About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

Given the fact that most reviewers are likely to be mainstream and broadly supportive of the existing organization of the scientific enterprise, it would not be surprising if the likelihood of support for truly innovative research was considerably less than that provided by chance.

Cancer cells, always insidious, seem to be able to con its host's body into constructing a special system of capillaries just to support tumor growth. First, the cancer sends out a chemical signal that attracts the host's mast cells. As the mast cells work their ways to the cancer, they apparently leave a heparinlined tunnel for the capillary cells to follow. Before long, the body has provided the blood supply the cancer needs to grow and possibly, eventually kill the host. (Gunby, Phil; "How Do Cancers Attract a Supporting Cast?" American Medical Association, Journal, 245:1994, 1981.) Comment. In view of all of Nature's marvelous adaptations, why hasn't the body evolved a counter strategy to foil cancer sabotage? Reference.

... Venus. 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 Martian atmosphere could be intensified and focussed into an intense beam of infrared radiation of enormous power by placing two large mirrors in orbit, creating a space-borne analog of a laboratory laser. With this huge laser, one could conceive of communicating with neighboring stellar systems. (Taylor, F.W .; "Natural Lasers on Venus and Mars, ...

Science Frontiers ONLINE No. 90: Nov-Dec 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Alien Meteors Meteors or shooting stars are usually considered to be small fragments that have been broken off the asteroids plying orbits between Mars and Jupiter. If this belief is correct, meteors darting into the earth's upper atmosphere would have speeds less than 260,000 kilometers per hour. Any objects with significantly higher velocities must come outside the solar system. It has, therefore, been unsettling to find that quite a few meteors hit our atmosphere at speeds much higher than 260,000 km/hr. Radar measurements of 160,000 meteors by A. Taylor and colleagues, at a New Zealand site, found that about 1% (1500 meteors) struck the atmosphere with velocities greater than 350,000 km/hr. These speedsters must come from beyond the solar system. The question arising is: Whence all this interstellar debris? One hint comes from the fact that the aliens appear to come from the direction in which the sun and its family of planets are traveling through interstellar space. Evidently, this interstellar medium is far from a vacuum; it is strewn with flotsam and jetsam -- but from what smashed planets, moons, and asteroids?

Whalley were driving a Citroen 2CV in heavy rain. Lightning in the distance only. "While the car was four to five metres from the approaching halt sign with the gears still engaged, the engine cut out. The car was brought to a stop at the halt sign and when the puzzled men found that the car would not restart they spent some 10-15 seconds wondering what to do. Then suddenly there was a huge flash, described as an 'explosion', only two metres behind and to their right as lightning went to ground in a triangular, gravelled area which formed part of the road junction system. The inside of the car and the surrounding countryside lit up brightly and, simultaneously, there was a terrific crash of thunder. Startled, the occupants stayed in the car for a minute longer without trying to restart the engine before stepping outside to raise the bonnet of the car. The engine appeared dry and there was no discernible reason for its failure. Then, upon getting back into the car, the engine started at once, since when the vehicle has given no further trouble." Of course this single incident cannot prove that the powerful electrical field preceding a lightning stroke interfered with the car's ignition system. This report is suggestive only.

Mirror Matter is strange "stuff." It interacts with Ordinary Matter only through gravity, it doesn't emit light. It is palpable but invisible. (This sounds weird, but no weirder than quantum mechanics!) Foot also pointed out that stars composed of Ordinary Matter may be orbited by Mirror-Matter planets. Expanding along these lines, whole star systems could be 100% Mirror Matter, and we'd never see them at all. How about Mirror-Matter asteroids and meteors zipping around our solar system -- invisible but palpable and threatening?

At about the same time, the radiolaria were devastated by some sort of disaster. This was also the time when the North American tektite strewn field was deposited -- a field that stretches halfway around the world. John O'Keefe hypothesizes that some of the tektites and microtektites that rained down during this period missed the earth and went into orbit around it, forming an opaque Saturn-like ring. This ring might have lasted a million years or more; and its shadow could have caused the extrasevere winters postulated from botanical data.

