North Atlantic Ocean. Aboard the m.v . Waterford enroute from Pto Bolivar, Columbia, to Ijmuiden. At 1832 UTC an azimuth of Jupiter was taken shortly after sunset. The sky in the vicinity of Jupiter was completely clear, no cloud of any type, with but a few small cumulus dotted around the horizon. About five minutes later, having completed the calculations, the observer again looked out to see a ribbon type cloud, broken in formation, stretching almost from [the] eastern horizon to [the] western horizon. If the estimated height (see below) is reasonably correct, then the bandwidth couldn't have been more than a few hundred feet, apparently more cigar-shaped in cross section than flat, the maximum axis being horizontal, the minimum vertical. The cloud was fairly consistent in density, and at a fairly stable altitude, not undulating or rippled, having the consistency of a small cumulus cloud (white and fleecy), but also translucent. Initially, it was thought to be a condensation trail, but this was shortly dismissed as it was considered too low (estimated to be less than 10,000 ft altitude, probably around 7,0008,000 ft). Both ends of the cloud were checked with binoculars but no aircraft was evident; however, as a yardstick, and by good fortune, one did appear ...

... Sometimes, though, it seems like the illness strips away barriers and reveals hidden or suppressed talents, as seen in the two dementia patients described below. One 53-year-old man, a car stereo installer with a 10th-grade education and no prior interest in art, suddenly began painting. At first, he drew simple still lifes of vases and bridges. But his work became increasingly sophisticated. Eventually, he was painting Indians, churches and haciendas recalled from distant memories of his youth. Similarly, a 51-year-old housewife who had never had artistic training took up painting. She initially created unsophisticated images of rivers, ponds and rural settings; later, elaborate and sometimes eccentric versions of the works of great masters. Unfortunately, such new-found talents are short-lived. They, too, deteriorate. (Stein, Rob; "Patients' New Gift Paints Clearer Image of Disease," The Brain in the News, p. 7, October 30, 1998. Cr. J.

The species P. chapmani builds low mounds of pebbles over its burrow systems, and P. hermannsburgensis may use these mounds after they are constructed. The pebbles are of a uniform size and cover a large area, often a meter in diameter. The pebbles are probably collected both by excavation and from the surface. Some local mammalogists believe these are used as dew traps. Since the air around the pebbles warms more rapidly as the sun rises than do the pebbles themselves, dew forms on the pebbles by condensation. As the areas in which these mounds are found are quite dry, except after a heavy rain, these dew traps solve the problem of water shortage. Local farmers use the many pebble mounds for mixing concrete. It is believed that the ancient people of the Mediterranean region used a dew trap method comparable to that of P. chapmani ."

... Psychosomatic Medicine: "This study of deaths from natural causes examined adult mortality around the birthday for two samples, totalling 2,745,149 people. Women are more likely to die in the week following their birthdays than in any other week of the year. In addition, the frequency of female deaths dips below normal just before the birthday. The results do not seem to be due to seasonal fluctuations, misreporting on the death certificate, deferment of life-threatening surgery, or behavioral changes associated with the birthday. At present, the best available explanation of these findings is that females are able to prolong life briefly until they have reached a positive, symbolically meaningful occasion. Thus the birthday seems to function as a 'lifeline' for some females. In contrast, male mortality peaks shortly before the birthday, suggesting that the birthday functions as a 'deadline' for males."

There is no pattern, gamma-ray bursters seem to be evenly distributed in all directions. This is not what the astronomers expected, and the implications of this isotropy are staggering. Gamma-ray bursts emanate from highly localized unseen sources. They may last for a few milliseconds or stretch out for several minutes. The energy in the bursts ranges over 26 orders of magnitude. The rise-times of the bursts are so short that the sources can only be a few hundred kilometers across. Before the accompanying map appeared, most scientists thought that the bursters were nearby, probably in the disk of the galaxy, and were due to asteroids being digested by neutron stars or possibly neutron-star quakes. If such were so, the bursters would be concentrated in the plane of the galaxy (the Milky Way), which clearly they are not. Another theory places the bursters in a distant spherical halo about our galaxy. But, in this case, the bursters would have to be much more energetic than astronomers care to contemplate. In fact, if they exist in a galactic halo, we should also be able to detect the bursters in our neighboring galaxies -- but we do not! A more exciting ...

