Normal galaxies seem to have masses of about 1011 times that of the sun. The unthinkable assumption suggests that every 108 years or so, these ordinary, unassuming galaxies become supermassive (about 1013 solar masses) for several million years. When the core of a galaxy becomes supermassive, its stars are tugged into tight new orbits. The subsequent switching off of the supermass allows the galaxy to expand outwards again. The author claims to have found just such expansion effects among the globular clusters in our own galaxy. His data are striking and quite convincing. The notorious "missing mass" problem of cosmology disappears with the cyclic supermass assumption because the time-averaged mass of each galaxy will be much higher than that observed in its normal enervated state. Doesn't this sudden temporary appearance of mass violate the laws of physics? No, says the author, physicists habitually assume a superfluid, superconducting vacuum state, which is the ultimate source of all mass-energy, when they develop their theories of fundamental particles. If particle physicists can (and must) evoke such magic, so can astronomers. (Clube, Victor; "Do We Need a Revolution in ...

The significance of argon-36 is that it is supposed to be primordial argon; that is, an argon isotope formed when the solar system was born. Since argon-36 is radioactive, most of the original supply of this isotope should have disintegrated and disappeared over the 4-billion-year history of the solar system. Indeed, the atmospheres of earth and Mars have much, much smaller quantities of argon-36 than Venus. Venus, therefore, may have had an origin different from that of earth and Mars -- either a much more recent birth (such that the argon-36 has not all disintegrated), or an altogether different kind of origin in which more argon-36 was created than was the case for earth and Mars.

Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Man The Scavenger Some 2 million years ago, man's supposed ancestors were meat-eaters. But were they noble hunters with dominion over other life forms? Probably not! The analysis of tool marks on ancient animal bones tells us that human tool marks predominate in regions of the bones where there was little meat, as if ancient humans were dismembering the animals for skins and other products. On the meat-bearing portions of the bones, the tooth marks of non-human carnivores predominate. Where the tool marks overlap the tooth marks of other carnivores, the tool marks are mostly on top of the tooth marks. The gist of the tool-mark analysis is that humans got to the animals second -- after the non-human carnivores. In other words, ancient humans were probably meat scavengers -- opportunists rather than the noble hunters often portrayed. As a matter of fact, one characteristic of a scavenger species is its ability to cover wide areas with little expenditure of energy, like the vultures. Now, human bipedalism is pitifully poor for running down game but great for searching far and wide with minimum physical effort. Tooth-wear studies of ancient human skulls indicate that humans were vegetarians first and meat-eaters second. This situation was suddenly reversed when Homo erectus came along. Then, according to toothwear patterns, there was a shift to a mainly meat diet. This was also the time when ...

The onset of this phenomenon was so rapid, not to say eerie, that the Master was called to the bridge to witness the event.

The most significant of these were what appeared to be Phosphorescent Wheels, which, although they did not seem to rotate, originated from a central hub and spread out rings in rapid succession, forming concentric circles.

Spanos et al begin their article with a neat encapsulation of the status of psychological research into glossolalia: "Glossolalia (i .e ., speaking in tongues) is vocalization that sounds languagelike but is devoid of semantic meaning or syntax. In the Christian tradition this vocalization pattern is associated with the ideas of possession by the Holy Spirit and communication with God through prayer or prophecy. Some scientific investigators conceptualize glossolalia as the product of an altered or dissociated state of consciousness, whereas others view it as symptomatic of psychopathology. "The available empirical data fail to support either of these hypotheses. For example, both ethnographic observations and experimental findings indicate that glossolalia can occur in the absence of kinetic activity, disorientation, and other purported indexes of trance, and that experienced glossolalics do not differ from nonglossolalic controls on measures of absorption in subjective experience and hypnotic susceptibility. Relatedly, the available empirical data fail to support the hypothesis that glossolalics suffer higher levels of psychopathology than nonglossolalics." Spanos et al then go on to detail their own research, in which they tried to teach glossolalia as a learnable skill. First, 60 subjects listened to a 60-second sample of genuine glossolalia. All subjects then tried to speak in tongues for 30 seconds. Some 20% spoke in tongues immediately without further training. The subjects were then divided into a control group and a group that received various kinds of ...

