The sunspot peaks have been ascending to greater heights every 11-or-so years. Right now, near the peak of the present cycle, the earth is being bombarded by extra-high fluxes of X-rays, ultraviolet light, and other energetic radiation. A century ago, no one would have noticed or cared, but today our technological infrastructure is suffering. K.H . Schatten has listed some of the "sunburn symptoms" in a recent article in Nature. Fade-outs of over-the-horizon radio communications Greater aerodynamic drag on satel lites and earlier reentry Glitches and outright damage in satellite electrical systems Anomalous induced voltages in elec trical power systems and long-line communications Blackouts of high-frequency polar communications oInduced errors in VLF (Very Low Frequency navigation systems Occasional radiation levels that are hazardous to humans in high-flying aircraft.

Formerly, the Nauruans led energetic lives -- fishing, subsistence farming -- and they were slim and healthy. Then came colonization and phosphate mining; with these came wealth, imported caloriepacked food, sedentary lives, obesity, and, unhappily for this tropical paradise, diabetes. The incidence of diabetes mellitus shot up to 60%, an astounding statistic by world standards. On one of the wealthiest of the Pacific islands, the inhabitants have the shortest life spans! The same scenario is being played out in other parts of the world where life styles have changed drastically; for example, some Polynesians, American Indians, and Australian aborigines are similarly afflicted. Furthermore, an epi-demic of diabetes mellitus is anticipated as the "benefits" of civilization are brought to India and China. Two questions must be answered: (1 ) Why is the incidence of diabetes mellitus only 8% among American junkfood-eating couch potatoes? Probable answer: natural selection has already modified the American genotype by eliminating those who are supersensitive to diabetes mellitus under conditions of rich diets and sedentary lives. (2 ) Why are modern populations still living under Spartan conditions so sensitive to diabetes in the first place? Possible answer: the so-called "thrifty genotype" hypothesis.

J. Gould, who conducts a monthly column in Natural History reviews the sad history of Goldschmidt and his villification by the scientific establishment. Goldschmidt saw the fossil record as woefully inadequate to justify the assumption of gradual evolution of one form into another. Intermediate forms between separate species do not seem to exist in the fossil record and, if they did, they would probably not have been viable creatures. What good is half a wing? Gould believes that Goldschmidt's "hopeful monster" concept will ultimately be dusted off. The key to "macromutation," Gould feels, is not to be found in major gene reorganizations that might produce a whole wing, feathers included, all at once, but rather in changes in the genes that control the development of embryos. Embryos in their early stages are pretty much alike regardless of species. Gould hopes further that the ruling neo-Darwinians will not be so hostile to new ideas and eventually acknowledge Goldschmidt's important work.

That there are closely fitted, rectilinear stones under about 15 feet of water is not in question. The 1- to 10-ton blocks surely look manmade, but are they really? E.A . Shinn describes several "beach-rock" formations in the area, some exposed and some submerged under a few feet of water. This beach rock, as his photos demonstrate, has a natural tendency to fracture into rectangular blocks, creating strips of pavement-like blocks essentially identical to the famous Bimini road. Proponents of Atlantis and other radical archeological theories do not deny the similarity of the formations or even that the natural and supposedly man-made blocks are of the same composition. The Atlanteans, they say, obviously made use of readily available materials, and beach rock was their choice. Shinn goes on to prove to his satisfaction that the Bimini block formations are still in place where geological forces left them about 2,200 years ago. Further, he notes, there are absolutely no traces of human workmanship and no human artifacts in the area. One mystery is admitted, however, in this debunking article; and that is the unanswered question of how the Bimini rocks came to be submerged in 15 feet of water ...

Plant mimicry for purposes of protection (for example, stone plants) and for propagation are well known and, in the logic of evolutionists, have evolved because of the advantages conferred on the species.

This is called cryptic or camouflage mimicry.

But redshifts can also arise from the gravitational attraction of mass.

The quasars all have rather large redshifts, indicating great distances from earth, but the lone galaxy displaying "superluminal" expansion has a redshift of only 0.032. This fact suggests that superluminal velocities cannot be employed as arguments against redshifts being cosmological; that is, measures of distances from earth. Therefore, if the redshift is truly a measure of distance (as it seems to be), some astronomical structures (perhaps not matter itself) seem to grow faster than the velocity of light.