... of the spots imply that the average meteor involved weighs 10 kilograms, mostly ice and far larger than has been thought. In fact, they may be characterized as small icy comets; that is, compositionally like the dirty snowballs that comets are now thought to be, but much, much smaller. The implication is that from 1,000 to 10,000 times more material is being added to the earth's atmosphere than previously believed -- most of it being water. (Weisburd, S.; "Atmospheric Footprints of Icy Meteors," Science News, 128:391, 1985.) Comment. From this launchpad, one's thoughts can really take off. How much water can this bombardment of icy meteors add to the earth, Mars, and other solar system bodies? In the item under GEOLOGY about the Greenland ice cores, it was indicated that the extraterrestrial dust influx during the Ice Ages might have been as high as 3 x 107 tons per year. If 10,000 times this amount of water is added to the atmosphere from icy meteors, we are approaching 1012 tons of extraterrestrial water per year -- far from an inconsiderable amount. The effects on the earth's climate could be large. If even greater fluxes of icy meteors were intercepted in the past, one might account for "pluvial episodes" on the planets. And further, comets now seem to transport "primordial organic sludge" around the solar system, as mentioned earlier under ASTRONOMY. We will leave further speculation to the reader.

... They have created volcanoes and massive basalt flows. They have caused mass extinctions. Of course, for two centuries, other catastrophists have proposed similar dire consequences of giant impacts. But Shaw does introduce three ideas that are worth recording here. Large impact craters occur in swaths. Although this has been suggested before, Shaw has mapped out several swaths where large craters of about the same age are located. His "K -T swath" includes the Chicxulub crater (Yucatan), the Manson crater (Iowa), the Avak crater (Alaska), and three more in Russia -- all of which were gouged out about the time of the Cretaceous-Tertiary (K -T ) boundary. Shaw has plotted several other swaths of different ages. The application of chaos theory to solar system debris. Shaw hypothesizes that nonlinear gravitational effects channel asteroids and comets into the inner solar system in intermittent bursts. The bursts are then captured by the earth and other inner planets, with some of these objects grouped in like orbits. Gravitational feedback occurs from earth to orbiting debris. Shaw believes that the uneven distribution of mass inside the earth -- due probably to the impact that created the moon -- influences where asteroids and comets impact. In turn, these large objects keep smashing into the same regions and their cumulative effect contols the flow of material inside the earth. Then, this change in mass distribution feeds back to change orbits and impact swaths. The above is just a taste of what is revealed in Shaw's book of 600+ pages. It cannot fail to ...

... iron, the H-chondrites, they find that the meteorites' ages do not spread evenly through time. Instead, the ages seem to cluster at 7 and 30 million years." Astronomers have hitherto been content to attribute these clumped ages to collisions among the meteorites' parent bodies - the asteroids - which ply periodic orbits. However, S. Perlmutter and R.A . Muller, at Berkeley, point to the apparent 26- to 30-million-year periodicities of three terrestrial phenomena: Biological extinctions in the fossil record, Magnetic field reversals, and Terrestrial-crater ages. Could there be a connection between the clumped meteorite ages and these terrestrial phenomena? Perlmutter and Muller propose that all of these phenomena are the consequence of periodic storms of comets that invade the inner solar system from the direction of the Oort Cloud of comets that purportedly hovers at the fringe of the solar system. These comets not only devastate the earth but also collide with the asteroids, knocking off those bits and pieces we call meteorites. (Anonymous; "Do Meteorite Ages Tell of Comet Storms?" Astronomy, 17:12, January 1989.) Comment. Unanswered above is the question of why comet storms should be periodic. One hypothesis is that Nemesis, the so-called Death Star, a dark companion of our sun, lurks out there, periodically nudging the Oort Cloud of comets, causing it to release some of its comets.

