Other terrestrial animals are also asymmetrical in various ways. But on the molecular level, terrestrial biochemistry is all left-handed. As far as scientists can determine, only left-handed amino acids are incorporated into proteins. In nonlife (if such a state really exists), amino-acid molecules are right- and lefthanded in equal numbers -- as least this has been the theory up until now. Amino acids are found in substances we assume are non-life or of abiotic origin. In fact, amino acids are present in meteorites, often in substantial amounts. They are profuse in Australia's Murchison meteorite, a carbonaceous chondrite. However, analysis of the Murchison's amino acids indicates that there are slightly more (7 -9 %) left-handed than right-handed amino acids present. This extraterrestrial handedness is of great import to both cosmologists and biologists, because the carbonaceous chondrites are thought to have formed 4.5 billion years ago -- long before life on earth originated. Furthermore, some of the Murchison's amino acids have never been found in terrestrial life, and they are also slightly left-handed. For some unfathomed reason, chemical and biological evolution both tilt to the left! (Bada, Jeffrey L.; "Extraterrestrial Handedness?" Science, 275 ...

C.M . Cook and M.A . Persinger associate these visitations with the phenomenon of "sensed presence" or the awareness of an extrapersonal, incorporeal entity. Cook and Persinger assert first that the so-called "sense of self" is a construct of the brain's left hemisphere -- the side usually associated with language. Second, they hypothesize that a "sensed presence" (spirit, god, etc.) is really only a fleeting right-brain homologue of the left-brain "sense of self," something like a transient shortcircuit between brain hemispheres that probably travels along that interconnecting conduit called the "corpus callosum." Repairing to their laboratory at the Laurentian University, Cook and Persinger asked subjects to press a button when they felt a "mystical presence." Unbeknownst to the subjects, they were occasionally exposed to weak magnetic fields. More often than chance would allow, mystical presences (button pushes) correlated with applications of magnetic fields.

(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."

Illumination of these regions somehow encourages our pineal glands to release melatonin. D. Jones has suggested a more direct way in which light can reach the pineal gland -- through our ears! The pineal gland, which is believed to be the relic of the third eye that our distant reptilian ancestors possessed, is now buried deeply in our brains. But, it is possible that light could reach it through the ears by diffusing through the soft, translucent tissues that lead into our skulls. A commercial opportunity arises here. Jones notes first that melatonin is a mood enhancer and stimulant. We all have read how depressed far-northern peoples become during their long winter nights; and we know first-hand how exuberant we are on bright spring days. Why not, asks Jones, manufacture "earlights" mounted on headbands? These would direct red light (which diffuses better through tissue) into the ears and thence to the pineal gland. People could thereby be made cheerful and enthusiastic whatever the season, weather, or time of day. We could dispense with all those mood-enhancing pills.

Some small squid will use their sharp beaks or tentacle hooks to rip open the skin of females. They then insert spermatophores with their penises. In the giant squid, however, the male's penis is formidable, muscular, and almost a meter long. It is powerful enough to insert spermatophores directly under the skin of the females. The males are not always accurate, for males themselves are sometimes impregnated in this manner during the squids' deep-sea orgies.

In SF#115, we asked whether right-handed organic molecules can be found in any terrestrial life forms. E. Clark answered as follows: "D -amino acids [right-handed amino acids] do occur fairly often in bacterial cell walls and other microbial products such as antibiotics. When I was first introduced to this fact, I was intrigued and I wondered if the presence of D-amino acids in these large molecules might indicate that there was something special about the way they were synthesized -- perhaps, for example, that they essentially assembled themselves without the need of individual synthetic enzymes at each synthetic step." (Clark, Ed; personal communication, February 28, 1998.) Comment. So, right-handed molecules are not forbidden on earth, but we are still faced with that great preponderance of left-handed molecules.

