... , stands an enigmatic array of stone blocks. It "looks" like a wall; a human-built wall. It also "looks" old; perhaps 2,000 years old according to some. Who built it? Passions are running high in New Zealand, where three hypotheses are being advanced: The wall was built some 2,000 years ago by the first settlers of New Zealand, the Waitahas, who were subsequently nearly exterminated by the Maoris, who arrived only 800 years ago. There are political problems with this theory, for the Maoris insist they are the original New Zealanders and therefore are due compensation for lands expropriated by later Europeans. The wall is merely what's left of a sawmill built only 50 or so years ago. The wall is simply a natural rock formation that has happened to split neatly into rectangular blocks -- like 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 ...

Benveniste is in the news again! The July 20 issue of Nature has a news item entitled emphatically "INSERM Closes the File." (INSERM is the French institute of health and medical research.) Two INSERM committees recommended that Benveniste cease his work on high dilutions; work that seems to support the principles of homeopathy. The directory-general of INSERM, P. Lazar, however, did not endorse these recommendations. Benveniste was asked to look for errors in his experiments that might account for his "unusual results." Without question Benveniste is under the gun and future funding in jeopady. (Coles, Peter; "INSERM Closes the File," Nature, 340:178, 1989.) The headline in Science's news item was less emphatic: "Benveniste Criticism Is Diluted." Here, Lazar is reported as saying that he did not want to stifle research on new ideas and that Benveniste had been treated badly by Nature. Benveniste has not remained silent. In Le Monde , he stated that the results he had published in Nature have now been confirmed by two French teams, two American teams, and one in the USSR.

Some scientists, however, propose that the iridium layer was instead deposited through widespread volcanic activity. The proponents of an astronomical mechanism should be heartened by a recent paper in Nature, by W.S . Wolbach et al. Here is their Abstract: "Cretaceous-Tertiary (K -T ) boundary clays from five sites in Europe and New Zealand are 102 -104 -fold enriched in elemental C (mainly soot), which is isotopically uniform and apparently comes from a single global fire. The soot layer coincides with the Ir layer, suggesting that the fire was triggered by meteorite impact and began before the ejecta had settled." The composition of the hydrocarbons in the sediments points to the earth's biomass (mainly surface vegetation) as the source of the soot. The total quantity of K-T soot is equivalent to that which would be produced by burning 10% of all present terrestrial plant material.

Discovered over a century ago, new facts are still coming to light today, as reviewed by D.E . Wirth in a recent issue of The Ancient American. The wall was originally almost completely buried. It attracted attention only because its course was marked on the surface by stones projecting from the ground every 25-30 feet over a gently curving arc about 1,000 feet long. One of these surface stones seemed to be inscribed with strange symbols. Excavations, supported at first by the Smithsonian Institution, revealed a 3-ply sandstone wall-like structure seemingly cemented together by a reddish mortar. Splitting the sandstone sheets revealed diagonal rows of markings like those illustrated. At first, both wall and inscriptions were proclaimed to be artificial. More recent studies by geologists point to natural origins for the wall, the mortar, and even the inscriptions themselves. The latter ...

... All Issues This Issue Sourcebook Project Sourcebook Subjects The "residue fallacy" does not apply to all residues!While preparing our latst catalog in the field of geology, have been struck by how slavishly some mainstream scientists worship the Residue Fallacy. Briefly, this "fallacy" states that a single type of discrepant observation should not be considered viable if it contradicts a large body of well-established, internally consistent observations. In geology, the Residue Fallacy is employed to dismiss the precursorless polonium halos found by R.V . Gentry, as well as some other radiometric discordances. These scientists seem to have forgotten about the anomalous advance of Mercury's perihelion and a few other obvious residues that ultimately stirred up revolutions in our thinking. Anyway, it is now satisfying to find the Editor of Nature, mainstream science's preeminent journal, acknowledging the value of anomalies. The stimulus in this case is the morethan-a -decade-old inability of astronomers and physicists to explain the missing solar neutrinos. Two new, more sophisticated, neutrino detectors have come on line, in Japan and the U.S ., and they have confirmed the results obtained in the huge vat of cleaning fluid in the Homestead Mine, in South Dakota. For some reason, everyone measures only about one-third the number of solar neutrinos expected. Either something is wrong with our model of the sun's (and other star's ) energy-producing mechanism or our knowledge of nuclear physics is faulty. Recently, the solarneutrino anomaly has been complicated by the fact that the Homestead ...

