... kind of colonist, we must be the first and only intelligent civilization. Essentially Tipler was criticizing the prevailing notion that, from a statistical point of view, there must be many other civilizations among the numberless stars and galaxies. Tipler's thoughts evoked a richly provocative group of letters, some of which were published in the March 1982 issue of Physics Today along with a closely related article by Ornstein. Ornstein tackled the problem of estimating the probability that intelligent life would evolve on other planets from a biologist's perspective. Whereas some physical scientists have set this probability at about 1.0 , Ornstein inclines toward 10-9 , believing that intelligent life is probably unique to the earth. But concludes Ornstein, the 15 separate developments of eyes among disparate terrestrial organisms may infer some unrecognized directing factor in evolution that would force him to revise his estimate upwards drastically. On the other hand, those 15 eyes might indicate a common, but still undiscovered, eye-possessing ancestor far back along evolution's track. The fossil record might be mute on this matter because eyes are soft tissues that are rarely preserved or perhaps because many eyes were jettisoned because the organisms didn't need them, as cave dwellers are wont to do with surprising rapidity. Some of the letters responding to Tipler questioned whether an intelligent civilization would be stupid enough to build self-reproducing von Neumann machines for galactic exploration. Wouldn't it be far more fun to go in person rather than by proxy? And, some pointed out, von Neumann machines would be ravenous consumers of energy and ...

... , another Britannia Airways Boeing 737 on a holiday flight from Crete to Gatwick (London) had a similar encounter, this one at 5:45 p.m . Descending 15,000 feet, the copilot caught sight of a "small black lozenge-shaped object" some 500 meters ahead and above. The object was on a collision course, and within two seconds it passed the aircraft's wing at a distance of only 100 meters at less than 10 meters above the wing. The crew felt no impact or wake, and the passengers were not alerted. The pilot assessed the risk of collision as high. When reported to London Air Traffic Control Center, the missile was picked up on radar moving away from the aircraft. It was moving at 100 mph in a southeasterly direction and was no known traffic since it had no transponder to identify it. Another aircraft was warned since the unknown target appeared to turn and head toward it, but the other aircraft saw nothing. The radar target, however, may have been a helicopter at a lower altitude. "The sighted object was small, some 1.5 feet in diameter, smooth and round.

This suggestion results from the unusual abundance of fossil material in Africa that is quite ancient in comparison with what is known elsewhere. The theory of an African origin has influenced the interpretation of the age of some non-African archaeologial sites. A case in point is the 'Ubeidiya locality in Israel, which is generally considered to be about 700,000 yr old because it has been assumed by a few that the associated Early Acheulian tool industry, and the persons who used it, would have taken considerable time to disperse from Olduvai Gorge to this non-African site in Israel. Here we evaluate fossil mammals from 'Ubeidiya, which are stratigraphically and directly associated with Early Acheulian artifacts, and find no substantial reason for considering the locality younger than 2Myr, and possibly as much as 500,000 yr older than any record of Early Acheulian artefacts or Homo erectus in Africa."

The truth is that a map of the human genome will not tell us everything. By way of confirmation, we quote the lead paragraph from a recent article in New Scientist: "In the early days of molecular biology, during the 1950s and 1960s, scientists as much as journalists fuelled the euphoria that surrounded the cracking of the genetic code. The secret of life was revealed, so many people thought. As our understanding has grown, however, so has our awareness of our ignorance. Research at the forefront of the molecular sciences has shown that we can no longer regard DNA - the stuff of genes - as a direct and complete set of instructions for the synthesis of proteins. The evidence begins to suggest that messages in the DNA are, in themselves, no more precise than the symbols and sounds with which we communicate. As in the languages with which we are familiar, the correct sense of a message written in DNA seems to depend on the rigorous checking and correction of errors, and on the context in which they are read." The final sentence of the article is really paradigm-shaking: "Thus genetic and evolutionary changes are no longer confined solely to the genome at the pinnacle of a hierarchy of information and control, but reside also in the interplay between DNA and the other components of cells."

