When a recent photo of the "Face" taken by the Mars Global Surveyor (MGS) was published far and wide in the science press, we thought the matter had finally been settled. The photo showed a strange hill obviously sculpted by natural forces. No question about it; there was not a soupcon of artificiality. But it now seems that if you look at the "Face" at other lighting angles and process the same data in different ways, the "Face" reappears looking more artificial than ever. T. Van Flandern elaborates: The MGS spacecraft took a high resolution photo of the "Face on Mars" in April 1998. That image suffered from four handicaps: a low viewing angle; a low sun angle from the direction of under the "chin"; an almost complete lack of contrast; and enough cloudiness to scatter most of the light and eliminate shadows. To add to these difficult circumstances, JPL-MIPL [Jet Propulsion Laboratory-Mission Image Processing Laboratory] personnel, apparently judging that the controversy over artificiality would not be ended when the actual photo was released, processed the image through two filters having the effect of flattening and suppressing image details. This step is documented at a JPL web site. Here we ...

Scuba divers could not resist the challenge. As they explored the murky depths, they chanced upon deposits of spongy, red slime. When analyzed, the slime was found to contain the first naturally produced nanocrystals. Nano-crystals, like those described above under BIOLOGY, had previously been grown only in the lab. Also like the artificial nanocrystals, those in the red slime did not aggregate randomly; they "rotate into structural accord with the adjacent particles." Whence the slime's 2-3 nanometer clumps of iron oxyhydroxide? Iron-oxidizing bacteria excreted them! (Anonymous; "Strange Crystal Growth Found in Mine," Science News, 158:207, 2000.) Question.

In the five years that have transpired, Galileo has radioed back voluminous data about Jupiter itself and its four large Calilean satellites. These natural satellites have turned out to be a disparate bunch. Three have iron cores, but Callisto breaks the mold with an unusual core of mixed ice and rock. Europa probably possesses an ocean, and Callisto might also. Only one of Jupiter's large satellites, Ganymede, boasts a magnetic field. In fact, Ganymede is apparently the only satellite in the solar system to display an intrinsic, dipole magnetic field like the earth's . Although Ganymere's magnetic field is like that produced by a permanent bar magnet, its core is much too hot for permanent magnetism. Again like the earth, Ganymede's field is theorized to be generated by the convection of electrically conducting liquid in its core -- a dynamo of sorts. All well and good, but Ganymede is so small that it should have cooled off billions of years ago thereby freezing its metallic core. So then, whence its magnetic field? One way out of this box it to suppose that about a billion years ago Ganymede was circling Jupiter in an orbit that took it much closer to this ponderous planet. Then, Jupiter's powerful ...

In other words, the cutting of the computer's interconnections did not result in gibberish, rather memories that were previously stored flashed through its data processors. Something similar seems to happen with nonfictional computers. When a type of computer program termed an "artificial neural network" is "killed" by cutting links between its units, it in effect approaches a state which "might" be something like biological "death." S.L . Thaler, a physicist at McDonnell Douglas, has been systematically chopping up artificial neural networks. He has found that when between 10% and 60% of the network connections have been severed, the program generates primarily nonsense. But, as the 90% (near-death!) level is approached, the network's outout is composed more and more of previously learned information, like HAL's learned song!

"A large number of anomalous landforms on Mars can be attributed to glaciation, including the action of ice and meltwater. Glacial landscapes are concentrated south of lat -33 and in the Northern Plains suggesting vast Austral and Boreal ice sheets. Crater densities on the glaciated terrains indicate that the final glacial epoch occurred late in Martian history. Thus, Mars may have had a relatively warm, moist climate and dense atmosphere much later than previously believed." (Kargel, Jeffrey S., and Strom, Robert G.; "Ancient Glaciation on Mars," Geology, 20:3 , 1992.)

Instead of ending with an exclamation point, a question mark would have been more appropriate. The Perseus Flasher, a recurring flash of light in Perseus described in SF#39 and #49, is a topic upon which astronomers also wish to "close the book." So, we must ask ourselves how accurate the above title is. Photographic records of the Perseus Flasher site show no flashes at all in 3,288 hours of monitoring. In fact, a Harvard plate, which was being exposed at the same time that a 0-magnitude flash was reported by naked-eye observers, revealed nothing! The passages of some artificial satellites through the Perseus site have been correlated with naked-eye-observed flashes, suggesting that the flashes are only sun glints. One meteor observer, N. McLeod, claims that there is a background level of flashes from other parts of the sky which can also be attributed to satellite glints. The Sky and Telescope item concludes: "So the mystery is solved!" (Anonymous; "The Perseus Flasher: Mystery Solved!" Sky and Telescope, 73:604, 1987.) Comment.

