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. 29: Sep-Oct 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Porpoise Stun Gun Just about everyone knows that some whales and porpoises have oil/wax-filled sound lenses in their foreheads. These biological lenses focus clicks and other sounds sonar-fashion ahead of the swimming animal, which then listens for echoes from prey and other targets. But what if these bursts of sound could be made very powerful -- could they be employed to stun and disorient prey? Bits of evidence are accumulating to support the theory that some whales and porpoises actually have acoustic stun guns in their foreheads. First, there are visual observations of fish being hunted by whales and porpoises suddenly giving up flight, becoming passive, and almost asking to be snapped up by their pursuers. Second, the stomachs of whales often contain much faster and more mobile prey -- often without any teeth marks. Finally, bottlenose dolphins are known to have the capability of producing bursts of sound five orders of magnitude more intense than their usual navigating clicks. This is more than enough to kill small fish. (Norris, Kenneth S., and Mohl, Bertel; "Can Odontocetes Debilitate Prey with Sound?" American Naturalist, 122:85, 1983.) Comment. Here is another instance of the "problem of perfection." An existing organ of great complexity seems utterly useless of only fractionally developed. One would think that the complicated sound lenses, the muscular sound-generating tissues, and their containing structures would ...

... Science Frontiers ONLINE No. 13: Winter 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Human Compass In recent years, scientists have found magnetic material (magnetite) in birds, snails, porpoises, bacteria, and other animals. The utility of these biologically manufactured compasses is obvious. Humans, too, seem to have a magnetic sense, although no one has yet dissected the human head to search for magnetite crystals. Rather, the proof of a magnetic sense comes from direction-finding experiments by Robin R. Baker, in England. In a series of tests involving many subjects, blindfolded humans have been taken far afield and then asked, while still blindfolded, to point "home" and north. The results were surprising. Sense of direction was not lost despite long journeys. Furthermore, tests after removal of the blindfolds showed a marked deterioration of the directionfinding ability. The attachment of magnets and simulated magnets to the subjects proved that the magnets upset di-rection-finding capabilities. The controls with brass "magnets" retained their magnetic sense. (Baker, Robin R.; "A Sense of Magnetism," New Scientist, 87:844, 1980.) Reference. To read more about the human navigation sense, see BHT18 in our Catalog: Biological Anomalies: Humans I.

... Science Frontiers ONLINE No. 43: Jan-Feb 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Piscatorial Data Processing Mammals such as bats and porpoises have their acoustical navigational gear, while many fish have opted for electrical methods of scanning their surroundings. The short-range "radars" of these fish are marvelously sophisticated, considering the low limb fish occupy on the Tree of Life. In fact, the following introductory paragraph from an article in Nature sounds almost as if it came from a textbook on electronic signal processing. "Behavioural experiments have demonstrated that certain species of fish can perform remarkable analyses of the temporal structure of electrical signals. These animals produce an electrical signal within a species-specific frequency range via an electric organ, and they detect these signals by electroreceptors located throughout the body surface. In the context of one electrosensory behaviour, the jamming avoidance response (JAR), the fish Eigenmannia determines whether a neighbour's electric organ discharge (EOD), which is jamming its own signal, is higher or lower in frequency than its own. The fish then decreases or increases its frequency, respectively. To determine the sign of the frequency difference, the fish must detect the modulations in the amplitude and in the differential timing, or temporal disparity, of signals received by different regions of its body surface. The fish is able to shift its discharge frequency in the appropriate direction in at least 90% of all trials for temporal disparities as small as 400 ns." (Rose, Gary, and Heiligenberg, ...

Science Frontiers ONLINE No. 70: Jul-Aug 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Bird Brain Alex can name 80 things, tell colors, and even seems to be able to handle a few abstract ideas. Alex is not a chimp or porpoise. Alex is an African grey parrot, who has been living in an avian Sesame Street for 13 years. Parrots are wonderful mimics and pretty bright as birds go. Nevertheless, skeptics scoff at Alex's accomplishments as only the product of long, intense training. Alex can't be too dumb. Once when he couldn't lift a cup covering a tasty nut, he turned to the nearest human assistant and demanded, "Go pick up cup." Who's training whom? (Stipp, David; "Einstein Bird Has Scientists Atwitter over Mental Feats," Wall Street Journal, May 9, 1990. Cr. J. Covey.) From Science Frontiers #70, JUL-AUG 1990 . 1990-2000 William R. Corliss ...

... pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Does ri = mermaid?The astounding item that follows is taken from the new journal Cryptozoology, which is the official journal of the International Society of Cryptozoology. The Society was founded by a group of scientists interested in unrecognized species of animals. "An aquatic creature roughly resembling the traditional 'mermaid,' and sometimes identified with it, is reportedly known through a variety of encounters with natives of Central New Ireland. The ri, as they are called, are frequently sighted by fishermen, occasionally netted or found dead on beaches, and sometimes eaten. Males, females and juveniles are reported, subsisting on fish in the shallow seas around the Bismarck and Solomon archipelagos. It is unlikely that the animals are dugongs or porpoises, both of which are known to, and readily identified by, the natives." New Ireland is northeast of Papua-New Guinea. The article proper goes on to describe the ri as an air-breathing mammal with human-like head, arms, genitalia, and upper trunk. The lower trunk is legless and terminates in a pair of lateral fins. (Wagner, Roy; "The Ri -- Unidentified Aquatic Animals of New Ireland," Cryptozoology, 1:33, 1982.) Reference. Unrecognized mammals are cataloged in Chapter BMU in Biological Anomalies: Mammals II.
