Science Frontiers ONLINE No. 127: Jan-Feb 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Ants Like Microwaves Back in 1990, an item in SF was titled "Ants Like Amps." (SF#60/160) The subject then was the strange mesmerizing effect electrical equipment has on ants. They dote on airport runway lights, household electrical meters, and in particular electrical relays, where they congregate en masse. Now, a decade later, we discover that they are also not adverse to exploring microwave ovens -- even when they are turned on! We cannot explain the attraction of electrical relays, but we do know how ants survive in humming microwave ovens. It is because the microwaves inside the oven form standing waves. Energy is high in some areas -- ants would fry there -- and weak elsewhere. Ants seem to be able to find these lowenergy refuges and survive very nicely -- perhaps on the food you were planning to consume! (Anonymous; "Them!" New Scientist, p. 109, July 31, 1999. Comment.

... this wild region were evidently inspired to develop throat-singing so that they could better mimic the sounds they heard in nature: the singing of birds, the wind, the sounds of insects. Throat-songs have two components. The first is at a low, sustained fundamental pitch, which can be likened to the drone of a bagpipe. The second, superimposed on the low drone, is a succession of flute-like sounds that resonates high above the drone. It is the second component that can be controlled so as to mirror natural sounds. The result is like nothing Mozart or Verdi conceived. But it is an art form valued in Tuva and a talent rather remarkable from a biologist's perspective. One should compare the vocal tract to an organ pipe with its standing waves, except that the human pipe is only 7 inches long in the average adult male. One end of the human pipe is the mouth; the other is at the so-called "vocal folds" deep in the throat (larynx). To control their "instrument" throat-singers move their tongues back and forth to change the standing waves in the vocal tract. The source of raw sound is the vocal folds. It is the vocal tract that shapes the raw sound into musical tones. Biofeedback is also involved as the throatsingers tweak the rate and manner in which the vocal folds open and close.

(SF#113) But if you want to surf some true Pacific giants, you must leave the shoreline and head for Cortes Bank 160 miles offshore. There, far out of sight of land, lurks a shallow rock shelf that amplifies wind-driven waves---but only the largest of them. The elliptical swirls of the smaller waves do not reach down to the rock shelf and are unaffected. But when bigger swells encounter the shelf they are amplified into giants. So challenging are these waves that. when conditions are right, expert surfers boat out to Cortes Bank and wait for the really big ones. Mike Parsons caught the first wave at dawn. It was 18 metres tall and moving at around 40 knots. You can't paddle fast enough to get onto a wave like that---you have to be towed by a jet ski.

A new BBC documentary entitled Ancient Voices proclaims that the first settlers of the New World were from Australia and Melanesia. Skulls thought to be 9,000-12,000 years old have been unearthed in Brazil with features that closely match those of Australians living about 60,000 years ago. Evidence of even earlier contacts comes from stone tools and charcoal at Serra da Capivara, in northeastern Brazil. These artifacts indicate human habitation as long as 50,000 years ago. These very early Australians, however, seem to have been exterminated by a later wave of Mongoloid invaders. W. Neves, University of Sao Paolo, has measured hundreds of skulls between 7,000 and 9,000 years old. He notes a marked change in skull shape during that period going from exclusively Australian to totally Mongoloid. (Anonymous; BBC Online Network , August 26, 1999. Cr. M. Colpitts. Comments The claimed Mongoloid invasion of Brazil jibes nicely with claims of early Chinese visits to the New World. The artifacts at Serra da Capivara support the findings of N.

An unusual rock fall at Yosemite created a similar air blast with severe consequences. July 10, 1996. Yosemite National Park, California. We reported this remarkable event in SF#111 for its far-flung seismic waves, which jostled seismographs at Berkeley and Reno over 200 kilometers distant. Actually, there were two rock falls 14 seconds apart. The "rocks" fell from a 665-meter cliff at Happy Isles in the eastern part of Yosemite Valley. No pebbles these; with volumes of 23,000 and 38,000 cubic meters. Although the impact area of the rock falls was not particularly large, the falls generated an air blast and an abrasive sandy cloud that devastated a larger area downslope of the impact sites toward the Happy Isles Nature Center. Immediately downslope of the impacts, the air blast had velocities exceeding 110 m/s [about 245 mph] and toppled or snapped about 1000 trees. Even at distances of 0.5 km from impact, wind velociies snapped or toppled large trees, causing one fatality and several serious injuries beyond the Happy Isles Nature Center. A dense sandy cloud trailed the air blast and abraded fallen trunks and trees left standing. (Wieczorek, Gerald F. et al; "Unusual July 10, 1996, ...