But so far, biologists do not have the slightest notion how such magnetite particles can be turned into a "magnetic sense," which sends the brain information on the direction of the geomagnetic field or, perhaps, draws a magnetic map of sorts. A completely different sort of magnetreceptor is now under investigation, one that humans may also unknowingly possess. It utilizes special photoreceptors that employ an electron-spin resonance process which is modulated by the geomagnetic field. Some of our very sensitive magnetometers use similar phenomena. The biological version of such a receptor would be connected to the brain, as the eye is, and send signals as to the direction of the earth's magnetic field. Sounds interesting, but is there any basis for thinking such a sophisticated gadget could have evolved? It seems that some experiments with newts by J.B . Phillips and S.C . Borland support the idea. The newts were first trained to orient themselves in a certain direction with respect to the geomagnetic field. "When tested under one of four artificial field alignments (magnetic north at geographic north, east, south or west), the newts kept their training directions constant relative to the magnetic rather than the geographic system of reference, but they selected ...

The first enlists the "Life-Saver effect (or "sugar-cube effect"). When Life Savers, sugar cubes, or rocks are fractured, light may flash from their broken surfaces. R.R . Zito, from Lockheed, thinks these flashes occur when energetic electrons are emitted from freshly fractured surfaces. Lunar rocks cracking under stress might very well produce flashes visible from earth. Zito also states that newly fractured rocks emit a curious burst of radio waves in the frequency range of 900-5 ,000 Hertz. (Eberhart, J.; "Does the Moon Spark Like a Life-Saver?" Science News, 136: 375, 1989.) The second explanation of lunar flashes blames them on earth satellites passing in front of the moon. Satellite surfaces can flash like a car's windshield in sunlight, thus simulating a lunar flash. It was just this mechanism that was used to explain the mysterious "flasher" in the constellation Perseus. (SF#53) The May 23, 1985, lunar flash, reported in SF#64, may have been a reflection from a large military weather satellite that was transiting the moon at the time of the flash, say R.R .

The first sighting, on July 30, was quite detailed, and we quote here from the BCCC report. July 30, 1989. Four sketches of Ogopogo from different vantage points. "The focus of the investigation turned to Summerland, and a particularly good vantage point was located at Peach Orchard Beach, Lower Summerland, on July 30. All four members of the investigating team were stationed at various points on the beachfront when, at 3:55 p.m ., a most extraordinary occurrence took place. A large patch of white water materialized close to a headland at the southern end of the beach, drawing the attention of the BCCC observers. It was about 1,000 feet distant at this point, and it was clear that a large animal was swimming in a northerly direction against the prevailing wind and slight swell.

Sure, there are also a few creatures that derive their energy by oxidizing the sulfides dissolved in the 400 water gushing forth from deep-sea vents. We will call them "geochemical creatures" to separate them from the "photosynthetic creatures" we are more familiar with. But, in principle at least, there could also be "Carnot creatures", whose metabolisms depend upon temperature differences like almost all human-built engines. Some bizarre animal, such as a meter-long tube worm, could plant one end on a hot rock surface and dangle the other in cold seawater to reject waste heat from its Carnot engine. Since thermodynamic-cycle efficiencies can approach 60% compared with only 10% for photosynthesis, evolution would have been remiss if it had not tried to evolve "Carnot creatures." For, as D. Jones comments below, Carnot creatures would be adaptable to many more habitats in the universe than photosynthetic creatures, which must have a sun with a very specific electromagnetic spectrum.

