The stars comprising a star cluster are usually assigned the same age, since it is thought that they were all created at the same time that the cluster was formed. Lurking in many star clusters, however, are brighter, bluer nonconformists called "blue straggler stars." These stars seem to have about twice the mass of the "normal" cluster members, and they appear to be only about one-fifth as old as their compatriots. The motions of the blue stragglers are consistent with those of bona fide cluster members, implying that they are not interlopers or foreground objects. Several ... have been suggested to explain the presence of blue stragglers. One thought is that they harbor asteroid-size black holes at their cores. So far, all of the profferred explanations have serious flaws. (Fogg, Martyn J.; "Blue Straggler Stars: A Cosmic Anomaly," The Explorer, 6:4 , Spring 1990.) Socket stars.

First, there is the phenomenon we have called "rocket lightning" in our books and newsletters. Scientists now call these upwardly directed discharges "sprites." (SF#84) The sprites are short-duration red flashes in the ionosphere, sometimes with bluish tendrils extending down into the thunderclouds. Second, there are the newly recognized "blue jets," a new class of upward discharges. This phenomenon is detailed in a paper by E.M . Wescott et al. Here is their abstract: "Initial observations of as newly documented type of optical emission above thunderstorms are reported. "Blue jets," or narrowly collimated beams of blue light that appear to propagate upwards from the tops of thunderstorms, were recorded on B/W and color video cameras for the first time during the Sprites94 aircraft campaign, June-July 1994. The jets appear to propagate upward at speeds of about 100 km/s and reach terminal altitudes of 40-50 km. Fifty-six examples were recorded during a 22-minute interval during a storm over Arkansas. We examine some possible mechanisms. but have no satisfactory theory of this phenomenon." (Wescott, E.M ., et al; "Preliminary Results from the Sprites94 Aircraft Campaign: 2.

Such mammals have bichromatic vision and discern colors rather well. Humans and the other primates are blessed with trichromatic vision, for their eyes have cones that register red light. Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it is easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on ...

Only the male humpbacks sing, and then only during the mating season. In contrast, the songs of blue whales are exceedingly dull. They consist of only five notes repeated in various combinations. Since both sexes sing most of the year, the songs of the blue whale probably have nothing to do with reproduction. Then, why do they sing? A clue to the purpose of the blue whales' songs is found in their precision timing. One note is sung every 128 seconds. Furthermore, these notes (sound pulses) carry for hundreds of kilometers. C. Clark, a Cornell scientist, believes these notes are really sonar pulses used for fixing a whale's location. Echoes returned from distant seamounts, continental shelves, and other undersea topography enable the whales to map their positions within the wide ocean basins as they wander far and wide. (Hecht, Jeff; "Rhythm of Blues Charts the Ocean Depths," New Scientist, p. 19, June 20, 1998.) Comment. Short -range sonar is widely used by bats, Oilbirds, Edible-nest Swifts, and, of course, dolphins. As far as we know, the blue whale is the only animal employing sonar for longrange mapping.

The recent confrontation between G.K . Kasparov, boasting two hemispheres of gray matter, and IBM's Deep Blue chess-playing computer, with its boards of silicon chips, suggests that the human brain may do things somewhat differently. Consider that in the 3 minutes allotted for each move, Deep Blue could evaluate 20 billion moves. This means that it could examine every possible move and countermove for twelve sequences ahead and, in addition, selected lines of attack for 30 sequences. Kasparov was obviously doing no such computation. Yet, he won two, drew two, and lost only one game. IBM's A.J . Hoane, Jr., remarked that chess geniuses like Kasparov "are doing some mysterious computation we can't figure out." Hoane's use of the words "mysterious computation" tells us that he is a reductionist. The implication is that everything mental can be reduced to manipulating those 1s and 0s. In reality, Kasparov's brain may have been innovating, working out new strategies, discerning Big Blue's weaknesses. These "higherlevel" functions are needed when the problem (chess) is too complex for a computer to evaluate all ...

