A nearby binary star, Geminga, has a period of this length. It seems that the 160-minute oscillation of the sun is far too long to be a solar pressure wave, and external forces could conceivably be involved. This article also mentions "the throbbing earth" reported in SF#30, an effect which may result from gravitational waves emanating from the center of our galaxy.

The natives of New Ire-land kill and eat the ri, which they insist is different from the dugong. The team was fortunate to observe a ri from as close as 50 feet as it hunted fish in Elizabeth Bay. The animals was 5-7 feet long, skinny and fast. No dorsal fin was seen, and the tail flukes were mammilian (i .e ., horizontal). The creature surfaced about every 10 minutes. Such behavior is quite unlike that of known cetaceans and sirenians. (Anonymous; "New Guinea Expedition Observes Ri," ISC Newsletter, 2:1 , Summer 1983.)

First, there was the admission that a few small craters, like Meteor Crater in Arizona, just might be of meteoric origin; then, more and bigger craters (astroblemes) were recognized; and, recently, the discovery of the iridium-rich layer at the Cretaceious-Tertiary boundary has made the subject very popular, as evidenced by the following three items: A long, very thorough and scientific review of geological and biological changes caused by meteor strikes throughout the earth's history.

Genuine Azilian pebbles seem to have been carefully selected for size and shape. Most are oval or oblong and may be up to 8 centimeters long, 3 centimeters wide, and one centimeter thick. Over a thousand have been found around Europe. They have been considered primitive art, markers for prehistoric games, and possibly early forms of notation. Claude Couraude has analyzed the markings and concluded that particular combinations of signs recur frequently; the same for certain numbers of dots. There are 16 simple types of signs (dots and lines) but only 41 of the many possible combinations have been found. Evidence supports the existence of some sort of 'syntax.' Couraud speculates that some sort of cyclic notation is involved, perhaps lunar in nature, like some of the markings found on bones from the same general period.

"Plate tectonic processes circulate the entire oceanic crust back into the mantle every 100 million years. Ero sion also removes part of the continental crust, and some of the eroded material may eventually find its way to deep oceanic trenches, where it is also returned to the mantle. This implies that at any given time only about 10% of the crust is at the surface. Much of the continental crust, however, is more than half the age of the earth, so one can infer this part has not recirculated recently." (Anderson, Don L.; "Where on Earth Is the Crust?"

It was travelling eastward and came down over Mrs. Harris's wooden fence landing on the cement porch floor about 3 feet behind us. It gracefully bounced along the cement floor in a straight path covering the 30 foot length of the verandah at a walking pace. It bounced three or four times rising to a height of 18 inches on each occasion. Each time the spherical ball touched the cement it was flattened at the point of contact, and deformed, but it quickly resumed its globular shape when it left the ground. It was not transparent but, rather, like a ball of smoke with glowing 'comma-shaped' electrical 'worms' wriggling about -- sizzling, hissing and flickering. It flattened by 1/4 into the egg shape on each bounce. On reaching the far western end of our verandah it accelerated rapidly and rose at a steep angle of about 45 degrees clearing the apricot tree, wires, and the house next door.

Near Sturgis, Michigan. About 3:00 A.M ., two young women were driving in a semi-rural area. Fog made visibility poor. It began to rain -- a brown jelly-like slime that smeared the windshield. A rotten-egg odor pervaded the area. The car engine stopped, and the two began to walk to find assistance. After 50 yards, they encountered millions of small rays of "lightning" flashing everywhere. They were 2-3 feet long and reached high into the sky. Looking back toward the car, they saw a reddish fluorescent glow with streams of light coming down from the sky to the glowing region. Grass and weeds along the roadside were standing straight up and glowing. Deep-red lines of light were seen dancing on the road. They returned to the car, and it felt hot to the touch! Soon, clouds moved in and the display was over. The authors of this article personally investigated this event within a few days of its occurrence. They found the two witnesses obviously very shaken, but believe that the accounts are fresh and unadulterated. Also pertinent is the fact that a large solar flare had just occurred, and intense auroral displays had been predicted. Also, the two women were apparently the only witnesses of this phenomenon.

