Billions of stars are nothing to them. The megaparsec (3 ,528,000 light years) is but a hop, skip, and jump. A pressing question for these cosmologists searching for the really big picture is whether there is any order in the distribution of galaxies, galactic clusters, and superclusters. The scale of organization of the universe is of critical importance because it is a measure of state of the cosmos when hydrogen atoms first condensed from the seething sea of ions following the Big Bang. The prevailing expectation has been that galactic clusters and superclusters should be distributed at random; that is, no order prevails at that scale. Recent redshift measurements, however, hint more and more forcefully that the huge superclusters of galaxies are almost as neatly arranged as the atoms in a crystal. A recent paper in Nature by J. Einasto et al puts a number on the spacing of the superclusters: "Here, using a new compilation of available data on galaxy clusters, we present evidence for a quasi-regular three-dimensional network of rich superclusters and voids, with the regions of high density separated by "120 Mpc [megaparsecs]. If this reflects the distribution of all matter (luminous and dark), then there must exist some hitherto unknown process that produces regular structure on large scales."

"At about 2240 UTC, the observers saw a strange effect in the sea stretching for approximately 100 m from the parallel body. It was a soft white light, almost strobe-like in character that pulsed irregularly. The light was bright enough to illuminate the wheelhouse deckhead and seemed to emanate from below the water, almost as if something was shining a spotlight upwards, shimmering and twirling: psychedelic projections of the 1960s were brought to mind. Curiously, the wash from the bow was not illuminated and appeared normal, likewise the wake." The phenomenon lasted for 6 or 7 minutes, faded, and then reappeared briefly. The night was clear and the visibility excellent. (Griffiths, P.J .; "Bioluminescence," Marine Observer, 66:183, 1996.) Comment.

The geomagnetic field, the sun, the stars, prominent landmarks, and even odors help guide them across the continents and open seas. But birds are considered highly evolved animals so their sophisticated navigational techniques are not especially surprising. Monarch butterflies, however, are mere insects, with tiny brains (navigation-data processors) and not much in the way of the environment sensors and internal clocks required for long-distance migration. Yet, some of these colorful insects manage to flutter up to 4,000 kilometers from the eastern U.S . and Canada to their wintering grounds in Mexico. How do they do this? S.M . Perez et al have now shown that monarch butterflies are equipped with a sun compass; that is, they chart their courses by noting the sun's changing azimuth. This feat requires not only the measurement of solar azimuth but also reference to an internal clock. Humans cannot do this without artificial instruments. Furthermore, even on cloudy days, migrating monarchs fly in the proper direction (generally south-southwest). Apparently, they also have evolved a backup navigation system, perhaps a geomagnetic compass. (Perez, Sandra M., et al' "A Sun Compass in Monarch Butterflies," Nature, 387:29, 1997.) Comment ...

... sedimentary rocks up to 3.5 billion years old in Africa and Australia. These bitumen nodules were formed when natural hydrocarbons were irradiated by radioactive isotopes that coexisted in the ancient rocks. Futhermore, these African and Australian rock formations were never severely deformed or subjected to high temperatures. The possibility exists, therefore, that some of the earth's oldest rocks may contain substantial oil reserves. So far, no one has seriously looked for oil in Precambrian rocks because of the two preconceptions noted above. (Palmer, Douglas; "Any Old Oil?" New Scientist, p.22, March 14, 1998.) Comments. Large quantities of oil and bitumen 3.5 billion years old have profound implications. Far from being lifeless, the most ancient of our planet's seas may have been thick soups of bacteria and other simple life forms. So much terrestrial life so soon after the formation of the earth could imply that there was an extraterrestrial inoculation of biotic material that gave terrestrial life a jump start -- assuming that this ancient oil and bitumen are truly biogenic!

