The precipitation rate seems to vary with time, being different from one month to the next. This time variation has been confirmed at many laboratories around the world and is not dependent on any obvious meteorological condition. Instead, some investigators claim to have found a rather good correlation with the sunspot cycle! (Majorino, Gianfranco, and Zecca, Luigi; "Period Analysis of the Picardi P-Test," Cycles, 33:78, 1982.) Comment. This precipitation test, called the Piccardi P-Test, has been offered for years by cycle students as proof of extraterrestrial influences on earthly chemistry, including biochemistry. No explanation has been suggested; and one reads about it only in "fringe" publications. From Science Frontiers #22, JUL-AUG 1982 . 1982-2000 William R. Corliss ...

... that virtually no one knows about them. The furor over ALH 84001 has underscored professional and public ignorance of nannobacteria. Some scientists have asserted that bacteria could never be as small as those "objects" seen in the greatly magnified photos of ALH 84001. This claim led R.L . Folk to fire off a letter to Science that began with these two sentences: "Enough! As one of the discoverers of mineralized nannobacteria on Earth*, I must come to their defense. They are so abundant in samples I have studied that I believe they may make up most of the Earth's biomass." Folk reports that nannobacteria are found just about everywhere: hot-spring waters, decaying leaves, even blood. Nannobacteria are key players in the earth's surface chemistry, precipitating a host of minerals and acting symbiotically to precipitate organic hard parts. (Folk, Robert; "In Defense of Nannobacteria," Science, 274:1288, 1996.) Comment. Ignorance of nannobacteria is not surprising. One needs a scanning electron microscope to see them. * See: Folk, R.L .; Journal of Sedimen tary Petrology, 63:990, 1993. From Science Frontiers #110, MAR-APR 1997 . 1997-2000 William R.

This problem along with the fabulous stonework and extensive ruins have precipitated theories involving extraterrestrial visitors and an age for the site in the hundreds of thousands of years. At least the food-supply puzzle now seems to be in hand. Stereoscopic aerial photographs show in startling detail: ". .. immense, curvilinear platforms of earth...these fields form elevated planting surfaces ranging from five to 15 meters wide and up to 200 meters long...Extensive and nearly continuous tracts of these fields -- all of which have been abandoned for centuries -- run from the edge of Lake Titicaca to about 15 kilometers inland, and form virtually the only topographic relief in the broad, gradually sloping plain." Some of the raised fields are remarkably sophisticated in design. At the base is a layer of cobblestones for stability. These are covered by a 10-centimeter layer of clay. On top of the clay are three distinct layers of sorted gravel; all capped by rich organic topsoil. These fields were simultaneously an aquifer for the fresh water percolating down from the surrounding hills and a barrier to the brackish water from Lake Titicaca ...

... women are de-scended from an African "Eve" who lived between 100,000 and 200,000 years ago. This conclusion was based upon mtDNA (mitochondrial DNA) studies that assume that mtDNA is inherited only from mothers. This assumption has been repeated so often that few ever question it. However, two recent studies seem to show that some paternal mtDNA actually does get into eggs and recombines with maternal mtDNA. This unexpected invasion makes the mtDNA clock run more slowly. So, African Eve, if she ever existed, is probably twice as old as originally thought. (Day, Michael; "All about Eve...," New Scientist, p. 4, March 13, 1999.) Maybe There Were Two Eves! Not only has African Eve aged precipitously but there may have been a non-African Eve, too. J. Hey and E. Harris, at Rutgers, have presented data suggesting that the famous African Eve was the mother of only modern sub-Saharan Africans. Everyone else seems to have descended from an entirely different Eve. These data, if confirmed, demolish the African Eve theory and support the often-reviled multiregional theory of humans origins. (Pennisi, Elizabeth; "Genetic Study Shakes Up Out of Africa Theory," Science, 283:1828, 1999. Bower, B.; "DNA Data Yield New Human-Origins View," Science News, 155:181, 1999.)

But one of their most ambitious projects is rarely mentioned in the literature and is poorly investigated in the field. Probably no more than 150 miles in length, it cannot compare with China's Great Wall. Still, it is built at altitudes of 8,000-12,000 feet in extremely rugged terrain. It runs along high ridges and is studded with stone forts at strategic intervals. Even though the Inca Wall is only a few feet high, it would certainly slow down a force charging up precipitous terrain at two miles altitude. The true extent and condition of the Inca Wall is not accurately known. Only a few easily accessible sections have been checked out. The theory is that the Incas built it to discourage invasions by lowland Indians. Like all Great Walls, it seems to have met with only small success. (Paddock, Franklin K.; "The Great Wall of the Inca," Archaeology, 37:62, July/ August 1984.) Comment. The Great Wall of the Incas is located in Bolivia. There is another Great Wall in Peru that seems to have been built by the Chimu people, perhaps to defend themselves against the Incas! The Chimu Great Wall averages 7 feet in height and reaches 20-30 feet where it crosses gullies. Also incompletely explored, it ...

Until now, no one seems to have studied the lunar effect on avalanche frequency; even though avalanches are obvious trigger-type phenomena. We find the following para-graph in an article on snow avalanches in general: "Another precipitating factor may be the gravitational pull of the moon. In research published last year, Peter Lev of the Utah Highway Department found that based on a statistical study of moon and avalanche cycles in the Wasatch Mountains during the past 20 years, the chance of an avalanche's occurring on a full and new moon was 100 times greater than it is during other days in the lunar cycle."

