In this vein, K. Fabian writes about an interesting inconsistency: "In the early 17th Century, Galileo discovered that the planet Mars goes through a minor gibbous phase. Even in its maximum gibbous phase, Mars is 88% illuminated. Quoting James Muirden in the Amateur Astronomer's Handbook, 'It is remarkable that Galileo was able to make out the phase with his tiny telescope.' "Even more amazing, in my opinion, is that Galileo, while he was able to resolve the slight phase of Mars, was unable to resolve the major ring around Saturn. Mars is a difficult object in a small telescope, while Saturn is easily resolved as a ringed planet in even a 40-mm spotting scope at 30X. Why did the rings of Saturn elude Galileo, while the more difficult Martian phases did not? Perhaps at the time of Galileo the rings of Saturn were much more difficult to observe than they are today." (Fabian, Karl; personal communication, September 9, 1988.) Reference.

We will not comment on the reincarnation bit, but it does seem that S. Devi's remarkable capabilities are somewhat different from those of Ramanujan. The latter intuitively saw mathematical relationships as expressed in equations and identities; Devi is a mental calculator of no mean talent. In 1977, Ms. Devi beat a UNIVAC 1108 computer to the 23rd root of a 201-digit number. The machine, which required two hours to program for the task, took more than a minto solve the problem. She took 50 seconds. "And, in 1981, she made the Guinness Book of World Records as the 'Human Computer' by correctly multiplying two 13-digit numbers -- 7,686,369,774,870 times 2,465,099,745,779 -- in 28 seconds.

The thick haze reduced atmospheric transparency, but the seeing was excellent. The infamous canals were there! "Two canals stretched clearly from Sabaeus Sinus and Meridiani Sinus to the northern deserts, where they faded.

Chyba has examined the lunar impact record and derived an estimate of the total mass of objects impacting the moon during the (hypothetical) period of heavy bombardment 3.8 to 4.5 billion years ago. This allowed him to calculate the mass influx for the earth during this period. His conclusion: if only about 10% of the incoming mass consisted of comets (mostly ice), the earth would have acquired all its ocean water. (Chyba, Christopher F.; "The Cometary Contribution to the Oceans of Primitive Earth," Nature, 330:632, 1987.) Comment. Frank claims that the earth today is continually bombarded by small icy comets, which down the eons may have kept the ocean basins full.

Such survival is contrary to all mainstream thinking. Thus, when a datum comes along, even though it appears rather far-fetched, that testifies for the recent survival of mammoths, we must at least examine it. The datum in question (and it really is questionable) comes from the The Na tional Tombstone Epitaph , hardly part of the scientific literature! The article develops the theme that Chinese explorers landed in North America several millennia ago. The basis for such speculation is an ancient Chinese work called the Shun-Hai Ching , which is reputed to be about 3500 years old. In it, the Chinese explorers mention encounters with several strange animals. One is easily recognized as the collared peccary, known only in the New World, thus establishing the reality of a transPacific contact. Now, here is the piece de resistance: "Here we met a creature as tall as three men and so great that the earth trembled as he walked. He had a voice as loud as thunder. He was red like fire.

(See his book Diseases from Space .) In yet another book, Evolution from Space , he goes further, stating that the evolution of terrestrial life can also be affected by the extraterrestrial inoculation of genetic material. But, just maybe, influenza pandemics are due to pigs! Every 10-20 years, new flu viruses seem to crop up against which humans have little resistance. The latest theory is that there exists a human-duck-pig connection. It seems that human flu viruses can multiply in ducks, but are not transmitted among ducks. It is also likely that duck viruses multiply in humans, but are not transmitted from one person to another. But enter the pigs: "There is firm evidence that pigs can become infected by and may transmit both human and avian influenza viruses not only amongst other pigs but also back to the original hosts. Therefore, pigs seem to be 'mixing vessels' where two separate reservoirs meet and where reassortment between avian and human influenza A viruses occurs, giving rise to the antigenic shift by creating new human pandemic influenza strains with new surface antigens."

Because the subject of the consciousness experiment is living, we expect strings of baseline velocity and vector data which are, at some level, inextricably time-variant. This complicates the statistical procedures which must be used to analyze the data. "This paper examines the variation in baseline data strings, and describes two alternative statistical procedures which have been used to determine the probability of consciousness effects. Two levels of control are applied, allowing global comparison of frequency distributions of experimental scores with similar distributions derived artificially from baseline data. In both cases the null hypothesis is that there is no psi effect. The data quite strongly suggest the rejection of the null hypothesis, although the distributions of run scores contain several values beyond 3 sigma and are nonnormal.

