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 ...

Newspapers and TV news programs all over the country described these unidentified explosions. However, not a word about the detonations appeared in most of the scientific publications we regularly monitor, with the exception of the British New Scientist and a recent article in Science, 199:1416, March 31, 1978. Comment. The detonations were rather strong, shaking houses and even causing picture windows to fall out. In some instances, flashes of light and other luminous phenomena were reported. The sounds were characterized as "air quakes" by some scientists because they did not always register on seismographs, although they were usually recorded on air-pressure monitoring equipment. One's first inclination is to attribute such detonations to supersonic aircraft and missles, but the U.S . military immediately denied they were to blame. Seismic noises come to mind next, but the frequent failure to register the events on seismographs suggested an atmospheric phenomenon. The National Enquirer (January 24, 1978) rather predictably linked the booms to UFOs. In the federal government, the Naval Research Laboratory (NRL) was assigned the task of tracking down the booms. In March, NRL reported that all of the 183 detonations they investigated were due to supersonic aircraft. That seemed to end the matter -- just as the ...

Protoavis, from the late Triassic, appears at the time of the earliest dinosaurs, and if the identification is upheld it seems likely that it will be used to argue against the view of John Ostrom of Yale University that birds are descended from the dinosaurs. It also tends to confirm what many paleontologists have long suspected, that Archaeopteryx is not on the direct line to modern birds.

Apparently the yogis of ancient India were the first to notice that breathing is dominated by either the right or left nostril for short cycle spans of one to three hours. (Cycles of this duration are known as ultradian rhythms, and are common to many biological functions.) By simply placing a mirror under your nostrils and watching for the larger amount of condensation, one can determine which nostril is in use. "What are the ramifications of this seemingly insignificant phenomenon? The yogis reportedly have said that improved sleeping, more satisfying sex, enhanced digestion, and appropriate thought patterns were controlled by the use of a certain nostril." It is further maintained that one can force a change in nostril breathing through meditation. In this way, it is possible to enhance sleeping, sex, digestion, and mental acuity!

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?"

Those who claim psychic powers state that earth energies (whatever they are) seem to focus at these ancient constructions. The story goes that the builders of the stone circles could also detect these natural forces and intentionally chose these spots where the energies were most powerful. "Proper" siting and orientation were doubtless important to the builders of the megalithic structures, but can modern, no-nonsense science even begin to explore these mystical, psychic claims? Given today's scientific impatience with all psychic subjects, one would not expect a scientific journal, even a popular one, to touch the subject of "earth energies." Yet, here is an article describing the use of ultrasound detectors and Geiger counters in surveying megalithic monuments for foci of earth energies. Sure enough, curious enhancements of ultrasound intensity were discovered at the Rollright Stones. At another site, the natural radiation background level was anomalously depressed.

(Other supernovas have been much too far away.) The prime suspect was the star Sanduleak -69 202. But then it was claimed that old -69 202 was still alive and well. This presented a quandry because no other star in the area was large enough to go supernova. But now it seems there was a mistake, and it was Sanduleak -69 202 all along that detonated. (Waldrop, M.

Why the sudden surge of "civilized" activities: drama, poetry, philosophy, mathematics, and even science? It was all because the Ancient Greeks developed an alphabet that included vowels in addition to the consonants. The Greek language became a full phonetic representation of language. The left side of our brain, it seems, is much more capable than the right in matters phonetic. In contrast, other forms of writing in the ancient world, such as hieroglyphics and vowelless alphabets, are better handled by the right side of the brain. (As an aside, it is interesting that, in the modern world, Japanese and Chinese are better processed by the right side of the brain, while the phonetic representations of language, such as English, are handled better sinistrally.) Back in Ancient Greece, the new alphabet shifted language activities to the left side of the brain. According to J.R . Skoyles, this "unlocked" left-brain competences that had previously been analogous right-brain competences. The newly liberated competences involved rational, analytical, and logical faculties. Thus from the addition of a few vowels sprang Ancient Greece and, in time, modern civilization.

While volcanic eruptions form most sea-mounts, these mountains consist of a nonvolcanic rock called serpentinite, and oceanographers are not entirely sure how the serpentinite mountains formed." The theory of plate tectonics has the Pacific plate diving under the Philippine plate along the Mariana trench. It may be that water trapped in the downgoing crust leaks out, rises, and serpentinizes the crust above. This altered rock, being lighter than that surrounding it, may slowly rise through it, eventually forming undersea mountains. (Monastersky, Richard; "Novel Mountains and Chimneys in the Sea," Science News, 134:333, 1988.) Comment. This all sounds pretty speculative, but those mountains had to come from somewhere. Perhaps the serpentinite mountains are just one manifestation of a larger phenomenon: the chaotic slithering and popping up and down of crustal material.

