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. 113: Sep-Oct 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Green Thunderstorms Anecdotes abound that exceptionally severe thunderstorms may appear to emit an eerie, sickeningly yellow-green light. Skeptics scoff at this notion. The excited observers were deluded, or they made it all up. This is, of course, the same knee-jerk response greeting UFO reports and accounts of many other anomalies. Thunderstorms, however, do have an objective existence. And it turns out that a few storm-watching meteorologists have also seen greenish thunderstorms. Such professional testimony is usually dismissed as due to the reflection of greenish ground vegetation by the storm clouds or, perhaps, the effects of sheets of hail preceding the storms. In 1995, F.W . Gallagher et al decided to settle the matter. They chased likely looking thunderstorms armed with a spectrophotometer. Many storms later, they proved, first of all, that some thunderstorms are definitely green. In fact, some gradually change from blue to green in the space of half an hour. Their ground observations, plus more spectrophotometer data taken from aircraft, refute the theory that the green color is from reflected vegetation. Hail may contribute to the green color but is not required. In sum, green thunderstorms really do exist, but no one yet knows where all the green comes from.

Blue flashes are much rarer but still well-recognized phenomena. An example of the latter was observed in 1995 on the Indian Ocean. August 11, 1995, Bay of Bengal. Aboard the m.v . Repulse Bay enroute Jeddah to Port Klang. "Prior to sunset the vessel was proceeding due east across the Bay of Bengal and it was quite apparent that the sun was still very bright and had not taken on its usual darkorange or red appearance; even with half its diameter above the horizon, the sun was much too bright to view directly. As the last segment of the sun dipped below the horizon, a blue 'horn' formed at each end of it, as shown in sketch (a ), and these then closed up to form a bright-blue arc, as shown in sketch (b ). " (Leslie, A.J .; "Blue Flash," Marine Observer, 66:115, 1996) Comment. The blue flash is a shorter-wavelength version of the green flash. The basic phenomenon is explained in terms of dispersion of the sun's spectrum by the atmosphere near the horizon. Even so, many enigmas remain about these low-sun phenomena. There have been observed: multiple flashes, flashes preceding sunset, complex flash ...

Southern Bavaria, Germany. R. Urbanek, a teacher from Wasserburg, recalls her encounter with ball lightning. "I was with a friend in the area of Traunstein. My friend drove a minibus...150-200 meters...ahead of my car. Golf and several other cars were following behind me. It (had been) raining with heavy lightning and thunder. I did not drive at normal speed in such a weather...Then came a straight stretch of road with a bicycle path to the right, and an open wide field...Suddenly I saw a bright green, phosphorescent...ball about the size of a medical training ball, that dropped to the ground behind the minibus...It fell to the road and rolled towards me . I knew immediately it was ball lightning, and from school physics I knew a car acts as a Faraday cage. So I kept my feet to the floor mat and grabbed the wheel with both arms. 3 to 5 seconds passed until the ball reached my car. It came in a straight line, with a slight deviation to the right (as seen from my position). When the ball caught my car at the right front side, it gave the vehicle a strong shock or jerk, as if I had driven against an obstacle . All that was on the right side of me ...

North Atlantic Ocean. "At exactly 2155 GMT, a white seasmoke type mist was observed glowing white between 2 and 5 metres above the sea surface. Further observation revealed that we were entering a large area of circulating bioluminescence of defined spiral form which appeared to be a pale emerald green in colour. Although the direction of rotation and the centre hub of the wheel could not be determined, the bands appeared to be of great dimension. While still proceeding through the bioluminescence and observing astern, it was noted that the formation of the bands became disrupted and seemed to diffuse a ragged appearance at the perimeter of the wheel to the port side of the vessel. Judging by the distance of the vessels close by -- which were being tracked by radar -- the extent of the rotating bands to the west could not be determined but they were estimated to be between and n. mile. The duration of the phenomenon was 4 minutes from entering to leaving the bioluminescence." (Lehepuu, K.; "Bioluminescence," Marine Observer, 52:76, 1982.) Comment. Bright marine bioluminescence is not uncommon in the Atlantic, particularly in warm waters, but it is very unusual to find geometrically organized displays. The light wheels seen in the Persian Gulf and South China Sea are more frequent and more highly structured. No one has ever come up with a ...

