Taking a different tack, R.G . Jahn, at Princeton, has been experimenting with microscopic psychic effects, such as raising the temperature of a thermistor by a few thousandths of a degree or changing the separation of interferometer mirrors by a hundred-thousandth of a centimeter. Quite unexpectedly (at least to the conventional physicist) the mind seems able to cause such changes at will under controlled conditions. The changes are minuscule to be sure, but cause-and-effect is clear-cut according to Jahn. But don't say that psi power has now been scientifically proven. The effects vary from person to person and, for the same individual, from time to time. The fact that one cannot predict the occurrence of the effects has led Jahn to speculate that the phenomena are inherently statistical. (Anonymous; "Dean Justifies Psychic Research," Science News, 116:358, 1979.) Comment. In other words, the effects resemble radioactivity where the behavior of a single atom is unpredictable but en masse the atoms follow the law of radioactive decay.

... published in great detail in the Journal of the Optical Society of America. Ives would have had a more difficult time getting his results published today, for he showed quite clearly that Einstein's Special Theory of Relativity did not correspond to lab results. At the time, such results were not so shocking. Indeed, some philosophers had shown that Special Relativity led to undesirable paradoxes, and experiments by Sagnac and Michelson/Gale had cast additional doubt on this aspect of Relativity. Such experiments by Ives and other key scientists suggested that an ether actually did exist and that it could serve as an absolute reference frame. Another implication was that time was an independent entity unaffected by motion and that the infamous Twin Paradox was a fiction. Ives himself believed his work proved that so-called relativistic effects could be easily explained by phenomena appealing more to the common sense, such as the change of a light source's frequency with motion (over and above the Doppler Effect), rather than revamping space-time concepts. In short, Ives thought he had proved Special Relativity untenable experimentally and an un-necessary distortion of science's worldview. (Barnes, Thomas G., and Ramirez, Francisco S.; "Velocity Effects on Atomic Clocks and the Time Question," Creation Research Society Quarterly, 18:198, 1982.) Comment.

Not only do these heating elements keep the swordfish eye and brain significantly warmer than the surrounding water but they also keep these organs warm and thus more effective during deep dives into the cold ocean depths. (Carey, Francis G.; "A Brain Heater in the Swordfish," Science, 216:1327, 1982.) (2 ) Plants, it seems, developed light pipes long before humans. Certain plant tissues (etiolated or dark-grown) act as multiple bundles of optical fibers and coherently transfer light over distances of at least 2 cm. Optical tests show that these natural light pipes are much more effective transmitters of light than media that simply scatter light. This unsuspected sophistication of Nature's design may require significant revisions in photobiology, which did not allow for such ingenuity.

The moon's influence is understandable, but the planets are too far away for their gravitational fields to influence one terrestrial dust mote. Well, here is one more study showing that the planets (Venus and Jupiter, in this case) do affect the peak electron density in the earth's ionosphere. The effect is most noticeable when these planets are close to earth and dwindles as they swing around to the other side of the sun. The authors are at a loss to explain this effect in terms of gravitation, suggesting that perhaps Venus or Jupiter may instead affect solar activity, which in turn modifies the terrestrial ionosphere. (Harnischmacher, E., and Rawer, K.; "Lunar and Planetary Influences upon the Peak Electron Density of the Ionosphere," Journal of Atmospheric and Terrestrial Electricity, 43:643, 1981.) Comment.

... philosophical background and the superb bibliography must be mentioned. Although Jahn regards his work as only beginning, he does feel that the early results clearly show the existence of non-chance factors in psychokinesis and remote-viewing experiments. For example, interferometer fringes and straingauge readings seem to be changed by the application of "mental forces." But the experiments cannot always be replicated and subjects' abilities are ephemeral. The flavor of the Princeton findings are well put in these sentences from the summary paragraphs: ". .. it appears that once the illegitimate research and invalid criticism have been set aside, the remaining accumulated evidence of psychic phenomena comprises an array of experimental observations, obtained under reasonable protocols in a variety of scholarly disciplines, which compound to a philosphical dilemma. On one hand, effects inexplicable in terms of established scientific theory, yet having numerous common characteristics, are frequently and widely observed; on the other hand, these effects have so far proven qualitatively and quantitatively irreplicable, in the strict scientific sense, and appear to be sensitive to a variety of psychological and environmental factors that are difficult to specify, let alone control. Under these circumstances, critical experimentation has been tedious and frustrating at best, and theoretical modeling still searches for vocabulary and concepts, well short of any useful formalisms."