... of genetics and molecular medicine at Emory University and a champion of the African Eve theory. Surely an unusual illustration for the archeology section, but the DNA in these mitochondria may upset long-held theories of human migration. Anyway, Wallace has been studying mitochondria, those little energizers in human and animal cells. Strangely, mitochondria have their own DNA, which is separate and distinct from the nuclear DNA that directs other biological processes. Mitochondrial DNA has had its own history of evolution and is different for various human populations. Wallace has used this fact to trace the origins of American Indians by comparing their mitochondrial DNA with that from Asians, Africans, etc. His conclusions are controversial to say the least. The Amerinds, who comprise most of the Native Americans, arrived in a single migratory wave 20,000-40,000 years ago -- not merely 12,000 years ago! Native Siberians lack a peculiar mutation of mitochondrial DNA that appeared in the Amerinds 6,000-10,000 years ago, casting doubt on the Siberian land bridge theory. Instead, this particular mutation is found in Southeast Asia, Melanesia, and Polynesia. The Navajos, Apaches, and other so-called Na-Dene peoples entered North America a mere 5,000-10,000 years ago.

A seiche (pronounced "saysh") is a rhythmic rocking motion of a body of water that has been disturbed by natural forces, such as sudden weather changes and, especially, earthquakes. A famous example of the latter seichedriving force occurred on March 27, 1964, when the Great Alaskan Earthquake sent seismic waves rippling around the globe. Fourteen minutes after this quake, the tremors reached the U.S . Gulf coast and triggered numerous seiches in bays, harbors, canals, bayous, etc. Some crest-to-trough waterlevel oscillations reached 2 meters in amplitude. Startling though these seiches were to Gulf fishermen, most seiches are wellexplained. Bodies of water that are mostly enclosed have natural frequencies of oscillation or "sloshing," just as do coffee cups and bathtubs. The Alaskan quake just operated on a larger scale than a bump to your coffee cup! Short-period oscillations in the tidal record from Puerto Princesa, Palawan Island, Philippines. These are coastal seiches, but hardly "death waves"! So far, so good. But there are exists an interesting -- and sometimes dangerous -- class of related events that affects open coastal waters.

By suddenly shoving the surface upwards by about 40 centimeters, the quake generated atmospheric disturbances that spread skyward at velocities of 1,000-2 ,200 kilometers/hour. Upon reaching the ionosphere, the waves created ripples that were detected by the array of navigational satellites that make up the Global Positioning System (GPS). (Monastersky, Richard; "Bouncing an Earthquake off the Sky," Science News, 146:415, 1994) Comment.

... sunswept lagoons into the superficially featureless Pacific. How did these peoples, a thousand years ago, sail reliably from one speck of land to another, thousands of miles distant? The archeology of Oceania confirms that the Polynesians made such voyages centuries before they learned about compasses and navigation satellites. But were these voyages anomalous; that is, did the Pacific peoples possess devices or talents unrecognized today by mainstream science? For the most part, the answer seems to be NO. While the navigational abilities of the Polynesian seafarers seemed supernatural to early European explorers, it has been convincingly demonstrated -- through modern voyages -- that the senses of sight, hearing, smell, touch, and time-passage are and were sufficient for most interisland voyages. The early Pacific navigators were adept at observing the waves, stars, birds, clouds, winds, and several other natural phenomena that carry subtle directional cues. There are, however, modern instances in which Pacific navigators bereft of the usual sensory cues seem to employ an anomalous "sense." B. Finney, in his study of the possibility of human magnetoreception, tells how one native Hawaiian navigator, though wellschooled in traditional Polynesian navigational techniques, conquered the dread doldrums on a 3,000mile voyage from Hawaii to Tahiti in a way we might call "psychic.". In the doldrums, the sky is often overcast and the seas leaden, expunging the usual cues. This particular navigator, Nainoa Thompson, entered the doldrums on a black night, with 100% cloud cover. The wind was switching around and the waves cueless ...

The transit time difference is 2-4 seconds. Apparently, the earth's core is not perfectly spherical or its properties are different in different directions. The natural vibration or "ringing" frequencies of the earth are "split," that is, instead of a series of single "tones" we detect a series of closely paired frequencies. This is symptomatic of a core that is anisotropic; that is, its properties are different in different directions. J. Tromp, of Harvard, may have de-anomalized both sets of observations with a single theory: "For the shape of the core alone to explain the observations, he says, the shape of the inner core would have to be very unrealistic. Instead, he claims that the inner core behaves like a giant asymmetric crystal, aligned with the Earth's axis so that seismic waves travel faster in that direction. Tromp's analysis fits neatly with suggestions that the inner core is made of a high-pressure phase of iron in which the atoms are close-packed in hexagons, because such a 'sigma' phase is anisotropic."

This turns out to be far from the truth. For example, non-musicians use both hemispheres in musical matters; the right side for recognizing melody and intonation, the left for such analytical matters as rhythm and notation. However, professional musicians, as their brain waves demonstrate, use their left hemispheres for just about everything of a musical nature. So much for the right-hemisphere theory! The comparison of magnetic resonance images of 27 right-handed musicians and 27 right-handed nonmusicians have shown that even their brain structures differ. The corpus callosum -- that inter-hemisphere information highway -- is 10-15% thicker in musicians who began their training while young than it is in nonmusicians. Our brain structure is apparently strongly molded by early training. The corpus callosum in musicians is essential in such things as finger coordination. Like a weight-lifter's biceps, it enlarges to accommodate the increased tasks assigned to it. (Anonymous; "Music of the Hemispheres," Discover, 15:15, March 1994.) Comment.

