Or maybe just an artifact of the spacecraft and ground-based equipment? The fact that four spacecraft feel its tugging suggests the force is real. But the motions of the distant planets do not seem to be affected by it. So, everyone is perplexed. (Schilling, Govert; "Spacecraft Motions Puzzle Astronomers," Science, 281:1581, 1998.

From an orthodox point of view, the most plausible explanation for this is quite surprising: many color forms as well as biological species developed over a period of less than two hundred years." This is certainly explosive speciation -- real biological punctuation! But, perhaps as water levels fell, the original cichlids found refuges in surviving pools and then repopulated the lake when the waters rose. But is it reasonable to believe that they all sorted themselves out so perfectly that many species are found nowhere else in the lake? The probability seems high that cichlid speciation has been very rapid -- too rapid, one would think for random mutation and the slow feedback of natural selection to accomplish this daunting task in just a century or two.

Lekson, from the University of Colorado, was surprised to find that three important Anasazi sites in the Southwest are actually aligned with high precision along Longitude 107 57'. The three sites are: Aztec Ruins and Chaco Canyon (New Mexico) and Casas Grandes (Mexico). Even though the first and last are separated by about 450 miles, all sites are within 1 kilometer (5 /8 of a mile) of the north-south line. Lekson maintains that an alignment this precise cannot have happened by chance. How could the Anasazi have achieved such an accurate alignment over such rugged terrain? It would not be easy even with modern transits. (Cohen, Philip; "One Dynasty to Rule Them All," New Scientist, p. 17, December 14, 1996.) Comment.

... the following sentence found in Nature: " The standard ideas of the 1980s about the shape and history of the Universe have now been abandoned -- and cosmologists are now taking seriously the possibility that the Universe is pervaded by some sort of vacuum energy, whose origin is not at all understood." Does this mean that the Big Bang, the mainstay of the astronomy we were taught in school, is now being cast aside? After all, the Big Bang does model fairly well three important observations: The apparent expansion of the universe; The 3 K microwave background; and The abundances of the light nuclei. But try as they may, cosmologists have not been able to coax the Big Bang model to explain the large-scale lumpiness and structure of the galaxies and galaxy clusters. One problem with the Big Bang is that it has too many free parameters -- too much theoretical slack. Many cosmologists are now looking for a better model. This better model, to use the words of P. Coles, should be more "exciting" and "stranger," something "perhaps not even based on General Relativity." (Coles, Peter; "The End of the Old Model Universe," Nature, 393:741, 1998.) Questions.

This particular wad came from a Swedish bog, but similar wads have been found all over Northern Europe. Not having access to South American chicle, ancient confectioners made the gum from birch bark. Birch bark was also the source of the tar primitive humans used for gluing and waterproofing. E. Aveling, University of Bradford, has concocted a fresh batch of birchbark gum for a taste test. (No one volunteered to try the "old" stuff!) She reported that it is neither pleasant nor unpleasant, but neither are modern-day Moxie and Vegamite.

... Online All Issues This Issue Sourcebook Project Sourcebook Subjects Archea: Tough And Different Today's textbooks recognize only two main divisions of life: the prokaryotes (cells without nuclei) and eukaryotes (cells with nuclei). Humans and most of the life forms we are familiar with belong to the latter group. (Curiously, human red blood cells lack nuclei!) However, a third basic type of life has been found prospering in some extreme environments. These are the Archea, typified by the methane-producing microbes discovered clustered around hot deepsea vents, where temperatures may exceed 400 C. It is not their rugged constitutions that place these miniscule forms of life in a new category; it is their genomes. They are radically different from those found in prokaryotes and eukaryotes. The genome of one species of Archea collected from a hot vent 3 kilometers deep in the Pacific has been sequenced. Biologists were taken aback. Methanococcus jannaschii , as it has been dubbed, possesses 1738 genes, of which 56% are entirely new to science. Many of these genes do not look anything like those found in the prokaryotes and eukaryotes. In a word, they seem "alien." (Morell, Virginia; "Life's Last Domain," Science, 273:1043, 1996.) How alien? Well, they are so tough that they could have arrived from Mars on a meteorite.

