"Sets of concentric rings, similar to those found last summer in British wheat fields, have been discovered in a Japanese subway tunnel. .. .. . "Many sets of concentric rings were found drawn in dust that accumulated on the ground and walls inside the tube. The metro versions of the mystery circles are much smaller -- up to 8 centimeters in diameter -- than the British ones, the largest of which measures scores of meters." Y. Otsuki, a professor of physics at Waseda University, discovered the rings and believes that plasma generated in the air creates them. Subway tunnels, he says, create conditions similar to those in the plasma generators he uses in his fireball research.

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.

To make bark paper, one first takes the inner layer of bark, or bast, from a tree. This material is then thinned, widened, and made flexible by soaking it in water and beating it. The final product retains much of the bark's structure with its interconnecting fibers. Ordinary paper today is also made of wood fibers, but the original fiber interconnections are destroyed in the pulping process. The manufacture of bark paper requires characteristic grooved beaters, specimens of which have been found in both Mesoamerica and Southeast Asia. Were bark paper and the tools required to make it invented independently on both sides of the Pacific, or were they transported across the Pacific by early navigators? If the latter, the flow was probably from Asia to America because the paper-making tools first appeared in Southeast Asia 4-5000 years ago and in Mesoamerica only 2500 years ago. Even so, trans-Pacific voyages 2500 years ago are definitely not part of acceptable archeology. Anthropologist P. Tolstoy, swimming against the mainstream, has surveyed the manufacturing technology of both bark paper and ordinary paper on a worldwide basis. He identified some 300 variable features in the process, 140 uses of the final products, and ...

Let us take the excess-iron problem first. Mercury's density is 5.44 (compared to earth's 5.52), so that it very likely contains much iron. Our moon, which resembles Mercury in size and external appearance, only has a density of 3.34, implying an altogether different origin. In the currently accepted theory of solar-system formation, all of the planets and their satellites condensed from a primordial disk of dust sur rounding the just-formed sun. The planets closer to the solar inferno lost more of their easily vaporized constituents due to the sun's heat. The cooler, outer planets were able to retain large amounts of ices. In this scenario, we would expect Mercury to be rich in iron and rocks. This seems to be the case, but it has too iron to fit the theory. Astronomers have tried to save the theory by supposing that a large asteroid sideswiped Mercury tearing off part of its outer layer of lighter rocks, leaving the heavier iron core untouched. The theory doesn't say what happened to the debris from this colossal collision. As for Mercury ...

The are not the remains of unknown monsters -- they are only dolphin bones! But one mystery has been replaced by several. It seems that there were three different species of dolphins, and they were found at the closed ends of underwater passages that were just a bit larger than the living animals themselves. Why did three different species go into the caves at all? Why did they go all the way to the ends of the closed passages, given their excellent echo-location systems? Pertinent here is the discovery of skeletons and recent carcasses of green turtles in similar situations in underwater caves in Indonesia. Turtles lack the dolphins' echo-location equipment, but they are still excellent navigators. (Molnar, R.E .; personal communication, July 2, 1991. Molnar is a scientist at the Queensland Museum.)

Hybrids bisect these initial paths and would end up in the Alps. Many young birds migrate successfully without help from older birds who have made the trip before. The implication is that migration instructions, perhaps even some sort of map of astronomical or geo graphical references, are somehow written upon the genes inherited from their parents. Just how maps can be coded into gene structure is anyone's guess. (In fact, since the DNA in the genes seems to cody only for protein synthesis, the locations and characters of inheritable maps and other biological instructions are not immediately obvious.) The problem has been exacerbated by recent experiments with German and Austrian blackcaps. These two common European warbler species take different routes to Africa in the winter. The Ger-man blackcaps fly southwest and the Austrian southeast--routes 50 apart. A. Helbig has crossed the German and Austrian blackcaps to see what route(s ) their hybrid offspring would take. Curiously, they favored a route intermediate between those of their parents. The hybrids' route -- bisecting those of the parents' -- would take the hybrids right into the Alps, where survival would be unlikely.

