This is very close to the rotation period of Saturn's magnetic field. Somehow, the rotating magnetic field interacts with the particles making up the rings, forcing density or reflectivity changes that we see as transitory spokes. It is not yet clear how this magnetic tune is played. (Proco, C.C ., and Danielson, G.E .; "The Periodic Variation of Spokes in Saturn's Rings," Eos, 63:156, 1982.) Comment. Brightness changes have also been noted in the zodiacal light, which is light reflected from particles surrounding the sun. After reading about Saturn's variable spokes, one wonders whether solar-system magnetic fields might be the cause of these mysterious variations in the zodiacal light.

Inorganic magnetite precipitated from molten rock is octahedral, while the particles manufactured by bacteria are cubes, hexagonal prisms, or noncrystalline teardrops. The magnetite found in marine sediments appears to be organically formed -- at least the shapes of the particles are characteristic of bacterial manufacture. Apparently these industrious bacteria have been busy producing magnetite ever since "lowly" life forms appeared in the Precambrian. These facts pose at least four questions: How much of the earth's iron ore has been concentrated biologically and is there a connection with the Gaia Hypothesis? Is it possible that magnetic field reversals, now believed to be of purely geophysical origin, might be biological artifacts (that is, due to population and/ or species changes of magnetic bacteria)? If magnetic field reversals are of geophysical origin, how do the magnetic bacteria find their food sources during the long periods of near-zero field? Lab experiments prove that magnetic bacteria require free oxygen to secrete magnetite, but the Precambrian atmosphere and oceans were supposedly devoid of oxygen until 2.3 billion years ago. How did the magnetic bacteria prosper before then? (Simon, C.; "Tiniest Fossils May Record Magnetic Field," Science News, 124:308, 1983.)

The concentration of bacteriophages in natural unpolluted waters is in general believed to be low, and they have therefore been considered ecologically unimportant. Using a new method for quantitative enumeration, we have found up to 2.5 x 108 virus particles per millilitre in natural waters. These concentrations indicate that virus infection may be an important factor in the ecological control of planktonic microorganisms, and that viruses might mediate genetic exchange among bacteria in natural aquatic environments."

First, it suggests that bacteria in natural waters are probably kept in check by viruses as well as protozoans. So far, this sounds good. Second, since viruses can ferry genetic material between organisms via transduction (i .e ., host DNA is carried to the next host).

... , University of California at Riverside, has shown theoretically that in a five-dimensional world (4 of space, 1 of time) electric charge need not be conserved. This opens up an experimental avenue to test for an extra spatial dimension. For background, recall that physicists originally maintained that mass and energy had to be conserved separately. Then, Einstein came along to show that mass and energy could be interchanged, via E = mc2 , but that they had to be conserved together. In Shu-Yuan Chu's five-dimensional universe mass and charge can be interchanged, but their sum must be conserved. In other words, there exists an E = mc2 equivalent for mass and charge in five dimensions. We could look for this extra spatial dimension by looking for a particle that can be converted into another particle with the same mass+ charge, but made up of a different combination of mass and charge. If such reactions exist, we may be able to explore hyperspace in fact rather than in science fiction. (Gribbin, John; "Can Electric Charge Be Destroyed?" New Scientist, p. 16, October 5,1994.)

... , hard-to-visualize phenomena that are so scientifically important that it is worthwhile trying to understand them. In the first abstruse phenomenon, quantum mechanical effects demonstrate that the laws of classical electromagnetism are flawed. According to the classical view, an electron cruising by an ideal solenoid (a tube with an internal magnetic field but none outside) should be unaffected; that is, the electron should not "feel" the confined magnetic field. But, in the quantum mechanical view, the "presence" of the electron is smeared out so that it penetrates the solenoid, and the electron is affected by the confined field. This has been demonstrated. A Los Alamos scientist, D. Ahluwalia, ventures that an analogous situation prevails with gravity. He notes that General Relativity predicts that a particle (or person) in free fall cannot distinguish this condition (weightlessness) from the situation in a hollow shell of matter, where the gravitational field is cancelled out. A person would feel weightless in both situations. But the strange part arises when one looks at the two situations from the perspective of quantum mechanics; that is, one puts gravity into Shroedinger's equation. Ahluwalia asserts that the particle's (or person's ) gravitational presence is smeared out, just like that of the electron outside the solenoid. In consequence, masses can "feel" their gravitational potential and will behave differently in free fall than when inside a hollow sphere, contrary to what Einstein maintained in his General Relativity.

