These are eliminated by requiring that all experimental results be reproducible by all normal people. Otherwise, every UFO sighting by any individual and each claim of telepathy would be legitimate scientific evidence. Such stringent requirements have made it difficult for parapsychologists to get their experimental results, no matter how carefully acquired, to be taken seriously by mainstream science. How, then, can parapsychology be "legitimized" in the eyes of all scientists? Easy! By redefining science. This is what R.G . Jahn and B.J . Dunne have proposed in a long, philosophical article in the Journal of Scientific Exploration. They define a "neo-subjective" science, which retains the "logical rigor, empirical/theoretical dialogue, and cultural purpose" of present-day "rigorously objective" science, but would: Allow a proactive role for consciousness Be more explicit and profound in the use of interdisciplinary metaphors Permit more generous interpretations of measurability, replicability, and resonance (4 ) Reduce onotological aspirations Permit an "overarching teleological causality.

Frank, at the University of Iowa, had detected dark spots on satellite images of the earth's dayglow. Frank thought that the spots might be due to clouds of water vapor released as small, icy comets hit the atmosphere. P. Huyghe has recently written more about Frank's discovery, his theory, and its reception by the scientific community. "These comets are not occasional visitors, he [Frank] says, like the one that comes by every 76 years and -- lucky for us -- never actually drops in. No, these are very small, cometlike objects that enter our atmosphere at a rate of 20 per minute, he says. These comets, which he believes must contain about 100 tons of water apiece, vaporize on impact with the atmosphere and fall as rain or snow. Now that may seem like one sizeable cold shower, but on a yearly basis he says it's actually only a tiny fraction of the annual preciptation. Then again, over a span of 4.5 billion years, which is about how old the earth is, that's enough water, he says -- trumpets blaring -- to create the oceans." Naturally, such a theory is very disturbing because it runs counter to the widely accepted idea that the oceans were created by the ...

One theory goes like this. It seems that every time an old memory is pulled into consciousness, the brain takes it apart, updates it and then makes new proteins in the process of putting the memory back into long-term storage. The fact that new proteins are made means that the memory has been transformed permanently to reflect each person's life experiences---not the memory itself. (Blakesley, Sandra; "Brain-Updating Machinery May Explain False Memories," New York Times, September 19, 2000. Cr. D. Phelps) Ruminations. This all sounds reasonable, but it assumes that memory is stored in a protein medium of some sort. It is hard to imagine how, say, the multiplication table, can be recorded on a protein "hard drive." Are the bits representing the multiplication table encoded in a line of proteins of different types or in their sequence or, perhaps, their three-dimensional configurations? Does anyone really know what our brain's hard drive looks like? Maybe memory is hologrammic. And when a memory is pulled off the mind's hard drive, how is the information conveyed to the central processing unit, assuming there is one? Is it all ...

Such empirical equations are generally accurate only over a limited region, but this newly discovered relationship holds for almost 50 orders of magnitude. For some unfathomed reason, all astronomical entities spin at rates determined by their masses. Even clusters of galaxies fall into step, slowly pirouetting in intergalactic space to some unknown tune. (Anonymous; "How Things Spin," Sky and Telescope, 64:228, 1982.) Comment.

Leys are supposedly the intentional spotting of megalithic sites along straight lines extending several kilometers. Some alignments occur through chance, but several leys seem statistically significant. The puzzle is why ancient peoples bothered to align their edifices -- assuming they really did. Most professional archeologists believe leys to be figments of the imagination of amateurs. This being so, they must be incensed by the claims made two weeks later in New Scientist. There, stimulated by the earlier report on leys, a retired engineer presented his measurements of the magnetic fields around the Rollright Stones. He maintained that he was able to magnetically detect several converging leys and, in addition, a spiral pattern inside the stone circle. A psychic accompanying him independently perceived the leys and spiral. (Devereux, Paul, and Forrest, Robert; "Straight Lines on an Ancient Landscape," New Scientist, 96:822, 1982.

