C.J .H . Hartnady believes he had found the culprit. It is somewhat larger than expected (300 kilometers in diameter instead of 100200), but it is of the right age. Supporting this notion is the observation that the Seychelles Bank and Madagascar suddenly shifted their locations at about this time. (Murray, M.; "Point of Impact: The Indian Ocean," Science News, 129:356, 1986.) The existence of another terrestrial cat aclysm at an earlier date is suggested by a layer of shattered crustal rock fragments stretching over at least 260 kilometers in South Australia. Folded within Precambrian marine shales, these fragments reach 30 centimeters in diameter and show evidence of vertical fall. Evidence points to an origin near Lake Acraman, about 300 kilometers west.

Science Frontiers ONLINE No. 115: Jan-Feb 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Evolvable Hardware First, you must envision a computer chip as an evolvable entity -- an array of logic gates that can be connected in an almost infinite number of ways. A soft-ware instruction becomes the equivalent of a biological gene. Software instructions can be changed to achieve certain hardware goals just as genes can be rearranged to modify an organism. Furthermore, human operators can specify a hardware goal to the chip and let it evolve on its own, something it can do in microseconds rather than millions of years. This is not a frivilous subject. D. Fogel, chief scientist at Natural Selection, Inc., in La Jolla, California, asserts: "Eventually, we will need to know how to design hardware when we have no idea how to do it." A few demonstration devices have already been built, and in them we see something worthy of note for Science Frontiers. One such device, built by A. Thompson, University of Sussex, was tasked to identify specific audio notes by certain voltage signals. Given 100 logic gates, the device needed only 32 to achieve the result. The surprise was that some of these working gates were not even connected to others by normal wiring. Thompson admitted that he had no idea how the device worked. Something completely unexpected had evolved. Perhaps, thought Thompson, some of the circuits are coupled electromagnetically rather than by wires. Human engineers would never ...

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 ...

Some physical scientists claim rather imperiously that the dinosaurs and many other species were done in by the impact of a huge asteroid/meteorite. The worldwide iridium spike is conclusive, they say. Many paleontologists and geologists, however, remain unconvinced and prefer widespread volcanism. We have already covered the various arguments in past issues of Science Frontiers; here, we want to advise our readers that a pair of excellent articles by principals in this debate have appeared in Scientific American. Generally speaking, it seems that the proponents of the impact theory are now listening to the other side. For example, multiple impacts are now proposed to account for evidence of the type introduced below.

No need to recapitulate all that hype. What we do add is the observation that this same sort of excitement has swept through the scientific community at least twice before. Back in 1961, B. Nagy et al discovered tiny particles resembling fossil algae in carbonaceous chondrites. They called these particles "organized elements." Ultimately, these curious particles were explained as natural crystals and terrestrial contaminants. (Ref 1.) Much earlier, in 1881, Hahn, an eminent German geologist, asserted that he had examined thin sections cut from chondrites and found fossils of sponges, corals, and crinoids. In fact, the extraterrestrial coral that Hahn found even received the scientific name Hahnia meteoritica ! In the end, though, Hahn's meteoric life forms met the same fate as the "organized elements" of Nagy et al. (Ref. 2) Ref. 1.

Landers, California. An earthquake of magnitude 7.5 shook this small town. In apparent sympathy with the Landers disturbance, seismic activity appeared from one end of California to the other, as well as in Nevada, Utah, Idaho, and Wyoming. The Landers quake stimulated unusual seismicity in the solid black areas. Yellowstone Park, Wyoming. Here, 1100 kilometers from Landers, the geyser Echinus, which had been erupting on a regular schedule of every 56 minutes, went berserk. It didn't settle down for 34 hours. Geyser eruptions are frequently disturbed by nearby quakes, but Landers was hardly nearby! The seismology community. "Those distant shocks have startled seismologists as well as ordinary residents. Conventional thinking, at least among U.S . researchers, holds that stress generated when a fault slips in an earthquake peters out within a distance equal to a couple of times the length of the ruptured fault. For Landers, where about 70 kilometers of fault ruptured, this would amount to only about onetenth of the observed reach." Seismologists are now searching for ways to account for these unexpectedly far-reaching effects. (Monastersky, Richard; "Yellowstone Geyser Shows Quake Effect," Science News, 142:428, 1992.

