Shapiro, author of the preceding quote, attributes the simplistic picture of bacteria to medical bacteriology, in which disease-causing bacteria are classically identified by isolating single cells, growing cultures from them, and then showing that they cause the disease in question. In the microscopic real world, bacteria virtually always live in colonies, which possess collective properties quite different and much more impressive than those of the single-cell-in-a -dish!

For several years now, I have intermittently heard a curious low-frequency sound coming from a deep below the high ground around my home in Hampstead Heath in London. Most of the time it is swamped by other noises, because human hearing adjusts sensitivity to compensate for background noise.

Since the proposed projectile hit in very deep water, no crater was dug out. What did survive is called an "impact melt." This is debris rich in noble metals, such as iridium, and contains particles typical of a low-metal mesosiderite. Some 600 kilometers of the ocean floor received this debris.

... et Vie , p. 86, August 1987. Cr. C. Mauge.) Besides being a surprising adjustment of our ideas about stalactite growth, the recognition that microorganisms may play an active role in the subterranean world stimulates two new questions: (1 ) Can we believe any longer that stalactite size is a measure of age, as is often claimed? (2 ) Is the immense network of known caves (some as long as 500 kilometers) the consequence only of chemical actions? It turns out that the earth beneath our feet is not so solid after all. Some 40,000 caves are known in the United States alone. There are thought to be ten times that number that have no surface openings and therefore escape spelunking census takers. And besides caves big enough for humans to crawl into, there exists an immensely greater continuum of cracks, crevices, channels, and pores which circulate air, water, and chemicals in solution. This "crevicular structure" may be continuous for thousands of miles, possibly around the world. Furthermore, it is filled with life forms of great variety, usually blind, and usually related to creatures of the light. A recent article in American Scientist focuses on the evolution of the larger forms of subterranean life, especially the amphipods. Interestingly enough, it doesn't even mention micro-organisms.

Eddy's discovery of abnormal secular periods of solar inactivity (' Maunder minimum' type) offered the opportunity to put the present hypothesis to a crucial test. Using time series of flourish years of creators in science, literature, and painting (AD600-AD1800), it was found that, as expected: Cultural flourish curves show marked discontinuities (bursts) after the onset of secular solar excursions, synchronously in Europe and China; During periods of extended solar excursions, bursts of creativity in painting, literature, and science succeeded one another with lags of about 10-15 years; The reported regularities of cultural output are prominent throughout with eminent creators. They decrease with ordinary professionals. "The hypothesized extraterrestrial connection of human cultural history has thus been considerably strengthened."

R.E . Gentet sets the geological stage in the following paragraph. "The 1849 gold rush to the state of California was the beginning of some of the most unusual reported finds of early man in North America. The gold-bearing gravels of California are recognized as being Tertiary in age, ranging from oldest to youngest Tertiary, depending upon the exact geological setting. At the time these gravels were deposited, volcanic eruptions also laid down lava beds, often tens or scores of feet thick. This occurred a number of times, and together with much erosion since then, have now resulted in table mountains, that is, lava-capped hills where the harder lava has better withstood erosion stresses while surrounding softer material has been swept away. It is under the hard lava beds, in the gold-bearing (auriferous) gravels, where the reported human bones and artifacts were found, not just once or twice, but hundreds of times by miners during the span of time from the 1850s through the 1890s while engaging in mining operations. Findings were spread over a wide geographical area." During the late 1800s, several books and many papers recorded the discoveries. Some of the finds were made by respected scientists of the day.

Falk discovered that an automobile's engine was limited in power by its radiator's capacity to cool it, he applied this thinking to the human brain. The human brain, like the automobile engine, must be kept cool if it is to function well. It follows that if the brain of an animal is not functioning well, the body that brain controls will not perform well either. Overheated brains, then, are sure roads to extinction in the highly competitive natural world. A couple million years ago, two groups of human precursors were competing for dominance in Africa. The group that won and subsequently evolved into Homo sapiens had, according to Falk, a better brain-cooling system. The evolutionary development that probably led to this advantage was a more extensive network of emissary veins, which permitted better dissipation of heat. This, in turn, allowed the evolution of larger brains and dominance by Homo sapiens. Other anthropologists, how ever doubt that such a minor change in the circulatory system could account for the emergence of modern man. (Shipman, Pat; "Hotheads," Discover, 12:18, April 1991.)

