The reasons are several: The observed universe is extremely homogeneous, even though theory says that distant parts of the universe could never have been causally connected; No satisfactory explanation exists for the density fluctuations that had to occur for galaxies to be formed; and The universe seems to be flat, not curved, and the Big Bang does not explain why. Paul Steinhardt and Andreas Al-brecht, at the University of Pennsylvania, have developed a radically different Big Bang -- a two-stage one, with hot and super-cooled states. The three objections listed above are neatly disposed of in the new version, but at the cost of a radically new view of the cosmos. The "new" universe is about 10100 times as big as the 12 billion light years assigned to the cozy universe we used to know -- and it is presumably correspondingly older. This means that the portion of the cosmos we see is only a negligible fraction of the whole -- a fraction that just happens to be homogeneous. Somewhere, way out beyond the farthest quasar, things could be -- well -- different! (Anonymous; "A Bigger, Better Big Bang," Astronomy, 11:62, February 1983.) Reference.

Without question, some people can reproduce incredible blocks of words and numbers as well as drawings, music, etc. The question is: Is such exceptional memory the consequence of an exceptional brain or just long training? Those who hold the first position believe an anomaly exists because: (1 ) The difference between normal memory and exceptional memory is so large; and (2 ) People with exceptional memory seem to employ different mental processes in transferring information into long-term memory, notably visual techniques like 'photographic' memory. The authors of this article present several cases where subjects with normal memory have been trained to where they perform nearly as well as memory experts. The key seems to be the use of mnemonic devices and other methods of imposing some sort of order or meaning on the information involved. To illustrate, a chess master can usually recall the positions of all the pieces on a chessboard after a quick glance. But if the chessmen are arranged randomly and meaninglessly, his memory is reduced to near-normal. The gist is that long prac-tice and the application of mnemonic devices can vastly improve anyone's memory and, in consequence, memory prodigies are not really so anomalous. (Ericsson, K.

... genome. We know about the components of genomes that could be made available for such restructuring. We know nothing, however, about how the cell senses danger and instigates responses to it that often are truly remarkable." Thus Barbara McClintock ends the paper she delivered in Stockholm when she received a Nobel Prize in 1983. Most of McClintock's paper reviews her pioneering work with the corn genome, but she adds some examples of other genomic responses to external stresses. One such stress is applied to an oak tree when a wasp lays its egg in a leaf. The stress causes the oak genome to reprogram itself and construct a wholly new and unplanned plant structure to house and feed the developing insect. Some of these structures (galls) are very elaborate and are precisely tailored to each different wasp species. From such examples, it is apparent that the genome of an organism somehow perceives stresses and reacts to them -- often in completely unanticipated ways. The stresses may be mechanical, thermal, chemical; in fact, almost anything. McClintock's conclusion is: ". .. that stress, and the genome's reaction to it may underlie many formations of new species." (McClintock, Barbara; "The Significance of Responses of the Genome to Challenge," Science, 226:792, 1984.) Comment. The implications here are broad and deep. Evolution can be driven by external stresses. The new species thus produced may differ substantially from the original organism, eliminating the need to look for "missing links" in the fossil record. ...

Pollard notes that quantum mechanics contains no hint of God per se and possesses no numinous quality, but its great complexity and multidimensionality provide evidence for "the reality of the transcendent order in which the natural universe is embedded." Example 2. The singularity at the beginning of the universe. Science is at a loss to explain creation and what happened before. (Pollard assumes that creation occurred like most scientists.) Example 3. The anthropic principle can be interpreted as a restatement of the religious contention that the universe was made-for-humankind. In Pollard's words: "If one imagines an ensemble of universes of different size and duration and equipped with different values of the fundamental constants G, h, c, e and others, this principle selects only that member of the ensemble for which life and its evolution to man is a possibility. But merely stating the problem in this way suggests a creator with a mysterious plan or purpose of his own. And certainly by any standard for judging a creative artist, to carry life from bacteria to man in three billion years is a startlingly immense creative achievement.

This is a very delicate situation. The difference between cancer and no cancer is simply too tiny. Given the high frequency of random changes (mutations), we should all have cancer. One implication is that humans (and other animals, too) have come up with some method of preventing or correcting these minor mutations -- otherwise we would have become extinct long ago.

