Recent radio astronomical studies of the Milky Way reveal long filaments of ionized gas about 150 light years long curving up out of the galactic disk, at a point about 30,000 light years from earth. These filaments emit radio energy just like the planetary radiation belts and are presumably held in the grip of a galactic magnetic field. There have been previ-ous hints of a weak and disorganized galactic magnetic field, but this is the first evidence for a strong polar field in our own Milky Way or any other galaxy. The unexpected filaments were discovered by in a study of star formation in the core of the Milky Way. The radio energy emitted by the belts was originally thought to come from the galactic machinery that makes new stars; but now it looks like that machinery is not grinding out nearly as many new stars as once thought.

To be sure, corals built the Great Barrier Reef and beavers left their mark on the hydrology of parts of Canada and the U.S .; but termites!? It seems that in southern Africa this industrious insect is responsible for enormous striped patterns of ridges and vegetation bands. These amazingly regular patterns are caused by alternating low ridges and gullies. The ridges are about 2 meters high, up to a kilometer long, and separated by about 50 meters. The ridges themselves are closely spaced termite mounds. Just why the termites choose to build their mounds in long rows is an unanswered question. And how do the termites maintain strict parallelism, especially since they are blind? How could termites in one mound know how their neighbors in the nearest ridge, 50 meters away, are building their mounds? Anyway, the ridges help channel the flow of water and thus the growth of vegetation, giving immense swathes of country a corrugated appearance. (Sattaur, Omar; "Termites Change the Face of Africa," New Scientist, p. 27, January 26, 1991.) Comment.

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. 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.

From this, they carved a lion with a human head out of the soft natural rock. Once the soft limestone was exposed, the rain and atmosphere began to erode it. R.M . Schoch, a Boston University geologist, studying the weathering patterns on the Sphinx, found signs of water action up to 8 feet deep in the front and sides of the colossal statue. Other structures in the vicinity, made from the same limestone, supposedly at the same time (about 2500 BC), do not display such deep erosion. Based upon the depth of the weathering, Schoch dates the Sphinx at 5000-7000 BC -- much older than the mainstream date of 2500 BC. In fact, Schoch opines that work on the Sphinx could have begun as early as 10,000 BC. Egyptologists, of course, will have none of this. C. Redmount, a Univerisity of California archeologist specializing in Egyptian artifacts, said, "There's just no way that could be true." Some non-establishment archeologists, such as A.

... now time to broach the subject of the quantization of life itself. The reader can blame Stanley only for the stimulus and his discussions of speciation and the discontinuous (quantized?) fossil record. (Campbell, Neil A.; "Resetting the Evolutionary Timetable," BioScience, 36:722, 1986.) Comments. When we suggest quantization in biology, two phenomena come to the fore: 1. The obvious splitting of life into well-defined states -- the species -- as defined morphologically and/or by the genetic code; and 2. The gaps in the fossil record, which imply a frequent lack of transitional forms from one species to another. As Stanley asserts repeatedly in his interview, the fossil record is actually quite good in many places, despite the long-voiced claims of the gradualists that transitional forms do not exist merely because of the deplorable state of the fossil record. In physics the analogous phenomena would be: (1 ) The chemical elements and their isotopes (or an atom's energy levels); and (2 ) The lack of transitional forms. Straining the analogy still further, the evolution of one species into another simply means that life-as-a -whole moves from one quantized state to another. There need be no transitional forms, just as there are none when elements are transmuted or galaxies change redshifts (? ). Atomic physicists, long since mystical about this whole business, no longer try to explain what happens during a quantum transition. The only observables are the quantum states -- or species ...

