But, according to NASA's R. Bindschadler, an ongoing study of the Antarctic coast near the Ross Ice Shelf casts doubt upon this assumption of long-term stability. Measurements of one ice stream flowing down from the mountains to the sea in dicate a sudden unexplained, 20% reduction in speed over the past decade. Perhaps even more significant is that, even with this reduction in flow velocity, this particular ice stream carries ice into the sea 40% faster than ice accumulates up in the mountains. The sudden, rather large velocity change is alarming because it may signify widespread instability in the continent's icy mantle. Researchers state that there is even a chance that much of the Antarctic ice cap could collapse into the sea in the next few centuries -- a catastrophic event that would raise global sealevels by 6 meters! (Anonymous; "Antarctic Ice Potentially Unstable," Science News, 137:285, 1990.) Comment. In addition to looking at future consequences of collapsing Antarctic ice sheets, we should mark that what might happen in the future might also have happened in the past. Obviously, we refer to the often-discussed speculation that the Antarctic was nearly ice-free within historical times. In this connection, we cannot escape mentioning that remarkable ancient map of Piri ...

Usually consisting of two concentric circles centered on orthogonal axes, this cross design is found carved on rocks and in the floors of ceremonial buildings throughout Mesoamerica. Such a motif would ordinarily not evoke much comment, but here the figure is formed from many small, evenly spaced depressions so arranged as to hint at larger meanings. For example, many pecked crosses have 260 depressions, suggesting a calendric interpretation (i .e ., the 260-day Mesoamerican cycle). On some occasions the cross arms are astronomically oriented. In addition, the holes may have been used to hold pieces in ritual games similar to patolli. The pecked crosses are widespread and were apparently quite significant to the ancient Mesoamericans. Perhaps, the authors suggest, the figures had a composite astronomical, calendric, and ritual purpose. This would be consistent with the Mesoamerican cosmological belief that everything is interlinked and that the works of man must be, too.

These muffled detonations heard near the coasts of almost all the continents are believed by some to be caused by eruptions of methane from the seafloor. The same eruptions probably also account for the myriads of "pockmarks" found in the sediments of shallow seas. Whether this outgassing of methane comes from shallow accumulations of organic matter or from deep within the crust is still debated. Here, geophysics merges with biology. Recently, a group of researchers discovered a large (540 square meters) patch of chemosynthetic mussels in a brine-filled pockmark, at a depth of 650 meters, off the Louisiana coast. The mussels grew in a ring around the concentrated brine. The mussels harbor symbionts which consume the methane still seeping up through the brine from a salt diapir (a massive fingerlike intrusion 500 meters below the brine pool. The origin of some diapirs is not well-understood.) The mussels get the oxygen they require from the ordinary seawater covering the dense brine. Like the biological communities surrounding the "black smokers" and other ocean-floor seeps, the brine-filled pockmark community includes several species of shrimp, crabs, and tube worms. We have here another example of the astounding ability of lifeforms to take advantage of unusual, even ...

In fact, it was easy to find three examples of such processes from the literature collected from the past two months.

Taking a different tack, R.G . Jahn, at Princeton, has been experimenting with microscopic psychic effects, such as raising the temperature of a thermistor by a few thousandths of a degree or changing the separation of interferometer mirrors by a hundred-thousandth of a centimeter. Quite unexpectedly (at least to the conventional physicist) the mind seems able to cause such changes at will under controlled conditions. The changes are minuscule to be sure, but cause-and-effect is clear-cut according to Jahn. But don't say that psi power has now been scientifically proven. The effects vary from person to person and, for the same individual, from time to time. The fact that one cannot predict the occurrence of the effects has led Jahn to speculate that the phenomena are inherently statistical.