Colonies are initiated by solitary fertilized females and, when mature, manifest the three phenomena which characterize eusociality: overlapping generations, cooperative brood care and division into reproductive and sterile (unfertilized) castes. Each colony contains one fertilized and five or so unfertilized adult females, the job of the second group being to deal with predators and to extend and maintain the galleries."

Volcanic vibrations resonated in this chamber and, as the magma pool rose and fell, so did the fundamental tone. Rather than a fixed organ pipe, it was a natural trombone!

Bats navigate by somehow constructing an image of the external world from the echoes of their squeaks. Since bats have but two ears, one wonders how they can develop a three-dimensional image from a two-dimensional sensor; ie., two ears give right-and-left information only. The moustache bat makes up for this deficiency by generating echo-locating pulses at three distinct harmonics: 30, 60, and 90 kilohertz. Its external ears are so shaped that each of these three frequencies has a different acoustic axis, giving the bat in effect three separate sets of ears pointing in three different directions. Inside the bat's head, in the inferior colliculus of the brain, are three sepa rate sets of neurons sensitive to the three different frequencies.

The rocky fragments, according to the prevailing nebular theory, should have condensed early in solar-system history, and then been swept gravitationally into the planet as they were slowed by friction with the uncondensed nebular material. Yet, dark material is still in the rings. (2 ) The incessant bombardment of the rings by meteorites should have pulverized the rings, sending fragments and vaporized material in all directions.

Assuming that these genes mutate at constant rates and working backwards in time, they calculate that animal diversification (i .e ., when chordates diverged from invertebrates) actually began about 1 billion years ago, rather than about 545 million years ago. This expansion of the time frame gives accepted evolutionary processes much more time to innovate and create all those new body plans. The evolutionists are pleased. The paleontologists, however, are in a quandry. They see nothing -- or very little -- in the Precambrian fossil record that substantiates the claim of Wray at al.

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 equal to 7% of the carbon locked up in all terrestrial biota -- animals, trees, grasses, etc. And the Blake Ridge gas hydrates represent a miniscule fraction of the planet's frozen gas hydrates.

"Due to an unknown cause, certain of the prints once labeled human are taking on a completely different character. The prints in the trail which I have called the 'Taylor Trail,' consisting of numerous readily visible impressions in a left-right sequence, have changed into what appear to be tridactyl (three-toed prints, evidently of some unidentified dinosaur. The changes in the impressions themselves are mostly confined to lengthening in the downriver direction. The most significant change, however, is that surrounding the toe area. In almost each of the prints in the trail, three large 'toes' have appeared, similar to nearby dinosaur tracks. These toes, typically, are coloration phenomena only, with no impressions, in most cases. Frequently the 'mud pushup' surrounding the original elongated track is crossed by this red coloration. The shape of the entire track, including both impression and coloration, is unlike any known dinosaur print." J. Moore, the author of this article and a creationist, suggests that creationists no longer use the Paluxy tracks as evidence that humans and dinosaurs once coexisted.

Normally, the magnetometer scans each cell as the cell moves horizontally beneath the magnetometer. During one run, the researchers left the cell in a single position for a long time while the magnetometer was still on. After 20 minutes or so, the magnetic field strength began to drop. 'It was very dramatic to watch this field collapse,' says MacVicar. After about a minute at zero, the magnetic field grew larger again but in the opposite direction."

Since host species may eject parasite eggs or fail to nurture parasite chicks, brood parasites have evolved mimicry as a powerful weapon in these battles. Mimicked are host eggs, host nestlings, and host vocalizations. But the most insidious weapons of all involve the outright murder of host chicks. To this end, parasite chicks have evolved some special weapons and behaviors. Some cuckoo chicks evict host eggs or chicks by squirming under them and positioning them in a specially configured hollow on their backs. Then, pushing upward and outward to the rim of the nest, they dump their cargo over the edge. Other brood parasites are more direct and bloodthirsty.

