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!

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.

Vasilyev has prepared a lengthy review of the 1908 Tunguska "event," which is usually ascribed to a wayward comet or meteorite. Vasilyev's data is based upon 167 reports, mostly in Russian. They show once again that this was no ordinary impact event, as illustrated by the following observations: 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. ...

Its composition and fused crust suggest an extraterrestrial -- origin probably Mars. Space scientists think ALH 84001 was blasted off the Martian surface by an impacting body 14-18 million years ago, based upon its exposure to cosmic rays while circling the sun, edging ever closer to earth. The composition of ALH 84001 tells us curious facts about its place of origin. First, it contains carbonate minerals deposited by water. Second, the carbonate grains are banded, implying the parent rock formation was washed by water more than once. Third, and most interesting, chemists have found traces of molecules called PAHs, based on interconnected benzene rings. Three sources have been proposed for these PAHs: Terrestrial contamination Prebiotic activity on the planet of origin PAH-bearing comets and/or asteroids impacting the parent planet. Terrestrial contamination has always been a problem in analyzing meteorites, but great care has been taken in recent years, especially with the Antarctic lode of meteorites. In view of these precautions, it seems rather likely that somewhere "out there" life is brewing. (Anonymous; "A Chip Off the Old Mars," Sky and Telescope , 90:12, July 1995.)

An astronaut standing on the moon watching the spot where the sun is about to rise would see first of all two well-recognized phenomena: the solar corona (even though the solar disc is still well below the horizon) and the zodiacal light (sunlight reflected from interplanetary dust). In addition, the astronaut would detect a glow along the horizon itself, as in the illustration. 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. But no one really knows for certain the cause of the glow. (Cowen, R.; "On the Horizon: Clementine Probes Moon Glow," Science News, 145:197, 1994.) Reference.

"On the early morning of 1994 January 18, a very bright luminous object crossed the sky of Santiago de Compostela, Spain. From visual sightings, it is concluded that the object wasn't a meteoric fireball (bolide). A surface "crater" in Cando (close to Santiago) with dimensions 29 x 13 m and 1.5 m deep was later discovered within 1 km of the projected "impact" point of the luminous object. At this site, in addition to the topsoil, full-grown pine trees greater than 20 m high were thrown downhill over a nearby road, leaving the downslope edge of the "crater" untouched and with a steep interior wall (this would not be the case if a regular landslide were responsible for the transport). Standing trees below the "crater" showed embedded soil and plant residues up to heights greater than 3 m. No strange materials (meteorites or artifacts) were recovered in or close to the "crater"; all materials belonged to the site and were not shocked; thus an impact is very improbable.

"At about 2240 UTC, the observers saw a strange effect in the sea stretching for approximately 100 m from the parallel body. It was a soft white light, almost strobe-like in character that pulsed irregularly. The light was bright enough to illuminate the wheelhouse deckhead and seemed to emanate from below the water, almost as if something was shining a spotlight upwards, shimmering and twirling: psychedelic projections of the 1960s were brought to mind. Curiously, the wash from the bow was not illuminated and appeared normal, likewise the wake." The phenomenon lasted for 6 or 7 minutes, faded, and then reappeared briefly.

Podkletnov discovered this amazing effect when researching superconducting materials, However, he used only a single ring, which resulted in a 2% weight reduction. Since antigravity effects are probably additive, it seems reasonable that fifty rings will create a 100% weight reduction.

These mammals are effectively toothless for predatory purposes. In fact, some marine biologists speculate that they secure their slippery prey by suddenly vacuuming them up by actuating a pumplike tongue. (AR#2 ) But how do the beaked whales find their prey in the first place? With their sonar, of course. But these superbly streamlined animals lack the huge external ears of the sonar-using bats. How do they detect the weak echoes bouncing off fleeing fish? P. Zioupos and J. Currey, at the University of York, have drawn attention to the rostrum bone that forms the beaklike upper jaw of Blaineville's beaked whale. At 2.7 grams/cubic centimeter, this bone is 50% denser than the average mammalian bone. "The bone also turned out to have unique chemical properties. It contains 35 per cent calcium by weight -- 13 per cent more than the highest value known previously. Using microscopes, the team showed that the bone is riddled with tiny tunnels. containing highly concentrated minerals." The channelled nature of this bone make it very brittle, making it unlikely that it is used as a ram in mating bouts.