The quotation above heads a revealing discussion by F. Hoyle and N.C . Wickramasinghe as to why their conclusions about cosmic life have not been accepted by the scientific community. Stimulating this article was a statement by J. Maddox, Editor of Nature, to the effect that the labors of Hoyle and Wickramasinghe were not convincing very many scientists because they ". .. had become caught up in the eccentric doctrine of panspermiology, a doctrine for which there was said to be little or no evidence." Hoyle and Wickramasinghe deny their eccentricity and affirm that their ideas have been acquired through observation and the generally accepted methods of deductive science. Basically, Hoyle and Wickramasinghe maintain that evidence supports the concept of life originating, evolving, and being transported from place to place in outer space. We have published many of their results in past issues of SF and see no need to cover the same ground again. Rather, we wish to dwell on the scientific reception of their work.

Indeed, a commentary in Nature by C.A . Murray begins as follows: "Larsen and Grier, on page 230 of this issue [Ref. 2], show that two similarly charged polymer spheres suspended in water can attract each other when they are several diameters apart. This surprising result casts some light on a tricky theoretical many-body problem that has been swept under the rug for a century, and it has implications for colloids in nature and in industrial processes." (Ref. 1) Exactly what happens is not yet clear. This counter-intuitive phenomenon occurs in a many-body situation, where screening charges are established between the like-charged spheres. Although Coulomb's Law states that like charges repel one another, the presence of screening particles complicates the picture, as do the van der Waals dipole interactions. The microscopic situation may be murky, but there is no doubt on the macroscopic level that unexpected attractive forces are operating. For example, when sub-microscopic, electrically charged latex spheres are suspended in water, one would expect a homogeneous colloidal soup. Instead, the tiny, charged spheres pull themselves together in patchy, but ordered arrays. These metastable groupings of spheres are called "crystallites." Theorists are not certain what is going on.

Not only is this complexity persistent under the attack of the Second Law of Thermodynamics, but it seems to actually increase with time. Do formative or guiding principles exist that science does not take into account? The two articles have very different answers. The creative cosmos. "Most people accept without question that the physical world is coherent and harmonious. Yet according to the traditional scientific picture, the Universe is just a random collection of particles with blind forces acting upon them. There is, then a deep mystery as to how a seemingly directionless assembly of passive entities conspire to produce the elaborate structure and complex organisation found in nature." The author of this introductory paragraph, P. Davies, asks, as we all do, "What is the origin of this creative power?" In groping for an answer, he presents first a common example of "blind" organization: the hexagonal convection cells in a pan of heated water. Using for a stepping stone the cooperative action of atoms in a laser, he leaps to the development of an embryo from a single strand of DNA! All such systems are "open"; that is, energy can flow in and out. They are also nonlinear, which means that chaotic, unpredictable action ...

Somehow nature had concentrated enough uranium-235 in one place to start a chain reaction, with the attendant production of heat and radiation. Now U-235 is radioactive, and there is now much less around than in past geological eras. This has led some scientists to speculate that many more Okla phenomena may have flamed momentarily in earlier times, especially Precambrian days. The mutagenic radiation from such natural reactors could have been a major driving force in evolution. (Anonymous; "Natural Reactors Helped Evolution," New Scientist, 100:737, 1983.) Reference.

How fortunate it is that kangaroo pouches open at the top; otherwise, little kangaroos would be falling out all over the place. While some marsupials have pouches opening "up" or "forward" in quite a few others evolution got the directions for pouch manufacture reversed. The koala, the wombat, the thylacine, and the marsupial mole all have backward-opening pouches. Obviously, a forward-opening pouch on the mole would act like a dirt scoop, to the great inconvenience of any occupants. On the other quadrupeds, the backwardopening pouch may protect the young from branches and vegetation. (Marshall, Jeremy H.; "Directional Pouches," Nature, 309:300, 1984.) Comment.