... This Issue Sourcebook Project Sourcebook Subjects Bones Of Contention Introduction. This item needs an editorial because it shows how a very tiny and obscure brick in the Temple of Science, long thought to be structurally sound, might lead to widespread collapse. Are there other sleepers? A group of burrowing lizards (the amphisbaenians) possess a heavy bone in their heads that helps them ram their ways through the soil. In surface-living lizards this structure is merely a soft, flimsy cartilage. It was long assumed that the bone in the burrowing lizard developed from the cartilage of its surface-living kin. But a study of embryos now shows that the head bone of the burrowing lizard actually developed from a membrane instead of cartilage. The two similarly located structures are not homologous after all. They had different origins. Superficially this doesn't seem very anomalous and especially not very exciting. But vertebrate evolution in particular has been charted on the basis of homologous structures. If these structures have different biological origins -- even in just some cases -- the evolutionary family trees may be drawn wrong. (Anonymous; "Lizard Bone Shakes World of Taxonomy," New Scientist, 98:221, 1983.) Comment. No one yet knows how serious this problem really is. Basically it means that some animals that look alike (at least bonewise) need not be closely related.

Here are their conclusions: "We have shown that continuous sonar monitoring for seven weeks to a depth of 33 meters in an area where many previous sonar contacts had been reported showed no evidence of anything larger than a 1-meter fish. The circumstances under which previous expeditions had obtained sonar and photographic evidence in support of the existence of the Loch Ness monster could not withstand scrutiny. The evidence itself revealed discrepancies. This is especially true of the Academy's flipper photographs, the published versions of which differ from the original computer-enhanced photographs. Careless deployment of equipment and over-zealous interpretation of the data account for much of the so-called scientific evidence. While it is not possible to prove definitely that the monster does not exist, the evidence so far advanced strongly suggests that the Loch Ness monster is nothing more than a long-lived and extremely entertaining legend."

No one knows why these glaciers behave so differently from normal glaciers; they certainly look the same. But while ordinary glaciers creep along a few inches per day , surging glaciers will sometimes charge ahead at the rate of several yards per hour . The surges may be years apart; and they may occur periodically. The surges start high up on the glacier and propagate down to the foot, which plods along a few inches per day until the surge arrives. Then, it leaps forward, only to return to normality until the next periodic surge. The surges seem to occur when water spreads out under the ice, lubricating its flow. Beyond this we know little. Why do some glaciers surge while those right alongside behave normally? Are the surges really cyclic? The Variegated Glacier, in Alaska, for example, surged in 1906, probably in 1926, in 1947, in 1964-65, and in 1982 -- about 20 years between surges. The surges do not seem to be connected to earthquakes, climatic changes, volcanic heat, or anything obvious. (Beard, Jonathan; "Glaciers on the Run," Science 85, 6:84, February 1985.)

Vrba, of the Transvaal Museum, in Pretoria, stated: "If we eventually are able to establish a good time resolution with the continental record, I expect to be able to discern synchronous pulses of evolution that involve many groups of fauna and flora. Many different lineages in the biota will respond by synchronous waves of speciation and extinction to global temperature extremes and attendant environmental changes. This is my starting hypothesis." Vrba was speaking mainly about the last 25 million years, a mere flash in geological time. For this brief period, the Deep Sea Drilling Program has provided geologists with a detailed and continuous record of climate changes as they were recorded in deep-sea sediments. By contrast, the faunal history of the continents is rather fragmentary, making it rather difficult to match up pulsations of climate with pulsations of life. Even so, scientists have found rather strong correlations between climatary change and biological speciation and extinction at 15, 5, and 2.4 million years ago. (Lewin, Roger; "The Paleoclimatic Magic Numbers Game," Science, 226:154, 1984.) Comment. Note that this is just the period our ancestors seemed to be evolving rapidly.

Wind rather than water is now the main erosional force. The sand dunes and drifts, the wind-shadows behind rocks, and the sand-blasted surfaces all attest to the desertification of Mars. Ronald Greeley, of Arizona State University, and his colleagues have simulated Martian winds in a special wind tunnel at NASA's Ames Research Center. Using spacecraft-measured wind velocities and patterns, they tried to duplicate the Martian erosional environment. The results were a surprise. They implied that the Martian surface should be worn down by wind-driven sand and dust at rates up to 2 centimeters per century. But at that rate, the Martian craters, which are estimated to be hundreds of millions of years old, would have been worn level long ago. The researchers are now wondering what is wrong with their simulation. They venture that the Martian sand may not be "normal," or perhaps the eroding particles do not travel as fast as they figured.