Mars is now red because of its endless vistas of reddish soil and rocks, But most planetary scientists now insist that Mars was once blue, too. It was drained by gushing rivers and supported a vast ocean. The planet's many channels and layered deposits seem to prove Mars was, like Earth, once a water-rich planet. We like to think this way because we so much want to find life on our sister planet, and to us water is life! Not so fast! says N. Hoffman from La Trobe University in Victoria, Australia. According to his hypothesis, water has had little or no importance in shaping the Martian landscape. Instead, his 'White Mars' model contends that the gurgling, frothing and sometimes explosive venting of carbon dioxide gas from beneath the surface created the features. Outrageous as Hoffman's hypothesis is, it is supported by several significant observations that seem to deny a watery Mars. The Mars Global Surveyor has not detected any carbonate minerals that should have been created when water interacted chemically with the planet's CO2 atmosphere. Surface photos fail to show the fine networks of tributaries that should have fed the larger drainage features if water were the agent of erosion.

From these points there seemed to be emerging highly confused patterns of spiralling spokes moving in an anticlockwise direction on the port side and clockwise on the starboard side of the ship.

Kasparov. Incidental to the match itself was the fact that Big Blue sometimes made different moves when confronted with identical chessboards! With these denials of cyberdeterminism in mind, consider the following anecdote. About 40 years ago, D. Herschbach witnessed the first test of an early chess-playing program written by the renowned S. Ulam for the MANIAC I computer. "In this test, the MANIAC I computer played both sides of the board. After a rather bizarre game, Black made a move that checkmated White. Only then did Ulam realize that the program did not say what to do when mated; it just required that a move be made to escape check. While Ulam and his colleagues debated what might happen, the computer whirred on for about ten minutes. Finally it punched out White's move (on paper tape, then the mode). The uncanny solution: a spurious pawn appeared and began to march down the board to become a new queen." (Herschbach, Dudley; "Computer Milestones," Discover, 17:12, October 1996) Comment.

From California, A. Hastings writes: "I also had an experience with 'Sparks on the Beach' as in SF#104/4 . This was on the Pacific Ocean Beach at San Gregorio, south of San Francisco, several years ago. I was walking on fairly wet sand, just above the tide line. As I stepped, the sand around my feet lit up with small bright dots of phosphorescence. I would not have said that the color was blue, but it could have been like blue-white, like the star Rigel. I found that if I stepped hard or stamped my foot, the lights flashed brighter and the lit area went out farther from my foot. I could see the movement expanding out. After a stamp or two, they did not light up as much. I assumed that this was caused by some organism that lit up when it felt pressure, and 'wore out' after it had done this a few times -- a refractory period probably occurred." (Hastings, Arthur; personal communication, March 21, 1996) Comment. This is probably a pressureinduced biological phenomenon, but we have no idea what kind of organism produces the lights.

In this article M.A . Frizzell summarizes the most important attempts to come to grips with this phenomenon during the past 70 years. He concludes by describing recent experiments conducted by The Enigma Project and the Oak Ridge Isochronous Observation Network (ORION). Rather than repeat once again the older published observations, let us concentrate on the Enigma/ORION work. In May 1977, ORION placed a 500,000 candlepower arc light in Lenoir, 22 miles east of Brown Mountain. Simultaneously, a group of observers gathered on an overlook on Route 181, 3.5 miles west of Brown Mountain, a favorite spot for watching for the Brown Mountain lights. Brown Mountain itself was inter-posed between the arc light and obser-vers. When the arc light was switched on, the observers saw an orange-red orb hovering several degrees above the crest of Brown Mountain. Conclusion: the majority of the so-called Brown Mountain lights, particularly those seen above the crest, are refractions of artificial lights. The real Brown Mountain lights, the mysterious ones, are those that flit through the trees well below the crest. These lights are extremely rare.

These are the rays that penetrate to the greatest depths in the sea. This adaptation to blue light means that deepsea fish have evolved visual pigments different from those of surface fish and land animals. Visual pigments are complex chemical compounds, and one must suppose that many, many random mutations took place before deepsea fish were able to manufacture visual pigments different from their relatives living near the surface. (Or did deepsea fish come first?) But there is more to this story. Many dwellers in the black abysses generate their own light. They sport bioluminescent organs so they can be seen by others of their own species and, in addition, illuminate prey for easier capture. In another remarkable example of evolutionary convergence, these bioluminescent organs emit light spectrally matching the eye sensitivity of deepsea fish! So far, though, this story is not any more amazing that many others woven into evolution's fabric. But suppose that a deviant species of deepsea fish upset this cosy status quo by evolving visual pigment and bioluminescent organs operating in a part of the electromagnetic spectrum that other deepsea fish could not perceive.