This is one reason why cold fusion got the cold shoulder from most physicists. Now for the "however" that is the hallmark of Science Frontiers : "Thirty years ago, Otto Reifenschweiler was searching for a compound which could protect Geiger-Mueller tubes from damage when they are first ionised. He found the compound, which became a money-spinner for Philips, in a mixture of titanium and radioactive tritium. He also discovered that as the mixture was heated, its radioactivity declined sharply. No process known to physics could account for such a baffling phenomenon: radioactivity should be unaffected by heat. Nevertheless, as the temperature increased from 115 C to 160 C, the emission of beta particles fell by 28%." Reifenschweiler and his colleague, H. Casimir, put this discovery on the backburner and concentrated on the Geiger-Mueller tubes. The recent furor over cold fusion impelled them to resurrect the work and publish it in the January 3 issue of Physics Letters A . Is there a new phenomenon here? Is it relevant to cold fusion?

It was all pretty obvious; how could such complex, specialized animals have evolved twice? But in Science Frontiers, there is ever the "however": "Arnd Schreiber, Doris Erker and Klausdieter Bauer of the University of Heidelberg have looked at the proteins in the blood serum of megabats and primates and found enough in common to suggest a close taxonomic relationship between the two groups. (Biological Journal of the Linnean Society, 51:359)" An explanation might be that the similarities between the microbats and megabats represent adaptations to similar environmental niches rather than a common ancestry.

Science Frontiers ONLINE No. 15: Spring 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Evolutionary Struggle Within Ted Steele, an immunologist, has come up with experimental evidence showing in some cases that acquired immunity may be transmitted to progeny. When Steele's research was announced, many scientists and science writers rushed to the defense of Darwinism. They pointed out with unseeming vigor that a revival of dread Lamarckism or the Inheritance of Acquired Characters was not indicated. It is true that Steele has proposed a Darwinian interpretation of his findings, but his theory adds a startling new dimension to the development of life. In essence, Steele asserts that an organism's immunological system is really the evolutionary scenario in miniature and compressed in time. The body's immuno-logical system is trying to cope with up to 10 million defensive cells. The only defensive cells that survive and multiply are those that happen to encounter an invader that they can lock onto and destroy. The "fittest" defensive cells are those that have just the right characteristics to knock off invaders, and only they survive permanently in the body's defensive arsenal, giving it acquired immunity. The Lamarckian part of this story occurs when the RNA of the selected defensive cells gets passed on to the organism's progeny. (Tudge, Colin; "Lamarck Lives -- In the Immune System," New Scientist, 89:483, 1981.) Comment. The picture evolving here is one of a hierarchy of evolutionary struggles -- say, ...

Soon, this blemish spread into an oval 21,000 kilometers in length. By early November, it had developed into a planet-encircling band. Apparently, Saturn had "burped," expelling hot gases from its interior. [Saturn emits 50% more heat than it absorbs from the sun.] So far, this is not too beguiling to the anomalist. But now it seems that other white spots, not as large, have been recorded in 1876, 1903, 1933, and 1960. Could the white-spot phenomenon be periodic--like a percolator?

Many Polynesian navigators did indeed set out from sunswept lagoons into the superficially featureless Pacific. How did these peoples, a thousand years ago, sail reliably from one speck of land to another, thousands of miles distant? The archeology of Oceania confirms that the Polynesians made such voyages centuries before they learned about compasses and navigation satellites. But were these voyages anomalous; that is, did the Pacific peoples possess devices or talents unrecognized today by mainstream science? For the most part, the answer seems to be NO. While the navigational abilities of the Polynesian seafarers seemed supernatural to early European explorers, it has been convincingly demonstrated -- through modern voyages -- that the senses of sight, hearing, smell, touch, and time-passage are and were sufficient for most interisland voyages. The early Pacific navigators were adept at observing the waves, stars, birds, clouds, winds, and several other natural phenomena that carry subtle directional cues. There are, however, modern instances in which Pacific navigators bereft of the usual sensory cues seem to employ an anomalous "sense." B. Finney, in his study of the possibility of human magnetoreception, tells how one native Hawaiian navigator, though wellschooled in traditional Polynesian navigational techniques, conquered the dread doldrums on a 3,000mile voyage from Hawaii to Tahiti in a way ...

