Its CCD (Charge-Coupled Device) camera detected a ghostly glow emanating from the vents. Since this mineral-laden water gushing from these cracks in the deep-sea floor exits at 350 -400 C, the simplest explanation of the vent glow is that is is simply thermal radiation from the hot fluid. Indeed, color filters on the camera recorded a spectrum close to that of a 350 C plume. But the deep-sea shrimp camped around the vents have raised second thoughts. The shrimp, only a few inches long, live in the perpetual darkness of the miles-deep vents. They do not need and do not have ordinary eyes. Rather, they sport a mysterious organ on their backs that is connected to their brains by a nerve-fiber bundle much like an optic nerve. This organ is packed with the same light-sensitive pigments found in the eyes of surface creatures. Despite its unusual location on the shrimp, it is an "eye" of sorts. But of what use is it in the Stygian abysses? To find, perhaps, vent glows that betray the presence of chemosynthetic food sources. If this is so, the shrimps' optical organ, which is most sensitive in the blue-green portion of the spectrum, is ...

... mice that construct small pyramids of pebbles to extract moisture from the air, we serendipitously ran across the following: " Australian Native Mice . 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 ."

Dimesized oil globules have been sighted floating near these chimneys. Analysis of chunks broken off the chimneys by research submersibles reveal the presence of petroleum-like hydrocarbons that are less than 5000 years old. It is thought that high-temperature fluids percolating up through the sediments convert buried organic matter into oil very rapidly.

Gold's theory that oil is actually derived from primordial carbon deep in the crust. Gassy water. Some water wells in Texas also produce much methane. This methane is apparently not related to any oil or gas wells in the region. Rather, surmise has it that bacteria deep in the crust are converting buried organic material into methane and other chemical products.

If proven, this would shatter the laws of chemistry and vindicate homeopaths, who say that extremely dilute drugs can have a physical effect." Benveniste's latest scientific paper was published in Comptes Rendus after being rejected by both Nature and Science. Benveniste states that he has corrected the flaws in his original research that evoked passionate responses from the scientific world. However, Benveniste's latest paper prompted one of Nature's reviewers to charge that Benveniste was "throwing out data because they don't fit the conclusion."

Squalls were nothing new to the Marques , one of 39 tall ships participating in a transatlantic race. But as a precaution, Stuart Finlay, the seasoned 42-year-old American captain of the ship, shortened the sails. The Marques was carrying a crew of 28 - half of whom were under 25. At the helm, Philip Sefton, 22, fought the angry waves that now confronted them. "Suddenly a heavy gust of wind pushed the Marques down on its starboard side. At the same instant 'a freakish wave of incredible force and size,' as Sefton later described it, slammed the ship broadside, pushing its masts farther beneath the surging water. A second wave pounded the ship as it went down. The Marques filled with water and sank in less than one minute. Most of the crew were trapped as they slept below deck. Only Sefton and eight shipmates survive." Accounts such as that above are part of sea lore. Waves 50-100 feet high have been frequently reported over the years. Most often, they are encountered in rough seas, but some walls of water have smashed ships in relatively calm waters.

Using a new method for quantitative enumeration, we have found up to 2.5 x 108 virus particles per millilitre in natural waters. These concentrations indicate that virus infection may be an important factor in the ecological control of planktonic microorganisms, and that viruses might mediate genetic exchange among bacteria in natural aquatic environments."

This level of virus density in natural water is about 10 million times that formerly estimated. Besides reducing your thirst, what are the implications of this discovery? First, it suggests that bacteria in natural waters are probably kept in check by viruses as well as protozoans. So far, this sounds good. Second, since viruses can ferry genetic material between organisms via transduction (i .e ., host DNA is carried to the next host).