It seems that the intense red light of the sun near the horizon can bleach the red-sensitive receptors in the retina so that an intent observer becomes temporarily color blind to red. When this happens, the observer sees the yellow part of the dispersed solar spectrum as being green (yellow minus red = green). The true green flash may never have appeared at all. (Seife, Charles; "Don't Let Your Eyes Deceive You," New Scientist, p. 5, June 5, 1998.) Comments. You are right! Blue lies beyond green in the spectrum. Much rarer than green flashes are blue flashes. Jules Verne even wrote a novel involving this famous phenomenon: Le Rayon Vert . Reversing the sequence, red flashes are sometimes observed as the bottom edge of the sun dips below a sharply-defined cloud deck. (From: Rare Halos...)

"At 2225 UTC when a light rain shower was falling, a rainbow was seen on the starboard side roughly 2-3 cables from the vessel. It was very clear for about six minutes and was accompanied by a secondary bow after about half that time. The secondary one did not make a complete bow but seemed joined to the primary bow at its highest point, in a convergence area of deep blue, as indicated in the diagram. "The colours were very clear, with blues and purples visible in both parts. Both bows began to fade at about the same time as the moon once again passed behind another cloud." (Crofts, A.; "Lunar Rainbow," Marine Observer, 69:67, 1999.) Comments. Because moonlight is much weaker than sunlight, lunar rainbows are rather rare. Even so, they are not anomalous. It is the offset bow that is difficult-to-explain. Rainbow phenomena should be symmetrical around the line containing the light source (moon, here) and the bow itself. In GEB3 in Rare Halos, we note that no reasonable explanation exists for rainbows offset to one side. However, extra bows offset directly above the main bow can be explained as due to reflection of moonlight or sunlight off ...

Want to bet that this assumption is correct? And don't forget that genes jump around. The genome is really a moving target. Genes also work in concert. It is not one gene coding for one protein, which then has a singular role in creating an operational human being. For example, some 5,692 genes are active in breast-cancer cells. Genes may also have multiple roles. Our present blueprint of the human genome does not display all the mobility and complex interrelationships of the genes. We do know that genes are the blue-prints for the manufacture of proteins. Of these, there may be over 1,000,000 different -- more than ten times the number of genes! These multitudinous proteins are continually being created and transported to where they perform their assigned tasks and are eventually deconstructed. It is this population of proteins (collectively the "proteome") that develops organisms and gives them life. We do not begin to have a blue-print for the proteome, which really tells us how life works. Then, there are epigenetic influences. "Epigenetic?"

Alcock contends that the admitted enigmas of quantum mechanics are being unfairly twisted by the parapsychologists.

You and I cannot hear caterpillar songs, but some ants can, and they are attracted to these insect sirens. The singing caterpillars belong to the Lycaenidae, which include such butterflies as the hairstreaks and blues. It is not only the singing or vibrating of this group of caterpillars that makes them remarkable, it is the complexity of their symbiotic relationships with several species of ants and a plant. Since both the ants and the caterpillars favor the Croton plant, they could well meet by chance, but the caterpillars' singing serves to accelerate contact. Once met on the Croton plant, a fascinating triangle is completed. Player 1.

"Following sunsets of exceptional beauty and twilight effects remarkable even in England, the northern sky at midnight became light blue, as if the dawn were breaking, and the clouds were touched with pink, in so marked a fashion that police headquarters was rung up by several people, who believed a big fire was raging in the north of London."

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.

There was a band measuring 35 long in azimuth, with deepblue almost black vertical bands lying between the altitudes of 15 and 25 . The colour changed to brilliant blue at 0335, lasting for about 15 minutes before cloud began to obscure it." What were the "almost black" vertical bands embedded in the main band? Aurora expert R. Livesey replied as follows. "There is a phenomenon called the 'black aurora' which consists of small regions of very low luminosity embedded in brighter auroral light; the 'black' rays reported from the Appleby could have been a phenomenon of this type." (Wilson, J.L .; "Aurora Borealis," Marine Observer, 69:112, 1999.) Black auroras may actually be more than just the contrast effect suggested by Livesey. Low-light TV systems detect clockwise vorticity in the black bands, and the bands seem to be associated with upward electron beams. In other words, black auroras are apparently a distinct phenomeon in their own right and not just nonluminous parts of the visible aurora.