... bending the velocity vectors of marine algae From the referenced paper's abstract: "A consciousness experiment in which the Doppler shift of He/Ne laser light was used to describe changes in the velocity and vector of a marine alga, Dunaliella, was reported by Pleass and Dey in 1985. Because the subject of the consciousness experiment is living, we expect strings of baseline velocity and vector data which are, at some level, inextricably time-variant. This complicates the statistical procedures which must be used to analyze the data. "This paper examines the variation in baseline data strings, and describes two alternative statistical procedures which have been used to determine the probability of consciousness effects. Two levels of control are applied, allowing global comparison of frequency distributions of experimental scores with similar distributions derived artificially from baseline data. In both cases the null hypothesis is that there is no psi effect. The data quite strongly suggest the rejection of the null hypothesis, although the distributions of run scores contain several values beyond 3 sigma and are nonnormal. This limits the definition of probabilities." (Pleass, C.M ., and Dey, N.

B consists of a parallel row of stones. D is made up of regularly spaced piles of stones and extends over 1 miles, cutting diagonally across ancient beach lines. Richards also employed a satellite image of the area to locate other "regular" features, such as a triangle, a pentagon, and a sharp, right-angle corner with mile-long sides. Inspecting these regularities from a small boat, Richards found no obvious structures of any kind. Rather, the patterns were caused by sea grass and white sand. Even so, these superficial patterns may reflect the presence of artificial structures under the sediments. Certainly, if these regularities were observed in a photo taken over land, archeologists would rush to dig away the overburden.

Moore, the author of this article and a creationist, suggests that creationists no longer use the Paluxy tracks as evidence that humans and dinosaurs once coexisted. But he adds that several mysteries still exist, two of which are: (1 ) Why is erosion improving the quality of the tracks instead of the reverse? (2 ) Why aren't those tracks exposed earlier also acquiring the stain marks? Moore also points out that the reddish stains could have easily been added artificially!!

In May 1977, ORION placed a 500,000 candlepower arc light in Lenoir, 22 miles east of Brown Mountain. Simultaneously, a group of observers gathered on an overlook on Route 181, 3.5 miles west of Brown Mountain, a favorite spot for watching for the Brown Mountain lights. Brown Mountain itself was inter-posed between the arc light and obser-vers. When the arc light was switched on, the observers saw an orange-red orb hovering several degrees above the crest of Brown Mountain. Conclusion: the majority of the so-called Brown Mountain lights, particularly those seen above the crest, are refractions of artificial lights. The real Brown Mountain lights, the mysterious ones, are those that flit through the trees well below the crest. These lights are extremely rare. Typically, they commence as a brilliant blue-white or yellow light, which tapers off to dull red before disappearing, all in 2-10 seconds. Horizontal motion is often only a degree or so, although some older reports have the lights wandering greater distances at speeds faster than a human could manage in the difficult terrain. In an experiment to determine whether the "true" Brown Mountain lights might be seismic in origin, ORION detonated small charges on Brown Mountain in July 1981. No artificially stimulated lights were recorded. (Frizzell, Michael A.; "Investigating the Brown Mountain Lights," INFO Journal, 9 ...

... , 1984.) Comment. Two comments here: First, the word "spontaneous" is customarily employed when describing how atoms unite to form molecules and molecules combine into polymers, which then gather into microspheres. The word "spontaneous" seems to imply chance is operating rather than design. Actually, atoms and even subatomic particles must have innate properties which force them to combine into larger structures the way they do. Philosophically, one can ask whether the lowliest subatomic particles are "coded" to combine into molecules, microspheres, and living creatures. In other words, the design of life could be inherent in quarks. Second, if nonliving microspheres possess some of the properties of neurons, it is possible that natural, nonliving minds can form spontaneously -- a sort of "natural" artificial intelligence! Mind, then, could preced life, which is manifestly more complex than computers. The science-fiction possibilities are endless here. From Science Frontiers #35, SEP-OCT 1984 . 1984-2000 William R.

Hals first observed long-delayed radio echoes in 1927. During the following half-century, scientists have been studying this perplexing problem, but it has been the amateurs who have accumulated the bulk of the data. Over 100 reports exist where echoes of radio transmissions were received seconds later at the original transmitting station. Since light travels 186,000 miles per second, any simple radio-wave reflector would have to be well beyond the moon's orbit. A wide variety of natural phenomena (interplanetary matter) and even artificial devices (alien space probes) have been postulated to explain the long delays. Muldrew's article is first of all an excellent summary of the long and fascinating history of this effect. His bibliography is extensive and apparently nearly complete. Muldrew next examines the various ionospheric mechanisms that might cause long delays. The ionosphere is a complex structure with ducts in which radio signals can get trapped. Delays of a second or so might be due to such trapping but the longer delays require some other explanation. Muldrew favors a rather complex interaction between signals from separate transmitters that (theoretically at least) can create a long-lived electrostatic wave that travels in the ionosphere -- a sort of natural memory device. The coded signals could then be read out much later when the proper natural conditions developed. Delays of up to 40 seconds might be possible with this "ionospheric memory ...