In the inner solar system, however, some astronomers are finding "holes" where planets seem to have been ejected by unknown forces. D. Christodoulou, Louisiana State University, found one such "hole" serendipitously. He was studying how the sun and the planets might have condensed from the (hypothesized) cloud of primordial gas and dust. Factoring in gravity, rotation, and magnetic fields, he found the cloud condensing in concentric rings at just the right locations for protoMercury, proto-Venus, and proto-earth. The fourth ring, however, did not correspond to any existing planet, and the position of proto-Mars was off the mark. But the asteroids and outer planets fell rather neatly into place. The implication of these calculations is that some turmoil in the early inner solar system cast out one planet and dislocated Mars. (Hecht, Jeff; "Did Extra Planet Vanish into Outer Space?"

Thus, the patterns of radiohalos help measure the age of coalified wood. A challenge to geology arises because the radiohalos in coalified wood from Jurassic and Triassic formations, supposedly millions of years old, suggest ages of only a few thousand years.

Noting in passing that comets have always been considered bad omens, he postulates that cometary matter may actually contain bacteria and viruses that infect the earth's populace as the planet passes through cometary tails. Recent spectroscopic studies of interstellar matter and comets themselves indicate a richness of life-associated compounds that infers that outer space might well be the breeding ground of simple life. The authors review some of the strange history of epidemic diseases and wonder if their theory of germbearing comets might not satisfy the data as well as the more common hypothesis of random mutation and genetic recombination.

"My wife and I saw a puzzling sight in October 1994, in the Mekong River near Nongkhai, Thailand, during a full moon, in the evening. Lights appeared under the water for a few hundred metres along the Mekong River. They rose from the bottom of the river and floated to the surface, then shot like missiles into the sky and out of sight. They were the size of beach balls, and many flew out of the water every few minutes, surfacing about 10 metres apart. I am told that this happens every year at the same time. Locals say it is caused by a serpent releasing her eggs. Does anyone know of this phenomenon?" A. Pentecost answered. He noted first the similarity of the Mekong phenomenon to the will-o '- the-wisp or ignis fatuus. The usual explanation of ignis fatuus blames the spontaneous combustion of marsh gas. However, the Mekong lights are initially seen under the water where there would not be enough oxygen to support combustion. Pentecost suggested instead phosphorescent bacteria or the "cold flame" of phosphorus vapor which might form through diphosphane decomposition.

J. Gould, who conducts a monthly column in Natural History reviews the sad history of Goldschmidt and his villification by the scientific establishment. Goldschmidt saw the fossil record as woefully inadequate to justify the assumption of gradual evolution of one form into another. Intermediate forms between separate species do not seem to exist in the fossil record and, if they did, they would probably not have been viable creatures. What good is half a wing? Gould believes that Goldschmidt's "hopeful monster" concept will ultimately be dusted off. The key to "macromutation," Gould feels, is not to be found in major gene reorganizations that might produce a whole wing, feathers included, all at once, but rather in changes in the genes that control the development of embryos. Embryos in their early stages are pretty much alike regardless of species. Gould hopes further that the ruling neo-Darwinians will not be so hostile to new ideas and eventually acknowledge Goldschmidt's important work.

Sand Mountain, in Nevada, is noted for its energetic thunderings. (SF#47/214) Manchester, Massachusetts, has its "singing beach." (ESP14 in Anomalies in Geology) But, common as these "sonorous" sands are, the exact mechanism of sound production remains a mystery. D.E Goldsack and colleagues, at Laurentian University, Canada, have reported some advances in our understanding of this classical anomaly. The group discovered that they could make ordinary sand musical by repeated grinding, polishing, and removal of fines. Given sufficient processing, ordinary sand that is merely "noisy" when shaken can be made to "sing." Singing sand has a unique infrared signature: a broad band stretching from 3,700 to 2,800 cm-1 . This is probably due to clusters of water molecules in an amorphous silica layer on the surfaces of the sand grains. Taking a clue from the infrared spectrum, Goldsack et al shook commercially available silica gel in a bottle and heard the familiar tones of singing sand! Their conclusion is that for sand to sing the particles must be coated with naturally (or artificially) created silica gel. (Goldsack, Douglas E., et al; "Natural and Artificial 'Singing' Sands," ...