Science Frontiers ONLINE No. 120: Nov-Dec 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Where Did They Come From?It appears more and more likely that South America was colonized earlier and separately from North America. Reason #1 is that the oldest recognized sites in North America are only 11,200 years old, while the Monte Verde site in southern Chile is now generally admitted to be 12,500 years old. Reason #2 is the distance gap of about 5,000 miles between the two sites. So far, there is no evidence of cultural continuity. The time gap is likely to enlarge in a huge quantum jump because of excavations at an intriguing green knoll at Monte Verde. Some 6 feet below its surface is a sedimentary layer containing charcoal in clay-lined pits and humanfractured pebbles. This sedimentary layer is carbon-dated at 33,000 years ago -- some 20,000 years before the ancestors of North America's Clovis people are said to have trekked across the Bering land bridge. (Wilford, John Noble; "Chilean Field Yields New Clues to Peopling of Americas," New York Times, August 25, 1998. Cr. M. Colpitts) New Clues. Just to the north of Monte Verde, on the coast of southern Peru, traces of a hitherto unknown, 11,000-year-old maritime culture have emerged. For short, the new site is called QJ-280 (for Quebrada Jaguay 280). QJ-280 is now ...

Sea turtles are airbreathers that make long, deep dives. To descend deep for long periods, they have evolved a diving adaptation radically different from that employed by the dolphins, whales, and seals; namely, rectal gills. They breathe air at the front end and water at the rear. Water is pulled in through the rectum and directed to sacs lined with blood vessels. These function like fish gills by extracting oxygen from the seawater. The oxygen-depleted water is them expelled and another "breath" is taken. (Green, John; ISC Newsletter, 11:10, no. 3, 1991.

Science Frontiers ONLINE No. 97: Jan-Feb 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A Line In The Sea What would create a deep green line 10 kilometers wide and stretching for hundreds of kilometers across the azure Pacific? Sailors have remarked on this line as their ships clove it. It is so large that astronauts on the Space Shuttle Atlantis have photographed it from hundreds of kilometers up. Sample analysis proves the green line to be a particularly dense concentration of phytoplankton, which thrives along the boundary where the North Equatorial Counter-current meets the colder South Equatorial Current. The microorganisms feed in the richer, cooler, sinking waters of the latter and then rise to the surface to create the green line. (Yoder, James A., et al; "A Line in the Sea," Nature, 371:689, 1994. Also: Adler, T.; "Microorganisms Create a Line in the Ocean," Science News, 146: 263, 1994.) Comment. Even more unusual lines may be created where oceanic currents meet. For example, in 1932 an immense congregation of sea snakes 10 feet wide and 60 miles long was observed in the Malacca Strait. (SF#4 ) From Science Frontiers #97, JAN-FEB 1995 . 1995-2000 William R.

Strait of Hormuz. Aboard the m.v . BP Argosy enroute to Jubail. "At around 1710 UTC large but faint whitish patches of bioluminescence were observed on the port side of the vessel; they were fast-moving with random directions of movement. Over the next five minutes the intensity of the bioluminescence increased to patches of brilliant flourescent green, while the random pattern of movement suddenly changed to fastmoving parallel bands heading toward the vessel. The pattern then changed again to form numerous rotating spirals: some were confirmed to be rotating anticlockwise but it was difficult to assess owing to the large number of overlapping patterns." "At this point the vessel was surrounded by the phenomenon to a distance of approximately 1 n. mile radius. Yet again the patterns changed, this time to parallel concentric circles moving outwards from numerous centres. The display started to decrease at 1725, returning to milky-white patches before eventually disappearing at 1730." (Watson, M.M .; "Bioluminescence," Marine Observer, 65:59, 1995.)

"He suddenly realised everyone was staring upwards at objects descending from the sky. "He said: "I looked up and these massive lumps -- some as big as bales -- were gracefully floating down. It was beautiful. .. .. . "Mr. Davey estimated as much as ten tons of straw had fallen. The whole of the surrounding area was covered in it." (Anonymous; "Glory! Glory!

... looking shrub growing on rocky terrain in Western Australia, where it reaches a height of 2 meters. The fruits of this plant are enjoyed by the white-tailed black cockatoo -- if it can identify them ! Hakea trifurcata , you see, grows fruit that looks like its leaves, and this is very frustrating to the white-tailed black cockatoo: "This shrub according to plant ecologist Byron Lamont of Curtin University of Technology in Perth, exhibits the first known case of self-mimicry in a plant: to avoid losing valuable seeds to predators, it disguises some of its leaves as fruits. Young plants produce only the long, needle-shaped leaves. But mature five-year-old shrubs also grow broad leaves that cluster around the slightly smaller, almost identical-looking green seed-filled fruits." When offered branches stripped of real leaves and bearing just fruits, the cockatoos quickly demolished them. Normal branches bearing both leaves and fruit were attacked at first -- especially the larger leaves. But when the cockatoos found themselves duped a large proportion of the time, they gave up in obvious frustration. (Anonymous; "Fruit Dupes," Discover, 15:16, August 1994.) Comment. An even more amazing case of plant mimicry occurs among Passiflora species, which craft precise copies of the eggs of a butterfly, whose larvae decimate these plants. The butterflies see the fake eggs and go look for places to lay their eggs where there is less competition. (See SF#16) From Science Frontiers #97, JAN-FEB ...