Some of these decay reactions produce helium -- so-called radiogenic helium. But, as the following excerpt asserts, the amount of helium actually detected is way out of line with the measured heat flow. "The present rate of mantle heat loss, however, is out of equilibrium with the rate of helium loss -- too large by about a factor of 20. Either radiogenic helium is accumulated in the mantle while heat escapes or current models for the bulk chemistry of Earth are in error and much of the terrestrial heat loss is nonradiogenic."

Even staunch anomalists will have to close the book on the solar-neutrinodeficit problem. No deficit really exists because the neutrinos emitted by the sun change while in flight from a type that is easy to detect to a type that is difficult to register experimentally. The total number of neutrinos reaching the earth is what it should be according to theory but we have not been able to detect them all. This neutrino schizophrenia has now been confirmed, and our theory about how the sun works is safe. But the erasure of the solar-neutrinodeficit problem tells the particle physicists that neutrinos do indeed change type, which implies that they possess mass. But anomalies are sometimes contagious. The Standard Model of particle physics, so successful in many respects, is now ailing. It asserts that neutrinos cannot change types and do not possess mass.

This is another "spooky" prediction of quantum mechanics theory. This prediction was recently verified by W.M . Itano et al, at the National Institute of Standards and Technology, in Boulder. They employed radio waves to drive beryllium ions from one energy level to another. While the beryllium ions were jumping from one level to another, the researchers sent in short pulses of light to determine the ion's state. The more frequently they inter rogated the ions, the less apt they were to jump to new energy states, despite the stimulating radio waves.

On July 26, 1983, Io suddenly brightened by about 50% for just under 2 minutes. The "flash" represented an emission of energy of some 1028 ergs, which is equivalent to the impact on the satellite of an ice mass 5-kilometers in diameter moving at 60 km/sec. This collision interpretation is encouraged by the 1994 impacts of cometary fragments on Jupiter proper. In the case of Io, however, there is another possibility: electrical arcing. Io's volcanoes are prodigious spewers of metallic sodium, and T. Gold has speculated that colossal arcs may occur in this conducting environment as Io cuts through Jupiter's magnetic field. (See Science Frontiers #10. (O 'Brien, Roger; "Has Jupiter Flashed Before?" British Astronomical Association, Journal, 104:6 , 1994.) Comment.

Fairbanks is a paleooceanographer at the Lamont-Doherty Geological Observatory. Recently he has been drilling deeply into the submerged coral reefs off Barbados. During his research, it has been discovered that the radiocarbon (C1 4 ) scale is in serious error beyond 10,000 years BP. Radiocarbon dating is widely used in archeology, but it has always been hard to estimate how much radiocarbon was present in the earth's atmosphere thousands of years ago. As a matter of fact, even before Fairbanks' discovery, a major correction to the radiocarbon time scale was made using tree-ring counts as an absolute reference. But tree ring data go back to only about 10,000 years. The latest correction was made by E. Bard, also at Lamont-Doherty, who took Fairbanks' coral cores and compared the radiocarbon dates with uranium-thorium dates. The result is that at 20,000 BP, the radiocarbon date is 16,500 BP, 3500 years too low. [Of course, all this as sumes that the uranium-thorium dates are accurate.] Use of the newly corrected radiocarbon scale has pushed the peak of the Ice Ages back from 18,000 BP to 21,000 BP. But there is more. The same article in Science, without saying how he came up with the number, has Bard fixing the ...

The test compared accurately measured gravity values along the 600 m WTVD tower near Raleigh, North Carolina, with upward, continued gravity estimates calculated from ground measurements. We found a significant departure from the inverse-square law, asymptotically approaching -547 36 microGal at the top of the tower. If this departure is derived from a scalar Yukawa potential, the coupling parameter is alpha = 0.023, the range is lambda = 280 m, and the Newtonian Gravitational Constant is G = (6 .52 0.01) x 1011 m3 kg-1 s-2 . We do not yet have adequate resolution to discriminate this scalar model from a scalarvector model."

Most scientists and laymen assume that black holes are proven, well-observed denizens of the cosmos. Certainly the media entertains no doubts! Let us take a skeptical look. Does theory require black holes? In 1939, R. Oppenheimer and H. Snyder showed on paper that a massive star could collapse and create a black hole, assuming the correctness of stellar theories and General Relativity. Initially, scientists were skeptical about black holes because of their bizarre properties: They emit no light and inhale unwary starships. Black holes are also singularities, and singularities make scientists nervous. In the black-hole singularity, thousands of stars are swallowed and compressed into an infinitesimally small volume. (Ref. 1) This grates against common sense. The philosophical uneasiness about black holes is worsened by the discovery that they: ". .. threaten the universe with an irreversible loss of information, which seems to contradict other laws of physics." (Ref. 2) Adding to these problems are nagging doubts about General Relativity, which underpins black-hole theory. Recently, some theorists have shown that General Relativity requires that two bodies of approximately equal size not attract one another! (Ref. 2) Despite all these qualms, black holes have become a fixture of astronomy because they promise to explain the incredibly powerful energy sources ...

