Science Frontiers ONLINE No. 135: MAY-JUN 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Where Is The Maestro?As we learn more and more about the gene complements of our planet's multitudinous life forms, the more it seems that the vaunted genome may not incorporate all of the information necessary to construct a living organism. Despite assurances to the contrary, we must ask if we really know the whole story. These doubts manifest themselves as we see that creatures that are very much alike genetically may be radically different morphologically. In this vein, C. Ventner asserts that all higher vertebrates have roughly the same genes. The animals that result from these re-markedly similar genomes depend upon when specific genes are turned on and off. Ventner says, "We have the same number of genes as cats and dogs, but differently regulated." The genes themselves are supposed to be simply protein factories. Somehow, they are turned on and off (" expressing" themselves) in just the right sequences to help build the target animal. In a far-stretched analogy, the genes are the instruments in an orchestra and the proteins they produce are the notes in a symphony. But where are the symphony's score and its conductor? Very similar orchestras, it seems, can play radically different symphonies given different scores as interpreted by a maestro. Each living thing is likewise a symphony of proteins, each played by the genome at just the right time. But just where are the score -- ...

Amid much hullabaloo, it was announced recently that the human genome has now been mapped. To everyone's surprise, we are said to be constructed from blueprints containing only about 30,000 genes. But how accurate are these maps that were drawn up so hastily in the bitterly contested race between the publically and privately sponsored programs? How good are those computer programs that identified these 30,000 or so genes? According to W. Haseltine, who heads Human Genome Sciences, "They're reading smudged text through foggy glasses." Haseltine's company claims to have found more than 90,000 human genes. Two other organizations have identified between 60,000 and 65,000 genes. A research group at Ohio State University at Columbus analyzed the same data used by the public consortium and estimates that there are actually human 80,000 genes! In fact, this groups avers, the public consortium's software seems to have missed 850,000 gene segments for which there already exists protein or RNA evidence.

Science Frontiers ONLINE No. 31: Jan-Feb 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The hypothesis of formative causation lives!Rupert Sheldrake's hypothesis has been roundly condemned by many scientists, presumably because it departs so radically from current thinking. Basically, the hypothesis maintains that the forms of things (from crystals to life forms) and the behavior of organisms is influenced by "morphic resonance emanating from past events." Convergent evolution, wherein human eyes closely resemble squid eyes, might well be explained by the hypothesis. Sheldrake has been testing his idea in various ways. One experiment involves the accompanying illustration containing a hidden image. Once the solution of this illustration is learned, it is hard to forget, but few people see the answer right off. The hypothesis of formative causation insists that once one or more persons learn the drawing's secret, the easier it will be for others to see the solution. Actual tests consisted of broadcasting the illustration and its solution (that is, the hidden image) on English television combined with before-and-after checks elsewhere in the world outside TV range. The results strongly supported the hypothesis, for it was far easier for people outside England to identify the hidden images after the broadcast. (Sheldrake, Rupert; "Formative Causation: The Hypothesis Supported," New Scientist, 100:279, 1983.) Comment. With all this prior publicity, the hidden image should pop immediately into the reader's mind. But if it doesn' ...

The southern and western sides were rimmed by a timber-framed rampart 2,500 meters long. The northern flank was protected by a 1,200meter multiditch outwork. "A Neolithic herdsman who looked up to the hilltop in about 3,400 BC would have seen an impressive site. Crowning Hambleton Hill was a huge defensive enclosure with three concentric ramparts. The inner rampart, the most formidable of the three, was supported by 10,000 oak beams as thick as telephone poles. In the ditch around the ramparts human skulls placed at intervals added an eerie note to the appearance of the fortifications." Such a construction feat must have taken considerable organization and community energy, much like the pyramids then under construction in Egypt. In the absence of stone quarries and with plenty of forests, Hambleton Hill's fortress was simple wood and dirt, but nonetheless very impressive. Even its great size, however, did not save it from conquest and burning. (Mercer, R.J .; "A Neolithic Fortress and Funeral Center," Scientific America,, 252:94, March 1985.) Reference.

