... ago, Yale biologist H.S . Burr inserted electrodes into trees and found that the voltages between them varied with the phase of the moon. (Ref. 1) The influence of the moon upon trees is even more palpable: the diameters of tree stems also bloat and shrink with the position of the moon in the sky. There is a tide in the affairs of trees, it seems. If tides occur twice a day, so do the swellings and shrinkings of trees. These tidal patterns are evident even when the trees are kept in darkness and at constant pressure and humidity. Even more surprising, chunks of tree stems that are sealed to prevent water from flowing in or out will still expand and contract according to the 24-hour, 49-minute lunar cycle as long as the cambium, the most active growing region, survives. The dimensional changes are small -- only tenths of a millimeter, but even these seem too large, given the weakness of the moon's gravitational field here on earth. (Ref. 2 and 3) References 1.

Illumination of these regions somehow encourages our pineal glands to release melatonin. D. Jones has suggested a more direct way in which light can reach the pineal gland -- through our ears! The pineal gland, which is believed to be the relic of the third eye that our distant reptilian ancestors possessed, is now buried deeply in our brains. But, it is possible that light could reach it through the ears by diffusing through the soft, translucent tissues that lead into our skulls. A commercial opportunity arises here. Jones notes first that melatonin is a mood enhancer and stimulant. We all have read how depressed far-northern peoples become during their long winter nights; and we know first-hand how exuberant we are on bright spring days. Why not, asks Jones, manufacture "earlights" mounted on headbands? These would direct red light (which diffuses better through tissue) into the ears and thence to the pineal gland. People could thereby be made cheerful and enthusiastic whatever the season, weather, or time of day. We could dispense with all those mood-enhancing pills.

The geomagnetic field, the sun, the stars, prominent landmarks, and even odors help guide them across the continents and open seas. But birds are considered highly evolved animals so their sophisticated navigational techniques are not especially surprising. Monarch butterflies, however, are mere insects, with tiny brains (navigation-data processors) and not much in the way of the environment sensors and internal clocks required for long-distance migration. Yet, some of these colorful insects manage to flutter up to 4,000 kilometers from the eastern U.S . and Canada to their wintering grounds in Mexico. How do they do this? S.M . Perez et al have now shown that monarch butterflies are equipped with a sun compass; that is, they chart their courses by noting the sun's changing azimuth. This feat requires not only the measurement of solar azimuth but also reference to an internal clock. Humans cannot do this without artificial instruments. Furthermore, even on cloudy days, migrating monarchs fly in the proper direction (generally south-southwest). Apparently, they also have evolved a backup navigation system, perhaps a geomagnetic compass. (Perez, Sandra M., et al' "A Sun Compass in Monarch Butterflies," Nature, 387:29, 1997.) Comment ...

Parapsychology has ever been plagued by the appearances of seemingly robust psychic phenomena, such as Rhine's initial ESP experiments with Zener cards. These phenomena would excite parapsychologists for several years, even decades, and then fade away. Writing in a historical vein, Beloff put it this way: ". .. it soon transpired that a decline effect, for ESP no less than for PK, could persist across sessions and, ultimately, across an entire career. Nearly all the high-scorers eventually lost their ability. Even Pavel Stepanck, whose 10-year career as an ESP subject earned him a mention in the Guinness Book of Records , eventually ran out of steam. When, after a long break, he was retested recently by Dr Kappers in Amsterdam, he could produce only chance scores. I do not think it was loss of motivation or boredom in his case, as has sometimes been put forward as an explanation for the long-term decline effect, for it was Stepanek's great strength that he was constitutionally incapable of ever being bored! Nor can we take seriously Martin Gardner's attempt to explain how he might have relied throughout on trickery. If indeed he was a trickster, he should have steadily improved as he became more practiced. Whatever the explanation of these long-term declines, it must surely be something deep and pervasive."

The oceans, however, also move in ponderous cycles that beachcombers can never appreciate. Thanks to data from Geosat's precision altimeter, geophysicists can now discern some of these long-period moving patterns on the oceans' surfaces. "Energetic 90-day oscillations of sea levels have been intermittently observed at Wake Island in the western tropical Pacific during the past 2 decades. The oscillations tend to occur about 1.5 years after El NinoSouthern Oscillation events, to have amplitudes of 10-15 cm, and to persist for about 1 year.

The long passageway is aligned with the summer solstice sunset, also a feature of some ancient European structures, but hardly of any concern to a New England farmer. The Upton chamber seems to be associated with linear arrays of stones and stone cairns on nearby Pratt Hill. These alignments have obvious astronomical significance.

