... amount of aluminum-26 (26Al) in the interstellar medium." Instruments on satellites (gamma-ray spectrometers) have detected so much aluminum-26 that radical hypotheses seem required. The problem is that aluminum26 is radioactive with a half-life of only about 1 million years -- a very short time astronomically speaking. The aluminum-26 cannot be primordial solar-system stuff; it cannot even be 10 million years old. It had to be created somewhere nearby recently. The best aluminum-26 factory conceived so far is a nova in our vicinity. (Anonymous; "Are We inside a Supernova Remnant?" Sky and Telescope, 69:13, 1985.) Comment. A nova close enough to engulf the earth with its debris must have had a profound effect on the earth and its cargo of life -- perhaps on Saturn's rings, too. See next item .

... and being easily formed into any shape." Such PK 'parties' have been held scores of times since 1981, leaving trails of damaged kitchenware and popped soy beans. It's all a lot of fun. The people attending "feel good" about themselves and their shared experiences. (Houck, Jack; "PK Party History," in Proceedings of a Symposium on Applications of Anomalous Phenomena, C.P Scott Jones, ed., Kaman Tempo, Alexandria, Virginia, 1984.) Comment. Is mass delusion the foundation of PK parties? Is the above article serious? Houck's paper is in a long collection of rather standard parapsychological fare presented at a conference held under the auspices of Kaman Tempo. The phenomena of PK parties are similar to the audible effects produced by a Toronto group a few years ago. In their case, the participants conjured up "Phillip, the Imaginary Ghost," who communicated via table rapping. In all such group efforts, including the classical seance, there is strong psychological involvement. Skeptics do not do well at PK parties.

... Online All Issues This Issue Sourcebook Project Sourcebook Subjects A Different Way Of Looking At The Solar System The current scientific consensus has the sun and its planets forming during the same process of accretion/condensation. In this view, the inner terrestrial planets differ from the outer giant planets only because their volatile elements were driven off by the sun's heat. This scenario has many problems, as recorded in our catalog volume The Moon and the Planets. G.H .A . Cole thinks that astronomers might have more success in explaining the origin of the solar system if they considered it a system of five large bodies of star stuff (light elements), each surrounded by its own retinue of high density satellites (the sun's four satellites would be the inner planets). In effect, then, we would have a quintuple star system in which only one member (the sun) collected enough star stuff to make it to incandescence. The four, large, outer planets would be merely failed stars. The advantages of this change of perspective are threefold: (1 ) All five central bodies are now compositionally similar as a class, (2 ) In each of the five systems, the angular momentum of the central body is greater than that of its satellites, whereas in the unitary solar system the angular momentum of the nine planets is much greater than that of the sun -- an embarrassing anomaly. (3 ) A final "bonus" appears when the distances of the satellites in the five systems are plotted, as indicated, and compared. The arrangement ...

... butterflies were discovered to sport photoreceptors on their genitalia. These I are used during mating to confirm the position of the female's ovipositor.(Arikawa, Kentaro; "Hindsight of Butterflies," BioScience, 51:219, 2001.) Barn-Owl auditory neurons multiple signals. Barn Owls can locate rustling mice in the dark with high precision. They discern their prey by sound rather than light. To achieve the high accuracy needed to home in on small rodents in the black of night, their ears are slightly offset so that they can draw a bead by using microsecond time-of-arrival differences in the sounds coming from the target. To increase the owl's passive sonar, their auditory neurons multiply the signals instead of adding them as do other neurons. In effect, they create an "auditory map" of their surroundings. On their high-precision auditory maps, a rustling mouse would be highlighted. So far, though, biologists have not learned how neurons can multiply signals. The asymmetrical design of the Barn Owl's ears is essential for pinpointing its prey in the dark.

... a mental image or a deified thought but an actual voice heard when one was presented with a situation requiring decisive action." You must really read Jaynes' book to appreciate the evidence he has collected in support of his hypothesis. In the present article, J. Hamilton has found additional support for Jaynes' theory. His abstract follows: "When a system for communicating with nonverbal, quadriplegic, institutionalized residents was developed, it was discovered that many were experiencing auditory hallucinations. Nine cases are presented in this study. The 'voices' described have many similar characteristics, the primary one being that they give authoritarian commands that tell the residents how to behave and to which the residents feel compelled to respond. Both the relationship of this phenomenon to the theoretical work of Julian Jaynes and its effect on the lives of the residents are discussed."