Now circumnutation is the result of an "impressively ubiquitous mechanism" in all elongating plant organs. More simply, it is the elliptical weaving motion seen in the tips of growing leaves, shoots, flower stalks, branch roots, etc. In a 4- to 5-day-old sunflower seedling, the ellipse traced is 6-8 millimeters long and takes about 110 minutes. The ellipses result from differ-ential growth in the elongating plants. No one knew whether the force of gravity played a role in circumnutation until some sunflower seedlings were flown on Spacelab 1. Zero-g did not affect circumnutation at all.

Fox, at the Institute for Molecular and Cellular Evolution, University of Miami, has been experimenting with possible precursors of life. So-called "microspheres" are hot items in Coral Gables these days. Fox and his colleagues make microspheres by preparing a heated stew of various amino acids. These amino acids form long polymer chains spontaneously. Then, when water is added and the mixture reheated (or processed in some other way), the polymers organize themselves, again spontaneously, into spheres a few microns in diameter. Each sphere consists of a two-layer membrane with residual material trapped inside. Although thicker, the microsphere membrane is very similar to the lipid bi-layer enclosing normal living cells. The relatively stable microspheres could, in theory, have formed sheltered environments for the evolution of the more complicated parts of living cells. The microspheres absorb sunlight and, with the addition of this energy, display some of the electrical characteristics of biological neurons, like those in the brain. The implication is that some components of "mind" may have existed in the very earliest life forms. (Peterson, Ivars; "Microsphere Excitement," Science News, 125:408, 1984.) Comment.

From western Yunnan and northwestern Hubei provinces come hundreds of recent sightings. Since 1976, four Chinese scientific expeditions have concentrated their attentions in the mountainous, thickly forested Shennongjia region of Hubei Province. So far, though, there are no specimens or even good photos. The major evidence for the existence of the Wild Man consists of anecdotal reports, many casts of footprints (18 inches long), hair (reddish), and samples of feces. The same situation prevails in North America as far as Sasquatch evidence is concerned. Summarizing recent sightings, the Wild Man is a bipedal creature, seven-feet-plus in height, usually covered with reddish hair, possessing human features, with no tail, having the ability to laugh and cry, capable of weaving bamboo sleeping couches, and with no fear of fire. The Wild Man eats fruit and small animals, but has also been known to steal small pigs and corn from farmers.

The Skeptical Inquirer is the perfect "something." In the latest issue, ESP or psi takes it on the chin. J.E . Alcock reviews the last 8 years of parapsychological research. His conclusion: "The past eight years have been no kinder to those seeking compelling evidence about the reality of paranormal phenomena than were the previous eighty: The long-sought reliably demonstrable psychic phenomenon is just as elusive as it always has been." Alcock believes that parapsychology is on the ropes and must grasp at straws. One of these straws is the enthusiastic espousal of those quantum mechanical effects which seem to transcend time, space, and even human comprehension. Alcock contends that the admitted enigmas of quantum mechanics are being unfairly twisted by the parapsychologists. [Parapsychologists and their critics will argue interminably about the applicability of quantum mechanics to psi, ceasing only when someone with powerful, undeniable psi powers comes along -- the equivalent of a UFO landing on the White House lawn.] Meanwhile, Alcock identifies an important characteristic of psi, which is truly anomalous, for it is completely foreign to science as we understand it today.

