American Southwest. Photomultipliers in the Fly's Eye telescopes 100 kilometers southwest of Salt Lake City recorded the havoc wrought in the upper atmosphere by the most energetic cosmic-ray particle ever measured. When this tiny subatomic particle slammed into air molecules, the ensuing debris caused the surrounding atmosphere to fluoresce. The amount of light produced indicated that this cosmic ray had an energy of 3 x 1020 electron volts -- that's equivalent to the energy of a bowling ball dropped from waist level. Now that's a lot of energy for a subatomic particle! Because cosmic rays normally lose energy as they collide with photons in their cosmic wanderings, astrophysicists believe that "the big one" had to have a recent, nearby origin in order to still be so energetic. But no one has any idea where it could have come from or how it might have acquired so much energy. Somewhere out there in nearby space there may be a natural particle accelerator orders of magnitude more powerful than our biggest earthbound atom smashers. (Anonymous; "The Deepening Mystery of Cosmic-Ray Origins," Sky and Telescope, 87:12, May 1994.) Comment. Actually, the source of "the big one" need not have been nearby and recent.

It was declared, rather imperiously, that a large asteroid had impacted the earth, causing much physical and biological devastation. Many scientific papers are still being written on this singular period in the earth's history, and the situation is no longer so clear-cut. We select for brief review four papers, each with a different perspective. Occurrence of stishovite.

The anomalies are so large that astronomers have concluded that these objects must have undergone considerable evolution after they were formed by accretion (the currently accepted mode of formation). Unfortunately these four satellites are so small that they could not have accommodated any reasonable energy source capable of causing the observed crustal evolution. The authors suggest strong local concentrations of radioactive heat generators rather than uniformly distributed radiogenic substances, such as those that helped mould the earth's surface.

Perhaps not!! "This article presents a meta-analysis of experiments testing the hypothesis that consciousness (in particular, mental intention) can cause tossed dice to land with specified targets face up. Seventy-three English language reports, published from 1935 to 1987, were retrieved. This literature described 148 studies reported by a total of 52 investigators, involving more than 2 million dice throws contributed by 2,569 subjects. The full data base indicates the presence of a physical bias that artifactually inflated hit rates when higher dice faces (e .g ., the '6 ' face) were used as targets. Analysis of a subset of 39 homogeneous studies employing experimental protocols that controlled for these biases suggests that the experimental effect size is independently replicable, significantly positive, and not explainable as an artifact of selective reporting or differences in methodological quality. The estimated effect size for the full data base lies more than 19 standard deviations from chance, while the effect size for the subset of balanced, homogeneous studies lies 2.6 standard deviations from chance. We conclude that this data base provides weak cumulative evidence for a genuine relationship between mental intention and the fall of dice." (Radin, Dean I., and Ferrari, ...

They occur in bands -- not one band but several. How can this geometry be explained. One hypothetical scenario has the primitive moon surrounded by many moonlets 60 miles and larger in diameter, plying equatorial orbits that are unstable. As the moonlets' orbits decayed, some crashed into the moon's equatorial regions, blasting out a band of huge craters. The force of the impacts also caused the lunar crust to slide over the still-liquid core by as much as 90 . When the next group of moonlets crashed, they gouged out a new belt of craters and shifted the crust still more. Magnetic measurements of lunar rocks tend to confirm that the lunar crust did indeed shift by large angles -- several times. (Anonymous; "Did the Moon Have Moonlets?" Science Digest, 92:20, January 1984.) Comment. Such events could also have happened on earth, which would account for tropical-zone fossils being found at the present-day poles.

These muffled detonations heard near the coasts of almost all the continents are believed by some to be caused by eruptions of methane from the seafloor. The same eruptions probably also account for the myriads of "pockmarks" found in the sediments of shallow seas. Whether this outgassing of methane comes from shallow accumulations of organic matter or from deep within the crust is still debated. Here, geophysics merges with biology. Recently, a group of researchers discovered a large (540 square meters) patch of chemosynthetic mussels in a brine-filled pockmark, at a depth of 650 meters, off the Louisiana coast. The mussels grew in a ring around the concentrated brine. The mussels harbor symbionts which consume the methane still seeping up through the brine from a salt diapir (a massive fingerlike intrusion 500 meters below the brine pool. The origin of some diapirs is not well-understood.) The mussels get the oxygen they require from the ordinary seawater covering the dense brine. Like the biological communities surrounding the "black smokers" and other ocean-floor seeps, the brine-filled pockmark community includes several species of shrimp, crabs, and tube worms.