Zoologists have discovered that it taps wood to locate cavities under the surface. Its skills are so well developed that it can tell holes containing grubs from those that are empty. It is the only mammal known to use such a technique." To improve the efficiency of its "percussive foraging," the aye-aye has evolved huge bat-like ears and a highly elongated middle finger on each hand. This specialized finger does the tapping and the big ears relay the nuances of sound to the brain. So sensitive is this specialized form of sonar that the ayeaye can detect grubs 2 centimeters below the surface of the wood. Once a grub has been located, the aye-aye tears into the wood with its forwardcurving, chisel-like teeth. The incisors are remarkable for a primate, for they keep on growing, just like those of rodents. When the grub-containing chamber has been reached, the long, narrow middle finger is inserted and the grub is retrieved. A neat combination of attributes. What is even more interesting is a comparison of the aye-aye with many of the woodpeckers. Many woodpeckers also employ percussive foraging, have special bills for chiselling, and possess very, spiny tongues for extracting grubs ...

If you wish, you can accelerate the substance's demise by touching a match to it; it is packed with potential energy. The substance is methane hydrate, and it is found in prodigious quantities in oceanic sediments. Each cubic centimeter of methane hydrate contains about 160 cubic centimeters of methane at standard conditions; it is a concentrated source of natural gas. In fact, methane hydrate deposits in the world's oceans hold twice as much carbon as all the coal, oil, and gas reserves on land! But methane hydrate may be much more than a future fuel source; it may have been humanity's savior in eons gone by; it may be our future nemesis. You see, methane hydrate is very unstable; changes of temperature or pressure on a global basis can trigger the release of immense volumes of this greenhouse gas from oceanic deposits. For example, when the Ice Ages lowered ocean levels by locking up water in the advancing ice caps, pressures on ocean-bottom methane hydrate lessened and, according to some speculators, released enough gas so that the increased greenhouse heating turned back the Ice Ages.

This notso-well-known geyser is usually very dependable, erupting every 90 minutes, shooting 350 F water 60 feet into the air. However, some 60 hours before the October 1989, 7.1 -magnitude quake in the San Francisco Bay area, the geyser's period suddenly lengthened to more than 100 minutes. After the quake, it settled back into its usual routine. Prior to two other earthquakes, in 1975 and 1984, the clockwork of Calistoga's Old Faithful also ran slow. (Anonymous; "Unfaithful Geyser," Discover, 12:8 , July 1991.) Comment. Since the quake epicenters were many miles distant from the geyser, how is the geyser's clockwork altered?

Benveniste has broken a two-year drought in the "water-memory" or "infinite-dilution" saga.

The crosses are exquisitely wrought and were most likely brought to the Americas by the expedition of Hernando de Soto. Some of de Soto's men, under Adelantado, ventured into what is now Georgia trying, among other things, to Christianize the Indian. The puzzle of the silver crosses is not in their source but in the crude figures and inscription added to one of them. The cross shown in the figure depicts a horse on one side and an owl on the other. The inscription (too small to be read on the figure) is withing the central ring and states: IYNKICIDU, which makes no sense in any known language. This minor mystery was first revealed in the 1881 Annual Report of the Smithsonian Institution . Charles Fort took note of it in his Book of the Damned , where he pointed out that the letters C.

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, ...

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.

Solidifying in flight, these par-ticles fell by the millions. Aerodynamically sculpted Australasian tektite But another type of tektite is also found in Southeast Asia. These are the layered or Muong-Nong tektites, which are not aerodynamically sculptured. They come instead in large, irregular masses, 3-20 centimeters thick, weighing up to 24 kilograms. Their layered appearance is thought to result from flow and stirrings as they solidified in small pools of melted rock and soil splashed from nearby impact craters. These irregular chunks of solidified melt could not have traveled great distances like their streamlined brothers. They lie at most only a few crater diameters from their parent craters. Since layered tektites are found over an area 800 x 1140 kilometers in extent, and they are not far-travelers, Southeast Asia must have been peppered with many small cosmic projectiles 700,000 years ago (the disputed age of the event).

While Time implies that all crop circles are hoaxes, the Science article states that the "really bizarre" circles are hoaxes and that the simpler circles may have acceptable meteorological explanations. Unfortunately, the ridiculing tone of the Time article will probably set back the budding scientific interest in crop circles reported in Science. The real losers, as we shall see below, are those crop-circle experts who assert that they can always detect hoaxes. Essence of the Time article. Two cropcircle hoaxers have confessed. D. Chorley and D. Bower have admitted that they have made as many as 25-30 fake crop circles per year, since 1978, including some of the bizarre ones. All they needed was a 4-foot wooden plank, a ball of string, and a baseball cap with a wire mounted on it for sighting purposes. It was all too easy! And, they assure us, other hoaxers were active in fields at night, too. This is indeed damaging evidence to crop-circle enthusiasts. Time concluded that the admissions of Chorley and Bower have "brought to an end one of the most popular mysteries Britain -- and the world -- has witnessed in years." (Constable, Anne; " ...

