Accidents. "Left-handed people are almost twice as likely to suffer a serious accident as right-handers, according to a recent study. Stanley Coren, an experimental psychologist at the University of British Columbia in Vancouver, Canada, claims that his finding helps to explain why less than 1 per cent of all 80year-olds are 'southpaws,' whereas they comprise nearly 13 per cent of all people aged 20." Coren surveyed students at his University for four years and found that the probability of a left-hander having a car accident was 85% higher; accidents with tools were 54% higher; home accidents were 49% higher; etc. Coren blames these lopsided statistics upon the fact that the world is ordered for right-handers, not that left-handers are innately more clumsy. (Dayton, Leigh; "The Perils of Living in a Right-Handed World," New Scientist, p. 32, October 28, 1989.) But Coren's study, above, omits the "health" factor, which we now supply from a different source. "Halpern and Coren recently described an association between lefthandedness and a lower life expectancy. This finding is not unexpected because left-handedness has been linked to three leading causes of death in our society - ...

Rather, suggest M. M. Grone and M. Sher, the universe-as-a -whole may undergo a phase change. Such an event has already happened once and it may again. Approximately 10-10 seconds after the Big Bang, the force laws changed discontinuously as the universe cooled. Some models of the cosmos predict that another such phase change may occur when photons suddenly acquire mass. Grone and Sher have sketched the effects on terrestrial civilization: "The most dramatic effect would be the elimination of all static electric and magnetic fields over a range greater than 1 cm, and the elimination of all electromagnetic radiation with frequencies smaller than a few hundred gigahertz. We have shown that there would be relatively little impact on atomic structure and on solar radiation. The absence of electrostatic fields would force a redesign of current power plants (to use smaller solenoids); the absence of radio and television waves would force a much greater use of cables. The elimination of solar and geomagnetic fields would have a significant meteorological impact. The potential ly most devastating effect could be on the propagation of neural impulse along motor neurons; it appears that the effects might be small, but they do depend on the precise value of the photon mass." Crone and Sher conclude that ...

Do you simply starve to death, ending your world's brief experiment with life? Not if a rust-colored substance called tholin is within reach. Tholin may have served as breakfast, lunch, and dinner for the first life on Earth." The tholins are hard, red-brownish substances made of complex organic compounds. They do not exist naturally on earth, because our present oxidizing atmosphere blocks their synthesis. However, tholins can be made in the lab by subjecting mixtures of methane, ammonia, and water vapor to simulated lightning discharges. Conditions like this probably exist many places in the universe. In fact, the icy moons of the outer solarsystem planets appear ideal places for tholin manufacturing. What would eat such stuff? Lab tests show that many kinds of bacteria love it and thrive on it.

It was like a breath of fresh air to read this sentence in Sky and Telescope: "Scientists are still unable to confirm the existence of even a single black hole, despite a widespread belief that such things should, and indeed must, exist." This single sentence won't change anything, because everyone is comfortable with black holes. They are part of the (often false) reality that the media smothers us with. Actually, there are two places where black holes "might" dwell, based upon the anomalous behavior of matter around these regions: (1 ) at the centers of some galaxies, including our own Milky Way; and (2 ) as unseen components of some close double stars, where the mass of the unseen companion is too great for it to be an ordinary neutron star. W. Kundt and D. Fischer, at Bonn University, have recently concluded that the second possibility is better explained without resorting to black holes. For example, a neutron star with a massive accretion disk might suffice. As for black holes at the ...