Because humans "expect" symmetry in nature, it is taken for granted that everything else in the universe is split equally between leftand right-handed molecules. Earth life is just a fluke -- or is it? On September 28, 1969, organic-rich stones fell in Victoria, Australia. This was the Murchison meteorite, and it may carry a message. Over a decade ago, M.H . Engel and B. Nagy reported that the organic molecules in the Murchison meteorite were not split 50:50 between left- and right-handed versions. So contrary to expectations was this finding that most scientists assumed that the analysis was contaminated by terrestrial organic molecules. Now, M.H . Engel and S.A . Macko have refined the analytical techniques and apparently avoided any taint of contamination. Their conclusion: the Murchison amino acids still lean to the left. From all this arise several intriguing possibilities: Life on earth started split evenly between left- and right-handed amino acids, but was nudged to the left by the influx of organic-laden meteorites like the Murchison.

The idea that evolution works only at the gene level has been championed by R. Dawkins, and today it dominates much evolution philosophy. However, this "genetic imperialism" is now being challenged by some scientists who insist that culture also affects an organism's evolution, be it a human or an insect. In fact, it was Dawkins himself who first proposed the term "meme" for the cultural counterpart of the gene. A meme, in other words, is an "element" of culture that can be passed along to progeny by imitation and/or cultural pressures. In reductionist thinking, environmental challenges are met by gene mutations plus natural selection. In meme theory, the same challenges are confronted by cultural changes (meme "mutation") plus natural selection. The meme approach is holistic rather than reductionist and is appealing because it allows us some control over our destiny. There are several phenomena in which some scientists profess to see memes overpowering the genes: Generations of female infanticide have led to more male births than female births.

Debris avalanches are fast cascades of rocks and soil. In Hawaii, both varieties of movement can involve massive blocks of real estate. In the huge Nu'uanu debris slide, stone blocks 6 miles across tumbled 30 miles out to sea. Both slumps and debris slides may create colossal tsunamis. (Tsunamis are miscalled "tidal waves," but they have nothing to do with tides and do not behave like tides or wind-driven waves.)

He was referring, of course, to that "spooky" prediction of quantum mechanics that the mere act of observing subatomic particles affects them. (See: "A Watched Atom Is an Inhibited Atom" in SF#67.) Sheldrake proposes extending the "observer effect" to biology. In effect, he suggests replacing the state of an atom with the state of the neurological connections within the human brain. All this technical jargon breaks down to a simple question: Can a person tell if he or she is being stared at? Before you leap ahead to the next item, which we assure you is not as highly charged with controversy, consider that Sheldrake has conducted thousands of tests that do seem to show the reality of the observer effect in biology. Sheldrake separates starer from staree by a glass window. The staree faces away from starer and is blindfolded. Prompted by a random-number generator, the starer stares or does not stare. The staree responds positively if he feels the starer's eyes locked on to the back of his head. The starees are right more than 50% of the time.

Greek pyramids! On Greek soil, at Hellenikon and Ligourio west of Athens in the Argolid region, are two limestone pyramids that are stylistically very much like those at Giza near Cairo. The big difference is size; the Greek pyramids are only the size of a large room compared to the Great Pyramid's height (with capstone) of almost 500 feet. When excavations were made around the Greek pyramids in the early 1900s, pottery fragments from the Fourth Century B.C . were found, and it was presumed that the pyramids were also constructed then; that is, about the time of Alexander the Great. Recent dating of crystals from internal surfaces of the limestone blocks using thermoluminescence puts the construction times back two millennia. The Hellenikon pyramid dates to 2730 B.C .; the Ligourio, to 2260 B.C . This means that the Greek pyramids were built in roughly the same time frame as the Egyptian pyramids.