There may be a trillion stars like our sun in one of these monster galaxies. But it is not the mindboggling number of stars that is anomalous (astronomy dotes on big numbers); rather the anomaly at hand concerns the 11% of the elliptical galaxies that are partly girdled by strange low-luminosity shells. First reported in 1980, these sharply defined shells seem to be composed of still more stars -- vast ellipsoidal sheets of stars emplaced along the long axis of the elliptical galaxy. Some elliptical galaxies have up to twenty partial shells divided between the two ends of the ellipsoid. What is most intriguing is the fact that the shells are systematically arranged. The closest partial shell will be at one end of the ellipsoid, while the second closest will be at the opposite end. The third closest will be just beyond the first closest, and so on. The shells "interleave" or alternate ends as their distances increase. If the alternating partial shells of stars belong to the elliptical galaxy (they seem to, agewise), did the elliptical galaxy shoot the first wave out one end and then expel the second wave out the opposite end? Or did the alternating shells form in situ from the primordial gas and dust that made the galaxy? An-other possibility is that a small galaxy collided with the monster elliptical galaxy, and its constituent stars were ...

One butterfly, Orsotriena medus, masters this situation by changing wing patterns with the season. In the dry season, it is dark brown and inconspicuous; in the wet season, it switches to black wings with ostentatious eyespots and white bands.

In addition to its natural dispersal via its more mobile larvae, the young adult clams have a surprising method of hitchhiking rides on the water currents. Through their siphons they deploy long mucous threads. Water currents pull on these threads just as air currents catch the silken threads of migrating spiders. Given a water current of 10-20 cm/sec, the small clams manufacture and deploy their threads, and off they go downstream.

This civilization produced a distinctive pottery and spectacular gold artifacts. It was obviously a highly advanced culture, technologically and socially. But it was dated at 400-800 AD; and for this period in South American history these accomplishments did not seem out of line. Recently, though, additional evidence of this civilization was discovered beneath a datable volcanic ash. The new dates for this civilization are 600-1 ,500 BC, putting it about 1,000 years ahead of Maya and Inca achievements. The "digs" show further that this culture was frequently beset by devastating outbursts of volcanic activity, which often rendered large areas of land uninhabitable. Rather than suppressing this remarkable culture, Donald Lathrap, a University of Illinois archeologist, says: "Those disasters pushed people from the region and led to upward leaps in social evolution..."

They extend for miles along the hill crests from Berkeley to Milpitas and beyond. Russell Swanson, one of the few persons willing to pursue the walls in the field, estimates that all the walls strung together would run for at least 20 miles. Naturally, time and civilization have destroyed some of the walls, but what remains is most impressive. The searches of property records going back to the Gold Rush and the studies of Spanish mission records give no hints of who built the walls or why. Evidently they are centuries old, possibly prehistoric. Why would anyone build miles of walls from ponderous boulders along miles of ridge crests? They appear to serve no practical purpose. Scientists seem to show no interest in the walls. One even stated: "I don't know of anyone who's come up with a credible explanation.

Kirschvink, of the California Institute of Technology, has plotted the hundreds of beachings of whales and dolphins along the U.S . east coast. He finds that these cetaceans tend to run aground at spots where the earth's magnetic field is diminished by the local magnetic fields of rocks. These coastal magnetic lows are at the ends of long, continuous channels of magnetic minima that run for great distances along the ocean floors. Kirschvink believes that the stranded whales and dolphins were using these magnetic troughs for navigation and failed to see the stop sign at the beaches and ran aground. The mag-netic troughs in this view are superhighways for animals equipped with a magnetic sense. If Kirschvink's theory is correct, the magnetic sensors of the whales and dolphins are extremely sensitive, because the deepest magnetic troughs are only about 4% weaker than the background magnetic field. Magnetite crystals have been found in birds, fish, and insects, where they are thought to contribute to a magnetic sense of some sort. So far, no magnetite has shown up in whales and dolphins.

