While Venus does trap solar radiation in its atmosphere greenhouse fashion, data from Pioneer Venus Orbiter show that the planet radiates 15% more energy than it receives from the sun. In other words, Venus's surface is hotter then it would be if only the greenhouse effect were operating. Where could this extra energy come from? If it arises from the decay of naturally occurring radioactivity, Venus would have to have 10,000 times as much radioactivity as the earth. If this is the case, Venus must have had an origin radically different from the earth's . (Anonymous; "The Mystery of Venus's Internal Heat," New Scientist, 88:437, 1980.) Comment.

Cairns performed experiments with bacteria that implied that said bacteria could "direct" their own mutations so that they could cope more speedily with sudden environmental trauma. (SF#64) In Cairns' experiments, bacteria unable to digest lactose were presented with an all-lactose diet. They quickly acquired the mutations needed to digest the only food available. They did not have to wait for random mutations to accidentally hit upon the correct genome changes. A firestorm spread across the scientific community, even though other researchers saw similar effects. It was traumatic! One of science's foundation stones was at risk. The current theory of biological evolution insists that all mutations are random. Cairns believed he had shown that his bacteria experienced only useful mutations. This claim was too awful to accept. In the July 21, 1994, issue of Science, two new papers appeared that, while not proving that only useful mutations occur in Cairns-type experiments, do indicate that something unusual is indeed happening. Basically, when bacteria are under stress (say, starving), a "distinctive" type of mutation occurs! Is "distinctive" a code word for "non-random"? The title of the commentary accompanying the two articles says it all. (Culotta, Elizabeth; "A Boost for 'Adaptive' Mutation," Science, 265:318, 1994. ...

Such observations are anomalous becaouse the only wellexplained elliptical halo is formed when the lower and upper tangential arcs of a 22 halo join together. Possibly because of the absence of appropriate theory, R. White, in 1981, suggested that the observations recorded in GEH2 were only the consequences of observational error or inaccuracy in representation of the phenomenon. (This assertion is well-known to all anomalists!) Recently, however, several elliptical halos have graced the skies of Finland. We provide below a summary of these observations, as prepared by J. Hakuma ki and M. Pekkola. First, though, we express appreciation to Hakumaki and Pekkola for a paragraph headlined SOURCEBOOK PROJECT ANOMALIES, where in effect they vindicate the approach of the Project. We now quote from the summary of their article. "In December 1987 two Finnish amateur astronomers observed and photographed a peculiar vertically elliptical ring surrounding the moon. A literature study carried out soon after this first observation brought to light ten reported historical cases of this type of rare halo phenomenon. It was found out that the existence of these elliptical halos has been uncertain to date due to a lack of photographic evidence. One indication of this is that none of the major modern works on halos mentions such phenomena. During 1988 three more elliptical halos were seen by the Finnish halo observing network. Observations and photographs taken of these phenomena seem to indicate that at least two types of elliptical halo exist. The smaller one was first reported by US astronomer ...

Emerson had his Yagi antenna pointed in the direction of the phenomenon. His receiver was tuned to 145.8 MHz. The sun is always emitting radio noise, and one would expect that the moon passing in front of the sun would gradually cut off most, but not all, of the radio noise picked up by the antenna and, after the eclipse's midpoint, the noise would increase back to normal levels. Instead of the expected: Radio noise power measured during a partial solar eclipse. The arrows indicate the stages of the eclipse "There was no radio evidence of any effect of the solar eclipse until 1822 UTC, 58 minutes after the start of the eclipse. At that point, all detectable solar emission disappeared within the space of about nine minutes. The emission did not start to reappear until 72 minutes later, at 1943 UTC, and was fully restored by 1951 UTC, 13 minutes before the end of the eclipse, which occurred at 2004 UTC. "The fact that radio emission disappeared and reappeared fairly abruptly part way through the eclipse indicates that most of the radio emission was occurring from one discrete point on the sun's surface rather than from the entire solar disc."