... Anomalies Under The Rug A series of articles in the science magazine Mercury so slavishly followed the scientific party line on the meaning of the redshift that G. Burbidge was prompted to pen a rejoinder. Burbidge reviewed the considerable observational evidence supporting a non-cosmological interpretation of some redshifts. (Such data has been included in past issues of Science Frontiers and in our Catalog Stars Galaxies, Cosmos.) A typical observation is the apparent physical connection (streams of connecting matter) between quasars and galaxies with radically different redshifts. Burbidge remarks: "Evidence of this kind exists. If it is accepted it means: That at least some quasars do lie at so-called cosmological distances. That at least some parts of the redshifts of quasars are due to some effect other than the expansion of the universe. That quasars are physically related to bright, comparatively nearby galaxies." Burbidge is not concerned by the fact that some astronomers find the data unconvincing, rather he objects to the so-obvious attempts to brush such anomalous data under the rug. His concluding remarks are pertinent to all of science: "I cannot end this part of the discussion without making two points which are rarely made, but which are important: Evidence of the kind just mentioned which is favorable to the cosmological interpretations of the redshifts does not negate the other evidence. It simply means that the world is a complicated place. Only in articles of this kind is one expected to describe such re sults. In articles such as that by Weedman, it is somehow considered all right to totally the noncosmological hypothesis. ...

Gerber, 17 years before Einstein's 1915 paper on the subject, using classical physics and the now accepted assumption that gravity propagates at the speed of light. As for the famous Michelson-Morley experiment, Michelson (an unbeliever in Relativity) believed that he and Morley failed to detect ether drift because the ether was entrained with the earth as it orbited the sun. It is rarely mentioned that Michelson and H.G . Gale repeated the experiment in 1925 to see if ether drift could be detected as the earth rotated on its axis. They did! And Einstein was sorely tried explaining the result. A 1979 repeat of the experiment at the University of Colorado, using la-sers found "unexpected perturbations," which were blamed on "other causes." (After all, Relativity and Einstein are sacrosanct!) The gist of all this is that Hayden and Beckmann suspect that Special Relativity is founded upon quicksand. The reader should not be surprised to learn that Beckmann himself has a theory to supplant Special Relativity once it is discredited.

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. One can also speculate that, if life did develop on Mars, it could have seeded the earth via bits of debris blasted off by meteorite impacts.

We first met Alfven in SF#59,where we commented on his paper "Memoirs of a Dissident Scientist." Alfven is still a dissident, a scientist who has the temerity to claim that cosmic rays have a local rather than galactic origin. Even more heretical is his assertion that electromagnetic forces have shaped the universe rather than the Big Bang! The subject of this entry is not so much Alfven's conflicts with accepted scientific views, but rather whether correct scientific predictions really influence the scientific community's acceptance of theories. This, after all, is what science is all about. It turns out that Alfven has made many correct scientific predictions. (He even shared a Nobel Prize in 1970.) But, as S.G . Brush has related in a detailed article in Eos, being correct is not the same as being accepted.

The concept of directed mutation is counter to prevailing biological dogma, and, naturally, this research bore severe scrutiny. Objections and arguments against directed mutation arose, but the original research was never shown to be faulty. New experiments along this line, by B. Hall at the University of Rochester, have supported the original Harvard work and refuted some of the objections that had been leveled. Working with a special strain of Escherichia coli , Hall starved the bacteria of a certain amino acid, (tryptophan) that they usually got from the environment and could not synthesize. In the days that followed, many of the bacteria mutated so that they could synthesize their own tryptophan. Hall concluded: "Mutations that occur more when they're useful than when they're not: That I can document any day, every day, in the laboratory." Rather than assign any "conscious" goal-seeking attributes to the bacteria, Hall prefers to think that the environmental stress induced a state of "hypermutation." In this state all sorts of mu-tations occurred in abundance. Only those that synthesized tryptophan survived the starvation program; even potentially favorable mutations died quickly. ...

