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.

"The dolmen is four feet across the top and has three placed stones holding it above the ledge in a level position approximately six feet from the cliff face. The Ogam on top of the capstone is intermixed with cupule-like depressions ranging in size from 7 "- 9 " long, 3"-3 " wide and 1 "- 1 " deep in the center. The cupule-like depressions are very striking because of their uniformity, smoothness, and peculiar shape. The Ogam on ... side of the capstone is abundant and occasionally connecting with lines on the top. The surface of the dolmen was obviously smoothed and prepared for the inscriptions. The actual age is unknown but the desert varnish on the Ogam, the depressions, and the smoothed surface is substantial." The Colorado inscribed dolmen in situ. The top is also inscribed.

... encountered -- or perhaps caused -- a most baffling display of marine phosphorescence lasting some 2.5 hours. The complete report is 6 pages long, with 8 diagrams, so only the highlights can be reported here. As is often the case, this display began with parallel phosphorescent bands (2 sets) rushing toward the ship at about 40 mph. They were 50-100 cm above the sea surface. The bands then changed into two rotating wheels; then a third wheel formed. All three rotated counterclockwise, with their hubs 300, 300, and 150 meters from the ship. The spokes stretched to the horizon. The display ceased for about 20 minutes and recommenced with four systems of onrushing parallel bands, which soon metamorphosed into four rotating wheels. Radar, visible light ... from an Aldis lamp), and engine revolution appeared to have no effect on the spectacle. Next, evenly distributed, circular, flashing patches of brilliant blue-white light appeared all around the ship out to a distance of about 150 meters. This system of patches flashed away simultaneously the wheel display. The patches varied from 15-60 cm in diameter, and flashed 114 times per minute. When an Aldis lamp played steadily on the patches, nothing happened. When the lamp was flashed, the whole array of flashing patches disappeared, only to reappear in about 2 minutes. Each patch seemed to consist of worm-like segments 2 cm long, 2 cm apart. The worms were all aligned perpendicular to a vector from the ship. In contrast to the bands and wheels, ...

Science Frontiers ONLINE No. 36: Nov-Dec 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Magnetic Jerk Problem We reported above that the earth's magnetic field "jerked" in 1969; that is, it suddenly accelerated its westward drift. The earth's core, which through dynamo action reputedly generates the magnetic field we detect at the surface, apparently does not keep pace with the outer crust. It is this sluggishness that produces the observed westward drift of the magnetic field of about 1 meter per hour. While most geophysicists acknowledge that something significant happened to the core in 1969, the geographical extent of the "jerk" is unclear. The acceleration of the field was clearcut in Europe but obscure or undetectable over ... of North America. If the jerk was geographically limited, the core perturbation probably was, too. The earth's core may, in fact, eddy and swirl like the planet's atmosphere. Going over past records, geophysicists think they have spotted another jerk in 1912; only that time the field decelerated.

Seen by hundreds, it generated many high quality reports. Fifteen of the written reports mentioned anomalous sounds -- hisses, hums, swishes, and crackling sounds heard simultaneously with the visual sighting. Such sounds are anomalous because the meteor is tens of kilometers high and real sound would take a minute or more to reach the ground. (The sound from a detonating meteor is often heard several minutes later.) Keay is convinced of the reality of the anomalous sounds and suggests that the highly turbulent ... in the meteor wake generates powerful electromagnetic radiation at audio frequencies. This intense radio energy reaches the earth at the same time the visible light does. It may be converted into sound as it interacts with the surface and the observer.

Such objects, he claims, could account for volcanic hot spots, gravitational anomalies, concentrations of mass on the Moon (mascons), the existence of the rings of Saturn, and even the observations that gave rise to the notion of a 'fifth force.'" J. Gribbin, whose article begins with the above paragraph, is quick to proclaim that this "theory of everything" is not just silly-season kite flying. Rather, it was proposed by A.P .

Expanding phosphorescent rings were observed emanating from a single point. These rings were equally spaced and expanded outwards for about 500 meters before disappearing. Rings with spoke systems also formed, rotating clockwise. The observers had the distinct impression that the rings were above the sea surface. We have reported on so many of these light wheels in the past 22 years that we have skimped on the details in favor of the comments made by P. Herring of the Southampton Oceanography Centre. "This is a fascinating account of the most spectacular (and rare) bioluminescent phenomenon known (I have a record of some 250 reports in the last 100 years) ...

It attracted attention only because its course was marked on the surface by stones projecting from the ground every 25-30 feet over a gently curving arc about 1,000 feet long. One of these surface stones seemed to be inscribed with strange symbols. Excavations, supported at first by the Smithsonian Institution, revealed a 3-ply sandstone wall-like structure seemingly cemented together by a reddish mortar. Splitting the sandstone sheets revealed diagonal rows of markings like those illustrated. At first, both wall and inscriptions were proclaimed to be artificial. More recent studies by geologists point to natural origins for the wall, the mortar, and even the inscriptions themselves. The latter may ...

Since the moon is virtually airless, there should be none of those gas molecules and suspended dust particles that cause the sunsets and sunrises that we admire so much here on earth. Still, there must be something suspended above the moon's surface to scatter light from the sun still located just below the horizon. The best guess is that lunar dust particles are ionized by solar radiation and are repelled upwards from the surface and hang there suspended by electrostatic forces.

However, mathematicians and computer modellers do have eyes. They have also had a lot of fun and some success in devising algorithms (mathematical methods) for the generation of seashell markings. In fact, our title above is also the title of a new book by H. Meinhardt, which suggests how a suite of simple biochemical processes can create those shells coveted by collectors. Meinhardt has devised equations that describe chemical factors that turn pigment-generating cells on and off. In its simplest form, a mathematically modelled seashell is a two-dimensional sheet that grows along only one edge. Cells on this edge ... of cells is permanently turned on, there is a dark stripe of pigment, and where the cells are dormant, there is an unpigmented space. The complementary pattern -- horizontal stripes, parallel to the growing edge -- results from a temporal rather than a spatial oscillation. All the secretory cells turn off and on in synchrony, so that light and dark bands are left behind on the surface of the shell as the growing edge moves on." All well and good, but some seashells have intricate patterns that require modellers to imagine traveling waves of excitation, oscillating chemical systems, signals that travel faster than chemical diffusion, and longrange synchrony employing a "global control element." These patterngenerating schemes are clever and rather successful on the theoretical level. Indeed, the seashell modellers are ...
