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.

Not only do they jump about within a species, but also between species, especially the simple prokaryotic organisms, such as bacteria. It is now well accepted that genes flow between different species of bacteria in physical contact, thus stirring the evolutionary pot. Until recently, scientists believed that the higher organisms, the eukaryotic species, including you and me, did not indulge in such "horizontal" traffic between species. But a few cases have now been found, one involving humans and a microorganism associated with tumors. And the search is just beginning, as biologists look for something they never thought of looking for before. (Lewin, Roger; "Can Genes Jump between Eukaryotic Species?" Science, 217:42, 1982.)

Since this cataclysm is predicted to occur on Jupiter's far side, the pyrotechnics will be largely hidden from our telescopes. Yet, if any of Jupiter's four large Galilean satellites are swinging behind Jupiter during the comet's impact, but still visible to us by virtue of their distances from Jupiter, we might see one or more of these moons suddenly brighten due to light reflected from the incineration below. This very well might happen, and something similar has happened before. On July 26, 1983, just 6 minutes after it emerged from behind Jupiter, the Galilean satellite, Io, suddenly brightened by 50% -- a "flash" that lasted 118 seconds. Now, Io is notoriously fickle brightness-wise. Its post-eclipse brightening has long puzzled astronomers, but this short, intense flash was even more anomalous than usual. H.B . Hammel and R.M . Nelson suggest that this 1983 flash might have been the reflection of some catastrophic event occurring on the hidden half of Jupiter -- possibly the impact of some large object -- or, even more intriguing, Jovian lightning.

We all know about the placebo effect. A sick patient improves because he believes he is getting a helpful medicine, even though it is an inert substance. The reverse works, too, at least in experiments with mice. It seems that mice can be conditioned into believing that an ordinarily delectable substance (saccharin and water) gives them stomach pain, by simultaneously injecting them with a pain-producing chemical. Unexpectedly, this chemical also suppressed the immune system of the mice. The mice, of course, knew nothing about the effect on their immune system. Nevertheless, whenever they received saccharin after being conditioned, their immune system was suppressed even though the pain-producing chemical was not administered. While one can imagine the mice consciously associating saccharin and stomach pain, and their brains somehow sending signals that simulated pain, it seems inconceivable that the mice knew anything about their immune system. We have always assumed that the placebo effect (and its reverse) worked because of the subjects' logical association of cause and effect, but evidently there is something else going on here!

Why Barbie Is Beautiful. A study of a long series of hominid fossils reveals a progressive loss of some physical attributes and the acquisition of other characteristics. One wonders why evolution has been remodeling the human form in what often seem to be nonadaptive ways. A curious, superficially frivolous test may offer some insights, some of which may be profound. Drawings and photographs showing humans with various physical traits were prepared and shown to 495 subjects, who were asked to select the most attractive characteristics. In disfavor were: short shins, short legs, bowed legs, large and pointed canines, gums showing above the teeth, short thumbs, long palms, curved fingers, jutting jaws, short necks. These are all primitive features still seen in apes and monkeys. Favored were: tallness, long legs, slim waists, long necks, curved red lips, large eyes, square shoulders, straight teeth, straight fingers, smooth and hairless skin, nonsloping foreheads, flat abdomens. These are all features "derived" during evolutionary history. A look at a photograph of a Barbie doll, which accompanied the article, proves that Barbie epitomizes these favored characteristics.

... named after him. Of course, we anomalists become wary when scientists "generally agree" on a hypothetical entity that no one can see. The Oort Cloud of comets, like the unseeable black holes, are given substance only by the effects they have on other solar-system denizens and seeable cosmic objects. But there may be another cloud of comets that we can view directly. It is called the Kuiper Cloud (after G. Kui per). It is concentrated in the plane of the ecliptic just beyond the orbit of Neptune. Like the Oort Cloud, the Kuiper Cloud has not been seen yet, but we just might be able to with today's equipment! Its existence is hypothesized from the parameters of a different group of comets -- the so-called "short-period" comets, as exemplified by 76-year Halley's Comet. About 120 short-period comets have been discerned so far; and our computers now tell us that they cannot have originated in the Oort Cloud. Something closer and concentrated on the ecliptic is required. Thus the Kuiper Cloud or Belt was born. It is thought to be composed of debris left over after the formation of the solar system. (Kerr, Richard A.; "Comet Source: Close to Neptune," Science, 239:1372, 1988.) Just before the referenced Science article appeared, a piece on comet origins was printed in the New Scientist.