Navy began operating a 90-kilometer-long radio antenna stretching pole-to-pole through a Michigan forest. Broadcasting at only 76 hertz, this long antenna can communicate effectively with submerged submarines. Although the antenna produces electromagnetic fields about the same as those from a large household appliance, some of the trees adjacent to the antenna have enjoyed an unexpected spurt in growth, according to D. Reed and G. Mroz of the Michigan Technological University. "The researchers have been gathering data on the growth of trees since 1985, making measurements at two sites, one near the antenna and the other 50 kilometers away. The results seem to suggest that the electromagnetic field has a subtle influence on the forest. They found that two species of trees, northern red oak and paper birch, do not seem to be influenced by the antenna at all. But red pines near the antenna grew taller than red pines at the distant site, while aspen and red maple grew thicker than their counterparts further off." (Kiernan, Vincent; "Forest Grows Tall on Radio Waves," New Scientist, p. 5, January 14, 1995) Trees are not the only plants affected.

Bellingham and M.L .A . MacVicar, at MIT, discovered a remarkable effect: "One interesting and surprising property of electrochemical cells was discovered by accident. Normally, the magnetometer scans each cell as the cell moves horizontally beneath the magnetometer. During one run, the researchers left the cell in a single position for a long time while the magnetometer was still on. After 20 minutes or so, the magnetic field strength began to drop. 'It was very dramatic to watch this field collapse,' says MacVicar. After about a minute at zero, the magnetic field grew larger again but in the opposite direction." These reversals occurred over and over again at regular intervals. (Peterson, I.; "Tracing Corrosion's Magnetic Field," Science News, 130:132, 1986.) Comment. The self-reversal of magnetic specimens has been observed before under some conditions, but here is a periodic reversal of an electrochemical system. Why place it under the heading of Geology? Because the earth's field seems to reverse on a fairly regular basis. Catastrophists have invoked as teroid or cometary collions to account for these flip-flops, but it might be that the earth contains giant electrochemical cells that spontaneously reverse on a million-year timescale rather than minutes.

The big puzzle is: How could the Aztecs have done it without modern lapidary tools -- the skull is so smooth and perfect? Well, maybe the Aztecs didn't carve it! A. Rankin, of Kingston University, has examined the tiny trails made by fluid inclusions in the quartz matrix. He finds that they are characteristic of Brazilian quartz. In fact, there seem to be no suitable sources of massive quartz crystals anywhere in Mexico; and the Aztecs do not appear to have made any incursions into Brazil. Even worse, British Museum experts have now found small cuts made by steel tools on the insides of the teeth. ...

By properly positioning a mirror, an arm amputee can see the image of his flesh-and-blood limb appearing where his lost limb would normally be -- in a sense visually resurrecting the lost limb. In this way, scientists can explore the effects of vision upon the multitude of very strange "phantom-limb" phenomena reported by amputees. V.S . Ramachandran et al have described some of their findings in Nature. "Nine arm amputees were studied. A tall mirror was placed vertically on the table, perpendicular to the patient's chest, so that he could see the mirror reflection of his normal hand 'superimposed' on the phantom. In the first seven patients, when the normal hand was moved so that the phantom was visually perceived to move in the mirror, it was also 'felt' to move; that is, a vivid kinaesthetic sensation emerged. (These sensations could not be evoked with the eyes closed.) In patient D.S ., kinaesthetic sensations were evoked even though he had not experienced movements in the phantom for the preceding 10 years."

"At 1800 UTC on a clear moonless night while 150 n.mile east of the Somalian coast a whitish glow was observed on the horizon and, after 15 minutes of steaming, the ship was completely surrounded by a sea of milky-white colour with a fairly uniform luminescence. The bioluminescence appeared to cover the entire sea area, from horizon to horizon but above the surface, and it appeared as though the ship was sailing over a field of snow or gliding over the clouds.

They live in underground colonies with a social structure like that of ants and termites. There are castes of workers, and only the queen, an oversized female, breeds. Naked mole rats are also intensely xenophobic; they avoid or fight with other mole-rat colonies. But such tightly closed societies lead to inbreeding with all its deleterious effects. For naked mole rats to survive over the long term, a biological solution to the inbreeding problem had to be found. The response of the species to this threat is the occasional production of a "dispersive morph." The largest and most successful colonies produce -- somehow -- a larger-than-normal individual, almost always a male, that is fuelled with extra fat and possesses a yen to travel. He is disinclined to mate with the resident queen, preferring to leave the colony for amorous adventure elsewhere. Thus, intercolony gene flow is established.

But cancer is more insidious than expected. A precancerous founder cell may actually subvert nearby noncancerous cells and turn them into cancerous cells. In this sense, the first precancerous cell recruits and transforms healthy cells, enlisting them in its destructive operations, and thereby turning them against the body that produced them. No one yet knows how this subversion is effected or how it evolved. (Why is there cancer anyway?) The basis for this claim involves a few rare human mosaics, whose bodies are built of cells with two different genetic complements. Cancers in human mosaics have been found to contain both types of cells and, therefore, did not grow from a single cell alone.