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."

The subsequent switching off of the supermass allows the galaxy to expand outwards again. The author claims to have found just such expansion effects among the globular clusters in our own galaxy. His data are striking and quite convincing. The notorious "missing mass" problem of cosmology disappears with the cyclic supermass assumption because the time-averaged mass of each galaxy will be much higher than that observed in its normal enervated state. Doesn't this sudden temporary appearance of mass violate the laws of physics? No, says the author, physicists habitually assume a superfluid, superconducting vacuum state, which is the ultimate source of all mass-energy, when they develop their theories of fundamental particles.

An astronaut standing on the moon watching the spot where the sun is about to rise would see first of all two well-recognized phenomena: the solar corona (even though the solar disc is still well below the horizon) and the zodiacal light (sunlight reflected from interplanetary dust). In addition, the astronaut would detect a glow along the horizon itself, as in the illustration. Since the moon is virtually airless, there should be none of those gas molecules and suspended dust particles that cause the sunsets and sunrises that we admire so much here on earth. Still, there must be something suspended above the moon's surface to scatter light from the sun still located just below the horizon. The best guess is that lunar dust particles are ionized by solar radiation and are repelled upwards from the surface and hang there suspended by electrostatic forces. But no one really knows for certain the cause of the glow. (Cowen, R.; "On the Horizon: Clementine Probes Moon Glow," Science News, 145:197, 1994.) Reference.

There is general agreement that alpha particles emitted by radioactive isotopes create the halos. The radii of the rings are proportional to the alpha particle energy, and can thus identify the isotopes in the mineral. Some halos, however, are apparently formed by very short-lived polonium isotopes without any trace of parent uranium isotopes. How can polonium isotopes with half-lives only seconds long get into geologically old mica sans parents? York argues the case for selective local chemical concentration of polonium from fluids in the surrounding rocks. The captured polonium atoms decay almost immediately while the fluid containing the parent atoms passes on. R.V .

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 set of initial conditions leading to the first type of behavior, there was an infinite number of slightly different initial conditions that would lead to the second type of behavior. In other words, systems that we have long thought to be deterministic, like the motions of the planets, may be not only chaotic but indeterminate. Since Sommerer and Ott found their indeterminate system easily, we must face the possibility that the future behavior of just about everything is beyond our capability to predict, even with our best instruments and computers.

Later, an exception was made for those quarks that are firmly locked up inside nuclear particles. They each have 1/3 the electron's charge -- but they never, never escape to the outside world. It was, therefore, counterintuitive when R. Laughlin proposed in 1982 that fractional electrical charges actually could show up elsewhere in physics. The phenomenon that suggests this possibility is the Fractional Quantum Hall (FQH) effect. Physicists reluctantly accepted the likelihood of fractional charges in this well-verified phenomenon; but the experiments demonstrating fractional charge were a bit esoteric -- the fractional charges were not "palpable" enough. Two new experiments have made fractional charges much more tangible. When a layer of electrons, held just above absolute zero, is subjected to a powerful magnetic field, you can almost "hear" the fractional charges. The signals from these experiments have been likened to hail hitting a tin roof.

After lengthy cooling periods, the crystalized diamonds were transported to the surface by fluid, lower-melting-point rocks, such as kimberlite. Many South African diamonds are mined from kimberlite pipes. Diamonds are never pure carbon; they always contain some nitrogen and boron. Occasionally, they harbor tiny radioactive impurities; usually alpha-particle emitters in the uranium-238 decay chain. Alphas emitted by these impurities have well-defined energies and penetrate the diamond matrix only so far. If one examines a diamond with a high-power microscope (say, at 100 x), one can see concentric rings surrounding the impurities. These dark radiohalos or "pleochroic" halos have specific radii and can be used to identify the radioisotopes that produced them. So far, so good; but: "The fact that fully formed, optically visible internal radiohalos in diamonds are now presented casts a considerable shadow over current theories of diamond genesis." Actually, the radiohalos pose three challenges to diamond-genesis theory. Problem 1. The half-lives of the halo-creating radioisotopes are measured in thousands of years rather than the billions prescribed for crystallization. ...