Four frames from a computer simulation of proto-Mercury being stripped of its lighter, outer crust by a collision. Frame times are -1 , + 2.3 , + 7.7 , and + 41.7 minutes after impact. The dark molten sheet of iron in Frame #4 will collapse into a sphere, while the silicates will escape Mercury's gravitational pull. They think Mercury's original, lighter, silicate outer layers were stripped off during the impact of one of the small protoplanets that are thought to have swirled around the inner solar system shortly after its formation. Computations on a supercomputer revealed to these three researchers that, if the protoplanet had hit Mercury at between 20 and 30 kilometers/second, then its dense iron core would have survived pretty much intact. A lower velocity would not have stripped off the lighter outer layers; anything higher would have blasted the whole planet into smithereens. Calculations of this type also suggest that if a protoplanet the size of Mars had hit protoearth, it likewise would have stripped off its light silicate mantle. After this material that had been torn off gravitationally sphericized itself in orbit around the earth, it became--you guessed it - our moon.

Another theory places the bursters in a distant spherical halo about our galaxy. But, in this case, the bursters would have to be much more energetic than astronomers care to contemplate. In fact, if they exist in a galactic halo, we should also be able to detect the bursters in our neighboring galaxies -- but we do not! A more exciting suggestion is that gamma-ray bursters are really very close! This would be consistent with the failure to find cosmological redshifts in the burster spectra. Could they be really close, just a few hundred light away? Perhaps arranged in a spherical halo about our solar system in the vicinity of the postulated Oort Cloud of comets? If this were so, they would not have to be nearly as powerful as they would in the neutronstar model.

The great diversity of the debris swirling around the solar system is making life difficult for scientists trying to reconstruct solar-system history. At the high end of the density spectrum, we now have an asteroid that seems to be mostly metal (probably iron). This is the asteroid Gaspra, some 13 kilometers across, that the Galileo spacecraft encountered in August 1992 on its way to Jupiter. Scientists had not expected Galileo's magnetometer to flicker as it passed Gaspra at a distance of 1600 kilometers -- but it did. In fact, considering the inverse square law and Gaspra's small size, it was a magnetic wallop. Thus, Gaspra is the first known magnetic asteroid; and it is probably mostly metal. (Kerr, Richard A.; "Magnetic Ripple Hints Gaspra Is Metallic," Science, 259: 176, 1993.) At the low end of the density spectrum, we now find that Pluto's moon, Charon, and some of Saturn's moons have very low densities (1 .2 -1 .4 ), meaning they are probably mostly water ice. Such density figures come from direct observation of these objects' volumes combined with mass estimates from their orbital dynamics. (Crosswell, Ken; " ...

Siegfried first reiterates a point made in past issues of SF, namely, that mathematics is a logical system and that we have no right to expect it is correspond structurely with a physical system. In other words, math and nature are fundamentally different entities. Nevertheless, as Barrow stated in a recent interview: "If we were just inventing mathematics from our everyday experience, we would find that it would work really rather well in those areas from which that intuition was gained. But we find almost the opposite...It works most powerfully and persuasively in areas that are farthest removed from the everyday experience that has led to it." Mathematics, for example, leads to verities in quantum mechanics far outside the realm of daily experience. Why is this so? The puzzle deepens when one discovers that there are different kinds of math based upon different forms of logic (as in Euclidian and non-Euclidian geometries). Some brands of mathematics mirror reality better than others. Why? In trying to dispose of these "whys," both matematicians and scientists fall back on the anthropic principle with all its unsatisfying tautological overtones: ". .. the universe is the way it is because that's the way it has to be for anybody to be around to study it.

To understand the answer to the electric fish puzzle, we must restrict the discussion to those fish with active electric sensing systems. This group includes electric eels, South American knife fish, and African elephant snout fish. All of these have evolved, in a remarkable instance of parallel evolution, the capability of generating pulses of electricity. These pulses (up to 1,000 per second) radiate through the surrounding water. Prey and other nearby objects distort these oscillating electric fields. Electroreceptors on the fish and a sophisticated data processing system convert the field distortions into an "image" of the surroundings. M. and S.J . Lannoo, of Ball State University, have watched the black ghost knife fish, which plies murky Amazon waters, approach likely prey tail first. Swimming backward using an elongated belly fin, the knife fish slowly cruises past its potential victim. If the electrical image looks appetizing, the knife fish grabs its dinner with a forward lunge as it appears in front of it.

