We humans know to our dismay that we have the capacity to modify the earth's environment, but could we perhaps exercise better judgment and terraform Mars? C.P . McKay et al have looked into this possibility: "From our analysis, one could propose the following sequence of events: production of CFCs (or other greenhouse gases) starts on Mars and the surface temperature warms up by about 20 K. The regolith and polar caps release their CO2 and the pressure rises to 100 mbar. One of two things could then happen. If there were large regolith and polar CO2 reservoirs, the pressure would continue to rise on its own. If these were absent, the CO2 pressure would stabilize, and additional CO2 would have to be released from carbonate minerals. At this point (perhaps between 100 and 105 years) Mars may be suitable for plants. If there was a mechanism for sequestering the reduced carbon, these plants could slowly transform the CO2 to produce an O2-rich atmosphere in perhaps 100,000 years. If sufficient N2 could also be released from putative soil deposits, and the CO2 level kept low enough, then a human- breathable atmosphere could be produced. (McKay, ...

ESP experiences are reported more frequently, and accuracy of laboratory ESP is more accurate, on days of relatively quiet GMF activity. On the other hand, there are indications that a complementary paranormal process, psychokinesis, may be enhanced by high GMF activity. We conducted retrospective analyses of possible relations between GMF activity and (a ) electrodermal activity (as an index of sympathetic autonomic activity), (b ) rate of hemolysis of human red blood cells in, (c ) attempted distant mental (i .e ., psychokinetic) influence of electrodermal activity, and (d ) attempted distant mental (psychokinetic) influence of rate of hemolysis. For each of these four measures, high activity was associated with high GMF values, while low activity was associated with low GMF values. The relations were statistically significant for three of the four analyses and showed a consistent trend in the fourth."

... In many parts of the world, older rocks are found on top of younger rocks. Ob-viously the Principle of Superposition is contradicted in such situations. Two possible explanations exist for these inverted strata: (1 ) The dating of the rocks is incorrect; or (2 ) Geological forces somehow slid the older rocks over the top of the younger rocks. Few mainstream scientists give any thought to the first possibility because it implies that evolution did not proceed as presently envisioned. (Rocks are often dated by their fossil contents.) So, geologists are left with the problems of sliding great masses of rock over rough surfaces for great distances. Sketch of the forces acting upon a thrust block being pushed by a wedge-shaped driver Low-angle thrust faulting is not a trivial geological process. To illustrate, the Lewis Overthrust in Montana and adjacent Canada involves the shoving of a block of old strata hundreds of feet thick, hundreds of miles long, over younger rock for a distance of possibly 50 miles. In contemplating such overthrusts, one immediately comes face to face with the Mechanical Paradox. Brief-ly, given the coefficient of friction between the layers of rock, the weight of the thrust block, and the mechanical strength of the rock being pushed, it can be shown that pushing the thrust block at the rear edge will crush it long before it begins to slide. For nearly a century, geologists have been trying to resolve this Mechanical Paradox. Three potential solutions have been proposed: (1 ) Lubricate the sliding surfaces with water under high pressure (the ...

Neither article mentioned the work of the other! Both groups of scientists processed massive quantities of earthquake records to form "seismic images" of structures deep in the bowels of the earth. (The technique is called "seismic tomography.") Both groups have discerned huge slabs of crust that were once on the planet's surface but were subsequently thrust (" subducted") down under the continents. These slabs are now hundreds of kilometers below the surface, and they have dragged water along with them. In fact, their water inventories may rival today's surface oceans; they may even have been surface oceans themselves millions of years ago before they descended into the infernal regions. Only a few years ago, all geologists maintained that all water in subducted slabs was squeezed out of the rocks by immense pressure and later reappeared at the surface as volcanic steam. Deep ocean #1 . G. Nolet and A. Zielhuis, Princeton seismologists, report a huge reservoir of water about 900 kilometers under present-day Europe.

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.