America was obviously the source of this scourge, but how did it ever get to Europe? Of course, every child knows that Columbus sailed the ocean blue in 1492. It seemed pretty certain that Columbus's men and the American aborigines had been very, very friendly. Actually, about a dozen pre-1500 skeletons displaying hints of the disease had been found in England and Ireland, but they were not convincing enough to dethrone the Columbus theory. Recently, however, several additional syphilitic skeletons were dug up at a medieval friary in northeastern Britain. The earliest of these bones date back to about 1300. In fact, the new evidence suggests that there was a geographically limited mini-epidemic of syphilis in Britain about this time. Columbus was now off the hook, but who should be hung on it instead?

These two young blue stars are very close -- only one fifth the distance from earth to our sun. They orbit about a common center of gravity every 10.55 days. So far, no problem! The puzzle is that, as the two stars swing around one another, the axis of their orbit rotates or precesses too slowly. General relativity predicts a precession of 4.27 /century, but for DI Herculis the rate is only 1.05 /century. This does not sound like a figure large enough to get excited about, but it deeply troubles astronomers. D. Popper, an astronomer at UCLA, says: "The observations are pretty clear. I don't think there's any question there's a discrepancy and, frankly, it is an important one and it's unresolved." Accentuating the challenge to general relativity is the discovery that a second eclipsing binary, AC Camelopardalis, also violates general relativity in the same way. It seems that wherever gravitational fields are extremely strong and space-time, therefore, highly distorted, general relativity fails. Ironically, it was a very similar sort of astronomical observation that helped make general relativity a pillar of the scientific edifice early in the 20th. century.

Despite the political incorrectness of Caucasians in "America B.C ." some scientists seem ready to accept the testimony of the bones, even while rejecting later epigraphic evidence. D. Stanford, at the Smithsonian's National Museum of Natural History, muses: "I think we're going to see the whole complexion of North American prehistory change real fast."

... off Christmas Island in the Indian Ocean. A report was heard on the Christmas Island Radio that an object had been spotted high in the sky to the west of the island. The officers of the Baron Pentland picked up the object with binoculars and sextant. "First thoughts were that this was the satellite Cosmos 1402, but this was dismissed as it was a day too early and it was not moving fast enough. In fact it appeared stationary to the naked eye. Another school of thought was that this was a weather balloon. As can be seen from the simple sketch, it was unlike any weather balloon previously seen by the observers. It was of a squat cylinder shape, wider than it was tall. The circle at the bottom appeared to be dimly lit with a pale blue colour. The 'torso' was almost invisible, even with binoculars, giving the impression that there were two distinct and separate lights. The top 'light' appeared to be a dome atop the main body and it was extremely bright. By wedging the binoculars in the bridge doorway, it was possible to gain a very steady view as the vessel's main propulsion system was shut down and the seas were light. Thus a clearer picture was obtained and in this way the object was identified as being cylindrical. The bottom circle also appeared to be 'webbed' with dark radial lines." At 0643 GMT, the object had disappeared in the west. (Strachan, C.; "Unidentified Flying Object," Marine Observer, 54:27, 1984.) ...

". .. the atmosphere was suddenly invaded, in Europe, by a sort of dry fog of peculiar character. It did not moisten objects, did not affect the hygrometer, and persisted when the wind rose, and rain fell. The sun looked pale through it. This fog lasted a month.

". .. a similar fog was observed throughout Western Europe; it lasted twelve days. It deprived the sun of so much brightness, that one could look at this star at any hour; it gave the disc a glossy blue tint. Twilight assumed an extraordinary brightness, so that the day was greatly prolonged, and one could even read at midnight."

... larger, and seemed to be partly filled with a bright cloud, which shimmered like a fluorescent light. This brilliant cloud was in the middle of the funnel, not touching the sides, as I recall having seen the walls extending on up outside the cloud. "Up there, too, where I could observe both the front and back of the funnel, the terrific whirling could be plainly seen. As the upper portion of the huge pipe swayed over, another phenomenon took place. It looked as if the whole column were composed of rings or layers, and when a higher ring moved on toward the southeast, the ring immediately below slipped over to get back under it. This rippling motion continued on down toward the lower tip." Hall also reported a peculiar bluish light and blue streamers that appeared to consist of vapor.

By now, we were down to a very slow speed, and under closer observation we noticed that the area was littered with millions of hailstones and those toads hopping all over. "The storm stopped as fast as it started, and the toads disappeared just as fast. I'll never forget how slippery the road was as we drove over those toads, and the popping of their bodies under the tires of my automobile."