... but it now appears that there is a complementary mode of communication that relies upon chemistry rather than electricity. While the fastest way to transmit signals in the brain seems to be along the neurons and across their points of contact, the synapses, other signals may travel -- a bit more slowly -- by what is termed "volume transmission." Volume transmission is like broadcasting radio waves in three dimensions, except that in the brain the radio waves are replaced by the diffusion of chemical signals. L.F . Agnati et al explain: ". .. our experiments have shown that neurons also release chemical signals into the extracellular space that are not necessarily detected by neighboring cells but by cells far away, in the same way hormones released by a gland into the bloodstream can have effects on cells far away. These processes occur on much longer time scales than does synaptic transmission, and they probably play a distinct role, perhaps regulating the brain's responses to synaptic signals. .. .. . "We might speculate that volume transmission is involved in the neuroendocrine system and the central autonomic system. Changes in the activity of the brain during sleep and wakefulness, relative levels of alertness, mood and sensitivity to pain may be highly dependent on volume transmission. Thus, although information regarding to location of pain is carried by the circuitry of the nervous system, the intensity and duration of the pain may be somewhat modulated by the ambient homoral signals. In this respect, acupuncture may also be a phenomenon that is dependent on volume transmission." (Agnati, Luigi ...

... several mutations and a slight change in gene frequency for one or two loci, all occurring in a limited period of time. "If an organism such as the Kaibab squirrel is able to escape all but a few minor changes in coat color (and these of dubious survival value) given the supposed immense time of rather complete isolation and violation of the Hardy-Weinberg equilibrium, we must ask wherein lies the fault. Is it in the violation of the Hardy-Weinberg concept, or is it in the time alloted for gene pool changes to occur?" Meyer answers his questions by stating that the Hardy-Weinberg equilibrium concept seems reasonably well-founded, so that the problem must lie in the length of time estimated for the Kaibab squirrel's isolation from surrounding populations. In effect, Meyer concludes that the Grand Canyon is much younger than generally supposed. (Meyer, John R.; "Origin of the Kaibab Squirrel," Creation Research Society Quarterly, 22:68, 1985.) The Kaibab squirrel is isolated in the Kaibab Plateau (60 x 35 miles in extent). South of the canyon and elsewhere, the similar Albert squirrels may be found.

... , Mark D., and Lu, C.C .; "Sex in Giant Squid," Nature, 389:683, 1997.) The free-style penis. In the octopus and many cephalopods, the males have a special tentacle with which they insert their spermatophores under the mantle of the female. The tentacle is then retracted for future use. The male paper nautilus is more profligate with its tentacles. The paper nautilus is cephalopod which, like its cousin, the chambered nautilus, "sails the unshadowed main."* When the male detects a receptive female, he avoids intimacy. It's sex at a distance. His spermatophore-bearing tentacle detaches itself from the body and swims -- under its own power -- to the female, being in effect a swimming penis. Just how this peculiar arrangement evolved is anyone's guess. Perhaps it has something to do with the fact that the female paper nautilus still retains a molluscan shell, while the male has lost this armor and looks more like an aspiring octopus. Without a shelly defense, the male may not want to get too close to the female! (Anonymous; "The Shell of Aphrodite," Nature, 391:550, 1998.) *Apologies to Oliver Wendell Holmes for using his words in this racy context.

Conwy, Wales. Here is carefully observed case of ball lightning with rather spectacular side effects. Mrs. P. Stafford was looking through her front window: ". .. when she saw what she first thought was a 'ball of white fire', larger than a football, about 20 to 30 feet from her, travelling horizontally at a constant height up her drive. There was very heavy rainfall, perhaps with some hail, but no lightning or thunder. The ball was seen against the background of other houses and her view of it was not interrupted. It was round, opaque and predominantly white with some yellow, and surrounded by a blue, irridescent halo. She said it was reminiscent of a meteor or comet and the light from it was like that from a fluorescent tube. It was bright enough to be clearly visible in daylight and appeared to be spinning or rotating. It hit the oak tree, perhaps 12 or 13 feet away, in Mrs. Wignall's front garden, with a terrific crack and explosion. "The ball was in sight for about 10 to 15 seconds, and its appearance did not change until it struck the tree, whereupon it became smaller. It hit the trunk about half way up and split the bark and trunk, showering splinters of wood over a distance of about 50 yards. As it did so, it ...