Sounds interesting, but is there any basis for thinking such a sophisticated gadget could have evolved? It seems that some experiments with newts by J.B . Phillips and S.C . Borland support the idea. The newts were first trained to orient themselves in a certain direction with respect to the geomagnetic field. "When tested under one of four artificial field alignments (magnetic north at geographic north, east, south or west), the newts kept their training directions constant relative to the magnetic rather than the geographic system of reference, but they selected different angles with respect to the magnetic field when they were illuminated by either short (about 450 nm) or long-wavelength light (about 500 nm). When tested under 475-nm light, or in the dark, they were completely disoriented." The experiments demonstrated that light was crucial to the newts' magnetic sense, and that photoreceptors had to be involved.

Females of these species usually survive to breed a second and even third year. The poor males, however, succumb due to "elevated levels of free corticosteroids in the blood and associated disease such as hemorrhagic ulceration of the gastric mucosa, anemia, and parasite infestation." In short, they seem programmed to die after mating, like the male octopus. And one wonders why evolution has wrought this mass die-off. In their studies of marsupial mice, C.R . Dickman and R.W . Braithwaite have extended the phenomenon to two new genera: Dasyurus and Parantechinus . They have also found that the phenomenon is a bit more complex.

We will try to stock at least one of these books, but it will be a few months before can can get them on this side of the Atlantic. Meanwhile, a review of the two books in New Scientist provides some information beyond that already presented in several past issues of SF. First, the crop circles, spanning 5 to 20 meters, are incredibly precise and sharp. Flattened stems on the periphery of a circle almost touch erect, undamaged stems. The so-called satellite circles that sometimes array themselves around the main circles may be connected by a narrow ring, thus: Even more curious, a short radial spur extends outward from some circles, so that from the air the circle resembles a fat tadpole. In his book, G.T . Meaden, the Editor of the Journal of Meteorology, U.K ., presents his theory of how the circles are incised in field crops: "He describes the clues that have enabled him to point to the circles being formed by the impact of a body of fast-spinning air that has been partially ionized. He explains how a columnar atmospheric vortex, with a vertical or inclined axis, provides the channel for the formation of a plasma (ionized gas) vortex and for its conduction towards the ground. The ionisation of the air ought to be sufficient to make the vortex luminous at night and the fast spin may make the ...

Before disappearing from sight, however, he began to rock back and forth. I followed, trying to stay just close enough to see what he was up to without disturbing him. Fortunately, he did not scare easily, which allowed me to approach within a few yards as he meandered, walking and rocking. First, I noticed that the rocking was caused by short bouts of stomping with the front feet, alternating between left and right. Then he suddenly jabbed his head at the ground and ate something.

Eruptions of Old Faithful Geyser are generally perceived as extremely regular events, with variation of eruptive interval being attributed to random noise. The governing equations for such a hydrothermal system are highly non-linear, therefore it is reasonable to assume that such systems are capable of operating in regines that display chaotic behavior. Three-dimensional state-space reconstruction of eruption time data provides strong evidence of a strange attractor quite similar to the Rossler attractor. Establishing the system as chaotic indicates that while one can predict eruptive intervals in the short term, long term predictions regarding Old Faithful's eruptive behavior are impossible, no matter how carefully and accurately the system is modeled. The mean eruptive interval of Old Faithful has changed over time. This is consistent with the behavior of a chaotic system, which by definition must be nonstationary in the mean. Seismic activity is believed to be a perturbation shifting Old Faithful into a new chaotic state with a different shape to the strange attractor. A simple non-linear dynamic model of geyser behavior is proposed that leads to chaotic behavior and is consistent with the observations of eruption interval data for Old Faithful."

Thirteen years ago, Spiegel participated in a short-term program in which group therapy was given to 86 patients with advanced breast cancer. The goal was simply to make the patients feel better and "face their mortality." The result was that the patients became less anxious, less fearful, and more positive. They even learned to reduce their pain through self-hypnosis. That was the end of the program. Recently, Spiegel, fed up with claims that positive thinking could help control cancer, tracked down the patients who had received psychotherapy earlier.