Every bacterium and human is a cosmic statement. Shifting from the macroscopic to the microscopic (phenotype to genotype), we recall that all macroscopic "statements" are really expressions of DNA -- the genetic code. But when we examine DNA, we find that only about 3% of the DNA in human cells codes for protein manufacture. The remaining 97% is termed "nonsense" or "junk" DNA. But there may actually be sense in nonsense DNA. Statistical analysis of nonsense-DNA "words" (3 -8 bases long) reveals considerable redundancy. Long stretches of nonsense DNA are definitely not random. In fact, the structure of nonsense DNA resembles that of language. The coding or "sense" DNA, on the other hand, lacks this language structure. The implication is that coding and nonsense DNAs carry different kinds of messages. The former consists simply of blueprints; the latter is couched in a language that we have not yet learned to read. (Flan, Faye; "Hints of a Language in Junk DNA," Science, 266:1320, 1994.) Comment.

Many astronomers are equally disturbed by the recent discovery that all these fleeing stars and galaxies are not being reined in by the force of gravity. In fact, observations of distant supernovas indicate that this exodus of matter is actually speeding up. Some universal repulsive force, it seems, is operating on very large scales of distance. From an unknown somewhere energy is being added to all constituents of the cosmos. The universe is more than a cloud of debris flying away from the Big Bang's Ground Zero. Somewhere, perhaps beyond the ken of our primitive instruments, is a fount of energy of which we know nothing. All this is a serious challenge to our understanding of space, time, and matter. Cosmologists are now appealing to quantum mechanical "shimmers," to "X -matter," and to a property called "quintessence."

The latter is definitely real and consists of an immense, low-lying plain centered roughly on the planet's North Pole. The opposite face of Mars is occupied by rough, cratered highlands. This sharp, profound crustal dichotomy has been known for many years and has resisted explanation. In SF#113, T. Van Flandern advanced the theory that the rugged southern highlands are composed of the debris from an exploded planet which Mars once attended as a satellite. Be that as it may, there is something puzzling about the northern plains. We now have information from the Mars Global Surveyor (MGS), now orbitting the red planet, that the low-lying northern plains are much flatter than thought. For thousands of kilometers, they are smooth on a scale of hundreds of meters. This is flatter than the lava flows of the lunar maria; flatter than the smoothest central Sahara. These startling data come from the MGS's laser altimeter that can measure elevation of the terrain below it with 10meter accuracy averaged over the beam width of 150 meters.

Those favoring the "ancient astronaut" theory assure us that the Wandjina figures are those of alien visitors! The so-called Bradshaw paintings don't fit in the "alien" category but they are so interesting that we choose to reproduce one here. It raises three problems: (1 ) The slim, flowing human figures remind one more of the Tassili rock art found in Africa's Sahara rather than that of the Australian Aborigines; (2 ) The objects at the left are enigmatic and technical-looking; and (3 ) The symbols (? ) at the top are undeciphered. The article at hand from Antiquity does not attempt to interpret the Bradshaw art. Instead, it discusses the social factors that mold the interpretation of the Wandjina and Bradshaw paintings. When Europeans first saw these paintings they were certain that their "advanced style" was far beyond the capabilities of the Aborigines (colonial prejudice). They must, therefore, be the work of "preAborigines." Today's Aborigines will have none of this condescension. They were the original settlers of Australia, and as such they have bona fide land and title claims. Any recognition of "pre-Aborigines" would undercut these claims. (McNiven, Ian ...

One of our French readers has summarized some points made in this new book. "Michel Jouvet, a French specialist of dreams, asks the question: Why do cosmonauts never dream about space? Why do they dream only about the Earth? "According to psychologists, the 'day residue' in dreams is rather important. Half of all dreams allude to events of the preceding day; 89% allude to events of the last 120 days. The older the event, the lower the odds that it will reappear during the night. When people wear colored glasses, they begin very quickly to dream in the same color. People who make a complete change of life; for example, by travelling to a faraway place; do not begin to dream about this new place for weeks or months. A Bassari from Senegal, who was resident in Paris for two extended stays, was asked to write down his dreams. Surprisingly, 88% of his dreams occurred in Africa and only 6% in France. This experiment and others like it are discussed at length in the book, but explanations are lacking. Do we really understand anything about dreams?

