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

Subscriptions to the Science Frontiers newsletter are no longer available.

... This Issue Sourcebook Project Sourcebook Subjects The failure of two-dimensional life The fossil record tells us that just prior to the Cambrian explosion of life, the earth was populated by a diverse assemblage of soft-bodied, shallow-water marine invertebrates, some with dimensions as large as 1 meter. This whole group of animals did not survive into Cambrian times, thus ending what has been termed The Ediacaran Experiment. Some paleontologists have tried to find similarities between the Ediacaran and Cambrian life forms to preserve the continuity of life. This has proved difficult, and some scientists now feel that The Edicaran approach to "largeness" was to increase surface area externally. The Ediacarans were therefore shaped like pancakes, tapes, fans, etc. This enabled them to present large areas to the environment for respiration ... feeding, and other biological functions. In contrast, many present life forms achieve "largeness" by increasing internal areas, as in the lungs, folded intestines, etc., along with the forced circulation of air, blood, and other sub stances. This latter approach survived, while the two-dimensional Ediacaran Experiment did not. The demise or extintcion of the Ediacarans led Gould, the author of this far-ranging article, to the influence of extinctions on life in general -- a hot topic these days. Gould stated that with natural selection operating, one would expect continual "improvement" in life forms, but that this had not happened. "I regard the failure to find a clear 'vector of progress' in life's history as the most puzzling fact ...
