from publication, especially athletes' data. Using all obtainable data, Gauquelin's strongest hypothesis was tested, that planetary effects are more pronounced the greater the person's professional success. This claim was objectified with the help of citation frequencies, a sensitive procedure Gauquelin himself had not yet used. The total of 2089 athletes was subjected to this procedure. The results clearly supported Gauquelin's eminence claim." (Ertel, Suitbert; "An Assessment of the Mars Effect," The Explorer, 4:8 , October 1987.) Comment. Is all this simply astrology with scientific trappings? It certainly sounds likt it is! Debunking groups, such as CSICOP, have spent considerable effort trying to disprove the Mars Effect ...