Sure, there are also a few creatures that derive their energy by oxidizing the sulfides dissolved in the 400 water gushing forth from deep-sea vents. We will call them "geochemical creatures" to separate them from the "photosynthetic creatures" we are more familiar with. But, in principle at least, there could also be "Carnot creatures", whose metabolisms depend upon temperature differences like almost all human-built engines. Some bizarre animal, such as a meter-long tube worm, could plant one end on a hot rock surface and dangle the other in cold seawater to reject waste heat from its Carnot engine. Since thermodynamic-cycle efficiencies can approach 60% compared with only 10% for photosynthesis, evolution would have been remiss if it had not tried to evolve "Carnot creatures." For, as D. Jones comments below, Carnot creatures would be adaptable to many more habitats in the universe than photosynthetic creatures, which must have a sun with a very specific electromagnetic spectrum. "Many worlds, from distant 'brown dwarf' stars to the satellites of giant planets, may have internal heating but no effective 'Sun'.

The ecosystems clustered around the deep-sea vents and the bacteria found in deep aquifers demonstrate that the sun is not essential to life -- chemical energy does just fine. In fact, the domain of chemosynthetic life has now been extended to a Romanian cave that has apparently been almost completely sealed off from surface influences for 5.5 million years. Air does leak in through tiny cracks, and water partially fills the cave. What is most remarkable in this sunless, sealed ecosystem is its biodiversity: 48 animal species, including 33 brand-new species. The roster includes isopods, a millipede, a centipede, a water scorpion, and a leech. Of course, bacteria and fungi thrive there, too. In contrast to unsealed caves, where insects, bats, and other sources of food filter in from the surface, life in the Romanian cave seems to derive entirely from hydrogen sulfide present in the cave's rocks. This compound is consumed by microorganisms, which are then grazed by cave occupants higher up the food chain. A NASA scientist has called Movile cave a "Mars analog site." And indeed it might be, for Mars has plenty of rocks and subsurface water. (Skinrud, E.; "Romanian Cave Contains Novel Ecosystem," Science News, 149: 405, ...

Wave-height measurements at the Seven Stone Light Vessel, anchored in the northeastern Atlantic, show that wave heights have increased 2.4 centimeters/year during the period 1960-1985. This is not a trivial amount. At this rate, waves a century from now would be 2.4 meters (about 8 feet) higher. Many existing coastal structures will be smashed to bits. All this is over and above any effects from rising sea levels. The records from the Seven Stone Light Vessel are corroborated by an analysis of more then 20,000 wave charts of the North Atlantic drawn between 1960 and 1988. It therefore seems clear that something unusual is going on in the North Atlantic. One would suspect increased winds, but velocities measured at Seven Stone have remained constant while wave heights rose. It is concluded that the bigger waves are not generated by local winds; rather, they are swells that have been created thousands of miles away. The cause of these larger swells now affecting the entire North Atlantic is not known. The authors of this paper are forced to conclude with: "It should be noted that so far it has not been possible to attribute the observed change to either an anthropogenic cause or to natural climate variability on decadal time scales."

Much more devastating to the killerwhale image is an article in Natural History describing the vicious attack of a pack of killer whales on a pod of much larger sperm whales 70 miles off the California coast.

What was the purpose behind this strange geoglyph? One of the most engimatic giant ground drawings (or "geoglyphs") in South America is seen best from several miles out at sea. Etched into a sloping hill at Pisco Bay on the Peruvian coast, this strange figure looks vaguely like a candlestick; thus, its name "The Candelabra of the Andes." The Candelabra is 595 feet long and can be seen from as far as 12 miles out to sea. Pottery found near the figure has been carbondated at 200 BC and is assignable to the Paracas Culture. Separated by 130 miles from the Nazca Plain, with its famed giant figures, the Candelabra apparently is not the work of the Nazca people. It is puzzling why that such a figure would be placed where it could be seen best by sailors. As with Costa Rica's stone spheres, the Candelabra's makers, purpose, and symbology are in doubt. The Pisco geoglyph really doesn't match the motifs in our books on South American archeology. Some archeologists say it is only a trident, but who ever saw a trident like this? F.

"I think that flying fish are just taken for granted but perhaps if we looked at them more closely, then we may see some really weird and wondeful colours, especially in island areas. What does baffle me, is why, when the wings are only extended during flight, they should be of differing colours.