No one has been able to predict its future course accurately. Already this maverick planet is drifting off the orbit predicted just 10 years ago using the best data and solar-system models. All of the outer planets, in fact, confound predictions to some degree. In addition, some long-period comets have anomalous orbits. Astronomers have been aware that something was wrong for decades and anticipated finding a trans-Neptunian planet large enough to perturb the outer solar system. The discovery of Pluto did not help matters; it is much too small. The most popular explanation of the orbital anomalies relies on a large, still-undetected planet, possibly 3-5 times the mass of the earth, swinging sround the sun at some 80-100 Astronomical Units. But many have searched and no one has found anything. Planet-X , as it is often called, is just another bit of "missing mass." Thomas C. Van Flandern and Robert Harrington propose that all the obvious orbital damage in the outer solar system is the result of a single encounter between Neptune and another body, call it Planet X if you wish, that was passing through the outer reaches of the solar system.

(From: Ancient Structures) As a matter of fact, there is little mystery here despite what you read in the popular magazines. The Egyptian workers simply dribbled quartz sand beneath the copper saws and drills. This abrasive is harder than the mica and feldspar components of granite but not the quartz. Nevertheless, granite will yield slowly to the abrasive, as do the copper tools themselves. In 1999, D.A . Stocks tested the efficacy of copper saws and drills on the granite in the Aswan quarries 500 miles up the Nile. The copper saw in his test was 1.8 meters long, 15 centimeters in depth, and 6 millimeters thick. Stocks experimented with both wet and dry sand and smooth and notched saws. In one test, workmen cut a slot 3 centimeters deep and 95 centimeters long in14 hours. It was slow work, but the ancient Egyptians had plenty of time and manpower. In the same experiment, the copper saw blade was ground down 7.5 millimeters. Overall, dry sand with a smooth blade worked best. Similar tests with a tubular copper drill were also successful.

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.

Thousands of Mexican sellos (seals), both of the cylinder and flat types, have been collected in the world's archeological museums. Many bear striking designs, like that of the heron shown below. For too many years, archeologists have considered these designs to be only designs. But with more discerning examination, bolstered by knowledge of ancient Old World alphabets, it now appears that these seals incorporate many letters from Libyan, Iberian, Punic, and other alphabets. Since many of the Mexican sellos date back to 1200 BC, the implication is that Old World-New World contacts occurred long before the Christian era. But, asks G.F . Carter in his long article on the sellos, if the ancient peoples of Mexico and Central America did absorb Old World symbols, "Why was the alphabet not developed instead of the clumsy hieroglyphics?"

The above quotation is the lead paragraph in a long BioScience article that details the consternation Cairns' results have created in the biological community.

The long history of supposed encounters with demons, witches, fairies, UFOnauts, and sundry fantastic creatures led Pontolillo to conclude: "From the preceding examination of the phenomenon's many aspects, it is apparent that alien abuctions are the continuation of an ancient, ongoing cycle of religio-mythic beliefs. The 'seed events' consist of routine medical and gynecological procedures, hypnagogic and hypnopompic (sleeprelated) imagery, and causative traumas such as sexual assault.

It is a Neolithic figure (5000-7000 years old), deeply engraved on rocks along the River Blaka, in Niger, Africa. Here, the ostrich definitely appears to be loaded with cargo that is strapped on.

In the Table of Contents, we see words concerning this article that we never thought would be permitted in a mainstream science magazine. After first noting that 10 years ago it was generally agreed that all organisms evolved from a single ancestral cell that existed about 3.5 billion years ago, there comes the assertion that the Tree of Life: "is far more complicated than was believed and may not have had a single root at all." The article proper relates how the Tree of Life has its own evolutionary history. Twenty years ago, scientists had that single ancestral cell splitting into two main trunks: the prokaryotes (bacteria) and the eukaryotes (every-thing else). More recently, a third trunk has been grafted onto the Tree; namely, the archaea (microorganisms that look like bacteria but possess markedly different genes). The archaea favor extreme environments and, curiously, are more closely related to you and me than are the bacteria. But according to this article (by W.F . Doolittle), the triple-trunked Tree of Life is simplistic. One reason for this is that genes, once thought to flow only from parent to progeny, are now known to travel laterally. Species barriers are broken. Genes jump from trunk to trunk, from ...