Upper-class women (perhaps men, too) favored green, white, and black makeup. These cosmetic powders, dating from 2,000 B.C ., have been exceptionally well preserved in their original vials made of alabaster, ceramic, and wood. A team of French chemists led by P. Walter was not surprised when their analyses of these powders found crushed galena and cerussite (two ores of lead). However, they nearly dropped their test tubes when they also found chemical compounds that are extremely rare in nature; specifically, laurionite (PbOHCl) and phosgenite (Pb2 Cl2 CO3 ). In fact, these compounds are so rare naturally that the Egyptian powders must be artificial. P. Walter et al wrote: "Taken together, these results indicate that laurionite and phosgenite must have been synthesized in Ancient Egypt using wet chemistry. The Egyptians manufactured artificial leadbased compounds, and added them to the cosmetic product. The underlying chemical reactions are simple, but the whole process, including many repetitive operations, must have been quite difficult to achieve." It had been recognized earlier that the Egyptian chemists had used fire-based technology 500 years earlier (2 ,500 B.C .) to manufacture blue pigment.

The essay goes far beyond the happy flamingo. It is about unusual adaptations in nature, as illustrated by three inverted or partially inverted creatures. The flamingo is a filter-feeder that strains food out of the water with its bill while its head is upside-down. The flaming's bill and tongue are (and must be ) radically different from those of other birds to succeed in this strange behavior. One type of jellyfish, rather than swimming around with its pulsating bell on top, plunks itself upside-down on the bottom and uses its bell as a suction cup to anchor itself. It then shoots poisonous darts attached to strings of mucous at passing targets and reels them in. Some African catfish graze on algae on the undersides of water plants. They swim upside down all the time and display a reversed color scheme, being black on the bottom and light on top. Gould employs these three examples to argue that changes in animal behavior must have preceded the many changes in form, function, color, etc. that make upside down living profitable. In other words, the proto-flamingos tried feeding with their heads upside down; and it didn't work too well. But "nature" responded with a series of random biological changes ...

Sagan, in a major review article in Nature, see a two-fold problem: (1 ) identifying the source of the raw materials; and (2 ) identifying the source(s ) of energy required for the synthesis of complex organic chemicals. First, they point to the steady drizzle of tiny, organic-rich particles drifting down to earth from cometary debris. These particles, which even carry spacesynthesized amino acids down to the earth's surface, seem likely chemical precursors of life. However, the atmosphere is also a potential source of prebiotic chemicals -- providing energy sources are available. Chyba and Sagan suggest as sources: lightning, ultraviolet radiation, and the shock energy derived from meteorite/asteroid/comet impacts. Together these energy sources, especially ultraviolet light, might synthesize thousands of tons of complex organic compounds each year.

Their physical appearances, habits, vocations, health histories, and other factors are often eerily the same. For example, two female identical twins, who had never seen each other, each wore eight rings! The upshot of such investigations is that most of a person's characteristics are genetic in origin; that is, Nature dominates nurture. But what about identical twins who are remarkably different? They can, for instance, differ appreciably in size, intellect, and behavior. In such cases, does nurture dominate nature? No!

Vertical ordinate represents intensity; horizontal axis is frequency in intervals of 10 kilohertz. Time axis runs into the chart with 12-second intervals. Over the years, several large radio astronomy antennas have listened for "intelligent" radio signals from outer space. The acronym SETI is customarily applied to such searches; SETI standing for Search for Extraterrestrial Intelligence. There have been a few exciting false alarms during these listening periods, but most could be attributed to known natural radio sources or manmade interference. All in all, it has been rather disappointing to those who are sure someone else is out there. The major exception in the SETI record was the so-called "WOW" (like Egad!) signal picked up in 1977 by a radio telescope at Ohio State University, in Columbus. The bandwidth of the sig nal was narrower than those of most natural sources; there was also some evidence of periodic and drifting features.

When a recent photo of the "Face" taken by the Mars Global Surveyor (MGS) was published far and wide in the science press, we thought the matter had finally been settled. The photo showed a strange hill obviously sculpted by natural forces. No question about it; there was not a soupcon of artificiality. But it now seems that if you look at the "Face" at other lighting angles and process the same data in different ways, the "Face" reappears looking more artificial than ever. T. Van Flandern elaborates: The MGS spacecraft took a high resolution photo of the "Face on Mars" in April 1998. That image suffered from four handicaps: a low viewing angle; a low sun angle from the direction of under the "chin"; an almost complete lack of contrast; and enough cloudiness to scatter most of the light and eliminate shadows. To add to these difficult circumstances, JPL-MIPL [Jet Propulsion Laboratory-Mission Image Processing Laboratory] personnel, apparently judging that the controversy over artificiality would not be ended when the actual photo was released, processed the image through two filters having the effect of flattening and suppressing image details. This step is documented at a JPL web site. Here we ...