Roughly a thousand cells make up its tiny body, and scientists have charted the birth and death of each cell from egg to adult. This roundworm's life is a mosaic of changing cells, as some die to make way for new cells with different agendas. Somehow this programmed sequence of cell death and birth can be slowed down by mutations and thus increase longevity. Wouldn't any mortal speculate that perhaps human longevity might, like that of C. elegans , be extended by modern gene manipulators?

... that a solution of antibodies diluted by a factor of 10120 can still trigger a strong biological response from basophils (a kind of white blood cell). Now, 10120 is such an incredibly large number that it is extremely unlikely that even one antibody molecule could be present in the diluted activating solution. Nevertheless 40-60% of the basophil cells reacted. So unbelievable are the reported experimental results that the editors of Nature felt compelled to add an "Editorial Reservation" stating that, "There is no physical basis for such an activity." This is all great stuff. The original French work was duplicated by six other laboratories in France, Italy, Israel, and Canada. What makes it even more fun is the homeopathy connection. Homeopathic medicine is based on the theory that substances causing the symptoms of a disease in a healthy person can cure a sick person displaying these symptoms, providing the dose administered is vanishingly small. Science strongly and passionately debunks homeopathic medicine. The Editor of Nature thinks that there must be a systematic error somewhere. Other scientists suggest that, perhaps, somehow, the antibodies left an "imprint" on the diluting water molecules.

Siam 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.

'Sometimes it gets so loud you have to talk above it. It can drown out conversations and wake people from a dead sleep.' For reasons no one understands, the noise can be heard only from about 8 p.m . until sunrise, and it goes silent from late September until mid-April, when it begins humming again through the summer."

It propagates itself by turning blueberry leaves into whitish, bell-like structures resembling true blueberry flowers.

The transferred spores infect other blueberry plants, causing them to produce white mummy-berries rather than blueberries. When spring comes round, the fungus-filled mummy-berries release the fungus to the leaves, and the cycle continues.

Did you know that the platypus bill is a finely tuned instrument with approximately 850,000 electrical and tactile receptors? These are far more sophisticated than those found in fish. When the platypus goes foraging underwater, a furry groove closes, covering its eyes and ears, and the nostrils on the bill are sealed shut. It becomes a high-tech predator -- despite all those snide remarks about its primitive nature. The poison spurs on the back legs of the male platypus are nothing to fool around with. They can cause humans severe pain and weeks of paralysis. And a dog can lose its life when a platypus clamps its legs around its muzzle and drives in its spurs. But, ask evolutionists, how did this poison apparatus get on the hind legs? The supposed ancestors of the platypus, the reptiles, modified their salivary glands for venom delivery. How did the platypusses break from this evolutionary mold and innovate? It's not consistent with the text! The fossil record reveals that a platypus-like creature lived long before the Age of Mammals. These early platypusses had teeth in the adult phase, whereas their modern relatives replace their baby teeth with horny plates -- another innovation. Therefore, far from being a hodgepodge of parts left over from bird and reptile evolution, the platypus has actually pioneered several zoological ...

"Due to an unknown cause, certain of the prints once labeled human are taking on a completely different character. The prints in the trail which I have called the 'Taylor Trail,' consisting of numerous readily visible impressions in a left-right sequence, have changed into what appear to be tridactyl (three-toed prints, evidently of some unidentified dinosaur. The changes in the impressions themselves are mostly confined to lengthening in the downriver direction. The most significant change, however, is that surrounding the toe area. In almost each of the prints in the trail, three large 'toes' have appeared, similar to nearby dinosaur tracks. These toes, typically, are coloration phenomena only, with no impressions, in most cases. Frequently the 'mud pushup' surrounding the original elongated track is crossed by this red coloration.