Take, for instance, a well-formed spiral galaxy, of which there are a great many. When astronomers measure the circumferential velocities of the stars, as they circle around the galaxy's hub, they find that all the stars orbit at about the same velocity, regardless of how far out from the hub they are. Their speeds do not drop off with increasing distance, as the velocities of the planets do in the solar system. This observation is anomalous itself, because it seems that the laws of orbital motion have been violated. We will save this anomaly for another day, the one we are after now is called: The Winding Dilemma. N. Comins and L. Marschall elaborate as follows: "Stars closer to the center of a spiral galaxy don't have as far to go to complete an orbit as stars located farther from the center. Thus, inner stars should orbit more frequently than outer stars, resulting in a spiral that gradually winds up as the galaxy ages. But observations of spiral galaxies at various distances -- and thus at different stages in their evolution -- have shown that this is not the case. Astronomers believe density waves, stochastic star formation, or perhaps a combination of both processes may sustain or regenerate the spiral pattern." Density ...

The cylindrical microfossils average 50 x 110 microns and are the size and shape of fecal pellets produced by microscopic animals today. Pellets occur in dark gray and black rocks that were deposited in the facies that also preserves sulfide minerals and that represent environments analogous to those that preserve fecal pellets today. Rocks containing pellets and algal microfossils range in age from 0.53 to 1.9 gigayears (Gyr) and include Burgess Shale, Greyson and Newland Formations, Rove Formation, and Gunflint Iron-Formation. Similar rock types of Archaean age, ranging from 2.68 to 3.8 Gyr, were barren of pellets. If the Proterozoic microfossils are fossilized fecal pellets, they provide evidence of metazoan life and a complex food chain at 1.9 Gyr ago.

Astronomers are sure it exists because its presence, though unseen, explains two anomalies: The high circular velocity of the stars and gas in the outer reaches of galaxies. Circular velocities should decrease with distance from the galactic center, just as planet velocities do in the solar system. They don't , so some gravitational force from some unseen mass must counterbalancing centrifugal force (mark that this is presumptious! The "force" need not be gravity.) Observations suggesting that galaxies formed when the universe was less than a billion years old. The gravitational pull of the visible mass is inadequate to cause this clumping so quickly in the history of the universe. Many candidates have been proposed to play the dark-matter role. One of the more popular possibilities is that vast sea of neutrinos pervading the cosmos -- if they really do display just a hint of mass. Two other candidates now on the table are so bizarre that we marvel at the ingenuity of the theorists. One involves exceedingly large particles, the other unbelievably tiny clumps of particles. At the "giant" end of the size spectrum are galaxy-size particles weighing only 10-24 as much as an electron, which is itself by no means large.

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

No one has ever been able to figure out any foolproof system to their occurrence or how to generate them all by formula. Some primes, such as 11 and 13, 17 and 19, etc., come in pairs; but most don't . And some formulas are particularly good at generating primes, but they all fail somewhere. One such formula was discovered by Leonhard Euler, the great mathematician: n2+ n+ 41 This formula works for n = 0, 1, 2,...39; but fails at n = 40. An interesting consequence of Euler's formula can be made apparent when all numbers from 41 to 440 are written in a square spiral, like so: All of the numbers on the diagonal indicated are Euler formula primes, even when the spiral is expanded to 20 x 20. However, when the 20 x 20 spiral is examined closely, many of the other primes -- those not generated by Euler's formula -- also tend to line up on diagonals. This is a most intriguing characteristic, one which goes far beyond the 20 x 20 array mentioned above.

Leys are supposedly the intentional spotting of megalithic sites along straight lines extending several kilometers. Some alignments occur through chance, but several leys seem statistically significant. The puzzle is why ancient peoples bothered to align their edifices -- assuming they really did. Most professional archeologists believe leys to be figments of the imagination of amateurs. This being so, they must be incensed by the claims made two weeks later in New Scientist. There, stimulated by the earlier report on leys, a retired engineer presented his measurements of the magnetic fields around the Rollright Stones. He maintained that he was able to magnetically detect several converging leys and, in addition, a spiral pattern inside the stone circle. A psychic accompanying him independently perceived the leys and spiral. (Devereux, Paul, and Forrest, Robert; "Straight Lines on an Ancient Landscape," New Scientist, 96:822, 1982.

