In our more recent library searches, we have come across an old article that provides additional examples of the socalled Bradshaw paintings -- more of those graceful human forms with long, billowing tresses. Very out-ofplace in today's Outback. The same article adds an even more puzzling human representation to the burgeoning file of mysterious Australian art. It is a carving found in a cave of northwestern Australia. Here is the text accompanying the sketch. "Another cave introduced a fresh problem. Fronting it, high up on the vertical face of a cliff, and unreachable without mechanical aid, had been carved out of the solid stone a human head in profile, which I show. It was 2 feet long and 16 inches across, and 1 -inch thick; and I leave my hearers to say whether it is not a striking and distinguished face. It is absolutely different from the heads of modern Aborigines. The worn edges of the cameo, where it joined the rock-surface, seemed to mark a long interval since it was carved; the difficulty of carving it where it stood must have been immense -- unless, indeed, the rock face had been near the ground at the time, and the ground had worn away since - ...

In 1989, the Lancet , a respected British medical journal, published an article relating how a female dog, half border collie, half doberman, sniffed out a spot of melanoma on a woman. In fact, the dog ignored all of the other moles on the woman and even tried to bite off the melanoma. Melanoma is the most dreaded form of skin cancer, so this bizarre report stimulated A. Cognetta, an American dermotologist, to try an experiment. First, another dog, named George, was trained to find tubes containing melanoma samples, which he did correctly 99% of the time. Next, a human with active melanoma was enlisted. Several bandages were placed on the subject's body including one over the melanoma site. Once again, George was almost 100% accurate in his diagnosis. Subsequently, George successfully identified malignancies on other patients. (Walker, Kenneth; "George the Dog Helps Take a Bite out of Skin Cancer," Chicago Sun-Times , September 6, 1998. Cr. J.

Science Frontiers ONLINE No. 107: Sep-Oct 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Subversive Cancer Cells It has been generally believed that most cancers originate in a single founder cell, which then multiplies to create the tumor. But cancer is more insidious than expected. A precancerous founder cell may actually subvert nearby noncancerous cells and turn them into cancerous cells. In this sense, the first precancerous cell recruits and transforms healthy cells, enlisting them in its destructive operations, and thereby turning them against the body that produced them. No one yet knows how this subversion is effected or how it evolved. (Why is there cancer anyway?) The basis for this claim involves a few rare human mosaics, whose bodies are built of cells with two different genetic complements. Cancers in human mosaics have been found to contain both types of cells and, therefore, did not grow from a single cell alone. (Day, Michael; "Cancer's Many Points of Departure," New Scientist, p. 16, June 1, 1996) Comments.

It is now common knowledge that bacteria, insects, plants, and even humans can build up resistances to poisons, diseases, and antibiotics. Mutations are always occurring; some good, some neutral, some bad. It has been found that a human mutation designated CCR5-delta 32 confers immunity to AIDS if inherited from both parents. People carrying the CCR5-delta 32 mutation lack the receptors to which the AIDS virus must attach itself if it is to infect the person. What has all this to do with the Black Death? "Although the origin of the mutation is obscure, it appears to have suddenly become relatively common among white Europeans about 700 years ago. That increase suggests that something must have occurred about that time to greatly favor the survival of people carrying the mutation." What biological catastrophe decimated Europe 700 years ago? The Black Death. One-quarter to one-third of the Europeans succumbed between 1347 and 1350. The Black Death strongly modified the European gene pool, increasing the frequency of CCR5-delta 32. This mutation may not have had any direct effect on the plague itself. It may just be a quirk of fate that the survivors of the Black Death had a higher frequency of the CCR5-delta ...

R.G . Everit responds that this is not really mysterious. The better chess-playing computers are actually designed to behave unpredictably when confronted by several moves of roughly equal promise. This feature makes it more interesting for human players. Everit also sets us straight in the matter of computer determinacy. "However, contrary to your basic assumption, most computers (even a home PC) can be forced to behave truly unpredictably. This cannot be done using the random-number generators supplied with the software, as these depend upon some mathematical formula and so are determined in advance, even if they appear to show no pattern. But if the machine has an internal clock readable by the programmer, he can determine the machine's choice depending upon the time required for some complex calculation, which will vary according to such factors as minute voltage variations and the aging of the machine's components. For example, the CDC 3600, on which I learned to program in 1975, had an accessible microsecond clock, and my program to calculate the first five perfect numbers* required about 15 minutes of run time; the last few digits of the exact number of microseconds required to run this program each time varied quite unpredictably. In other words, it was a random number, except ...

