What astronomers do see is unsettling. The orbital eccentricities of the three inner satellites, using reasonable assumptions about tidal interactions, should decay to zero (perfect circles) in 107 -108 years. If the observational data are correct, one implication is that the Uranian satellite system should be evolving rapidly from a state of higher eccentricity. (Squyres. Steven W., et al; "The Enigma of the Uranian Satellites' Orbital Eccentricities," Icarus, 61:218, 1985.) Comment. Here we have one more sign of recent disturbance or solar-system youth. Time spans of 107 -108 years are very small compared to the estimated solar-system age of 5 x 109 years. From Science Frontiers #40, JUL-AUG 1985 . 1985-2000 William R. Corliss ...

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.

We'll have to wait another 70-or-so years for that. However, Halley did make a surprise reappearance on February 12, 1991. Astronomers were startled by a sudden flare-up. It was not a trivial brightening; the width of the flare was a remarkable 300,000 kilometers. Comets often flare up as they swing close to the sun and absorb its heat and radiation. But Halley is now billions of kilometers away in the frigid reaches of the outer solar system. No one knows what happened. (Pease, Roland; "Halley at Large," Nature, 349:732, 1991.) Comment. Other comets have mysteriously flared up far from the sun. See ACO2 in our catalog The Sun and Solar System Debris. Apparently comets harbor considerable pent-up energy. If proximity to the sun is not required to stimulate gas releases or chemical reactions, comets may have their own energy agenda. Comets seem to be little more than chunks of dirty ice. Where could the flare energy come from? If only cold fusion were a viable "acceptable" energy source! To order The Sun and Solar System Debris, see: here .

The woman had an immune-system disorder that had damaged a small portion of her brain's temporal lobe. Her other mental faculties were intact. "The woman could name plants, foods, and inanimate objects and describe them without hesitation. The scientists were impressed that when shown a trellis, not exactly your everyday object, she could correctly name it and describe its cross-hatched geometry. "But when shown a squirrel or a dog, she froze. She couldn't find the right name for either, nor could she describe their size or shape or furry coats. "Her deficit, involving only a tiny portion of her language skills, was amazingly narrow." (Bor, Jonathan; "The Woman Who Couldn't Describe Animals," Baltimore Sun, p. A1, September 7, 1992.) The implications of this strange case were described in Science News: "The peculiar inability of a 70-yearold woman to name animals has led scientists to propose that the brain harbors separate knowledge systems, one visual, the other verbal or language-based, for different categories of living and inanimate things, such as animals and household objects."

When Steele's research was announced, many scientists and science writers rushed to the defense of Darwinism. They pointed out with unseeming vigor that a revival of dread Lamarckism or the Inheritance of Acquired Characters was not indicated. It is true that Steele has proposed a Darwinian interpretation of his findings, but his theory adds a startling new dimension to the development of life. In essence, Steele asserts that an organism's immunological system is really the evolutionary scenario in miniature and compressed in time. The body's immuno-logical system is trying to cope with up to 10 million defensive cells. The only defensive cells that survive and multiply are those that happen to encounter an invader that they can lock onto and destroy. The "fittest" defensive cells are those that have just the right characteristics to knock off invaders, and only they survive permanently in the body's defensive arsenal, giving it acquired immunity. The Lamarckian part of this story occurs when the RNA of the selected defensive cells gets passed on to the organism's progeny.

It was quite fortuitous that the following two pieces, found on the same day, fit together so nicely. (Nature is fortuitous!) A group of scientists studying termites have isolated over 100 species of protozoa and bacteria living cooperatively inside the termites gut. Some of the bacteria even live inside the protozoa and other bacteria forming ecosystems of several symbiotic levels within each termite. Each termite itself is part of a complex social "superorganism," the termite colony. That termites had bugs in-side them has long been known; but the new-found complexity and interdependency of life systems within life systems is remarkable. The researchers believe that the life forms inside the termite work together to create the uniform internal environment needed by all inhabitants, just as the termites themselves cooperate to maintain a favorable environment inside their hill. (Anonymous; "And Littler Bugs Inside 'Em," Scientific American, 246:78, February 1982.) The termites, though, are only part of a much larger ecosystem, the earth itself. J.E .

"It is concluded that on five occasions during the interval 20,000-14,000 years BP, cosmic dust mass concentrations in the solar system rose by one and two orders of magnitude above present day levels. Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate. Thus it is quite possible that these dust congestion episodes were responsible for the abrupt climatic variations which occurred toward the end of the last Ice Age." Whence these interplanetary dust clouds? The author of this article ruled out terrestrial volcanism (an insufficient source of iridium) and encounters with asteroids and cometary tails (too infrequent to account for the long periods of high dust levels). Rather, the dust source may have been the same event that created the recently discovered dust ring between Mars and Jupiter, which is believed to be only a few tens of thousands of years old.