Where are those extraterrestrial emissaries anyway? Unfortunately, the extraterrestrial traffic seems to be going at warp speed in the wrong direction. Instead of interstellar spaceships converging on earth full of helpful aliens, everyone (or everything) seems to be fleeing our environs. The proof positive is in all those quasars with high redshifts.

Everyone expected that the impact of this comet on Jupiter would provide us with some very interesting phenomena, but most thought that the debris kicked up by the impacts would reveal something new about Jupiter -- not about comets, since everyone knows what they are! Instead, the long-held theory that comets are simply dirty iceballs is now questioned. Shoemaker-Levi-9 was originally classified as a comet because: (1 ) Its fragments all appeared to be surrounded by comas like all well-behaved comets; and (2 ) It was easily torn apart by Jupiter's strong gravitational field as it narrowly missed Jupiter in 1992. This is just what one would expect from a loosely compacted dirty iceball. But doubts about Shoemaker-Levi-9 's true nature have arisen because of two observations: (1 ) No water vapor has been detected in the plumes thrown up by the impacts of the fragments; and (2 ) The comet's Fragment M, which was supposed to have vaporized in 1993, as comets are wont to do, apparently did not and left a scar on Jupiter like the other fragments.

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.

So far, so good; but: "The fact that fully formed, optically visible internal radiohalos in diamonds are now presented casts a considerable shadow over current theories of diamond genesis."

In fact some of the half-lives are only minutes or days long. M.H .

The heat brought to the surface via this plume has created the volcanic chain as the surface plate has drifted over it during the past 73-or-so million years.

Perhaps our current fascination with computers has fostered this narrow view of heredity. Do our genes really contain all the information necessary for constructing human bodies?

Mammalian DNA contains fewer bases than amphibian DNA, even though mammals are considered more complex and "advanced." The implication is that "DNA-as-a -message" must be a flawed metaphor. Wings have been invented at least four times by divergent classes (pterosaurs, insects, birds, bats); and it is very unlikely that there is a common DNA sequence that specifies how to manufacture a wing.

The answer seems to be YES, as confirmed below: "Wingtip vortices have a core diameter of 20 to 40 feet and, as they trail behind each wingtip, remain approximately two wingspans apart. Why don't they enlarge in radius and dissipate? The rapid acceleration at the outer edge of the vortex produces low pressure in the core, and this pressure differential creates enough centrifugal force to hold the system tightly together for three to seven minutes. After that, friction takes its course, breaking these stubborn twisters apart into mere turbulence."

In the article that follows, R.A . Kerr reviews several recent studies of fossil bryozoans and snails. Some of these painstaking dissections of the fossil record were carried out by scientists initially committed to Darwinian gradualism.

Such abrupt speciation is tough enough to explain, but even more daunting are those species untouched by change over millions, even hundreds of millions of years. Indeed, the major characteristic of the fossil record and, therefore, earth life as a whole, has been stasis rather than speciation, despite all manner of asteroid impacts and climatic traumas.

That is, there seems to be no evolutionary advantage to looking alike. (Miller, Julie Ann; BioScience, inside front cover, March 1994. Miller's editorial remarks are based upon a later article by H.F . Nijhout, who also supplied the photographs. Nijhout's article explains how butterfly wing patterns may have evolved.) Comment. Cases of remarkable mimicry also occur among geographically separated species. For example, the North American Meadowlarks are dead ringers for the African Yellow-throated Longclaw. "Convergent evolution" names the phenomenon but doesn't tell how or why long chains of random mutations can come up with the same designs where there seems to be no "guidance" by the forces of natural selection. Perhaps genomes contain "subprograms" for those patterns and structures often used in biology. Of course, Sheldrake's idea of "morphic resonance" also applies here!

Science Frontiers ONLINE No. 102: Nov-Dec 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects From dust unto abyssal mud We know the Creator made at least one species from dust, but ocean-floor mud has turned out to have more biodiversity. Twenty years ago, biologists put the number of species at about 1 million. Then, they started shaking and gassing rain-forest canopies. The rain of new insect species that fell to the ground made them revise the estimate to 30 million. The latest, long-unappreciated reservoir of undescribed species is mud -- oceanic mud. In particular, we know that the mud in the Rockall Trench off the western coast of Scotland teems with untold species of diminutive nematodes. Of course, nematodes are not as pretty as birds and fish, but they are nevertheless bona fide species of life. Examination of the Rockall mud and that from other seabed sites has convinced the nematode counters that there may be as many as 100 million nematode species on our planet. When other classes of life are added, the figure rises to at least 130 million. (Pearce, Fred; "Rockall Mud Richer than Rainforest," New Scientist, p. 8, September 16, 1995.) Comments. Lifeless molecules can apparently unite to form an almost infinite array of life forms! The next reservoir of unexplored biodiversity may be the crevicular realm -- all those fluid-filled crevices and channels that extend miles down into the earth's crust. They are full of bacteria ...

