The biological phyla are defined by characteristic body plans. Humans, for example, are among the Chordata . Some other phyla are the Arthropoda (insects, crustaceans), the Mollusca (clams, squids), the Nemotada (roundworms), etc. All of these phyla trace their ancestries back to that biologically innovative period termed the Cambrian explosion. Even at the taxonomic level just below the phylum, the class (i .e ., the vertebrates), most biological invention seems to stem from the Cambrian. J.S . Levinton, in a long article in the November 1992 Scientific American, explores the enigma of the Cambrian explosion. Did some unknown evolutionary stimuli prevail 570 million years ago that made the Cambrian different from all periods that followed? Or, has something damped evolutionary creativity since then? Levinton holds that biological innovation has continued unabated at the species level since the Cambrian explosion, but that new body plans; that is, new phyla; have not evolved for hundreds of millions of years. Therefore, something special and very mysterious -- some highly creative ...

At the low end of the density spectrum, we now find that Pluto's moon, Charon, and some of Saturn's moons have very low densities (1 .2 -1 .4 ), meaning they are probably mostly water ice. Such density figures come from direct observation of these objects' volumes combined with mass estimates from their orbital dynamics.

... Of Matter Turns Up In Cosmic Rays "Japanese physicists claim to have found evidence of 'strange matter' in cosmic rays. Their detectors have recorded two separate events, each of which can be explained by the arrival of a particle with a charge 14 times as great as the charge on a proton, and a mass 170 times the proton's mass. No atomic nucleus -- made of protons and neutrons -- exists that matches this description, but these properties are precisely in the range predicted for so-called quark nuggets, which physicists believe may be made of a type of material dubbed strange matter." (Gribbin, John; "New Kind of Matter Turns Up in Cosmic Rays," New Scientist, p. 22, November 10, 1990.) The original report appeared in Physical Review Letters , 65:2094, 1990. In it, the Japanese scientists describe their balloon-borne equipment, proving that one does not need fancy spacecraft to make important discoveries. The key feature of the quark nugget is its very high mass-to-charge ratio. Where do quark nuggets come from? The theoreticians surmise that they may be created when neutron stars collide or, perhaps, they are left over from the hypothetical Big Bang.

... Can rocks from the surface of a major planet or satellite be launched into interplanetary space by natural processes? A few years ago the answer to this question would have been a resounding "no" from the experts on both volcanism and impact cratering, the only geological processes known to eject solid material at substantial velocities. Observation, however, has once again confounded expectation." In the snowy wastes of Antarctica, scientists have picked up meteorites that almost certainly came from the moon and Mars. And near St. Gallen, Switzerland, there was discovered a 22-centimeter block of Malm limestone that was apparently ejected from the Ries impact crater, almost 200 kilometers away, about 15 million years ago. We know all of these rocks are impact debris because they contain shatter cones indicating a violent origin. Not only did these bits of debris confound expectations, but their shatter cones implied shock-wave pressures far too low to achieve lunar and Martian escape velocities, or even the velocity necessary to propel that chunk of Malm limestone 200 kilometers. Something was wrong somewhere. It has turned out that shock-wave theory had been misapplied. It is not the pressure that is important in ejecting bits of debris from around the impact site, but rather it is the pressure gradient. Anomaly extirpated!

Lightning could be seen around the edges and inside the thunderhead. All cockpit lights were on and the instrument spotlight was full on, with the door open. I had just finished setting the power and fuel flows for each engine. As the ship approached the thunder-head, there was a noticeable drop in horsepower and the airplane lost from 180 mph airspeed to 168 mph, and continued to lose airspeed due to power loss as we approached the thunderhead...A few seconds before the lightning bolt hit the airplane all four engines were silent and the propellers were windmilling. Simultaneous with the flash of lightning, the engines surged with the original power...The Captain and I discussed the reason for all four engines cutting simultaneously prior to the lightning flash and could not explain it, except for the possibility of a magnetic potential around the cumulus affecting the primary or secondary circuits of all eight magnetos at the same time."

... a solid sphere with unit radius can be cut into five pieces in such a way that two of the pieces can be reassembled into one solid sphere with unit radius, while the other three pieces are reassembled into a second solid sphere with unit radius. These are the minimum numbers of pieces required to do the trick, but it can be repeated indefinitely." Impossible, you say? Can one sphere fragment and be reconstituted as two solid spheres of the same size? Regardless of what the math says, it cannot happen in the real world! Well, BTT actually does mirror just such a phenomenon found in particle physics: "The magical way in which a proton entering a metal target can produce a swarm of new copies of protons emerging from that target, each identical to the original, is precisely described by the BTT process of cutting spheres into pieces and reassembling them to make pairs of spheres." (Gribbin, John; "The Prescient Power of Mathematics," New Scientist, p. 14, January 22, 1994. Cr. P. Gunkel.) Comment. Would it be frivilous to ask that if protons can multiply thus (seemingly magically), why can't fish fall from the sky?