Humans and most of the life forms we are familiar with belong to the latter group. (Curiously, human red blood cells lack nuclei!) However, a third basic type of life has been found prospering in some extreme environments. These are the Archea, typified by the methane-producing microbes discovered clustered around hot deepsea vents, where temperatures may exceed 400 C. It is not their rugged constitutions that place these miniscule forms of life in a new category; it is their genomes. They are radically different from those found in prokaryotes and eukaryotes. The genome of one species of Archea collected from a hot vent 3 kilometers deep in the Pacific has been sequenced. Biologists were taken aback. Methanococcus jannaschii , as it has been dubbed, possesses 1738 genes, of which 56% are entirely new to science. Many of these genes do not look anything like those found in the prokaryotes and eukaryotes. In a word, they seem "alien." (Morell, Virginia; "Life's Last Domain," Science, 273:1043, 1996.)

... January 24, 1998, while drilling to construct a water drainage system at Monk's Mound, workers hit stone -- at least 32 feet of it -- perhaps a region of cobbles or slabs of rock. This region of stone, of undetermined geometry, is located 40 feet below one of the terrace surfaces, but still well above the base of the mound. The stones could well be an artificial structure of some sort. The discovery challenges the current thinking about the culture that built Cahokia. Only further research will reveal the extent and configuration of the stony region and where the stones may have come from. An editorial in the March 14, 1998, St. Louis Post-Dispatch put the Cahokia discovery in the larger context: New World archeology is in flux. Humans occupied the Americas long before 12,000 BP, and some of them may have been Caucasian (e .g ., Kennewick Man). We now quote two incisive paragraphs from this editorial. "This burst of uncertainty surrounding the meaning of the stones beneath Monk's Mound is just the latest discovery shaking what was settled fact. Archeological finds are even challenging the conventional wisdom about when and how the Americas were settled. "It is a humbling and thrilling reminder that in all fields of human inquiry, what we take for certain knowledge at one point in history is highly mutable, subject to continuous revision, revolution and even rejection."

For high hydrodynamic performance, their bodies must be nicely streamlined. For males, this means that their testicles must be stored internally. But dolphins are very active animals, and their muscles generate considerable heat -- too much heat for sperm to survive without some sort of special cooling system. (Recall that human males with undescended testicles may become sterile.) Since dolphins are obviously procreating, evolution must have come to the dolphins' rescue. Evolution's engineering solution installs heat exchangers in the dolphins' tails and dorsal fins. Blood heated in the vicinity of the testes is pumped through special veins in the tail and dorsal fin, where it is cooled by seawater and then returned to the dolphins' heat-sensitive innards. Female dolphins have similar heat exchangers to cool their uteri. The same article in Discover points out still another remarkable adaptation conferred on dolphins: They do not have to expend a lot of energy in diving to great depths. Below about 70 meters, the water pressure collapses their lungs so that they sink like rocks! Of course, returning to the surface does require some exertion.

Then, as board after board of electronic components were disconnected, it burst into the old song A Bicycle Built for Two . It had learned this tune early in its silicon-based life. Surprisingly, real computers can experience similar Near-Death Experiences (NDEs). S.L . Thaler, a physicist at McDonnell Douglas, was studying neural networks designed to mimic the structure and functions of the human brain. Such neural nets can actually learn as programmers train them. As a evening avocation, Thaler devised a program that randomly severed connections in the neural net, in effect destroying the artificial brain bit by bit. When between 10 and 60% of the connections were destroyed, the net spat out only gibberish. Near 90% destruction, though, strange "whimsical" information was produced that was definitely not gibberish. In contrast, untrained neural networks generated only random numbers as they were "put down"! Evidently, HAL's tuneful demise was not so fanciful after all.