Happily, he didn't strike the match, because it may be that he has something.

He says he can even detect the motion of the earth through absolute space and time, contrary to most Michelson-Morley-type experiments.

Ir relates to one of the most controversial digs in the New World: Pedra Furada, in Brazil. "The view that man did not arrive on the American continent before the last glaciation has been supported by the fact that until now the known and dated archaeological sites have not been of very great antiquity. But now we report radiocarbon dates from a Brazilian site which establish that early man was living in South America at least 32,000 years ago. These new findings come from the large painted rock shelter of Boqueirao do Sitio da Pedra Furada, the walls and ceiling of which are decorated with a rich set of prehistoric paintings. We have excavated a sequence containing abundant lithic industry and well-structured hearths at all levels. Carbon-14 dates from charcoal establish a continuous chronology indicating human occupation from 6,160 130 to 32, 160 100 years BP. A date of 17,000 400 BP, obtained from charcoal found in a level with fragments of a pictograph fallen from the walls, testifies to the antiquity of rupestral art in the region of Brazil."

We begin with the notion of anthropic cosmology, in which the physical constants of the universe are identified as having just the "right" values to allow the existence of stars, planets, carbon compounds, and the other ingredients of human life. (Just why this state of affairs prevails is a question rarely addressed!) Adherents of anthropic cosmology hold that our "human-friendly" universe is just one of many universes populating a larger metauniverse. These "other" universes are thought to have different values of the fundamental physical constants (viz., the mass of the proton) and, in consequence, wildly different forms of life. In nonhuman universes, there could even be entities for which our word "life" is inadequate. The second idea is that of an oscillating universe. In this concept, universes expand just so far and then collapse back into the "singularities" (i .e ., black holes) from which they arose. Then, Phoenix-like, they bounce back and reexpand into new universes -- ones with slightly different physical constants. These rebounding universes are in a sense ...

Picking up the gauntlet, several more-conservative archeologists visited the Brazilian site and penned a blistering critique in Antiquity. (Ref. 1) Their major contention was that the 500+ supposedly human-made stone "artifacts" collected by Guidon's team are actually "geofacts"; that is, they were chipped and flaked naturally as rocks fell one upon the other from nearby cliffs. We discussed this problem in some detail in SF#105. Several other reservations about the Pedra Furada work are also offered in Ref. 1.

Chaotic systems are usually qualitatively predictable but not quantitatively predictable. We have no choice but to live with this chaos; it seems that that's the way the cosmos is constructed! However, it now seems that the situation is even worse than chaotic! Some systems, perhaps most systems, are also indeterminate, meaning that we cannot predict their qualitative behavior either. A simple example is the water swirling down the bathtub drain. This is not only chaotic but it has two qualitative final states: clockwise and counterclockwise. Regardless of which hemisphere you are in, you can change the direction of swirl with negligible effort. Each of the two final states of motion is still quanti tatively unpredictable. Systems that are more complex will possess many different final states, all chaotic. Can nature really be fundamentally chaotic as well as qualitatively uncertain? J.C . Sommerer and E. Ott have mathematically examined a relatively simple system consisting of a single particle moving in a force field, experiencing friction, and being periodically jolted. Besides settling into chaotic motion, this particle may also be forced away to infinity -- two radically different final states. The analysis revealed that for any ...

The solution may be provided by multiple cometary impacts.

Their music, and ours, may have been entrained in genes inherited from nonhominid ancestors that lived 60 million years ago, but which have been suppressed in primates until Neanderthals and modern humans came along. You may wonder where this argument is taking you. It goes back at least 60 million years to when the cetacea (whales and dolphins) split off from the evolutionary track leading to humans. It may even go back farther to when birds split away from the reptilian line. The music of birds and whales incorporate some of the complexity and sophistication of Beethoven's Fifth. The genes that have led to such musical talents may be ancient indeed, as speculated in the Science article under review.

Whale songs have lengths between those of a human ballad and a symphony movement, suggesting a similar attention span. Some whale songs are similar in structure to human compositions.

For naked mole rats to survive over the long term, a biological solution to the inbreeding problem had to be found. The response of the species to this threat is the occasional production of a "dispersive morph." The largest and most successful colonies produce -- somehow -- a larger-than-normal individual, almost always a male, that is fuelled with extra fat and possesses a yen to travel. He is disinclined to mate with the resident queen, preferring to leave the colony for amorous adventure elsewhere. Thus, intercolony gene flow is established.