In nature it sometimes occurs in long prisms of hexagonal cross section. In fact, ancient Micronesians quarried multiton basalt prisms to build their fantastic megalithic complex of 92 artificial islets at Nan Madol. (SF#45) The inhabitants of ancient Mesopotamia had no basalt quarries at hand. Indeed, building stone of any kind was exceedingly scarce. What the Mesopotamians of the second century B.C . did have in abundance was alluvial silt. From this unpromising material they were able to make their pottery, writing tablets, and art objects. However, for grinding grain and engineering structures they needed something harder and stronger. Their innovative solution was: artificial basalt made from silt. They simply melted the silt and let it cool slowly. Sounds simple, but three remarkable intellectual and technical advances were required: The Mesopotamians first had to recognize that silt could be melted. This could not have been obvious in 1000 BC. Next, they had to develop hightemperature (1 ,200 C) smelters that were much larger than those they used for metallurgical purposes. Finally, they had to discover that slow cooling was needed for the growth of large crystals in the cooling melt. (Of course, they had no microscopes to see the crystals. So, it had to have been something learned from experience.) That ...

The rectangular stone ziggurat under the sea off the coast of Japan could be the first evidence of a previously unknown Stone Age civilization, say archeologists." Wow! Is this true? This so-called "structure" is 600 feet long and 90 feet high. Said to be about 10,000 years old, it obviously predates the edifices of the ancient Egyptians and Babylonians. The "structure" is now under about 75 feet of ocean near a small island named Yonaguni southwest of Okinawa. During the Ice Ages, it would have been exposed, just like the Bering Land Bridge to the north. Of course, the crucial question is: Is it really artificial? R. Schoch, the Boston University geologist who vouches that the Sphinx is also about 10,000 years old (SF#79), described the "structure" as a series of huge steps about 1 meter high. Schoch is impressed by the regularity of the steps, but does not discount a natural origin. A photo taken by divers does reveal a remarkably regular, stepped surface, but nature can be very methodical on occasion.

The group discovered that they could make ordinary sand musical by repeated grinding, polishing, and removal of fines. Given sufficient processing, ordinary sand that is merely "noisy" when shaken can be made to "sing." Singing sand has a unique infrared signature: a broad band stretching from 3,700 to 2,800 cm-1 . This is probably due to clusters of water molecules in an amorphous silica layer on the surfaces of the sand grains. Taking a clue from the infrared spectrum, Goldsack et al shook commercially available silica gel in a bottle and heard the familiar tones of singing sand! Their conclusion is that for sand to sing the particles must be coated with naturally (or artificially) created silica gel.

What we now see of the mound was apparently constructed between 900 and 1200 AD. The prevailing dogma has long been that the Indians who built Cahokia worked only with earth, never with stone. Indeed, suitable stone is scarce in the area. On January 24, 1998, while drilling to construct a water drainage system at Monk's Mound, workers hit stone -- at least 32 feet of it -- perhaps a region of cobbles or slabs of rock. This region of stone, of undetermined geometry, is located 40 feet below one of the terrace surfaces, but still well above the base of the mound. The stones could well be an artificial structure of some sort. The discovery challenges the current thinking about the culture that built Cahokia. Only further research will reveal the extent and configuration of the stony region and where the stones may have come from. An editorial in the March 14, 1998, St. Louis Post-Dispatch put the Cahokia discovery in the larger context: New World archeology is in flux.

Once we learn how to measure neutrinos really well, we can start looking for intelligent signals impressed upon them by advanced extraterrestrial civilizations. W. Simmons and colleagues at the University of Hawaii at Manoa point out that neutrinos are much better than electromagnetic waves for galaxy-wide communication. They are not blocked by dust nor are they smeared out by ionized gas. Any civilization clever enough to colonize the entire galaxy would want to send out neutrino signals if only to keep clocks in far-flung star systems synchronized. Simmons et al calculate that a neutrino detector containing a cubic kilometer of seawater could probably detect neutrino signals from artificial sources located within 3,000 light years of earth. A detector that might be able to do this is being installed in the ocean off the Hawaiian Islands. Naturally, it has an acronym: DUMAND = Deep Underwater Muon and Neutrino Detector.