No, it was not a dentistry journal, nor was it an ad for a new toothpaste. It was Current Anthropology. It seems that some human and near-human skeletons possess teeth with the peculiar grooves shown in the sketch. The skeleton-age range is huge: 1.84 million years to comparatively modern bones 10,000 years old. These teeth are found on several continents. Some archeologists say simply that ancient humans just picked their teeth a lot in order to remove trapped food particles. But the grooves do not seem to be correlated with dental-decay problems. This fact has led to the so- called "cultural" theory, which holds that the picking of teeth was just another bad human habit, probably a sort of stereotype behavior having nothing to do with food caught between the teeth. (Formicola, Vincenzo; "Interproximal Grooving of Teeth: Additional Evidence and Interpretation," Current Anthropology , 29:663, 1988.

If one does not count the rather primitive notion of Air, Fire, Earth, and Water, there are five basic levels of compositeness: (1 ) molecules; (2 ) atoms; (3 ) nuclei; (4 ) nucleons; and (5 ) quarks and leptons. But now physicists are beginning to see regularities in the lowest accepted layer, quarks and leptons, that betoken a sixth layer of compositeness or subdivisibility. In other words, quarks and leptons are not really fundamental and instead are composed of something else, which will undoubtedly eventually receive fanciful names. In this article, O.W . Greenberg delves into this sixth stratum and the "regularities" it engenders.

And a number of experiments are showing hints that a neutrino has a small mass and that it can oscillate from one variety to another." These experiments are not yet conclusive; and if the neutrino mass is not zero, it hardly weighs more than the grin of a Cheshire cat. But taken together, the laboratory results confirm that neutrinos are perplexing particles. Are they different entities or a single species wearing different costumes? The implications of the recent measurements are far-reaching: Physicists believe that there are a billion neutrinos around for each nucleon (proton, neutron, etc.) so that if neutrinos possess just a hint of mass, they will dominate the mass of the universe; and Measurements of solar neutrinos fall short by a factor of three of what theory says the sun should spew out. This discrepancy could be explained if the solar neutrinos change from electron neutrinos to another form during their flight from the sun to earth, for the terrestrial neutrino detectors measure only electron neutrinos.

Crew suggests in this paper that two rare classes of meteorological observations may be created by the intense electrostatic accelerating forces present in lightning channels. The first class of observations consists of blasts of hot air noted some distance from violent lightning strikes but seeming associated with the discharges. Second, some superhailstones (hydrometeors) also seem to be correlated with violent lightning. The physical mechanism for the concentration and propulsion of matter is the electrostatic force naturally present in lightning discharge channels; it functions much the same as the particle accelerators in the physics lab. The observations of hot air blasts and superhailstones collected by Crew to support his theory are indeed suggestive, but more are needed. Crew also feels that some UFO sightings may be produced by the same mechanism. (Crew, E.W .; "Meteorological Flying Objects," Royal Astronomical Society Quarterly Journal, 21:216, 1980.) Comment.

The ring system of Uranus was discovered by studies of similar stellar occultations. Sure enough, astronomers at the European Southern Observatory, in Chile, and the Cerro Tololo Observatory, also in Chile 90 kilometers away, detected a 1-second, 35% reduction in the star's light at the same instant. These data indicate the presence of an object 10-20 kilometers wide -- hardly an undicovered satellite, but possibly a ring. But given the geometry shown, there should have been two occultations, but only the one on the right was registered. Speculation is now rife that Neptune has a partial ring or a grotesquely twisted one. (Eberhart, J.; "Signs of a Puzzling Ring around Neptune," Science News, 127:37, 1985.) Comment.

They fell in three broad categories: arcs, patches, and 'meteors' similar in appearance to comet comas. Though I at first dismissed the possibility of their being related to meteors, I reconsidered this relation after eliminating other possible causes such as reflections from aircraft lights and tricks of vision. Their meteor-like behavior suggested that perhaps these events might be caused by clouds of exceedingly small meteoroids, visible only because of their numbers and compact grouping. Because such a formation would be unlikely to be maintained long in space, it appeared necessary that the particles involved must have maintained some weak physical contact until just prior to becoming visible. Perhaps some type of 'cosmic dust bunny,' disrupted by air resistance, might be the cause of these events."