Some physical scientists claim rather imperiously that the dinosaurs and many other species were done in by the impact of a huge asteroid/meteorite. The worldwide iridium spike is conclusive, they say. Many paleontologists and geologists, however, remain unconvinced and prefer widespread volcanism. We have already covered the various arguments in past issues of Science Frontiers; here, we want to advise our readers that a pair of excellent articles by principals in this debate have appeared in Scientific American. Generally speaking, it seems that the proponents of the impact theory are now listening to the other side. For example, multiple impacts are now proposed to account for evidence of the type introduced below. (Alvarez, Walter, and Asaro, Frank; "An Extraterrestrial Impact," Scientific American, 263:78, October 1990. Also: Courtillot, Vincent E.; "A Volcanic Eruption," Scientific American, 263:85, October 1990.) A spike dulled. The case for a single asteroid/meteorite impact has been weakened by a recent reexamination of the classic exposure of the CretaceousTertiary boundary at Gubbio, Italy. Here, the discovery of an iridium "spike" at the boundary was thought to betoken a sudden, catastrophic, extraterrestrial event. On further ...

... comets come in cycles?Only a few years ago, geologists refused to recognize any terrestrial meteor craters larger than Arizona's Meteor Crater, which is merely a mile or so in diameter. Now, we have a long list of craters or astroblemes (star wounds), some of which measure hundreds of miles across. In fact, there are enough large dated crters so that some scientists have taken up a time-honored human pastime: Looking for cycles or periodicities in the data. (Humans can find cyclicities in almost any collection of data!) To be more specific, some have claimed that large meteor craters come in clusters dated 28-31 million years apart. These catastrophic events have been correlated with biological extinctions, magnetic field reversals, and basalt flooding. The astronomical causes of this supposed periodicity range from the solar-system's crossing of the galactic plane, to the perturbations of an unseen solar companion, to regular perturbations of the Oort cloud of comets that is thought to hover at the fringe of the solar system. In short, a large, interlocking edifice of geological and astronomical speculation has been erected upon a foundation of terrestrial crater ages. But how well do we really know the ages of these craters? How complete is the cratering record? The answer to the first question is: "Not well at all." Further, we can be certain that many craters still lie undiscovered beneath sediments. In addition, most meteors/comets splashed into the oceans, leaving no record at all. An updating of the most recent crater data ...

The search has revealed that at six times during the last glaciation, huge armadas of icebergs launched from Canada spread across the northern Atlantic Ocean, each triggering a climate response of global extent." The foregoing abstract does not mention the interesting Heinrich layers that fostered the above scenario. In 1988, H. Heinrich published a paper describing a curious set of sedimentary layers found in cores drilled in the tops of the Dreizack seamounts in the eastern North Atlantic. Heinrich concluded that each of the six layers he found represented the melting of "six great armadas of icebergs." These icebergs carried debris picked up in Canada and, as they melted, deposited it on the seamounts and ocean floor. Each layer could be correlated with the major climate boundaries revealed by the Greenland ice cores. Very fittingly, these iceberg incursions are now termed "Heinrich Events."

What caused this population "bottleneck"? Did a population crash engulf the entire globe. If not, who was spared? Such questions arise from a surprising observation: Human DNA is remarkably uniform everywhere humans are found. This hidden genetic uniformity is difficult to believe if one strolls through a cosmopolitan city like New York or Paris. Nevertheless, compared to the DNA of the great apes, whose mutation rates should be close to ours, human genes on the average show far fewer mutations. Human DNA from Tokyo and London is more alike than that from two lowland gorillas occupying the same forest in West Africa. Harvard anthropologist M. Ruvolo has commented: "It is a mystery that none of us can explain." The clear implication is that humans recently squeezed through a population bottleneck, during which many accumulated mutations were wiped out. In a sense, the human race began anew during the last 400,000 years. Unfortunately, DNA analysis cannot say where the very grim reaper came from.

Now, quasar 4C29.45 comes along and pulsates on time scales of 30 minutes and less. These pulsations are sharp and not spread out timewise, implying that quasar 4C29.45 must be smaller than 30 light-minutes in size -- otherwise the disturbance causing the pulsation would have to travel faster than light. On the night of April 10, 1981, the situation (already bad) worsened, when brightness jumps of 0.2 magnitude occurred nearly instantaneously. Conclusion: quasar 4C29.45 may be only lightseconds in diameter, which should really by physically impossible.