We found a significant departure from the inverse-square law, asymptotically approaching -547 36 microGal at the top of the tower.

Be this as it may, let us see what Frohlich has to say about deep-focus earthquakes. Why are they anomalous? Can't quakes occur at any depth in the earth? No! Because below about 60 kilometers, the rocks should be so hot that they become ductile; instead of breaking catastrophically under stress, they just deform or "flow." It would appear, then, that conditions for earthquakes do not exist below 60 kilometers.

Their sketches of what they saw are shown in Fig. l. Although their descriptions differ slightly, they agree that the 'missile' had a black band around its centre. They watched the object for a period of between 0.5 min and 1.5 min (period uncertain). It was first seen almost due north and it disappeared in the west-northwest. No noise was heard." No one else reported seeing the object. A real missile was considered very unlikely. However, the object appeared in the direction of the glide path of the Edinburgh airport, where two aircraft had landed at about the time of the sighting. The witnesses were adamant that the UFO did not look at all like a plane; and that it was much higher in the sky than planes on normal glide paths, which were to be seen just above the horizon between the houses.

R.G . Jahn, the leader of the Princeton group, terms the research "Engineering Anomalies Research." This title is apparently more palatable to mainstream science than "Mental Influence on Electronic Devices" or "Affecting Cascading Spheres with Thought Waves." Nevertheless, most of the experimental work is in these two areas. As parapsychological research goes, the Princeton work is of the highest scientific quality. In the first category, subjects (called operators in the report) were asked to influence the pulses produced by a Random Event Generator (REG). The REG was actually an electronic noise source coupled with circuits that created random positive and negative pulses. The operator mentally tried to increase or decrease the number of counts, or generate baseline data for experiment control. After 33 different operators and over 250,000 trials, there appeared a small but statistically significant indication that the operators were actually able to influence the equipment. Also interesting is the fact that each operator had a private "signature"; that is, individual cumulative deviation graphs (like the one shown) had typical shapes for each operator.

Compared to the purported age of the solar system, 4.5 billion years, Saturn's C-ring (and perhaps the other rings, too) is a brand-new feature. Where did it come from?

Now it seems that they may have been a bit hasty and all-encompassing. Not that the Velikovsky scenario is correct or that Mars might at any moment depart from its present orbit, but rather that astronomers must now admit an inability to predict planetary motion over billions of years - even tens of millions of years! For the solar system, if those ubiquitous computers are correct, is not a well-behaved family of planets. J.

Their research in the decade following the Mars landings has only strengthened their belief. Further, they have demonstrated that one of the other life-detection experiments producing negative results was not sensitive enough to detect low population levels of microorganisms.

From a dayglow experiment aboard NASA's satellite DE-1 (Dynamic Explorer-1 ) comes an unexpected discovery of considerable potential importance. Looking down on the earth, the DE-1 records the light emitted by atmospheric oxygen at altitudes of about 200-300 kilometers -- this is the so-called "dayglow." The experimenters, L. Frank, J. Sigwarth, and J. Craven, all at the University of Iowa in Iowa City, have found that their dayglow images are speckled with transitory dark spots. "According to Sigwarth, each hole expands like a drop of dye spreading out in a glass of water; within about 30 seconds the dayglow intensity drops by about 95 percent over an area of about 3,000 square kilometers. Then, over the next 3.5 minutes, the dayglow intensity increases toward its normal value as the hole grows to an area of about 25,000 km2 ." The Iowa group thinks that the holes or spots are created by meteors hitting the upper atmosphere because the spots follow the same time distribution as meteors. For example, they are more frequent during the well-known meteor showers. The theory is that the dark spots are formed when ice associated with the meteors is turned into water vapor, which reacts with the atmospheric oxygen producing the dayglow, in effect removing temporarily part of the light ...

The clues seem to reside in extrachromosomal DNA that carries drug-resistance-conferring genes from one cancer cell to another. Cancer cells dying from chemotherapy may, for example, cast off extrachromosomal DNA that carries information on how to combat the chemicals. Other factors may also be at work, but basically we have only suspicions. (Silberner, Joanne; "Resisting Cancer Chemotherapy," Science News, 131:12, 1987.) Comment. Insects and other organisms also acquire resistance to chemical poisons. Does extrachromosomal DNA play roles in these instances, too? Can Information coded in extrachromosomal DNA be passed from one species to another, say, via insect bites? From Science Frontiers #50, MAR-APR 1987 . 1987-2000 William R. Corliss ...
