"At 2304 GMT, Mr. Haney pointed out a bright white object in the sky. It was bearing approximately 360 (T ) at an elevation of about 40 . It was moving rapidly southwards across the sky, leaving a bright trail behind it, like an afterglow. Also trailing astern of the object was a light trail of sparks (possibly large solid particles). The object disappeared behind clouds, bearing about 170 (T ) at an elevation of approximately 35 , and lighting the edges of the clouds. The time taken for the passage was around 20 seconds. It was obviously a very large object, judging from its apparent size as seen from sea level. The impression given was that of an object within the atmosphere, easily showing around a one-penny piece held at arm's length."

... the arterioles but extends to the larger arteries, too. This indicates some degree of specialized adaptation to a diving life. Most animals with a sodium deficiency display an active craving for salt which, when satisfied, disappears. In humans, salt intake has little or no relation to the body's needs. Some Inuit tribes avoid salt almost completely, while people in the Western world consume 1520 times the amount needed for health. In other works, a single African species (assuming humans have an African origin) possesses a wildly different scheme of salt management. Humans are also the only primates to regulate body temperature by sweat-cooling, a system profligate in the use of sodium. Proponents of the Aquatic Ape Hypothesis believe that sweat-cooling could not have developed anywhere except near the sea where diets contain considerable salt, in fact much more salt than the body requires. This article also deals with certain skeletal features of early man that seem to indicate an aquatic stage. For example, the Lucy skeleton has a shoulder joint that indicates that Lucy spent a lot of time with her hands above her head, as she would have if aquatic or treeswinging!

... . The object is usually to encourage a specific predator to eat the host so the parasite can continue its life cycle. A classic example is the lan-cet fluke which infests ants and then sheep. The problem is that sheep don't normally eat ants, giving the flukes a chance to switch vehicles. So, the innovative flukes somehow force the ants to crawl to the tops of plants and lock themselves there with their jaws. The next hungry sheep that comes along has his meal seasoned with ants. The bulk of the present article deals with thorny-headed worms, which are not as endearing as the lancet flukes. These parasites are merely bags of reproductive organs attached to a thorny probiscus, by which they attach themselves to the intestinal walls of vertebrates. Living in a sea of processed nutrients, the worms don't even have a digestive tract. Part of the life cycle of this parasite is spent in arthropods (insects, crustaceans). As with the lancet fluke, the thorny-headed worm's big challenge is getting the arthropod eaten by a vertebrate. In most instances, it alters the behavior of the arthropod in a way that makes it more conspicuous to the predators. For example, infested pill bugs do not hide from birds, as they normally do, and are snapped up. Infested crustaceans move towards the light where ducks consume them. No one knows how a parasite floating in the body cavity of its host can control the host's behavior. (Moore, Janice; "Parasites That Change the Behavior of Their Host ...

... All Issues This Issue Sourcebook Project Sourcebook Subjects The Polyna Mystery "Polyna" is a Russian word meaning "an enclosed area of unfrozen water surrounded by ice." Polynas form for some unknown reason in the Southern Ocean surrounding Antarctica. These transient ice-free "lakes" may cover 300,000 square kilometers, inferring a substantial influx of heat countering the frigid polar temperatures. Although small coastal polynas can be blown free of ice by strong Antarctic winds, the open-ocean polynas are much larger and do not seem to owe their origins to wind. One suggested explanation is that warm subsurface water rises suddenly to the surface, but it takes a lot of heat to keep hundreds of thousands of square kilometers ice-free. The most recent polyna opened up a region of the Weddell Sea for about three years (1973-1976). (Simon, C.; "Polynas Surrounded by Ice and Mystery," Science News, 122:183, 1982.)

(Some fossil animals of about the same age are known in European rocks, but in semiaquatic environments.) 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.