Surprisingly, two articles on snowflake anomalies have appeared recently. To form at all above -40 F, snowflakes supposedly require a solid seed or nucleus around which ice can crystallize -- or so scientists have assumed for many years. It was long believed that airborne dust, perhaps augmented by extraterrestrial micrometeoroids, served as the necessary nuclei. But cloud studies prove that there are about a thousand times more ice crystals than dust nuclei. Now, some are convinced that bacteria blown off plants and flung into the air by ocean waves are the true nuclei of atmospheric ice crystals. Remember this the next time you tast a handful of snow! (Carey, John; "Crystallizing the Truth," National Wildlife, 23:43, December/ January 1985.) Comment. The possibility that the fall of snow and all other forms of precipitation is largely dependent upon bacter-ia brings to mind the Gaia Hypothesis; that is, all life forms work in unison to further the goals of life. The second item is from Nature and is naturally more technical. After reviewing the great difficulties scientists are having in mathematically describing the growth of even the simplest crystal, the author homes in on one of the fascinating puzzles of snowflake growth: "The aggregation of particles into a growing surface will be determined exclusively by local ...

Almost 6,000 years ago, Neolithic people began erecting a great funeral center and fortress here. When the ramparts were complete, they were visible for miles. The southern and western sides were rimmed by a timber-framed rampart 2,500 meters long. The northern flank was protected by a 1,200meter multiditch outwork. "A Neolithic herdsman who looked up to the hilltop in about 3,400 BC would have seen an impressive site. Crowning Hambleton Hill was a huge defensive enclosure with three concentric ramparts. The inner rampart, the most formidable of the three, was supported by 10,000 oak beams as thick as telephone poles. In the ditch around the ramparts human skulls placed at intervals added an eerie note to the appearance of the fortifications." Such a construction feat must have taken considerable organization and community energy, much like the pyramids then under construction in Egypt. In the absence of stone quarries and with plenty of forests, Hambleton Hill's fortress was simple wood and dirt, but nonetheless very impressive. Even its great size, however, did not save it from conquest and burning. (Mercer, R.J .; "A Neolithic Fortress and Funeral Center," Scientific America,, 252:94, March 1985.) Reference.

Le Roux discovered carvings that had long been concealed. The carvings and the rock itself fit perfectly with the capstone of the Table des Marchands, another famous megalithic monument some 4 kilometers away. Stimulated by this discovery, a third capstone on another monument nearby was found to fit like a jigsaw puzzle piece. The combined result is a huge stela 14 meters high, 3.7 meters wide, and 0.8 meter thick. The total stela would weight about 100 tons. It is decorated on one side with animals (bovids) and other devices. Apparently, this stela once stood near the even larger stela called Grand Menhir Brise or 'er-Grah.' The Grand Menhir Brise is also broken into pieces. Evidently, the period of megalithic tomb building, which probably began about 5,200 BP was preceded by a period when giant, decorated stelae were erected. These stelae were later pulled down and broken up for use in constructing tombs. The civilization that raised the stelae is not well-understood; and one wonders why such impressive monuments were torn down and their engravings concealed. Incidentally, the stela chunk found at Gavrinis weighs about 20 tons and was transported over 4 kilometers across several watercourses. (Bahn, Paul G.; "Megalithic Recycling ...

Conventional radioactive dating had put all of these skeletons at well under 10,000 BP, well within bounds of the Bering Strait migration hypothesis. The early AAR dates were thus at odds with current archeological thinking and, in addition, very encouraging to those who believed that humans occupied North America long before 10,000 BP. J.L . Bada, a proponent of AAR dating, now states that the controversial AAR dates were based on calibration skeletons which had been erroneously dated by radioactive methods. It seems that AAR dating requires an accurately dated reference skeleton. With the reference skeleton dates now known to be incorrect, Bada had to recalibrate his AAR dating scheme. The reference skeletons were therefore redated using a more accurate radioactive technique. All of the incredibly ancient skeletons have now been redated by AAR methods using the revised reference skeletons. The 37,000 BP date now becomes a reasonable 5,100 2000 BP figure. The AAR dating crisis seems to be over. All anomalies have been expunged. (Bada, Jeffrey L.; "Aspartic Acid Racemization Ages of California Paleoindian Skeletons," American Antiquity, 50:645, 1985.)