They are concentrated no deeper than 20-25 kilometers down. However, a few extremely deep quakes rumble at depths of about 600 kilometers. On June 8, 1994, what may be the largest deep earthquake of the century -- magnitude 8.2 -- exploded 640 kilometers beneath Bolivia. "Exploded" may or may not be the proper word. Geophysicists are really not certain what causes the very deep quakes, because at 640 kilometers rocks are so hot that they flow rather than snap under geological stresses. The more common, shallow earthquakes are generally created when rocks snap and fracture. Since the deep quakes seem to be concentrated in subducted slabs of terrestrial crust that plunge down deep into the earth's mantle, geophysicists suppose that the increasing heat and pressure applied to the descending slabs may cause "explosive" phase changes in minerals contained in the slabs. Phase changes often involve volume changes that, if sudden, might generate seismic waves. Too, water of hydration in minerals may be explosively turned into vapor. But this is all surmise at present. The Bolivian quake also caused the whole earth to ring like a bell. Every 20 minutes or so, the entire planet expanded and contracted a minute but detectable amount. Another surprise: the Bolivian earthquake was felt a far away as Seattle -- the first time that a quake in that part of South ...

The so-called Cambrian Explosion has been the subject of two SF items (SF#60/187 and SF#85/ 187). A paleontological fact of life is that all known body plans (phyla) seem to have evolved suddenly -- within a few million years -- after the onset of the Cambrian period some 545 million years ago. Evolutionists are understandably uncomfortable with such a high rate of evolutionary innovation. Nothing like the Cambrian Explosion appears in the hundreds of millions of years of geological strata that followed. So rapid was speciation during the Cambrian Explosion that doubt is cast upon the accepted mechanisms of evolution: slow, stepwise accumulation of mutations plus natural selection. (Refs. 1 and 2) But G.A . Wray and colleagues seem to have rescued Darwinism. They have analyzed the DNA sequences of seven genes found in living animals. Assuming that these genes mutate at constant rates and working backwards in time, they calculate that animal diversification (i .e ., when chordates diverged from invertebrates) actually began about 1 billion years ago, rather than about 545 million years ago. This expansion of the time frame gives accepted evolutionary processes much more time to innovate and create all those new body plans. The evolutionists are pleased. The paleontologists, however, are in a quandry. They see nothing -- or very little -- in the Precambrian fossil ...

We humans know to our dismay that we have the capacity to modify the earth's environment, but could we perhaps exercise better judgment and terraform Mars? C.P . McKay et al have looked into this possibility: "From our analysis, one could propose the following sequence of events: production of CFCs (or other greenhouse gases) starts on Mars and the surface temperature warms up by about 20 K. The regolith and polar caps release their CO2 and the pressure rises to 100 mbar. One of two things could then happen. If there were large regolith and polar CO2 reservoirs, the pressure would continue to rise on its own. If these were absent, the CO2 pressure would stabilize, and additional CO2 would have to be released from carbonate minerals. At this point (perhaps between 100 and 105 years) Mars may be suitable for plants. If there was a mechanism for sequestering the reduced carbon, these plants could slowly transform the CO2 to produce an O2-rich atmosphere in perhaps 100,000 years. If sufficient N2 could also be released from putative soil deposits, and the CO2 level kept low enough, then a human- breathable atmosphere could be produced. (McKay, ...

They are thought to be bacteria, for they closely resemble modern cyanobacteria. What is most important about these fossilized micro-organisms is that they were found in the Apex chert of Western Australia. The Apex chert is designated Early Archean and assigned an age of 3.465 billion years [Four significant figures!]. It is rare to find any fossils at all in rocks this old, but apparently the Apex chert escaped most of the fossil-destroying metamorphism afflicting most Precambrian formations. Even more remarkable is the diversity of these suspected bacteria. J.W . Schopf reports finding no less than eleven different kinds so far--and our planet was only a few hundred million years old at the time the Apex chert was formed. Schopf's discoveries generate at least three questions: How could life have originated and diversified to such an extent in just a few hundred millions years? Why after such rapid diversification did these microorganisms remain essentially unchanged for the next 3.465 billion years? Such stasis, common in biology, is puzzling. If these microorganisms are really cyanobacteria, they would have released oxygen to the atmosphere. Is the standard assumption that the earth's atmosphere lacked oxygen until 2.2 billion years ago correct? (Schopf, J. William; "Microfossils of the Early ...

