... artifacts older than Clovis points. Dated at 10,800-11,200 radiocarbon years, Clovis points supposedly marked the earliest arrival of humans in the Americas. Digging deeper at the Topper site would have been a waste of time. In 1998, however, Goodyear had second thoughts. This was the time when the nothing-older-than-Clovis paradigm was being challenged by finds at Monte Verde, Chile. (SF#120) Goodyear decided to take his trowels back to the Topper site. "After some 40 cm of essentially barren deposits, the excavators began finding small flakes and microtools. The lower level, exposed over 28 square meters, has yielded some 1,000 waste flakes, 15 microtools (mostly microblades), and a pile of 20 chert pebbles plus four possible quartz hammerstones." Goodyear thinks that chert pebbles were being processed at Topper 12,000-20,000 years ago. Apparently, North America has its own Monte Verdes! (Anonymous; "Pre-Clovis Surprise," Archaeology, 52:18, July/August 1999.) Comment. Shouldn't Goodyear keep on digging at Topper?

... swarm of Moodus quakes that have puzzled generations of earth scientists. The earliest was recorded in 1568 and Indians knew of them long before then: Moodus is an Indian word meaning 'place of noises.'" Sullivan's article was derived from a spate of scientific papers delivered at the Spring meeting of the American Geophysical Union. (Sullivan, Walter; "A Connecticut Mystery Still Defying Scientists," New York Times, May 22, 1988. Cr. P. Huyghe, D. Stacy, R.M . Westrum) Abstracts of all the scientific papers presented at the meeting of the American Geophysical Union appeared in Eos. Here are excerpts from one of them: "Since the installation of a six-station microearthquake network in the Moodus, Connecticut, area in 1979, four extensive microearthquake swarms of several months duration each, all accompanied by main shocks of Mc greater than 2, have been recorded. All of the swarms have occurred at shallow depths (less than 2.3 km) and have been concentrated primarily in one small source volume... The 1986 swarm was characterized by a number of small bursts of activity culminated by the largest event near the end of the swarm. The 1987 swarm behaved in a very similar temporal manner to that of the 1986 swarm with one strong difference in that the largest event was the first one in 1987...the shallow depths of all the earthquakes there, the small lateral dimensions of the active source volume and the lack of a fault to which the earthquakes can be ascribed make it difficult to argue ...

Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Terrestrial maria?Those dark patches that constitute the face of the man-in-the-moon are really huge outpourings of lava. Once considered real seas, they are called "maria." Maria like those on the moon also exist on the earth. This is a surprise because terrestrial maria were never mentioned in my college geology courses. But, in those days, the one-mile-wide Meteor Crater, in Arizona, was the largest accepted consequence of celestial bombardment. Deccan basalt flows (also called the Deccan traps) in Western India, shown before the formation of the Carlsberg Ridge and teh splitting off of the the Seychelles. D. Alt and colleagues, at the University of Montana, have identified four large basalt plateaus that might be terrestrial maria: "Notable examples of large lava plateaus that resemble lunar maria include, among others, the Deccan Plateau of India, the Columbia Plateau of western North America, the Parana Plateau of South America, and the Tungusska Basin of Siberia. All consist mostly of basalt lava flows; those on continents include minor quantities of rhyolite, and variable amounts of sediment. All seem to have appeared suddenly, within plates. No consistent context of plate interactions explains them. We suggest that large lava plateaus are indeed terrestrial maria." Alt et al go on to show that these lava plateaus seem to have initiated continental rifts and hotspot tracks where none existed before. A reasonable inference is that these plateaus are the consequence of the impacts of large meteorites. ...

... And before the settlers plowed them up, there were travel-worn trails six feet deep in the earth of Iowa. Now, we learn that, indeed, the Hopewell Culture may have built a long road mainly for ritual processions. It is called the Great Hopewell Road, and it is thought to connect the Hopewell centers at Newark and Chillicothe -- a distance of 60 miles through the heart of Ohio. In 1862, the first 6 miles of this controversial road, marked by parallel earthen banks, were surveyed by two brothers, C. and J. Salisbury. They noted that the road extended much farther in the direction of Chillicothe. B. Lepper, a present-day champion of the Great Hopewell Road, claims that there are still traces of the road remaining at four additional places along the 60-mile line connecting Newark and Chillicothe. Skeptics do not question that the sophisticated Hopewell Culture (circa 200 B.C . to 400 A.D .) was capable of constructing such a road, nor do they contest the 1862 survey covering the first 6 miles. They doubt the existence of the last 54 miles. (Hicks, Ronald; "The Great Hopewell Mystery," Archaeology, 52:76, November/December 1999.) From Science Frontiers #127, JAN-FEB 2000 . 1997 William R.