Tests used modern forensic methods and were repeated many times under carefully controlled conditions.

The underlying premise is that the peoples who constructed Stonehenge, Avebury, and other megalithic sites had a penchant for aligning them, even when they were separated by many miles. Exactly why anyone would wish to go to such trouble escapes the modern mind. American archeologists generally eschew ley hunting, but S. Lekson, from the University of Colorado, was surprised to find that three important Anasazi sites in the Southwest are actually aligned with high precision along Longitude 107 57'. The three sites are: Aztec Ruins and Chaco Canyon (New Mexico) and Casas Grandes (Mexico). Even though the first and last are separated by about 450 miles, all sites are within 1 kilometer (5 /8 of a mile) of the north-south line. Lekson maintains that an alignment this precise cannot have happened by chance. How could the Anasazi have achieved such an accurate alignment over such rugged terrain? It would not be easy even with modern transits. (Cohen, Philip; "One Dynasty to Rule Them All," New Scientist, p. 17, December 14, 1996.) Comment.

Because chromosomes are composed of genes and their DNA -- the information carriers of inheritance -- it reasonable to suppose that they are the "dance-masters." This expectation is enhanced if one holds that the genes are "selfish;" that is, they have their own evolutionary agendas, and all life forms exist only to execute their "will." But cell division would not occur at all without the action of the cell's bipolar spindle. This spindle is composed of microtubules -- rods of the protein "tubulin." Somehow , when cells are about to divide, they synthesize these microtubules, which then seem to organize themselves into orderly arrays (the bipolar spindles). Then, the microtubules sort out and separate the two sets of chromosomes required for the two new cells. So, far, our description conforms to what biologists have known and accepted for decades; but there is something more mysterious going on. In 1996, researchers discovered that they can actually substitute DNAcovered beads for the chromosomes, and the microtubules will still go through the motions of sorting and separating the chromosome-less strands. Actually, the microtubules will perform their act even without the DNA-covered beads. In a sense, the bipolar spindle is a puppetmaster, and the ...

"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."

These blocks range up to 7.6 meters (25 feet) in size and weigh many tons. No native rocks in the area match them. The Ice Age glaciers never reached Arkansas, so they can't be glacial erratics. Where did they come from? One clue is the presence of glauconite in the sandstone. Glauconite is common in marine rocks, so suspicion points toward the Gulf of Mexico. Geologist G.

Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm ...

On that day thousands of homing pigeons were released by their proud owners in widely separated locations expecting they would quickly race home to their lofts. Few made it. In three separate races in New York and Pennsylvania, a total of 4,000 birds were released on October 5. Only 400 returned home. 3,000 pigeons released in California on the same day are still missing. All over the planet, homing pigeons are not homing as well as they used to. Performance has been falling steadily over the past two decades. The favorite theory blames geomagnetic storms, but no such correlation has been shown. Microwaves are fingered next. Cell phones and satellite communications fill the atmosphere ever more densely with microwaves that may throw off the navigation equipment of homing pigeons, but this hasn't been demonstrated yet either.

(The Gaia Hypothesis asserts that the biosphere acts in ways that maintain environmental conditions favorable to the existence of life.) In his letter, A. Longhurst wonders whether the earth's biosphere acting as a whole -- Gaiafashion -- may have erred in creating an environment conducive to the evolution of intelligence. It is is not clear, he says, that the sentient part of the biosphere (meaning "us") can develop enough self-control to reverse global warming, pollution, etc. He concludes as follows: "In short, is intelligence a pathogen to which the biosphere can adjust, or is it terminal?

