... divers cannot see beyond a few feet. Measured in millimeters, the marine snowflakes are much larger than the average interplanetary dust particles (but of course interplanetary dust itself is also a constituent of marine snow). The bigger marine snowflakes -- over 0.5 mm -- are a major food source for deep-sea denizens waiting below for this manna from the watery heaven. The reason for mentioning marine snow in Science Frontiers is that biologists like Alldredge are really pio-neering new territory, where new anomalies must surely dwell.

Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Microbes Threaten Radiocarbon Dating In the 1980s, skeptics had a lot of fun debunking the Shroud of Turin, the supposed burial cloth wrapped around Christ. Their glee was unbounded when radiocarbon dating "proved" that the shroud could not be older than 700 years. The skeptics may have been too quick to celebrate, because the samples that were sent to the radiocarbon lab may not have been wholly cloth. The reality of our biosphere is that virtually everything is permeated with microbes and their products. S.J . Mattingly and L.A . Garza-Valdes, of the University of Texas at San Antonio, have been studying "biogenic varnishes" for years. These plastic-like coatings are produced by bacteria and fungi. Sure enough, microscopic examination of a few linen fibers from the Shroud of Turin show that they, too, are coated with such varnishes. These biogenic varnishes may introduce carbon that has been recently fixed from the atmosphere and thus make the sample's age appear younger than it really is. (Travis, John; "Microbes Muddle Shroud of Turin's Age," Science News, 147:346, 1995.) Comment. More than the Shroud is at stake here. Bacteria contaminate just about everything, including wood and bone from archeological sites. Bacteria may, therefore, "rejuvenate" samples sent in for radiocarbon dating. The importance of this phenomenon is still unclear. Cross reference. Radiocarbon-dated samples may also appear erroneously "aged" by ...

... of the University of Heidelberg have looked at the proteins in the blood serum of megabats and primates and found enough in common to suggest a close taxonomic relationship between the two groups. (Biological Journal of the Linnean Society, 51:359)" An explanation might be that the similarities between the microbats and megabats represent adaptations to similar environmental niches rather than a common ancestry.

Along its course, 27 major towns dump 902 million liters of sewage into it each day. Added to this are all those human bodies consigned to this holy river, called the Ganga by the Indians. Despite this heavy burden of pollutants, the Ganges has for millennia been regarded as incorruptible. How can this be? Several foreigners have recorded the effects of this river's "magical" cleansing properties: Ganges water does not putrefy, even after long periods of storage. River water begins to putrefy when lack of oxygen promotes the growth of anaerobic bacteria, which produce the tell-tale smell of stale water. British physician, C.E . Nelson, observed that Ganga water taken from the Hooghly -- one of its dirtiest mouths -- by ships returning to England remained fresh throughout the voyage. In 1896, the British physician E. Hanbury Hankin reported in the French journal Annales de l'Institut Pasteur that cholera microbes died within three hours in Ganga water, but continued to thrive in distilled water even after 48 hours. A French scientist, Monsieur Herelle, was amazed to find "that only a few feet below the bodies of persons floating in the Ganga who had died of dysentery and cholera, where one would expect millions of germs, there were no germs at all. More recently, D.S . Bhargava, an Indian ...

... proceeds "blindly"; that is, mutations are random and unrelated to the biological needs for survival. This assumption is enshrined in R. Dawkins' book The Blind Watchmaker . Catchy though this title is, it looks more and more like the Watchmaker sees something. For over a decade, experiments have hinted that those mutations that are helpful to an organism's survival occur more often than those that are not "adaptively useful." This controversial phenomenon is termed "adaptive mutation." (SF#64 and SF#96*) A recent issue of Science presents two more papers that seem to confer the gift of sight on the old Watchmaker. Biochemist J.A . Shapiro, in a commentary accompanying the two Science papers, highlights a significant feature of adaptive mutation in bacteria: The genetic changes involved are multicellular. In other words, DNA rearrangements in one cell are actually transferred to other cells. But most profound of all for the whole science of biology is his sentence: "The discovery that cells use biochemical systems to change their DNA in response to physiological inputs moves mutation beyond the realm of 'blind' stochastic events and provides a mechanistic basis for understanding how biological requirements can feed back onto genome structure." (Shapiro, James A.; "Adaptive Mutation: Who's Really in the Garden?" Science, 268:373, 1995.) Comment. Random mutation has been a linchpin of Neo-Darwinism because it is "scientific"; that is, non-supernatural. We see in adaptive mutation that other scientific mechanisms ...

