"Scientists at the National Aeronautics and Space Administration are scratching their heads over how a tiny patch of something managed to grow even though it was exposed to the harshness of outer space for nearly six years. "The mystery growth has been found in a toothpick-sized region on what is known as the Long Duration Exposure Facility. The bussized LDEF was launched in 1984 and was retrieved by a space shuttle in January 1990, a few weeks before its decaying orbit would have sent it crashing back to earth. .. .. . "NASA scientists in Huntsville, Ala., discovered the growth while examining a brownish discoloration on a Tefloncovered section of the satellite. "Using an electron scanning microscope, they saw tiny, stalactite-like structures on the Teflon. Tiny means the longest were about seven microns in size. That's about one-tenth the width of a human hair. "At first NASA scientists thought the growth might be a fungus or a mold that had contaminated the LDEF upon its return.

... was a bad move, for he immediately experienced a numbing and burning in his mouth. The reason for this, it turned out, was because the skin and feathers of pitohuis are loaded with homobatrachotoxin, a type of poison. This discovery makes the pitohuis the first known poisonous birds. Like many other poisonous animals, the pitohuis also emit a foul odor and advertise their unsavory nature with bright colors. (Dumbacher, John P., et al; "Homobatrachotoxin in the Genus Pitohui : Chemical Defense in Birds?" Science, 258:799, 1992. Also: Anonymous; "Bird with a Sting in Its Tail," New Scientist, p. 10, October 31, 1992.) Comment. As we see from the diagram, homobatrachotoxin possesses a rather complex chemical structure. One wonders how the pitohuis acquired the ability to synthesize it through random mutations. The puzzle deepens when one discovers that homobatrachotoxin is also manufactured by the New World poisondart frogs. Although far-separated taxonomically, both species traveled along the same path of random mutations to achieve this evolutionary convergence.

It should he remarked that about 5,000 years ago, the New Grange passage grave in Ireland was constructed with a special channel to admit light to the central chamber only at sunrise on the year's two equinoxes. A stone chamber in the Gungywamp Complex, in Connecticut, possesses a similar light channel. (See MSU1 in Ancient Structures.)

Science Frontiers ONLINE No. 116: Mar-Apr 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue 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.

... submarine canyons cut into the continental shelves of Alaska and Siberia emphasize once again the colossal scale of these crustal gashes: "Erosion of some of the largest known submarine canyons has removed more than 20,000 km3 of former subduction margin between the Aleutian Islands and Cape Navarin, U.S .S .R . The canyons are incised as deeply as 2,400 m into Tertiary sedimentary and igneous rocks that make up the margin and attendant deep sedimentary basins along the outer Bering shelf. Cutting of the seven major canyons probably occurred during low stands of sea level when the Bering shelf was exposed to a depth of about -135 m, which allowed the ancestral Anadyr, Yukon, and Kuskokwim Rivers to carry large volumes of sediment to the outer shelf. Although their positions appear to be structurally influenced, the canyons apparently were cut by combinations of massive slumping and sliding of sediment deposited near the shelf edge and of scouring action of the resulting turbidity currents that carried debris to the abyssal sea floor, where deep-sea fans have formed." (Carlson, Paul R., and Karl, Herman A.; "Ancient and Modern Processes in Gigantic Submarine Canyons, Bering Sea," Eos, 64:1052, 1983.) Comment. The authors believe that submarine slumping and turbidity currents were sufficient to have eroded these huge canyons. Other geologists doubt this. The other possibility is that sea level was once a mile or more below present levels and that the canyons were cut by rushing water spilling over the continental shelves. Reference.

This novel observation -- that viruses are able to injure their hosts in ways not previously suspected -- may trigger a far-reaching search for viruses as causes of many unexplained human diseases." Some of the other types of diseases mentioned as possible consequences of virus infection are those involving the faulty manufacture of insulin, neurotransmitters, hormones, and immune system regulators. (Miller, J.A .; "Subtle is the Virus: Cells Stay Intact," Science News, 125: 70, 1984.) Comment. This item dwells on the negative aspects of vial infections. Indeed, we automatically assume every infection by any virus or bacterium to be bad for the organism. This may not be so. Now that we have discovered that viruses can cause bodily changes without damaging the cells of the infected organism, we should ask whether favorable physical changes might not be caused by viruses, but not recognized as such. Going a few steps further: Is intelligence a disease? Could evolution be accelerated or directed through the mediation of viruses? See below for more on this.

Williams and Gilbert, for example, have found that a number of Passiflora species, which are heavily defoliated by the larvae of Heliconius butterflies, have developed tiny structures that closely resemble in size, shape, and color the eggs of these butterflies. Heliconius butterflies, when searching for likely plants on which to lay eggs, tend to avoid plants that already have eggs on them. The plants' fake eggs, then, help protect the plant from predation. (Williams, Kathy S., and Gilbert, Lawrence E.; "Insects as Selective Agents on Plant Vegetative Morphology....."; Science, 212:467, 1981.) Comment.