This was the time of the well-publicized, but still hypothetical, asteroid impact. It is said to have wreaked havoc on our wounded planet and, especially, the dinosaurs. Volcanos spewed out vast lava fields and filled the air with greenhouse gases and dust. It was a bad time for many life forms. Actually, It may have been far worse than generally advertised. In addition to the volcanic activity and climate change, the shock of the asteroid impact could have been sufficient to destabilize the immense amounts of methane hydrate that have long been locked up, frozen and dormant, in oceanic sediments all over the world. According to this scenario, once the shock of the asteroid impact released the methane from its icy prison, it rose to the surface of the oceans in a world-wide burp. Methane, unfortunately for the dinosaurs and many other life forms, is highly flammable. Lightning could have ignited it almost immediately if it was concentrated enough. A colossal firestorm might have then enveloped the entire planet. The whole atmosphere could have been afire. This, according to B. Hurdle and colleagues at the Naval Research Laboratory, who speculate that the dinosaur hegemony may ended suddenly in flames rather than ...

They come in various shapes: droplets, buttons, even dumbbells. By general agreement, tekites are attributed to meteoric or cometary impacts that melt terrestrial rocks and splash liquid droplets into the atmosphere. There they are shaped by aerodynamic forces and solidify. This scenario is all very reasonable, but some nagging problems remain. Where-o -where is that crater? 770,000 years ago, a huge meteor hit somewhere on earth and strewed an immense batch of tektites and microtektites over fully 10% of our planet's surface (about 5 x 107 square kilometers). This is called the "Australasian strewn field." Such a recent cataclysm must have left a large and inescapable crater somewhere. The problem is that no one has yet found it. (Ref. 1) Many lines of evidence suggest that the missing crater is in Indochina. C.C . Schnetzler and J.F . McHone located four likely structures in Laos from Landsat images. However, visits to these areas found no evidence of an impact. (Ref. 2) So, this mystery persists. How were the Muong Nong tektites formed? Muong Nong tektites are unusually large (up to 24 kilograms), layered tektites. They are found in an area 1,000 kilometers in extent from Hainan Island to southern Indochina ...

This first sentence from a (sort of) disclaimer by the Editors of the American Scientist really seems unscientific. After all, Alfven shared a Nobel Prize in 1970; is that not recommendation enough? Apparently not -- at least not when Alfven believes that cosmic rays have a local rather than galactic origin. The reflections of Alfven on the development of cosmic-ray theory are rather amusing; they reveal how much people and ideas change. Alfven originally maintained that cosmic rays were of galactic origin. But when he met E. Teller, who favored a local origin (within the sun's domain), Alfven was swayed. He is now among that tiny minority that defends the local origin view. Ironically, Teller switched sides, too, and now espouses a galactic origin. Alfven concludes his reminiscing with a paragraph that says much about today's scientific environment: "The mentioned conditions and quite a few other factors have led to a disagreement between a very strong establishment (E ) and a small group of dissidents (D ) to which the present author belongs. This is nothing remarkable. What is more remarkable and regrettable is that it seems to be almost impossible to start a serious discussion between E and ...

Science Frontiers ONLINE No. 92: Mar-Apr 1994 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Did humans evolve in siberia?Russian academician Yuri Mochanov thinks so! He does not dispute that humans may also have evolved in Africa and, perhaps, Southeast Asia. And he has brought back some 4,000 stone tools collected at 15 sites in the Siberian permafrost to bolster his claim that Siberia, too, was a point of origin for hominids (see map). "Molchanov's controversial evidence is indeed striking: a collection of chipped and flaked rocks that are clearly artifacts fashioned by humanlike hands and that he contends are 2.5 million years old -- plus or minus a half-million years. "Remarkably, that same era marked the time when early human ancestors known as Homo habilis lived and left their remains in the tropical Olduvai Gorge of what is now Tanzania. Mochanov's collection of tools closely resembles the ones that anthropologists have long collected from digs in Africa." All this contrasts strongly with the dominant view of hominid evolution, which cites warm, verdant African forests and savannas as our most likely place of origin. Siberia, with its -50 winters and fleeting summers, hardly seems conducive to hominid speciation. Mochanov's rationale is that this severe climate actually stimulated ancient hominids to create tools, fashion warm clothing, and build winter shelters -- these Siberian hominids had to evolve or perish! In addition to the climate factor are two other problems: (1 ) The ...