When examined in detail, these lobes turn out to be quite different in size, shape, and intensity. In particular, very bright regions on one lobe often correspond to gaps or regions of low brightness on the other. So striking are these asymmetries that astronomers think that these huge, tremendously energetic systems are ejecting material first from one side then the other. Somehow, one side of the galaxy or quasar communicates with the other, which may be many light years away, and coordinates a flip-flop action. How and why radio galaxies and quasars should flip-flop is a major mystery. (Anonymous; "Flip-Flop Radio Jets?" Sky and Telescope, 68:506, 1984.) Comment.

The strata are erosional remnants up to 5 kilometers high, with individual layers 170-220 meters thick. They can be traced on spacecraft photographs for some 50 kilometers. The material making up the strata is clearly different from that of the valley walls. After the layers were deposited, they were deeply eroded by some event in Martian history that seems related to the formation of the great outflow channels associated with Valles Marineris. The author of this American Geophysical Union paper concludes: "The morphology and history of the sediments are consistent with deposition in standing bodies of water early in Martian history."

Furthermore, recent experiments suggest that in humans, in addition to seals and ducks, vascular constriction is not limited to the arterioles but extends to the larger arteries, too. This indicates some degree of specialized adaptation to a diving life. Most animals with a sodium deficiency display an active craving for salt which, when satisfied, disappears. In humans, salt intake has little or no relation to the body's needs. Some Inuit tribes avoid salt almost completely, while people in the Western world consume 1520 times the amount needed for health. In other works, a single African species (assuming humans have an African origin) possesses a wildly different scheme of salt management. Humans are also the only primates to regulate body temperature by sweat-cooling, a system profligate in the use of sodium. Proponents of the Aquatic Ape Hypothesis believe that sweat-cooling could not have developed anywhere except near the sea where diets contain considerable salt, in fact much more salt than the body requires. This article also deals with certain skeletal features of early man that seem to indicate an aquatic stage. For example, the Lucy skeleton has a shoulder joint that indicates that Lucy spent a lot of time with her hands above her head, as she would have if aquatic or treeswinging!

Early on, cladism ignited many fireworks in the biological community. Today, cladism has become quite respectable. The cladists, however, are now fighting among themselves. One camp draws their "cladograms" (see illustration) using evolutionary theory as a guide. The other side believes that the cladograms should be drawn up first, based only upon actual characters and ignoring the theory of evolution -- let the species fall where they may. When evolutonary theory is omitted in the deliberations, radically different cladograms result. Mammals then seem more closely related to birds than reptiles, for example, as expressed in the illustration. A key connecting character here is mutual warmbloodedness. The shifting of a few lines in a cladogram may seem trivial to the nonbiologist, but saying that man is more closely related to a chicken than a lizard is pretty controversial stuff to the conservative evolutionist.

... 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?" Sky and Telescope, 68:389, 1984.) An article in Science also discusses the classical theories of lunar origin and quickly disposes of them for the above reasons. However, a fourth theory makes an appearance, which we might call the Big Splash Theory. The idea is that a Mars-sized object (1 /10 the earth's mass) made a grazing collision with the earth when the solar system was more heavily populated with debris. This collision vaporized the projectile's rocky mantle as well as a similar quantity from the earth. This material was ...

... 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. Gubbins found that these externally caused pressure changes were too small to explain the polarity changes. However, the parameters involved are not well-known, and external triggers cannot yet be written off. Summarizing, very little progress has been made in explaining how the earth's field is generated and how polarity changes are linked to other geophysical parameters.

C. elegans is a roundworm, but a famous one. Its growth has been followed on a cell-bycell basis from egg to adult. The history of each cell is known from birth to death. The fact that C.elegans is nicely transparent helps the cell-watcher. Here are some of the interesting things to be seen as cells proliferate, live, and die. First, C. elegans is bilaterally symmetrical, but the pattern of cell generation on the right differs from that on the left. Nevertheless, the creature ends up symmetrical, making one wonder where the directions for symmetry come from. Some cells are transients, dying when their jobs are done. A few doomed cells are generated only because they produce sister cells that are needed in the final animal. Such a programmed loss of cells may be a method of modifying an organism during evolution.

"Merzenich's findings challenge a prevailing notion that most sensory pathways in the nervous system are 'fixed' or 'hardwired' by the maturation of anatomic connections, either just before or soon after birth. They also address the puzzling question of what forces may be at work when stroke victims partly recover. Do 'redundant copies' of skills exist outside the damaged regions, or is physical damage within the brain repaired over time? Or can old skills be newly established in different, undamaged brain regions." Apparently the brain should really be compared with a reprogrammable computer.