Mars is a classic case, being much more heavily cratered in its southern hemisphere than its northern. But the dichotomies are not restricted to cratering, as we shall now see. Neptune . Recently, H.B . Hammel, using the University of Hawaii's 2.2 -meter telescope, discovered that Neptune's northern hemisphere is now brighter than its southern -- something never observed before. During the past eight years, the southern hemisphere has been consistently brighter, although the hemispheres were of roughly equal brightness during the late 1970s. The cause of these brightness changes remains a mystery. (Cowen, Ron; "Neptune's Northern Half Grows Brighter," Science News, 144:287, 1993.) Iapetus . This satellite of Saturn is dark on one half and light on the other. Quantitatively speaking, the bright side reflects ten times more incident light than the other. An explanation is suggested by the fact that the dark side points in the satellite's direction of motion. A recent study of 12 Voyager images of Iapetus also imply an exogenous (externally imposed) origin of the dark surface, because they show a gradual rather than sharp transition between the dark and light regions.

Back in 1986, Soviet researchers reported the observation of neutron emission when they violently crushed lithium deuteride in the presence of ice made from heavy water. More recently, they saw the same phenomenon when milling several deuterium-containing metals. Conceivably, deuterium nuclei accelerated by the electric fields along the cracks could be fusing, producing neutrons. (Amato, I.; "If Not Cold Fusion, Try Fracto Fusion," Science News, 137:87, 1990.) Pouring cold water on the Soviet results, two American scientists described negative results in the February 15 issue of Nature. They fired small (0 .131-gram) steel ball bearings at an ice tar-get made with 99.9 % deuterium.

For example, Van Valen's list of objections to the hypothesis of asteroid impact at the Cretaceous-Tertiary boundary was reproduced in the last issue of Science Frontiers. Now, in a recent issue of New Scientist, T. Hallam raises still more objections: Tropical plants, mammals, crocodiles, birds, and benthic invertebrates were little affected by whatever happened at the Cretaceous-Tertiary interface. Furthermore, many groups that were extinguished were already well into a decline. Some geologists insist that some of the supposedly synchronous extinctions were probably separated by several hundred thousand years; viz., plankton and dinosaurs. The vaunted iridium anomaly in deep-sea cores is spread through a considerable thickness of sediment. Even after allowing for the mixing of sediments, the iridium-rich layer is thousands of years thick. According to the asteroid scenario, the clay layer separating the Cretaceous from the Tertiary should represent the fallout from impact-raised dust, which would include asteroidal material and a mixed sample of earth rocks. However, in Denmark, the boundary is marked by the so-called Fish Clay, which is almost pure smectite -- a single mineral and not a mixture of terrestrial rock flour.

Pratt fired a thunderous broadside at that revered paradigm of geophysics: plate tectonics, nee continental drift. This 47-page study, which includes 10 pages of references, is best summarized by quoting from the author's own conclusions. Plate tectonics -- the reigning paradigm in the earth sciences -- faces some very severe and apparently fatal problems. Far from being a simple, elegant, all-embracing global theory, it is confronted with a multitude of observational anomalies and has had to be patched up with a complex variety of ad hoc modifications and auxiliary hypotheses. The existence of deep continental roots and the absence of a continuous, global asthenosphere to "lubricate" plate motions has rendered the classical model of plate movements untenable. There is no consensus on the thickness of the "plates" and no certainty as to the forces responsible for their supposed movement. The hypotheses of large-scale continental movements, seafloor spreading, and subduction , as well as the relative youth of the oceanic crust are contradicted by a substantial volume of data. Evidence for significant amounts of submerged continental crust in the present-day oceans provides another major challenge to plate tectonics.

But when we examine DNA, we find that only about 3% of the DNA in human cells codes for protein manufacture. The remaining 97% is termed "nonsense" or "junk" DNA. But there may actually be sense in nonsense DNA. Statistical analysis of nonsense-DNA "words" (3 -8 bases long) reveals considerable redundancy. Long stretches of nonsense DNA are definitely not random. In fact, the structure of nonsense DNA resembles that of language.

To survive, animals must eliminate ingested neurotoxins by vomiting or defecation, both of which also accompany motion sickness. It is simply coincidental that modern vehicles duplicate these symptoms through their motions.

Observing Io with a spectrophotometer in 1978, F.C . Witteborn et al measured a brightness increase in the 4.7 -5 .4 micron range that was three to five times the brightness at other phase angles. Long a controversial phenomenon, this confirmation of Io's post-eclipse brightening has led to a search for possible explanations. Witteborn et al suggest that the transient flare-up is a complex thermoluminescent effect excited by interaction with Jupiter's magnetosphere, followed by solar heating as Io emerges from the shadow. (Witteborn, F.C . et al; "Io: An Intense Brightening near 5 Micrometers," Science, 203:643, 1979.) Comment. Io also modulates Jupiter's microwave emissions.

