And a number of experiments are showing hints that a neutrino has a small mass and that it can oscillate from one variety to another." These experiments are not yet conclusive; and if the neutrino mass is not zero, it hardly weighs more than the grin of a Cheshire cat. But taken together, the laboratory results confirm that neutrinos are perplexing particles. Are they different entities or a single species wearing different costumes? The implications of the recent measurements are far-reaching: Physicists believe that there are a billion neutrinos around for each nucleon (proton, neutron, etc.) so that if neutrinos possess just a hint of mass, they will dominate the mass of the universe; and Measurements of solar neutrinos fall short by a factor of three of what theory says the sun should spew out. This discrepancy could be explained if the solar neutrinos change from electron neutrinos to another form during their flight from the sun to earth, for the terrestrial neutrino detectors measure only electron neutrinos.

Quite unexpectedly (at least to the conventional physicist) the mind seems able to cause such changes at will under controlled conditions. The changes are minuscule to be sure, but cause-and-effect is clear-cut according to Jahn. But don't say that psi power has now been scientifically proven. The effects vary from person to person and, for the same individual, from time to time.

Over 300 serious discrepancies are tabulated and backed by some 445 references from the scientific literature. To remove triviali-ties, only dates that were "wrong" by 20% or more were included. This criterion insured that the anomalous dates were off by one or more geological periods. To enhance his case, Woodmorappe excluded data for such troublesome minerals as K-feldspar, which have unreliable records. The surviving discordances will certainly disturb anyone who has long accepted radioactive dating as the near-final word in geochronology. The lengthy text accompanying the table delves into the geological problems posed by the tabulated anomalies, primarily the severe distortions implied in the supposedly well-established geological time scale. Many attempts have been made to explain away these discrepancies, usually by asserting that the system must have been "open"; that is, contamination and/or removal of materials occurred. But a far more serious situation exists: the reluctance of researchers to publish radiometric dates that fly in the face of expectations. Data selection and rejection are epidemic.

After 50 years, he has concluded that these colossal submarine features have no single cause. Subaerial erosion, turbidity currents, submarine slumping, and faulting have all played roles. Anomalists will be most interested in Shepard's insistence that the evidence shows that subaerial erosion has played a major part in carving out the submarine canyons. This explanation is definitely frowned upon by most geologists because the Pleistocene sea levels dropped only about 100 meters according to current thinking. How could subaerial erosion account for canyons several thousand feet below present sea level? Shepard persists; the evidence is there. The continental margins must have risen and then sank back!

Bacteria, which are usually regarded as fairly inert when it comes to responding to environmental pressures, actually react in different ways to dozens of different stimuli. This ability at the very least requires sensory equipment, internal clocks, a memory, and a decision-making capability. If bacterial activity is all preprogrammed (the reductionist view), are not humans also preprogrammed? Human programs are larger and more complex, of course, but still devoid of "thinking." Conversely, if humans really do think; that is, transcend preprogramming (free will, if you wish), then bacteria must also think. The third possibility is that at some step in the ladder of life, "higher" life forms begin to think. There is little evidence that life is split so profoundly between thinkers and non-thinkers.

Segal's chronometric theory of the cosmos, however, does predict a quadratic relationship. In Segal's theory redshifts are due to the gravitational slowing of light rather than any gereral expansion of the universe. Even if most astrophysicists are finally persuaded that the quadratic relationship is real, they will be loath to abandon the philosophically appealing Expanding Universe.

Normal galaxies seem to have masses of about 1011 times that of the sun. The unthinkable assumption suggests that every 108 years or so, these ordinary, unassuming galaxies become supermassive (about 1013 solar masses) for several million years. When the core of a galaxy becomes supermassive, its stars are tugged into tight new orbits. The subsequent switching off of the supermass allows the galaxy to expand outwards again. The author claims to have found just such expansion effects among the globular clusters in our own galaxy. His data are striking and quite convincing. The notorious "missing mass" problem of cosmology disappears with the cyclic supermass assumption because the time-averaged mass of each galaxy will be much higher than that observed in its normal enervated state. Doesn't this sudden temporary appearance of mass violate the laws of physics? No, says the author, physicists habitually assume a superfluid, superconducting vacuum state, which is the ultimate source of all mass-energy, when they develop their theories of fundamental particles.

It has long been a cornerstone of modern science, to say nothing of man's cosmic outlook, that the earth attends a modest star that shines in an undistinguished part of a run-of-the-mill galaxy. Life arose spontaneously and man evolved on this miscellaneous clump of matter and now directs his own destiny without outside help. This cosmic model is supported by the Big-Bang and Expanding Universe concepts, which in turn are buttressed by the simple observation that astronomers see redshifts wherever they look. These redshifts are due, of course, to matter flying away from us under the impetus of the Big Bang. But redshifts can also arise from the gravitational attraction of mass. If the earth were at the center of the universe, the attraction of the surrounding mass of stars would also produce redshifts wherever we looked! The argument advanced by George Ellis in this article is more complex than this, but his basic thrust is to put man back into a favored position in the cosmos.

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.

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 ...