Gold and S. Soter, from Cornell, have championed the theory that earthquake lights, sounds, and precursory animal activities may be due to abiogenic natural gases escaping from deep within the earth. Perhaps some petroleum and natural gas reserves have been created by primordial hydrocarbons working their way outward through the crust rather than by the geochemical alteration of biological materials. Perhaps almost all petroleum is abiogenic -- some Russian scientists hold this view! Western scientists are almost unani-mous that natural gas and oil are bio genic with maybe a touch of upwelling abiogenic hydrocarbons. A major reason given for this stance is that the biogenic theory has been so productive in locating hydrocarbon reserves. This, of course, leaves the earthquake lights and sounds still unexplained.

Certain plant tissues (etiolated or dark-grown) act as multiple bundles of optical fibers and coherently transfer light over distances of at least 2 cm. Optical tests show that these natural light pipes are much more effective transmitters of light than media that simply scatter light. This unsuspected sophistication of Nature's design may require significant revisions in photobiology, which did not allow for such ingenuity.

Some of the bacteria even live inside the protozoa and other bacteria forming ecosystems of several symbiotic levels within each termite.

That termites had bugs in-side them has long been known; but the new-found complexity and interdependency of life systems within life systems is remarkable.

During the following half-century, scientists have been studying this perplexing problem, but it has been the amateurs who have accumulated the bulk of the data. Over 100 reports exist where echoes of radio transmissions were received seconds later at the original transmitting station. Since light travels 186,000 miles per second, any simple radio-wave reflector would have to be well beyond the moon's orbit. A wide variety of natural phenomena (interplanetary matter) and even artificial devices (alien space probes) have been postulated to explain the long delays. Muldrew's article is first of all an excellent summary of the long and fascinating history of this effect. His bibliography is extensive and apparently nearly complete. Muldrew next examines the various ionospheric mechanisms that might cause long delays. The ionosphere is a complex structure with ducts in which radio signals can get trapped. Delays of a second or so might be due to such trapping but the longer delays require some other explanation. Muldrew favors a rather complex interaction between signals from separate transmitters that (theoretically at least) can create a long-lived electrostatic wave that travels in the ionosphere -- a sort of natural memory device. The coded signals could then be read out much later when the proper natural conditions developed. Delays of up to 40 seconds might be possible with this "ionospheric memory ...

To him, the record of death in the layers of fossiliferous rocks was obviously the consequence of terrestrial convulsions. But Cuvier's ideas were swept aside by the uniformitarians who saw the earth and its cargo of life unfolding with almost agonizing slowness. But Cuvier is making a comeback, as illustrated by the following back-to-back articles in Nature. We quote from the abstracts. "Closely spaced samples from an uninterupted calcareous pelagic sequence across the Cretaceous-Tertiary boundary reveal that the extinction of planktonic Foraminifera and nannofossils was abrupt without any previous warning in the sedimentary record, and that the moment of extinction was coupled with anomalous trace element enrichments, especially of iridium and osmium. The rarity of these two elements in the crust of the Earth indicates that an extraterrestrial source, such as the impact of a large meteorite may have provided the required amounts of iridium and osmium." (Smit, J., and Hertogen, J.; "An Extraterrestrial Event at the Cretaceous-Tertiary Boundary," Nature, 285:198, 1980.)

"It has been suggested that the evolution of man took place in Africa. This suggestion results from the unusual abundance of fossil material in Africa that is quite ancient in comparison with what is known elsewhere. The theory of an African origin has influenced the interpretation of the age of some non-African archaeologial sites. A case in point is the 'Ubeidiya locality in Israel, which is generally considered to be about 700,000 yr old because it has been assumed by a few that the associated Early Acheulian tool industry, and the persons who used it, would have taken considerable time to disperse from Olduvai Gorge to this non-African site in Israel. Here we evaluate fossil mammals from 'Ubeidiya, which are stratigraphically and directly associated with Early Acheulian artifacts, and find no substantial reason for considering the locality younger than 2Myr, and possibly as much as 500,000 yr older than any record of Early Acheulian artefacts or Homo erectus in Africa."