Acoustical pipes were also invented by close relatives of the beaked whales, the dolphins. With the dolphins, it is the lower jaw that has been converted into a "sound pipe" for receiving sonar echoes. Dugongs, too, possess squamosal bones filled with oil that are probably also connected with sound detection. Evolution has been highly innovative -- three times, in different ways -- in designing acoustical pipes in marine mammals! This is very impressive for a method that begins with a random process.

... before. (SF#84/279) We now have more precise data. Wave-height measurements at the Seven Stone Light Vessel, anchored in the northeastern Atlantic, show that wave heights have increased 2.4 centimeters/year during the period 1960-1985. This is not a trivial amount. At this rate, waves a century from now would be 2.4 meters (about 8 feet) higher. Many existing coastal structures will be smashed to bits. All this is over and above any effects from rising sea levels. The records from the Seven Stone Light Vessel are corroborated by an analysis of more then 20,000 wave charts of the North Atlantic drawn between 1960 and 1988. It therefore seems clear that something unusual is going on in the North Atlantic. One would suspect increased winds, but velocities measured at Seven Stone have remained constant while wave heights rose. It is concluded that the bigger waves are not generated by local winds; rather, they are swells that have been created thousands of miles away. The cause of these larger swells now affecting the entire North Atlantic is not known. The authors of this paper are forced to conclude with: "It should be noted that so far it has not been possible to attribute the observed change to either an anthropogenic cause or to natural climate variability on decadal time scales."

... attracted to them until clear-cutting of the trees in the 1970s made the size and novelty of Watson Break all too obvious. Just how anomalous is Watson Break? Archeologist V. Steponaitis, from the University of North Carolina, opined: "It's rare that archaeologists ever find something that so totally changes our picture of what happened in the past, as is true for this case." On what does Steponaitis base such a powerful statement? Watson Break is dated at 5,0005,400 BP (Before Present), some three millennia before the well-known Moundbuilders started piling up earthen structures from the Mississippi Valley to New York State. In other words, the site is anomalously early. Indications are that Watson Break was built by hunter-gatherers, but no one really knows much about them; there's an aura of mystery here. Watson Break consists of 11 mounds -- some as high as a two-story house -- connected by a peculiar circular ridge 280 meters in diameter. The back-breaking labor required to collect and pile up all this dirt is incompatible with the life style of mobile bands of hunter-gatherers. The purpose of the Watson Break complex escapes us. Why the mounds? Why the circular ridge? Can we just shrug it off as a "ritual site"? (Saunders, Joe W., et al; "A Mound Complex in Louisiana at 5400-5000 Years before the Present," Science, 277:1796.

... we have to wonder if there is not a cog railway or something similar to aid organisms as they ascend this Mount. Such thoughts arose when reading C. Koch's Nature article on neurons and their networks. Neurons are cells with three principal components: the cell body, the axons, and the dendrites. These cells and the networks underlie all of our perceptions, actions, and memories. The ways in which they store and process information has turned out to be much more complex and dynamic than previously supposed. Neural networks are so intricate that Koch was impelled to conclude his review of current research with this paragraph: "As always, we are left with a feeling of awe for the amazing complexity found in nature. Loops within loops across many temporal and spatial scales. And one has the distinct feeling that we have not yet revealed every layer of the onion. Computation can also be implemented biochemically -- raising the fascinating possibility that the elaborate regulatory network of proteins, second messengers and other signalling molecules in the neuron carry out specific computations not only at the cellular but also at the molecular level." (Koch, Christof; "Computation and the Single Neuron," Nature, 385:207, 1997.) Comment. Thus, Dawkins' Mount Improbable is seen to be even higher and more majestic.

That PEAR results are unaffected by by the timing and distance of the operator attempting to affect the behavior of the machine is somewhat troublesome to many scientists, but not inconsistent with some predictions of quantum mechanics. Much more serious to objective science is the implication that a scientist performing an experiment can subjectively (consciously or unconsciously) affect his results, as in the psychokinetic control of a meter reading or an electronic data processor.