This cataclysmic event is also blamed (by some, at least) for the apparent sudden biological extinctions recorded on these pages of the fossil record. In this setting, the authors of this paper calculate the effects on the earth of a 10-kilometer-diameter object impacting at about 20/km/sec. Do the theoretical results jibe with the geological and paleontological data? Very definitely. Crater ejecta rich in extraterrestrial material would be blasted to an altitude of 10 km, where winds would insure global distribution. In terms of biological stress, the 10-km projectile would transfer 40-50% of its kinetic energy to the atmosphere, creating a heat pulse that could raise global temperatures 30 C (50 F) for several days. Many large animals might well succumb to such a temperature transient. In addition, the protective ozone layer might be blown away by shock waves and not reform for a decade.

During the following half-century, scientists have been studying this perplexing problem, but it has been the amateurs who have accumulated the bulk of the data. Over 100 reports exist where echoes of radio transmissions were received seconds later at the original transmitting station. Since light travels 186,000 miles per second, any simple radio-wave reflector would have to be well beyond the moon's orbit. A wide variety of natural phenomena (interplanetary matter) and even artificial devices (alien space probes) have been postulated to explain the long delays. Muldrew's article is first of all an excellent summary of the long and fascinating history of this effect. His bibliography is extensive and apparently nearly complete. Muldrew next examines the various ionospheric mechanisms that might cause long delays. The ionosphere is a complex structure with ducts in which radio signals can get trapped. Delays of a second or so might be due to such trapping but the longer delays require some other explanation. Muldrew favors a rather complex interaction between signals from separate transmitters that (theoretically at least) can create a long-lived electrostatic wave that travels in the ionosphere -- a sort of natural memory device. The coded signals could then be read out much later when the proper natural conditions developed. Delays of up to 40 seconds might be possible with this "ionospheric memory."

Observing Io with a spectrophotometer in 1978, F.C . Witteborn et al measured a brightness increase in the 4.7 -5 .4 micron range that was three to five times the brightness at other phase angles. Long a controversial phenomenon, this confirmation of Io's post-eclipse brightening has led to a search for possible explanations. Witteborn et al suggest that the transient flare-up is a complex thermoluminescent effect excited by interaction with Jupiter's magnetosphere, followed by solar heating as Io emerges from the shadow.

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 Astronomy?" New Scientist, 80: 284, 1978.) Comment. The ...

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."

While searching for possible perturbations of the planets due to a tenth major planet or a dark massive solar companion (MSC), he discovered that the perihelia of the outer planets (orbital points closest to the sun) were being disturbed with an average period of 11.2 years. This is almost exactly the sunspot period. This serendipitous finding caused Bagby to wonder whether some common influence was causing not only the sunspot cycle and those perturbations in outer-planet perihelia but also cyclic volcanic and seismic activity on earth. Some correlations indeed do indicate a sun-earth link of some sort. Bagby suggests two possibilities: (1 ) Mutual resonance effects between the planets, (2 ) The effects of a massive solar companion.

Brain-wave tests were even more conclusive. Each personality had its own distinct set of brain waves in response to identical stimuli. In effect, the brain was operating in a different mode for each personality. (Anonymous; "Multiple Personality Not All in the Mind," New Scientist, 98:290, 1983.) Comment.

A preliminary analysis by Michael Mumma, of Goddard Space Flight Center in Maryland, and his colleagues. indicated that processes analogous to optical pumping in laboratory lasers were taking place and led to the coining of the term 'natural lasers.' Now, Deming and colleagues from the Goddard team have taken new observations of emission from Mars and Venus at wavelengths near 10 micrometers. and modelled them to show that stimulated emission -- the effect which makes lasers so powerful -- accounts for up to seven per cent of the total emission.

But, the authors speculate that the sheer size of the natural lasers could make them useful tools in the future for communicating with distant civilizations beyond our own planetary system." The atmospheres of Mars and Venus are almost pure CO2 . The CO2 molecules are excited by the absorption of energetic solar photons; then, thermally emitted photons at about 10 micrometers from lower reaches of the atmosphere collide with the excited molecules, stimulating them to emit another 10-micrometer photon, thus doubling the number of photons.

The usual effect of a parasite upon its host is debilitation, often to the point of death. But parasites have to reproduce, and some settle for the modification of their hosts in ways that improve their chances. Parasites can change the size, color, and even the behavior of their host. The object is usually to encourage a specific predator to eat the host so the parasite can continue its life cycle. A classic example is the lan-cet fluke which infests ants and then sheep. The problem is that sheep don't normally eat ants, giving the flukes a chance to switch vehicles. So, the innovative flukes somehow force the ants to crawl to the tops of plants and lock themselves there with their jaws. The next hungry sheep that comes along has his meal seasoned with ants. The bulk of the present article deals with thorny-headed worms, which are not as endearing as the lancet flukes. These parasites are merely bags of reproductive organs attached to a thorny probiscus, by which they attach themselves to the intestinal walls of vertebrates.

