About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

It is so dark down there that one would expect deep-sea fish to be blind like many cave-dwelling animals. They are not blind; rather many have eyes of fantastic size and novel construction. An unusual feature of some deep-sea eyes is a layered retina. In the conger eel, five layers of photoreceptors are plastered on top of one another. Yet, experiments with conger eel eyes reveal that only one layer of photoreceptors is active at any one time. R. Shapley and J. Gordon, who carried out these experiments at the Plymouth Lab., surmise that the extra retinal layers are being held in reserve, much like the rows of spare teeth found in sharks' mouths. If so, deep-sea fish are the only animals that have evolved spare stores of visual pigments. (Anonymous; "The Mystery of the Non-Functioning Receptors," New Scientist, 88:366, 1980.) Comment.

Ac-tually, this curious fish has only two eyes, but each is divided in half horizontally; that is, each eye had two separate optical systems, each with its own focal length. The top half is for seeing in the air; the bottom half is for underwater. Thus equipped, Anableps can see prey and predators above and below the surface at the same time and increase its opportunities to get meals as well as escape from its enemies. (Zahl, Paul A.; National Geographic Magazine, 153:390, 1978.) Comment.

... glow and "blind" shrimp In 1988, when the research submersible Alvin was exploring those remarkable hydrothermal vents or "black smokers." Its CCD (Charge-Coupled Device) camera detected a ghostly glow emanating from the vents. Since this mineral-laden water gushing from these cracks in the deep-sea floor exits at 350 -400 C, the simplest explanation of the vent glow is that is is simply thermal radiation from the hot fluid. Indeed, color filters on the camera recorded a spectrum close to that of a 350 C plume. But the deep-sea shrimp camped around the vents have raised second thoughts. The shrimp, only a few inches long, live in the perpetual darkness of the miles-deep vents. They do not need and do not have ordinary eyes. Rather, they sport a mysterious organ on their backs that is connected to their brains by a nerve-fiber bundle much like an optic nerve. This organ is packed with the same light-sensitive pigments found in the eyes of surface creatures. Despite its unusual location on the shrimp, it is an "eye" of sorts. But of what use is it in the Stygian abysses? To find, perhaps, vent glows that betray the presence of chemosynthetic food sources. If this is so, the shrimps' optical organ, which is most sensitive in the blue-green portion of the spectrum, is badly mismatched to the infrared of the vent glow. It is a truism that nature is a perfectionist and would not tolerate such bad design. The eyes of animals ...

... Neumann) machines. Since we can detect neither kind of colonist, we must be the first and only intelligent civilization. Essentially Tipler was criticizing the prevailing notion that, from a statistical point of view, there must be many other civilizations among the numberless stars and galaxies. Tipler's thoughts evoked a richly provocative group of letters, some of which were published in the March 1982 issue of Physics Today along with a closely related article by Ornstein. Ornstein tackled the problem of estimating the probability that intelligent life would evolve on other planets from a biologist's perspective. Whereas some physical scientists have set this probability at about 1.0 , Ornstein inclines toward 10-9 , believing that intelligent life is probably unique to the earth. But concludes Ornstein, the 15 separate developments of eyes among disparate terrestrial organisms may infer some unrecognized directing factor in evolution that would force him to revise his estimate upwards drastically. On the other hand, those 15 eyes might indicate a common, but still undiscovered, eye-possessing ancestor far back along evolution's track. The fossil record might be mute on this matter because eyes are soft tissues that are rarely preserved or perhaps because many eyes were jettisoned because the organisms didn't need them, as cave dwellers are wont to do with surprising rapidity. Some of the letters responding to Tipler questioned whether an intelligent civilization would be stupid enough to build self-reproducing von Neumann machines for galactic exploration. Wouldn't it be far more fun to go in person rather than by proxy? And, some pointed out, von ...