To everyone's surprise, the article elicited some 800 letters from others who heard hums. Amazed by the magnitude of the problem, doctors began examining some of the afflicted. In a few cases, the hum seemed to be internally generated -- something akin to tinnitus, which causes one to hear a highpitched whine. Many others, however, heard a 40 Hz hum modulated at 1.6 kHz, and apparently of external origin. The hum sufferers were inclined to blame industrial noise, but no obvious sources could be uncovered. The hum investigators have considered sea noise, jetstream noise, and other natural sources. Whatever the source, most people do not hear it at all. It is possible that a small percentage of the population is abnormally sensitive to sound at 40 Hz. (Wilson, Steve; "Mystery of People Who Hear the Hum," New Scientist, 84:868, 1979.) Comment.

Pollen studies of the core indicate a brief decline of forest pollen about 17,800 BP along with increased sedimentation characteristic of cleared land. Taken by themselves, these data would probably be interpreted in terms of natural climate changes. But extremely early dates for human activity exist nearby: 14,000 BP for agriculture in Thailand and 11,000 BP for forest clearance on Taiwan.

He also points out that the aborigines of North America, Australia, and Siberia all called the Pleiades the "Seven Sisters." Coincidence is very unlikely here, he says.

The first class of observations consists of blasts of hot air noted some distance from violent lightning strikes but seeming associated with the discharges. Second, some superhailstones (hydrometeors) also seem to be correlated with violent lightning. The physical mechanism for the concentration and propulsion of matter is the electrostatic force naturally present in lightning discharge channels; it functions much the same as the particle accelerators in the physics lab.

Science Frontiers ONLINE No. 8: Fall 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Convergent evolution or chance look-alikes Why should caddis fly larvae and a species of aquatic snail look alike? Mimicry is rather common in nature for it often confers some sort of advantage to one or both of the species in the turmoil of evolutionary pressures. Or so the theory goes. Most examples of convergent evolution involve closely related species. In the present case, though, the species are in different phyla. The caddis fly larva builds its snail-like shell by cementing grains of sand together with a silk-like secretion, while the snail's shell is a calcareous excretion. One would expect a strong advantage to be conferred on one or the other species, especially in the matter of predation. Using brook trout as predators, how ever, proved perplexing, for the trout would eat only the snails, avoiding the carbon-copy larvae. (Berger, Joel, and Kaster, Jerry; "Convergent Evolution between Phyla...." Evolution, 33:511, 1979.) Comment. This is a remarkable case of mimicry. One wonders how the caddisfly larvae know exactly what snails look like, and how the unique shell constructing methods were coded into its genes by evolution. Or did the snail emulate the larvae?

... Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The gravitational "constant" is not!For too many years, physicists have been content with laboratory determinations of G (the gravitational constant) using the old Cavendish Balance. In this paper, Stacey and Tuck offer a disturbing collection of values of G determined from geophysical measurements; i.e ., measurements in mines, boreholes, and under the sea. These measurements are unanimous in producing G's that are larger than the usually accepted value by about 1%. Furthermore, the deeper the experiment, the greater the departure from the standard value. (Stacey, F.D ., and Tuck, G.J .; "Geophysical Evidence for Non-Newtonian Gravity," Nature, 292:230, 1981.) Comment. These geophysical measurements must be added to recent laboratory experiments indicating that gravity may not be best described by an inverse square law.

... about 20/km/sec. Do the theoretical results jibe with the geological and paleontological data? Very definitely. 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.

... enough, the moon-modulated matings of these worms seem to improve reproductive efficiency. Less well known are many other moon-synchronous biological rhythms; viz., the sizes of the pits dug by ant lions to trap ants and the angles flatworms assume in swimming away from light. Many such lunar rhythms apparently have no adaptive value whatsoever. So, why do they exist? Even more disconcerting is the fact that lunar rhythms persist in the lab where the moon is not visible. Are internal clocks responsible here? If so, how do they work and how are they set? These questions are hard to answer if the rhythms have no value to the organism's success. (Palmer, John D., and Goodenough, Judith E.; "Mysterious Monthly Rhythms," Natural History, 87:64, December 1978.) Comment. It would, or course, be outright heresy to suggest that heavenly bodies may be the sources of unrecognized but biologically significant forces. Reference.