Maddox begins by mentioning the 20-plus-year collection compiled by Professor G.W . Brown, University of London, of life-events that affect the health of outwardly normal people. Typical life-events are the death of a spouse, imprisonment, personal bankruptcy, etc. Everyone seems to recognize -- if only through anecdotes -- that mental states affect health, but how this brain-body link is maintained is hard to pin down.

Morphologically, these waves resemble noctilucent clouds, which are sun-illumined, high-altitude clouds. The infrared waves, however, appear when the sun is well below the horizon. Since these waves are seen only at low angles over the horizon, some geophysicists propose they are the result of a geometric effect produced by viewing a rippled layer of weakly emitting gases in the upper atmosphere. When one looks at this rippled layer just above the horizon, one sees alternating thick and thin sections due to the perspective. The thick portions will appear brighter than the thin sections.

Such flips can of-ten be correlated with climate changes, global ice volumes, sea-floor spreading rates, and deposition of black shales, tektite falls, biological extinctions, etc. The frustrating thing is the lack of clear-cut cause and effect; that is, how these phenomena are linked physically to the geomagnetic field. Part of the problem is that we can only guess at how the geomagnetic field is generated. Let us assume that the earth's magnetic field is created by dynamo action in the planet's fluid core. P. Olson finds analytically that the core dynamo may reverse sign due to fluctuations in core turbulence caused by two competing energy sources: heat loss at the mantle-core boundary and progressive growth of the inner core. In concept, the heat lost at the core-mantle boundary might be linked to climate changes and sea-floor spreading. Taking a different tack, D. Gubbins has investigated the possibility that field reversals are triggered by ice ages and meteorite impacts (tektite falls). The physical mechanism here would be the increase in pressure upon the core, which affects the rate of freezing in the outer core, and thus the power available to the core dynamo.

... phosphorescence lasting some 2.5 hours. The complete report is 6 pages long, with 8 diagrams, so only the highlights can be reported here. As is often the case, this display began with parallel phosphorescent bands (2 sets) rushing toward the ship at about 40 mph. They were 50-100 cm above the sea surface. The bands then changed into two rotating wheels; then a third wheel formed. All three rotated counterclockwise, with their hubs 300, 300, and 150 meters from the ship. The spokes stretched to the horizon. The display ceased for about 20 minutes and recommenced with four systems of onrushing parallel bands, which soon metamorphosed into four rotating wheels. Radar, visible light (from an Aldis lamp), and engine revolution appeared to have no effect on the spectacle. Next, evenly distributed, circular, flashing patches of brilliant blue-white light appeared all around the ship out to a distance of about 150 meters. This system of patches flashed away simultaneously the wheel display. The patches varied from 15-60 cm in diameter, and flashed 114 times per minute. When an Aldis lamp played steadily on the patches, nothing happened. When the lamp was flashed, the whole array of flashing patches disappeared, only to reappear in about 2 minutes. Each patch seemed to consist of worm-like segments 2 cm long, 2 cm apart. The worms were all aligned perpendicular to a vector from the ship. In contrast to the bands and wheels, the worms were located about 5 cm below the surface of the water ...

Science Frontiers ONLINE No. 34: Jul-Aug 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Techno-jinx George Gamow once said of his fellow physicist Wolfgang Pauli that "apparatus would fall, break, shatter, or burn when he merely walked into a laboratory." Some people just seem to have adverse effects on machines. When they appear on the scene, computers crash, copying machines jam, and telephones go on the fritz. Robert Morris, an experimental psychologist at Syracuse University, has been collecting such anecdotes and finds them far from rare. On the other side of the coin, other individuals seem to have phenomenal positive rapport with machinery, like those favored few who can fix anything. Of course, bulging files of anecdotes prove nothing. Many of the stories are likely embellished with each retelling. And some people are singularly clumsy, careless, and ignorant about machines. These types are always pushing the wrong buttons and otherwise mishandling the man-machine interface. Obviously, objective tests are required to determine of there is really anything to this curious business. (Huyghe, Patrick; "Techno-Jinx," Omni, 6:20, May 1984.) Comment.

... person actually is stimulated by a poison ivy-type plant. Similarly, individuals who are viewed as allergic to pollen or house dust may not manifest the allergic reaction when they believe (falsely) that they have not been exposed to the allergic substance. .. .. . "Believed-in suggestions can affect specific parts of the body in very specific ways. Suggestions of being burned can give rise to a very specific irregular pattern of inflammation on the hand that closely follows the pattern of a previously experienced actual burn in the same place. Suggestions that a congenital skin disorder will ameliorate step by step first in one area of the body, then in another, can be actualized exactly as suggested. At least one set of investigators found that suggestions that specific warts will regress can be effective in removing just those warts and not others." In addition to the subjects mentioned in the quotations, the following topics are explored: congenital skin diseases, blisters produced by suggestion, stigmata, mental inhibition of bleeding, fire-walking in safety, control of blood flow and skin temperature, and so on.