... an apparent reaction to the stampede to climb aboard the extinction-by-asteroid bandwagon, dissenting papers have begun to appear in the scientific literature. For example, Van Valen's list of objections to the hypothesis of asteroid impact at the Cretaceous-Tertiary boundary was reproduced in the last issue of Science Frontiers. Now, in a recent issue of New Scientist, T. Hallam raises still more objections: Tropical plants, mammals, crocodiles, birds, and benthic invertebrates were little affected by whatever happened at the Cretaceous-Tertiary interface. Furthermore, many groups that were extinguished were already well into a decline. Some geologists insist that some of the supposedly synchronous extinctions were probably separated by several hundred thousand years; viz., plankton and dinosaurs. The vaunted iridium anomaly in deep-sea cores is spread through a considerable thickness of sediment. Even after allowing for the mixing of sediments, the iridium-rich layer is thousands of years thick. According to the asteroid scenario, the clay layer separating the Cretaceous from the Tertiary should represent the fallout from impact-raised dust, which would include asteroidal material and a mixed sample of earth rocks. However, in Denmark, the boundary is marked by the so-called Fish Clay, which is almost pure smectite -- a single mineral and not a mixture of terrestrial rock flour. If it wasn't an asteroid impact, why the iridium concentration?

The Society was founded by a group of scientists interested in unrecognized species of animals. "An aquatic creature roughly resembling the traditional 'mermaid,' and sometimes identified with it, is reportedly known through a variety of encounters with natives of Central New Ireland. The ri, as they are called, are frequently sighted by fishermen, occasionally netted or found dead on beaches, and sometimes eaten. Males, females and juveniles are reported, subsisting on fish in the shallow seas around the Bismarck and Solomon archipelagos. It is unlikely that the animals are dugongs or porpoises, both of which are known to, and readily identified by, the natives." New Ireland is northeast of Papua-New Guinea.

The focus of a 1987 paper in Scientific American, by C.H . Nelson and K.R .

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 water suddenly receded leaving Neeah Bay perfectly dry. It was four days reaching the lowest ebb, and then rose again without any waves or breakers, till it had submerged the Cape, and in fact the whole country, excepting the tops of the mountains at Clyoquot. The water on its rise became very warm, and as it came up to the houses, those who had canoes put their effects into them, and floated off with the current, which set very strongly to the north.'" The authors of the present article wonder if the above could be an account of a massive tsunami! They admit that the 4-day recession is inconsistent with tsunami action and that the warm water is hard-to-explain. The height reached by the inundation -- some 400 meters -- is also incredible.

A dull 'strobe-light' effect flashed through a mist, giving the bands a dirty white to gray colouration which was not a 'smooth' colour, but rather grainy in appearance. The bands were about 2 m wide and about 2 m apart and moving at speed. At first it was difficult to discern whether or not the bands were in the water or just above the surface, as no form of reflection or distortion was visible off the hull. In the end, I decided that the effect must be waterbourne if only because nothing was visible in the vessel's wake. "The most intense activity was observed on the starboard side of the ship where the phenomenon appeared to stretch as far as the horizon. At this stage, it did not appear localized, just a mass of high-speed interacting bands of light. The effect is shown in the first sketch.

Multiton basalt columns, formed by volcanic activity, were stacked horizontally, log-cabin style, to form outer walls. The inside was then filled with coral rubble to form a dry surface several feet above high-tide level. Radiocarbon testing finds signs of human habitation at Nan Madol as early as A.D . 500, and the megalithic construction was completed by about 1500." Besides incongruity and a certain bizarreness, Nan Madol does pose several problems: How were the huge, very heavy prismatic columns of basalt quarried and transported? Why was Nan Madol built at all? Why about 1400 AD did the inhabitants stop building their massive ocean-going canoes and begin a decline? (Hanley, Charles J. ...

One way to answer such questions is by turning to old maps and, then, asking the geophysicists if most of the continent's ice cover could have disappeared fairly recently, as some ancient maps are purported to show. C.P . Hapgood, well known for his book Maps of the Ancient Sea Kings, believed that ancient mariners did indeed map Antarctica when those climes were warmer. More recently, J.G .