... I saw constellations low in the southern sky that I'd only seen on star charts). "On the occasion of the six-hour storm (which started about eight thirty in the evening), whenever the rain abated, we went outside and watched. "During a total of approximately 1 hour of watching, I observed phenomena I had never (consciously) seen before. Following ground strikes (probably over the horizon), on at least eight occasions, the ground end of the strike (i .e ., on the horizon) would be glowing for anything up to thirty seconds. "On one particular occasion, my brother was recording the proceedings with a camcorder. I saw a big ground strike followed by a glow on the horizon. I was trying to direct him to that spot, when there was another ground strike 5-10 degrees to the right of the glow; then, maybe a second later, the original glow erupted into a brilliant point of white light that lit up the sky. "I was gratified to find that we had this captured on video, although the glow from the first strike can't really be seen. "Does anyone know what we were seeing here? Has anyone seen either of these phenomena close at hand?" From Science Frontiers #91, JAN-FEB 1994 . 1994-2000 William R. Corliss ...

... way to the horizon. It was as if the plane was running on an aerial railway. I think it significant that only two of the planes showed this phenomenon as I suspect it was heightdependent. At this time the sun was high and shining from the south-southwest." J.O . Mattsson, Lund University, surmised that the black streaks in front of aircraft were shadows of the condensation trails behind the two planes. The shadows were cast forward ahead of the planes upon the hazy, though cloudless, atmosphere above the ocean. (Evans, Alun; "Condensation Trail Shadows," Weather, 53:371, 1998.) Comment. Since the sun was high in the sky, it is difficult to visualize how a the vapor-trail shadow could be cast directly ahead of the aircraft. Hummm! We suppose that the vapor trails acted like those sunset clouds that produce crepuscular rays. The geometry, though, is a bit different. Digitized sketch of contrail phenomenon. Apparently, the contrail's shadow was projected on the misty atmosphere ahead of the aircraft. From Science Frontiers #123, MAY-JUN 1999 . 1999-2000 William R. Corliss ...

That this was no ordinary meteor is born out by several curious data: Tree-rings in the area show an enormous acceleration of growth since 1908; Inhabitants of this remote region stated that the reindeer suffered from mysterious scabs in 1908; There is a slight but definite increase in the radioactivity of the surviving trees; and Testimony indicates that the me-teor changed direction twice before impact. The various theories of what really happened, from black hole to nuclear explosion, are listed without comment. (Rich, Vera; "The 70-Year-Old Mystery of Siberia's Big Bang." Nature, 274:207, 1978.)

... room." Three to five weeks later, the envelopes came back to Grattan-Guinness in the regular mail. Many were posted at offices with colorful names, such as Carefree, AZ, and Deadwood, SD. After examining the envelopes for signs of tampering, Grattan-Guinness opened his mail. The enclosed sheets of paper contained answers to his questions. Often the responses were vague -- like those given by mediums and oracles. Occasionally, the envelopes contained extraneous objects, even sheets with questions posed by other SORRAT members during this extensive experiment. Who provided the answers found in the returned letters: the communicators! Grattan-Guinness explained. "The most positive and insistent responses from the communicators, apparently also to many other correspondents and even in response to questions which are not directly relevant, are that they are the surviving residues (my word) of dead persons, and that they operate independently of our restrictions of space and time. For example, 'Remember that Our Side is vast in space, and outside physical/temporal dimensions, and many are here!'" (Grattan-Guinness, I.; "Real Communication? Report on a SORRAT LetterWriting Experiment," Journal of Scien tific Exploration, 13:231, 1999.) Comment. We have summarized a 26-page report complete with photos, tables, etc., published in a peer-reviewed journal published by the Society for Scientific Exploration, which is composed mainly of diploma-holding scientists. Of course, mainstream science journals wouldn't touch SORRAT with a 10meter pole ...

Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects More Nominative Determinism Following in the trail of Feedback's page in the New Scientist, we herewith offer two more cases of nominative determinism or ND. This phenomenon, as readers of SF are well aware, occurs when a person's last name is related to his or her occupation. A solid example of ND is seen in the name of the Director of U.S . Programs for the Rodale Institute. The Institute, it turns out, is studying carbon and nitrogen balances in organically managed cropping systems. Nitrates originating in such agriculture contaminate the ground water and often end up in drinking water. The EPA has determined that nitrates in drinking water can be harmful; thus this study. Who directs the study? Dr. Laurie Drinkwater! (Anonymous; "Organics Reduce Groundwater Pollution," Acres U.S .A . , p. 11, May 1999. Cr. L. Cortner.)