This is the only way the fish can identify prey because an electric sense cannot be focussed like an eye. But if the fish carried out its scan by swimming forwards, the prey would end up ...

The rings were estimated to be 2-5 kilometers away and 10-30 meters in size. E. Witalis has provided a direct translation of their report. "The light phenomenon, which was strongly luminous, consisted of scintillating, rotating rings arranged as a system of plates (small rings in the centre and increasingly large ones towards the edges). The rings seemed to consist of sparks running around in a circular or slightly elliptical path with an impressive speed. Spontaneously I associated them with electrical discharges. The plate shape was felt as being in some way static as to location, and the sparks moved in a pattern without spreading out at the edges. It seemed that strong force was controlling the event. The sparks looked like having a core and a 'tail' behind. They looked like being able to crackle but no sound was heard, perhaps because of the distance. It was interesting to note that the rings were spinning in opposite directions. The effect clearly illuminated the surrounding air space. The whole light phenomenon took place with knifesharp edges in clear weather (temperature between -1 and -3 deg. C." (Witalis. Erik; "An Air Plasma Whirl, Seen in ...

... data from Japan's new Super-Kamiokande detector suggest that the solar neutrino flux is greater at night than during the day, and that it also varies during the year. (Anonymous; "First Data from New Neutrino Detector," Science News, 151:279, 1997.) Once we learn how to measure neutrinos really well, we can start looking for intelligent signals impressed upon them by advanced extraterrestrial civilizations. W. Simmons and colleagues at the University of Hawaii at Manoa point out that neutrinos are much better than electromagnetic waves for galaxy-wide communication. They are not blocked by dust nor are they smeared out by ionized gas. Any civilization clever enough to colonize the entire galaxy would want to send out neutrino signals if only to keep clocks in far-flung star systems synchronized. Simmons et al calculate that a neutrino detector containing a cubic kilometer of seawater could probably detect neutrino signals from artificial sources located within 3,000 light years of earth. A detector that might be able to do this is being installed in the ocean off the Hawaiian Islands. Naturally, it has an acronym: DUMAND = Deep Underwater Muon and Neutrino Detector.

This feat requires not only the measurement of solar azimuth but also reference to an internal clock. Humans cannot do this without artificial instruments. Furthermore, even on cloudy days, migrating monarchs fly in the proper direction (generally south-southwest). Apparently, they also have evolved a backup navigation system, perhaps a geomagnetic compass. (Perez, Sandra M., et al' "A Sun Compass in Monarch Butterflies," Nature, 387:29, 1997.) Comment.

Can "imaging" work? Obviously, this is a very controversial question. Admittedly, little real scientific research has been done on imaging per se -- it is a bit too radical a concept. But a few scientists are beginning to chart the chemistry and information flow in the mind-body relationship. For example, the death of a spouse has long been associated with the increased mortality of the surviving spouse. Clinical studies of bereaved spouses reveal fewer circulating lymphocytes, which help the body fight disease, and significantly higher levels of cortisol, a substance that suppresses the immune system's response to disease. Although it is very early in the game, there are verifiable correlations between state-of-mind and body chemistry. Further, other researchers have found that there are sympathetic nerve terminals in such organs as the spleen and lymph nodes, both of which play important parts in defending the body. Imaging just might send the right signals through these terminals, while depression might tend to shut the defense system down. (Hammer, Signe; "The Mind as Healer," Science Digest, 92:47, 1984.)

The close-up photos of the asteroid Eros (35-kilometers long) from the spacecraft NEAR-Shoemaker have added two new phenomena to the list of asteroid enigmas. Boulders. Eros is covered with huge boulders -- perhaps a million of them over 8-meters wide. The boulders are likely just accreted solar-system debris; but why are they strewn naked on the surface of Eros instead of being intermixed with other rocky debris? Speculation is that the large boulders were coaxed to the surface preferentially over the eons by seismic vibrations -- said vibrations being caused by multitudinous impacts. This type of jostling action also explains why Brazil nuts greet you when you open a well-travelled can of mixed nuts! Ponds and beaches.

The problem is that aluminum26 is radioactive with a half-life of only about 1 million years -- a very short time astronomically speaking.