In the five years that have transpired, Galileo has radioed back voluminous data about Jupiter itself and its four large Calilean satellites. These natural satellites have turned out to be a disparate bunch. Three have iron cores, but Callisto breaks the mold with an unusual core of mixed ice and rock. Europa probably possesses an ocean, and Callisto might also. Only one of Jupiter's large satellites, Ganymede, boasts a magnetic field. In fact, Ganymede is apparently the only satellite in the solar system to display an intrinsic, dipole magnetic field like the earth's . Although Ganymere's magnetic field is like that produced by a permanent bar magnet, its core is much too hot for permanent magnetism. Again like the earth, Ganymede's field is theorized to be generated by the convection of electrically conducting liquid in its core -- a dynamo of sorts. All well and good, but Ganymede is so small that it should have cooled off billions of years ago thereby freezing its metallic core. So then, whence its magnetic field? One way out of this box it to suppose that about a billion years ago Ganymede was circling Jupiter in an orbit that took it much closer to this ponderous planet. Then, Jupiter's powerful ...

... is searching for a "third way," a scientific, non-Darwinian way. Shapiro maintains that five decades of genetic and molecular-biology research have transformed our vision of life. Ile compares the conceptual changes to those accompanying the transition from classical physics to relativity and quantum mechanics. This new theory of evolution -- his "third" way -- will emerge from the convergence of biology and information science. Genomes, asserts Shapiro, are not really the static "beads on a string" envisioned by the Darwinians. Rather, they are fluid and complex. Genes are now seen as multipurpose elements that turn on and off as required for the survival and well-being of the organism they belong to. In this paradigm-eroding paper (referenced below), Shapiro describes four categories of molecular discoveries that have revised our thinking about how evolution works: (1 ) Genome Organization; (2 ) Cellular-Repair Capabilities; (3 ) Mobile Genetic Elements and Natural Genetic Engineering; and (4 ) Cellular Information Processing. He then writes: The point of this discussion is that our current knowledge of genetic change is fundamentally at variance with neo-Darwinist postulates. We have progressed from the Constant Genome, subject only to random, localized changes at a more or less constant mutation rate, to the Fluid Genome, subject to episodic, massive and non-random reorganizations capable of producing new functional architectures. Inevitably, such a profound advance in awareness of genetic capabilities will dramatically alter our understanding of the evolutionary process. Toward the end, Shapiro approaches, as ...

"Numbers of first admissions per month for a single psychiatric unit, from 1977 to 1987, were examined for 1829 psychiatric inpatients to assess whether this measure was correlated with 10 parameters of geophysical activity. Four statistically significant values were 0.197 with level of solar radioflux at 2800 MHz in the corresponding month, -0 .274 with sudden magnetic disturbances of the ionosphere, -0 .216 with the index of geomagnetic activity, and -0 .262 with the number of hours of positive ionization of the ionosphere in the corresponding month. Percentages of variance accounted for were very small." Quite understandably, these investigators concluded: "How to interpret properly associations of solar activity with human behaviors is yet impossible. The relative indifference of behavioral scientists to this question may reflect lack of an adequate theoretical framework relating to the question and the phenomenon."

... Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Search-and-destroy sperm Even book reviews can yield delightful anomalies. Take, for example, the January Scientific American review of Human Sperm Competition, by R.R . Baker and M.A . Bellis. Baker and Bellis have advanced the Kamikaze-Sperm Hypothesis. (SF#78) Central to this idea is the observation that the sperm of many animals, including humans, are polymorphic. They come in a variety of shapes and sizes, some of which are patently unsuited for penetrating an egg. Baker and Bellis draw upon their own studies and classifications of sperm types as well as research by R.A . Beatty and D. Ralt. They assert that sperm come in at least four varieties: "Fertilizers," the egg-penetration specialists, "Blockers," the ones that construct copulatory plugs to prevent further insemination, "Search-and destroy sperm" that hunt down as kill "enemy" sperm from other sources, "Family-planning sperm" that kill all sperm. One can liken this array of sperm types to polymorphic ant colonies with their castes of workers, soldiers, and queen. Baker and Bellis go further and suggest that the numbers of each sperm type are under the control (certainly not conscious control) of the males. For example, where promiscuity is observed, as is common in chimpanzee troops, the numbers of seek-and-destroy sperm are very high. All this out of a short review! Unfortunately, the book ...