Stothers, at NASA's Goddard Institute for Space Studies, decided to look into the possible correlation of solar activity and terrestrial volcanism, he fully expected to find no connection at all. After all, what force generated by small changes in the sun's output could stir up the earth's magma from a distance of 93 million miles? Stothers was surprised. "Stothers analyzed two immense catalogs, published in the early 1980s, that list more than 55,000 known eruptions since the year 1500. Concentrating on several hundred of the moderate-to-large eruptions, he found statistically significant patterns in eruption frequency that match the solar cycle. Eruptions seemed most numerous during the weakest portions of the solar cycle." Further, there was a 97% confidence that the correlation was not a statistical accident. The only cause-and-effect explanation offered by Stothers was negative and indirect. During periods of abundant sunspots, increased solar emissions jar the earth's atmosphere slightly. Communicated to the crust, these slight taps trigger tiny earthquakes that relieve stresses beneath volcanos, thus delaying their eruptions until solar acitivity dies down. Not especially convincing!

But a colony of a million army ants is a sophisticated "super-organism." The colony carries out its legendary raids and can even keep nest temperatures constant to within a degree. An army ant colony seems en dowed with an intelligence far beyond that of any individual ant. N.R .Franks speculates thus: "It seems that intelligence, natural or artificial, is an emergent property of collective communication. Human con-sciousness itself may be an epiphenomenon of extraordinary processing power. Although experts prefer to avoid simplistic definitions of intelligence, it seems clear that all intelligence involves the rational manipulation of symbolic information. This is exactly what happens when army ants pass information from individual to individual through the 'writing' and 'reading' of symbols, often in the form of chemical messengers or trail pheromones, which act as stimuli for changing behavior patterns." During its 20-day stationary phase, an army ant colony scatters about 14 foraging raids directed 123 apart. The heavy line indicates the colony's path during the nomadic phase.

He contends that the human immunodeficiency virus (HIV) is not the cause of AIDS and is, instead, a harmless "passenger" in the bodies of AIDS victims. Naturally, this stance is controversial, and just as naturally we have had cause to mention Duesberg before. Duesberg is back in the news again because his iconoclastic views were prominently featured in a TV documen tary entitled "The AIDS Catch" seen in Britain in June. The scientific community was furious, claiming that the documentary was one-sided and selective. Further, it was maintained that Duesberg's arguments have been completely refuted. Briefly, Duesberg believes that AIDS is not an infectious disease because: Too few T-lymphocytes in the peripheral blood are infected to cause the disease; HIV carriers without symptoms exist; and HIV in pure form doesn't seem to induce Aids in humans or animals. Rather, says Duesberg, AIDS is a collection of symptoms arising from such factors as the repeated use of intravenous drugs and malnutrition. Mainstream researchers think that Duesberg is wrong on (1 ); that (2 ) is irrevelant, since asymptomatic carriers of typhoid and cholera exist; and that (3 ) may be incorrect, since SIV (Simian Immunodeficiency Virus) does induce simian AIDS in monkeys.

We humans know to our dismay that we have the capacity to modify the earth's environment, but could we perhaps exercise better judgment and terraform Mars? C.P . McKay et al have looked into this possibility: "From our analysis, one could propose the following sequence of events: production of CFCs (or other greenhouse gases) starts on Mars and the surface temperature warms up by about 20 K. The regolith and polar caps release their CO2 and the pressure rises to 100 mbar. One of two things could then happen. If there were large regolith and polar CO2 reservoirs, the pressure would continue to rise on its own. If these were absent, the CO2 pressure would stabilize, and additional CO2 would have to be released from carbonate minerals. At this point (perhaps between 100 and 105 years) Mars may be suitable for plants. If there was a mechanism for sequestering the reduced carbon, these plants could slowly transform the CO2 to produce an O2-rich atmosphere in perhaps 100,000 years. If sufficient N2 could also be released from putative soil deposits, and the CO2 level kept low enough, then a human- breathable atmosphere could be produced. (McKay, ...