But all laterally symmetric organisms are prone to cancer. According to James Graham, the acquisition of cancer-initiating onco-genes by organisms (also an unexplained event) has forced these afflicted organ-isms to develop all sorts of defenses against external forces which might, with the help of the oncogenes, trigger cancer. Typical biological defenses include systems to insure accurate replication of cells, to destroy transformed cells, and to protect or immunize the organism against invading systems. Efficient im-mune systems in turn permitted life to invade mutagenic environments (such as sunlight) and to shed restrictive body coverings. In other words, cancer may have been a blessing in disguise -- the price of higher life| (Anonymous; "Cancer: The Price for Higher Life?" New Scientist, 99:766, 1983.) Comment.

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.

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.

Recently, H.B . Hammel, using the University of Hawaii's 2.2 -meter telescope, discovered that Neptune's northern hemisphere is now brighter than its southern -- something never observed before. During the past eight years, the southern hemisphere has been consistently brighter, although the hemispheres were of roughly equal brightness during the late 1970s.

An explanation is suggested by the fact that the dark side points in the satellite's direction of motion. A recent study of 12 Voyager images of Iapetus also imply an exogenous (externally imposed) origin of the dark surface, because they show a gradual rather than sharp transition between the dark and light regions.

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.

So, how did the marvelously crafted wings of birds, insects, and mammals evolve in infinitesimal steps? Biologists, including Darwin himself, have long puzzled over this. Stephen Jay Gould in a recent article explores a currently favored way of circumventing the negligible additional survival value of half a wing, or even 90% of a wing. This solution (? ) maintains that protowings were not "intended" for flight at all but were developed initially as aerodynamic stabilizers, thermoregulatory systems, sexual attractors or other functions requiring large areas. Gould describes the experiments of Kingsolver and Koehl in which protowings were modelled and tested for their thermoregulatory and flight values. Surprisingly, there was a sharp transition, as the size of the protowing increased, from good thermoregulation but poor flight capability to the reverse -- good flight capability and poor thermoregulation. In other words, a structure developed for one purpose, if enlarged, might be useful for something else! (Gould, Stephen Jay; "Not Necessarily a Wing," Natural History, 94:14, October 1985.

The earth's laser operates between frequencies of 50 and 600 kilohertz. Its emissions are known as the "auroral kilometric radiation" or AKR. While some of these terrestrial emissions are spontaneous, others are stimulated by Type-III solar radio bursts.

Falk discovered that an automobile's engine was limited in power by its radiator's capacity to cool it, he applied this thinking to the human brain. The human brain, like the automobile engine, must be kept cool if it is to function well. It follows that if the brain of an animal is not functioning well, the body that brain controls will not perform well either. Overheated brains, then, are sure roads to extinction in the highly competitive natural world. A couple million years ago, two groups of human precursors were competing for dominance in Africa. The group that won and subsequently evolved into Homo sapiens had, according to Falk, a better brain-cooling system. The evolutionary development that probably led to this advantage was a more extensive network of emissary veins, which permitted better dissipation of heat. This, in turn, allowed the evolution of larger brains and dominance by Homo sapiens. Other anthropologists, how ever doubt that such a minor change in the circulatory system could account for the emergence of modern man. (Shipman, Pat; "Hotheads," Discover, 12:18, April 1991.) Comment. What an intriguing concept! Perhaps human male baldness also confers more cooling efficiency and is setting the stage for a new expansion of the human brain -- at least the male brain, sorry girls!

It is only an unimposing geometric progression, which, if one inserts the earth's average distance from the sun, yields the distances of the other planets with enough accuracy to perturb astronomers. You see, all scientists abhor numerology. They must insist that the Titius-Bode Law has physical underpinnings. S. Weldenschilling and D. Davis now propose that the planets owe their present positions to a combination of two effects: The frictional drag of the gas in the solar nebula, which favors the presence of small planets in the inner solar system. Gravitational perturbations that create favored places for the coalesceing of planets. C. Patterson has expanded on this suggestion and finds that a model based on these effects works quite well for Jupiter and beyond, where planets are "bound together" in an interlocking system of orbital-period resonances. (See diagram.) Several important anomalies persist, however. That vacant niche between Uranus and Neptune is presently unexplained.

Yet, there is no agreement as to its mode of origin. One might say that planetary scientists have just about thrown in the towel on the three major theories of lunar origin. Two recent articles attest to this discouraging situation. A Sky and Telescope article provides an excellent review of all three theories, indicating the reasons why each fails to convince a majority of scientists. The theories and the primary reasons for their rejection are: (1 ) Fission from earth . Lack of sufficient angular momentum in the earthmoon system and the fact that the moon does not orbit in the plane of the earth's equator. (2 ) Gravitational capture . The capture of such a large object in a nearly circular orbit is considered too improbable. (3 ) Earth-moon accretion as a double planet . The compositions of the earth and moon are too different. This article concludes that the resolution of the problem of lunar origin must await our return to the moon for more scientific exploration. (Rubin, Alan E.; "Whence Came the Moon?"