Not to worry, say the modern-day Technocrats, we will launch nucleararmed rockets that will nudge such cosmic threats into harmless trajectories. These Pollyannas are presumptious. They assume that asteroids are hard, cohesive objects that will be shoved aside by a few megatons of explosive energy. There are two things wrong with this idea, and these reveal how radically our ideas about the nature of asteroids have changed in just 10 years. First, most astronomers will now agree that asteroids are orbiting rubble piles rather than monolithic objects. For example, the near-earth asteroid Mathilde, 53 kilometers in diameter, has a density of only 1.3 grams/cubic centimeter. Its porosity must be greater than 50%. It is not a hard, coherent object. Instead of a bullet, it is more like a cloud of shotgun pellets. It would be hard to divert all this debris with a nuclear blast. To make matters worse, asteroids like Mathilde are stickier than a cloud of buckshot. This fact is deduced from photos of asteroids showing many to be marked by huge craters ...

The Oort Cloud of comets, like the unseeable black holes, are given substance only by the effects they have on other solar-system denizens and seeable cosmic objects. But there may be another cloud of comets that we can view directly. It is called the Kuiper Cloud (after G. Kui per). It is concentrated in the plane of the ecliptic just beyond the orbit of Neptune.

He has analyzed secondary dental traits (number of roots, bumps, etc.) of 12,000 individuals from around the world - both ancient and modern.

A preliminary analysis by Michael Mumma, of Goddard Space Flight Center in Maryland, and his colleagues. indicated that processes analogous to optical pumping in laboratory lasers were taking place and led to the coining of the term 'natural lasers.' Now, Deming and colleagues from the Goddard team have taken new observations of emission from Mars and Venus at wavelengths near 10 micrometers. and modelled them to show that stimulated emission -- the effect which makes lasers so powerful -- accounts for up to seven per cent of the total emission. This is not a large amplification factor by laboratory standards, particularly for a CO2 laser. But, the authors speculate that the sheer size of the natural lasers could make them useful tools in the future for communicating with distant civilizations beyond our own planetary system." The atmospheres of Mars and Venus are almost pure CO2 . The CO2 molecules are excited by the absorption of energetic solar photons; then, thermally emitted photons at about 10 micrometers from lower reaches of the atmosphere collide with the excited molecules, stimulating them to emit another 10-micrometer photon, thus doubling the number of photons. This is typical laser action. ...

A famous flare example was observed and reported in 1900 by A.E . Douglass, at the Lowell Observaory. The popular press quickly announced that the Martians were signalling us. Actually, this assumption was quite understandable because in those days the newly discovered Martian "canals" were in everyone's thoughts. Most scientists, however, rejected the signal notion preferring to attibute the flare to the specular reflection of sunlight from snowy peaks on Mars. But they were wrong, too. Close-up inspection by modern spacecraft has revealed no snowy peaks or large bodies of water on Mars that might mirror the sun. But another possibility has now come to the fore. The Martian flares could be reflections of sunlight from flat, hexagonal crystals of water ice in the thin Martian clouds; the same crystals that create some of the solar halos and sun dogs seen on earth. That this sort of specular reflection does occur was demonstrated on June 7, 2001, when a flare was actually photographed in the area of Edom Promontorium. The photography was possible because scientists had been watching this spot intently -- with cameras at the ready -- because a well-observed flare had occurred at this location in 1954, and ...

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!

However, E.R . John and his colleagues have confounded such thinking. They have prepared metabolic memory maps of cats' brains using carbon-tagging. In this way, they discern which parts of the brains have been activated during the recall of an element of memory. Such experimentation has demonstrated that huge numbers of brain cells actively participate in the recall of a simple thought. John stated, "I thought we'd find maybe 20,000 to 40,000 cells involved in the learned memory....The shock was that it was so easy to see wide-spread metabolic change....The number of brain cells [between 5 million and 100 million] involved in the memory for a simple learned discrimination made up about one-tenth of the whole brain." The findings of John et al are hotly contested by some brain researchers. One obvious conflict is that if up to 100 million brain cells are involved in storing just one simple memory, the brain will quickly use up all available cells. It must be that individual brain cells can participate in the storage of many different memories. The conventional mem-ory-trace theory would have to be replaced by a new type of memory architecture.