November 16, 1994. Eastern North Atlantic. Aboard the m.v . City of Durban . Enroute from Le Havre to Capetown. As seen by three of the ship's officers: "At 2230 UTC the observers noted on both the 3-cm and 10-cm radars, as well as visually, a wave or band-like phenomenon shown as a succession of 'bands' approximately 4 n.mile long with a uniform separation of about 0.8 n.mile. "The bands appeared as if they were precipitation but on passing through one of them nothing was observed nor were there any other particles [i .e ., no wind-blown dust], seeing as the vessel was off the West African coast at the time. The bands themselves caused a rippling effect on the sea surface of roughly 150 m wide, giving an otherwise calm sea a black appearance beneath them on what was a well moonlit night. Although the phenomenon looked like rain bands, the observers could not give an otherwise definite solution for it."

... s atmosphere. Since this cataclysm is predicted to occur on Jupiter's far side, the pyrotechnics will be largely hidden from our telescopes. Yet, if any of Jupiter's four large Galilean satellites are swinging behind Jupiter during the comet's impact, but still visible to us by virtue of their distances from Jupiter, we might see one or more of these moons suddenly brighten due to light reflected from the incineration below. This very well might happen, and something similar has happened before. On July 26, 1983, just 6 minutes after it emerged from behind Jupiter, the Galilean satellite, Io, suddenly brightened by 50% -- a "flash" that lasted 118 seconds. Now, Io is notoriously fickle brightness-wise. Its post-eclipse brightening has long puzzled astronomers, but this short, intense flash was even more anomalous than usual. H.B . Hammel and R.M . Nelson suggest that this 1983 flash might have been the reflection of some catastrophic event occurring on the hidden half of Jupiter -- possibly the impact of some large object -- or, even more intriguing, Jovian lightning. (Hammel, H.B ., and Nelson, R.M .; "Bright Flash on Jupiter in 1983," Nature, 366:117, 1993.) Comment. Could this Jovian "lightning" actually have been an electrical spark? This thought dovetails nicely with the pair of "ghostly" infrared spots that race across Jupiter's surface in synchronism with Io's orbital motion. (See SF ...

... straight path, but often it would follow a really contorted path that made the "mist" look like a snake engaged in a rather violent path -- rather captivating to watch. "We suspected that the effect was some sort of remnant of the vapour trails that sometimes came off the tips of the wings and tried to confirm this by direct observation, but we could never keep track of such a trail for more than 5 seconds. Also, we were never totally convinced that the two effects were correlated. Anyway, wouldn't such a trail dissipate within a few seconds?" (Surendonk, Timothy; "Just Plane Weird," New Scientist, p. 58, March 5, 1994.) Comment. If these "mists" are merely trailing vortices, the long time delay between passage of the plane and the tube of mist is puzzling. From Science Frontiers #93, MAY-JUN 1994 . 1994-2000 William R.

... from the butterflies. Which is correct, or are they all correct? Back to the review. Waxing heretical, Williamson points out that an organism may have more than one phylogeny ! Larvae may have ancestries different from the adults. How heretical can one get? But in the ocean, spermatozoa often cannot find an egg of the correct species. They may then fertilize eggs of a distantly related species. In such "wide hybrids," the larvae may resemble one parent and the adults the other. There is much more. The gist of it all is that evolution has been much more than random mutation and natural selection. Hybridization and outright mergers (endosymbiosis) have played important roles. Even our own cells harbor mitochondria that have their own DNA. They are probably bacterial invaders that long ago settled down in the cells of our ancestors.

... A "local" magnetic storm began about 6 minutes after the explosion (If that is what it really was.) and lasted for more than 4 hours. These magnetic perturbations resembled those following nuclear atmospheric explosions. The Tunguska object left no smoky trail like many fireballs, but rather irridescent bands that looked like a rainbow. Following the "explosion," at least part of the object continued on in the same direction but veered upwards. [Meteors sometimes skip out of the atmosphere on trajectories like this.] Although the Tunguska event occurred on June 30, 1908, optical anomalies appeared all across northern Europe as early as June 23. These included mesospheric, silvery clouds, very bright nights, colorful twilight afterglows [something like those following the Krakatoa eruption], and remarkably intense and long-lasting solar halos. Some of these effects persisted until late July. Neither craters nor meteoric debris have been discovered so far, despite assiduous searches. The explosion created a shock wave that leveled 2150 km2 of taiga and a flash that singed about 200 km2.