Chatterjee, a paleontologist at Texas Technical University. Chatterjee was so certain that the fossils (two specimens exist) were primitive birds that he named the species Protoavis texensis (first bird from Texas). During the past five years, the scientific community has chafed while Chatterjee studied his finds and wrote them up. It seems that many paleontologists do not think that Proto-avis is really a bird at all, and Chatter jee has been slow in releasing details. But now his first paper has appeared in the Philosophical Transactions of the Royal Society . Result: Many doubts still remain about the status of Protoavis. A. Feduccia: "Calling this the original bird is irresponsible." (1 ) J.H . Ostrom: "Sad to say, for all its length, little support for the claim is to be found in this paper." (2 ) J. Gauthier: While some of the bones appear bird-like, they also look dinosaurian and could represent a new type of theropod dinosaur. (3 ) For his part, Chjatterjee asserts that Protoavis' skull has 23 features that are fundamentally bird-like, as are the forelimbs, the shoulders, and the hip girdle. "His reconstruction also shows a flexible neck, large brain, binocular vision, and, ...

In nature it sometimes occurs in long prisms of hexagonal cross section. In fact, ancient Micronesians quarried multiton basalt prisms to build their fantastic megalithic complex of 92 artificial islets at Nan Madol. (SF#45) The inhabitants of ancient Mesopotamia had no basalt quarries at hand. Indeed, building stone of any kind was exceedingly scarce. What the Mesopotamians of the second century B.C . did have in abundance was alluvial silt. From this unpromising material they were able to make their pottery, writing tablets, and art objects. However, for grinding grain and engineering structures they needed something harder and stronger. Their innovative solution was: artificial basalt made from silt. They simply melted the silt and let it cool slowly. Sounds simple, but three remarkable intellectual and technical advances were required: The Mesopotamians first had to recognize that silt could be melted. This could not have been obvious in 1000 BC. Next, they had to develop hightemperature (1 ,200 C) smelters that were much larger than those they used for metallurgical purposes. Finally, they had to discover that slow cooling was needed for the growth of large crystals in the cooling melt. (Of course, they had no microscopes to see the crystals. So, it had to have been something learned from experience.) That ...

Billions of stars are nothing to them. The megaparsec (3 ,528,000 light years) is but a hop, skip, and jump. A pressing question for these cosmologists searching for the really big picture is whether there is any order in the distribution of galaxies, galactic clusters, and superclusters. The scale of organization of the universe is of critical importance because it is a measure of state of the cosmos when hydrogen atoms first condensed from the seething sea of ions following the Big Bang. The prevailing expectation has been that galactic clusters and superclusters should be distributed at random; that is, no order prevails at that scale. Recent redshift measurements, however, hint more and more forcefully that the huge superclusters of galaxies are almost as neatly arranged as the atoms in a crystal. A recent paper in Nature by J. Einasto et al puts a number on the spacing of the superclusters: "Here, using a new compilation of available data on galaxy clusters, we present evidence for a quasi-regular three-dimensional network of rich superclusters and voids, with the regions of high density separated by "120 Mpc [megaparsecs]. If this reflects the distribution of all matter (luminous and dark), then there must exist some hitherto unknown process that produces regular structure on large scales."

Bear in mind when going down the list that most of these features would have been considered absurd only a decade or two ago. The earth's solid inner core, which "floats" inside the liquid core, is not spherical. Rather, it is anisotropic with its axis of symmetry aligned with the earth's axis of rotation. (Ref. 1 below) "The CMB (core-mantle boundary) is the most dramatic discontinuity in the earth's internal structure in terms of the physical and chemical properties as well as the time scale of the processes that take place on either side of it. Its shape, if different from that predicted by the hydrostatic equilibrium theory, may contain information important to our understanding of geodynamic processes in the mantle or the geomagnetic field generated in the outer core." (Ref. 1, and also item #7 below) The earth's magnetic field possesses four lobes which remain fixed relative to the earth's surface, as demonstrated by 300 years of data. These lobes do not drift westward like the general field. (Ref. 2) "Core-spot pairs" of magnetic intensity seem to move westward and poleward. In the southern hemisphere, they originate under ...
