To the researchers' surprise, this instrument detected sudden appearances of clouds of sodium atoms at about 85 kilometers altitude. The clouds quickly dissipate, but where do they come from? The best guess is that their source is meteors vaporizing in the upper atmosphere. (Raloff, Janet: "Sudden Sodium Surges Seen over Illinois," Science News, 134: 238, 1988.) Comment. Could these sodium clouds have any connection with the controversial icy comets? From Science Frontiers #61, JAN-FEB 1989 . 1989-2000 William R. Corliss ...

... in aquatic mammals. Some of these are: position of fetal hair, loss of body hair, subcutaneous fat, face-to-face copulation, weeping, etc. The combination of hairlessness and subcutaneous fat seems almost totally confined to aquatic mammals and humans. Two other characteristics are covered in some depth in this article: The discovery that some prehistoric shell middens consist of deep-water shellfish, which must be the result of breath-held diving. This human skill, again unique among primates, is obviously quite ancient. Furthermore, recent experiments suggest that in humans, in addition to seals and ducks, vascular constriction is not limited to the arterioles but extends to the larger arteries, too. This indicates some degree of specialized adaptation to a diving life. Most animals with a sodium deficiency display an active craving for salt which, when satisfied, disappears. In humans, salt intake has little or no relation to the body's needs. Some Inuit tribes avoid salt almost completely, while people in the Western world consume 1520 times the amount needed for health. In other works, a single African species (assuming humans have an African origin) possesses a wildly different scheme of salt management. Humans are also the only primates to regulate body temperature by sweat-cooling, a system profligate in the use of sodium. Proponents of the Aquatic Ape Hypothesis believe that sweat-cooling could not have developed anywhere except near the sea where diets contain considerable salt, in fact much more salt than the body requires. This article also deals with certain skeletal features of early ...

Science Frontiers ONLINE No. 136: JUL-AUG 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Are We Merely Fancy Crystals?Just about everyone will concede that when sodium and chlorine atoms arrange themselves to build salt crystals that they are simply obeying the well-known laws of physics. In other words, salt crystals are "natural." "Intelligent design" need not be invoked in explaining their existence. This is OK for salt crystals but can we say the same for biological forms such as proteins and, ultimately, human beings? Are these more complex biological forms also natural; that is, reducible to and explainable by the laws of physics? Human beings certainly seem irreducible; and some proteins are so large and complex that one is unsure that physics is up to the task of explaining these tangled structures consisting many hundreds of atoms. Some of these doubts have been relieved by recent advances in protein chemistry. It appears that the different types of protein folds, which number in the thousands, can be classified and sorted into distinct structural families -- just like the much simpler crystals of salt, quartz, galena, etc fall into orderly classes. The clear implication is that protein folds and, by extension via further research, the protein molecules themselves, are also natural and reducible just like the salt crystals. If proteins are natural, perhaps even more complex biological forms are also, and so on up the complexity ladder to viruses (which often look like crystals through the microscope), bacteria, and ...

... Science Frontiers ONLINE No. 100: Jul-Aug 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Has jupiter flashed before?Well, not Jupiter itself but its strange Galilean satellite Io. On July 26, 1983, Io suddenly brightened by about 50% for just under 2 minutes. The "flash" represented an emission of energy of some 1028 ergs, which is equivalent to the impact on the satellite of an ice mass 5-kilometers in diameter moving at 60 km/sec. This collision interpretation is encouraged by the 1994 impacts of cometary fragments on Jupiter proper. In the case of Io, however, there is another possibility: electrical arcing. Io's volcanoes are prodigious spewers of metallic sodium, and T. Gold has speculated that colossal arcs may occur in this conducting environment as Io cuts through Jupiter's magnetic field. (See Science Frontiers #10. (O 'Brien, Roger; "Has Jupiter Flashed Before?" British Astronomical Association, Journal, 104:6 , 1994.) Comment. Io is also noted for its erratic brightening after it emerges from Jupiter's shadow. For more on Io's so-called "post-eclipse brightening," see p. 67 in the book Science Frontiers and the catalog volume The Moon and the Planets, both described here .

... This synchronism suggests some sort of energy interchange between Io and the top of Jupiter's atmosphere. The theory now in vogue states that Jupiter's rotating magnetic field induces a voltage across 2300-mile-diameter Io, resulting in an electrical current of some 5 million amperes flowing between Io and Jupiter, some 262,000 miles away. In this bizarre electrical circuit, the two moving "terminals" on Jupiter, in the northern and southern hemispheres, are heated by the current flow and show up as fuzzy infrared-bright spots. (Cowen, R.; "Jupiter and Io: Infrared Spots Mark Link," Science News, 144: 325, 1993.) Comment. In passing, it should be remarked that Io is mantled by a cloud of electrically conducting sodium vapor. A weird moon in other respects, too, Io occasionally casts double shadows on Jupiter's upper atmosphere during transits. See AJX4 in The Moon and the Planets. In addition, in AJX2, infrared-hot shadows of the satellites Ganymede and Europa are mentioned. Very strange! To order The Moon and the Planets, visit here .