Furthermore, archeology is more than shards and arrowheads. Today's physicists enjoy speculating about Theories of Everything, but they really don't nean everything ! They just mean physics and cosmology. Some 5,000 years ago, the Sumerians constructed a remarkable Theory of Everything based upon music, a base-60 number system, and symmetry concepts. These Sumerians didn't have supercomputers but they were able to incorporate into their theory much more than physics and cosmology. Below, E.G . McClain provides some insight into ancient Sumerian thinking: "In ancient Mesopotania,music, mathematics, art, science, religion, and poetic fantasy were fused. Around 3000 B.C ., the Sumerians simultaneously developed cuneiform writing, in which they recorded their pantheon, and a base-60 number system. Their gods were assigned numbers that encoded the primary ratios of music, with the gods' functions corresponding to their numbers in acoustical theory. Thus the Sumerians created an extensive tonal/arithmetical model for the cosmos. In this far-reaching allegory, the physical world is known by analogy, and the gods give divinity not only to natural forces but also to a 'supernatural,' intuitive understanding of mathematical patterns and psychological forces."

The possibility that some terrestrial water might have ar rived from extraterrestrial sources after the earth's formation has been discounted. The major reason behind this neglect was the expectation that the erosive effects of large-scale impacts of water-carrying comets and asteroids would preclude any net accumulation of volatiles, and could even reduce any existing inventories of surface water. C.F . Chyba has recently reexamined this question of cometary water influx vs. impact-caused water losses using the latest estimates of comet/asteroid fluxes during the period between 4.5 and 3.5 billion years ago, when bombardment of the inner solar system was thought to be especially severe. Rather than the expected net loss, Chyba computes that the earth would really have gained more than 0.2 - 0.7 ocean masses in that billion-year period. Venus would have fared equally well, but Mars, more sensitive to impact erosion, would have accreted "only" a layer of water 10-100 meters deep over the whole planet!

Not really. The comets approaching the sun are made visible by sunlight reflected from the gases and dust in the coma and tail, plus some direct emission. However, the heart of the comet, its nucleus, has long been considered a "dirty snowball"; that is, a mixture of dirt and ices. Now it appears that comets are more like "icy dirtballs"!

They have to be because life is conferred by the flow of information. We all learn how the nervous system carries a heavy traffic of electrical signals, but we hear less about chemical signals, and they are more important. Chemical signalling molecules help cells learn what is going on around them so that they can make decisions concerning metabolism, division, and even whether to die not not. This is mainstream biochemistry, although there is much here yet to be learned. A signalling medium that still survives well off the mainstream is the old idea that information is carried from cell to cell via electromagnetic radiation. Yes, we mean mitogenetic radiation--the infamous M-rays of the 1920s and 1930s. During this period about a thousand technical papers were published on mitogenetic radiation -- mostly in Russian.

Although a few other researchers said they detected mitogenetic radiation, most could not replicate Gurwitsch's work.

Weather patterns from North America to Australia lurch ponderously in sympathy. El Ninos occur every 4-7 years, suggesting some periodic phenomenon is waving a geophysical baton. The real cause of El Ninos is still obscure. However, the recent discovery of over 1,000 previously unmapped submarine volcanos rising from the seafloor in the eastern Pacific may lead to El Nino's source. The synchronous eruption of, say, 100 of these volcanos might warm the ocean around Easter Island a tad -- just enough to warm the atmosphere above a bit -- resulting in a shift of the high pressure area. The area of intense volcanic activity covers 55,000 square miles of sea floor where the Pacific and Nazca plates are separating. In addition to the active volcanos, many plumes of 800 F water gush from the sea floor in this area. The volcano-El Nino link is, therefore, not so far-fetched.

The species P. chapmani builds low mounds of pebbles over its burrow systems, and P. hermannsburgensis may use these mounds after they are constructed. The pebbles are of a uniform size and cover a large area, often a meter in diameter. The pebbles are probably collected both by excavation and from the surface. Some local mammalogists believe these are used as dew traps. Since the air around the pebbles warms more rapidly as the sun rises than do the pebbles themselves, dew forms on the pebbles by condensation. As the areas in which these mounds are found are quite dry, except after a heavy rain, these dew traps solve the problem of water shortage. Local farmers use the many pebble mounds for mixing concrete. It is believed that the ancient people of the Mediterranean region used a dew trap method comparable to that of P. chapmani ."