Of course, the naked-mole-rat colony, even when thought of as a "superorganism," cannot perceive the future consequences of inbreeding.

During the following half-century, scientists have been studying this perplexing problem, but it has been the amateurs who have accumulated the bulk of the data. Over 100 reports exist where echoes of radio transmissions were received seconds later at the original transmitting station. Since light travels 186,000 miles per second, any simple radio-wave reflector would have to be well beyond the moon's orbit. A wide variety of natural phenomena (interplanetary matter) and even artificial devices (alien space probes) have been postulated to explain the long delays. Muldrew's article is first of all an excellent summary of the long and fascinating history of this effect. His bibliography is extensive and apparently nearly complete. Muldrew next examines the various ionospheric mechanisms that might cause long delays. The ionosphere is a complex structure with ducts in which radio signals can get trapped. Delays of a second or so might be due to such trapping but the longer delays require some other explanation. Muldrew favors a rather complex interaction between signals from separate transmitters that (theoretically at least) can create a long-lived electrostatic wave that travels in the ionosphere -- a sort of natural memory device. The coded signals could then be read out much later when the proper natural conditions developed. Delays of up to 40 seconds might be possible with this "ionospheric memory ...

Impey says, referring to Malin 1. 'This galaxy is far removed from our ideas of what a normal galaxy should look like. There could be more of these things that haven't been discovered yet.'" (Anonymous; "Massive, Dark Galaxy Found in Void," Astronomy, 15:75, September 1987.) The same discovery is dealt with, in a more technical way, in Nature. A revealing paragraph from the Nature article follows: "Although Malin 1 could be a unique case there is in fact a significant body of circumstantial evidence to suggest otherwise. Our present knowledge of the galaxy population is so biased by a single insidious selection effect that it is entirely possible that Malin 1 is just the first example of a class of such low-surface-brightness giant galaxies that forms a significant constituent of the universe." The "selection effect" mentioned is a consequence of the very bright sky that confronts astronomers. Astronomical interest and instrumentation have focussed on those astronomical objects that are bright. In truth, the universe may be full of "icebergs and crouching giants."

Duesberg is a molecular biologist at the University of California, Berkeley. He contends that the human immunodeficiency virus (HIV) is not the cause of AIDS and is, instead, a harmless "passenger" in the bodies of AIDS victims. Naturally, this stance is controversial, and just as naturally we have had cause to mention Duesberg before. Duesberg is back in the news again because his iconoclastic views were prominently featured in a TV documen tary entitled "The AIDS Catch" seen in Britain in June. The scientific community was furious, claiming that the documentary was one-sided and selective. Further, it was maintained that Duesberg's arguments have been completely refuted. Briefly, Duesberg believes that AIDS is not an infectious disease because: Too few T-lymphocytes in the peripheral blood are infected to cause the disease; HIV carriers without symptoms exist; and HIV in pure form doesn't seem to induce Aids in humans or animals. Rather, says Duesberg, AIDS is a collection of symptoms arising from such factors as the repeated use of intravenous drugs and malnutrition. Mainstream researchers think that Duesberg is wrong on (1 ); that (2 ) is irrevelant, since asymptomatic carriers of typhoid and cholera exist; and that (3 ) may be incorrect, since SIV (Simian Immunodeficiency Virus) does induce simian AIDS in monkeys.

Science Frontiers ONLINE No. 64: Jul-Aug 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Directed Mutation Dear reader, things have a way of working out serially. For several months, we have had in our possession a paper from Nature, by J. Cairns, of Harvard, plus some passionate correspondence stimulated by the paper. Now that the circle-forming sheep have provided a good introduction, we will jump into the fray, too. Basically Cairns (in Nature) and B. H. Hall (in Genetics ) say that organisms can respond to environmental stresses by reorganizing their genes in a purposeful way. Such "directed mutation" shifts the course of evolution in a nonrandom way. Such a conclusion was like waving a red flag in front of the evolutionists. R. May, at the University of Oxford, complained, "The work is so flawed, I am reluctant to comment." On the other side, a University of Maryland geneticust, S. Benson, comments, "Many people have had such observations, but they have problems getting them published." Our template in this discussion is an article by A.S . Moffat in American Scientist. She says, "The stakes in this dispute are high, indeed. If directed mutations are real, the explanations of evolutionary biology that depend on random events must be thrown out. This would have broad implications. For example, directed mutation would shatter the belief that organisms are related to some ancestor if they share traits. ...