Sepkoskiand and D. Raup, two researchers at the University of Chicago, have drawn up graphs showing the numbers of families of marine organisms that have vanished from the fossil rec ord over the eons. From this overview of manifest mass extinction emerged a puzzling and potentially profound pattern. Roughly every 26 million years over the last 250 million years, the number of extinctions jumped well above the background level. Some cyclic phenomenon seems to have been killing off life forms on a systematic basis. But no natural 26-million-year cycles are known although meteors and comets are favored causes of mass extinctions these days, they display no such cyclic period. (Simon, C.; "Pattern in Mass Extinctions," Science News, 124:212, 1983.) Comment. Instead of looking outward to astronomical catastrophism, perhaps we should look inward. The earth itself may undergo cyclic paroxysms; or life might undergo intrinsic phases of decline and rejuvenation. Periodic events in the evolutionary time scale.

As wind moved air through the heaps of stone, the day's cycle of rising and falling temperatures caused moisture to condense, run down, and feed a network of clay pipes.

However, not a word about the detonations appeared in most of the scientific publications we regularly monitor, with the exception of the British New Scientist and a recent article in Science, 199:1416, March 31, 1978. Comment. The detonations were rather strong, shaking houses and even causing picture windows to fall out. In some instances, flashes of light and other luminous phenomena were reported. The sounds were characterized as "air quakes" by some scientists because they did not always register on seismographs, although they were usually recorded on air-pressure monitoring equipment.

Seismic noises come to mind next, but the frequent failure to register the events on seismographs suggested an atmospheric phenomenon.

From these, we select four for your delectation. New laboratory experiments suggest a slightly non-symmetric behavior of matter and anti-matter that might explain the dominance of matter in the universe. But it creates a new mystery---why this asymmetry should exist. Distant supernovae have a rise time of 10-15 percent faster than nearby type supernovae. This throws doubt on their use as standard candles, and on the interpretation that the expansion of the universe is accelerating. Interestingly, the amount of the discrepancy is close to the size of the special relativity time dilation factor, gamma. If the cause of the red shift were something other than velocity, then no time dilation factor would be applicable, and this discrepancy would disappear. Evidence for water on Mercury implies a rapid-acting, exogenic water source, consistent with the exploded planet hypothesis expectations. Reasonable escape rates imply that deuterium on Venus is from a relatively recent water source. (Van Flandern, Tom; "Highlights of the Latest EME," Meta Research Bulletin, 8:64, no. 4, 199.

A feline friend has just ambled across your keyboard. In a worst-case scenario, cat curiosity may have caused your computer to crash. It is urgent and imperative that you install a program called "PawSense" that can detect pawprints -- and -- block further inputs. PawSense will also post the message: "Cat-Like Typing Detected." It will in addition generate sounds known to be very annoying to cats. You can regain control of events by typing the word "human." Sure, this is all pretty funny, but just how does a computer distinguish between paw-generated input and the gibberish present in e-mail addresses and the like? The rationale behind PawSense recognizes that cat paws are so broad that they actuate groups of adjacent keys simultaneously.

Science Frontiers ONLINE No. 26: Mar-Apr 1983 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Punching A Hole In The Asteroid Hypothesis Scientists have long searched for a cause for the profound geological and biological changes that apparently occurred between the Cretaceous and Tertiary periods. When an iridium-rich layer was found in several areas at this important boundary, many claimed it as proof of an asteroid impact or some other catastrophism that would nicely explain the massive worldwide changes that occurred. With this preamble in mind, consider the following abstract from an article in Science: "Analyses of the clay mineralogy of samples from the Cretaceous-Tertiary boundary layer at four localities show that the boundary clay is neither mineralogically exotic nor distinct from locally derived clays above and below the boundary. The significant ejecta component in the clay that is predicted by the asteroid impact scenario was not detected."