To illustrate, a chess master can usually recall the positions of all the pieces on a chessboard after a quick glance. But if the chessmen are arranged randomly and meaninglessly, his memory is reduced to near-normal. The gist is that long prac-tice and the application of mnemonic devices can vastly improve anyone's memory and, in consequence, memory prodigies are not really so anomalous. (Ericsson, K.

It must be complete and perfect to work at all. New high-speed photos and related research demonstrate that: "The ejection system of the beetle shows basic similarity to the pulse jet propulsion mechanism of the German V-1 'buzz' bomb of World War II." What the beetle has "evolved" is an intermittent explosive process that fires about 500 pulses per second. The explosive energy comes from the mixing of two separate fluids (hydroquinones and hydrogen peroxide with oxidative enzymes). (Dean, Jeffrey, et al; "Defensive Spray of the Bombardier Beetle: A Biological Pulse Jet," Science, 248:1219, 1990.) Comment. The fundamental question is, of course, how can many, small, random mutations contribute to the development of the mechanisms of the pulse jet, its two fuels, the pumps, the fuel reservoirs, the control system, etc., when only the complete, perfected system has survival value.

One pair are simply extended lower canines, but the second are actually upper canines, the sockets of which have rotated, resulting in tusks that grow through the top of the muzzle and emerge from the middle of the animals's face. The effect is bizarre and startling. The males fight with their dagger-like lower canines and probably deflect opponents' blows with the upper set, thus protecting their eyes.

Sheldrake has found another possible example of "morphic resonance," as he relates in the New Scientist: "Ranchers throughout the American West have found that they can save money on cattle grids by using fake grids instead, consisting of stripes painted across the road. Real cattle grids, known as cattle guards in the U.S ., are usually made of a series of parallel steel tubes or rails with gaps in between, which make it physically impossible for cattle to walk across them.

... Issue Sourcebook Project Sourcebook Subjects Mind Before Life For some years S.W . 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. Two comments here: First, the word "spontaneous" is customarily employed when describing how atoms unite to form molecules and molecules combine into polymers, which then gather into microspheres.

Ordinarily, krypton, being a noble gas, does not enter into any combinations with other atoms - even other krypton atoms. However, P. Lethbridge and T. Stace, at the University of Sussex, have coaxed krypton atoms to cluster together in large, crystal-like clumps with icosohedral symmetry; that is each clump possesses 20 regular faces. The coaxing occurs when gaseous krypton trickles into a vacuum chamber through a hole only 200 micrometers in diameter. The expansion of the gas cools it so that when krypton atmos collide, relative velocities are low, and the weak Van de Waals forces between the atoms are sufficient to hold the clumps together. So far, clumps of 147 and 309 atoms have been detected with a mass spectrograph. One theory of atomic "pack ing" predicts clumps should have "magic numbers" of 13, 55, 147, 309, 561, 923 .. ..

The two assumptions implicit in this classification procedure, which is supposed to mirror actual historical evolution, are: Malarial parasites evolved in parallel with their hosts; and Morphology is a measure of evolutionary relatedness. With modern biochemical techniques it is possible to test these assumptions by comparing the DNA structures of the different malarial parasites. P. falcipa rum, the parasite transmitting the most deadly human malaria, turns out to be more closely related to rodent and avian malaria than the other primate malarias. Therefore, assumption #1 above is in correct in this view. Assumption #2 is also wrong because some species of malaria parasites which are very similar morphologically are quite different DNAwise. (McCutchan, Thomas F., et al; "Evolutionary Relatedness of Plasmodium Species as Determined by the Structure of DNA," Science, 225:808, 1984.) Comment. The article does not draw attention to still another assumption; namely, that similarities are measures of evolutionary relatedness. If this as sumption isn't correct, evolutionary family trees based on bodily structure, which means most of the family trees in the textbooks, may not truly reflect what really happened in the development of life.

The material making up the strata is clearly different from that of the valley walls. After the layers were deposited, they were deeply eroded by some event in Martian history that seems related to the formation of the great outflow channels associated with Valles Marineris. The author of this American Geophysical Union paper concludes: "The morphology and history of the sediments are consistent with deposition in standing bodies of water early in Martian history."

