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. The article is really too technical for Science Frontiers, but we thought our readers might like to be warned that our concepts of matter are based on infinite quicksand. (Greenberg, O.W .; "A New Level of Structure," Physics Today, 38:22, September 1985.) Comment.

The director of the American Meteor Society suggested a cosmic origin, providing the ice were pure.

But the symmetry of a whole crystal, represented by the exquisite six-fold symmetry of the standard snowflake, must be the consequence of some cooperative phenomenon involving the growing crystal as a whole. What can that be? What can tell one growing face of a crystal (in three dimensions this time) what the shape of the opposite face is like?

The successes of this model have been tempered by the fact that it also implies that Saturn's rings are very young. "Theorists would have no problem with a broad, featureless disk surviving the 4.5 billion years since the early days of the solar system, but features such as spiral density waves are clear evidence that satellites, including the profusion of small ones found near the rings, are draining angular momentum from the rings.

The colliding particles usually fragment one another and in the process release a variety of subatomic debris and energy. Large arrays of detectors surrounding the collision site record the particles as they streak away. Usually the escaping particles can be easily identified; but in 1983 nine strange events were recorded, and more have occurred in 1984. Something both invisible and inexplicable carried off large amounts of energy during these "strange" events. Physicist Carlos Rubbia, of CERN and Harvard, said: "There is no sensible way to explain the missing energy by known particles." Some theorists believe that these anomalous events will be explained only by invoking what is termed "supersymmetry" theory. Supersymmetry predicts that twice as many particles as those known today must exist. Already, physicists are rushing to name the new, though unverified particles. The symmetric partner of the "quarks" will be the "squarks"; the "photon" will be paired with the "photino"; there will be the "selectron" for the "electron"; and so on.

Yet, the half-life of Po218 is only 3 minutes. Since the Po218 has no identifiable pre-cursors in the rock, ". .. how did the surrounding rocks crystalize rapidly enough so that there were crystals available ready to be imprinted with radiohalos by alpha-particles from Po218 ?

The implication is that some components of "mind" may have existed in the very earliest life forms. (Peterson, Ivars; "Microsphere Excitement," Science News, 125:408, 1984.) Comment. Two comments here: First, the word "spontaneous" is customarily employed when describing how atoms unite to form molecules and molecules combine into polymers, which then gather into microspheres. The word "spontaneous" seems to imply chance is operating rather than design. Actually, atoms and even subatomic particles must have innate properties which force them to combine into larger structures the way they do. Philosophically, one can ask whether the lowliest subatomic particles are "coded" to combine into molecules, microspheres, and living creatures. In other words, the design of life could be inherent in quarks. Second, if nonliving microspheres possess some of the properties of neurons, it is possible that natural, nonliving minds can form spontaneously -- a sort of "natural" artificial intelligence!

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)?

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.

... far beyond his previous thesis, which in essence declared that from statistical considerations life could not have arisen and evolved on earth. Rather, life had to come from outer space, probably in the form of bacteria and viruses. Evolution was and is dependent upon new information arriving from outer space on tiny bits of life. Hoyle now greatly extends his theory: "But where did a knowledge of amino acid chains of enzymes come from? To use a geological analogy, the knowledge came from the cosmological equivalent of a previous era, from a previously existing creature if you like, a creature that was not carbon-based, one that was permitted by an environment that existed long ago. So information is handed on in a Universe where the lower symmetries of physics -- and characteristics of particles and atoms -- are slowly changing, forcing the manner of storage of the information to change also in such a way as to match the physics. It is this process that is responsible for our present existence, and it is the one which our descendants would be fated to continue." To continue his search for the ultimate, Hoyle recognizes that, contrary to what transpires in the inorganic world, life as-a -whole is actually gaining order and information.

... 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.

Although the ash gravitationally settles out within weeks, the aerosols spread around the globe and can remain suspended in the stratosphere for years. Because solar radiation is easily absorbed and backscattered by the volcanic particles, a haziness in the sky and a dimming of the Sun and Moon are produced. Very dense and widespread dry fogs occur, on the average, once every few centuries. The sizes and intensities of some of the largest of them before the modern scientific era have been estimated by several indirect methods. The densest and most persistent dry fog on record was observed in Europe and the Middle East during AD 536 and 537. Despite the earliness of the date, there is sufficient detailed information to estimate the optical depth and mass of this remarkable stratospheric dust cloud. The importance of this cloud resides in the fact that its mass and its climatic consequences appear to exceed those of any other volcanic cloud observed during the past three millenia.

These filaments emit radio energy just like the planetary radiation belts and are presumably held in the grip of a galactic magnetic field. There have been previ-ous hints of a weak and disorganized galactic magnetic field, but this is the first evidence for a strong polar field in our own Milky Way or any other galaxy.

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?

Second, some superhailstones (hydrometeors) also seem to be correlated with violent lightning.

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.

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. Urey, Harold C.; "Biological Materials in Meteorites: A Review," Science, 151:157, 1966. Ref. 2. Bingham, Francis; "The Discovery of Organic Remains in Meteoritic Stones," Popular Science Monthly , 20:83, 1881. Both references can be found in our Handbook Mysterious ...

... expected increasing chaos required by theory. Although the surveys are incomplete, astronomers are discomfited by this early lumpiness. Their theories say that there was not enough time for galaxies to organize themselves into sheets, shells, and skeins. If further "deep" probings of the cosmos confirm this redshift clustering, we may need a new evolutionary scenario. Good bye Big Bang and expanding universe! (Vogel, Gretchen; "Goodness, Gracious, Great Walls Afar," Science, 274:343, 1996. Vergano, D.; "New Evidence of Cosmic Architecture," Science News, 150:239, 1996) In a related news item, Mexican scientists have proposed that most of the matter in the universe (that elusive "dark" matter) may exist in the form of particles they dub "dilatons." Dilatons might also explain the formation of the aforesaid galactic shells. "The Mexican researchers have explored a situation in which G [the gravitational constant], instead of becoming fixed after gravity separated from the other forces [after the Big Bang], has continued to oscillate by a few per cent. They have found that the mass of dilatons required to allow G to vary in this way could account for all the Universe's dark matter." A consequence of an oscillating G would be a varying rate of expansion for the universe -- a sort of ebb and flow of the whole cosmos. One can then visualize galaxies gradually clustering together into shells much as sand particles drift into ripples under the influence of waves along a beach. (Parsons ...