These are the rays that penetrate to the greatest depths in the sea. This adaptation to blue light means that deepsea fish have evolved visual pigments different from those of surface fish and land animals. Visual pigments are complex chemical compounds, and one must suppose that many, many random mutations took place before deepsea fish were able to manufacture visual pigments different from their relatives living near the surface. (Or did deepsea fish come first?) But there is more to this story. Many dwellers in the black abysses generate their own light. They sport bioluminescent organs so they can be seen by others of their own species and, in addition, illuminate prey for easier capture. In another remarkable example of evolutionary convergence, these bioluminescent organs emit light spectrally matching the eye sensitivity of deepsea fish! So far, though, this story is not any more amazing that many others woven into evolution's fabric. But suppose that a deviant species of deepsea fish upset this cosy status quo by evolving visual pigment and bioluminescent organs operating in a part of the electromagnetic spectrum that other deepsea fish could not perceive. It would be as if this species had radar but the others did not! Well, three genera of dragon fish do ...

The outward manisfestation of time-keeping is in the precise timing of the colony's nomadic phase of 15 days (during which larvae are growing) and the 20-day stationary phase (during which pupae develop). The queen's egg-laying also conforms with this schedule. Raids into the rain forest occur in both phases. Perhaps more remarkable is the systematic orientation of the raids in the stationary phase. These raids are separated by an average 123 , as diagrammed. This scattering allows time for new prey to enter the previously raided areas. But how does the colony determine direction in the dense rain forest? Probably from polarized sinlight, thinks Franks. But here we have a problem: each army ant, instead of having multi faceted compound eyes like most insects, has just a single facet in each eye. "The mystery is how the colony can navigate with each of its workers having such rudimentary eyesight. In my wildest dreams, I imagine that the whole swarm behaves like a huge compound eye, with each of the ants in the swarm front contributing two lenses to a 10- or 20-m wide 'eye' with hundreds of thousands of facets." (Franks, Nigel R.; "Army Ants: A Collective Intelligence," American Scientist, 77:139, 1989.) Comment.

I noticed the crescent of the waning moon appeared as a double crescent. My eyes kept trying to resolve it into a single image, but it wouldn't resolve. I then looked at several other light sources (radio tower, porch light, & street light) and determined that my vision was probably fine, as these objects appeared as single images. Looking back at the moon, it still appeared as a double image. I covered the right eye and I still saw a double image. I did the same with the left eye and got the same results. I then held out my right arm and extended my thumb to cover one crescent. I saw only one image that way. I moved my thumb and the image was again doubled. I concluded that I was viewing refracted images of the moon. "Conditions prevented continuous observation, but I was able to return approximately every five minutes.

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 primate-like eye-brain system of the fruit bats suggests two possibilities: 1. Primitive bats first developed flight and then the fruit bats developed their primate-like eye-brain systems through "convergent evolution"; or 2. The fruit bats inherited their eye-brain system from closely re lated primates and then developed flight through "convergent evolu tion." R.D . Martin, a physical anthropologist and author of this article, has reviewed the morphological characteristics of the fruit bats and primates. On this basis, he doubts that the fruit bats are pri-mates. Furthermore, molecular studies are also negative. Therefore, possibility #1 above is the more likely one. (Martin, R.D .; "Are Fruit Bats Primates?" Nature, 320:482, 1986.) Comment. In either case, #1 or #2 , we must acknowledge convergent evolution and the likelihood that some subroutine in the genetic code repeats itself in divergent species. Speculative as always, we must ask if the genetic instructions for human or even superhuman intelligence do not reside dormant-for-now in other species. Reference.

Cats and some snakes have a vertical shape yet horses and goats have a horizontal one. What is the reason behind the differences and, more importantly, how do the different shapes affect how animals actually see things? The answer for the vertical slit is that it improves an animal's focus in the direction perpendicular to the slit. Thus, cats and snakes hunting close to the ground can better detect their prey over a wide horizontal field. But how about the horses, goats and other grazing animals that must keep their eyes open for predators across a wide horizon? Pupils with horizontal slits would seem to defeat this purpose. Ah, but when they lower their heads to graze, their vertical pupils become horizontal. Simple! (Anonymous; "Eye to Eye," New Scientist, p. 85, December 11, 1999.) Comments. But puzzles remain, otherwise we wouldn't address this subject. (1 ) Some snakes have round pupils (as in the illustration) having apparently been subjected to different environmental forces; (2 ) Of all the 9,000+ species of birds, only the skimmers own pupils with vertical slits.