Normal people experience this in dancing, fencing, etc. Extreme examples include sleepwalkers who can even drive cars and carry out other complex actions without remembering what they have done! Of course, sleepwalking is not a normal condition; nevertheless, rigorous experiments demonstrate that normal people will respond to scary pictures of snakes and spiders even though they are not consciously aware of them. The zombie agent is acting autonomously. Zombie agents are characterized as on-line systems that act at speeds that far outpace conscious reactions. Since the zombie agents incorporated in our unconsciousness work so well, why did consciousness ever evolve? Conscious actions take milliseconds longer to calculate and activate. Consciousness would, therefore, seem to be a bad evolutionary gambit. But, C. Koch and F. Crick may have an answer. They speculate that: It may be because consciousness allows the system to plan future actions, opening up a potentially infinite behavioural repertoire and making explicit memory possible.

Now, we have a long list of craters or astroblemes (star wounds), some of which measure hundreds of miles across. In fact, there are enough large dated crters so that some scientists have taken up a time-honored human pastime: Looking for cycles or periodicities in the data. (Humans can find cyclicities in almost any collection of data!) To be more specific, some have claimed that large meteor craters come in clusters dated 28-31 million years apart. These catastrophic events have been correlated with biological extinctions, magnetic field reversals, and basalt flooding. The astronomical causes of this supposed periodicity range from the solar-system's crossing of the galactic plane, to the perturbations of an unseen solar companion, to regular perturbations of the Oort cloud of comets that is thought to hover at the fringe of the solar system. In short, a large, interlocking edifice of geological and astronomical speculation has been erected upon a foundation of terrestrial crater ages. But how well do we really know the ages of these craters? How complete is the cratering record? The answer to the first question is: "Not well at all." Further, we can be certain that many craters still lie undiscovered beneath sediments. In addition, most meteors/comets splashed into the oceans, leaving no record at all.

This fish (different from the knife fish above) emits electric pulses at frequencies betwen 250 and 600 per second for electrolocation and communication. M. Kawasaki, at the University of Virginia, has investigated what happens when two of these fish operating on similar frequencies meet. Ordinarily, the fish would jam each other's sensory apparatus and "blind" each other. To circumvent this Eigenmannia has evolved a "jamming avoidance response," in which they both shift their pulse frequencies away from each other. To accomplish this, the fish must be able to detect time disparities between the two sets of signals less than 1 microsecond long. Their individual electroreceptors are not capable of handling such small time differences. Kawasaki has concluded that the jamming avoidance response can come only from highly sophisticated signal processing in the fish's central nervous system.

Rather, we might depart slowly, quietly, and mournfully. Of course, Eliot was not thinking of asteroids -- no one foresaw impact havoc in his day. But, his use of the word "whimper" can be attached to another, much slower astronomical agent of planetary death: cosmic dust and gas. Here's the current situation: "For the most part of the past five million years, the Solar System has been moving through a rather empty region of interstellar space between the spiral arms of the Milky Way. But a few thousand years ago, it entered a diffuse shell of material expanding outward from an active star-forming region called the Scorpius-Centaurus Association.

Science Frontiers ONLINE No. 99: May-Jun 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Ballistic Panspermia Scientists are already convinced that cratering events on the moon and Mars have propelled rocky debris in the direction of the earth, and that some of these fragments have landed here in the guise of meteorites. A logical question is: Can life forms and/or chemical precursors of life be transported thus across the far reaches of the solar system? Can one planet infect another ballistically? An analysis by M.K . Wallis and N.C . Wickramasinghe is rather warm towards this idea: "The mass of escaping ejecta from the presumed 10-km comet that caused the 180-km Chicxulub crater, with a radius of roughly 10 km and 1 m deep, amounted to ~300 Mm3 , of which one third may have been rock and 10% higher-speed ejecta that could have transited directly to Mars. It may have taken 10 Ma to impact Mars but...the probability is not exceedingly low but 0.1 -1 %. "The survival and replication of microorganisms once they are released at destination would depend on the local conditions that prevail. Although viability on the present-day Martian surface is problematical, Earth-to-Mars transfers of life were feasible during an earlier 'wet' phase of the planet, prior to 3.5 Ga ago. The Martian atmosphere was also denser at that epoch, with several bars of CO2 , thus serving to decelerate meteorites, as ...