Surrounding this is a fluid outer core, which in turn is wrapped onionlike by the mantle and outer crust. Earthquakes are always sending seismic waves through these regions and jostling seismometers installed all over the globe. From this wealth of seismic signals, geophysicists have found that the inner core, lubricated by the fluid outer core, rotates about 1.1 per year faster than the mantle and crust. The inner core interacts with the geomagnetic field and is, in effect, like the rotor of a slow, ponderous induction motor. Expanding upon this vision of the earth as a colossal electrical machine, E. Stokstad writes: "Electric currents of about a billion amps flow across the boundary between the solid inner core and the fluid outer core that lies around it. In the presence of the Earth's magnetic field, these currents generate massive forces that tug on the inner core. And because the outer core has a relatively low viscosity, the inner core can spin freely." (Stokstad, Erik; "Earth's Heart Is in a Spin," New Scientist, p. 18, July 20, 1996.

But the mysterious moving rocks on Racetrack Playa in Death Valley have lured them out of their ivied halls. We quote from the abstract of a report seen in the mainstream journal Geology . "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. Their maps revealed many "mated pairs" of rocks, whose curving tracks matched near their origins to within a few centimeters, even though the tracks were separated by up to 830 meters (over 0.5 mile!).

In the view of many astronomers, including T. Van Flandern, there resides the debris of an exploded planet. Van Flandern has adduced considerable evidence supporting the exploded planet hypothesis, which we will pass over in favor of a look at the possible effects of said exploding planet upon a large but equally hypothetical satellite of said planet. Such a satellite would have been heavily pelted by debris on the side facing the exploding planet. Furthermore, this battered sphere, having lost its gravitational "anchor," would assume a new orbit around the sun as well as a new orientation in space.

What possible connection could there be between this purported cataclysm and the "face on Mars"? The connecting thread is very weak but so beguiling that we must mention it. T.

These mammals are effectively toothless for predatory purposes. In fact, some marine biologists speculate that they secure their slippery prey by suddenly vacuuming them up by actuating a pumplike tongue. (AR#2 ) But how do the beaked whales find their prey in the first place? With their sonar, of course. But these superbly streamlined animals lack the huge external ears of the sonar-using bats. How do they detect the weak echoes bouncing off fleeing fish? P. Zioupos and J.

It contains 35 per cent calcium by weight -- 13 per cent more than the highest value known previously.

Crater ejecta rich in extraterrestrial material would be blasted to an altitude of 10 km, where winds would insure global distribution. In terms of biological stress, the 10-km projectile would transfer 40-50% of its kinetic energy to the atmosphere, creating a heat pulse that could raise global temperatures 30 C (50 F) for several days. Many large animals might well succumb to such a temperature transient. In addition, the protective ozone layer might be blown away by shock waves and not reform for a decade.

R.A . Millikan's oil-drop experiments, circa 1911, demonstrated conclusively that the basic, indivisible unit of electrical charge was that on the electron. Later, an exception was made for those quarks that are firmly locked up inside nuclear particles. They each have 1/3 the electron's charge -- but they never, never escape to the outside world. It was, therefore, counterintuitive when R. Laughlin proposed in 1982 that fractional electrical charges actually could show up elsewhere in physics. The phenomenon that suggests this possibility is the Fractional Quantum Hall (FQH) effect. Physicists reluctantly accepted the likelihood of fractional charges in this well-verified phenomenon; but the experiments demonstrating fractional charge were a bit esoteric -- the fractional charges were not "palpable" enough. Two new experiments have made fractional charges much more tangible. When a layer of electrons, held just above absolute zero, is subjected to a powerful magnetic field, you can almost "hear" the fractional charges. The signals from these experiments have been likened to hail hitting a tin roof. Just as you can gauge the size of hailstones from their impact, so you can estimate the electrical charges involved in these experiments -- they are 1/3 that of the electron.