Kasparov. Incidental to the match itself was the fact that Big Blue sometimes made different moves when confronted with identical chessboards! With these denials of cyberdeterminism in mind, consider the following anecdote. About 40 years ago, D. Herschbach witnessed the first test of an early chess-playing program written by the renowned S. Ulam for the MANIAC I computer. "In this test, the MANIAC I computer played both sides of the board. After a rather bizarre game, Black made a move that checkmated White. Only then did Ulam realize that the program did not say what to do when mated; it just required that a move be made to escape check. While Ulam and his colleagues debated what might happen, the computer whirred on for about ten minutes. Finally it punched out White's move (on paper tape, then the mode). The uncanny solution: a spurious pawn appeared and began to march down the board to become a new queen." (Herschbach, Dudley; "Computer Milestones," Discover, 17:12, October 1996) Comment.

... 800. (SF#110) The media have said little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm the immense amounts of gases precariously locked up in sea-floor sediments. The stratum of gas hydrates in the Blake Ridge alone covers 26,000 square kilometers -- enough gas is there to supply the U.S . for 107 years. In biological terms the Blake Ridge's carbon is ...

... but pigeons were much more common, and some species were good-sized and delicious. So much so that eventually only island royalty was allowed to catch and eat them. Pigeon poachers were whipped or executed (and maybe eaten?) In fact, pigeon snaring became a royal sport. To this end, starting at least a thousand 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.

Those favoring the "ancient astronaut" theory assure us that the Wandjina figures are those of alien visitors! The so-called Bradshaw paintings don't fit in the "alien" category but they are so interesting that we choose to reproduce one here. It raises three problems: (1 ) The slim, flowing human figures remind one more of the Tassili rock art found in Africa's Sahara rather than that of the Australian Aborigines; (2 ) The objects at the left are enigmatic and technical-looking; and (3 ) The symbols (? ) at the top are undeciphered. The article at hand from Antiquity does not attempt to interpret the Bradshaw art. Instead, it discusses the social factors that mold the interpretation of the Wandjina and Bradshaw paintings. When Europeans first saw these paintings they were certain that their "advanced style" was far beyond the capabilities of the Aborigines (colonial prejudice). They must, therefore, be the work of "preAborigines." Today's Aborigines will have none of this condescension. They were the original settlers of Australia, and as such they have bona fide land and title claims. Any recognition of "pre-Aborigines" would undercut these claims. (McNiven, Ian ...

Lenton answers that there must be feedback loops from the planetary environment that steer the evolution of individuals in the "proper" direction. Lenton goes on to explore some of these many feedback mechanisms; one obscure loop involves the production of dimethyl sulfide by marine phytoplankton. Truly, it is a tangled bank! All of the feedback loops imply that the evolution of life forms is constrained (or dictated) by the need to keep the planet livable and not to simply leave the most progeny, but rather the progeny that will best serve Gaia! (Lenton, Timothy M.; "Gaia and Natural Selection," Nature, 394:439, 1998.) Comments. The obvious implication is that all life forms, including humans, are parts of a planet-sized super-superorganism.

Now, we add two more remarkable capabilities to their dossier. Precision navigation. The oily, flexible shells of leatherbacks have made it difficult for researchers to attach radio transmitters to the animals. Their very deep dives (over 1,000 meters) are also inimical to human instrumentation. But S.J . Morreale's group at Cornell have succeeded in attaching pressure-resistant transmitters to the shells on short tethers. This team was able to track female leatherbacks as they left their nesting beach in Costa Rica and headed southward, past the Galapagos, out into the open South Pacific. Surprisingly, all the leatherbacks plied a very narrow corridor each year of the experiment (1992-1995). In fact, the paths were almost for at least 2,700 kilometers southwest of the Galapagos. Highprecision navigation equipment is required here. Among the leatherbacks' "instruments" are probably sensors that detect the angle of the geomagnetic field, the length of daylight, and the identities of the oceanic currents encountered. There are probably other sensors and, of course, a brain to process all the signals; but virtually nothing is known about them.