Science Frontiers ONLINE No. 2: January 1978 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects How real are biological extinctions in the fossil record?Much has been made by catastrophists of the apparent wholesale extinctions of many forms of life from one geological period to another. Some uniformitarians have been arguing all along that these so-called extinctions are more apparent than real. The present study supports this view with its study of world-wide records of the Triassic-Jurassic transition period. Correlation of U.S . and South African rocks imply that this key geological interface was actually a period of gradual faunal replacement rather than sudden, simultaneous extinction of live forms.

Science Frontiers ONLINE No. 137: SEP-OCT 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mysterious Losses And Acquisitions of Color Vision The eyes of most mammals incorporate two types of color-sensitive cones; one for seeing blue light, the other for green light. Such mammals have bichromatic vision and discern colors rather well. Humans and the other primates are blessed with trichromatic vision, for their eyes have cones that register red light. Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it is easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on ...

Science Frontiers ONLINE No. 137: SEP-OCT 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Missing Helium The situation now described is analogous to the saga of the "missing solar neutrinos" mentioned under ASTRONOMY. Here, it is our model of the earth's interior rather than that of the sun that is at risk. There is simply not enough helium escaping from earth's crust to account for the heat flowing outwards from our planet's core. You see, most of the earth's internal fires are fueled by the radioactive decay of uranium and thorium. The heat produced by these disintegrations eventually makes its way to the surface where we can measure it. but the helium (4He) created by the radioactive decay of the uranium and thorium is mostly missing. The discrepancy is large, and scien tists are confronted with the possibility that we are wrong about either the source of the earth's heat or the facts of nuclear physics. You can bet it will not be the latter. We are confident that helium atoms cannot change their type like those solar neutrinos! Neither can we blame chemical sequestration because helium is a noble gas. Perhaps the missing helium is physically trapped and stored somewhere in the earth's mantle. No one knows the answer; nor does any one pay much attention to this clearcut anomaly. (Chin, Gilbert, ed. ; "A Scarcity of Gas," Science, 292:2219, 2001.) From Science Frontiers #137, SEP ...

Science Frontiers ONLINE No. 112: Jul-Aug 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Sea turtles: from one end to the other Leatherback turtles are mysterious in several ways: flexible shell, warmbloodedness, etc. (See SF#76 for more.) Now, we add two more remarkable capabilities to their dossier. Precision navigation. The oily, flexible shells of leatherbacks have made it difficult for researchers to attach radio transmitters to the animals. Their very deep dives (over 1,000 meters) are also inimical to human instrumentation. But S.J . Morreale's group at Cornell have succeeded in attaching pressure-resistant transmitters to the shells on short tethers. This team was able to track female leatherbacks as they left their nesting beach in Costa Rica and headed southward, past the Galapagos, out into the open South Pacific. Surprisingly, all the leatherbacks plied a very narrow corridor each year of the experiment (1992-1995). In fact, the paths were almost for at least 2,700 kilometers southwest of the Galapagos. Highprecision navigation equipment is required here. Among the leatherbacks' "instruments" are probably sensors that detect the angle of the geomagnetic field, the length of daylight, and the identities of the oceanic currents encountered. There are probably other sensors and, of course, a brain to process all the signals; but virtually nothing is known about them.

Dumbacher, an ornithologist working in Papua New Guinea, scratched his hand while freeing a hooded pitohui from a collecting net, his first instinct was to suck the wound. This was a bad move, for he immediately experienced a numbing and burning in his mouth. The reason for this, it turned out, was because the skin and feathers of pitohuis are loaded with homobatrachotoxin, a type of poison. This discovery makes the pitohuis the first known poisonous birds. Like many other poisonous animals, the pitohuis also emit a foul odor and advertise their unsavory nature with bright colors. (Dumbacher, John P., et al; "Homobatrachotoxin in the Genus Pitohui : Chemical Defense in Birds?" Science, 258:799, 1992. Also: Anonymous; "Bird with a Sting in Its Tail," New Scientist, p. 10, October 31, 1992.) Comment. As we see from the diagram, homobatrachotoxin possesses a rather complex chemical structure. One wonders how the pitohuis acquired the ability to synthesize it through random mutations. The puzzle deepens when one discovers that homobatrachotoxin is also manufactured by the New World poisondart frogs. Although far-separated taxonomically, both species traveled along the same path of random mutations to achieve this evolutionary convergence.