With sophisticated terrestrial and satellite-borne instruments, they have detected gamma-ray, X-ray, and infrared bursters. The visible portion of the spectrum has been neglected because of the slow development of sensitive, high-time-resolution detectors capable of monitoring large areas of the sky. Of course, the human eye is an excellent instrument for searching for optical bursters, but professional naked-eye astronomers are few and far between nowadays. It has fallen to amateur astronomers to pioneer this field, as first mentioned in SF#39, where we introduced those optical flashes seen in Perseus. At last, the professional astronomers are taking more interest in this class of bright, unexplained flashes in the night sky. Those amateur astronomers, with their "primitive" instrumentation, have actually had a paper published in the highly technical Astrophysical Journal. Their abstract follows: "Between 1984 July and 1985 July, 24 bright flashes were detected visually near the Aries-Perseus border by eight different observers at a total of 12 sites across Canada. One flash was photographed, and another was seen by two observers at different locations. Their duration was usually less than 1 s.

"The image enhancement results indicate that a second eye socket may be present on the right, shadowed side of the face; fine structure in the mouth suggests teeth are apparent." "Teeth?"

The universe of voles -- small, mouse-like rodents -- is one of odor. They communicate with one another and navigate through their world of grass and vegetation by laying down trails of scent-laden urine. The world of kestrels -- eaters of voles -- is one of sight. Now, voles are hard to see in the grass far below a hunting kestrel, but evolution has come to the aid of the kestrels by giving them the capability to see in the ultra-violet portion of the spectrum. Can it be only coincidence that the urine trails of the voles happen to absorb ultra-violet light strongly? Kestrels can see these trails as dark streaks in the grass below and zero in on their prey. Finnish scientists, led by E. Korpimaki at the University of Turku, have demonstrated the above ultraviolet connection by somehow acquiring enough vole urine to lay out artificial trails in voleless areas. Sure enough, hunting kestrels were attracted to the experimental site and searched and searched the artificial vole highways -- volelessly. (Aldous, Peter; "Vole's Urine Is Their Downfall," ...

Such mammals have bichromatic vision and discern colors rather well. Humans and the other primates are blessed with trichromatic vision, for their eyes have cones that register red light. Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it is easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on ...

The flat sides and silvery scales of this species make highly efficient mirrors. These fish have learned how to maneuver their bodies so as to reflect bright flashes of sunlight directly into the eyes of their opponents. These intense bursts of light are often enough to burst blood vessels in the eyes of the target fish -- sometimes even stunning it. Pairs of Amazonian angel fish have been observed flitting about in "light-fights" as they attempt to zap each other and avoid optical counterattacks. (Anonymous; Creation/Ex Nihilo , 21:7 , March-May 1999. Attributed to Sydney Morning Herald , October 13, 1998.) Comments.

They have also had a lot of fun and some success in devising algorithms (mathematical methods) for the generation of seashell markings. In fact, our title above is also the title of a new book by H. Meinhardt, which suggests how a suite of simple biochemical processes can create those shells coveted by collectors. Meinhardt has devised equations that describe chemical factors that turn pigment-generating cells on and off. In its simplest form, a mathematically modelled seashell is a two-dimensional sheet that grows along only one edge. Cells on this edge may or may not secrete pigment depending upon chemical "influences." B. Hayes describes how this sort of model operates: The triangular pattern on Cymbiola innexa suggests the presence of a "global control element" that turns the pigment-secreting cells on and off in the correct order -- something like a computer-controlled loom! "Given this generating mechanism, some shell patterns are easy to understand. A series of vertical stripes -- that ...