The former are very happy in such extreme environments as the salty Dead Sea and the sea-bottom, hydrothermal vents; the latter prosper in bad hamburgers and your gut. Despite their differences, they have always been thought to have evolved from a common ancestor. A more subtle, fundamental difference has now been found. Recall SF#117 and how some terrestrial life forms do incorporate right-handed molecules in their structures, especially in cell membranes? The ubiquitous Eubacteria do this. In the Archaea, however, the same structural components of the cell membranes (glycerophosphates) are left-handed. A subtle difference, but one with deep implications. Some scientists maintain that it is impossible for two organisms relying upon mirror-image versions of the same molecule to have evolved from a common ancestor. Their genomes must be fundamentally different. Conclusion: the Archaea and Eubacteria must have evolved separately, and from different biological wellsprings -- that is, "creations." Such thinking is anathema. M. Kates, a Canadian evolutionary biologist, is skeptical.

There one finds good-sized rocks at the ends of long tracks they have made when some force has propelled them across the flat playa surface. What has moved these rocks, some of which weigh 700 pounds? The current consensus holds that wind is the motive force, but that it is inadequate to move the rocks directly. Instead, the wind acts upon sheets of ice in which the rocks are frozen. As these sheets of ice are moved across the playa, the keels of the frozen-in rocks leave those curious trails that have intrigued Forteans for many decades. (SF#109) Playa sliders have also been found at Magdalenasmeer Playa in South Africa, and in Nevada and Tunisia. In a recent issue of Geology Today, C.C .

... the analytical techniques and apparently avoided any taint of contamination. Their conclusion: the Murchison amino acids still lean to the left. From all this arise several intriguing possibilities: Life on earth started split evenly between left- and right-handed amino acids, but was nudged to the left by the influx of organic-laden meteorites like the Murchison. Terrestrial life actually originated elsewhere in the universe where much matter is left-handed, including life, if it exists there. In other words, our philosophical expectation of symmetry in the universe-as-a -whole is incorrect. The universe on the average is evenly split between left- and right-handed molecules, but there are "islands" or "pockets" which are left- or right-handed. Earth life is one of these "islands." Given the chance, amino acids and other organic molecules would exist evenly split, but physical phenomena, such as circularly polarized light, tip the scales -- to the left, in the case of terrestrial life. But that would mean that some physical phenomena are not symmetrical!

... 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.) Comments.

Sure, there are also a few creatures that derive their energy by oxidizing the sulfides dissolved in the 400 water gushing forth from deep-sea vents. We will call them "geochemical creatures" to separate them from the "photosynthetic creatures" we are more familiar with. But, in principle at least, there could also be "Carnot creatures", whose metabolisms depend upon temperature differences like almost all human-built engines. Some bizarre animal, such as a meter-long tube worm, could plant one end on a hot rock surface and dangle the other in cold seawater to reject waste heat from its Carnot engine. Since thermodynamic-cycle efficiencies can approach 60% compared with only 10% for photosynthesis, evolution would have been remiss if it had not tried to evolve "Carnot creatures." For, as D. Jones comments below, Carnot creatures would be adaptable to many more habitats in the universe than photosynthetic creatures, which must have a sun with a very specific electromagnetic spectrum.

Such professional testimony is usually dismissed as due to the reflection of greenish ground vegetation by the storm clouds or, perhaps, the effects of sheets of hail preceding the storms. In 1995, F.W . Gallagher et al decided to settle the matter. They chased likely looking thunderstorms armed with a spectrophotometer. Many storms later, they proved, first of all, that some thunderstorms are definitely green. In fact, some gradually change from blue to green in the space of half an hour. Their ground observations, plus more spectrophotometer data taken from aircraft, refute the theory that the green color is from reflected vegetation. Hail may contribute to the green color but is not required. In sum, green thunderstorms really do exist, but no one yet knows where all the green comes from.

... t the force of gravity modified the basic structure of the cosmos over the billions of years that followed the Big Bang? The astronomical quandry is this: If the very early universe looks pretty much the same as today's universe, the implication is that mass, the source of gravitational sculpting, is scarce. But this is at odds with the cosmic expansion rate which implies a much higher density of matter. (Appenzeller, Tim; "Ancient Galaxy Walls Go up; Will Theories Tumble Down?" Science, 276:36, 1997.) Comment. The existence of galaxy walls, like so many astronomical constructs, depends upon the assumption that the red shifts of galaxies are proportional to their recessional velocities and, additionally, their distances and ages. So much rides on this one assumption. The same situation prevails in biology, where everything is founded on the assumption that random mutations and natural selection can together generate any degree of complexity, sophistication, and innovation seen in nature.