Now, D.C .Jolly has put the whole problem in perspective in an excellent review. Jolly has studied the data in depth, as indicated by his 51 sources. In his view, it boils down to the fact that the old maps, which people of all persuasions use, are often incomplete and ambiguous. One can read a lot into them.

Muller and D.E . Morris review the evidence tying geomagnetic reversals to the impacts of large bodies with the earth: the tektites and microtektites; the climate changes; the biological extinctions, etc. Then they propose a physical mechanism for geomagnetic reversals: "The impact of a large extraterrestrial object on the Earth can produce a geomagnetic reversal through the following mechanism: dust from the impact crater and soot from fires trigger a climate change and the beginning of a little ice age. The redistribution of water near the equator to ice at high latitudes alters the rotation rate of the crust and mantle of the Earth. If the sea-level change is sufficiently large ( 10 meters) and rapid (in a few hundred years), then the velocity shear in the liquid core disrupts the convective cells that drive the dynamo. The new convective cells that subsequently form distort and tangle the previous field, reducing the dipole component near to zero while increasing the energy in multipole components. Eventually a dipole is rebuilt by dynamo action, and the event is seen either as a geomagnetic reversal or as an excursion."

This perspective has been dubbed 'the selfish gene theory'. While the author acknowledges the insight and creativity that went into the selfish gene theory, it must be pointed out that the idea has not been carried far enough by the geneticists. Where did the genes come from in the first place? Who ever heard of a sea bottom made up of DNA ooze? It is obvious from the fossil data that feces were teeming in the Precambrian oceans well before DNA appeared on the face of the earth, and that feces were therefore the original driving force of life.

While volcanic eruptions form most sea-mounts, these mountains consist of a nonvolcanic rock called serpentinite, and oceanographers are not entirely sure how the serpentinite mountains formed." The theory of plate tectonics has the Pacific plate diving under the Philippine plate along the Mariana trench. It may be that water trapped in the downgoing crust leaks out, rises, and serpentinizes the crust above. This altered rock, being lighter than that surrounding it, may slowly rise through it, eventually forming undersea mountains.

They are not using the directional information of the Earth's field, as we do with our compasses, but small relative differences in the total local field. I arrived at this explanation after a detailed analysis of the records of strandings in Britain, but it has so far been confirmed by two groups working in the U.S . Similar work is in progress in other parts of the world. "The total magnetic field of the Earth is not uniform. It is distorted by the underlying geology, forming a topography of magnetic 'hills and valleys.' My analysis shows that the animals move along the contours of these magnetic slopes, and that in certain circumstances this can lead them to strand themselves. In the oceans, sea-floor spreading has produced a set of almost parallel hills and valleys. Whales could use these as undersea motorways, but might swim into problems when they came near the shore, because the magnetic contours do not stop at the beach. They continue onto the land, and sometimes so do the whales." In addition to stranding because of land-intersecting contours, unpredictable changes in the earth's magnetic field can upset the whales' timing mechanism, causing them to lose their true position on their magnetic dead-reckoning maps.

Ever since this apparent synchrony was recognized a few decades ago, theorists have been vying in generating scientific scenarios, especially some mechanism that would reverse the earth's magnetic field. New entrants in the lists are R. Muller and D. Morris, two Berkeley physicists. Here is how they see it: "A sufficiently large asteroid or cometary nucleus hitting the Earth lofts enough dust to set off something like a 'nuclear winter.' The cold persists long after the dust settles because of the increased reflectivity of the snow-covered continents. In the course of a few centuries, enough equatorial ocean water is transported to the polar ice caps to drop the sea level about 10 meters and thus reduce the moment of inertia of the solid outer reaches of the Earth (crust and mantle) by a part in a million. 'That doesn't sound like much, Morris told us. 'But when we realized that this translates into a full radian of slippage between mantle and core in just 500 years, we began to look seriously at the consequences.' With the moment of inertia of the crust and mantle 'suddenly' decreased, the argument goes, they begin spinning faster than the solid-iron inner core at the center of the Earth.