The best explanation conventional geology has come up with is that they were formed some 2.5 billion years ago by geological processes not in operation today. G. Harper, however, thinks that these Wyoming rocks look very much like some of the slices of ocean crust (terranes) that continental drift's conveyor belt has plastered against North America's west coast. The conveyor belt is, of course, the ocean floor that dives under the continent. The more he looked, the more Harper was convinced that there, in the middle of the continent, was a substantial chunk of ancient ocean crust. The implications: continental drift and terrane plastering have been in operation for billions of years: ". .. from their very beginnings continents have been built up from the bits and pieces of plate tectonics."

The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried organic matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C.

This is one reason why cold fusion got the cold shoulder from most physicists. Now for the "however" that is the hallmark of Science Frontiers : "Thirty years ago, Otto Reifenschweiler was searching for a compound which could protect Geiger-Mueller tubes from damage when they are first ionised. He found the compound, which became a money-spinner for Philips, in a mixture of titanium and radioactive tritium. He also discovered that as the mixture was heated, its radioactivity declined sharply. No process known to physics could account for such a baffling phenomenon: radioactivity should be unaffected by heat. Nevertheless, as the temperature increased from 115 C to 160 C, the emission of beta particles fell by 28%." Reifenschweiler and his colleague, H. Casimir, put this discovery on the backburner and concentrated on the Geiger-Mueller tubes. The recent furor over cold fusion impelled them to resurrect the work and publish it in the January 3 issue of Physics Letters A . Is there a new phenomenon here? Is it relevant to cold fusion?

The review, however, is expansive and provides some facts about synesthesia worth passing on to our readers. Syesthesia is an "oddity" of human perception in which words, musical instruments, objects, concepts, evoke sensations sharply different from what is actually being processed by the brain. For example, specific musical tones elicit specific color sensations; that is, B-flat evokes the color green; A-sharp, yellow, etc. Or the phenomenon may be more complex, with Mozart being green; Wagner, red, etc. Most "synesthetites" seem to experience colors, but geometrical figures sometimes appear in response to particular stimuli.

Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Sinister Development In Ancient Greece The unprecedented genius of Ancient Greece remains unexplained. Why the sudden surge of "civilized" activities: drama, poetry, philosophy, mathematics, and even science? It was all because the Ancient Greeks developed an alphabet that included vowels in addition to the consonants. The Greek language became a full phonetic representation of language. The left side of our brain, it seems, is much more capable than the right in matters phonetic. In contrast, other forms of writing in the ancient world, such as hieroglyphics and vowelless alphabets, are better handled by the right side of the brain. (As an aside, it is interesting that, in the modern world, Japanese and Chinese are better processed by the right side of the brain, while the phonetic representations of language, such as English, are handled better sinistrally.) Back in Ancient Greece, the new alphabet shifted language activities to the left side of the brain. According to J.R . Skoyles, this "unlocked" left-brain competences that had previously been analogous right-brain competences. The newly liberated competences involved rational, analytical, and logical faculties. Thus from the addition of a few vowels sprang Ancient Greece and, in time, modern civilization.

Fox, at the Institute for Molecular and Cellular Evolution, University of Miami, has been experimenting with possible precursors of life. So-called "microspheres" are hot items in Coral Gables these days. Fox and his colleagues make microspheres by preparing a heated stew of various amino acids. These amino acids form long polymer chains spontaneously. Then, when water is added and the mixture reheated (or processed in some other way), the polymers organize themselves, again spontaneously, into spheres a few microns in diameter. Each sphere consists of a two-layer membrane with residual material trapped inside. Although thicker, the microsphere membrane is very similar to the lipid bi-layer enclosing normal living cells. The relatively stable microspheres could, in theory, have formed sheltered environments for the evolution of the more complicated parts of living cells. The microspheres absorb sunlight and, with the addition of this energy, display some of the electrical characteristics of biological neurons, like those in the brain. The implication is that some components of "mind" may have existed in the very earliest life forms. (Peterson, Ivars; "Microsphere Excitement," Science News, 125:408, 1984.) Comment.