Two such cells abut the parasitic filament. The small black circles are parasitic cell nuclei which, when confronted with a red alga cell, become wrapped in small "conjuctor cells" which are then somehow transferred to the host cell on the right. The actual transfer involves the formation on the host cell wall of a sort of dimple called a "secondary pit connection." (Why this forms is not known.) Once inside the host cell, the parasite nucleus and/or the cytoplasm transferred with it dramatically reprograms host cell operations. The host cell shifts into highgear food production, enlarging up to twenty times its normal size. The host cell wall thickens, its nuclei (large black circles) and chloroplasts multiply. Adjacent cells (left) remain unaffected. (Lewin, Roger; "New Regulatory Mechanism of Parasitism," Science, 226:427, 1984.) Comment.

Sophisticated music predates the advent of modern humans by tens or hundreds of million years. Whales and birds filled the ocean and primeval forest with song long before our hominid branch sprouted on the Tree of Life. As a matter of fact, our closest relatives, the great apes, sing not at all. Somewhere in the hominid genome "music" genes reside, unexpressed in the apes, but somehow triggered into activity in the human line. We have learned recently that the Neanderthals manufactured bone flutes as far back at 53,000 years. They may not have been able to speak to one another in words, but they had the language of music. Their music, and ours, may have been entrained in genes inherited from nonhominid ancestors that lived 60 million years ago, but which have been suppressed in primates until Neanderthals and modern humans came along. You may wonder where this argument is taking you. It goes back at least 60 million years to when the cetacea (whales and dolphins) split off from the evolutionary track leading to humans. It may even go back farther to when birds split away from the reptilian line. The music of birds and whales incorporate some of the complexity and sophistication of Beethoven's Fifth.

Although its shoreline in complex, there is a deep channel about 2 kilometers wide with steep sides running lengthwise along the lake floor. When wind blows across the lake's surface, wind-drag pushes surface water downwind. When the wind stops or changes direction, the piled-up water is freed, and standing waves are set up as the water sloshes back and forth in the lake basin. These waves are called "seiches." Lakes usually have characteristic periods of oscillation. For Lake Champlain, it is 4 hours, with amplitudes measured only in centimeters on the surface of the water. What makes Lake Champlain of more than usual interest is the presence of a second seiche, an internal phenomenon not visible on the surface. In the summer, Lake Champlain is stratified with a thermocline separating a layer of warm surface water from much colder deep water. You can only "see" the thermocline if you lower a thermometer into the water. This thermocline also exhibits seiches, but they are startlingly different from those on the surface.

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.

Carneiro, a Brazilian physicist, proposed a way to get rid of this natal singularity but retain the expanding universe. First, he assumes that the universe has been around for an indefinitely (infinitely?) long time, thereby eliminating the problem of origin. Furthermore, this universe was rotating. About 11 billion years ago this spinning universe was transformed into the expanding universe we see today via that clever cosmologists' ploy called a "vacuum phase transition." Carneiro shows how the rotation of the universe-as-a -whole was converted into overall expansion in a paper submitted to the journal Classical and Quantum Gravity . But even if all of Carneiro's equations check out, angular momentum still had to be conserved somehow during the phase transition. Simple! The angular momentum of the universe-as-a -whole was transferred to the spins of all the individual planets, stars, and galaxies. In fact, the angular momentum of each astronomical entity, according to Carneiro, is proportional to its (mass ...

But the discharge paths followed by lightning strokes often seem unnecessarily tortuous when more direct routes are readily available. The mechanism by which large reservoirs of unlike charges are built up is also obscure. Cosmic rays have now been pro-posed as both a source of charged particles and a provider of low-resistance ionized conduits for lightning to follow. Primary cosmic rays carry considerable energy, most of which appears near the earth's surface in the form of cascades of secondary particles that create complex ionized tracks as they penetrate the dense lower atmosphere. Lightning bolts would tend to follow these precursors along their crooked trails. (Anonymous; "Do Cosmic Rays Trigger Lightning Discharges?" New Scientist, 77:88, 1978.) Comment. Thunderstorm frequency has often been linked to solar activity, and cosmic rays could provide the connection. Could meteorites or "thunderbolts" do likewise?