Both events also purport to explain long-standing puzzles. Scenario #1 . The Bosporus silt plug blows. During the last Ice Age, sea levels dropped hundreds of feet exposing the continental shelves. The planet's great rivers cascaded over the edges in great waterfalls. The rocky sill at Gibraltar kept the Atlantic waters out of the Mediterranean, and this sea began to dry up. Farther to the east, the Black Sea was now cut off from the Mediterranean's salty water by the silt-choked Bosporus, that narrow strait separating Asia Minor from Europe. In consequence, the Black Sea became a vast fresh-water lake fed by Europe's rivers to the north. The Ice Age eventually waned, and the oceans and Mediterranean began to rise. About 7,000 years ago, the hydraulic pressure on the Bosporus silt plug became too great and it popped. Salty Mediterranean water poured into lowlands around the Black Sea. Scientists estimate that 50 cubic kilometers of water surged through the Bosporus each -- 200 Niagaras in one colossal waterfall.

Tifft and Cocke begin their article with this sentence. Wisely, they followed with the tale of how vehemently the quantization of the atom was resisted earlier in this century. They were wise because without such a reminder to be open-minded, many astronomers would automatically toss their article in the wastebasket! In fact, when Tifft's first paper on redshift quantization appeared in the Astrophysical Journal, the Editor felt constrained to add a note to the effect that the referees: "Neither could find obvious errors with the analysis nor felt that they could enthusiastically endorse publication." Even today, after much more evidence for redshift quantization has accumulated, scientific resistance to the idea is extreme. We shall now see what all this fuss is about. Tifft first became suspicious that the redshifts of galaxies might be quantized; that is, take on discrete values; when he found that galaxies in the same clusters possessed redshifts that were related to the shapes of the galaxies. The obvious inference was that the redshifts were at least partly dependent upon the galaxy itself rather than entirely upon the galaxy's speed of recession (or distance) from the earth. Then, he found more suggestions of quantization. The redshifts of pairs of galaxies differed by quantized amounts (see figure). More evidence exists for galactic quantization, but ...

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. Deming and Mumma speculate that the natural laser action existing in the ...

The usual effect of a parasite upon its host is debilitation, often to the point of death. But parasites have to reproduce, and some settle for the modification of their hosts in ways that improve their chances. Parasites can change the size, color, and even the behavior of their host. The object is usually to encourage a specific predator to eat the host so the parasite can continue its life cycle. A classic example is the lan-cet fluke which infests ants and then sheep. The problem is that sheep don't normally eat ants, giving the flukes a chance to switch vehicles. So, the innovative flukes somehow force the ants to crawl to the tops of plants and lock themselves there with their jaws. The next hungry sheep that comes along has his meal seasoned with ants. The bulk of the present article deals with thorny-headed worms, which are not as endearing as the lancet flukes. These parasites are merely bags of reproductive organs attached to a thorny probiscus, by which they attach themselves to the intestinal walls of vertebrates. Living in a sea of processed nutrients, the worms don't even have a digestive tract. Part of the life cycle of this parasite is spent in arthropods (insects, crustaceans).

With a fluid core, the earth developed a strong magnetic field (much stronger than those of the other inner planets) through dynamo action. This field protected nascent life from space radiation -- and here we are! (Hecht, Jeff; "Lunar Link with Life on Planets," New Scientist, p. 40, January 21, 1988.) Comment.

Morphologically, these waves resemble noctilucent clouds, which are sun-illumined, high-altitude clouds. The infrared waves, however, appear when the sun is well below the horizon. Since these waves are seen only at low angles over the horizon, some geophysicists propose they are the result of a geometric effect produced by viewing a rippled layer of weakly emitting gases in the upper atmosphere. When one looks at this rippled layer just above the horizon, one sees alternating thick and thin sections due to the perspective. The thick portions will appear brighter than the thin sections. As for the origin of this postulated rippled layer; no one is sure. Gravity waves may be involved. (Herse, M.; "Waves in the OH Emissive Layer," Science, 225:172, 1984.) Comment.

Maddox begins by mentioning the 20-plus-year collection compiled by Professor G.W . Brown, University of London, of life-events that affect the health of outwardly normal people.

The double star DI Herculis has a Newtonian precession rate of 1.93 degrees per century, with another 2.34 added by relativistic effects. With more than 3,000 well-observed orbits of this star system on the books, astronomers come up with only 0.64 degree per century, instead of the 4.27 predicted by theory. Something is obviously awry; and all searches for errors and other influences on the orbit have been negative. (Anonymous; "Double-Star System Defies Relativity," New Scientist, p. 23, August 29, 1985.) Comment. As a matter of record, Newtonian mechanics can account for Mercury's perihelion advance if the sun is actually an oblate spheroid instead of the mathematically perfect sphere usually assumed. Also, the gravitational theory of J. Moffat seems to explain the motions of both Mercury and DI Herculis. From Science Frontiers #42, NOV-DEC 1985 . 1985-2000 William R. Corliss ...