Two hundred million years seems a bit on the short side for the spontaneous generation of life, although no one really knows just how long this process should take (forever?). The apparent rapidity of the onset of terrestrial life has led to a reexamination of the old panspermia hypothesis, in which spores, bacteria, or even nonliving "templates" of life descended on the lifeless but fertile earth from interstellar space. P. Weber and J.M . Greenberg have now tested spores (actually Bacillus subtilis) under temperature and ultraviolet radiation levels expected in interstellar space. They found that 90% of the spores under test would be killed in times on the order of hundreds of years -- far too short for panspermia to work at interstellar distances. However, if the spores are transported in dark, molecular clouds, which are not uncommon between the stars, survival times of tens or hundreds of million years are indicated by the experiments. Under such conditions, the interstellar transportation of life is possible. But perhaps the injection and capture phases of panspermia might be lethal to spores. Weber and Greenberg think not -- under certain conditions. The collision of a large comet or meteorite could inject spores from a life-endowed planet ...

Menke, directory of the Copernican Observatory and Planetarium, said the ice was probably 6 feet long, 8 inches thick and moving at about 200 mph. 'It's unusual in the fact that it fell from the sky,' said Craig Robinson, curator at the planetarium. 'That does not happen often.' A 13year-old boy was in his backyard Monday with a friend when the ice came 'whirling' from the sky and smashed into the fence about 10 feet away from them." The remainder of the article gives the opinions of some scientists who were contacted about the fall. The director of the observatory thought the ice probably fell off the wing of an aircraft. The director of the American Meteor Society suggested a cosmic origin, providing the ice were pure. An astronomy professor assured everyone that it couldn't be cometary, because the sun would melt particles of ice in outer space.

Three "sludgy" sites have been high-lighted in the recent literature. (1 ) Comets. "Black" comets certainly defy our expectations. Are all those pictures of white, flaming apparitions wrong? Not really. The comets approaching the sun are made visible by sunlight reflected from the gases and dust in the coma and tail, plus some direct emission. However, the heart of the comet, its nucleus, has long been considered a "dirty snowball"; that is, a mixture of dirt and ices. Now it appears that comets are more like "icy dirtballs"! And some of that dirt is pitch black. New measurments of the bare nuclei of comets, using a visual-infrared technique, find that the nuclei reflect as little as 2% of the incident sunlight. They are indeed charcoal black. Comet nuclei, according to W. Hartmann and his colleagues, are colored by a brownishblack primordial organic sludge, and have the appearance of "a very dark Hershey bar."

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.

"Representations of a hare or rabbit on the moon are found in the art of ancient China and in Pre-Columbian Mexico. Mythologies of both areas also place a rabbit on the moon.

Many dinosaur fossils have been dug up in Alaska, northern Canada, Siberia, New Zealand, and Antarctica. Not only were some dinosaurs cold-resistant but, seeing many were herbivorous, they were also able to migrate to more temperate climes as the long days of the polar summers waned. The point here is that the dinosaurs as a clan were very adaptable and should have survived severe environmental stress. (Vickers-Rich Patricia, and Rich, Thomas H.; "The Dinosaurs of Winter," Natural History, 100:33, April 1991.)

Stumps of huge trees 45 million years old dot the now-bleak landscape of Axel Heiberg Island far north of the Arctic Circle. In Antarctica, heaps of 3- million-year-old fossil leaves have been found within 400 kilometers of the South Pole. (Francis, Jane E.; "Arctic Eden," Natural History, 100:57, January 1991.

... Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Crop Circle Roundup Summary of Britain's 1990 crop circles. "Over seven hundred circles were found in Britain in 1990, the earliest in April, the latest toward the end of August. They were spread across thirty counties, including Wales and Scotland, besides which there were numerous good reports of circles from Ireland, Holland, Bulgaria, Japan (at least twenty), Canada (over twenty), the U.S .A . and some other countires. The large British total was made possible because of the cooperation of so many enthusiasts via the nationwide CERES organisation. "As usual for Britain most circles were found in wheatfields, but there were some reports from fields of barley, rapeseed, linseed, and long grass grown for silage. In 1990, as in 1989, Wiltshire dominated the British scene with about 70% of the year's total. This year the leading counties were Wiltshire: over 400; Hampshire: over 50; Norfolk: 18; Devon: 17; Sussex: 16; Oxfordshire: 13; Buckinghamshire: 12; and so on." In his review of the 1990 phenomena, G.T . Meaden dwelt on the Hampshire dumbbell formations. From these many spectacular "circles" we focus on the one at Seven Barrows, Hampshire. Two of the 1990 Hampshire dumbell formations. (L ) Near Seven Barrows; (R ) Near Morestead. "The next system [see figure] was at Seven Barrows, north of Litchfield, Hampshire near the A34 ...