In 1940, when Nazi armies were victorious everywhere, D.B . Parkinson was designing a carded potentiometer for civilian telephones. One night, he dreamed he was on the Continent close to an Allied artillery piece. The remarkable thing about this gun was that every shell it fired it nailed a German plane. Parkinson expanded on this part of his dream: "After three or four shots one of the men in the crew smiled at me and beckoned me to come closer to the gun. When I drew near he pointed to the exposed end of the left trunnion. Mounted there was the control potentiometer of my level recorder. There was no mistaking it. It was the identical item." Bell Lab engineers quickly saw how Parkinson's potentiometer could be applied to antiaircraft gun control. The M9 gun director was the practical result of Parkinson's dream. In one week in August of 1944, the M9's were credited with destroying 89 of 91 V-1 buzz bombs launched from the Antwerp area toward England.

Did photosynthesis evolve at the earth's surface or deep in the oceans near hydrothermal vents? Such questions are engendered by the strength of the mysterious glow that emanates from these deep-sea vents. It is at these cracks in the ocean floor that very hot, mineralladen water gushes forth, and where colonies of bizarre tube worms, blind shrimp, and hyperthermophilic (high temperature-loving) bacteria thrive. (For details, see SF#60 or p. 238 in Science Frontiers, the book) The first anomaly is the strength of the glow itself. It is not all thermal radiation emitted by the 350 C water spewing forth from the vents; in fact, it is 19 times more intense than expected from theory. Something else is contributing energy, but no one knows what it is so far. The unexpected intensity of the vent glows also asks some provocative questions of the biologists: Is the glow strong enough to sup port photosynthesis? Quite likely, seems to be the answer. Are life forms in the vicinity of the vents employing photosynthesis? We don't know yet, but some bacteria do photosynthesize. Might not life and perhaps photo synthesis, too, have originated at the vents rather than on the planet's surface?

The geomagnetic field, the sun, the stars, prominent landmarks, and even odors help guide them across the continents and open seas. But birds are considered highly evolved animals so their sophisticated navigational techniques are not especially surprising. Monarch butterflies, however, are mere insects, with tiny brains (navigation-data processors) and not much in the way of the environment sensors and internal clocks required for long-distance migration. Yet, some of these colorful insects manage to flutter up to 4,000 kilometers from the eastern U.S . and Canada to their wintering grounds in Mexico. How do they do this? S.M .

This feat requires not only the measurement of solar azimuth but also reference to an internal clock. Humans cannot do this without artificial instruments. Furthermore, even on cloudy days, migrating monarchs fly in the proper direction (generally south-southwest).

To illustrate, some fungi may be 1,000 years old and extend for 35 acres (15 hectares) and yet possess a single, still unmodified genome. In his review of A. Rayner's new book Degrees of Freedom: Living in Dynamic Boundaries , T. Wakeford writes: "So, like the World Wide Web, a fungal network is decentralized. There is no central region capable of exerting control over the rest of the network. Rayner's own work suggests that the growth patterns of fungal filaments are forged as much by the environment that they encounter as by their genes. He believes that epigenetics, the process whereby opportunities in an organism's surroundings dictate which genes are expressed, is the norm in microorganisms. Genetic determinism is thus turned on its head." (Wakeford, Tom; "We Are the Fungus," New Scientist, p. 49, May 10, 1997.) Comment.

And other colors, too! We touched on this subject over a decade ago. (SF#54) Then we described how the use of red plastic mulch greatly improves the yields of tomato plants. More recent research reveals that fruit quality and resistance to pests are also improved. How can this be? Plant leaves, it turns out, contain color sensors -- light-sensitive pigments similar to those it the human retina. Obviously, the plants do not "see," but the pigments provide environmental information. Here's the mechanism: plant leaves reflect infrared light well, so when a tomato plant's pigments detect a lot of infrared, the plant "thinks" that it may be crowded out by competing vegetation. The tomato plant responds aggressively by growing more rapidly. The red plastic mulch between the rows also reflects a lot of infrared light, and it thereby tricks the tomato plant into accelerating its growth.

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.

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.