Photoreceptors are sensitive to light but do not produce images. They are found in many groups of animals. Even humans possess photoreceptors besides their eyes; specifically, in the pineal gland and, perhaps, the knees. (SF#116, SF#117) The pineal gland (our "third eye") may have registered photons at some stage in our evolution, but it is now useless or adapted to other purposes. The arthropods, however, still find photoreceptors useful. Crayfish have them on their abdomens, where they initiate an escape response when illuminated. Additionally, the blind shrimp that collect around the glowing deep-sea vents have photoreceptors perched on their backs, presumably to guide them to their prey located around the luminous vents. Recently, the Japanese yellow swallowtail butterflies were discovered to sport photoreceptors on their genitalia. These I are used during mating to confirm the position of the female's ovipositor.(Arikawa, Kentaro; "Hindsight of Butterflies," BioScience, 51:219, 2001.) Barn-Owl auditory neurons multiple signals.

The individual shrimp in these sponge-sheltered colonies are not all alike. The noise-makers are the "soldier" caste, which wield big "fighting claws."

On one hand, stellar age theory assures us that stars in the globular clusters that pervade the universe were born about 15 billion years ago. On the other hand, new measurements of the distance to the Virgo cluster of galaxies are equally adamant that these objects are much closer than thought -- so close that, assuming the standard Big Bang model and the resultant expanding universe, the age of the universe may be as small as 8 billion years! In other words, the universe is younger than some of the stars in it; an obvious and painful dilemma for astronomy. How will this conflict between the two dominant astronomical paradigms play out? Many are betting that the Big Bang theory will require a major over-haul. Or more, as suggested in the next item. (Jacoby, George H.; "The Universe in Crisis," Nature, 371:741, 1994.

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. John Sulston, one of the researchers, says, "Within the lineage you can see the fossil of its past." (Marx, Jean L.; "Caenorhabditis Elegans: Getting to Know You," Science, 225:40, 1984.) Comment. Sulston's statement reminds one of "Ontogeny recapitulates phylogeny," ...

This fact does not mean that it is easy to understand. In fact, there are eight competing "interpretations" of quantum mechanics, none of which is completely convincing. No wonder, because quantum mechanics implies four characteristics of the universe that are seriously at odds with our everyday experience: The quantization of the properties of matter; The probabilistic nature of physical measurements; Entanglement; that is, the mysterious instantaneous connection of objects and processes across immense distances; and Superposition; for example, an electron is both here and there until we look at it! A. Zeilinger, University of Vienna, advances the idea that we can truly understand quantum mechanics only when we discover an underlying principle -- something akin to the concept of energy which led to the quantification of the laws of thermodynamics. (Incidentally. we only think we know what energy is, but it is a human construct and is not a physical dimension like mass or distance.) Zeilinger asserts that the underlying principle of quantum mechanics is the quantization of information. Every inquiry science makes into the nature of the universe, says Zeilinger, can be reduced to a yes-or-no question; i.e ., a 1 or 0. To a scientist, nature is really like a person on a ...

An equivalent situation would prevail in the brain if all sensory pathways and cells had fixed duties and memories to handle. If the portion of the brain dedicated to speech were damaged, as in a stroke, it could never repair itself. This dogma is now being challenged. A pertinent line of brain research is now underway at the Coleman Laboratory of the University of California in San Francisco, where Michael Merzenich and his associates are studying the brains of monkeys. "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. Perhaps the brain even stores duplicates of critical "programs"; i.e ., skills. Merzenich's findings go even farther. He finds that the parts of the brain associated with certain skills or data processing move and change shape ...

Could such vortices actually maintain their integrities for several minutes and thus produce the curious tubes of misty air and flapping sounds observed at the end of the Los Angeles airport runway? The answer seems to be YES, as confirmed below: "Wingtip vortices have a core diameter of 20 to 40 feet and, as they trail behind each wingtip, remain approximately two wingspans apart. Why don't they enlarge in radius and dissipate? The rapid acceleration at the outer edge of the vortex produces low pressure in the core, and this pressure differential creates enough centrifugal force to hold the system tightly together for three to seven minutes. After that, friction takes its course, breaking these stubborn twisters apart into mere turbulence."

