Several experiments in deep mines and tunnels seem to have registered proton decays. Is nothing stable anymore? There is hope. A huge cubical detector, 21 meters on a side, is now operating 2000 feet under Lake Erie in a salt mine. The water-filled cube is monitored by 2048 photomultipler tubes, and is serviced by divers! After 80 days of operation, no events resembling proton decays have been detected, whereas many would have been expected if the other reports were true. The GUTs may be in trouble; and there may be something stable in the universe that we can count on! (Thomsen, D.E .; "Decay-Resistant Protons in Ohio," Science News, 123:85, 1983.) Comment. See SF#14 for some of the strange particles detected in the Kolar Gold Fields, in India, where some of the supposed proton decays were reported.

Science Frontiers ONLINE No. 118: Jul-Aug 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Two Creations Of Life?The lifeforms called Archaea and Eubacteria follow radically different life styles. The former are very happy in such extreme environments as the salty Dead Sea and the sea-bottom, hydrothermal vents; the latter prosper in bad hamburgers and your gut. Despite their differences, they have always been thought to have evolved from a common ancestor. A more subtle, fundamental difference has now been found. Recall SF#117 and how some terrestrial life forms do incorporate right-handed molecules in their structures, especially in cell membranes? The ubiquitous Eubacteria do this. In the Archaea, however, the same structural components of the cell membranes (glycerophosphates) are left-handed. A subtle difference, but one with deep implications. Some scientists maintain that it is impossible for two organisms relying upon mirror-image versions of the same molecule to have evolved from a common ancestor. Their genomes must be fundamentally different. Conclusion: the Archaea and Eubacteria must have evolved separately, and from different biological wellsprings -- that is, "creations." Such thinking is anathema. M. Kates, a Canadian evolutionary biologist, is skeptical. "Both the physics and chemistry of membranes are so complex that I would regard it as highly improbable that they could have auto-assembled twice."

Fujita, of Tokyo's Medical and Dental University, was studying tropical diseases in Borneo, he was amazed to discover how remarkably healthy the children were, despite the heavy loads of parasites they carried. Fujita asked himself what seems like a ridiculous question: Could some parasites actually promote good health? Ensnared by this thought, he tested the idea by introducing a tapeworm into his own gut. Both Fujita and tapeworm did well. So well, that Fujita now hosts four thriving tapeworms! Fujita wonders why his colleagues are not interested in his experiment. They don't invite him to their meetings anymore. (Anonymous; New Scientist, p. 116, New Scientist, February 24, 2001.) From Science Frontiers #135, MAY-JUN 2001 . 2001 William R.

Science Frontiers ONLINE No. 20: Mar-Apr 1982 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A TALE OF TWO ECOSYSTEMS -- OR MAYBE MANY MORE Comment. It was quite fortuitous that the following two pieces, found on the same day, fit together so nicely. (Nature is fortuitous!) A group of scientists studying termites have isolated over 100 species of protozoa and bacteria living cooperatively inside the termites gut. Some of the bacteria even live inside the protozoa and other bacteria forming ecosystems of several symbiotic levels within each termite. Each termite itself is part of a complex social "superorganism," the termite colony. That termites had bugs in-side them has long been known; but the new-found complexity and interdependency of life systems within life systems is remarkable. The researchers believe that the life forms inside the termite work together to create the uniform internal environment needed by all inhabitants, just as the termites themselves cooperate to maintain a favorable environment inside their hill. (Anonymous; "And Littler Bugs Inside 'Em," Scientific American, 246:78, February 1982.) The termites, though, are only part of a much larger ecosystem, the earth itself. J.E . Lovelock, in his Gaia, A New Look at Life On Earth, has observed that our planet's environment has actually changed little down the eons despite solar variations. Lovelock's hypo thesis is that all terrestrial life -- animals, plants, termites, etc -- work sym biotically ...

... Science Frontiers ONLINE No. 33: May-Jun 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Rubberneckia The long-standing belief that unlimited rotary motion is impossible in animals has been shattered. It was, after all, a very reasonable assumption, because necks and other appendages turn only so far before bones and muscles begin to snap. Well, it seems that inside ter-mite guts there resides a single-celled animal with a head that rotates constant-ly 30 times a minute. Since none of its membranes shear during rotation, we must infer that membranes are basically fluid structures rather than solids as supposed. The animal, called Rubberneckia, has a shaft running the full length of its body plus a motor of undetermined character. To make Rubberneckia even more bizarre, thousands of tiny, rod-like bacteria occupy long grooves on the cell's surface. Like galley slaves, the bacteria row with their flagella to keep Rubberneckia moving -- a curious symbiotic relationship.

Strange tube worms up to six feet long have been discovered off the Spanish coast, dining on the hydrogen sulphide from rotting beans [beams?] in the hold of a ship that sank 13 years ago. Lacking mouth, gut and anus, they rely on bacteria to process the nutrients in minerals and dissolved in sea water. They had been found previously in the Pacific and the Gulf of Mexico. It was thought they liked to live in huge colonies around cracks in the ocean floor where hot, mineral-rich lava pours out and areas where oil and gas leak from the seabed."

Science Frontiers ONLINE No. 14: Winter 1981 Supplement Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Worms with inside-out stomachs The recently discovered tube worms, living near the hot water vents on the ocean bottom off the Galapagos, have no mouths or guts. Their bodies are covered with thousands of feathery tentacles, each packed with blood vessels. Apparently, the tube worms extract nutrients directly from the sea water and expel wastes the same way -- having in effect external stomachs. These worms, which may be many feet long, contain enzymes that permit them to extract carbon dioxide from the seawater and fix it much like plants do during photosynthesis. George Somero, at Scripps, estimates that the enzyme levels in the worms are similar to those in a spinach leaf. (Anonymous; "15-Foot Sea Worm Has Plant Qualities," San Diego Evening Tribune, May 22, 1980. UPI dispatch) Comment. This curious biological anomaly developed in an ecological niche where the primary energy source for sustaining life is geothermal rather than solar. How did this remarkable situation arise? Do the tube worms have relatives in the fossil record showing a step-by-step development of inside-out stomachs? From Science Frontiers #14, Winter 1981 . 1981-2000 William R. Corliss ...

But the dilemma of the New Synthesis is that no one has satisfactorily demonstrated a at the population genetic level by which innumerable very small phenotypic changes could accumulate rapidly to produce large changes: a process for the origin of the magnificently improbable from the ineffably trivial. This leads to skepticism about the microevolutionary approach. Perhaps, as Waddington put it: 'the real guts of evolution -- which is, how do you come to have horses and tigers, and things -- is outside the mathematical theory.'" Did you guess a creationist publication? Sorry! (Thomson, Keith Stewart; "Macroevolution: The Morphological Problem," American Zoologist, 32:106, 1992.)