Amphibians and birds do not seem to be so pliable. The worldwide precipitous decline of amphibian populations is alarming. Her-petologists are literally seeing species disappear before their eyes. Here is a typical anecdote: "In 1974, Michael Tyler of the University of Adelaide, Australia, described a newly discovered frog species that broods its young in its stomach. The frog was once so commo 'an agile collector could have picked up 100 in a single night,' Tyler says. By 1980 it had completely disappeared from its habitat (a 100-square-kilometer area in the Conondale Ranges, 100 miles north of Brisbane). It has not been seen since." Similar stories emanate from Brazil, Japan, Mexico, Norway, and elsewhere. Many environmental causes have been proposed, but it is significant that the frogs are also disappearing from nature preserves where environmental pressures are small. D. Wake, a biologist at Berkeley, has remarked: "[ Amphibians] were here when the dinosaurs were here, and [they] survived the age of mammals. If they're checking out now, I think it is significant." In this context, Wake believes that there is a single, global, still-unidentified cause operating. (Barinaga, Marcia; "Where Have All the ...

If the Big Bang is assumed (Who would risk..etc?), this quasar is only about a billion light years from the edge of the universe. Its age, then, is only a billion years. But this stripling of a quasar appears perfectly "normal" with no signs of youth! Its spectrum indicates that even at this young age, the elements were present in the same abundances found in older quasars. And, of course, at this quasar's core there must be a billion-solar-mass black hole (Who would risk..etc.?).

The eye of the predicted storm will be the Ainu, a "racially different" group of some 18,000 people now living on the northern island of Hokkaido. Pure-blooded Ainu are easy to spot: they have lighter skin, more body hair, and higher-bridged noses than most Japanese. Most Japanese tend to look down on the Ainu. Brace has studied the skeletons of about 1,100 Japanese, Ainu, and other Asian ethnic groups and has concluded that the revered samurai of Japan are actually descendants of the Ainu, not of the Yayoi from whom most modern Japanese are descended. In fact, Brace threw more fuel on the fire with: "Dr. Brace said this interpretation also explains why the facial features of the Japanese ruling class are so often unlike those of typical modern Japanese. The Ainu-related samurai achieved such power and prestige in medieval Japan that they intermarried with royality and nobility, passing on Jomon-Ainu blood in the upper classes, while other Japanese were primarily descended from the Yoyoi."

Ordinarily, krypton, being a noble gas, does not enter into any combinations with other atoms - even other krypton atoms. However, P. Lethbridge and T. Stace, at the University of Sussex, have coaxed krypton atoms to cluster together in large, crystal-like clumps with icosohedral symmetry; that is each clump possesses 20 regular faces. The coaxing occurs when gaseous krypton trickles into a vacuum chamber through a hole only 200 micrometers in diameter. The expansion of the gas cools it so that when krypton atmos collide, relative velocities are low, and the weak Van de Waals forces between the atoms are sufficient to hold the clumps together. So far, clumps of 147 and 309 atoms have been detected with a mass spectrograph. One theory of atomic "pack ing" predicts clumps should have "magic numbers" of 13, 55, 147, 309, 561, 923 .. ..

Superimposed on the general X-ray background are discrete X-ray sources separated by extended blobs of X-ray emitting material.

There is, of course, some evidence for the African claim. Studies of genetic material and the fossil record are suggestive, although the latter includes the Middle East as a possible birthplace. Other data, however, put the "founding group" of modern humans in Southeast Asia. The iconoclast here is C.G . Turner, II, an anthropologist at Arizona State University. He has analyzed secondary dental traits (number of roots, bumps, etc.) of 12,000 individuals from around the world - both ancient and modern.

Since then, two large populations, each recognizable by their dental features, have evolved.: (1 ) northeast Asians and the ancient residents of the Americas; and (2 ) southeast Asians, Europeans, ancient Australians, and Africans.

The ethylene warns other trees of impending danger, which then step up their own production of leaf tannin within just five to ten minutes."

Duesberg is back in the news again because his iconoclastic views were prominently featured in a TV documen tary entitled "The AIDS Catch" seen in Britain in June. The scientific community was furious, claiming that the documentary was one-sided and selective. Further, it was maintained that Duesberg's arguments have been completely refuted. Briefly, Duesberg believes that AIDS is not an infectious disease because: Too few T-lymphocytes in the peripheral blood are infected to cause the disease; HIV carriers without symptoms exist; and HIV in pure form doesn't seem to induce Aids in humans or animals. Rather, says Duesberg, AIDS is a collection of symptoms arising from such factors as the repeated use of intravenous drugs and malnutrition.

