... rods of the protein "tubulin." Somehow , when cells are about to divide, they synthesize these microtubules, which then seem to organize themselves into orderly arrays (the bipolar spindles). Then, the microtubules sort out and separate the two sets of chromosomes required for the two new cells. So, far, our description conforms to what biologists have known and accepted for decades; but there is something more mysterious going on. In 1996, researchers discovered that they can actually substitute DNAcovered beads for the chromosomes, and the microtubules will still go through the motions of sorting and separating the chromosome-less strands. Actually, the microtubules will perform their act even without the DNA-covered beads. In a sense, the bipolar spindle is a puppetmaster, and the microtubules are the strings. The puppet show can go on without the puppets (chromosomes). (Hyams, Jeremy; "Look Ma, No Chromosomes," Nature, 382:397, 1996.

... years ago, the king's loyal subjects grubbed up the thin island soil and piled it up into high mounds. Tonga's pigeon-snaring mounds did not compete with Monk's Mound sizewise, being at most 115 feet in diameter and perhaps 15 feet high. But that's still a lot of dirt. On the tops of the mounds were smaller, beehive-shaped mounds with vertical slits in them large enough to conceal a human. From these blinds, the king and princes would swing nets on the ends of 12-foot poles to catch pigeons. Of course, no self-respecting wild pigeon would ever fly over such a suspicious hill without some enticements. So, captive pigeons caged on the mound were set to cooing and other pigeons tethered by long strings were launched. Sure enough, wild pigeons were lured close enough to be snared.

... Sourcebook Project Sourcebook Subjects "A FANTASTIC RESULT!"That's what Princeton astronomer N. 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. So much rides on this one assumption. The same situation prevails in biology, where everything is founded on the assumption that random mutations and natural selection can together generate any degree of complexity, sophistication, and innovation seen in nature. The history of science tells us that many paradigms have fallen because they depended upon faulty assumptions. From Science Frontiers #116, MAR-APR 1998 ...

Cosmic rays have now been pro-posed as both a source of charged particles and a provider of low-resistance ionized conduits for lightning to follow. Primary cosmic rays carry considerable energy, most of which appears near the earth's surface in the form of cascades of secondary particles that create complex ionized tracks as they penetrate the dense lower atmosphere. Lightning bolts would tend to follow these precursors along their crooked trails. (Anonymous; "Do Cosmic Rays Trigger Lightning Discharges?" New Scientist, 77:88, 1978.) Comment.

It has long been a cornerstone of modern science, to say nothing of man's cosmic outlook, that the earth attends a modest star that shines in an undistinguished part of a run-of-the-mill galaxy. Life arose spontaneously and man evolved on this miscellaneous clump of matter and now directs his own destiny without outside help. This cosmic model is supported by the Big-Bang and Expanding Universe concepts, which in turn are buttressed by the simple observation that astronomers see redshifts wherever they look. These redshifts are due, of course, to matter flying away from us under the impetus of the Big Bang. But redshifts can also arise from the gravitational attraction of mass. If the earth were at the center of the universe, the attraction of the surrounding mass of stars would also produce redshifts wherever we looked! The argument advanced by George Ellis in this article is more complex than this, but his basic thrust is to put man back into a favored position in the cosmos. His new theory seems quite consistent with our astronomical observations, even though it clashes with the thought that we are godless and making it on our own. (Davies, P.C .W .; "Cosmic Heresy?"

Planetesimals in these arms cra-ter the solar-system planets at these times and also provide the raw materials for new comets, asteroids, satellites, and even planets. Supporting their theory is the repeating history of geological revolutions with the accompanying extinctions and reflowerings of life. A remarkable feature of this paper is a table of shortlived solar-system phenomena (comets and rapidly evolving staellite-and-ring systems). The tenor is one of episodic catastrophism and a rapidly changing solar system; viz., Saturn's rings evolving in only 104 years.

A quipu appears to the uninitiated as a meaningless jumble of strings. To an Inca quipu reader, though, the positioning and colors of the secondary and tertiary strings appended to the primary cord all have meaning. The knots along each string also convey messages. Quipus incorporated, in a sense, three-dimensional notation, as opposed to the two-dimensional text on this page. Inca mathematical developments are inherent in quipu notation, which clearly reveals base-of10 positional notation and the use of the zero. Instead of a tangle of colored strings, the quipus actually display sophisticated concepts of number, geometrical configuration, and logic. (Urton, Gary; "Inca Encodements," Science, 216:869, 1982.)

Kirshner et al carefully measured galactic redshifts in three widely separated regions of the sky and found almost no galaxies in the redshift velocity interval 12,000 to 18,000 km/sec in all three areas. One interpretation of this huge gap is that the initial post-Big-Bang distribution of matter in the universe was unexpectedly lumpy.