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.

Heckman, of the University of Maryland, has ordained that the apostles of noncosmological redshifts must now recant. He and his colleagues believe that they now have the most convincing demonstration to date that quasar redshifts are of cosmological origin; that is, the larger the redshift, the faster the quasar is receding and the farther away it is. "Availing themselves of the extraordinary new imaging and spectroscopic capabilities of charge-coupled-device (CCD) detectors, they have measured the redshifts of 19 nebulous objects that appear to be companion galaxies of 15 relatively low-redshift quasars. Observing at the Kitt Peak 4-meter telescope, they have determined that, in 18 of these 19 cases, the apparent companion has a redshift very close to that of the quasar. While Burbidge, Arp and their partisans may argue that quasars are so peculiar that they can generate redshifts of unknown origin, this position becomes difficult to maintain for companion galaxies that otherwise look perfectly ordinary." H. Arp and G. Burbidge, chief among those ordered to recant, are not convinced. Arp points to many cases where bridges of luminous material connect high-redshift quasars with low redshift galaxies.

It turns out, though, that rock art seems to be placed intentionally where echos are not only unusually loud but are also related to the pictured subject matter. Where hooved animals are depicted, one easily evokes echos of a running herd. If a person is drawn, the echos of voices seem to emanate from the picture itself! "At open air sites with paintings, Waller found that echos reverberate on average at a level 8 decibels above the level of the background. At sites without art the average was 3 decibels.

Yet despite this, relatively little is known about the nature, extent and functioning of this vast communications network." Some impressive statistics: The Inka Road System runs for more than 23,000 kilometers through Peru, Bolivia, Ecuador, Chile, and Argentina. Generally, the roads were 11-25 meters wide. They were greatly superior to anything built in Europe at that time. One reviewer notes that many of the so-called Inka highways had a non-Inkan origin -- and then leaves us hanging.

The mortality rate for unskilled laborers was three times that of high-level administrators. Part of the disparity is doubtless due to differences in weight-to-height ratio, cigarette consumption, and amount of leisure-time exercise, which are also strongly correlated with mortality rate. But such personal habits tell only part of the story. Coronary heart disease, which accounted for 43% of all the deaths, was much more prevalent among the lower employment grades, even among monsmokers. Childhood nutrition and other "early life factors" also play roles. Nevertheless, a factor-of-three is a whopping difference in mortality rate.

They occur worldwide on the floors of all of the oceans and even some lakes. They are found in shallow waters and at depths of thousands of meters. In diameter, these roughly conical depressions may span 350 meters or more and be up to 35 meters deep. No trivial phenomenon, some pockmark fields exceed 1,000 km2. Like the curious abyssal ridges (SF#97), sea-bed pockmarks are rarely discussed despite their great geological and economic importance. Recent issues of Geology contain three fascinating papers relating to giant sea-bed pockmarks. In Ref. 1, J.T . Kelley et al describe a pockmark field in Belfast Bay, Maine.

Enough high-resolution photos have been taken to prove that these grooves emanate from the large crater named Stickney and run around the satellite to its opposite side where they die out. This suggests that the origin of the crater and the grooves are related. Further, the widest and deepest grooves (700 meters wide and 90 meters deep) are located close to Stickney. On the other side of Phobos, grooves are consistently less than 100 meters wide. Despite these hints of impact origin, the grooves are not quite what one would expect from simple fracture by collision. Some show beaded or pitted structures. Other grooves are composed of irregularly bounded segments. Finally, some of the straight-walled sections seem to have slightly raised rims. Evidently, some internal forces, perhaps stimulated by the formation of Stickney, also played a part. (Thomas, P., et al; "Origin of the Grooves on Phobos," Nature, 273:282, 1978.) Reference.