Instead of ending with an exclamation point, a question mark would have been more appropriate. The Perseus Flasher, a recurring flash of light in Perseus described in SF#39 and #49, is a topic upon which astronomers also wish to "close the book." So, we must ask ourselves how accurate the above title is. Photographic records of the Perseus Flasher site show no flashes at all in 3,288 hours of monitoring. In fact, a Harvard plate, which was being exposed at the same time that a 0-magnitude flash was reported by naked-eye observers, revealed nothing! The passages of some artificial satellites through the Perseus site have been correlated with naked-eye-observed flashes, suggesting that the flashes are only sun glints. One meteor observer, N. McLeod, claims that there is a background level of flashes from other parts of the sky which can also be attributed to satellite glints. The Sky and Telescope item concludes: "So the mystery is solved!" (Anonymous; "The Perseus Flasher: Mystery Solved!" Sky and Telescope, 73:604, 1987.) 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.

Basically, the hypothesis maintains that the forms of things (from crystals to life forms) and the behavior of organisms is influenced by "morphic resonance emanating from past events." Convergent evolution, wherein human eyes closely resemble squid eyes, might well be explained by the hypothesis. Sheldrake has been testing his idea in various ways. One experiment involves the accompanying illustration containing a hidden image. Once the solution of this illustration is learned, it is hard to forget, but few people see the answer right off. The hypothesis of formative causation insists that once one or more persons learn the drawing's secret, the easier it will be for others to see the solution. Actual tests consisted of broadcasting the illustration and its solution (that is, the hidden image) on English television combined with before-and-after checks elsewhere in the world outside TV range. The results strongly supported the hypothesis, for it was far easier for people outside England to identify the hidden images after the broadcast.

The precise source of the visible light is still in doubt as is the identity of the stimulus causing the glowing ripples. Peterson has noted some correlation between the ripples, both visible and infrared, and the lunar high tide in the atmosphere. Gravity waves could thus be the stimulus creating the ripples.

They can then finally "close the book" on the phenomenon. Sometimes, though, the book is slammed shut prematurely or unjustifiably. Also, as it often happens, closing one book opens another and the new one is even harder to close. Below, we present three examples where finality (closed books) seems to be proclaimed too quickly. On occasion, the night side of Venus (which goes through phases like the moon) seems to glow softly and subtly. For some 350 years, keen-eyed observers have seen this phenomenon through their telescopes. Nevertheless, the effect is so elusive that many astronomers doubt its physical reality. Additionally, it is easy to doubt the existence of the ashen light because good explanations are as elusive as the light itself. During the past decade, two scientific nails have also been driven into the ashen-light coffin: Spectrographic studies of the upper atmosphere of Venus do detect some nighttime air glow, but it is much too weak to account for the abundant telescopic observations from earth. The Cassini spacecraft did not detect any high-frequency radio noise typical of lightning when it passed close to Venus in 1998 and 1999. This put an end to the surmise that the ashen light was due to rapid, widespread lightning occurring deep inside the planet's ...

Photoreceptors are sensitive to light but do not produce images. They are found in many groups of animals. Even humans possess photoreceptors besides their eyes; specifically, in the pineal gland and, perhaps, the knees. (SF#116, SF#117) The pineal gland (our "third eye") may have registered photons at some stage in our evolution, but it is now useless or adapted to other purposes. The arthropods, however, still find photoreceptors useful. Crayfish have them on their abdomens, where they initiate an escape response when illuminated. Additionally, the blind shrimp that collect around the glowing deep-sea vents have photoreceptors perched on their backs, presumably to guide them to their prey located around the luminous vents. Recently, the Japanese yellow swallowtail butterflies were discovered to sport photoreceptors on their genitalia.

Specifically, individuals can be commanded to appear and the action controlled to please the dreamer. As Keith Hearne, a dream researcher, remarks with tongue-in-cheek, the entertainment possibilities are endless if lucid dreaming could be induced in everyone! Lucid dreams are so real that the dreamer will sometimes believe that he has awakened and answered questions from the researcher, when nothing like that has happened. Lucid dreaming occurs only during periods of REM (Rapid Eye Movements) sleep. The lucid dream-er, however, can signal the dream researcher that lucid dreaming has begun with agreed-upon eye movements and changes in the rate of breathing.

What made the dark object an even stranger sight was a considerable number of "Xmas candies", all hanging down from its underside 15 to 20 centimetres long and "sparkling", which means changing brightness with an emission of sparks at the same time.