Most of these figures and lines are so large that one can fully appreciate them only from the air. This fact has led some writers to invoke ancient astronauts and even ancient Peruvian balloon technology. The fact of the matter is that archeological evidence is pretty convincing that the Nazca Indians constructed the lines about 500 A.D . But did they have extraterrestrial help or use some advanced technology? The author of the subject article, with the help of a few friends, answered these questions quite convincingly -- in the negative -- in the summer of 1982. Using sticks and string, they scaled up a small copy of the famous Nazca "condor" into a 440-foot replica of the real thing on a Kentucky landfill. The scaling up involved no high technology; in fact, even angular measurements were avoided. Instead of removing stones to make the lines, as the Nazcans did, lime was applied. The whole figure was laid out and limed in just a few man-hours. Then, from an aircraft at 1,000 feet, photos were taken. Lo and behold, a very convincing replica of the Nazca condor appeared on the prints. Still unanswered, though, is why anyone would want to make such huge drawings.

The fragments are peculiar because they appear not to travel as far as expected in the special "nuclear" emulsion used to study the interactions of high-energy nuclei from heavy-ion accelerators or in cosmic rays. This suggests that the anomalons are either much larger than conventional nuclei, and are more likely to interact in the emulsion and therefore do not travel so far, or are some unusually long-lived form of matter, lasting for around 1011 seconds or more."

These subtractions enable us to determine how the 390 elliptical galaxies move relative to the cosmic background radiation -- which is about the best fixed reference frame we can come up with. For roughly 50 million parsecs in all directions from earth, the clusters and superclusters of galaxies are streaming through the cosmos in a group.

Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more.

But surely the immensely more complicated molecules of biology cannot be synthesized near absolute zero.

To achieve molecular synthesis, repulsive barriers must be overcome. The warm temperatures in that terrestrial pond can provide the extra kinetic energy to climb over these barriers. In cold molecular clouds we must look elsewhere. The laws of quantum mechanics state that there is always a very low probability that atoms and molecules can tunnel through repulsive barriers -- no need to climb over them via thermal effects.

It is about unusual adaptations in nature, as illustrated by three inverted or partially inverted creatures. The flamingo is a filter-feeder that strains food out of the water with its bill while its head is upside-down. The flaming's bill and tongue are (and must be ) radically different from those of other birds to succeed in this strange behavior. One type of jellyfish, rather than swimming around with its pulsating bell on top, plunks itself upside-down on the bottom and uses its bell as a suction cup to anchor itself. It then shoots poisonous darts attached to strings of mucous at passing targets and reels them in. Some African catfish graze on algae on the undersides of water plants. They swim upside down all the time and display a reversed color scheme, being black on the bottom and light on top. Gould employs these three examples to argue that changes in animal behavior must have preceded the many changes in form, function, color, etc. that make upside down living profitable. In other words, the proto-flamingos tried feeding with their heads upside down; and it didn't work too well. But "nature" responded with a series of random biological changes, some of which were just what was needed for efficient upside down feeding.

Instead, he opted for strong thunderstorm winds picking the ice up from "somewhere" and dropping it on Hartford!

... something really incredible,' he says. According to Jordan, the anomalies are analogous to continents on the surface of the earth, because they can't be accounted for by temperature variations but must reflect some compositional change as well. These features 'represent the scum or slag that sits up on the outer core boundary, just as continents sit on the outer surface of the earth,' he says." Some have even speculated that these subterranean chunks of debris are pieces of surface continents that were subducted at the plate boundaries long ago. There are, after all, missing pieces in the continental drift jigsaw puzzle. There might even be substantial chunks of asteroids and comets down there waiting, like the Titanic, to be explored by scientific instruments. Can once-subducted continents and cosmic debris ever rise again? (Weisburd, Stefi; "Seismic Journey to the Center of the Earth," Science News, 130:10, 1986. Also: Kerr, Richard A.; "Continents at the Core-Mantle Boundary?" Science, 233:523, 1986.) Earthquake waves allow seismologists to construct models of the earth's interior. Coninent-sized inhomogenities have been found near the core-mantle boundary. From Science Frontiers #47, SEP-OCT 1986 . 1986-2000 William R. Corliss ...

... Following this lead paragraph, with its paradigm-shaking final sentence, are three pages summarizing the biological evidence favoring evolution by endosymbiosis. (Kite, Geoffrey; "Evolution by Symbiosis; The Inside Story," New Scientist, p. 50, July 3, 1986.) Comment. We cannot possibly do justice to this exciting idea of evolution forced by the uniting of different organisms in the limited format of Science Frontiers. Instead, we encourage readers to purchase a new book by L. Margulis and D. Sagan (son of Carl Sagan and L. Margulis) entitled Micro Cosmos. In passing, we must also remark on the obvious relationship of endosymbiosis to F. Hoyle's "evolution from outer space." Hoyle believes that microorganisms and other biological information are transported in cosmic debris. Finally, the story of Lynn Margulis' uphill fight against scientific skepticism is related in: (Keller, Evelyn Fox; "One Woman and Her Theory," New Scientist, p. 46, July 3, 1986.)
