... M.T . Turvey (University of Connecticut), subjects gave surprisingly accurate estimates of the heights and widths of three different vibrating plates. The plates were concealed behind a screen, but the subjects could remotely control a striker. In further experiments, other subjects could distinguish between the sounds of circular, rectangular, and triangular plates. (Anonymous; "Listen to the Shapes," Science News, 157:171, 2000.) Comment. We all know from experience that small, thin plates produce higher pitched sounds that larger plates. How-ever, the ability to assign accurate dimensions without some training is surprising. The same can be said for the identification of shapes. Who, for ex-ample, has been exposed to vibrating, triangular-shaped plates in ordinary life? Could we be dealing here with another innate talent that, like perfect pitch, seems to have no adaptive value in the evolution of humans? From Science Frontiers #129, MAY-JUNE 2000 . 2000 William R.

... Science Frontiers ONLINE No. 138: NOV-DEC 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects When The Antarctic Was Warm The analyses of ocean-floor sediments deposited recently by melting Antarctic ice sheets reveal that these ice sheets are only about 2,000 years old. The evidence is in the rocky debris scraped up from inland Antarctica and then transported out to sea, where it drops to the sea floor as the ice melts. The grains of rock settle into the ocean sediments which contain biological debris that can be carbon-dated. (Marine life beneath the ice sheets is surprisingly abundant and varied despite the near-freezing temperatures.) A somewhat politically incorrect observation appears in this article. However, the news that the Antarctic Peninsula's ice shelves may have come and gone at least once since the end of the last ice age, about 11,000 years ago, suggests that people may not be fully to blame for the disappearance now underway. Supporting foregoing evidence are studies of Antarctic lake sediments and ancient abandoned penguin rookeries. Everything points to a warmer, more humid Antarctica between 2,500 and 4,000 years ago. (Perkins, S.; "Antarctic Sediments Muddy Climate Debate," Science News, 160: 150, 2001.) Comment. The warmer Antarctic just portrayed might explain those old maps, such as that of Piri Re'is, that seem to depict a relatively ice-free Antartica. The more daring of us might postulate sea commerce between South America, southern ...

... what we know doesn't fit together as well as we thought it did. In particular, the major phylogeny of the animal kingdom as estimated from adult characters doesn't fir very well with that estimated from larvae. Such a discrepancy for different stages has occasionally been reported within families of insects, and it has an apparent resemblance to the discordance occasionally found between phylogenies inferred from morphological and molecular characters. In such cases, the usual conclusion (I ignore data chauvinists) is that we should somehow use all the available information to infer the correct phylogeny. After all, there was just one real phylogeny that occurred in the past, and we want to find it as closely as we can." Comment inserted by the compiler. Van Valen is saying that three evolutionary Trees of Life can be drawn from adult morphology, DNA structure, and larval morphology, and that they may not look the same. Caterpillars may yield a family tree different from that inferred from the butterflies. Which is correct, or are they all correct? Back to the review. Waxing heretical, Williamson points out that an organism may have more than one phylogeny ! Larvae may have ancestries different from the adults. How heretical can one get? But in the ocean, spermatozoa often cannot find an egg of the correct species. They may then fertilize eggs of a distantly related species. In such "wide hybrids," the larvae may resemble one parent and the adults the other. There is much more. The gist of it all is that evolution has been much more than random mutation ...

... too small to be viable. Some experts suggested they were just abiotic crystal-line growths. K.L . Thomas-Keprta, who led the NASA team studying ALH84001, snorted that her group was not so stupid that it would mistake crystals for fossils. ( SF#116 ) Thomas-Keprta et al have now come forward with more evidence that ALH-84001 does indeed contain biogenic material. Those worm-like forms have iron-rich rims containing fine-grained crystals of magnetite, some of which possess a unique morphology and which are essentially identical to the magnetite crystals secreted by magnetotactic bacteria on earth. Their conclusion: In ALH84001, the presence of these elongated prismatic magnetite crystals embedded within the carbonate glo- bules, which clearly formed on Mars, represents strong evidence for life on early Mars.

In it, J. Horgan plays dirges for four phenomena that have received considerable attention in Science Frontiers: (1 ) minicomets; (2 ) cold fusion; (3 ) abiogenic oil; and (4 ) the fifth force. (Apparently Benveniste's "infinite dilution" work has already been in terred.) (Horgan, John; "Death Watch," Scientific American, 262:22, June 1990.) But wait, there is a microwave flicker of life remaining in the minicomets. J.J . Olivero and his colleagues at Penn State have been monitoring the sky with a microwave radiometer in their search for emissions from high-altitude gases. During more than 500 days of observations, they detected 111 sudden bursts of water vapor. Olivero et al suggest that these bursts occur when small, icy comets vaporize at very high altitudes. These minicomets are of the same size (about 100 tons) and frequency (20 per minute over the whole atmosphere) as those predicted by L.A . Frank. Frank's icy comets have been received with about as much warmth as "cold fusion." One reason for the unpopularity of icy comets is that they would have provided sufficient water to fill the ocean basins, thus undermining the accepted view that our oceans derived ...