Science Frontiers ONLINE No. 76: Jul-Aug 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The orogrande, nm, site The discovery in a New Mexico cave of numerous stone artifacts, hearths, butchered animal bones and a clay fragment dating back at least 35,000 years could provide proof that the Americas were inhabited long before the generally accepted date of 12,000 years ago, believes Richard MacNeish, research director of the Andover, Mass., Foundation for Archaeological Research. An article in the Baltimore Sun stated: "The most solid proof of human presence earlier than 12,000 years ago may be a piece of a clay pot that appears to have a human fingerprint. "The shard was found in a layer of sediment that has been dated as being 35,000 years old. If confirmed as human, it could be the key to the findings, some archaeologists say." (Chandler, David L.; "Dig Finds Signs of Humans in N.M . 35,000 Years Ago," Baltimore Sun, p. 3A, May 6, 1991.) Comment. It is certain that these discoveries will be disputed -- and rightfully so. Even if they stand, it takes a generation to erase a false paradigm from the roster of science. From Science Frontiers #76, JUL-AUG 1991 . 1991-2000 William R. Corliss ...

Science Frontiers ONLINE No. 76: Jul-Aug 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects New Insights As To The Structure Of Matter Possible "nuclear-molecular" forms of magnesium-24 and carbon-12. Inside the atom. Physicists have long visualized the atomic nucleus as being a shell-like arrangement of its constituent protons and neutrons. Tantalizing experiments suggest other wise. Magnes ium-24, for example, may under some circumstances exist as two carbon-12 nuclei in tight orbit, as in the illustra tion. Even more startling is the "sausage" form of magnesium-24, in which six helium-4 nuclei (alpha particles) are lined up in a row. This "hyperdeformed" state has not yet been detected in the lab, but it demonstrates new thinking among the physicists. (Kenward, Michael; "Are Atoms Composed of Molecules?" New Scientist, p. 21, April 6, 1991.) Comment. Evidently we do not know everything about nuclear physics. Beyond the molecule. We are used to seeing atoms and molecules arranging themselves into mathematically regular crystals. Now it appears that particles consisting of thousands of atoms also spontaneously organize themselves. A.S . Edelstein et al find that molybdenum particles assemble themselves in cubes with two prominent edge lengths: 4.8 and 17.5 nanometers. The larger cubes show up in micrographs as 3x3x3 groupings of the smaller cubes. The smaller cubes each contain about 7000 atoms. (Edelstein, A.S ...

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 Why do flamingos stand on one leg?This profound question elicited a wide range of replies from readers of New Scientist, some of which are worth recording here. W. Smith supposed that because the flamingo has exceptionally long, thin legs that it was difficult for its heart to return blood from its feet. Therefore, by standing on one leg and occasionally switching, the flamingo prevents blood from collecting in its feet. L.J . Los replied with reference to a phenomenon of which we were unaware: "Farm animals are well known for letting sleep be linked to half of their brain at a time. In this way they can maintain a measure of alertness -- even while looking fast asleep. "Flamingos roost upon one of their legs while the other half of their body is in the sleep stage. When the other half of their brain and body earns a rest, they change legs. A leg that is in the sleep stage would not support the bird as a whole." But P. Hardy had the best answer: "Why do flamingos stand on one leg? So ducks only bump into them half the time." (Various authors; "Flamingo File," New Scientist, p. 52, August 17, 1991.)