Adherents of anthropic cosmology hold that our "human-friendly" universe is just one of many universes populating a larger metauniverse. These "other" universes are thought to have different values of the fundamental physical constants (viz., the mass of the proton) and, in consequence, wildly different forms of life. In nonhuman universes, there could even be entities for which our word "life" is inadequate. The second idea is that of an oscillating universe. In this concept, universes expand just so far and then collapse back into the "singularities" (i .e ., black holes) from which they arose.

Physicists have maintained for over a century that the Second Law of Thermodynamics guarantees that our universe with run down one day and that life must cease. This cold reductionist view is seconded by recent evidence that protons, long con sidered immortal, may after all decay. The consequences of proton decay are even more dismal than the dire predictions of thermodynamics: "Perhaps the most disturbing piece of speculation to come out of theoretical physics recently is the prediction that the whole universe is in decay. Not only do living things die, species go extinct, and stars burn out, but the apparently immutable protons in the nucleus of every atom are slowly dissolving. Eventually -- in more than a quadrillion years -- nothing will be left of the universe but a dead mist of electrons, photons, and neutrinos." (Flam, Faye; "Could Protons Be Mortal after All?" Science, 257:1862, 1992.) The death of memory. With increasing entropy and decaying protons on their minds, it comes as no surprise that physicists likewise believe that when one dies, that's it . An afterlife is impossible. How do physicists conclude this? In a letter to the American Journal of Physics, J. Orear proffered an interesting sort of "proof": "One such proof: human memory is stored in the circuitry of the brain and after death ...

Science Frontiers ONLINE No. 89: Sep-Oct 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects In The Dark About Dark Matter During our last two-month collecting cycle, four "dark matter" items worth mentioning turned up. A wider search undoubtedly would have netted many more, because dark matter is worrying a lot of astronomers. Observations of visible matter, the only kind we can see directly, suggest that most of the universe is, in fact, composed of dark matter. This conclusion comes mainly from the belief that something unseen (dark matter) is tugging on visible matter, making it do things the laws of motion say it should not do. All visible bodies, therefore, seem to be careening about in a dense cloud of unseen, unknown masses. These might be dark, Jupiter-sized objects, black holes, and/or some exotic forms of matter. We must choose between the reality of dark matter or admit that something is awry with our laws of gravitation and motion when they are applied on a cosmological scale Now, let us examine those four darkmatter items from the recent literature: D. Lin, a University of California astronomer, has shown that the Large Magellanic Cloud that orbits around our own galaxy (the Milky Way) is being torn apart (" cannibalized") by the powerful gravitational pull of a dense cloud of dark matter surrounding the Milky Way. This dismemberment of the Large Magellanic Cloud cannot be explained by the gravitational forces exerted by the stars in our galaxy ...

Science Frontiers ONLINE No. 89: Sep-Oct 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects An Age Paradox "Cosmologists say the universe may be 8 to 15 billion years old. Stellar astronomers disagree. They say the oldest stars are much older, perhaps 16 to 19 billion years old. Because the oldest stars can't be older than the universe in which they lie, this age paradox presents a thorny problem for astronomers." At least two solutions to the paradox are possible: (1 ) The cosmological distance scale used to determine the age of the universe is incorrect; and/or (2 ) Our theories about how stars work and evolve are in error. Something has to give. (Jayawardhana, Ray; "The Age Paradox," Astronomy, 21:39, June 1993.) Comment. Also pertinent here are H. Arp's collection of red-shift anomalies, which also call into question the cosmological distance scale; and those missing solar neutrinos, which cast doubt on our ideas about how stars work. H. Arp's redshift anomalies are cataloged in AQB and AWB in our catalog: Stars, Galaxies, Cosmos. To order, see: here . From Science Frontiers #89, SEP-OCT 1993 . 1993-2000 William R. Corliss ...

... Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Must we die? the medfly's answer In the early 1800s, B. Gompertz, an actuary, crafted an empirical law stating that mortality rates increase exponentially with age. Later analyses of census records indicated that the situation was not quite as bad as Gompertz had supposed. Nevertheless, the death rate does increase with age; but we might be able to do something about it. Immortality might be achievable -- if we take recent medfly studies seriously. "Growing old does not increase your immediate risk of dying -- at least, if you are a fruit fly. The chances of a Mediterranean fruit fly ( Ceratitis capitata ) dying on a particular day reaches a peak and then declines, according to James Carey of the University of California at Davis and James Vaupel of Duke University, North Carolina, and Odense University in Denmark. Their results contradict the notion that the death rate rises with age in all species." The upshot is that there may be no genetic limit to an individual medfly's lifetime. And, if these results can be extended to humans, "then medical advances might eventually allow the elderly to live indefinitely." (Bradley, David; "Who Wants to Live Forever?" New Scientist, p. 16, November 14, 1992.) From Science Frontiers #86, MAR-APR 1993 . 1993-2000 William R. Corliss ...

... 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. And perhaps math works so well in studying the universe because math, too, must be the way it is in order for anybody to be around to do the calculations. So maybe the existence of communicating creatures requires a correspondence between the physical universe and mathematics. [? ?] " (Siegfried, Tom; Dallas Morning News, p. 7D, January 4, 1993. Cr. L.

(L . Stansass, M. Reingold) First: An Anecdote. Some 30 years ago, D. Berliner, at the University of Utah, was studying human skin. To acquire raw material, he scraped skin cells from the insides of casts discarded by skiiers who had had broken bones. From this debris, Berliner extracted numerous chemical compounds. As far as anyone could tell, these substances were odorless, so he stored them in open flasks. However, Berliner noticed that when people were working in the lab with the flasks, they were more friendly and relaxed than normal. He could not divine the reason until some months later when he decided to cover the flasks of skin-derived substances. Curiously, the lab workers soon reverted to their usual grumpy selves! What could account for this strange behavior change? Knowing that animals often communicated with one another employing chemicals called pheromones, Berliner suspected that the flasks had been releasing odorless human pheromones. Sure enough, analysis of the skin-derived materials proved him correct. Next: A Look Up the Nose. Biologists have long realized that animal noses actually contain two sensory channels. The first is the familiar olfactory system, which humans also possess. The second channel is the vomeronasal system. In animals, each system has its own separate organs, nerves, and bumps in the brain. The function ...

Tifft, an astronomer at the University of Arizona, has maintained for some two decades that the redshifts of the galaxies do not fall on a smooth curve as one would expect. Instead, Tifft asserts, redshifts are bunched at intervals of 72 kilometers/second and at onehalf and one-third that value. Mainstream astronomers insist that redshifts be interpreted as Doppler shifts due to the expanding universe. Quantized redshifts just don't fit into this view of the cosmos, for they imply concentric shells of galaxies expanding away from a central point -- earth! Even though more recent redshift data have supported the notion of quantized redshifts, cosmologists find them undigestible, even pathogenic. But replication and non-replication are the essence of science, so B. Guthrie and W.M . Napier, at the Royal Observatory at Edinburgh, undertook another study. They selected 89 nearby spiral galaxies that had not been incorporated in any of the previous surveys. These galaxies had very accurately measured redshifts and were distributed all over the celestial sphere. "As expected, the galaxies' redshifts showed a smooth distribution. Clearly, no quantization was being introduced by the radio telescopes or the data reduction process. But after Guthrie and Napier corrected each redshift to account for the Earth's motion around the center of the Milky Way -- a different correction for each location in the sky -- out popped ...