Huge bulges hundreds of feet high and hundreds of miles in extent appear when satellite radar altimeter data are plotted. Equally large depressions in the ocean surface also show up -- none obvious to surface observers. This unexpected macrostructure of the ocean surface is shaped by variations in the strength of the earth's gravitational field and sea-bottom terrain.

Their recordings revealed a series of evenly spaced harmonic frequencies. They likened it to a musical instrument emitting a fundamental note accompanied by overtones. Sometimes, the fundamental tone would rise and fall, as if the mountain were playing a tune for them. The Germans, V. Schlindwein et al, postulated that the vibrations originated in a gas-filled cavity, presumably cylindrical -- something like an organ pipe -- capped at the top, with a pool of molten magma at the bottom. Volcanic vibrations resonated in this chamber and, as the magma pool rose and fell, so did the fundamental tone. Rather than a fixed organ pipe, it was a natural trombone! Unfortunately, the "earth music" was always in the infrasound range, 8 Hertz and less, and could not be heard by the researchers directly -- only their instruments could "listen."

... , 1994, what may be the largest deep earthquake of the century -- magnitude 8.2 -- exploded 640 kilometers beneath Bolivia. "Exploded" may or may not be the proper word. Geophysicists are really not certain what causes the very deep quakes, because at 640 kilometers rocks are so hot that they flow rather than snap under geological stresses. The more common, shallow earthquakes are generally created when rocks snap and fracture. Since the deep quakes seem to be concentrated in subducted slabs of terrestrial crust that plunge down deep into the earth's mantle, geophysicists suppose that the increasing heat and pressure applied to the descending slabs may cause "explosive" phase changes in minerals contained in the slabs. Phase changes often involve volume changes that, if sudden, might generate seismic waves. Too, water of hydration in minerals may be explosively turned into vapor. But this is all surmise at present. The Bolivian quake also caused the whole earth to ring like a bell. Every 20 minutes or so, the entire planet expanded and contracted a minute but detectable amount. Another surprise: the Bolivian earthquake was felt a far away as Seattle -- the first time that a quake in that part of South America has been actually felt in North America.

Where a cell or group of cells is permanently turned on, there is a dark stripe of pigment, and where the cells are dormant, there is an unpigmented space. The complementary pattern -- horizontal stripes, parallel to the growing edge -- results from a temporal rather than a spatial oscillation. All the secretory cells turn off and on in synchrony, so that light and dark bands are left behind on the surface of the shell as the growing edge moves on."

The oceans, however, also move in ponderous cycles that beachcombers can never appreciate. Thanks to data from Geosat's precision altimeter, geophysicists can now discern some of these long-period moving patterns on the oceans' surfaces. "Energetic 90-day oscillations of sea levels have been intermittently observed at Wake Island in the western tropical Pacific during the past 2 decades. The oscillations tend to occur about 1.5 years after El NinoSouthern Oscillation events, to have amplitudes of 10-15 cm, and to persist for about 1 year. Sea-surface heights from the Geosat altimeter are used to establish that these signals take the form of Rossby waves and have an energy source near the Big Island of Hawaii, which lies 40 of longitude to the east. Sea-level and upper-layer currents from an eddy-resolving numerical model are examined and suggest that the energy source is eddies generated off the Big Island of Hawaii.

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."

"the big crack"Huge chunks of the Hawaiian Islands have been sliding into the Pacific Ocean for hundreds of thousands of years. (SF#101) Geologists classify these slides as either "slumps" or "debris avalanches." Slumps move just a few inches a year but are prone to bigger, jerky adjustments. Debris avalanches are fast cascades of rocks and soil. In Hawaii, both varieties of movement can involve massive blocks of real estate. In the huge Nu'uanu debris slide, stone blocks 6 miles across tumbled 30 miles out to sea. Both slumps and debris slides may create colossal tsunamis. (Tsunamis are miscalled "tidal waves," but they have nothing to do with tides and do not behave like tides or wind-driven waves.) When large pieces of the Hawaiian Islands slip into the ocean, the entire Pacific Rim is smashed by the resulting tsunamis. In New South Wales, Australia, there is geological evidence that part of this coast was scoured by a Hawaiigenerated tsunami 100,000 years ago. The postulated wave started out about 375-meters ( -mile) high in Hawaii. By the time is reached Australia, it was about 40 meters high. (SF#85) Worse waves may be on tap. A 4,760 cubic mile chunk of the Big Island (Hawaii) is breaking away at the rate of 4 inches per year. This is the Hilina Slump, ...