Caddy" is short for Cadborosaurus , the speculative sea animal seen rather frequently off the British Columbia coast and as far south as Oregon. Professor P. LeBlond, University of British Columbia, recently presented a paper on Caddy at a joint meeting of the Canadian and American Societies of Zoology. Of all the supposed sea serpents, Caddy seems closest to respectability. Not only are there many sightings on record, but the remains of a 3-meterlong carcass of an apparent juvenile specimen of Caddy was discovered in the stomach of a sperm whale. Adult Caddys are about 7 meters long. "The descriptions [of Caddy] are generally similar. They suggest a long-necked beast with short pointed front flippers, a horse-like head, distinct eyes, a visible mouth and either ears or giraffe-like horns. Often Caddy is described as having hair like a seal, and sometimes a mane along its neck." Most interesting is Caddy's body hair, which implies a mammal rather than a reptile. But if it is a mammal, how does it get air, since it surfaces so rarely? Some have suggested that the giraffe-like horns are snorkels! But E. Bousfield, a colleague of LeBlond, thinks that the tubercules reported along the animal's back might be gill-like tissues that would allow a mammal to extract oxygen from seawater! With so ...

Two hundred million years seems a bit on the short side for the spontaneous generation of life, although no one really knows just how long this process should take (forever?). The apparent rapidity of the onset of terrestrial life has led to a reexamination of the old panspermia hypothesis, in which spores, bacteria, or even nonliving "templates" of life descended on the lifeless but fertile earth from interstellar space. P. Weber and J.M . Greenberg have now tested spores (actually Bacillus subtilis) under temperature and ultraviolet radiation levels expected in interstellar space. They found that 90% of the spores under test would be killed in times on the order of hundreds of years -- far too short for panspermia to work at interstellar distances. However, if the spores are transported in dark, molecular clouds, which are not uncommon between the stars, survival times of tens or hundreds of million years are indicated by the experiments. Under such conditions, the interstellar transportation of life is possible. But perhaps the injection and capture phases of panspermia might be lethal to spores. Weber and Greenberg think not -- under certain conditions. The collision of a large comet or meteorite could inject spores from a life-endowed planet ...

The abstracts of these papers are short and to-the-point, so we quote them: "We have performed an experimental test of Newton's inverse-square law of gravitation. The test compared accurately measured gravity values along the 600 m WTVD tower near Raleigh, North Carolina, with upward, continued gravity estimates calculated from ground measurements. We found a significant departure from the inverse-square law, asymptotically approaching -547 36 microGal at the top of the tower. If this departure is derived from a scalar Yukawa potential, the coupling parameter is alpha = 0.023, the range is lambda = 280 m, and the Newtonian Gravitational Constant is G = (6 .52 0.01) x 1011 m3 kg-1 s-2 . We do not yet have adequate resolution to discriminate this scalar model from a scalarvector model."

Van Flandern, editor of the Meta Re search Bulletin, has compiled a list of Big-Bang problems -- and it is not a short list. Can the Big-Bang paradigm be that shaky? Like Evolution and Relativity, the Big Bang is usually paraded as a proven, undeniable fact. It isn't . Static-universe models fit the data better than expanding-universe models. The microwave "background" makes more sense as the limiting temperature of space heated by starlight than as the remnant of a fireball. Element-abundance predictions using the Big Bang require too many adjustable parameters to make them work. The universe has too much largescale structure (interspersed "walls" and voids) to form in a time as short as 10-20 billion years. The average luminosity of quasars must decrease in just the right way so that their mean apparent brightness is the same at all redshifts, which is exceedingly unlikely. The ages of globular clusters appear older than the universe. The local streaming motions of galaxies are too high for a finite universe that is supposed to be everywhere uniform. Invisible dark matter of an unknown but non-baryonic nature must be the dominant ingredient of the entire universe. The most distant galaxies in the Hubble Deep Field show insufficient evidence of evolution, with some of them apparently having higher redshifts (z = 6-7 ) than ...