When an archeologist finds the contents of ancient garbage dumps (" middens") fused into a glassy slag. he has to ponder a bit longer. First, a bit of background. Natural glasses can be created in several ways. Impact-heating by meteorites or asteroids probably fused the famous slabs of Libyan Desert Glass and also the Darwin glass found in Australia. More curious are the peculiar glassy clinkers of fused wood ash found in hollow snags in trees after intense forest fires. This is called "combustion metamorphism." Combustion metamorphism is also common where undergound coal seams have caught fire and burn for decades. Humans get into the act, too. The ancient Scots piled up trees around their rock forts and fused the stones together with fire. (Why they bothered is unknown.) However, a different sort of natural glass has been found in east-central Botswana. There, archeologists have found 5-inch-thick layers of glassy slag interleaved with ashy soil in ancient middens (garbage dumps). These middens are not associated with pottery kilns or iron smelting. It is hard to imagine what could have melted layers of garbage, including pottery, plant material, and other biomass. Analysis of the slag indicates that temperatures of 1155-1290 C were required to fuse the garbage. Open fires could ...

(ESP14 in Anomalies in Geology) But, common as these "sonorous" sands are, the exact mechanism of sound production remains a mystery. D.E Goldsack and colleagues, 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," ...

Lately, though, we have been reading that Alaskan killer whales have been snacking on those cute little sea otters. Much more devastating to the killerwhale image is an article in Natural History describing the vicious attack of a pack of killer whales on a pod of much larger sperm whales 70 miles off the California coast. To ward off the attack, nine sperm whales had formed a rosette, heads together, with their powerful tails splayed outwards towards the enemy. The killer whales circled the sperm whales ominously. Every so often, one would dash in and tear off a huge chunk of blubber. Eventually, all nine sperm whales floated dead or dying in an ocean of blood.

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."

Most of these flashes have a perfectly good explanation. The earth's atmosphere acts like a prism and disperses the light of the sun into a spectrum, and the last portion of this spectrum that one usually sees is green. Conditions have to be just right, though. A flat horizon and a layer of warm air are important. But even when conditions seem perfect, the green flash does not always appear, and all one sees is the red tip of the sun sinking out of sight. Even if the patient observer is rewarded by a green flash, he may really have been deceived, for there are "false" green flashes. A. Young, San Diego State University, reported at a recent meeting of the American Astronomical Society on a peculiar type of optical illusion that can afflict observers of the setting sun. It seems that the intense red light of the sun near the horizon can bleach the red-sensitive receptors in the retina so that an intent observer becomes temporarily color blind to red. When this happens, the observer sees the yellow part of the dispersed solar spectrum as being green (yellow minus red = green). The true green flash may never have appeared at all.

"My wife and I saw a puzzling sight in October 1994, in the Mekong River near Nongkhai, Thailand, during a full moon, in the evening. Lights appeared under the water for a few hundred metres along the Mekong River. They rose from the bottom of the river and floated to the surface, then shot like missiles into the sky and out of sight. They were the size of beach balls, and many flew out of the water every few minutes, surfacing about 10 metres apart. I am told that this happens every year at the same time. Locals say it is caused by a serpent releasing her eggs. Does anyone know of this phenomenon?" A. Pentecost answered. He noted first the similarity of the Mekong phenomenon to the will-o '- the-wisp or ignis fatuus. The usual explanation of ignis fatuus blames the spontaneous combustion of marsh gas. However, the Mekong lights are initially seen under the water where there would not be enough oxygen to support combustion. Pentecost suggested instead phosphorescent bacteria or the "cold flame" of phosphorus vapor which might form through diphosphane decomposition.

Greek pyramids! On Greek soil, at Hellenikon and Ligourio west of Athens in the Argolid region, are two limestone pyramids that are stylistically very much like those at Giza near Cairo. The big difference is size; the Greek pyramids are only the size of a large room compared to the Great Pyramid's height (with capstone) of almost 500 feet. When excavations were made around the Greek pyramids in the early 1900s, pottery fragments from the Fourth Century B.C . were found, and it was presumed that the pyramids were also constructed then; that is, about the time of Alexander the Great. Recent dating of crystals from internal surfaces of the limestone blocks using thermoluminescence puts the construction times back two millennia. The Hellenikon pyramid dates to 2730 B.C .; the Ligourio, to 2260 B.C . This means that the Greek pyramids were built in roughly the same time frame as the Egyptian pyramids. Why would the ancient Greeks want to build miniature pyramids?