Perhaps not!! "This article presents a meta-analysis of experiments testing the hypothesis that consciousness (in particular, mental intention) can cause tossed dice to land with specified targets face up. Seventy-three English language reports, published from 1935 to 1987, were retrieved. This literature described 148 studies reported by a total of 52 investigators, involving more than 2 million dice throws contributed by 2,569 subjects. The full data base indicates the presence of a physical bias that artifactually inflated hit rates when higher dice faces (e .g ., the '6 ' face) were used as targets. Analysis of a subset of 39 homogeneous studies employing experimental protocols that controlled for these biases suggests that the experimental effect size is independently replicable, significantly positive, and not explainable as an artifact of selective reporting or differences in methodological quality. The estimated effect size for the full data base lies more than 19 standard deviations from chance, while the effect size for the subset of balanced, homogeneous studies lies 2.6 standard deviations from chance. We conclude that this data base provides weak cumulative evidence for a genuine relationship between mental intention and the fall of dice." (Radin, Dean I., and Ferrari, ...

G. Morisette and his wife were driving along the road to Sept-Iles, when his wife asked him to stop the car to watch a strange luminous phenomenon. Thinking that it was only Venus or an aircraft, Morisette pulled off the road and got out. To his surprise, it was a formation of five or six meteors cruising leisurely toward the north on parallel paths. This fascinating spectacle lasted about 15-20 seconds -- long as meteor events go. The fireballs disappeared simultaneously. No sounds were heard during or after their passage. (Morisette, Gartan; "Escadrille de Meteores," Astronomie-Quebec , July-August 1991. Cr. F.

When Mariner 10 flew past Mercury in 1974, its camera eye reinforced the baked-cinder model. To everyone's surprise, recent radar images obtained with powerful earth-based antennas, revealed a highly reflective patch at Mercury's north pole. Could it be ice, for ice reflects radar waves well? Quite possibly, for when Mercury's polar temperatures are calculated, away from the sun's direct glare, they plunge to -235 F. This means that some of the water vapor in the planet's thin atmosphere might freeze out in the poles, creating ice or frost caps. Wouldn't Mariner 10 have seen such a remarkable deposit? Not necessarily, for the spacecraft viewed only half the planet and, if the 640 x 300-kilometer ice patch were covered with dust, it could have been invisible to the camera. But it would still be a bright patch on terrestrial radar scopes, because radars see through thin dust layers. So, polar ice is not physically impossible on Mercury, although it is defi nitely surprising so close to the sun. All that is needed is a little water in the planet's atmosphere. Mainstream thinking is that "passing comets and asteroids" might bequeath Mercury some of their H2O ...

Distant quasars are thought to contribute some of this diffuse X-ray flux but, even with recent quasar discoveries, there are just not enough of them to account for the X-rays observed. To make matters worse, quasar X- ray spectra do not match that of the X-ray background either, particularly at very short wavelengths. Superimposed on the general X-ray background are discrete X-ray sources separated by extended blobs of X-ray emitting material. If these blobs are really clumps of clumps of quasars too close to be separated by our instruments, the Big Bang model is at risk, for it cannot account for large, organized assemblages of quasars.

In last winter's first hard frost, I found an odd ice formation in the bowl. Although the weather the previous day had been clement and the water was fluid, we had that night a sharp frost down to about -4 C. The following morning I noticed what appeared to be something sticking up out of the frozen water in the dish. On closer examination, it proved to be a solid 'spike' of ice, ending in an arrowhead. The ice was solid and came out of the side of the frozen water at an angle of about 45 . It was about 9 inches long and solid throughout." (Turner, Judy; "Spooky Spike," New Scientist, p. 54, November 2, 1991.) Two weeks later, the same journal published two radically different explanations of the ice spike. G. Lewis called the spike an "ice fountain" and stated that it is due to the well-known expansion of water as it freezes. R.

Wilder, a member of the Tampa Bay Skeptics, made several pertinent observations during his investigation: "( 1 ) Although the phenomenon is striking when one approaches Spook Hill from one direction, if one gets out of the car and looks back, it is quickly apparent that one's senses have been deceived.

He con tinued as follows: "The events of 1990 and 1991 (totalling about a further 1000 over the two years) certainly present a puzzle. Hoax is beyond doubt in some cases, but it seems very unlikely as a general explanation. Many events have been very large and very elaborate; they have occurred widely about the country (sometimes several on the same night in counties far from each other); there have been very few cases of detection of hoax, despite massive surveillance in the Mariborough/Devizes area, where so many of the events took place; circles (including a dumbbell formation) occurred within visual and radar range of a hi-tech ...