Science Frontiers ONLINE No. 4: July 1978 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A New Cosmic Heresy Often the simplest of observations will have the most profound consequences. It has long been a cornerstone of modern science, to say nothing of man's cosmic outlook, that the earth attends a modest star that shines in an undistinguished part of a run-of-the-mill galaxy. Life arose spontaneously and man evolved on this miscellaneous clump of matter and now directs his own destiny without outside help. This cosmic model is supported by the Big-Bang and Expanding Universe concepts, which in turn are buttressed by the simple observation that astronomers see redshifts wherever they look. These redshifts are due, of course, to matter flying away from us under the impetus of the Big Bang. But redshifts can also arise from the gravitational attraction of mass. If the earth were at the center of the universe, the attraction of the surrounding mass of stars would also produce redshifts wherever we looked! The argument advanced by George Ellis in this article is more complex than this, but his basic thrust is to put man back into a favored position in the cosmos. His new theory seems quite consistent with our astronomical observations, even though it clashes with the thought that we are godless and making it on our own. (Davies, P.C .W .; "Cosmic Heresy?"

(A "henge" is simply a circular ditch and embankment.) The henge's ditch at Tara is 3 meters wide with a curious series of pits on either side. Its diameter is about 1 kilometer (5 /8 mile) compared to Stonehenge's diminutive 100 meters. Tara had long been considered an Iron Age site, but the presence of the giant henge pushes its use as a ceremonial site back to Neolithic times -- say, to 2,500 B.C .

Two luminous fans opening sunward gave the planet the appearance of a multitailed comet. Maedler made this curious observation on April 7, 1833; and it has come to be known as the Maedler Phenomenon. If it were not for Maedler's fame as an honest, meticulous observer, the event would have been fogotten long ago. A similar observation was made by Gadbury in 1686. The only explanation for the phenomenon offered so far involves some sort of obscure type of halo or sun-pillar effect. (Baum, Richard; "The Maedler Phenomenon," Strolling Astronomer, 27:118, 1978.)

Many mammals, possibly even humans, also possess a homing instinct. But snails? Taxonomically lowly molluscs? But read this letter to the London Times. "For ten days I have tried to banish a large snail which threatens soon-toemerge seedlings. Each day the snail gets lobbed into long grass of a nearby paddock and each night it quits the paddock, crosses a concrete driveway and returns to lurk under its favourite rock. There is no question of mistaken identity because its shell was marked with white paint after the first return trip." (Roberts, M.I .L .; "Snail Tale," London Times, May 21, 1999. Cr. A.C .A . Silk.)

Gulf of St, Lawrence. Aboard the m.v . Appleby , Port Cartier to Immingham. "The aurora borealis was sighted at 0330 UTC. There was a band measuring 35 long in azimuth, with deepblue almost black vertical bands lying between the altitudes of 15 and 25 . The colour changed to brilliant blue at 0335, lasting for about 15 minutes before cloud began to obscure it." What were the "almost black" vertical bands embedded in the main band? Aurora expert R. Livesey replied as follows. "There is a phenomenon called the 'black aurora' which consists of small regions of very low luminosity embedded in brighter auroral light; the 'black' rays reported from the Appleby could have been a phenomenon of this type." (Wilson, J.L .; "Aurora Borealis," Marine Observer, 69:112, 1999.) Black auroras may actually be more than just the contrast effect suggested by Livesey. Low-light TV systems detect clockwise vorticity in the black bands, and the bands seem to be associated with upward electron beams. In other words, black auroras are apparently a distinct phenomeon in their own right and not just nonluminous parts of the visible aurora.