Bahcall said of the discovery that the very early universe was already partitioned by colossal walls of galaxies hundreds of millions of light years long. That walls of galaxies exist is not a new idea, but finding that they existed shortly after the Big Bang is highly disconcerting to most astronomers. How did these walls form so early? Why hasn'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.

Theodolite measurements revealed a non-random distribution of the directions of lines attached to look-alike figures. The second test showed a physical relationship of present-day Andean plant and animal figures imagined as silhouettes in dark spots along the Milky Way to figure-lines pointing to the rising and/or setting of the same Andean figure 2000 years ago. In the third test, all other lines extending to the desert horizon from a figure center keyed into dark spots and bright stars along the Milky ...

Sheldrake challenged the world of science with his book Seven Experiments That Could Change the World . One of the experiments he proposed was the objective testing of the claims that pets can somehow sense when their absent owners have begun the trip homeward. An Austrian television company decided to take up Sheldrake's gauntlet. Their experimental subjects were P. Smart and her terrier Jaytee, both of Ramsbottom, England. Two film crews were dispatched to Ramsbottom; one to follow and film Smart, and the other, Jaytee's activities while Smart was away. Sure enough, at the moment Sharp and the shadowing TV crew decided to return, after an absence of a few hours, Jaytee ran to the porch and waited there until his mistress returned. Naturally, this proof of Jaytee's "strong and reliable" psychic ability received much attention in the media. Then, in 1995, Sheldrake invited R. Wiseman and M. Smith, at the University of Hertfordshire, to independently verify Jaytee's talent. After all, Austrian television companies have little scientific standing. Wiseman and Smith conducted four experiments in all based on a protocol designed to satisfy the inevitable scientific critics. For example, "success" had to be carefully defined, because Jaytee frequently ran out to the porch when other people, dogs, and cars went by the house, and sometimes for no obvious reason ...

Science Frontiers ONLINE No. 121: Jan-Feb 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects How Homeopathy Might Work Although some people swear to the efficacy of homeopathy's "remedies," skeptics have been fond of pointing out that these fluids are so dilute that no molecules of the active ingredients are likely to remain. Believers respond that the fluid remedies somehow retain the "essence" of the active ingredient. In effect, they maintain that water has a "memory." No wonder mainstream scientists scoff at homeopathy. But wait, perhaps water can have a memory! A Cal Tech chemist has put extremely dilute solutions under his electron microscope and found that some contain strange "ice" crystals, even though room temperature and pressure prevail. Called "IE crystals," they are produced through the action of ions. They are stable even at higher temperatures. Subsequently, an immunologist at the University of California at Los Angeles discovered that the IE crystals can stimulate parts of the immune system. Water containing these strange forms of ice show a hundred times more bioactivity than plain water. (Anonymous; "Homeopathy and IE Crystals," Spectrum , p. 18, November/ December 1998. Cr. E. Fegert) Comment. Of course, we want to see independent confirmations of the Cal Tech and UCLA work, but we hope they will be objective rather than the usual knee-jerk reactions to homeopathy. See SF#59 and SF#69 for past confrontations over homeopathy. From Science Frontiers # ...

That's quantum weirdness all right, but this weirdness can also produce effects we can see and hear. All you have to do is cool helium down to almost absolute zero. It will liquify but, unlike most other gases, it will not freeze. You are surprised at this, of course. Now, if you spin a bowl of this liquid helium around, you will be astounded. The liquid remains absolutely stationary in its spinning container -- no centrifugal effects, no friction with the contained wall, nada!. However, the strangest part comes when you: "Draw a cupful out of the bowl, suspend it a few centimeters above the remaining liquid, then stand back and rub your eyes -- the fluid in the cup will cheat common sense by pouring itself, drop by drop, back into the bowl. A drop climbs up the inside of the cup, then runs down the outside. When it falls, another begins climbing, and the magic continues until the cup is dry."

