They occur worldwide on the floors of all of the oceans and even some lakes. They are found in shallow waters and at depths of thousands of meters.

Not only is the magnetic axis of Uranus tilted grotesquely away from the planet's axis of rotation, but the latter lies almost in Uranus' orbital plane. Q1. Why are the magnetic fields of Neptune and Uranus tilted at such grotesque angles with the axes of rotation? A1. Probably because of giant impacts. Q2.

We have already reported on the mysterious light flashes (SF90) and radio emissions (SF#94). Now, we record similar, possibly intimately related flashes of energy in a different portion of the electromagnetic spectrum. "Detectors aboard the Compton Gamma Ray Observatory have observed an unexplained terrestrial phenomenon: brief, intense flashes of gamma rays. These flashes must originate in the atmosphere at altitudes above at least 30 kilometers in order to escape atmospheric absorption and reach the detectors." The energies of the gamma rays in the flashes are very high. They are typical of the braking radiation (Bremsstrahlung) from 1,000,000 electron-volt electrons. Since most of the gamma flashes originate over regions where thunderstorms are frequent, it is tempting to associate them with lightning. Ordinary lightning, however, is not energetic enough to generate the gamma flashes and, of course, it does not occur above 30 kilometers altitude anyway. G.J . Fishman et al, who reported on this new phenomenon in Science, speculate that some hitherto unrecognized, high altitude electrical discharges occur high above areas hosting thunderstorms. Possibly, upwardly directed lightning (" rocket lightning") is involved in all three of the newly found flashes in the radio, optical, and gamma portions of the electromagnetic spectrum. (Fishman ...

Startling though these seiches were to Gulf fishermen, most seiches are wellexplained.

It is almost as if binary galaxies emulate those dumbbell-shaped molecules that can spin around only at specific frequencies! Can the mechanics of the very large (galaxies) be quantized like the very small (atoms and molecules)? Tifft obviously thinks so: "Quantization, it seems, is a basic cosmological phenomenon. It must reflect some master plan." The Finnish physicist, A. Lehto, has proposed such a plan. "The new cosmology pictures the uni-verse as a set of timelines splaying outwards from a common origin in three-dimensional time. The "time" that we measure is related to our own line. Time along distinct lines is quantized and can even run at different rates." If you feel as if you are walking on a conceptual quicksand, you are not alone. (Beware, the quicksand may be quantized, too!) Tifft believes that this new sort of cosmology can explain: (1 ) the observed quantized redshifts; (2 ) the "missing mass" of the universe; (3 ) "discordant" redshifts (where objects apparently at the same distance from us have grossly different redshifts); and (4 ) the dichotomy between quantum physics and conventional dynamics.

The complexity of the organic molecules found on these particles has fueled the imaginations of many who ponder the role extraterrestrial matter may have played in the prebiological evolution of organic material on the primordial Earth." Beyond these conjectures, several other things about interplanetary dust particles bother scientists: "' What is surprising,' Walker notes, 'and still not understood, is the fact that the organic molecules we see in the dust particles are different from those previously seen in meteorites.' Another enigma is the observation of striking isotopic anomalies -- large enrichments of deuterium relative to hydrogen, as much as ten times greater than one sees in terrestrial samples -- in the particles in which Zare's group observed the organic molecules."

Caterpillars may yield a family tree different from that inferred from the butterflies. Which is correct, or are they all correct? Back to the review. Waxing heretical, Williamson points out that an organism may have more than one phylogeny ! Larvae may have ancestries different from the adults. How heretical can one get? But in the ocean, spermatozoa often cannot find an egg of the correct species. They may then fertilize eggs of a distantly related species. In such "wide hybrids," the larvae may resemble one parent and the adults the other. There is much more.

This bird, according to several observers, does not have to fly with its mouth agape to catch insects like its relatives (whippoorwills, etc.).

Scientists have been known to "spin" data like politicians! A classic case of scientific "spin" occurred in connection with the total solar eclipse of 1919. British astronomer A. Eddington had mounted expeditions to Sobral, Brazil, and the island of Principe off the west coast of Africa. He had telescopes set up at these two locations to measure the bending of starlight by the sun, as predicted by Einstein's Theory of Relativity. In 1919, Relativity was not yet the cornerstone in the Temple of Science that it is today. Eddington "believed" in Relativity and wished to make it more acceptable. Eclipse photos showing the shifting of star images by the gravitational influence of the eclipsed sun might do the job. On the day of the eclipse, Principe was bedevilled by clouds, and only 2 photographic plates were deemed marginally acceptable. At Sobral, 18 poor plates and 8 better plates were obtained. The problem was that the 18 poor plates yielded a deflection of starlight much smaller than predicted by Relativity, while the 8 better plates produced a much higher value. By adding the 2 plates from Principe to the mix, Eddington managed to come up with a number close to that required by the Theory of ...

... revealed a deep fault which "was gushing oil like a garden hose." The deep-seated oil source at Eugene Island strongly supports T. Gold's theory about The Deep Hot Biosphere . Gold holds: "that oil is actually a renewable, primordial syrup continually manufactured by the earth under ultrahot conditions and tremendous pressures. As this substance migrates toward the surface, it is attacked by bacteria, making it appear to have an organic origin dating back to the dinosaurs." The apparent deep-seated oil source at Eugene Island and Gold's ideas make petroleum engineers wonder about a similar situation at the seemingly inexhaustible oil fields of the Middle East. "The Middle East has more than doubled its reserves in the past 20 years, despite half a century of intense exploitation and relatively few new discoveries. It would take a pretty big pile of dead dinosaurs and prehistoric plants to account for the estimated 660 billion barrels of oil in the region, notes Norman Hyne, a professor at the University of Tulsa in Oklahoma.

(SF#86) In a similar vein, some manmade chambers, such as New Grange (3 ,500 B.C .) were configured to enhance the subjective effects of ritual chanting. (SF#102) A fascinating article in Pour la Science , has described how ancient paintings in some of Europe's famous decorated caves were placed where sound resonated. To illustrate, examine the accompanying illustration of the north wall of the Jeannel Gallery of Portel Cave, in Arlege. The long, looping dotted line indicates the amplitude of resonating sound at a frequency of 95 Hertz, as the long gallery behaves like a giant wind instrument. The peak occurs smack in the center of the decorated area. At the peak, in the dotted circle, there is a rocky projection in the shape of a (hard-to-see) feline head. On the opposite wall (not shown), the same peak coincides with an ocher circle that dominates a meter-long decorated panel.

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. (Levin, Theodore C., and Edgerton, Michael E.; "The Throat Singers of Tuva," Scientific American, 281:80, September 1999.) Comments. The human throat is obviously a complex musical instrument, but what survival value does this remarkable instrument have? Did evolution overshoot its mark? Incidentally, many birds can produce simultaneously two tones that are not harmonically related. However, these birds have a special doublebarreled organ called the syrinx. So, the avian "two-voice" phenomenon is not as unexpected as it is in humans.

Men with hands that are not precise mirror images of each other tend to produce fewer sperm. Manning asserts, "The more asymmetry, the fewer sperm." Easier to test yourself are the relative lengths of your ring and index fingers. Men tend to have ring fingers that are longer than their index fingers. The greater this difference in males, the higher their levels of testosterone, a hormone associated with fertility. In women, the same fingers are usually about equal in length. However, in contrast to males, larger index fingers are correlated with the increased presence of fertility hormones, such as estrogen and lutenizing hormones.