On the surface, left-handers seem little different from right-handers. So why the highly skewed population? Why not 50% of each? Dr. Peter Irwin, at Sanddoz, Ltd., of Basle, Switzerland, has what is certain to be a controversial answer. He was led to his conclusion by a series of experiments with psychoactive drugs, performed in collaboration with Professor Max Fink, SUNY, Stony Brook. Left-handers, the study demonstrated, are much more sensitive to drugs that act upon the central nervous system. Irwin believes that this finding is consistent with the known association of left-handedness with epilepsy and learning disorders. "But perhaps the most exciting aspect of Irwin's hypothesis is that it makes evolutionary sense. 'A greater resistance of right-handers to centrally active substances, when Man was a forager and before he learned to identify non-toxic edibles, would have favoured righthanded survival. This might account for the skew in the present handedness distribution that is unique to humans.'" And why should left-handers be more sensitive to psychoactive substances?

At the same time, 1983 proved to be a bumper summer for the production of 'mystery spirals' (and for heat whirlwinds generally). Moreover, and entirely unexpectedly, some of the spiral formations turned out to be symmetrically complex systems in an extraordinary manner: as many as four sets in different parts of southern England were found to consist of a single circle attended by four smaller satellite ones. "The beauty of these sets of circles caught the attention of the national newspapers, and thence the imagination of the general public. The story about the manner and the sequence of several of the 1983 discoveries has been given by Ian Mrzyglod (Probe Report, vol. 4, 4-11). Here, we shall simply summarize the main facts, many of which have not been detailed before. "Set 1. Set of five circles at Bratton, Wiltshire (NGR ST 902522, below and northeast of the Westbury White Horse), consisting of one large circle (15 m diameter) and four satellites (each 4 m diameter). The distance between opposite pairs of circles was about 40 m (centre to centre)." The other three sets are very similar and ...

How fortunate it is that kangaroo pouches open at the top; otherwise, little kangaroos would be falling out all over the place. While some marsupials have pouches opening "up" or "forward" in quite a few others evolution got the directions for pouch manufacture reversed. The koala, the wombat, the thylacine, and the marsupial mole all have backward-opening pouches. Obviously, a forward-opening pouch on the mole would act like a dirt scoop, to the great inconvenience of any occupants. On the other quadrupeds, the backwardopening pouch may protect the young from branches and vegetation. (Marshall, Jeremy H.; "Directional Pouches," Nature, 309:300, 1984.) Comment. This is an example of the socalled Problem of Perfection, where life seems marvelously attuned to its environment; that is, "fittest." Somewhere among the millions of species alive today, there must be one out-and-out failure. Of course, if full-scale nuclear war breaks out, we will know that evolution did make at least one mistake!

The babirusa's stomach possesses an extra sac; and the animal often browses on leaves and shoots. It does not, however, chew a cud. The Indonesian babirusa, a pig-like animal with curious tusks and an unusual digestive system (for a pig). Taxonomists are a bit puzzled over the babirusa. They aren't sure whether its closest relatives are modern pigs, peccaries, or hippos. The babirusa's "tusks" pose more questions about its evolution: "The creature's oddest characteristic is the two impressive pairs of curving tusks grown by the males. One pair are simply extended lower canines, but the second are actually upper canines, the sockets of which have rotated, resulting in tusks that grow through the top of the muzzle and emerge from the middle of the animals's face. The effect is bizarre and startling. The males fight with their dagger-like lower canines and probably deflect opponents' blows with the upper set, thus protecting their eyes. Indonesians say the tusks are similar to deer antlers, giving the babirusa its name, which means 'pig deer.'" (Rice, Ellen K.; "The Babirusa: A Most Unusual ...

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. The computer-generated display shown below lays out a huge square spiral, with each prime a bright dot. ...