... Science Frontiers ONLINE No. 12: Fall 1980 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Rehabilitation Of Cuvier Cuvier (1769-1832) was a catastrophist. To him, the record of death in the layers of fossiliferous rocks was obviously the consequence of terrestrial convulsions. But Cuvier's ideas were swept aside by the uniformitarians who saw the earth and its cargo of life unfolding with almost agonizing slowness. But Cuvier is making a comeback, as illustrated by the following back-to-back articles in Nature. We quote from the abstracts. "Closely spaced samples from an uninterupted calcareous pelagic sequence across the Cretaceous-Tertiary boundary reveal that the extinction of planktonic Foraminifera and nannofossils was abrupt without any previous warning in the sedimentary record, and that the moment of extinction was coupled with anomalous trace element enrichments, especially of iridium and osmium. The rarity of these two elements in the crust of the Earth indicates that an extraterrestrial source, such as the impact of a large meteorite may have provided the required amounts of iridium and osmium." (Smit, J., and Hertogen, J.; "An Extraterrestrial Event at the Cretaceous-Tertiary Boundary," Nature, 285:198, 1980.) "Evidence is presented indicating that the extinction, at the end of the Cretaceous, of large terrestrial animals was caused by atmospheric heating during a cometary impact and that the extinction of calcareous marine plankton was a consequence of poisoning by cyanide released by the fallen comet and of a catastrophic rise in calcitecompensation depth in ...

At this Pennsylvania site, the six deepest dates definitely associated with cultural material indicate that humans were here 13,955 to 14,555 years ago.

Bray recounts in Nature what happened at a meeting at the Smithsonian last September. Various controversial sites were discussed, such as Calico Hills (200,000 years claimed) and Toca de Esperanca, Brazil (3 ,000,000 years claimed). But, oddly enough, the Meadowcroft Rockshelter and Kansas River data were not mentioned. Chiefly, though, Bray was concerned with what did and what did not constitute generally acceptable proof in archeological dating. That this matter goes beyond idealized science is evident in Bray's quote of anthropologist E. Leach: "Justification in terms of scientific methodology is in part self-deception, for when the figures turn out wrong the true believer will always shuffle the figures; when contrary evidence shows up, he throws doubt upon the credentials of the investigator." ...

In the 1983 issue of Nature (303:522), J.A . Beardmore and F. Karimi-Booshehri reported that, based on a study of a specific British population, A-blood groups are significantly more common among the higher socio-economic groups. As one might predict whenever someone asserts that human success is genetically determined, an avalanche of mail descended on the Nature office. Two other studies that did not show the blueblood effect were offered, although somewhat different populations were involved. Many letters tried to find an explanation for this anomaly in the constitution of the sample. By the time one got to the response by the authors, the whole issue was clouded. (Mascle-Taylor, C.G .

... , at Laurentian University, Canada, have reported some advances in our understanding of this classical anomaly. The group discovered that they could make ordinary sand musical by repeated grinding, polishing, and removal of fines. Given sufficient processing, ordinary sand that is merely "noisy" when shaken can be made to "sing." Singing sand has a unique infrared signature: a broad band stretching from 3,700 to 2,800 cm-1 . This is probably due to clusters of water molecules in an amorphous silica layer on the surfaces of the sand grains. Taking a clue from the infrared spectrum, Goldsack et al shook commercially available silica gel in a bottle and heard the familiar tones of singing sand! Their conclusion is that for sand to sing the particles must be coated with naturally (or artificially) created silica gel. (Goldsack, Douglas E., et al; "Natural and Artificial 'Singing' Sands," Nature, 386:29, 1997. Also: Cohen, Philip; "Desert Dunes Sing Silica's Song," New Scientist, p. 17, March 8, 1997.) Comment.

... the planet, another strange creature, also classified with the mammals, frequents muddy waters looking for the same sort of prey favored by the star-nosed mole. The Australian platypus also has weak vision and employs search techniques similar to those of the mole. Instead of sensor-bearing tentacles on its prow, the platypus has a duck-like bill loaded with electrical sensors.