You see, methane hydrate is very unstable; changes of temperature or pressure on a global basis can trigger the release of immense volumes of this greenhouse gas from oceanic deposits. For example, when the Ice Ages lowered ocean levels by locking up water in the advancing ice caps, pressures on ocean-bottom methane hydrate lessened and, according to some speculators, released enough gas so that the increased greenhouse heating turned back the Ice Ages. (Was Gaia at work here?) On the other hand, if present human activities are truly stoking the greenhouse effect, ocean temperatures should rise, possibly destabilizing methane hydrate deposits and thereby aggravating the greenhouse effect. Such positive feedback could cook the biosphere. (Anonymous ...

... Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Spontaneous order, evolution, and life In our thinking, one of the most remarkable articles ever to appear in Science bears the above title. Most re markable of all is the use of the word "spontaneous" without philosophical comment. The stimuli for the research described are such observations as: (1 ) life exists; (2 ) life evolves; (3 ) the fossil record displays stasis, extinctions, and great gaps between phyla and lesser classifications; and (4 ) disordered molecules move smoothly and surely into the order manifest in the living cell. The question asked in the article is whether science has missed something in its description of the origin and development of life. Just what makes molecules coalesce into cells and humans? The answer given is: spontaneous self-organization ! In other words, there is no guiding external force. Molecules do this spontaneously. There are even computer models being developed, based on a branch of mathematics called "dynamical systems," that describe how this all happens - spontaneously, of course. (Waldrop, M. Mitchell; "Spontaneous Order, Evolution, and Life," Science, 247:1543, 1990.) Comment. When water molecules spontaneously cluster together to form a snowflake, with all its symmetry and order, science explains the process in terms of the properties of water molecules. The same must be true when molecules merge to form life forms. But why do atoms and molecules possess these properties that lead to bacteria, to humans, to ...

... colors. The books's author is R.E . Cytowic, and he has provided some very interesting observations about synesthetites: There is much consistency among them; that is, if the number 5 evokes a red sensation with one, it does with most others, too. Also, synesthetites seem to run in families. Perhaps most significant is the observation that synesthetic experiences seem to be correlated with changes in cortical blood flow!

Science Frontiers ONLINE No. 79: Jan-Feb 1992 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Telepathic Rabbits Well, why not? Our experimental study has tried to bring out the existence of a correlation, at a distance, between the physiological reactions of two rabbits from the same litter who had always lived together. We chose photoelectric plethysmography as being the least traumatic method for the rabbits and the one most capable of giving evidence of the physiological reaction specific to stress. Through this method, we studied the coincidences between the outsets of the two rabbits' emotional reactions. Added to the rabbits' isolation through distance, some experiments involved the setting up of sensorial and electromagnetic isolation boxes. We studied the coincidences occurring between the spontaneous emotional ... bell in one of the boxes. Two series of experiments out of four gave significant results, leading one to think that a conscious or unconscious telepathic link does exist between two rabbits that have close links with each other.

... ) Very briefly, we have roughly 1000 observations by several thousand people, beginning in October 1989 and still continuing. Most witnesses report a dark, triangular object with three bright lights plus a flashing red one in the middle. Size estimates vary from the size of a football field to that of conventional aircraft. The object sometimes hovers for minutes at a time. It also can move very slowly and then suddenly accelerate to high speeds. Some observers report a faint humming sound; others say that it is noiseless. The American Stealth fighter (Fll7) is roughly triangular, and there has been much speculation that people have been seeing this craft on night missions. The characteristics reported for the flying triangle, however, are hardly those of a jet aircraft. But one must always remember that human observers are imperfect. The July 5, 1990, issue of Paris Match presented a remarkable account of an encounter between two Belgian F16s and one of the flying triangles. We use here those portions of a translation provided by R.J . Durant to the Internation al UFO Reporter (15:23, July/August 1990). "On the night of March 30th, one of the callers reporting a UFO was a Captain of the national police at Pinson, and [Belgian Air Force] Headquarters decided to make a serious effort to verify the reports. In addition to the visual sightings, two radar installations also saw the UFO. One radar is at Glons, south-east of Brussels, which is part of the NATO defense group, and one at Semmerzake, west ...