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. "Specifically, entire atoms can tunnel through barriers represented by the repulsive forces of other atoms and form complex molecules even though the atoms do not have the energy required by classical chemistry to overcome the repulsion." Of course, the reaction rates are slow, but the size of the cosmic pond is vastly greater than any terrestrial puddle. The above quotation is from V.I . Goldanskii who, even before Hoyle, suggested a cold prehistory of life, during which complex organic molecules were synthesized at just a few degrees above absolute zero.

Such finds have forced hydrologists to question their traditional belief that deep aquifers were devoid of life. But it was not clear whether these bacteria were native residents of the aquifers or just contaminants from the world above, living solely within the wells. Moreover, no one had established how the bacteria were affecting the environment, if at all." Experiments have now shown that these subterranean bacteria are indigenous and are important to groundwater chem istry. The bacteria feed on organic molecules and display a curious propensity for metabolizing the carbon-13 isotope rather than carbon-12. Thus, carbon dissolved in some deep aquifer water is enriched in carbon-13 compared to surface water. None of the bacteria found so far seems dangerous to humans.

After some computations Melosh concludes: "It seems likely that the impacts that produced craters on Earth that are greater than 100 km in diameter would each have ejected millions of tons of near-surface rocks carrying viable microorganisms into interplanetary space, much in the form of boulders large enough to shield those organisms from ultraviolet radiation, low-energy cosmic rays, and even galactic cosmic rays.

This evidence of nearby cosmic order does not seriously disturb cosmologists, because in the nearby galaxies we are seeing that portion of the universe that is billions of years old. In other words, nearby there has been enough time for some degree of order to have evolved out of the primordial chaos of the Big Bang. Now though, "deep" surveys of galaxies, looking much farther back in time, still show clustered red shifts -- not the expected increasing chaos required by theory. Although the surveys are incomplete, astronomers are discomfited by this early lumpiness.

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.

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.

You can reasonably ask: "How can supposedly immutable physical laws change?" The answer seems to be that anything can happen when something is being made from nothing! This apparent plasticity in the laws governing the cosmos is suggested by observations of how galaxies in the early universe were distributed. The standard theory for the origin of the universe predicts that clumps of galaxies of all sizes were created early on. This is not what a survey by S. Sarkar et al, at the University of Oxford, found. A split second after the Big Bang, galaxies were organized in structures about 300-million light years across.

Despite their differences, they have always been thought to have evolved from a common ancestor. A more subtle, fundamental difference has now been found. Recall SF#117 and how some terrestrial life forms do incorporate right-handed molecules in their structures, especially in cell membranes? The ubiquitous Eubacteria do this. In the Archaea, however, the same structural components of the cell membranes (glycerophosphates) are left-handed. A subtle difference, but one with deep implications. Some scientists maintain that it is impossible for two organisms relying upon mirror-image versions of the same molecule to have evolved from a common ancestor. Their genomes must be fundamentally different. Conclusion: the Archaea and Eubacteria must have evolved separately, and from different biological wellsprings -- that is, "creations."

Science Frontiers ONLINE No. 73: Jan-Feb 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects An Amusing Assemblage Of Anomalies We don't read much about "waterguns" in the modern scientific literature, but a century ago Nature published many ear-witness accounts of them. These muffled detonations heard near the coasts of almost all the continents are believed by some to be caused by eruptions of methane from the seafloor. The same eruptions probably also account for the myriads of "pockmarks" found in the sediments of shallow seas. Whether this outgassing of methane comes from shallow accumulations of organic matter or from deep within the crust is still debated. Here, geophysics merges with biology. Recently, a group of researchers discovered a large (540 square meters) patch of chemosynthetic mussels in a brine-filled pockmark, at a depth of 650 meters, off the Louisiana coast. The mussels grew in a ring around the concentrated brine. The mussels harbor symbionts which consume the methane still seeping up through the brine from a salt diapir (a massive fingerlike intrusion 500 meters below the brine pool. The origin of some diapirs is not well-understood.) The mussels get the oxygen they require from the ordinary seawater covering the dense brine. Like the biological communities surrounding the "black smokers" and other ocean-floor seeps, the brine-filled pockmark community includes several species of shrimp, crabs, and tube worms. We have here another example of the astounding ability of lifeforms to take advantage of unusual, even ...