"A large number of anomalous landforms on Mars can be attributed to glaciation, including the action of ice and meltwater. Glacial landscapes are concentrated south of lat -33 and in the Northern Plains suggesting vast Austral and Boreal ice sheets. Crater densities on the glaciated terrains indicate that the final glacial epoch occurred late in Martian history. Thus, Mars may have had a relatively warm, moist climate and dense atmosphere much later than previously believed." (Kargel, Jeffrey S., and Strom, Robert G.; "Ancient Glaciation on Mars," Geology, 20:3 , 1992.)

The sea was rippled, with a low NW'ly swell and the wind light airs. The visibility was good, with the moon in its first quarter. At first it was thought that there were three lights, one being bright and the other two relatively dim, but as the vessel approached it it was decided that there were only two, one bright and one dim.

In the final analysis, these "pyramids" did not seem to be pyramids at all, at least in the archeological sense. All of this pyramid excitement was precipitated by Rex Gilroy, an amateur Australian archeologist. Well, Gilroy is at it again. This time he claims to have evidence of ancient Chinese visits to Australia -- long before the Dutch explorers and Captain Cook. Although our Australian contacts have warned us about Gilroy, and his "pyramid" evidence has been debunked, his latest data should at least be laid open for inspection, with caveats attached of course. Since China is much closer to Australia than Egypt, and the way is paved with handy islands, early Chinese contacts would not be as anomalous at Egyptian-built pyramids. Gilroy's latest claims are: (1 ) A carved stone head unearthed near Milton, NSW, seems to represent a Chinese goddess. (2 ) An old Chinese record, Atlas of Foreign Countries, describes the north coast of a great land to the south inhabited by pygmies, evidence for which has been found in Queensland. (3 ) A 6th.

Both Australia and the Americas seem to have been peopled late; and both regions seem to have been invaded from the north - according to conventional thinking. Serious anomalies arise because some controversial dates of human occupation from South America and southern Australia are considerably older than those from North America and northern Australia* - at least if we dismiss those North American dates considered as "unreliable" by the archeological establishment. In the Americas, reliable dates older than 12,000 years are found in South America (Monte Verde, Chile); in Australia, all dates exceeding 24,000 years are found along the southern coast.* The "artifact gaps" are therefore clearly established! R.G . Bednarik, in a recent paper in Antiquity, offers a related observation: "It is generally agreed that both regions have been settled from the north, yet 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.

Mimicry is rather common in nature for it often confers some sort of advantage to one or both of the species in the turmoil of evolutionary pressures. Or so the theory goes. Most examples of convergent evolution involve closely related species. In the present case, though, the species are in different phyla. The caddis fly larva builds its snail-like shell by cementing grains of sand together with a silk-like secretion, while the snail's shell is a calcareous excretion. One would expect a strong advantage to be conferred on one or the other species, especially in the matter of predation. Using brook trout as predators, how ever, proved perplexing, for the trout would eat only the snails, avoiding the carbon-copy larvae.

Science Frontiers ONLINE No. 62: Mar-Apr 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Recent Martian Rivers Erode Alba Patera Most of the Martian surface is thought to be more than 3.8 billion years old. This portion is densely cratered from a period pf heavy meteorite bombardment. It is also carved by many channels that are thought to have been cut in ancient times by flowing water, water which quickly escaped into space or combined chemically with Martian minerals. The present atmosphere of Mars, in consequence, contains little water vapor. But some of the Martian landscape, notably Alba Patera, raises questions about the above scenario. The anomalous characteristic of Alba Patera is its relative smoothness and scarcity of impact craters. This Martian real estate is believed to be 2 billion years younger than the rest of the planet. Even so, it, too, is marked by "fluvial" features that resemble stream beds. Question #1 . How did Alba Patera get smoothed out or "reworked"? In other words, what happened to the ancient craters that must have pocked its surface, as they do everywhere else? Question #2 . Where did the water come from to cut Alba Patera's stream beds if all of the Martian water disappeared 2 billion years earlier? One line of thought maintains that "fluvial" does not mean "pluvial," and that Martian water has come from below rather than as rain from the atmosphere. Both fluvial episodes, in this view, occurred when something caused the ...