R.G . Everit responds that this is not really mysterious. The better chess-playing computers are actually designed to behave unpredictably when confronted by several moves of roughly equal promise. This feature makes it more interesting for human players. Everit also sets us straight in the matter of computer determinacy. "However, contrary to your basic assumption, most computers (even a home PC) can be forced to behave truly unpredictably. This cannot be done using the random-number generators supplied with the software, as these depend upon some mathematical formula and so are determined in advance, even if they appear to show no pattern. But if the machine has an internal clock readable by the programmer, he can determine the machine's choice depending upon the time required for some complex calculation, which will vary according to such factors as minute voltage variations and the aging of the machine's components. For example, the CDC 3600, on which I learned to program in 1975, had an accessible microsecond clock, and my program to calculate the first five perfect numbers* required about 15 minutes of run time; the last few digits of the exact number of microseconds required to run this program each time varied quite unpredictably.

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.

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.

In some situations, though, the increase in disorder (entropy) in one part of the universe can create order elsewhere. For example, if you add tiny plastic spheres of two sizes to salty water, you will not get a uniform mixture. Instead the larger spheres will pack together into tightly ordered crystaline shapes (representing more order) while the smaller spheres become more disordered. It is like watching cream unstir itself from coffee. It smacks of magic, but it is all within the laws of thermodynamics. This strange "force" exerted by entropy may explain some puzzling biological phenomena, such as the expulsion of nuclei from mammalian red blood cells before they enter the bloodstream as sacks of hemoglobin. The idea being that the increasing entropy of the proliferating hemoglobin molecules (analogous to the smaller spheres) is maximized when the nuclei (large spheres) are squeezed out of the cells altogether.

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 is a tangled bank! All of the feedback loops imply that the evolution of life forms is constrained (or dictated) by the need to keep the planet livable and not to simply leave the most progeny, but rather the progeny that will best serve Gaia!

(SF#110) The media have said little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. 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.

Now it seems that one particle of an "entangled pair" knows instantaneously what its mate is doing, possibly even if it is located on the other side of the universe. More quantum-mechanics spookiness is seen in "tunneling" phenomena, such as that mentioned in AR#3 , where a Mozart symphony zipped through a barrier at 4.7 times the speed of light ...

Network Tierra. Here we have a network of 150 computers linked worldwide by the Internet. One objective is the exploration of structures and patterns of information that drive evolutionary processes. A key element is an artificial lifeform that begins as a "seed organism" (modeled as information, of course) that wanders at will among the different environments presented by the computers in the network. So far, these digital organisms are surviving and changing. (Blakeslee, Sandra; "Cyberlife Critters Evolving in Computer Network," Austin American-Statesman , November 30, 1997. Cr. D. Phelps. Minad Project. Begun in 1953, the Minad Project is pure futurism; that is, the prediction of where the computer revolution is taking us. The Minad Project envisioned three evolutionary stages: Wiring the world (already accomplished as today's Internet); The transformation of the network into a high-speed creative mechanism (the Technosphere); and The emergence of global hyperintelligence (the Autosphere). The Minad Project is now forecasting what this all means for non-silicon-based life in the 21st. Century. (Baker, Lance; "They're Taking Over," New Scientist, p.55, December 6, 1997.)

Science Frontiers ONLINE No. 117: May-June 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Kinky Sex Among The Invertebrates We suspect that the following two items may embarrass some, but they are too weird and amusing to ignore. Love's arrow. Or, rather, love's giant hypodermic needle. Cupid's arrows are rather benign compared with those of some squid. Some small squid will use their sharp beaks or tentacle hooks to rip open the skin of females. They then insert spermatophores with their penises. In the giant squid, however, the male's penis is formidable, muscular, and almost a meter long. It is powerful enough to insert spermatophores directly under the skin of the females. The males are not always accurate, for males themselves are sometimes impregnated in this manner during the squids' deep-sea orgies. (Norman, Mark D., and Lu, C.C .; "Sex in Giant Squid," Nature, 389:683, 1997.) The free-style penis. In the octopus and many cephalopods, the males have a special tentacle with which they insert their spermatophores under the mantle of the female. The tentacle is then retracted for future use. The male paper nautilus is more profligate with its tentacles. The paper nautilus is cephalopod which, like its cousin, the chambered nautilus, "sails the unshadowed main."* When the male detects a receptive female, he avoids intimacy. It's sex at a distance ...

... At 5:11 A.M ., crews of three trawlers at widely separated sites off south Greenland reported "a blazing fireball that turned night into day." At a distance of 100 kilometers (62 miles), the flash was compared to that from an atmospheric nuclear explosion. Danish officials dismissed the possibility of a surreptitious nuclear test. The U.S . Air Force stated that the object was neither a reentering spacecraft nor artificial space debris. Some seismic tremors also emanated from Greenland, so the impact of a large meteorite is suspected. Based on the visual sightings and a moving object caught on a parkinglot surveillance camera in Nuuk, Greenland's capital, the probable impact point is at 61 25' N., 44 26' W. Efforts to locate the meteorite will have to wait for favorable weather. The supposed meteor was not a small object. The Niels Bohr Institute in Copenhagen compared it to the Kap York meteor that fell south of Thule, Greenland, in prehistoric times. Pieces of this iron meteorite aggregating 50 tons have been collected. (Sawyer, Kathy; "Fireball a Mystery till Thaw," Charlotte Observer, December 22, 1997. Cr. G. Fawcett via L. Farish.) Three additional large iron meteorites found on Disco Island, Greenland, in 1870. Weights: 20, 10 and 5 tons. Disco Island is about 600 miles south-east of Kap York.