I propose to strap buttered toast to the back of a cat; the two will hover, spinning inches above the ground." There is a deep profundity in this arrangement. S. Voss recognized immediately that a perpetual motion machine had been proposed. He set out to find a flaw. Somehow, energy was being supplied to keep the cat-toast armature turning. Voss observed that any practical cat-toast motor would have to be suspended over a very expensive carpet, for the simple reason that the probability of the toast landing buttered-side down is well known to be proportional to the cost of the carpet. (Linoleum is very poor in this application.) Furthermore. to maintain the machine's efficiency, the rug would have to be frequently cleaned of falling cat hairs. Carpet cleaning is energy-intensive, and it is here that energy must be supplied, thereby nullifying the perpetual-motion claim! (Anonymous; New Scientist " ...

Although its shoreline in complex, there is a deep channel about 2 kilometers wide with steep sides running lengthwise along the lake floor. When wind blows across the lake's surface, wind-drag pushes surface water downwind. When the wind stops or changes direction, the piled-up water is freed, and standing waves are set up as the water sloshes back and forth in the lake basin. These waves are called "seiches." Lakes usually have characteristic periods of oscillation. For Lake Champlain, it is 4 hours, with amplitudes measured only in centimeters on the surface of the water. What makes Lake Champlain of more than usual interest is the presence of a second seiche, an internal phenomenon not visible on the surface. In the summer, Lake Champlain is stratified with a thermocline separating a layer of warm surface water from much colder deep water. You can only "see" the thermocline if you lower a thermometer into the water. This thermocline also exhibits seiches, but they are startlingly different from those on the surface. In Lake Champlain, the period of the internal seiche is 4 days rather than 4 hours. The amplitudes fall between 20 and 40 meters instead of being in the centimeter range. Just a few meters ...

Newcomb had noticed that books of logarithms in the libraries were always much dirtier at the beginning. Hmmm! Were his fellow scientists looking up the logarithms of numbers beginning with 1 more frequently than 2, 3, etc.? It certainly seemed like it. He formalized his suspicions in a conjecture: p = log10 (1+ 1/d ) Where p = the probability that the first significant digit is d. This (unproven) equation states that about 30% of the numbers in a table or group will begin with 1. Only about 4.6 % will begin with 9. This result certainly clashes with our expectation that the nine digits should occur with equal probability. Fifty-seven years later, F. Benford, a GE physicist, unaware of Newcomb's paper, observed the same dirty early pages in the logarithm tables. He came up with exactly the same conjecture. Benford didn't stop there. He spent several years collecting diverse data sets -- 20,229 sets, to be exact. He included baseball statistics, atomic weights, river areas, the numbers appearing in Reader's Digest articles, etc. He concluded that his (and Newcomb's ) conjecture fit his data very well.

A casual observer of this huge earthen structure could only conclude that such immense labor was undertaken for some social imperative, such as worship or sacrifice. Perhaps this was the case in North America, but deep in the South Pacific, just east of Fiji, on the islands of Tonga, native peoples scraped large mounds of earth for what seems to be a frivolous purpose: pigeon-snaring ! But bear in mind that carnivory on these romantic Pacific islands was difficult because large game animals were nonexistent. Captured enemies helped solve the protein problem, but pigeons were much more common, and some species were good-sized and delicious. So much so that eventually only island royalty was allowed to catch and eat them. Pigeon poachers were whipped or executed (and maybe eaten?) In fact, pigeon snaring became a royal sport. To this end, starting at least a thousand years ago, the king's loyal subjects grubbed up the thin island soil and piled it up into high mounds. Tonga's pigeon-snaring mounds did not compete with Monk's Mound sizewise, being at most 115 feet in diameter and perhaps 15 feet high. But ...

To this classical neutrino problem has been added the discovery that the solar neutrino flux varies in ways difficult to explain. P. Sturrock and G.