Geologists custom-arily explain drumlins as debris piled up and sculpted by the ice sheets them-selves, despite the fact they look like they might have been shaped by flowing water. As we all know, the word "flood" is an anathema in geology, probably because a provable episode of extensive flooding would lend credence to the Biblical Flood! (Actually, many cultures around the world have similar flood legends.) Canadian geologist J. Shaw is now trying to break out of this philosophical prison. "According to Shaw, heat from the Earth formed huge lakes of meltwater that remained trapped beneath the North American ice sheet. As the sheet began to retreat near the end of the glacial age, the water broke through and flowed in torrents down to the Gulf of Mexico and Atlantic Ocean. While flowing under the ice cap, water would have surged in vast, turbulent sheets that sculpted and scoured drumlins. Each flood lasted until the weight of the ice cap once again shut off the outlet of the covered lake, Shaw says." Shaw goes on to estimate that one large drumlin field in Saskatchewan was created when ...

They had learned that piles of porous rocks could, in desert climes, capture and condense surprisingly large quantities of water. Take, for example, the 13 pyramids of loose limestone rocks that the Greeks constructed some 2500 years ago at Theodosia in the Crimea: "The pyramids averaged nearly 40 feet high and were placed on hills around the city. As wind moved air through the heaps of stone, the day's cycle of rising and falling temperatures caused moisture to condense, run down, and feed a network of clay pipes. "One archaeologist calculated a water flow of 14,400 gallons per pyramid per day, based on the size of the clay pipes leading from each device." Weren't the ancient Greeks clever?

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.

The quotation above once again evokes the concept of "crevicular structure" in the crust. The crevicular world is that immense, unappreciated maze of underground space created by cracks in the rocks, solution channels, permeable gravels, and so on. In the article reviewed here, a crevicular realm has been discovered underneath river beds. But this is just a special case of a subterranean world found many places beneath the surface -- even under the continental shelves. The surface waters we see are just (to use an aquatic metaphor) the tip of the iceberg! Sub-river life lives far under the beds of the great Alaskan rivers and even small desert streams in Arizona.

If you wish, you can accelerate the substance's demise by touching a match to it; it is packed with potential energy. The substance is methane hydrate, and it is found in prodigious quantities in oceanic sediments. Each cubic centimeter of methane hydrate contains about 160 cubic centimeters of methane at standard conditions; it is a concentrated source of natural gas. In fact, methane hydrate deposits in the world's oceans hold twice as much carbon as all the coal, oil, and gas reserves on land! But methane hydrate may be much more than a future fuel source; it may have been humanity's savior in eons gone by; it may be our future nemesis. You see, methane hydrate is very unstable; changes of temperature or pressure on a global basis can trigger the release of immense volumes of this greenhouse gas from oceanic deposits. For example, when the Ice Ages lowered ocean levels by locking up water in the advancing ice caps, pressures on ocean-bottom methane hydrate lessened and, according to some speculators, released enough gas so that the increased greenhouse heating turned back the Ice Ages.

What, then, could be the purpose of the hammer head? No one really knows, but three suggestions are as follows: The head acts as a hydrofoil and gives the heavier-than-water, swimbladderless shark better swimming control. Grooves on the hammer head channel water toward the nostrils, providing "stereoscopic sniffing." The head is a platform for electromagnetic sensors that help locate prey. Stingrays are a favorite food of the hammerhead, and the shark may de-tect them electromagnetically, as surmised by the author of this article in the following encounters: "I have observed great hammerheads swimming close to the bottom, swinging their heads in wide arcs (a motion common, in a lesser degree, to all large sharks) as if using the increased electroreceptive area of their hammer like the sensor plate of a metal detector.

To make bark paper, one first takes the inner layer of bark, or bast, from a tree. This material is then thinned, widened, and made flexible by soaking it in water and beating it. The final product retains much of the bark's structure with its interconnecting fibers. Ordinary paper today is also made of wood fibers, but the original fiber interconnections are destroyed in the pulping process. The manufacture of bark paper requires characteristic grooved beaters, specimens of which have been found in both Mesoamerica and Southeast Asia. Were bark paper and the tools required to make it invented independently on both sides of the Pacific, or were they transported across the Pacific by early navigators? If the latter, the flow was probably from Asia to America because the paper-making tools first appeared in Southeast Asia 4-5000 years ago and in Mesoamerica only 2500 years ago. Even so, trans-Pacific voyages 2500 years ago are definitely not part of acceptable archeology. Anthropologist P.