... with ease and alacrity. The 2.5 million multiton limestone blocks in the Great Pyramid are more than ample proof of their ability to work this soft stone. But how about the polished black granite walls of the King's Chamber in the Great Pyramid and the hollowed-out sarcophagus of obdurate chocolate-colored granite in the same room? These granites are much harder than limestone and even harder than the copper saws and drills that the Egyptian stoneworkers had at their disposal. So, how did they work their granite? [No lasers allowed!] The King's Chamber in the Great Pyramid is encased with multiton blocks of hard-to-work granite. For some reason the five granite slabs in the ceiling were finished on only their bottom sides. (From: Ancient Structures) As a matter of fact, there is little mystery here despite what you read in the popular magazines. The Egyptian workers simply dribbled quartz sand beneath the copper saws and drills. This abrasive is harder than the mica and feldspar components of granite but not the quartz. Nevertheless, granite will yield slowly to the abrasive, as do the copper tools themselves. In 1999, D.A . Stocks tested the efficacy of copper saws and drills on the granite in the Aswan quarries 500 miles up the Nile. The copper saw in his test was 1.8 meters long, 15 centimeters in depth, and 6 millimeters thick. Stocks experimented with both wet and dry sand and smooth and notched saws. In one test, workmen cut a slot 3 centimeters deep and 95 centimeters ...

... less well known that life's domain extends down much further. The hard rocks and strata of earth's crust -- seemingly sterile and inert -- are continuously being transformed by bacteria and other life forms. In fact, it was easy to find three examples of such processes from the literature collected from the past two months. Although the discoveries reported below may seem dull to anomalists ued to more exciting fare, it may well be that life from "inner space" has been and will be more important to humankind than life from "outer space," as implied in third item! Bacteria and placer gold. "Lacelike networks of micrometresize filiform gold associated with Alaskan placer gold particles are interpreted as low-temperature pseudomorphs of a Pedomicrobium -like budding bacterium. Submicron reproductive structures (hyphae) and other morphological features similar to those of Pedomicrobium occur as three-dimensional facsimiles in highpurity gold in and on placer gold particles from Lillian Creek, Alaska." In short, bacteria help create placer gold deposits. The author believes that bacterioform gold is widespread.

At least 500 million years ago, filamentous bacteria and/or fungi were already playing vital roles in the deposition of iron from hydrothermal fluids. Abundant microbial filaments indicative of biological activity are found in the Cambrian ironstones in Australia's Thalanga deposit. (Duhig, Nathan C., et al; ...

Certainly an entertainment factor exists, too, for Maddox cannot resist printing a curious little contribution by Peter Stanbury, entitled "The Alleged Ubiquity of pi." Stanbury has discovered a large number of relations between the masses of the fundamental particles that are closely related to pi. Four representative examples follow: The proton-to-electron mass ratio is almost exactly 6pi5 ; The sum of the masses of the basic octet pio, pi +, k +, k-, ko, k-baro is 3.14006 times the proton mass; The sum of the masses of the baryon octet is very close to pi2 times the proton mass; and The reciprocal of the fine structure constant, 137.03604 is close to 4-pi3 + pi 2+ pi , or 137.03630. There are many more such relationships. Further, the ratios 1.0345 and 1.1115 keep popping up more frequently than coincidence would seem to allow. What could these ratios be? At least pi has geometrical significance. (Maddox, John; "The Temptations of Numerology," Nature, 304:11, 1983.) From Science Frontiers #29, SEP-OCT 1983 . 1983-2000 William R. Corliss ...

Current thinking is that these Martian formations are indeed growths, though lifeless ones, much like those mineral spires that sprout around the edges of mineral-rich lakes. The tufa mounds and towers at Mono Lake, California, are good examples, but on a much smaller scale. On Mars, the growths are probably frozen carbon dioxide. The Martian "ghost forests" are probably frost ferns or mineral growths. (Gravitz, Lauren; "Ghost Forests of Mars," Discover, 22:18, November 2001.) Reference.

Barrow's new book, Pi in the Sky , T. Siegfried first reiterates a point made in past issues of SF, namely, that mathematics is a logical system and that we have no right to expect it is correspond structurely with a physical system. In other words, math and nature are fundamentally different entities. Nevertheless, as Barrow stated in a recent interview: "If we were just inventing mathematics from our everyday experience, we would find that it would work really rather well in those areas from which that intuition was gained. But we find almost the opposite...It works most powerfully and persuasively in areas that are farthest removed from the everyday experience that has led to it." Mathematics, for example, leads to verities in quantum mechanics far outside the realm of daily experience. Why is this so? The puzzle deepens when one discovers that there are different kinds of math based upon different forms of logic (as in Euclidian and non-Euclidian geometries). Some brands of mathematics mirror reality better than others. Why? In trying to dispose of these "whys," both matematicians and scientists fall back on the anthropic principle with all its unsatisfying tautological overtones: ". .. the universe is the way it is because that's the way it has to be for anybody to be around to study it.