Are life forms in the vicinity of the vents employing photosynthesis? We don't know yet, but some bacteria do photosynthesize. Might not life and perhaps photo synthesis, too, have originated at the vents rather than on the planet's surface? This is an attractive possi bility, because very early in the earth's history the surface was con tinually blasted by meteorites, comets, etc. -- a very inhospitable place. The above questions are so fascinating that we might easily neglect another vent anomaly; one involving those blind shrimp. Like many cave creatures, these shrimp dispensed with eyes long ago. This being so, how do they find the vents, those rich oases of energy and food on the otherwise bleak sea floor?

A latticework of delicately beveled edges, gleaming like polished gold, framed with diamonds. The whole array shimmered before me in perfect amber and gold splendor for what must have been several seconds." This kind of geometrical visual experience occurs rarely to some people during "twilight" states just before falling asleep or waking. Direct pressure on the optic nerve produces similar geo meters' delights; so can drugs, fever, sleeplessness, and other altered states of consciousness. Migraine headaches, too, are often presaged by floating, semicircular fields of closely spaced parallel lines or bars arranged in zigzag patterns.

Photomultipliers in the Fly's Eye telescopes 100 kilometers southwest of Salt Lake City recorded the havoc wrought in the upper atmosphere by the most energetic cosmic-ray particle ever measured. When this tiny subatomic particle slammed into air molecules, the ensuing debris caused the surrounding atmosphere to fluoresce. The amount of light produced indicated that this cosmic ray had an energy of 3 x 1020 electron volts -- that's equivalent to the energy of a bowling ball dropped from waist level. Now that's a lot of energy for a subatomic particle! Because cosmic rays normally lose energy as they collide with photons in their cosmic wanderings, astrophysicists believe that "the big one" had to have a recent, nearby origin in order to still be so energetic. But no one has any idea where it could have come from or how it might have acquired so much energy. Somewhere out there in nearby space there may be a natural particle accelerator orders of magnitude more powerful than our biggest earthbound atom smashers. (Anonymous; "The Deepening Mystery of Cosmic-Ray Origins," Sky and Telescope, 87:12, May 1994.) Comment. Actually, the source of "the big one" need not have been nearby and recent. All anomalists will recognize that this is an assumption based upon the particle ...

Science Frontiers ONLINE No. 106: Jul-Aug 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Looking Up Into A Tornado Funnel January 21, 1992. Near Cripple Creek, Colorado. Shortly after 2 PM, while fishing at Skagway Reservoir, D. Mc Gown spotted an ominous cloud formation developing in the west. A horizontal, black cloud rolled toward him. Suddenly, it lifted to reveal a huge, twisting funnel advancing directly at him. He threw himself to the ground, but got a good look up into the interior of the funnel. "The outside of the tornado was spinning so fast my eye couldn't follow it, but the inside was rotating almost lazily. I could see a thousand feet up inside it. Tiny fingers of lightning lined the hollow tube." Passing over him, the funnel bounced across the lake, ripped up some trees, and was gone. (McGown, Dennis; "Letters," Time, 147: 8, June 10, 1996) Comment. The "tiny fingers of lightning" are of great interest to anomalists, because most meteorologists deny that electricity plays any part in tornado activity. Of course, there is often plenty of ordinary lightning in the accompanying storms. An observation very similar to McGown's occurred in Kansas, in 1928. (GLD10-X2 in Lightning, Auroras.

April 17, 1995. Strait of Hormuz in the Persian Gulf. Aboard the m.v . British Reliance, enroute Fujairah to Kharg Island. Observers: the Master and Second Officer. "At 1525 UTC whilst in the westbound lane of the Traffic Separation Scheme and shortly after settling on a course of 270 , a small amount of blue phosphorescence was noticed in the sea waves ahead (the swell being very low). Suddenly, the wind appeared to blow quite strongly, swirling around the vessel and then for as far as the eye could see and all around the vessel, phosphorescent cartwheels of bright-blue light began forming. The bands of light were roughly 30 cm thick while the maximum diameter of the wheels was 15-18 m. "Their direction of movement seemed random and they were spinning at high speed, some chasing each other, others spinning in opposite directions next to each other, see sketch. "Whole groups dumbbelled around each other, all spinning in apparently random directions. The display lasted for about 18 minutes before petering out." A comment by P.J . Herring of the Southampton Oceanography Centre followed. "A quite extraordinary account of phosphorescent wheels occurring in one of the places where they are most often seen. In the 200, or so, cases of this phenomenon reported in the last 100 years, ...