At about the same time Sky and Telescope printed the frozen pizza item, Time had a cover story on the origin of life. It was in response to this story that M.D . Greene wrote the following letter to Time : "Forget bubbles, comets or ocean vents. Scientists should be looking at pizza for the answer. I can remember when my college roommates and I routinely created life every week in our refrigerator. My theory is that around 4.5 billion years ago, the earth was bombarded by intergalactic pizzas. These then provided the ideal breeding ground in which early organisms could thrive and later evolve." (Greene, Mark D.; "How Life Began," Time, 142:8 , November 1, 1993.) Comment. Charles Fort would certainly have chuckled over the near-simultaneous mentions of intergalactic pizzas in two diverse publications. A second report underscores the mystery presented by the unexpected diversity of life in the deep-sea ooze. J.D . Gage and R.M . May ponder in Nature : "Why there should be such exuberant biological diversity in an environment apparently lacking in the habitat complexity of, say, tropical rain forest -- whose species richness it might rival -- remains an enigma ...

Malacca Strait. Uniform crescents of luminescence appeared suddenly. Horizontal to the sea surface, they moved around the ship in circles, starting just forward of the bow. The crescents were about 100 meters long, 0.5 meter wide, light green in color, and passed the observers at the rate of three per second. The display was centered on the ship and moved with it. Some thought the crescents were above the sea surface, others placed them on the surface itself. (Lardler, D.A .; "Bioluminescence," Marine Observer, 51:116, 1981.) Comment.

... the earth's atmosphere. Of course, such treatment of strange phenomena is not new, nor is it undesirable, for we do want to confront reality whatever it might be. However, the two "wipes" in Sky & Telescope do seem a bit arrogant, especially when famous scientists do not hesitate to employ ghostly ephemera to support theories favored by the establishment. Strange eclipses. Down the years, many fantastic solar coronas have been sketched during the few minutes of totality. Long coronal petals and errant streamers, often asymmetrically arrayed, are common in the Nineteenth Century astronony journals. Scientists have no problems with these. It is the highly geometrical coronas that are hard-to-account-for. The reported colored coronas, too, seem unlikely. Red, blue, and green hues are definitely frowned upon. Coronas should be brilliant white, perhaps yellowish. S.J . O'Meara, a contributing editor of S&T , thinks many of the older and wilder drawings of coronas can be pinned on observer enthusiasm and active imagination. Modern photographs of coronas provide a much more conservative picture of the eclipsed sun. As for all those old observations of colored coronas, aerosols in the atmosphere, perhaps of volcanic origin, could have added the delicate tints reported. No unusual phenomena were involved. Problem solved! (O 'Meara, Stephen James; "Strange Eclipses," Sky & Telescope , 98:116, August 1999.) E.L . Trouvelot's portrait of the total solar eclipse of July 29, 1878 as seen from ...

Green St. Elmo's fire was glowing on the aerials. "At about 2310 it was also noted that the lever extending about 18 cm over the ship's starboard bridge wing to position a deck light was also radiating light. This light was a pale violet glow extending in 'spokes' of 10 cm in length from the round end of the lever which was about 3 cm in diameter. "There were six individual and uniform spokes shot through with brighter purple and white bolts resembling lightning. Over the noise of the wind a sharp crackling and hissing sound could be heard coming from the phenomenon. "The seaman was called to have a look at the light, he attempted to touch it but the light receded as his finger approached within 3 cm of it. The effect died away at about 2340 as soon as rain started to fall." (Smedley, R.; "Corposants," Marine Observer, 69:55, 1999.) Comments. The corposant's six-fold symmetry is like that of snowflakes.