This paper reports a systematic study of a man (T .E .) with astonishing mnemonic skills. After a brief description of his most favoured mnemonic technique, the 'figure alphabet,' his performance and the mnemonic techniques used on five classical memory tasks are described. These are: one task involving both short- and long-term memory (the Atkinson-Shiffrin 'keeping track' task), two tasks involving just longterm memory (recall of number matrices and the effects of imagery and deep structure complexity upon recall), and two tasks involving just short-term retention of individual verbal items and digit span. Whenever possible, T.E .' s performance was compared with that of normal subjects, and also with other mnemonists who have been studied in the past. There was no evidence to suggest that T.E . has any unusual basic memory abilities; rather he employs mnemonic techniques to aid memory, and the evidence suggests that previous mnemonists who have been studied by psychologists have used very similar techniques." The "figure alphabet" employed by T.E . was used in Europe as early as the mid-1700s. The Hindus had a Sanskrit version even earlier.

Accelerator experiments at Berkeley have again focussed attention on those few fragments from nuclear reactions that have unexpectedly short trajectories. About 6% of these fragments travel only about one tenth as far as prevailing physical laws say they should. These anomalously short mean free paths are not new, having first cropped up in 1954, but they have gone unexplained for 26 years. Current speculation is that the anomalous fragments somehow change their identities, making them more susceptible to collision (i .e ., their collision cross sections spontaneously increase by ten times).

Initially, it was thought to be a condensation trail, but this was shortly dismissed as it was considered too low (estimated to be less than 10,000 ft altitude, probably around 7,0008,000 ft).

Not only is this complexity persistent under the attack of the Second Law of Thermodynamics, but it seems to actually increase with time. Do formative or guiding principles exist that science does not take into account? The two articles have very different answers. The creative cosmos. "Most people accept without question that the physical world is coherent and harmonious. Yet according to the traditional scientific picture, the Universe is just a random collection of particles with blind forces acting upon them. There is, then a deep mystery as to how a seemingly directionless assembly of passive entities conspire to produce the elaborate structure and complex organisation found in nature." The author of this introductory paragraph, P. Davies, asks, as we all do, "What is the origin of this creative power?" In groping for an answer, he presents first a common example of "blind" organization: the hexagonal convection cells in a pan of heated water. Using for a stepping stone the cooperative action of atoms in a laser, he leaps to the development of an embryo from a single strand of DNA! All such systems are "open"; that is, energy can flow in and out. They are also nonlinear, which means that chaotic, unpredictable action ...

The species P. chapmani builds low mounds of pebbles over its burrow systems, and P. hermannsburgensis may use these mounds after they are constructed. The pebbles are of a uniform size and cover a large area, often a meter in diameter. The pebbles are probably collected both by excavation and from the surface. Some local mammalogists believe these are used as dew traps. Since the air around the pebbles warms more rapidly as the sun rises than do the pebbles themselves, dew forms on the pebbles by condensation. As the areas in which these mounds are found are quite dry, except after a heavy rain, these dew traps solve the problem of water shortage. Local farmers use the many pebble mounds for mixing concrete. It is believed that the ancient people of the Mediterranean region used a dew trap method comparable to that of P. chapmani ."

Heavy rain began to pelt the ship, and a furious wind sprang up out of nowhere. Squalls were nothing new to the Marques , one of 39 tall ships participating in a transatlantic race. But as a precaution, Stuart Finlay, the seasoned 42-year-old American captain of the ship, shortened the sails. The Marques was carrying a crew of 28 - half of whom were under 25. At the helm, Philip Sefton, 22, fought the angry waves that now confronted them. "Suddenly a heavy gust of wind pushed the Marques down on its starboard side. At the same instant 'a freakish wave of incredible force and size,' as Sefton later described it, slammed the ship broadside, pushing its masts farther beneath the surging water. A second wave pounded the ship as it went down. The Marques filled with water and sank in less than one minute. Most of the crew were trapped as they slept below deck. Only Sefton and eight shipmates survive." Accounts such as that above are part of sea lore. Waves 50-100 feet high have been frequently reported over the years.

A famous example of the latter seichedriving force occurred on March 27, 1964, when the Great Alaskan Earthquake sent seismic waves rippling around the globe. Fourteen minutes after this quake, the tremors reached the U.S . Gulf coast and triggered numerous seiches in bays, harbors, canals, bayous, etc. Some crest-to-trough waterlevel oscillations reached 2 meters in amplitude. Startling though these seiches were to Gulf fishermen, most seiches are wellexplained. Bodies of water that are mostly enclosed have natural frequencies of oscillation or "sloshing," just as do coffee cups and bathtubs.

