About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.


Subscriptions to the Science Frontiers newsletter are no longer available.

Compilations of back issues can be found in Science Frontiers: The Book, and original and more detailed reports in the The Sourcebook Project series of books.

... been debating a concept that is fundamental to our understanding of how cells evolved. It is the proposal that some of the structures that are found in the larger cells of animals, plants and fungi (eukaryotic cells) are the descendants of simpler bacteria-like organisms (prokaryotic cells) that had at some stage entered into an intracellular existence, or endosymbiosis. The idea is not a new one, but only in the light of modern experimental evidence has it become acceptable to many biologists. If the hypothesis is correct, then virtually all the major groups of familiar organisms originated 'suddenly' through endosymbiotic associations." Following this lead paragraph, with its paradigm-shaking final sentence, are three pages summarizing the biological evidence favoring evolution by endosymbiosis. (Kite, Geoffrey; "Evolution by Symbiosis; The Inside Story," New Scientist, p. 50, July 3, 1986.) Comment. We cannot possibly do justice to this exciting idea of evolution forced by the uniting of different organisms in the limited format of Science Frontiers. Instead, we encourage readers to purchase a new book by L. Margulis and D. Sagan (son of Carl Sagan and L. Margulis) entitled Micro Cosmos. In passing, we must also remark on the obvious relationship of endosymbiosis to F. Hoyle's "evolution from outer space." Hoyle believes that microorganisms and other biological information are transported in cosmic debris. Finally, the story of Lynn Margulis' uphill fight against scientific skepticism is related in: (Keller, Evelyn Fox; "One Woman and Her Theory, ...

... , just as they defend the Croton plant from its enemies. Player 3. The caterpillars, though seemingly benign, are the heavies in this menage-a -trois! They get both leaves and nectar from the plant for nothing. They do supply the ants with nectar in exchange for protection, but subtle subversion prevails here! First they attract the ants with their songs; then, they seduce them with nectar that is much more nutritious and attractive than that produced by the Croton plant. Finally, they chemically force the ants into defensive postures against predatory wasps by spraying them with a mesmerizing substance from special "tentacle organs" near their heads. Why is all this subversive on the part of the caterpillars? It appears that the caterpillars have invaded and undermined the normal ant-plant symbiosis -- a very common, mutually beneficial arrangement. The ants have been seduced into letting the caterpillars feast on the Croton plant, although the ant-plant compact originally required that the ants repel all herbivorous insects. What makes this tale of subterfuge so remarkable is that the caterpillars had to evolve three separate organs in order to accomplish it: (1 ) their vibratory papillae; (2 ) their nectary glands; and (3 ) their mesmerizing tentacle organs.