... is formed, only flawless bits of sand remain. Case closed. No anomalist worth a grain of salt would let this delightful phenomenon escape without a bit more study. Do young sandstones with identifiable granitic sources show more inclusions than older sandstones? Do desert sands, beach sands, and other unconsolidated quartz grains show any flaws? Has anyone really examined fresh quartz grains weathered from granite to determine how the number of flaws in a grain varies with the grain size? (Cox, Douglas E.; "Missing Mineral Inclusions in Quartz Sand Grains," Creationist Research Society Quarterly, 25:54, 1988.) Comment. Most geologists will complain that we are going out of our way to make trouble. But consider the possibility that some unflawed quartz grains in sandstones may have actually been precipitated from gases and fluids and not be granitic at all. And what about those sandstone dikes and other sand-stone intrusive bodies? Where did their quartz grains originate? Not all sandstone is sedimentary.

... Science Frontiers ONLINE No. 31: Jan-Feb 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Early Life And Magnetism The tiny granules of magnetite found in magnetized sediments come in various crystalline forms. Inorganic magnetite precipitated from molten rock is octahedral, while the particles manufactured by bacteria are cubes, hexagonal prisms, or noncrystalline teardrops. The magnetite found in marine sediments appears to be organically formed -- at least the shapes of the particles are characteristic of bacterial manufacture. Apparently these industrious bacteria have been busy producing magnetite ever since "lowly" life forms appeared in the Precambrian. These facts pose at least four questions: How much of the earth's iron ore has been concentrated biologically and is there a connection with the Gaia Hypothesis? Is it possible that magnetic field reversals, now believed to be of purely geophysical origin, might be biological artifacts (that is, due to population and/ or species changes of magnetic bacteria)? If magnetic field reversals are of geophysical origin, how do the magnetic bacteria find their food sources during the long periods of near-zero field? Lab experiments prove that magnetic bacteria require free oxygen to secrete magnetite, but the Precambrian atmosphere and oceans were supposedly devoid of oxygen until 2.3 billion years ago. How did the magnetic bacteria prosper before then? (Simon, C.; "Tiniest Fossils May Record Magnetic Field," Science News, 124:308, 1983.)

... think of minerals as having been formed by purely inorganic processes. Only once, on p.000. where biogenic stalactites were described, have we persued the idea that minerals, including crystal forms, might be biogenic. We now have at hand a survey of biogenic minerals. It turns out that biogenic minerals are quite common - so common, in fact, that the Gaia concept is recalled, in which biological processes preside over much that happens upon this planet. Here follows a sampler of some biogenic minerals: Much, if not all, travertine (calcite and/or aragonite) and silicious sinter (opal) are deposited through algal action. Much pyrite and marcasite in sedimentary rocks comes from bacterial sulfate reduction. Bacterial breakdown of oil produces organic complexes that dissolve, transport, and precipitate quartz. The reknowned Herkimer "diamonds" may be of biological origin. Living cells synthesize isometric crystals of magnetite. Mitochondria manufacture crystals of hydroxylapatite. Better known are the apatite in bones and teeth and the aragonite, calcite, or fluorite in the vestibular systems of vertebrates.

Marine biologists, however, have even more reason to feel slighted. To illustrate, the usual picture painted of the abyssal terrain beyond the continental shelves and slopes is one a a frigid biological desert -- endless plains of sterile muck, broken once in a while by oasis-like deepsea vents, where weird tube worms thrive amidst clouds of chemosynthetic bacteria. This is a highly misleading portrayal. The situation, in fact, recalls what happened when biologists first released clouds of insecticides in rain forest canopies, thus precipitating a deluge of uncataloged insects into collecting nets waiting below. Now, instead of a mere million species of insects worldwide, entomologists are thinking perhaps 10 million or more. Will the same diversity prevail in the deepsea muck? C.L . Van Dover believes so: "Away from the vents, in the great ocean plains, life is much less dramatic and often scaled down to minute proportions -- threadlike worms, tiny snails, delicate, transparent clams. Yet, the diversity of animals in the cold abyssal muds, it now appears, may rival the celebrated biodiversity of the tropical rain forests." We now know virtually nothing about this fauna, how it survives, and how it evolved. Millions of undescribed species may be awaiting discovery by research submersibles and deep dredging. ...

Yet, when the ship was at the center of the patch there was no precipitation. Throughout the watch, however, the sea was strongly luminescent.

... and 537. Despite the earliness of the date, there is sufficient detailed information to estimate the optical depth and mass of this remarkable stratospheric dust cloud. The importance of this cloud resides in the fact that its mass and its climatic consequences appear to exceed those of any other volcanic cloud observed during the past three millenia. Although the volcano responsible remains a mystery, a tropical location (perhaps the volcano Rabaul on the island of New Britain, Papua, New Guinea) can be tentatively inferred."

As seen by three of the ship's officers: "At 2230 UTC the observers noted on both the 3-cm and 10-cm radars, as well as visually, a wave or band-like phenomenon shown as a succession of 'bands' approximately 4 n.mile long with a uniform separation of about 0.8 n.mile. "The bands appeared as if they were precipitation but on passing through one of them nothing was observed nor were there any other particles [i .e ., no wind-blown dust], seeing as the vessel was off the West African coast at the time. The bands themselves caused a rippling effect on the sea surface of roughly 150 m wide, giving an otherwise calm sea a black appearance beneath them on what was a well moonlit night. Although the phenomenon looked like rain bands, the observers could not give an otherwise definite solution for it."