... Thus were born the first metazoans -- the multicellular species. The road was now open to the evolution of what we term "higher" life forms. But before really complex organisms could evolve, the selfish, aggressive characteristics inherited from the ancestral single-cell species had to be tamed. Unfortunately, some of the controls that evolved -- and which we have inherited -- do not always work. Conversely, they sometimes work too well. J.M . Saul has described how the appearance of cancer in complex multicellular organisms may be the consequence of the failure of biochemical controls evolved to curb cell aggression: "Such failure may be seen as reversion to ancestral cellular behavior, or as failure of a cell with a monocellular heritage to perform metazoan tasks for which it was not originally designed. In such instances, the resultant types of wild and indiscriminate proliferation and variation would resemble pathologies classified as 'cancer.'" Furthermore, Saul speculates, overcontrol could lead to autoimmune diseases: "Within the individual metazoan, excessive antiproliferation measures would have occasionally resulted in focussed attacks against specialized classes of "innocent" cells, producing pathologies describable as 'autoimmune.'"

... fundamental assumptions we base our model on that may be wrong." A leading Big-Bang basher in H. Arp, of whom we have written frequently in SF. We will therefore not pursue his sort of bashing any further here. It is sufficient to say that Arp's doubts about the red-shift/distance relationship continue to receive support through observations of the heavens and in the lab. The other Big-Bang basher featured in Scientific American is H. Alfven, a Nobel-Prize winner in physics. Alfven postulates a universe dominated by electromagnetic forces, which he believes to be more important in shaping the cosmos than gravitation. His electromagnetic theory disallows any universe smaller than 1/10 the diameter of our present universe, thus excluding the Big Bang's point origin. Electromagnetic forces can account for all types of galaxies without resorting to the infamous "missing mass." Alfven can even account for the cosmic microwave background. Furthermore, Alfven's theories are supported by observations of solar-system plasma and magnetic fields. NASA's T.E .

Favored hypotheses mesmerize some, despite contradictory data and cogent arguments. In this respect, much science verges on religion. The foregoing "kernel of real truth" was occasioned by letters written to Science News in response to B. Bower's article on the probability of human artifacts -- as old as 100,000 years -- having been found at the Calico site in California. (See SF#51.) First, J.G . Duvall, III, attacked Bower's article, asserting that the human origin of the Calico "artifacts" had long ago been shown to be untenable. For a reference, he cited an article by himself and W.T . Venner in the Journal of Field Archaeology. Duvall's major point was that the Calico "tools" did not resemble proven Paleoindian tools. Responding to Duvall, G.F . Carter first pointed out that the Duvall-Venner paper was "almost instantly shown to be erroneous" by L.W . Patterson in the pages of the very same journal. As for the differences in artifacts, Carter asked why one should expect 12,000-year-old Paleoindian artifacts to look like 200,000-year-old artifacts from an entirely different culture.

Calculations, too, support the notion that a large meteoric impact could propel bits of the Martian surface into space where, statistically speaking, a tiny fraction would be captured by the earth's gravitational field. Some of these would fall to earth; others would remain in orbit. Now, the reverse scenario has been investigated numerically. S.A . Phinney and colleagues at the University of Arizona have calculated what would happen to small chunks of the earth's crust if a large meteor impact excavated a 60milewide crater. "Phinney's group used a computer to calculate where 1,000 particles would go if ejected from Earth in random directions, moving about 2.5 kilometers per second faster than the minimum speed necessary to escape. Of the 1,000 hypothetical particles, 291 hit Venus and 165 returned to Earth; 20 went to Mercury, 17 to Mars, 14 to Jupiter and 1 to Saturn. Another 492 left the solar system completely, primarily due to gravitational close encounters with either Jupiter or Mercury that 'slingshot' them on their way."

... first mentioned in SF#39, where we introduced those optical flashes seen in Perseus. At last, the professional astronomers are taking more interest in this class of bright, unexplained flashes in the night sky. Those amateur astronomers, with their "primitive" instrumentation, have actually had a paper published in the highly technical Astrophysical Journal. Their abstract follows: "Between 1984 July and 1985 July, 24 bright flashes were detected visually near the Aries-Perseus border by eight different observers at a total of 12 sites across Canada. One flash was photographed, and another was seen by two observers at different locations. Their duration was usually less than 1 s. The estimated positions of 20 of the events and another seen in 1983 were close enough in the sky to suggest a common celestial origin." The brightest of the flashes was of magnitude -1 and lasted about 0.25 second. (Katz, Bill, et al; "Optical Flashes in Perseus," Astrophysical Journal, 307: L33, 1986.) Comment. Hurray for Katz and the cooperating amateurs in the U.S . and Canada. One can wade through a 10foot pile of the Astrophysical Journal and not find another paper based on naked-eye astronomy.