For high hydrodynamic performance, their bodies must be nicely streamlined. For males, this means that their testicles must be stored internally. But dolphins are very active animals, and their muscles generate considerable heat -- too much heat for sperm to survive without some sort of special cooling system. (Recall that human males with undescended testicles may become sterile.) Since dolphins are obviously procreating, evolution must have come to the dolphins' rescue. Evolution's engineering solution installs heat exchangers in the dolphins' tails and dorsal fins. Blood heated in the vicinity of the testes is pumped through special veins in the tail and dorsal fin, where it is cooled by seawater and then returned to the dolphins' heat-sensitive innards. Female dolphins have similar heat exchangers to cool their uteri. The same article in Discover points out still another remarkable adaptation conferred on dolphins: They do not have to expend a lot of energy in diving to great depths. Below about 70 meters, the water pressure collapses their lungs so that they sink like rocks! Of course, returning to the surface does require some exertion.

Our climate, atmospheric oxygen level, ocean composition, and similar vital conditions are kept livable by life's waste products, such as the oxygen emissions of plants. That something like Gaia is required is seen in the extreme disequilibrium of the earth's atmosphere compared to the near-equilibrium of the atmospheres of apparently lifeless Venus and Mars. For example, our atmosphere's 21% oxygen, a highly reactive gas, is many orders of magnitude higher than one would expect on a lifeless planet. Furthermore, life-friendly conditions have been maintained for billions of years despite large changes in the sun's output and the traumas of asteroid impacts. T.M . Lenton, writing in Nature, asks a salient question: How has planetary self-regulation (Gaia) been established and maintained by evolution and natural selection which operate on the level of individuals? In other words, evolution tells us that organisms should evolve so as to leave the most progeny not so as to regulate the atmosphere. Lenton answers that there must be feedback loops from the planetary environment that steer the evolution of individuals in the "proper" direction. Lenton goes on to explore some of these many feedback mechanisms; one obscure loop involves the production of dimethyl sulfide by marine phytoplankton. Truly, it ...

As travelers can attest, the warmer regions of our planet offer the spicier foods. In a way, this observation is a proof of microevolution. The "fitter" people (that is, "survivors") in hotter climes are those who have inherited a taste for hotter foods. Spices contain chemical compounds that inhibit or kill the bacteria and fungi that are more likely to poison foods where ambient temperatures are higher. Eaters of spicier foods are more likely to survive in these areas. This is not just a surmise. A study of 4578 recipes from 93 cookbooks from all over the world have been analyzed for spice content. Sure enough, the hotter the climate, the more recipes using spices and the hotter the spices used.

At least that is what is supposed to happen. Four far-flung spacecraft, (Pioneer 10, Pioneer 11, Ulysses, and Galileo are experiencing a mysterious decelerating force not encompassed by the Law of Gravitation. It's a tiny force, but it seems to be real. Making it even more puzzling is the fact that it is decreasing according to the inverse of distance from the sun rather than the inverse square. Is it a non-solar force? Is it "new" physics? Or maybe just an artifact of the spacecraft and ground-based equipment? The fact that four spacecraft feel its tugging suggests the force is real. But the motions of the distant planets do not seem to be affected by it. So, everyone is perplexed. (Schilling, Govert; "Spacecraft Motions Puzzle Astronomers," Science, 281:1581, 1998.

UFOs are connected somehow. Or, more recently, they must be associated with the infamous crop circles! These ponderously rotating ice discs have also caught the attentions of scientists, who have been able to dispel some of these wild speculations. One well-observed ice disc formed on the Pite River in northern Sweden in 1987. It was rotating in a circular hole in the ice covering the rest of the river. "The rotating ice disc had a diameter of 49m [just over 160 feet] while the hole in the ice was 54m in diameter. The time of one full rotation was measured at 545s and 575s on 20 and 24 January respectively. Unverified measurements suggest that the time of rotation had been about 8 min a few weeks earlier. The rotation of the ice disc was anticlockwise and for most of the time the disc was in contact with the border ice. This contact point moved clockwise, i.e . the ice disc was not 'rolling' on the walls of the hole. This erosion by contact, which caused a low-frequency sound, explains why the hole in the ice was kept open for months." The ice thickness was 0.43m. Estimated weight of the ice disc = 864 metric tons -- ...