Our experimental study has tried to bring out the existence of a correlation, at a distance, between the physiological reactions of two rabbits from the same litter who had always lived together. We chose photoelectric plethysmography as being the least traumatic method for the rabbits and the one most capable of giving evidence of the physiological reaction specific to stress. Through this method, we studied the coincidences between the outsets of the two rabbits' emotional reactions. Added to the rabbits' isolation through distance, some experiments involved the setting up of sensorial and electromagnetic isolation boxes. We studied the coincidences occurring between the spontaneous emotional reactions of the rabbits as well as the coincidences occurring between the reactions provoked by small stimulae, such as the sound of a bell in one of the boxes. Two series of experiments out of four gave significant results, leading one to think that a conscious or unconscious telepathic link does exist between two rabbits that have close links with each other.

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?

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 acronym SETI is customarily applied to such searches; SETI standing for Search for Extraterrestrial Intelligence. There have been a few exciting false alarms during these listening periods, but most could be attributed to known natural radio sources or manmade interference.

The major exception in the SETI record was the so-called "WOW" (like Egad!) signal picked up in 1977 by a radio telescope at Ohio State University, in Columbus. The bandwidth of the sig nal was narrower than those of most natural sources; there was also some evidence of periodic and drifting features.

When geomagnetic activity around the time of the strongest experimental telepathic dreams was compared to the geomagnetic activity around the time of spontaneous telepathic dreams from the Gurney, Myers and Podmore (1886) collection, very similar (statistically undistinguishable) temporal patterns were observed. Analyses of both experimental and spontaneous telepathic experiences indicated that they were more accurate (or more likely to have occurred) during 24hour intervals when the daily average antipodal (aa) index was approximately 10 3 gammas. When the daily aa index exceeded amplitudes of approximately 20-25 gammas, telepathic experiences became less probable." (Persinger, Michael A., and Krippner, Stanley; "Dream ESP Experiments and Geomagnetic Activity," American Society for Psychical Research, Journal, 83:101 1989.) Comment. It must be added here that mainstream science does not (yet) admit that telepathy exists as a legitimate scientific phenomenon. Nevertheless, there is an immense literature on telepathy and related parapsychological subjects. Once again we have a "shadow science," with ...

Science Frontiers ONLINE No. 65: Sep-Oct 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Samurai And The Ainu Findings by American anthropologist C. Loring Brace, University of Michigan, will surely be controversial in race conscious Japan. The eye of the predicted storm will be the Ainu, a "racially different" group of some 18,000 people now living on the northern island of Hokkaido. Pure-blooded Ainu are easy to spot: they have lighter skin, more body hair, and higher-bridged noses than most Japanese. Most Japanese tend to look down on the Ainu. Brace has studied the skeletons of about 1,100 Japanese, Ainu, and other Asian ethnic groups and has concluded that the revered samurai of Japan are actually descendants of the Ainu, not of the Yayoi from whom most modern Japanese are descended. In fact, Brace threw more fuel on the fire with: "Dr. Brace said this interpretation also explains why the facial features of the Japanese ruling class are so often unlike those of typical modern Japanese. The Ainu-related samurai achieved such power and prestige in medieval Japan that they intermarried with royality and nobility, passing on Jomon-Ainu blood in the upper classes, while other Japanese were primarily descended from the Yoyoi." The reactions of Japanese scientists have been muted so. One Japanese anthropologist did say to Brace," I hope you are wrong." The Ainu and their origin have always been rather mysterious, with some people claiming that the Ainu are ...

The American archeological establishment has been very skeptical about such claims, but now the 12,000BP barrier seems to be collapsing. The turning point may have occurred at a recent meeting at the University of Maine's Center for the Study of the First Americans. The skeptics were bombarded by radiocarbon dates, tools, hearths, and bones from the Monte Verde site in Chile. Some previouslyunbelieving archeologists are now ready to admit dates around 13,000 BP for Monte Verde. (Lewin, Roger; "Skepticism Fades over Pre-Clovis Man," Science, 244:1140, 1989.) Comment. It was only in 1987 that R. Lewin wrote an article for Science entitled: "The First Americans are Getting Younger." Quite a turnaround!! (See SF#55.) Even so, the above Science article did not even mention some other presentations at the Maine conference. But the New York Times did. "At a conference here this week at the University of Maine, Niede Guidon, an archeologist at the Institute of Advanced Social Science Studies in Paris, startled scientists by reporting new results that she said showed the Brazilian rock shelters were occupied by humans at least as long ago as 45,000 years. ...

