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.

Science Frontiers ONLINE No. 76: Jul-Aug 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Flying, parachuting, and falling frogs (Top) Shapes of flying and non-flying frogs. (Bottom) Aerodynamic diagram for a flying frog. Falling frogs have always been a Fortean favorite. These particular frogs plummet to earth in uncontrolled, unchecked free fall after (presumably) being lofted by whirlwinds. But there are frogs that are aerodynamically more sophisticated; these creatures glide and parachute through the dense tropical forests. S.B . Emerson and M.A .R Koehl have inquired into (even resorting to models in wind tunnels) the morphological and behavioral changes that have accompanied the repeated evolutions of these airworthy amphibians. "This paper reports an examination of the shift from aboreal to 'flying' frogs where we evaluate the the aerodynamic performance consequences of both a behavioral and morphological change. 'Flying' frogs have evolved independently several times among the 3,400 species of anurans. Although the particular nonflying sister species to each flying form remains unknown, in all cases flyers are distinguished from related, nonaerial, aboreal frogs by a similar suite of morphological characters: enlarged hands and feet, full webbing on the fingers and toes, and accessory skin flaps on the lateral margins of the arms and legs. 'Flying' frogs are not capable of powered flight, but do travel considerable horizontal distances during vertical descent. They are technically classified as gliders because they can descend at an angle less than 45 to the horizontal ...

... Science Frontiers ONLINE No. 57: May-Jun 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Unusually Large Snowflakes In a recent review of records of falls of very large snowflakes, W.S . Pike lists eleven instances where flakes more than 5 centimeters (2 inches) in diameter have been observed. Of these, we have already cataloged six in GWP2, in Tornados, Dark Days, Anomalous Precipita tion, including the prize of the lot: the 15-inch snowflakes that parachuted down on Fort Keough, Montana, on January 28, 1887. Five of Pike's cases that we did not catalog have diameters of "only" 5 or 6 centimeters. The sixth uncataloged observation would certainly have been worth including if we had known about it: March 24, 1888. Shirenewton, England. "Snowstorm with extraordinary flakes, some were 3 3/4 in. in diameter, yet only in. thick, falling like plates. The storm lasted only 2 minutes but in this short period the ground was covered 2 in. deep." The quotation is from British Rainfall, 1988, as requoted by Pike. In all cases, huge snowflakes are really aggregations of many thousands of individual flakes. Observers have thought that the big flakes attract individual flakes. (Pike, W.S .; "Unusually-Large Snowflakes," Journal of Meteorology, U.K ., 13:3 , 1988.) Comment. Could electrostatic forces be involved? Reference. The catalog Tornados, Dark ...

Biological Anomalies: Mammals I: A Catalog of Biological Anomalies Sorry, Out of print The first three biology catalogs deal with human anomalies. Here, we attend to the "other" mammals, and two volumes will be required This, the first, parallels Humans I in focusing on external attributes (1 ) physical appearance; (2 ) behavior; and (3 ) talents and faculties. Typical subjects covered: Mammal-marsupial parallelisms * Zebra stripe reversal * Marching teeth * Lunar effect on activity * Mammalian art and music * Rat and squirrel "kings" * Cetacean mass strandings * Mummified Antarctic seals * Navigation and homing * Soaring and parachuting * Mammalian engineering works * Deep-diving capabilities * Unusual vocalisations * Intelligence overshoot.