Perhaps a more profound question is: Why do sea-shells need to be pretty in the first place? After all, most (but not all) of the shell owners do not have eyes with which to appreciate their handiwork! However, mathematicians and computer modellers do have eyes. They have also had a lot of fun and some success in devising algorithms (mathematical methods) for the generation of seashell markings. In fact, our title above is also the title of a new book by H. Meinhardt, which suggests how a suite of simple biochemical processes can create those shells coveted by collectors. Meinhardt has devised equations that describe chemical factors that turn pigment-generating cells on and off. In its simplest form, a mathematically modelled seashell is a two-dimensional sheet that grows along only one edge. Cells on this edge may or may not secrete pigment depending upon chemical "influences." B. Hayes describes how this sort of model operates: The triangular pattern on Cymbiola innexa suggests the presence of a "global control element" that turns the pigment-secreting cells on and off in the correct order -- something like a computer-controlled loom!

Old Kingdom craftsmen laboriously cut this hard, black, glassy rock into royal sarcophagi and pavements for the mortuary temples at Giza just outside Cairo. To transport the heavy blocks of basalt from the quarry to Giza, the Egyptians built a quay on Lake Moeris, which then had an elevation of 66 feet above sea level and was located 7 ½ miles southeast of the quarry. (The Lake is now much smaller and 148 feet below sea level, indicating a large climate change.) Then, when the Nile flooded and its waters reached a gap in the hills separating the Lake and the Nile, the Egyptians were able to float the blocks of basalt over to the Nile and down to Cairo. Good thinking! But how did they transport the heavy blocks 7 ½ miles from quarry to quay? The answer: What was apparently the first paved road on the planet. This 4,600-year-old engineering feat averaged 6 ½ feet wide and was paved with thousands of slabs of sandstone and limestone, with some logs of petrified wood thrown in. Since the slabs show no grooves, it is thought that the stone-laden sleds moved on rollers.

"Contemporary neuroscience suggests the existence of fundamental algorithms by which all sensory transduction is translated into an intrinsic, brain-specific code. Direct stimulation of these codes within the human temporal or limbic cortices by applied electromagnetic patterns may require energy levels which are within the range of both geomagnetic activity and contemporary communication networks.

These are the rays that penetrate to the greatest depths in the sea. This adaptation to blue light means that deepsea fish have evolved visual pigments different from those of surface fish and land animals. Visual pigments are complex chemical compounds, and one must suppose that many, many random mutations took place before deepsea fish were able to manufacture visual pigments different from their relatives living near the surface. (Or did deepsea fish come first?) But there is more to this story. Many dwellers in the black abysses generate their own light. They sport bioluminescent organs so they can be seen by others of their own species and, in addition, illuminate prey for easier capture. In another remarkable example of evolutionary convergence, these bioluminescent organs emit light spectrally matching the eye sensitivity of deepsea fish! So far, though, this story is not any more amazing that many others woven into evolution's fabric. But suppose that a deviant species of deepsea fish upset this cosy status quo by evolving visual pigment and bioluminescent organs operating in a part of the electromagnetic spectrum that other deepsea fish could not perceive.

These slowmoving internal waves take 5 days to reach Puerto Rico, where they emerge as coastal seiches. Similar internal waves created by tidal currents at the edges of the continental shelves and deepwater sills may explain the mysterious coastal seiches recorded in the Anadaman and Sulu Seas.

But the bits of drillers have demonstrated that life prevails as far down as we can pierce the planet's integument. Now, K.G . Stetter et al: ". .. report the discovery of high concentrations of hyperthermophiles [viz., bacteria] in the production fluids from four oil reservoirs about 3,000 metres below the bed of the North Sea and below the permafrost surface of the North Slope of Alaska. Enrichment cultures of sulphidogens grew at 85 C and 102 C, which are similar to in reservoir temperatures." Stetter et al favor the theory that these hyperthermophiles were injected into the reservoirs through: (1 ) drilling and secondary-recovery operations; and/ or (2 ) natural penetration via faults and seeps. They pointedly distance themselves from the idea, championed by T. Gold, that subterranean bacteria are actually permanent ancient residents of a deep subterranean biosphere. (Stetter, K.O ., et al; "Hyperthermophilic Archaea Are Thriving in Deep North Sea and Alaskan Oil Reservoirs," Nature, 365:743, 1993.) On the other hand, in their comments on the above paper, J. Parkes and J. Maxwell do ...