The scientific "instruments" here are the cooling lava flows. As they solidify from the outside in, a process taking about 2 weeks for a 2meter-thick flow, the lava is magnetized in the direction of the field prevailing at the moment of solidification. We would thus have a 2-week continuous record of the behavior of the earth's field. Ordinarily, we would not expect to see very much change in 2 weeks; even a reversing field is thought to take thousands of years to complete its flip-flop. However, at Steens Mountain, when the field reversed 15.5 million years ago, the lava flows suggest that the field's axis was rotating 3-8 per day -- incredibly fast according to current thinking, in fact a thousand times faster than expected. The conundrum (one might call it a scientific impasse) arises because the flowing electrically conducting fluids that supposedly constitute the earth's dynamo would have to flow at speeds of several kilometers/hour.

"Sharply angular boulders as large as 320 kg [700 pounds] sit on the Racetrack Playa, Death Valley, California; trails leading to them indicate that the rocks have moved large distances. The process has never been witnessed. Although high winds and a wetted surface seem necessary, controversy persists about the need for other conditions, especially ice sheets. On the basis of experiments with a wetted Racetrack surface (soft mud about 3 cm deep), we find the effective coefficient of friction to be surprisingly high, about 0.8 . Movement by wind alone of moderate-sized (20 kg) rocks with cubic shape requires sustained winds close to the ground of about 80 m/s (about 180 mph). Larger flat-lying rocks require much higher winds." The authors of this paper, J.B . Reid, Jr., et al, precisely mapped a large number of the enigmatic tracks.

The colliding particles usually fragment one another and in the process release a variety of subatomic debris and energy. Large arrays of detectors surrounding the collision site record the particles as they streak away. Usually the escaping particles can be easily identified; but in 1983 nine strange events were recorded, and more have occurred in 1984. Something both invisible and inexplicable carried off large amounts of energy during these "strange" events. Physicist Carlos Rubbia, of CERN and Harvard, said: "There is no sensible way to explain the missing energy by known particles." Some theorists believe that these anomalous events will be explained only by invoking what is termed "supersymmetry" theory. Supersymmetry predicts that twice as many particles as those known today must exist. Already, physicists are rushing to name the new, though unverified particles.

It must be complete and perfect to work at all. New high-speed photos and related research demonstrate that: "The ejection system of the beetle shows basic similarity to the pulse jet propulsion mechanism of the German V-1 'buzz' bomb of World War II." What the beetle has "evolved" is an intermittent explosive process that fires about 500 pulses per second. The explosive energy comes from the mixing of two separate fluids (hydroquinones and hydrogen peroxide with oxidative enzymes). (Dean, Jeffrey, et al; "Defensive Spray of the Bombardier Beetle: A Biological Pulse Jet," Science, 248:1219, 1990.) Comment. The fundamental question is, of course, how can many, small, random mutations contribute to the development of the mechanisms of the pulse jet, its two fuels, the pumps, the fuel reservoirs, the control system, etc., when only the complete, perfected system has survival value.

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 ...

Perhaps a more profound question is: Why do sea-shells need to be pretty in the first place? After all, most (but not all) of the shell owners do not have eyes with which to appreciate their handiwork! However, mathematicians and computer modellers do have eyes. 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!

These dark radiohalos or "pleochroic" halos have specific radii and can be used to identify the radioisotopes that produced them. So far, so good; but: "The fact that fully formed, optically visible internal radiohalos in diamonds are now presented casts a considerable shadow over current theories of diamond genesis." Actually, the radiohalos pose three challenges to diamond-genesis theory. Problem 1. The half-lives of the halo-creating radioisotopes are measured in thousands of years rather than the billions prescribed for crystallization. In fact some of the half-lives are only minutes or days long. M.H . Armitage comments: "How could these halos become imprinted if the formative cooling processes involved require such lengthy intervals?" Problem 2. The radioactive impurities producing the radiohalos are very tiny -- about 2-4 micrometers in diameter -- and are highly concentrated. Armitage continues: "What is most difficult to understand is that many of these inclusions and impurities have much lower melting and boiling points than the diamonds in which they are found." Why did the impurities fail to disperse as the higher-melting-point diamond matrix surrounding them slowly cooled down the eons? Photomicrograph (100x) of hollow tubes in a diamond Problem 3. Some diamonds contain a strange, rectangular latticework of radiation-stained hollow tubes. Some of the tubes terminate in radiohalos; some do not. Some reach the crystal surface; most don't . What are these tubes ...