The present article reviews the extensive literature on the subject and the longstanding controversy as to whether hypnosis can enhance memory at all. One fact does seem clear, hypnosis does not help subjects recall nonsense data or information without meaning, such as random numbers and words. When it comes to meaningful phrases, sentences, paragraphs, etc., hypnosis does aid recall to some extent. If the words evoke considerable imagery, as poetry often does, hypnosis seems to help recall even more. Finally, the recall of meaningful visual images and connected series of images is helped most of all by hypnosis. In fact, there is some evidence that eidetic imagery, that vivid, near-total recall of images, which is almost exclusively a talent of childhood, can be recovered by mature subjects under hypnosis. There do not seem to be any theories that explain all these effects of hypnosis on memory. (Relinger, Helmut; "Hypnotic Hypernesia," American Journal of Clinical Hypnosis, 26:212, 1984.) Comment. Of course, memory shorn of hypnotic effects cannot really be explained either.

To illustrate, some fungi may be 1,000 years old and extend for 35 acres (15 hectares) and yet possess a single, still unmodified genome. In his review of A. Rayner's new book Degrees of Freedom: Living in Dynamic Boundaries , T. Wakeford writes: "So, like the World Wide Web, a fungal network is decentralized. There is no central region capable of exerting control over the rest of the network. Rayner's own work suggests that the growth patterns of fungal filaments are forged as much by the environment that they encounter as by their genes. He believes that epigenetics, the process whereby opportunities in an organism's surroundings dictate which genes are expressed, is the norm in microorganisms.

The geomagnetic field, the sun, the stars, prominent landmarks, and even odors help guide them across the continents and open seas. But birds are considered highly evolved animals so their sophisticated navigational techniques are not especially surprising. Monarch butterflies, however, are mere insects, with tiny brains (navigation-data processors) and not much in the way of the environment sensors and internal clocks required for long-distance migration. Yet, some of these colorful insects manage to flutter up to 4,000 kilometers from the eastern U.S . and Canada to their wintering grounds in Mexico. How do they do this? S.M . Perez et al have now shown that monarch butterflies are equipped with a sun compass; that is, they chart their courses by noting the sun's changing azimuth.

The sizes of the three qua sars were measured over periods of time by Very Long Baseline Interferometers (VLBIs). In the case of quasar 3C279, the apparent velocity of expansion was ten times that of light. The quasars all have rather large redshifts, indicating great distances from earth, but the lone galaxy displaying "superluminal" expansion has a redshift of only 0.032. This fact suggests that superluminal velocities cannot be employed as arguments against redshifts being cosmological; that is, measures of distances from earth. Therefore, if the redshift is truly a measure of distance (as it seems to be), some astronomical structures (perhaps not matter itself) seem to grow faster than the velocity of light.

Denise Schmandt-Besserat, University of Texas at Austin, believes that these small geometrical shapes (cones, spheres, disks, etc.) were actually symbols used in commerce to indicate numbers and types of commodities (sheep, oil, etc.). Generally less than an inch in size, the clay objects were apparently sealed in hollow clay spheres to make bills of lading as early as 8,500 B.C . This is 5,000 years before two-dimensional clay tablets were introduced for writing. (Anonymous; "From Reckoning to Writing," Scientific American, p. 58, August 1977.) Comment. These clay symbols might be related to the painted pebbles and small carved stone balls found in Europe. From Science Frontiers #1 , September 1977 . 1977-2000 William R. Corliss ...

Sheldrake seemed to show that people could somehow sense when they were being stared at. One particularly sensitive individual was able to do this 90% of the time. But other experiments say otherwise. "A study was conducted to evaluate persons' purported ability to detect hidden observers. Anecdotally, most people (87%) report that covert observation can be detected. A total of 140 college students individually sat in a room with a two-way mirror and videomonitor camera. They were told that they might be observed for any or all of the subsequent 5 min. Participants noted whether they felt a hidden observer watched them during each minute of the 5-min. session. After the session, students reported if a possible hidden observer watched via a two-way mirror or video camera or if they were not watched. Students were unable to detect observation beyond chance."