(Laferriere, Alan P., et al; "Effects of Climate, Tectonics, and Sea-Level Changes on Rhythmic Bedding Patterns in the Niobrara Formation (Upper Cretaceous), U.S . Western Interior," Geology, 15:233, 1987.) Comment. As the rather comprehensive title of this article states, purely terrestrial forces may alter the rhythm. It may be, though, that cyclothem changes reflect actual changes in the earth's orbit resulting from astronomical catastrophism. The Cretaceous saw many geological and biological changes. Cyclothems may tell us more about them. All ten members are never present at one location. The most common sequences are 1, and/or 2, 4, 5, 8, 9 and 10.

... no trace has been found of the first settlers in either North America or northern Australia. In northern Australia one finds groundedge axes at up to 23,000 b.p ., which have no counterparts in the probable catchment area of the first colonizers, Indonesia; while in North America the earlist human settlers used elaborate projectile points, which have no counterparts in the final Pleistocene of eastern Siberia. When and where did such innovations then evolve?" Bodnarik's aolution to this double dilemma assumes that the first colonizers in both cases did indeed come from the north-- -some 40,000 years ago in both Australia and North America - but that their invasion paths were confined to the low coastal areas. Then, as the Pleistocene ended and the ice sheets melted, the sea level rose to obliterate the signs of earliest occupation. Therefore, if archeological digs could be conducted under a few hundred feet of water along the continental shelves, the artifact gap could be filled! (Bodnarik, Robert G.; "On the Pleistocene Settlement of South America," Antiquity, 63:101, 1989.) Comments. Dredges have brought up elephant teeth from the continental shelf of earthern North Ameriva, but we are not aware of any human artifacts. The continental shelf along North America's west coast is hardly a thoroughfare, for it is very narrow. *Very old signs of human activity have now (1997) been found in northern Australia. (SF#110) Also in 1997, Clovistype projectile points were reported from eastern Siberia. The situation ...

Science Frontiers ONLINE No. 61: Jan-Feb 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Terrestrial maria?Those dark patches that constitute the face of the man-in-the-moon are really huge outpourings of lava. Once considered real seas, they are called "maria." Maria like those on the moon also exist on the earth. This is a surprise because terrestrial maria were never mentioned in my college geology courses. But, in those days, the one-mile-wide Meteor Crater, in Arizona, was the largest accepted consequence of celestial bombardment. Deccan basalt flows (also called the Deccan traps) in Western India, shown before the formation of the Carlsberg Ridge and teh splitting off of the the Seychelles. D. Alt and colleagues, at the University of Montana, have identified four large basalt plateaus that might be terrestrial maria: "Notable examples of large lava plateaus that resemble lunar maria include, among others, the Deccan Plateau of India, the Columbia Plateau of western North America, the Parana Plateau of South America, and the Tungusska Basin of Siberia. All consist mostly of basalt lava flows; those on continents include minor quantities of rhyolite, and variable amounts of sediment. All seem to have appeared suddenly, within plates. No consistent context of plate interactions explains them. We suggest that large lava plateaus are indeed terrestrial maria." Alt et al go on to show that these lava plateaus seem to have initiated continental rifts and hotspot tracks where none existed before. ...

... space: Immense quantities of water needed for life-as-we-know-it. The carbonaceous material basic to that same kind of life. (See SF#48.) The seeds of life, a la Hoyle and Wickramasinghe. Energy, as discussed above by Frank et al. Observe that Frank et al are saying that the kinetic energy in the flux of small comets is sufficient to raise a planet's temperature as well as supply water. In this light, exobiologists need not confine their search for extraterrestrial life to planets surrounding warm suns. Somewhere, far from stars, there may be places where comets may raise atmospheric temperatures to where life can prosper! Sunlight, of course, is not needed absolutely, as demonstrated by the profusion of life around deep-sea vents. From Science Frontiers #52, JUL-AUG 1987 . 1987-2000 William R. Corliss ...