This apparent plasticity in the laws governing the cosmos is suggested by observations of how galaxies in the early universe were distributed. The standard theory for the origin of the universe predicts that clumps of galaxies of all sizes were created early on. This is not what a survey by S. Sarkar et al, at the University of Oxford, found. A split second after the Big Bang, galaxies were organized in structures about 300-million light years across. The standard model of particle physics cannot account for this preferred size.

He found the compound, which became a money-spinner for Philips, in a mixture of titanium and radioactive tritium.

No process known to physics could account for such a baffling phenomenon: radioactivity should be unaffected by heat.

(Gribbin, John; "New Kind of Matter Turns Up in Cosmic Rays," New Scientist, p. 22, November 10, 1990.) The original report appeared in Physical Review Letters , 65:2094, 1990. In it, the Japanese scientists describe their balloon-borne equipment, proving that one does not need fancy spacecraft to make important discoveries. The key feature of the quark nugget is its very high mass-to-charge ratio. Where do quark nuggets come from? The theoreticians surmise that they may be created when neutron stars collide or, perhaps, they are left over from the hypothetical Big Bang.

... 8 inches thick and moving at about 200 mph. 'It's unusual in the fact that it fell from the sky,' said Craig Robinson, curator at the planetarium. 'That does not happen often.' A 13year-old boy was in his backyard Monday with a friend when the ice came 'whirling' from the sky and smashed into the fence about 10 feet away from them." The remainder of the article gives the opinions of some scientists who were contacted about the fall. The director of the observatory thought the ice probably fell off the wing of an aircraft. The director of the American Meteor Society suggested a cosmic origin, providing the ice were pure. An astronomy professor assured everyone that it couldn't be cometary, because the sun would melt particles of ice in outer space. Instead, he opted for strong thunderstorm winds picking the ice up from "somewhere" and dropping it on Hartford!

... All Issues This Issue Sourcebook Project Sourcebook Subjects Outrageous Earthquake Waves "Shock waves produced by earthquakes travel faster through the earth when going in a north-south direction than when they travel east-west. "When these waves, called seismic waves travel east-west they take two seconds longer to reach a point on the other side than if they travel north-south. The measurements of velocity take the slightly wider girth of the Earth from east to west into account." D. Anderson, director of Cal Tech's seismological laboratory states, "all of the possible explanations of this phe nomenon are outrageous." The "least outrageous" explanation for the anomaly is that the earth's outer core is not a pure liquid, but more like a slurry of aligned solid particles.

... and the sand-blasted surfaces all attest to the desertification of Mars. Ronald Greeley, of Arizona State University, and his colleagues have simulated Martian winds in a special wind tunnel at NASA's Ames Research Center. Using spacecraft-measured wind velocities and patterns, they tried to duplicate the Martian erosional environment. The results were a surprise. They implied that the Martian surface should be worn down by wind-driven sand and dust at rates up to 2 centimeters per century. But at that rate, the Martian craters, which are estimated to be hundreds of millions of years old, would have been worn level long ago. The researchers are now wondering what is wrong with their simulation. They venture that the Martian sand may not be "normal," or perhaps the eroding particles do not travel as fast as they figured. (Anonymous; "The Windblown Planet Mars," Sky and Telescope, 68:507, 1984.) Comment. Another interpretation is that Mars has not been desert-like for as long as presently believed. Reference.

... Danish astronomer. He has gone so far as to say that our planet boasted rings on 16 separate occasions in the past 2800 years. "Kaare Rasmussen of the National Museum in Copenhagen carried out a survey of all reports of meteorite falls, fireballs and showers of shooting stars from 800 BC to 1750 AD. He then carried out a statistical analysis of the data. He discovered that there were many distinct periods of intense activity." Rasmussen found that the active periods, during which he believes a ring existed about the earth, began with a peak of high meteoritic activity as the ring formed, as a consequence of the earth's capture of a comet or asteroid. This was typically followed by a decrease of activity indicating ring stability. Finally, the ring broke up as its particles were decelerated by the earth's upper atmosphere, leading to another peak of activity. Thus, the plot of me-teorite activity is U-shaped, as in the figure, with the bottom of the U a bit higher than the normal background. (Gribbin, John; "Will the Earth's Rings Return?"