... those slabs of beach rock that comprise the controversial Bimini "road" in the Bahamas. Future study of the "wall" will doubtless narrow the list to one. Meanwhile, let's take a look at the wall itself. B. Brailsford, of Christchurch, has been the chief investigator of the Kaimanawa wall, aided by American D.H . Childress, and others. The stones that make up the wall are 4-ton blocks of ignimbrite, a soft volcanic rock that could have been easily dressed with stone tools. The wall is topped by a red beech tree 2.9 meters in circumference and over a meter of accumulated humus. According to Brailsford, who was interviewed by the Listener : "There was no doubt that the stones had been cut. The four visible stones in the front wall were a uniform 1.6 metres tall, and 1 metre wide. In one place he could insert his arm into a root-ridden cavity and feel the back face -- and the front face of the next tier. The faces were uncannily smooth, with no saw or adze marks. The interstices where the blocks join were knife-blade thin. "Further up the hill, the tops of other stones protruded, suggesting a more extensive structure was buried in the hill." Supporting the contention that a pre-Maori people lived in New Zealand are the bones of the kiore, a type of rat alien to New Zealand, which was likely introduced by the first settlers. Some kiore bones have been dated as 2,000 years ...

In it, J. Horgan plays dirges for four phenomena that have received considerable attention in Science Frontiers: (1 ) minicomets; (2 ) cold fusion; (3 ) abiogenic oil; and (4 ) the fifth force. (Apparently Benveniste's "infinite dilution" work has already been in terred.) (Horgan, John; "Death Watch," Scientific American, 262:22, June 1990.) But wait, there is a microwave flicker of life remaining in the minicomets. J.J . Olivero and his colleagues at Penn State have been monitoring the sky with a microwave radiometer in their search for emissions from high-altitude gases. During more than 500 days of observations, they detected 111 sudden bursts of water vapor. Olivero et al suggest that these bursts occur when small, icy comets vaporize at very high altitudes. These minicomets are of the same size (about 100 tons) and frequency (20 per minute over the whole atmosphere) as those predicted by L.A . Frank. Frank's icy comets have been received with about as much warmth as "cold fusion." One reason for the unpopularity of icy comets is that they would have provided sufficient water to fill the ocean basins, thus undermining the accepted view that our oceans derived ...

This fact does not mean that it is easy to understand. In fact, there are eight competing "interpretations" of quantum mechanics, none of which is completely convincing. No wonder, because quantum mechanics implies four characteristics of the universe that are seriously at odds with our everyday experience: The quantization of the properties of matter; The probabilistic nature of physical measurements; Entanglement; that is, the mysterious instantaneous connection of objects and processes across immense distances; and Superposition; for example, an electron is both here and there until we look at it! A. Zeilinger, University of Vienna, advances the idea that we can truly understand quantum mechanics only when we discover an underlying principle -- something akin to the concept of energy which led to the quantification of the laws of thermodynamics. (Incidentally. we only think we know what energy is, but it is a human construct and is not a physical dimension like mass or distance.) Zeilinger asserts that the underlying principle of quantum mechanics is the quantization of information. Every inquiry science makes into the nature of the universe, says Zeilinger, can be reduced to a yes-or-no question; i.e ., a 1 or 0. To a scientist, nature is really like a person on a ...

... speculation about the 1908 Tunguska Event assumes an external cause: a meteor, a comet, an asteroid, or even the accidental explosion of an alien spaceship. A recent meeting of Tunguska experts in Russia looked down rather than up for Tunguska's initiating phenomenon. In this open-minded review, two little-publicized but highly pertinent Tunguska observations were discussed. The catastrophe had five centers of destruction rather than one. At the Tunguska site are many large root stumps, not yet rotted away, that cannot be linked to any pits associated with their origin. These stumps were apparently blown out of the ground and hurled dozens of meters from where they stood prior to the Event. Next to be considered were the unappreciated similarities between the Tunguska Event and the 1883 explosion of Krakatoa. The four bright nights in Europe and western Asia, straddling 30 June 1908, are remimiscent of the 1883 Krakatoa outburst, they ask for transient scatterers in the upper atmosphere, above 500 km, at heights which only methane and hydrogen are light enough to reach in sufficient quantity. Fast-rising natural gas has been repeatedly detected in recent years, in the form of "mystery clouds"---by airplane pilots---and indirectly as pockmarks on 6% of the sea floor. In other words, Tunguska might well have been---not an extraterrestrial impact---but a simultaneous outburst and detonation of natural gas from five closely spaced vents. The report continues with pro-andcon discussions, concluding that this outrageous hypothesis cannot be dismissed! (Kundt, Wolfgang ...