Science Frontiers ONLINE No. 31: Jan-Feb 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects What causes the sunspot cycle?Even since the sunspot cycle was discovered, a few people have been trying to prove that it is caused by the influence of the planets, particularly Jupiter with its 11.86-year period. A century of various correlations has convinced almost no one. John P. Bagby has now introduced a new piece to the puzzle of solar-system cyclic behavior. 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. (Bagby, John P.; "New Support for the Planetary Theory of Sunspots," privately circulated paper, 1983.) Comment. Even "farther out" is the thought that gravitational waves or some unrecognized influence from the galaxy or beyond causes the whole solar system to "ring." In ...

Science Frontiers ONLINE No. 77: Sep-Oct 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mercury: the impossible planet Mercury, largely hidden in the sun's glare, also conceals beneath its baked, cratered surface: (1 ) far more iron than solar-system theory allows; and (perhaps) (2 ) a dynamo that should not exist. Let us take the excess-iron problem first. Mercury's density is 5.44 (compared to earth's 5.52), so that it very likely contains much iron. Our moon, which resembles Mercury in size and external appearance, only has a density of 3.34, implying an altogether different origin. In the currently accepted theory of solar-system formation, all of the planets and their satellites condensed from a primordial disk of dust sur rounding the just-formed sun. The planets closer to the solar inferno lost more of their easily vaporized constituents due to the sun's heat. The cooler, outer planets were able to retain large amounts of ices. In this scenario, we would expect Mercury to be rich in iron and rocks. This seems to be the case, but it has too iron to fit the theory. Astronomers have tried to save the theory by supposing that a large asteroid sideswiped Mercury tearing off part of its outer layer of lighter rocks, leaving the heavier iron core untouched. The theory doesn't say what happened to the debris from this colossal collision. As for Mercury ...

Science Frontiers ONLINE No. 108: Nov-Dec 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Those selfish genes may also be intelligent!R. Dawkins has proposed that we humans and other organisms are merely lumbering life-support systems for our genes. In this view, genomes are the masters, controlling our evolution and behavior to ensure their own survival and multiplication. In short, our genes are "selfish." J. Shapiro, at the University of Chicago, has gone a step further and ascribed still another human attribute to genomes. "Genomes function as true intelligent systems, which can be readjusted when conditions require. We still lack testable theories to explain how this can be done. ( Genetica , 84:4 , 1991)" Perhaps we see evidence of this "intelligence" of genes when bacteria and other microorganisms rapidly accommodate to environmental challenges, as in the application of new antibiotics. In this context, read below about the fast-evolving cichlid fishes of Lake Victoria. These fish must have macho genes! From Science Frontiers #108, NOV-DEC 1996 . 1996-2000 William R. Corliss ...

Science Frontiers ONLINE No. 39: May-Jun 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Saturn's rings may be young When the Voyager spacecraft swept past Saturn, they radioed back photos of a complex, very dynamic system of rings -- thousands of rings. Studies of these rings have led some astronomers to wonder if they are really as old as Saturn itself. Two lines of thinking suggest a recent origin: (1 ) The rings are composed of both light material (very likely water ice) and dark material (probably rocks and dust). The rocky fragments, according to the prevailing nebular theory, should have condensed early in solar-system history, and then been swept gravitationally into the planet as they were slowed by friction with the uncondensed nebular material. Yet, dark material is still in the rings. (2 ) The incessant bombardment of the rings by meteorites should have pulverized the rings, sending fragments and vaporized material in all directions. In just 10 million years the rings should have been largely erased. They are still there. (Cuzzi, Jeffrey N.; "Ringed Planets: Still Mysterious -- II," Sky and Telescope, 69:19, 1985.) Comment. Assuming the rings are young, where did they come from? What happened to Saturn in "recent" times? Reference. Several lines of evidence point to the youth of Saturn's rings.

Science Frontiers ONLINE No. 25: Jan-Feb 1983 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Promiscuous Dna The cells of plants (photosynthetic eukaryotes) are genetically the most complex that biologists have discovered. Each cell has three genetic systems: its own, that of the chloroplasts; and that of the mitochondria. It is supposed that the chloroplasts and mitochondria were once free-living cells that linked up with the embryonic plant cell to form a symbiotic partnership, with the host "plant" cell being the dominant member. Up until now, the three genetic systems were thought to be discrete, each going down its own pathway. But chloroplasts genes have now been found inside plant mitochondria, overturning conventional wisdom. To sum it all up, DNA seems promiscuous -- no respecter of privacy and breaking down all isolating genetic barriers. This discovery at once raises a dozen questions. For example, are mitochondria genes in chloroplast cells? How far does this promiscuity go? Can the same thing happen in higher organisms; say, with humans and symbiotic microorganisms or even not-so-symbiotic disease organisms? Is there no stopping this DNA? (Ellis, John; "Promiscuous DNA -- Chloroplast Genes inside Plant Mitochondria," Nature, 299:678, 1982.) From Science Frontiers #25, JAN-FEB 1983 . 1983-2000 William R. Corliss ...
