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.

Science Frontiers ONLINE No. 55: Jan-Feb 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Sardinia's prehistoric towers Sardina is home to an immense population of mysterious prehistoric stone towers called "nuraghi." (Singular form is "nuraghe.") Over 7,000 of these remarkable dry-stone edifices exist -- a concentration of monumental stone architecture unparalleled in Europe. "' Nuraghe' derives from the prehistoric Sardinian root 'nur' which means both 'hollow' and 'heap.' But the nuraghi are neither hollow nor are they haphazard heaps of stone. The nuraghe interior often presents a complex plan of chambers, winding staircases, dead-end corridors, concealed rooms with trap doors, and a variety of niches and compartments. Standing up to three stories high with magnificently corbelled domes one on top of the other, some structures have as many as 18 subsidiary towers attached to the main keep. Large complexes were sometimes completely enclosed by enormous stone walls punctuated with still more towers." Ocer 3,000 years old, the nuraghi have withstood the depredations of weather and later humans by virtue of their excellent design and construction. As with many other such ancient structures, one is impressed with the size of the stones used. How were they moved? How were the stones -- usually hard basalt -- cut and dressed by artesans with no metal tools harder than copper or bronze? And what was the purpose of the nuraghi? A quick answer to the last question is that they ...