Such features are not particularly rare in deep-sea-creatures, but we do have to briefly describe this grotesque fish to get a delightful anomaly.

Helfer, University of Rochester, noting the absence of extensive cratering on the northern plains of Mars, suggests that some 2-3 .5 billion years ago these plains were covered with oceans. These ancient seas, perhaps as much as 700 meters deep, protected the plains from direct impacts. Further, crater density counts for Chryse and the Martian highlands imply that Mars possessed a fairly dense atmosphere until about 1.5 billion years ago. In his Abstract Helfer speculates as follows: "With both early Earth and early Mars having similar atmospheric compositions and not too dissimilar atmospheric structures, it is reasonable to suppose that the warm Martian oceans, like the ancient oceans of Earth, would develop anerobic and aerobic photosynthesizing prokaryotes and structures like stromatolites. Their development might have changed the Martian atmosphere. Their fossils might be found along the fringes of the old oceans, the northern lowland plains." (Helfer, H.L .; "Of Martian Atmospheres, Oceans, and Fossils," Icarus, 87:228, 1990.) Comment. The Gaia influence is seen in the molding of the Martian atmosphere into something more conducive to the development of life.

These filaments emit radio energy just like the planetary radiation belts and are presumably held in the grip of a galactic magnetic field.

Now, it seems that the moon's "cold" emanations can also raise the earth's temperature. Explaining how the moon's phase can have any warming effect at all on the earth's atmosphere is difficult, because the infrared energy received from the moon is only 10-5 that in sunlight. Nevertheless, a slight but statistically significant temperature effect does exist. In one study, the microwave emission of molecular oxygen was measured by a polar-orbit satellite. These data gave meteorologists the temperatures of the lowest 6 kilometers of the atmosphere from all areas of the planet. The temperature difference between full moon and new moon was only 0.02 C, with the full-moon temperature being the higher.

They are not true compounds, but rather clathrates or inclusion compounds. They often form in huge masses in ocean-bottom sediments and, if disturbed by slumping or some other stimulus, can release immense quantities of gas bubbles. These gases rise to the surface, subdivided en route, and reach the surface as a huge upwelling of frothy, low-density fluid. A ship cannot float in such low-density fluids. If a large plume rose above the sea's surface, aircraft passing through it would lose engine power. Quoting the final paragraph: "Intermittent natural gas blowouts from hydrate-associated gas accumulations, therefore, might explain some of the many mysterious disappearances of ships and planes -- particularly in areas where deep-sea sediments contain large amounts of gas in the form of hydrate. This may be the circumstance off the southeast coast of the United States, an area noted for numerous disappearances of ships and aircraft."

Before Voyager, Neptune's spin period was believed to be about 17 hours. This was just the spin rate needed by theorists to explain why Neptune radiates much more heat than Uranus. It seems that spin rate is related to the mixing of a planet's molten innards, which in turn affects the rate at which heat reaches the surface where it is radiated away. With Neptune's period now pegged at 16 hours by Voyager's measurements, the mixing-cooling theory is in trouble. The magnetic-field situation is in even worse shape. When planetary scientists found that Uranus' magnetic field was tilted 60 from the axis of rotation, they worried a bit but didn't think that this one exception would overthrow the favored dynamo theory of field generation. After all, the magnetic fields of Jupiter, Saturn, and earth are reasonably well-behaved. But Neptune's field is now found to be misaligned by 50 ! The confidence of the planetologists has now been shaken. What, if anything, is different about Neptune and Uranus? It may just be that we don't really know how the magnetic field of any planet is generated. (Kerr, ...