... . "Theory, anatomy, neural circuitry, function, and behavior now support a hypothesis of the forked tongue as a chemosensory edge-detector used to follow pheromone trails of prey and conspecifics [especially the opposite sex]. The ability to sample simultaneously two points along a chemical gradient provides the basis for the instantaneous assessment of trail location." The framer of this hypothesis, K. Schwenk, adds that the forked tongue and, obviously, the muscles and neural circuitry to use it properly, have evolved independently at least twice, possibly four times. (Schwenk, Kurt; "Why Snakes Have Forked Tongues," Science, 263:1573, 1994.) Comments . One can compare the forked tongue to binocular vision. Both require the parallel evolution of impressive infrastructures of data processing "equipment." From Science Frontiers #93, MAY-JUN 1994 . 1994-2000 William R. Corliss ...

... is ever the "however": "Arnd Schreiber, Doris Erker and Klausdieter Bauer of the University of Heidelberg have looked at the proteins in the blood serum of megabats and primates and found enough in common to suggest a close taxonomic relationship between the two groups. (Biological Journal of the Linnean Society, 51:359)" An explanation might be that the similarities between the microbats and megabats represent adaptations to similar environmental niches rather than a common ancestry. (Timson, John; "Did Bats Evolve Twice in History?" New Scientist, p. 16, June 4, 1994.) Comment. Does the black box labelled EVOLUTION contain a special subprogram for converting hands into membaneous wings whenever it seems profitable to do so? Or are we somehow missing a different sort of evolutionary process, perhaps something akin to the "directed evolution" suggested by some experiments with bacteria? (SF#64) The possible separate evolutions of micro- and megabats is covered in more detail in BMA41 and BME1 in Biological Anomalies: Mammals I and II, respectively. To order, visit here .

... field, is a spectacular new form of lattice-induced nuclear energy whose mechanism is still poorly understood -- as the mechanism of low-temperature superconductivity was for decades. That the nuclear products that have been found so far are incommensurate (by conventional theory) with the non-chemical-magnitude excess energies simply means that the results have to be explained by new physical mechanisms." Of opposite polarity were remarks by J.R . Huizenga, author of the debunking book: Cold Fusion: The Scientific Fiasco of the Century : "In contrast to Mallove's declaration that cold fusion is a "spectacular new form of lattice-induced nuclear energy," I conclude that there is no persuasive evidence to support this far-out claim. Instead, cold fusion as a nuclear process producing watts of excess heat is more likely than not to be an example of pathological science." Of historical interest in this collection of correspondence in Physics Today was S. Bashkin's mention of the 1926 experiments of F. Paneth. His results were essentially identical to those of S. Pons and M. Fleischmann that began the present cold fusion furor. Paneth detected helium after passing an electrical current through hydrogen-laden palladium! But he later retracted his conclusions.

... nightmarish. But pleasant, controllable lucid dreams are the general rule. If you can't seem to get into lucid dreaming, apply to the Lucidity Institute, where you can purchase a Nova-Dreamer machine for $275. Thus armed, you can enter that Never-Never Land anytime you want. But how does one know he or she is dreaming lucidly? There is a simple test that is not only strange but probably anomalous. During your dream find a shop or traffic sign, even a dollar bill or newspaper. Then, find a word of four or more letters. Look away, and then look back. If the word has changed when you look back, you are in a lucid dream. For reasons unknown, the brain centers controlling lucid dreaming cannot consistently process words of more than three letters!