The bait, which is part of the anglerfish's body, has fins, a tail, and black spots for eyes. The waving about of the bait attracts predatory fish close enough for the anglerfish to snap them up. The authors surmise that the anglerfish evolved this realistic bait (and rod and reel) in order to save energy in acquiring food. (Pietsch, Theodore W., and Grobecker, David B.; "The Complete Angler: Aggressive Mimicry in an Antennariid Anglerfish," Science, 201:369, 1978.) Comment.

Science Frontiers ONLINE No. 107: Sep-Oct 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects More Sparks On The Beach Sharp eyes often pick out unusual phenomena in very usual places. From California, A. Hastings writes: "I also had an experience with 'Sparks on the Beach' as in SF#104/4 . This was on the Pacific Ocean Beach at San Gregorio, south of San Francisco, several years ago. I was walking on fairly wet sand, just above the tide line. As I stepped, the sand around my feet lit up with small bright dots of phosphorescence. I would not have said that the color was blue, but it could have been like blue-white, like the star Rigel. I found that if I stepped hard or stamped my foot, the lights flashed brighter and the lit area went out farther from my foot. I could see the movement expanding out. After a stamp or two, they did not light up as much. I assumed that this was caused by some organism that lit up when it felt pressure, and 'wore out' after it had done this a few times -- a refractory period probably occurred." (Hastings, Arthur; personal communication, March 21, 1996) Comment. This is probably a pressureinduced biological phenomenon, but we have no idea what kind of organism produces the lights. Footsteps do produce a rapidly expanding pressure wave on damp sand, which whitens the sand as it moves outward. But we ...

Science Frontiers ONLINE No. 114: Nov-Dec 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Redefining Science The rules of today's science are rigorously objective, with no place for subjective or consciousness-related factors. 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. R.J . Jahn heads the Princeton Engineering Anomalies Research (PEAR) Laboratory, which over the years has conducted some 50 million experimental trials, mostly in the search for psychokinetic effects on the behavior of a wide variety of mechanical, electrical, and other types of ...

Strong evidence that plant life exists on Mars was advanced today by Earl C. Slipher, American astronomer, after observation of the planet, which is closer to the earth this month than at any time since 1924. .. .. . "His theory is founded on an apparent change in the planet's surface, regarded as his most important discovery. "The huge dark spot (Solis Lacus) or the Great Eye of Mars, seems to have assumed a shape not observed for fifty years, if ever before. Mr. Slipher indicated that this was strong evidence that plant life existed on the planet, and suggested that the change was due to fresh vegetation over an area roughly the size of the United States."

There are difference, too, but not as many as expected by psychologists who hold that we are shaped primarily by our environments. Only a few of the astounding (and strange) similarities can be recounted here. Two 39-year-old twins, meeting for the first time, were both wearing seven rings each, two bracelets on one wrist, a watch and one bracelet on the other wrist. Two men both had dogs named Toy, had married and divorced women named Linda, remarried women named Betty, and named their sons James Allan and James Alan. Two other males had similar medical histories: hemorrhoids, same pulse rates and blood pressures, same sleep patterns. Both had put on 10 pounds at the same times in their lives.

But armadillos possess a remarkable defense mechanism you should be aware of. Not all of them curl up into tight, nigh-impenetrable balls when threatened as the field guides promise us. Instead, some suddenly jump straight up -- as much as 8 feet high! Woe be to anyone hovering over armadillos favoring this type of defense. Broken noses, loosened teeth, and black eyes have been inflicted by these armored projectiles. Another unexpected habit of the armadillo is its crossing of small streams by walking along the bottom underwater. It can swim if necessary and gains buoyancy by filling its intestines with air.