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.)

... A SUBMARINE ORGAN?Exactly two years ago, we reported on strange seismic signals detected by German geophysicists near Mount Semeru, in Java. These signals consisted of a fundamental tone and evenly spaced harmonics. Sometimes, the fundamental tone rose and fell. This "natural trombone" was thought to be a gas-filled subterranean cavity capped at the top by rock, with a pool of magma at the bottom. Volcanic vibrations resonated in this chamber. As the magma pool rose and fell, the fundamental tone changed. More recently, a network of seismic stations in French Polynesia has picked up more mysterious seismic signals. These differ from those in Java in that each fundamental tone is "pure"; that is, there are no harmonics. Dubbed "T -waves," the sounds originated from an active volcanic ridge in the South Pacific. Suspicion fell on one flat-topped volcano that rose to within 130 meters of the ocean surface. But, how could this peak generate such a pure tone? The theory is that the active volcano spews out a column of steam bubbles bounded at the bottom by the flat volcano and by the ocean at the top. Computer simulations proved that sound could resonate in a column of bubbles just as it does in an organ pipe. Since the height of the column remains fixed, so does the fundamental tone. Certainly harmonics are generated, too, but the bubbles damp out the higher frequencies, leaving a pure tone. (Schneider, David: "A Blue Note," Sci entific American , 277:18, August 1997 ...

The molecular biologists are a bit arrogant in their assertions.

The most interesting "unexpected pattern" is the gross asymmetry between the diversification of life in the Cambrian explosion (about 440 million years ago) and that following the great endPermian extinction (a little over 200 million years ago). Biological innovation was intense in both instances; both biological explosions burst upon a life-impoverished planet. Many niches were unoccupied. Even so, all existing (and many extinct) phyla arose during the Cambrian explosion and none followed the Permian extinction. ". .. why has this burst of evolutionary invention never again been equaled? Why, in subsequent periods of great evolutionary activity when countless species, genera, and families arose, have there been no new animal body plans produced, no new phyla?" Some evolutionists blame the asymmetry on the different "adaptive space" available in the two periods. "Adaptive space" was almost empty at the beginning of the Cambrian because multicellular organisms had only begun to evolve; whereas after the Permian extinction the surviving species still represented a diverse group with many adaptations.

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.)

... biotites must have been molten for a good deal longer than 138 days, thus destroying halos of short-lived isotopes. R.V . Gentry, a creationist, thinks that the polonium isotopes are primordial -- created by God some 6,000 years ago, in situ and without precursors. The rocks displaying the halos would, therefore, be among the oldest rocks on earth. What Wakefield does is exxamine the geology of some of the sites from which Gentry obtained his biotite samples. Basically, he finds that the supposedly primordial rocks are often just dikes and veins that were formed much later than the earth's oldest rocks. Wakefield comments, "This fact alone tells us that the rocks bearing Gentry's halos, even if instantly created, have no bearing on the origin and age of the earth." But does Gentry's "Tiny Mystery" vanish? Not at all -- unlike the Cheshire cat's grin. The polonium halos, seem ingly without detectable precursors, are still there. Wakefield states with all honesty, "Still, we must give Gentry his due. Nothing in geology fully explains the apparent occurrence of the polonium halos as described by Gentry. They do remain a minor mystery in the field of physics." Someone may eventually find an explanation in terms of quirkish chemical deposition or misidentification of the halos, but for now the "Tiny Mystery" survives! (Wakefield, J.

... Life: Act Ii The final issue of New Scientist for 1996 carried an article entitled "Death Knell for Martian Life." Was all that media hype for naught? What will NASA do now? Wait! Another putative Martian rock may save the day. Picked up in Antarctica in 1974, meteorite EETA 79001 weighs 7.9 kilograms and is superficially unimpressive. Inside, though, researchers I.P . Wright and C.T . Pillinger found a surprising quantity of organic compounds -- actually 1.5 parts per thousand by mass. This fraction is so large that terrestrial contamination seems remote. Furthermore, the organic component contains 4% more carbon-12 (relative to carbon-13) than the adjacent carbonate minerals. This is strong evidence that the organics had a biological origin. Similar tests on the media-hyped Martian meteorite ALH 84001 yielded the same carbon ratios. Pillinger remarked: "These results offer the strongest support yet for the hypothesis that life once existed on the planet." So far so good, but EETA 79001 conveys two additional facts -- both very tantalizing: (1 ) This meteorite was blasted off the Martian surface only about 500,000 years ago; and (2 ) It probably came from a different hemisphere than ALH 84001. From all this, a somewhat shaky conclusion: Life on Mars existed not only recently (and perhaps is still present) but was (or is) widespread on the planet!