Science Frontiers ONLINE No. 65: Sep-Oct 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Wood Turtle Stomp J.H . Kaufmann is a zoologist with strong proclivities for wood-turtle watching. Not a very strenuous vocation you say! Be that as it may, wood turtles make up for their lack of speed with some interesting talents. Besides being able to home accurately over unfamiliar terrain, they also know how to "grunt" - not vocal grunting, but a much more curious activity. Kaufmann relates one of his observations: "I came upon an adult male. When I first saw him he was sitting quietly beside a creek, but he soon wandered into a damp thicket of alder, spicebush, and false hellebore. Before disappearing from sight, however, he began to rock back and forth. I followed, trying to stay just close enough to see what he was up to without disturbing him. Fortunately, he did not scare easily, which allowed me to approach within a few yards as he meandered, walking and rocking. First, I noticed that the rocking was caused by short bouts of stomping with the front feet, alternating between left and right. Then he suddenly jabbed his head at the ground and ate something. This behavior continued for a half hour, and several times I caught a glimpse of the prey - earthworms snatched from the surface. I suddenly realized the turtle was 'grunting' for worms!" Turtle preparing to stomp; i.e . 'grunt ...

Science Frontiers ONLINE No. 65: Sep-Oct 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Why the hammer head?You probably thought, as we did, that the function of the hammerhead shark's weirdly shaped head was to separate the eyes and thus improve binocular vision. This is not the case. The visual fields of the hammerhead's eyes do not overlap at all. Each eye presents the brain with a separate, completely different image to integrate. What, then, could be the purpose of the hammer head? No one really knows, but three suggestions are as follows: The head acts as a hydrofoil and gives the heavier-than-water, swimbladderless shark better swimming control. Grooves on the hammer head channel water toward the nostrils, providing "stereoscopic sniffing." The head is a platform for electromagnetic sensors that help locate prey. Stingrays are a favorite food of the hammerhead, and the shark may de-tect them electromagnetically, as surmised by the author of this article in the following encounters: "I have observed great hammerheads swimming close to the bottom, swinging their heads in wide arcs (a motion common, in a lesser degree, to all large sharks) as if using the increased electroreceptive area of their hammer like the sensor plate of a metal detector. Sometimes, these animals would doubleback to scoop up one of several stingrays hiding in the bottom silt. The minute electrical pulse that keeps the stingray's heart and spiracles operating betrays their presence to a hungry ...

Science Frontiers ONLINE No. 65: Sep-Oct 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Fossil Ufos "Geologists have discovered strange disc-shaped features in slate deposits in California. The features, at Yreka, are between 2 and 7 centimetres across and 2 to 4 millimetres thick; some have centres stained with iron oxides. One geologist, Nancy Lindsley-Griffin of the University of Nebraska, has already dubbed the saucer-shaped features, 'unidentified fossil-like objects.' "Geologists discoverd the UFOs in bedding planes of the slate, formed from ocean bottom that was deposited between 400 and 600 million years ago. The objects are puzzling because they lack the symmetry that fossils of living organisms usually display. They are also too large to be the droppings of any creature alive at the time, and do not look like concretions, such as agates, formed by natural chemical processes. Lindsley-Griffin says they resemble very tiny bicycle wheels, with a central core and an outer rim, but with most of the spokes missing.'" One thought is that these features may be fossil jellyfish.

An analogous situation occurs at great depths in the earth's crust itself, as proven by sampling at three deep boreholes in South Carolina. Number of microorganism colony types at various depths at Site P28. The concentration and diversity of microorganisms (mostly bacteria) at depths as great as 520 meters (1610 feet) below the ground's surface are remarkably high. It makes one wonder what will be found even farther down. To illustrate, more than 3000 different microorganisms have been found in the boreholes. Many of the bacteria are new to science. As the following two paragraphs demonstrate, subterranean life consists of many well-adapted microorganisms working together. "The traditional scientific concept of an abiological terrestrial subsurface is not valid. The reported investigation has demonstrated that the terrestrial deep subsurface is a habitat of great biological diversity and activity that does not decrease significantly with increasing depth. "The enormous diversity of the microbiological communities in deep terrestrial sediments is most striking. The organisms vary widely in structure and function, and they are capable of transforming a variety of organic and inorganic compounds. Regardless of the depth sampled, the microorganisms were able to perform the cycling of carbon, nitrogen, sulfur ...