Science Frontiers ONLINE No. 126: Nov-Dec 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Flotsam On The Great Sand Sea One of the strangest mysteries nestled among the giant dunes of the Egyptian Sahara was not recognized by modern scientists until 1932. In December of that year, P. Clayton, a surveyor for the Egyptian Geological Survey, was driving among the dunes near the Saad Plateau when he heard his tires crunch on something that wasn't sand. It turned out to be large pieces of marvelously clear yellow-green glass -- not just any glass but ultra-pure glass, 98% silica. As often the case, Clayton was not the first to come across the now-famous Libyan Desert Glass or LDG. Prehistoric humans had made knives and other sharp-edged tools from it; the ancient Egyptians had carved a scarab from LDG and deposited it in Tutankhamen's tomb. But Clayton and the ancients did not recognize the scientific implications of their discovery. LDG is the purest natural silica glass ever found. Over a thousand tons of it are strewn across hundreds of kilometers of bleak desert. Some of the chunks weigh 26 kilograms, but most LDG exists in smaller, angular pieces looking like shards left when a giant green bottle was smashed by colossal forces. Pure as it is, LDG does contain tiny bubbles, white wisps, and inky black swirls. The whitish inclusions consist of refractory minerals, such as cristobalite. The ink-like swirls, though, are rich in iridium ...

... Science Frontiers ONLINE No. 123: May-Jun 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Sophisticated Chemistry In Ancient Egypt The ancient Egyptians applied cosmetics copiously to themselves. Upper-class women (perhaps men, too) favored green, white, and black makeup. These cosmetic powders, dating from 2,000 B.C ., have been exceptionally well preserved in their original vials made of alabaster, ceramic, and wood. A team of French chemists led by P. Walter was not surprised when their analyses of these powders found crushed galena and cerussite (two ores of lead). However, they nearly dropped their test tubes when they also found chemical compounds that are extremely rare in nature; specifically, laurionite (PbOHCl) and phosgenite (Pb2 Cl2 CO3 ). In fact, these compounds are so rare naturally that the Egyptian powders must be artificial. P. Walter et al wrote: "Taken together, these results indicate that laurionite and phosgenite must have been synthesized in Ancient Egypt using wet chemistry. The Egyptians manufactured artificial leadbased compounds, and added them to the cosmetic product. The underlying chemical reactions are simple, but the whole process, including many repetitive operations, must have been quite difficult to achieve." It had been recognized earlier that the Egyptian chemists had used fire-based technology 500 years earlier (2 ,500 B.C .) to manufacture blue pigment. Wet chemistry represented another forward technological step. (Walter, P., et al; "Making Make- ...

... Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Forest Rings No! These rings have nothing to do with crop circles, nor with fairy rings either. Forest rings are best appreciated from a light plane. Hunters and hikers in Canada's boreal forests walk right across the rings without noticing them. But from the air, they are striking apparitions. Most are less than 300 meters in diameter, but the largest is 2 kilometers across. Basically, they are annuli of sparse growth amid dense stands of trees both inside and outside the rings. The barren rings -- some 2,000 have been found -- appear light-colored against the dark green of the healthy forest growth. Why don't trees grow well within the rings, and why the neat circles? At first expanding rings of fungus infection were suspected, something perhaps like the fungus that creates those fairy rings on lawns. But no fungus has been found on the tree roots. One curious fact was discovered about the soil where tree growth is sparse. The soil constituting the rings is poorly drained and is depressed 1-2 meters below the surrounding healthy forest. These circular depressions support mainly peat and tamaracks. But what causes these ring-shaped depressions? One theory holds that the rings are the suface expressions of diamond-bearing kimberlite pipes, like those in South Africa. A few prospectors are already staking diamond-mine claims! Another theory supposes that the rings are created by huge ...

Science Frontiers ONLINE No. 139: Jan-Feb 2002 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Mysterious First Green Egg In SF#138, we addressed the subject of birds' eggs as signals. Another similar and even more curious case occurs on the Antipodes Islands 500 miles southeast of New Zealand. There, five species of erect-crested penguins breed. These birds normally lay two eggs but raise only one chick. The first egg is distinctly greenish and much smaller than the second white egg. The little greenish egg is totally neglected and often ejected from the nest. No one knows why. (Davis, Lloyd Spencer; "A Superlative Penguin," Natural History, 110:46, November 2001.) First and second eggs of an Erect-Crested Penguin, respectively. (Left) Small and greenish (Right) Large and white. Comment. We suppose the first little egg could be a trial run of the female's reproductive machinery. Its small size and subsequent neglect seem to indicate that it is not a "back-up" egg in case the second egg is defective or eaten by a predator. Or maybe the little egg is a sop to predators with a hope that they will be satisfied with it. It would be interesting to know if the first eggs are ever hatched and what sort of chicks emerge.