The textbooks say that this alien DNA is destroyed during digestion. Otherwise, it might "somehow" be incorporated into our own DNA, leading in time to our acquisition of some bovine characteristics! You'll recall that cannibals thought to acquire the virtues of their slain enemies by grabbing a bite or two! But this all sounds pretty farfetched, doesn't it? Maybe not. When W. Doerfler and R. Schubbert, at the University of Cologne, fed the bacterial virus M13 to a mouse, snippets of the M13's genes turned up in cells taken from the mouse's intestines, spleen, liver, and white blood cells. Most of the alien DNA was eventually rejected, but some was probably retained. In any event, alien DNA in food seems to make its way to and survive for a time in the cells of the eater. (Cohen, Philip; "Can DNA in Food Find Its Way into Cells?" New Scientist, p. 14, January 4, 1997.) Comment. We are only half-kidding when we ask if food consumption could affect the evolution of a species. After all, our cells already harbor mitochondria, which are generally admitted to have originally been free bacteria that were "consumed" by animal cells. The process even has a name ...

"The discovery, made by psychologist Diana Deutsch of the University of California at San Diego, concerns pairs of tones that are a half octave apart. When one tone of a pair, followed by a second, is played, some listeners hear the second tone as higher in pitch than the first. Other people, hearing the same tones, insist that the second tone appears to be lower in pitch." Other differences in perception also exist in the world of music.

Science Frontiers ONLINE No. 122: Mar-Apr 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Now We Know Why!Circa 1950, physicist E. Fermi observed that our galaxy measures about 100,000 light years across, and that a spacefaring race could cross it in only 100 million years, even if their starships poked along at only 1/1 ,000 the speed of light. Since our galaxy is about 10 billion years old, the very reasonable question is: If other intelligences (ETs) exist in our galaxy, why haven't they found us by now? Actually, many ETs from many different cultures should be stopping by frequently. J. Annis, an astrophysicist at Fermilab, believes he can explain the apparent dearth of ETs. The problem is gamma-ray bursts (GRBs). They are so powerful that they sterilize those galaxies in which they occur. Presently, GRBs occur in each galaxy about once every 100 million years, but theory suggests that they were much more frequent in the past. As a consequence, by the time intelligent life evolves anywhere and figures out how to build spaceships, they are zapped by a GRB. Perhaps some do begin exploration of their galaxy, but they don't get very far. (Matthews, Robert; "Sorry, We'll Be Late," New Scientist, p. 16, January 23, 1999.) Comment. Any reader of science fiction can come up with other explanations: (1 ) ETs have been ...

At such places, car drivers can stop, put the car in neutral, release the brakes, and the car will seem to roll uphill. Some of the spots mentioned were: On route A719, in Ayrshire, there are "special warning signs because of the likelihood of meeeting cars coasting uphill backwards, as baffled drivers are confused by their senses." Near Neepawa, Manitoba, one finds a road named Magnetic Hill. Northern Portugal. Here, bikers have to pedal hard to go downhill ! Lake Wales, Florida, is the location of Spook Hill, described in SF#73 and SF#79, and, of course, our book Science Frontiers (To order see here .

Since the woman wore a hearing aid in each ear, it was first thought that she might be picking up local radio stations; but a check showed that none was playing the repertoire she reported. Mostly she heard songs from the 1930s and 1940s. Finally, it was discovered that she was taking 12 aspirins a day. When this dosage was halved, the music stopped. Doctors have known that too much aspirin can cause ringing in the ears, but this is the first time that specific songs were induced. (Anonymous; "Stop the Music," Science News, 128:168, 1985.)

Some of the scenery revealed by this sonar challenges conventional geological wisdom. To illustrate, the British ship Farnella has been mapping the floor of the Gulf of Mexico with its GLORIA II side-scan sonar. Hundreds of new salt domes, submarine channels, and landslides have been recorded. A big surprise was the discovery of large fields of sand dunes in 3000 meters of water. Similar dune fields were found in the Pacific in 1984. G. Hill, of the U.S . Geological Survey has ventured, "There's something going on in deep water that people just aren't aware of. " (" A Systematic Sounding of the Sea Floor, " Science News, 128:191, 1985.) (At issue here is how sand dunes are formed in such deep water. Are they the consequence of colossal bottom currents, perhaps set in motion by huge earthquakes of some other natural catastrophe ? Is it possible (gasp!) that the dunes were not formed under water at all ? The area involved also boasts salt layers and submarine channels and canyons, both of which are not well-explained.