Science Frontiers ONLINE No. 131: SEP-OCT 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Green Misconceptions More trees are better for the environment . The Kyoto protocol recommends that we should all plant more trees, because trees help remove carbon dioxide from the atmosphere. CO2 is a green-house gas, and its reduction should slow global warming. At least, this is how the Kyoto logic went. More trees may be good for the environment in the tropics, but the reverse is true in lands that are covered with snow most of the year. This is be-cause snow reflects much of the impinging solar energy back into space. If these northern lands were heavily forested, much of the solar energy would be absorbed and converted into heat. Climate-modellers confirm that sunlight-reflecting snow is better for the environment than trees. (Anonymous; "Reflect on It," New Scientist, p. 19, May 13, 2000.) Hydroelectric power is clean . Although widely proclaimed to be among the cleanest energy sources available, some hydroelectric powerplants actually con-tribute more greenhouse gases than large coal-fired plants! Submerged vegetation is the problem. When it decays, it releases greenhouse gases---in quantity. The forests first submerged by the reservoirs behind the dams contribute gases for only a few years. Most of the troublesome biomass is fed into the reservoirs from upstream. Compounding the problem are the vast areas of stagnant water behind many hydroelectric dams. There, in the absence of ...

Science Frontiers ONLINE No. 133: JAN-FEB 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects What's Up There?Some Leonid meteors are not behaving the way meteors should. They begin to burn up well above 100 kilometers where the atmosphere is too thin -- essentially a good vacuum -- to cause frictional heating and consequent vaporization. We mentioned this conundrum briefly in SF#125. We now have the scientific details at hand concerning the supporting observations made during the November 1998 Leonid bombardment. The observations were made by an international team in China. Photographic cameras were employed as well as an all-sky TV camera equipped with an image intensifier. All photographed meteors began to visibly burn up below 130 kilometers, but the TV camera consistently picked up the same meteors at higher altitudes. Both sets of cameras recorded the same final burn-up heights. The most startling observation was a meteor that the TV camera detected at roughly 200 kilometers altitude. The highest observed Leonid meteor with initial mass of about 1 kg started radiating at an altitude of almost 200 km. The origin of meteor radiation at such high altitudes is still not well understood and more detailed observations will be needed, including near-infrared spectroscopy.

Science Frontiers ONLINE No. 96: Nov-Dec 1994 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Lunar Crater Chains The recent breakup of comet Shoemaker-Levi 9 into a long procession of fragments that subsequently crashed into Jupiter (SF#95) causes one to wonder whether similar events have occurred elsewhere in the solar system. On bodies with solid surfaces, the impacts of such processions would likely result in chains of craters. Jupiter's moon, Callisto, in fact, displays a dozen or so crater chains that might be attributed to processions of projectiles. The crater chain on the floor of the lunar crater Davy (Nasa) How about our own moon? H.J . Melosh and E.A . Whitaker have studied the close-up lunar photos and found two good candidates. The more spectacular lunar crater chain stretches 47 kilometers across the floor of the crater Davy. This chain consists of about 23 pockmarks each measuring 1-3 kilometers in diameter. A similar, more degraded chain is found in the crater Abulfeda. Melosh and Whitaker suggest that: ". .. the Davy and perhaps the Abulfeda chains were created by tidally disrupted 'rubble pile' asteroids." (Melosh, H.J ., and Whitaker, E.A .; "Lunar Crater Chains," Nature, 369: 713, 1994.) Comment. It is only natural to ask if the earth itself also bears the scars inflicted by similar processions of celestial debris. In SF#80, we described one ...

And these hailstones really do resemble this favorite candy. There was more than a bagful of them; they came down in a fusillade of millions, as related by A. Wills. A neatly sculpted conical hailstone. One of millions that recently fell in Wales. Were they aerodynamically shaped? During a recent hailstorm in Wales, I was surprised to see that all the hailstones were conical. Each one had an apex angle of about 75 , with a flat or slightly curved base about 4 millimeters across. What caused this? Is this shape common, and is its similarity to an Apollo re-entry capsule coincidental? (Wills, A.; "Hail Capsules," New Scientist, p. 121, March 24, 2001.) Comments. Actually, conical hail is more common than you might think. See GWP in Tornados, Dark Days... for many examples. How conical hail forms in such prodigious quantities and in such geometric perfection in the maelstroms of violent storms is unknown. The morphological similarity to the Apollo reentry vehicle is almost certainly coincidental. Droplets of liquid rock that reenter the earth's atmosphere are molded into buttons, spheres, and other shapes to create tektites. We do not know of any conical tektites.