They employed radio waves to drive beryllium ions from one energy level to another. While the beryllium ions were jumping from one level to another, the researchers sent in short pulses of light to determine the ion's state. The more frequently they inter rogated the ions, the less apt they were to jump to new energy states, despite the stimulating radio waves.

We have room for only a short section of their abstract: " .. .in the end we were left with a residuum of positive findings: (a ) There is a weak but persistent statistical relationship between lowish absolute levels of geomagnetic activity and the occurrence of spontaneous cases of apparent telepathy/clairvoyance. (b ) There is a small tendency for the days on onset of cases of poltergeists and hauntings to be days of higher-than-usual geomagnetic activity. What underlies these observed relationships remains to be determined." Gauld noted in his letter of transmittal that the conclusions of Wilkinson and himself were at variance with the item in SF#95.

The short-range "radars" of these fish are marvelously sophisticated, considering the low limb fish occupy on the Tree of Life. In fact, the following introductory paragraph from an article in Nature sounds almost as if it came from a textbook on electronic signal processing. "Behavioural experiments have demonstrated that certain species of fish can perform remarkable analyses of the temporal structure of electrical signals. These animals produce an electrical signal within a species-specific frequency range via an electric organ, and they detect these signals by electroreceptors located throughout the body surface. In the context of one electrosensory behaviour, the jamming avoidance response (JAR), the fish Eigenmannia determines whether a neighbour's electric organ discharge (EOD), which is jamming its own signal, is higher or lower in frequency than its own. The fish then decreases or increases its frequency, respectively. To determine the sign of the frequency difference, the fish must detect the modulations in the amplitude and in the differential timing, or temporal disparity, of signals received by different regions of its body surface. The fish is able to shift its discharge frequency in the appropriate direction in at least 90% of all trials for temporal disparities as small as 400 ns." (Rose, Gary, and Heiligenberg, ...

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.

This is Periodic Spring, whose intermittent flow is a rare geologic phenomenon. The water is cold and clear, an indication that this is not a geyser like Old Faithful; such geysers, of volcanic origin, send forth hot water. Through the years various observers have timed the flows at anywhere from four to twentyfive minutes, with similarly varying dry spells. The intermittent flow is especially regular in late summer and autumn. During stormy periods or when there is heavy snow melt-off, the flow fluctuates but does not stop entirely." At full flow, Periodic Spring discharges about 285 gallons/second into a stream 9 feet wide and 1 feet deep. Periodic Spring, therefore, is fairly impressive, but it is not anomalous.

Wickramasinghe and F. Hoyle. Comet Hyakutake, they said, was not emitting X-rays itself. Instead, solar X-rays were mirrored in earth's direction by a cloud of very tiny carbon-containing particles released by the comet. Electrons in these nanometer-sized particles acted as if they were free electrons, and these are excellent scatterers of X-rays. Anyone familiar with the writings of Hoyle and Wickramasinghe can guess what these nanometer-sized particles might be: viruses, of course! Said Wickramasinghe: "It all fits in the the idea that there are real viruses in comets and that comets are the agents by which life is brought to planets."

Despite much anecdotal evidence and the convictions of many parents, biologists have not generally recognized the reality of short, sharp growth spurts on the order of 1 centimeter in a single 24hour period. Rather, the consensus has been that child growth was divided into three stages (infancy, childhood, adolescence), each characterized by different, but steady rates of growth. This conclusion was based upon annual and quarterly length measurements. However, when children are measured more often (weekly or daily), the growth curve is seen to be step-like rather than smooth, as in the accompanying illustration. Indeed, the mean amplitude of the growth spurts was found to be about 1 centimeter; and the duration of the spurts, about one day. These spurts punctuated long intervals of no growth. In infants, for example, 90-95% of their development is growth-free! (Lampl, M., et al; "Saltation and Stasis: A Model of Human Growth," Science, 258:801, 1992.)

Science Frontiers ONLINE No. 49: Jan-Feb 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Monarch Migration An Illusion "The epic autumn migration of the eastern monarch butterfly to wintering grounds in Mexico, where millions cluster on trees in semi-dormancy to await spring, has become known as one of the standard 'wonders of nature' in the decade since the Mexican winter clusters were found." There are, however, some flies in this ointment: Monarchs tagged in the north have never been found in the Mexican clusters. Fall-fattened monarchs can store only enough energy for a flight of about 200 miles -- far too short, unless they refuel along the way (no one knows if they do or not); and The monarchs seen in Mexico are almost always in pristine condition and show no wing wear or tattering. A.M . Wenner, University of California at Santa Barbara, thinks that the "appearance" of mass migration reported frequently from many locales may just be due to a curious fall habit of the monarchs. It seems that widely scattered individuals begin to fly into the wind, and the wind concentrates and channels them to local roosts where they spend the winter. In other words, there is no long distance migration at all. (Rensberger, Boyce; Washington Post, September 15, 1986. Cr. J. Judge) From Science Frontiers #49, JAN-FEB 1987 . 1987-2000 William R.