... Science Frontiers ONLINE No. 57: May-Jun 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A NEARBY RING OF COMETS?Some 589 long-period comets are known. They ply orbits around the sun that may take millions of years to complete. Astronomers are generally agreed that these bodies originate in a very distant (100,000 A.U .* ) halo of cometary material surrounding the entire solar system. J. Oort proposed this cloud, and it is named after him. Of course, we anomalists become wary when scientists "generally agree" on a hypothetical entity that no one can see. 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. Like the Oort Cloud, the Kuiper Cloud has not been seen yet, but we just might be able to with today's equipment! Its existence is hypothesized from the parameters of a different group of comets -- the so-called "short-period" comets, as exemplified by 76-year Halley's Comet. About 120 short-period comets have been discerned so far; and our computers now tell us that they cannot have originated in the Oort Cloud. Something closer and concentrated ...

... Issues This Issue Sourcebook Project Sourcebook Subjects Megawalls Across The Cosmos "The universe is crossed by at least 13 vast 'walls' of galaxies, separated by about 420 million light years, according to a team of British and American researchers. The walls seem to be spaced in a very regular way that current theories of the origin of the universe cannot explain." "Walls" of galaxies emerge when galaxy separation distance is plotted against the number of galaxies possessing specific separation distances. (128 million parsecs = 420 million light years). The astronomers have collected observations of galaxy redshifts along a linear "borehole" through the universe 7 billion light years long centered on the earth. If the redshifts are assumed to be measures of distance (as mainstream thinking demands), one gets the clumping effect seen in the accompanying illustration. (Henbest, Nigel; "Galaxies Form 'Megawalls' across Space," New Scientist, p. 37, March 19, 1990.) Comment. Not mentioned in the above article are the papers by W.G . Tifft on quantized redshifts. (See SF#50, for example.) It will be interesting to learn if "boreholes" pointed in other directions will encounter the same megawalls. If they do, the earth will be enclosed by shells of galaxies, much as some elliptical galaxies are surrounded by shells of stars. Wouldn't it be hilarious if the earth were at the center of these concentric shells? Some measurements of the universe's rotation also seem to imply geocentrism! It is more likely, however ...

... Issues This Issue Sourcebook Project Sourcebook Subjects Of Dust Clouds And Ice Ages Ice cores from the polar ice at Camp Century, in Greenland, have been analyzed for the presence of cosmic dust. "It is concluded that on five occasions during the interval 20,000-14,000 years BP, cosmic dust mass concentrations in the solar system rose by one and two orders of magnitude above present day levels. Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate. Thus it is quite possible that these dust congestion episodes were responsible for the abrupt climatic variations which occurred toward the end of the last Ice Age." Whence these interplanetary dust clouds? The author of this article ruled out terrestrial volcanism (an insufficient source of iridium) and encounters with asteroids and cometary tails (too infrequent to account for the long periods of high dust levels). Rather, the dust source may have been the same event that created the recently discovered dust ring between Mars and Jupiter, which is believed to be only a few tens of thousands of years old. The nature of the "event" is not specified. (LaViolette, Paul A.; "Evidence of High Cosmic Dust Concentrations in Late Pleistocene Polar Ice ( ...

... Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Interplanetary Doldrums A special session of the 1999 Fall Meeting of the American Geophysical Union was convened to discuss an extraordinary event: "The day of the solar wind almost disappeared." That was May 11, 1999. The doldrums lasted over 27 hours. Actually, the velocities of the particles constituting the solar wind did not slacken much: 360 kilometers/second, down just 10% from the norm. The wind's density, though dropped from 10 to 0.2 particles/cubic centimeter. Nothing untoward happened on the earth's surface. In space, the earth's magnetosphere expanded when the pressure of the solar wind diminished and more X-rays were emitted from the polar atmosphere, but these effects did not surprise anyone. The big question is: What happened on the sun that stopped its exhalations? No one seems to have an answer. (Lazarus, Alan J.; "The Day the Solar Wind Almost Disappeared," Science, 287: 2172, 2000.)