I.C . Eperon and his coworkers at the MRC Laboratory of Molecular Biology, England, have shown that "human mitochondria did not originate from recognizable relatives of present day organisms." The authors go even further, describing human mitochondria as a "radical departure." (Eperon, I.C ., et al; "Distinctive Sequence of Human Mitochondrial Ribosomal RNA Genes," Nature, 286:460, 1980.) Comment. The inferences above may be far-reaching. Mitochondria are vital components in the cells of the so-called higher organisms. Apparently possessing their own genetic material, they are suspected of being descendants of an cient bacteria that invaded and took up residence in cells. If human mitochondria are radically different, could changes in mitochondria be the source of the purported wide gap between humans and other animals? Did the mitochondria change (" evolve") in existing ancient mammals, converting them suddenly into humans? Or did a new "species" of mitochondria infect terrestrial cells, perhaps coming to earth on cosmic debris, as Fred Hoyle has suggested? From Science Frontiers #13, Winter 1981 . 1981-2000 William R.

Science Frontiers ONLINE No. 50: Mar-Apr 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Too many short-period comets Some comets, such as Halley's , have periods of less than 200 years. Scientists have postulated that these comets, which orbit relatively close to the sun, originally came from the far-distant Oort Cloud on parabolic (non-returning) orbits around the sun. Perturbations by the planets, notably Jupiter, deflected them into the tighter orbits we see today. The problem is that the number of parabolic comets entering the inner solar system from the Oort Cloud of comets (located at the outermost fringes of the solar system) is 100 times too small to account for the existing population of short-period comets. M.E . Bailey believes this discrepancy can be removed if the Oort Cloud possesses a massive inner core of comets. (Bailey, M.E .; "The Near-Parabolic Flux and the Origin of Short-Period Comets," Nature, 324:350, 1986.) Reference. The Oort Cloud of comets is an entrenched part of astronomical dogma. For observations challenging its existence, see our catalog: The Sun and Solar System Debris. A description of this book may be found here .

... optimum levels! Well, the dozen or so other theories that have been advanced to account for whale strandings haven't been much better. M. Klinowska thinks that she has some clues indicating a better theory. First, all whale strandings (in Britain, at least) occur where magnetic field contours are perpendicular to the shoreline. Second, strandings are also correlated with irregular changes in the magnetic field. You will see the significance of these facts after you hear her theory. "Cetaceans use the total geomagnetic field of the Earth as a map. A timer, also based on this field, allows them to monitor their position and progress on the map. 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 ...

Related Amphipods are not only found in Bahamian caves but in marine caves in Bermuda, the Pacific, and the Yucatan Peninsula." (Palmer, Robert; "In the Lair of the Lusca," Natural History, 96:42, January 1987.) Comment.

Science Frontiers ONLINE No. 64: Jul-Aug 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Sheep circles!Britain has been plagued lately with circular areas incised in fields of cereal crops. G.T . Meaden has collected scores of such events, some of which he has published in his Journal of Meteorology. On the theory that one kind of circle might somehow be related to another kind of circle (the same reasoning biologists employ to draw the Tree of Life), J.C . Belcher submitted a most interesting letter to Meaden. "By their very nature sheep tend to be stubborn self-willed animals exhibiting individual characteristics not suggestive of good group co-ordination. For example, when disturbed by a potential predator, a flock of sheep tends to mass protectively in a group of irregular outline, the group being formed of individual groups of small numbers of sheep. When grazing undisturbed, sheep tend to fan out from a given point, sometimes following a dominant group leader. Progress is usually uncoordinated and ragged. In general, patterns presented by sheep en masse are seen to be haphazard, indeed, generally random in nature. If follows that any suggestion of flocks of sheep forming geometric patterns would appear to be highly improbable, since this would call for group coordination only to be found in such as wolves and wild-dogs. In view of this it would appear that certain exceptional observations made on Sunday 21 August 1988 would be worthy of recording. "Out on an afternoon drive M. Belcher ...