These experiments are not yet conclusive; and if the neutrino mass is not zero, it hardly weighs more than the grin of a Cheshire cat. But taken together, the laboratory results confirm that neutrinos are perplexing particles. Are they different entities or a single species wearing different costumes? The implications of the recent measurements are far-reaching: Physicists believe that there are a billion neutrinos around for each nucleon (proton, neutron, etc.) so that if neutrinos possess just a hint of mass, they will dominate the mass of the universe; and Measurements of solar neutrinos fall short by a factor of three of what theory says the sun should spew out.

Most examples of convergent evolution involve closely related species. In the present case, though, the species are in different phyla.

One would expect a strong advantage to be conferred on one or the other species, especially in the matter of predation. Using brook trout as predators, how ever, proved perplexing, for the trout would eat only the snails, avoiding the carbon-copy larvae.

By chemi-cally analyzing beetle and termite cuticles, they have found both wearing the same hydrocarbon labels. Furthermore, the beetles synthesize their own chemical masks. This is an astounding instance of parallel or convergent evolution between remotely related species. (Howard, R.W . et al, "Chemical Mimicry as an Integrating Mechanism....," Science, 210:431, 1980.) Comment. Synthesizing exactly the right hydrocarbons was certainly a great stroke of good fortune for the beetles! From Science Frontiers #14, Winter 1981 . 1981-2000 William R. Corliss ...

Science Frontiers ONLINE No. 15: Spring 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Distant galaxies look like those close-by Apropos the preceding item that the Expanding Universe Theory may be flawed, astronomers have discovered that supposedly distant galaxies look pretty much like those in our immediate neighborhood. Specifically, galaxies 10 billion light years away differ little spectrally speaking from those only a billion light years away. The point is that the distant galaxies should appear 9 billion years younger because their light took that long getting here. They look the same, and that fact could imply: (1 ) Galaxies mature rapidly and do not change much after a billion years; (2 ) Our cosmic time scale is all wrong; (3 ) There was no Big Bang and galaxies may have widely varying ages; or (4 ) None of the above. (Anonymous; "Most Distant Galaxies: Surprisingly Mature," Science News, 119:148, 1981.) Reference. Distant galaxies are anomalously blue. See AWF1 in our Catalog: Satrs, Galaxies, Cosmos.

Science Frontiers ONLINE No. 15: Spring 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Novaya Zemlya Effect Rarely, as the long polar night draws to a close, the sun will suddenly burst above the horizon weeks ahead of schedule. This is the Novaya Zemiya Effect, and it is basically a polar mirage. Even when the sun is still 5 below the horizon, its light can become trapped between thermoclines and be transmitted over the usual horizon. The atmospheric ducts act much like flat light pipes. In the Novalya Zemlya Effect the sun's image is grossly distorted, quite different from the high quality mirages sometimes seen over hundreds of miles in the polar latitudes.

... Science Frontiers ONLINE No. 16: Summer 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Earth-moon fission: a slight hint Although the Sm/Nd isotope ratios of the earth and the chondrites (a type of meteorite) seem pretty close in value, the possibility of a slight but significant discrepancy remains. If this small difference is confirmed, it would strongly imply that the earth's Sm/Nd ratio was shifted after the planet's formation. The most reasonable event that could shift this ratio is an long-debated earth-moon fission, wherein the earth's lighter surface material was somehow torn off to form the moon. (DePaolo, Donald J.; "Nd Isotopic Studies: Some New Perspectives on Earth Structure and Evolution," Eos, 62:139, 1981.) Comment. The moon's density is markedly less than the earth's , so the idea is not as wild as it seems. The hypothetical fission of Earth-Moon could have shifted the Nd isotope ratio in relation to that of the chondrites. From Science Frontiers #16, Summer 1981 . 1981-2000 William R. Corliss ...

... observed that our planet's environment has actually changed little down the eons despite solar variations. Lovelock's hypo thesis is that all terrestrial life -- animals, plants, termites, etc -- work sym biotically to maintain planetary temperatures, atmospheric constituents, etc., conducive to life, just like the termite's internal residents on a much smaller scale. The Gaia concept was restated by R.A . de Bie in a letter to Nature about the possibility of life in outer space. He observes that terrestrial life, according to Gaia-thought, will naturally develop a species that can carry life off the planet to new and safer environs. Humankind, of course, is the first attempt we know of to create such an agent. Other planetary systems might have differently constituted agents. (de Bie, Roeland A.; "The Ultimate Question," Nature, 295:8 , 1982.) Comment. To extend the biological analogy, the appearance of humankind represents the "fruiting" or "spore" stage of composite earth life. Humankind or some equivalent life form would thus be an inevitable development of any life colony in the broad and seething universe of galaxies.