San Francisco. "The Pacific Mail steamer City of Panama , which sailed from this port on Jan. 21 for ports on the Central American coast, had a strange experience, news of which has just been received here by mail from Acapulco. "Through miles of sea covered thickly with masses of vegetation, tree trunks, and the carcasses of dead animals the steamer sailed, the debris at times being so thick that her progress was impeded. Some of the trees were five and six feet in diameter, and the dead animals were of all descriptions. The debris was encountered on Jan. 28 in latitude 16.58 north and longitude 100.29 west. "The officers of the vessel were unable to explain the strange condition, and when they arrived at Acapulco no light was thrown on the subject. It is supposed that the floating mass was cast up by some gigantic volcanic eruption on the Central American coast." (Anonymous; New York Times, February 14, 1905. Cr. M. Piechota.) Comment.

Science Frontiers ONLINE No. 119: Sep-Oct 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Cassowary, 1; Automobile, 0 Many birds are done in by fast-moving cars. The usual avian mode of retaliation involves defecation, especially on freshly washed and polished automobiles. On occasion, though, birds will use brute force. For example, keas (New Zealand parrots) consider it their duty to pry out the rubber gaskets around automobile windshields with their powerful bills. A cassowary can be even more forceful. Recently, a motorist near Cairns, Australia, was forced to stop by a sixfoot cassowary standing in the middle of the road. He edged the car forward slowly, but the huge bird stood its ground. Then, he blew his horn. Bad move! The cassowary objected by kicking the auto, pushing the radiator into the fan, which cut a hole in it. (Anonymous; "Feedback," New Scientist, p. 104, June 13, 1998.) Comment. The flightless cassowaries are armed with sharp toenails, with which they disembowel New Guinea natives who displease them. Besides disposing of obstreperous automobiles, cassowaries are said to catch fish by wading into streams, spreading out their wings, waiting, and then closing them on sheltering fish.

Science Frontiers ONLINE No. 118: Jul-Aug 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Song Of The Earth After a major earthquake, the entire earth quivers like a sphere of jelly suspended in space. Already a slightly oblate sphere, the planet becomes successively a bit more oblate, then a bit more prolate, as illustrated. The amplitudes of these deformations are small, just a centimeter or so after big quakes. The tone or frequency of the quivers is just a few millihertz, which translates to periods ranging from 3-54 minutes. We doubt that the telestomping elephants mentioned under BIOLOGY can detect these quiverings. That the earth does indeed "ring" is old news. Geophysicist A.E .H . Love mentioned the possibility in 1911. It is also recognized that large earthquakes can set the earth to ringing (" quivering" is better). What is news is the discovery by N. Suda et al that our planet rings even when no major quakes are occurring, and no one yet knows why. Suda et al write: "The observed "background" free oscillations represent some unknown dynamic process of Earth." Suda and his colleagues detected these oscillations using a superconducting gravimeter, which they installed in a seismically-quiet place: Antarctica. The favorite explanation for the background oscillations is turbulence in the earth's atmosphere. Ocean tides and currents are also on the list as potential "bell-ringers." [El Ninos were not mentioned!] (Suda, Naoki ...

One of these is the so-called "stealth" region. For some 2,000 kilometers along the Martian equator west of Arsia Mons and Pavonis Mons stretches an area that is invisible to terrestrial radar. Of course, we can see this region; but, when a 3centimeter radar is pointed at it, no detectable echoes are returned. Thus, the term "stealth," as in the F-117 Stealth aircraft, Are the clever Martians trying to conceal something from prying earthlings, using, say, a "cloaking" device a la Star Trek? Of course not. Loose, unconsolidated sediments are poor reflectors of radar waves. Examination of Viking-Orbiter photos tell geologists that the "stealth" region is almost certainly thickly strewn with volcanic ash, which would absorb the radar waves very well.