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.

The light was strongest at the red end of the spectrum, but fell below detectable levels in the ultraviolet. Significant variations were observed between individuals in both photon rate and spectral profile. The photon rate also varied significantly with time for a single individual." It is important to recognize that, although the flux of photons emitted by individual cells is very low, it greatly exceeded the flux of blackbody radiation at 37 C (about 10-9 photon/s /cm2).

Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Preadaptive Evolution "Preadaptive evolution" is a remarkable concept. Basically, it asserts that in some -- possibly many -- mutations, a useful response to an evolutionary challenge is "naturally" accompanied by useful responses to challenges that have not yet been posed to the life form in question. This prescience verges on the miraculous to the uninitiated, but mainstream biologists seem content to write the phenomenon off as merely good fortune -- like hitting two jackpots in a row on the same slot machine. A good example of preadaptation occurs when bacteria are cultured in the presence of an antibiotic. Within a few weeks, they have evolved a resistance to that particular antibiotic. This well-known phenomenon is easily explained by evolution. However, often the newly evolved (or "adapted") bacteria are also resistant to several other antibiotics that work by different mechanisms. All of the multiple gene changes needed for the several different defense mechanisms are controlled by a single site on the same chromosome. (Levy, Stuart B.; The Antibiotic Paradox , New York, 1992, p. 99. Cr. A. Mebane.) Comments. How can bacteria prepare defenses against antibiotics they have not been exposed to?

... is the discovery that the geological age of today's oil is quite different from that recovered 10 years ago. What's going on under the Gulf of Mexico? It is difficult to avoid the conclusion that the oil reservoir at Eugene Island is rapidly refilling itself from "some continuous source miles below the earth's surface." In support of this surmise, analysis of seismic records revealed a deep fault which "was gushing oil like a garden hose." The deep-seated oil source at Eugene Island strongly supports T. Gold's theory about The Deep Hot Biosphere . Gold holds: "that oil is actually a renewable, primordial syrup continually manufactured by the earth under ultrahot conditions and tremendous pressures. As this substance migrates toward the surface, it is attacked by bacteria, making it appear to have an organic origin dating back to the dinosaurs." The apparent deep-seated oil source at Eugene Island and Gold's ideas make petroleum engineers wonder about a similar situation at the seemingly inexhaustible oil fields of the Middle East. "The Middle East has more than doubled its reserves in the past 20 years, despite half a century of intense exploitation and relatively few new discoveries. It would take a pretty big pile of dead dinosaurs and prehistoric plants to account for the estimated 660 billion barrels of oil in the region, notes Norman Hyne, a professor at the University of Tulsa in Oklahoma.

Only when we get the flu or infected finger do these entities impinge upon our consciousness. Below we will learn that there are many more of them than you think. Do viruses control the oceans? You may avoid the beaches after you learn that one teaspoon of seawater typically contains 10-100 million viruses and onetenth that many bacteria. Obviously, most are harmless to humans. However, the viruses do infect the bacteria and phytoplankton, destroying them, and thereby releasing their nutrients. By doing this, they keep the oceans' biological engines running. Further, the viruses act as genetic engineers as they transfer DNA from one individual to another. The oceans may be viewed as vast test tubes in which biodiversity is maintained by teeming, invasive viruses. (Suttle, Curtis A.; "Do Viruses Control the Oceans?"

Of course you know about microbes. Well, nanobes are also life forms but so much smaller than microbes that they deserve the prefix "nano" (for 10-9 ) rather than "micro" (for 10-6 ). The smallest recognized bacteria, Myco plasma , lack cell walls and fall in the size range 150-200 nanometers. Nanobes are much smaller: 20-150 nanometers. But are nanobes really alive? A drill core recently extracted from a stratum of sandstone 3 kilometers deep off the coast of Western Australia was found to be infected with miniscule filamentous structures. P. Uwins and her colleagues at the University of Queensland believe these structures (" nanobes") are alive. They appear to grow and have cell walls. But skeptics assert that some lifeless chemical structures also grow. Others suspect contamination of the sample as it was raised to the surface and handled.