... a phenomenon has "made it" when a book is devoted to it. With the English crop circles, we now have two books (bibliographical information below.) We will try to stock at least one of these books, but it will be a few months before can can get them on this side of the Atlantic. Meanwhile, a review of the two books in New Scientist provides some information beyond that already presented in several past issues of SF. First, the crop circles, spanning 5 to 20 meters, are incredibly precise and sharp. Flattened stems on the periphery of a circle almost touch erect, undamaged stems. The so-called satellite circles that sometimes array themselves around the main circles may be connected by a narrow ring, thus: Even more curious, a short radial spur extends outward from some circles, so that from the air the circle resembles a fat tadpole. In his book, G.T . Meaden, the Editor of the Journal of Meteorology, U.K ., presents his theory of how the circles are incised in field crops: "He describes the clues that have enabled him to point to the circles being formed by the impact of a body of fast-spinning air that has been partially ionized. He explains how a columnar atmospheric vortex, with a vertical or inclined axis, provides the channel for the formation of a plasma (ionized gas) vortex and for its conduction towards the ground. The ionisation of the air ought to be sufficient to make the vortex luminous at night and the fast spin may make the ...

It can be written as m 2+ n 2 , a sum of two squares of integers, in just 4 ways, namely when the pair (m , n) is (2 , 2), (2 , -2 ), -2 , 2), and (- 2 , -2 ). The integer 7, on the other hand, cannot be written as the sum of any squared integers. On the average, over a very large collection of integers from 1 to n, in how many ways can an integer be written as the sum of such squares?

... supernova 1987A, the first nearby super nova since 1604 AD. 1987A's nearness has given astronomers the opportunity to identify just which star exploded. (Other supernovas have been much too far away.) The prime suspect was the star Sanduleak -69 202. But then it was claimed that old -69 202 was still alive and well. This presented a quandry because no other star in the area was large enough to go supernova. But now it seems there was a mistake, and it was Sanduleak -69 202 all along that detonated. (Waldrop, M. Mitchell; "Supernova 1987A: Notes from All Over," Science, 236:522, 1987.) Comment. Naturally all of astronomy heaved a sigh of relief over this. Unfortunately, the relief was short-lived, and a second dose of antacid now seems required! Just a few days after the above, researchers reported in the New York Times some discomforting news: "According to Dr. Robert W. Noyes of Harvard-Smithsonian (Center for Astrophysics), the observations gathered by an extraordinarily sensitive camera show that the bright exploding star, or supernova, is actually two points of light, very close together, one about 10 times brighter than its companion. Since neither was present before the explosion, astronomers assume both arose from the same blast, but how this could happen is a mystery. .. .. . "The supernova and its apparent companion lie in the Greater Magellanic Cloud, a satellite galaxy of our Milky Way, at a distance of 150,000 ...

Science Frontiers ONLINE No. 52: Jul-Aug 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Nose news "Renewed discussion of a nasal breathing cycle, first discovered 5000 years ago, has recently been documented in the November 1986 issue of American Health by David Shannahoff-Khalsa of the Khalsa Foundation for Medical Science. Apparently the yogis of ancient India were the first to notice that breathing is dominated by either the right or left nostril for short cycle spans of one to three hours. (Cycles of this duration are known as ultradian rhythms, and are common to many biological functions.) By simply placing a mirror under your nostrils and watching for the larger amount of condensation, one can determine which nostril is in use. "What are the ramifications of this seemingly insignificant phenomenon? The yogis reportedly have said that improved sleeping, more satisfying sex, enhanced digestion, and appropriate thought patterns were controlled by the use of a certain nostril." It is further maintained that one can force a change in nostril breathing through meditation. In this way, it is possible to enhance sleeping, sex, digestion, and mental acuity! (LeBow, Howard A.; "Have You Heard about This One?" Cycles, 37:191, 1986.) Comment. All we know is what we read in the journals!