Davidovits' claim that the stone blocks of the Giza pyramids are actually made from a limey cement and poured on-site. No long-distance hauling and lifting into place required! We have since found (serendipitously) an authoritative refutation of Davidovits' claim. K.D . Ingram et al analyzed stone samples from the Giza pyramids using scanning electron microscopy, electron diffraction by X-rays, powder X-ray diffraction, inductive coupled plasmography, Fourier-transform infrared spectroscopy, and other techniques. Their conclusion: ". .. the pyramids are made of limestone and are not cementitious in nature." (Ingram, Kevin D., et al; "The Pyramids -- Cement or Stone?"

Well, L. Frank, University of Iowa, did just that in 1986. He was duly pilloried for his trouble. But, at the 1997 spring meeting of the American Geophysical Union, Frank presented new data to back up his previous assertions. The most startling of his new evidence came from a camera aboard a NASA satellite. Time-lapse photos imaged two objects streaking into the atmosphere over Poland and Germany. Frank identified these as clouds of water molecules from disrupted icy minicomets. The clouds had expanded from the house-size minicomets to clouds 3550 miles wide, weighing 20-40 tons. Frank thinks the minicomets come from a cloud of such objects orbiting the sun from earth out to Jupiter and beyond. Why don't they evaporate in the sunlight and near-vacuum of outer space? Perhaps, thought Frank, they are protected by a thin coating of carbon. (Roylance, Frank D.; "Space Snowballs Theory Gains Credence," Baltimore Sun, May 29, 1997.

Between 3 and 4 PM, D. Quinlan was driving along Route 80. A dark line squall was approaching from the west. Quinlan observed many horizontal strokes of lightning passing from cloud to cloud. These discharges seemed to make little noise -- no loud crashes of thunder, although sounds were somewhat muffled by his vehicle. These strokes moved so slowly that their progress across the sky could be easily tracked visually. Most remarkable were three discharges that began to his right, progressed across the sky in nearly a horizontal plane, and then looped back to near their starting points, thereby completing what appeared to be a circle. (Quinlan, David; private communication, May 2, 1997.) Comment. In our Catalog Lightning, Auroras, section GLL25, we offer three cases of "meandering" lightning in which the discharges follow long, complex, looping paths. However, none of these were circular. Also, in SF#89. there is an instance of "looped" lightning that rises from cloud tops toward the ionosphere and then loops back to the cloud tops. The Catalog volume just cited is described at here .

It is generally known that you can separate fresh eggs from hard-boiled eggs by spinning them like a top. If they are hard-boiled they will spin on one of the ends. The fluid contents of fresh eggs, however, will slosh around and prevent top action. O.K .! this is not very curious, so we'll place a hard-boiled egg in a flat pan containing a thin layer of water and give it a spin. Not only does the egg spin on end but a layer of water creeps up the side of the egg. When the water is about half way up the side of the egg it breaks up into droplets and sprays out horizontally like a rotating lawn sprinkler. No mysterious forces are involved, nor are there spooky quantum mechanics effects. The major forces operating are gravity, centrifugal force, and adhesion between the egg surface and the water. As the film of water creeps up the egg, the centrifugal force increases and overcomes the force of adhesion. Then, water droplets spray outward. (Gutierrez, Gustavo, et al; "Fluid Flow up the Wall of a Spinning Egg," American Journal of Physics, 66:442, 1998.) Creating fluid corners in kitchen sinks. When a smooth column of water from your kitchen faucet hits the sink, it flows out radially. ...