... #25 and SF#58.) No one questions that radiohalos, whether in biotite or diamonds, arise from the the decay of radioactive inclusions; that is, mineral specks carrying uranium, thorium, or some other radioactive element. But how did these radioactive specks get lodged inside the hollow tubes which themselves are encased within diamonds? The problem is that these specks have much lower melting points than the diamond matrix. Why wasn't the liquid radioactive material dispersed throughout the higher melting point diamond matrix long before the latter crystallized? The same question must be asked about the radiohalos themselves, because the application of heat quickly anneals and disperses them. Complicating the picture still further is the fact that some of the radiohalos arise from the decay of polonium-210, which has a half life of only 138 days. The hollow tubes, the lowmeltingpoint inclusions, and shorthalflife radiohalos combine complicate the explanation of diamond origin(s ) and geological history. (Armitage, Mark; "Internal Radiohalos in a Diamond," Creation Ex Nihilo Technical Journal, 9:93, 1995. This creationist journal is published in Australia. The article is based mainly on: Mendelssohn, M.J . et al; "Internal Radioactive Haloes in Diamonds," Diamond Research , 17:2 , 1979.) Comment.

... Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Man The Scavenger Some 2 million years ago, man's supposed ancestors were meat-eaters. But were they noble hunters with dominion over other life forms? Probably not! The analysis of tool marks on ancient animal bones tells us that human tool marks predominate in regions of the bones where there was little meat, as if ancient humans were dismembering the animals for skins and other products. On the meat-bearing portions of the bones, the tooth marks of non-human carnivores predominate. Where the tool marks overlap the tooth marks of other carnivores, the tool marks are mostly on top of the tooth marks. The gist of the tool-mark analysis is that humans got to the animals second -- after the non-human carnivores. In other words, ancient humans were probably meat scavengers -- opportunists rather than the noble hunters often portrayed. As a matter of fact, one characteristic of a scavenger species is its ability to cover wide areas with little expenditure of energy, like the vultures. Now, human bipedalism is pitifully poor for running down game but great for searching far and wide with minimum physical effort. Tooth-wear studies of ancient human skulls indicate that humans were vegetarians first and meat-eaters second. This situation was suddenly reversed when Homo erectus came along. Then, according to toothwear patterns, there was a shift to a mainly meat diet. This was also the time when ...

... . Deep in the Altai Mountains of southern Siberia. About this date, a wall of water 1,500 feet high surged down the Chuja River valley at 90 miles per hour. How does one deduce such a hydrological cataclysm? A. Rudoy, a geologist at Tomsky State Pedagogical Institute, points to giant gravel bars along the Chuja River valley. These are not the inch-sized ripples we seen on the floors of today's rivers; these are giants measuring tens of yards from crest to crest. Only a catastrophic flood could have piled up these ridges of debris. Rudoy postulates that, during the Ice Ages, a huge ice dam upstream held back a lake 3,000 feet deep, containing 200 cubic miles of water. When the ice dam suddenly ruptured, all life and land downstream was devastated. (Folger, Tim; "The Biggest Flood," Discover, 15:36, January 1994.) Comment. The breaking of Pleistocene ice dams also carved up parts of North America. There was the famous Cincinnati ice dam and, of course, the Spokane Flood that gouged out the Channelled Scablands of the Pacific Northwest, when Lake Missoula catastrophically emptied into the Pacific. See ETM5 in our catalog: Carolina Bays, Mima Mounds. It is described here .

In it, a small seaside town was invaded by birds intent upon homicide. Well, something a little bit like that really happened. The real-life event actually helped Hitchcock plan his movie -- of course, D. Du Maurier's short story with the same title helped even more! Here is what really happened on the California coast: "In 1961, a small seaside town near Santa Cruz was bombarded by hordes of sooty shearwaters. The crazed birds pecked people, smashed into houses and cars, broke windows and staggered around vomiting pieces of anchovy over local lawns." This attack was initially blamed on foggy weather which might have disoriented the shearwaters, which normally stay far out at sea. The latest theory is based on the erratic behavior of the birds. They may have ingested fish that carried a marine neurotoxin called domoic acid. Domoic acid is produced by marine alga that bloom frequently along the California coast.

It is an array of rings, each consisting of three unique cells that are sensitive to touch. Attracted by alluring chemicals secreted by the fungus, the nematodes probe around the rings. In a tenth of a second after they are touched, the fungus rings contract around the interloping nematodes. Again the nematode is doomed as the terrible feeding pegs penetrate its body. Another chemical is then released by the fungus to keep other fungi away from its kill. (Simons, Paul; "The World of the Killer Fungi," New Scientist, 20, March 1, 1984.) Comment.
