About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.


Subscriptions

Science Frontiers ONLINE No. 85: Jan-Feb 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Lures Of Mussels Mussels entrust their larvae to the vagaries of the waters in which they live. How, then, are mussels ever able to colonize rivers, whose currents would always sweep their larvae downstream? A pseudofish with tail, fins, and eye spot displayed by a mussel. "The riverine pioneers ran this roadblock by custom designing their baby mussels to hitchhike on fish. Kneehigh to a pinhead, the larval mussel, or glochidium, is nurtured by the thousands or millions in their mother's gills, and spewed in teeming puffs to the open waters. They cling as benign parasites to passing fish, and take a one- to three-week trip, drawing nutrients through their host's membranes and a free ride to new dwellings. They then drop to the bottom and begin their independent lives, some of which will span a half century or more. "Glochidia that do not hook up with a host fish are doomed. To cover these stakes, the pocketbook mussel and its relatives have evolved a fleshy appendage that flaps in the currents and, to a smallmouth bass, looks like a breakfast minnow. Taking the bait. the duped fish gets doused with glochidia. Another resourceful mussel sends its glochidia out in pulsating little packets resembling worms."

... Jan-Feb 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects An Amusing Assemblage Of Anomalies We don't read much about "waterguns" in the modern scientific literature, but a century ago Nature published many ear-witness accounts of them. These muffled detonations heard near the coasts of almost all the continents are believed by some to be caused by eruptions of methane from the seafloor. The same eruptions probably also account for the myriads of "pockmarks" found in the sediments of shallow seas. Whether this outgassing of methane comes from shallow accumulations of organic matter or from deep within the crust is still debated. Here, geophysics merges with biology. Recently, a group of researchers discovered a large (540 square meters) patch of chemosynthetic mussels in a brine-filled pockmark, at a depth of 650 meters, off the Louisiana coast. The mussels grew in a ring around the concentrated brine. The mussels harbor symbionts which consume the methane still seeping up through the brine from a salt diapir (a massive fingerlike intrusion 500 meters below the brine pool. The origin of some diapirs is not well-understood.) The mussels get the oxygen they require from the ordinary seawater covering the dense brine. Like the biological communities surrounding the "black smokers" and other ocean-floor seeps, the brine-filled pockmark community includes several species of shrimp, crabs, and tube worms. We have here another example of the astounding ability of lifeforms to take advantage of unusual, even bizarre niches. (MacDonald, I. ...

... Science Frontiers ONLINE No. 42: Nov-Dec 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Remarkable Distribution Of Hydrothermal Vent Animals Hydrothermal vents support a bizarre array of large clams, mussels, worms and other curious species. These biological communities are unique in that they are supported not by solar energy but rather the earth's thermal energy. What verges on the anomalous is the appearance in both Atlantic and Pacific Oceans of very similar vent communities, with similar or identical species. How did these continent-separated communities originate ? In the words of the author of the present article, "The cooccurrence of a clam, a mussel, and a vestimentiferan worm at widely separated sites in the Pacific and Atlantic represents either an unusual distribution from a single lineage or, even more remarkably, cases of parallel evolution.

... scientific paradigms. First, though, some statistics about my overall endeavor. This present collection consists of about 1500 items of science news and research originally published in the first 86 issues of Science Frontiers , my bimonthly newsletter. I have organized these items by scientific discipline (archeology, astronomy, etc.), updated them where required, and hopefully woven them into a coherent whole. Some bumpiness and gaps are to be expected because I selected only those tidbits that appealed to me. Complete coverage of all sciences was not a goal. Even so, I believe that most readers will be impressed by the vast panorama of nature laid out here before them. From 40,000-year-old archeological digs in the New World (definitely verboten), to the pseudofish displayed by some mussels, to the geological havoc wreaked by asteroid-raised tsumanis, the variety and richness of natural phenomena are to be seen on every page -- and so are the scientific puzzles they pose. I confess that my newsletter, Science Frontiers , is only as teaser to tempt its readers to partake in a much larger, more comprehensive banquet: the Catalog of Anomalies . This work, now comprising 13 volumes of a projected 30, represents my entire file of some 40,000 items gleaned from a survey of about 14,000 volumes of science journals and magazines from 1820 to date. This massive hoard of scientific engimas, paradoxes, and esoterica was assembled bit by bit from 363 volumes of Nature, 260 volumes of Science, 100 volumes of the Journal of Geophysical Research, and ...

... " on the deepsea floors, where hydrothermal vents supply the energy and chemicals necessary for life. Here are found free-living bacteria, tube worms, molluscs, and several other species that prosper without the benefit of photosynthesis. These chemosynthetic, thermal-vent communities are separated by thousands of kilometers of sea-floor "desert." Yet, the species involved are similar worldwide and must, at some time, have crossed these wide, forbidding expanses. One possible mechanism for this mysterious dispersion came in 1987, when the research submersible Alvin chanced upon the remains of a 21-meter whale at a depth of 1,240 meters off California's coast. The whale's skeleton was covered with bacterial mats like those at the hydrothermal vents. Also sustained by the carcass were mussels, snails, and worms; all in all, a community much like those at the vents. Furthermore, many of the species partaking of the whale's energy and chemical resources are not normally found in that part of the Pacific. Subsequently, more "whale falls" with attached biological communities were found elsewhere. Calculations suggest that whale falls are more common that one might suppose -- perhaps occurring with average spacings of only 25 kilometers. They could very well be the stepping stones that allow hydrothermal vent communities to disperse across the abyssal deserts.

... ocean waters. First, abundant plant life has been found at depths of up to 268 meters, well beyond the 200-meter limit biologists had set based on the availability of sunlight. It wasn't difficult to discount photosynthetic life at 268 meters, because light there is only 0.0005% that at the surface. But there it was; and it may be found even deeper now that we've taken off the blinders. (Littler, Mark M., et al; "Deepest Known Planet Life Discovered on an Uncharted Seamount," Science, 227:57, 1985.) The second discovery came at 10,000 feet in the Gulf of Mexico. There, scientists in the submersible Alvin found a well-developed community of large clams, crabs, mussels, and tube worms, which closely resembles those around the Pacific hydrothermal vents. These life colonies do not use sunlight at all, nor do they depend on other life forms based on solar energy. They employ chemosynthesis, and the hydrogen sulfide and other substances in the vented waters replace sunlight. Although there are no obvious vents at the Gulf of Mexico site, the waters there contain plenty of hydrogen sulfide, indicating seepage from somewhere. The life forms are all new to science, although they resemble those in the Pacific. (Anonymous; "Worms without Vents," Oceans, 17:50, September/October 1984.) Comment. Question: how do non-mobile life forms travel the great distances from one vent or seepage locale to another? It seems as if ...
