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 to the Science Frontiers newsletter are no longer available.

Compilations of back issues can be found in Science Frontiers: The Book, and original and more detailed reports in the The Sourcebook Project series of books.

Science Frontiers ONLINE No. 92: Mar-Apr 1994 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects High Temperature Suppresses Radioactive Decay Environmental conditions are not supposed to affect nuclear reactions in general or radioactive decay rates specifically. This is one reason why cold fusion got the cold shoulder from most physicists. Now for the "however" that is the hallmark of Science Frontiers : "Thirty years ago, Otto Reifenschweiler was searching for a compound which could protect Geiger-Mueller tubes from damage when they are first ionised. He found the compound, which became a money-spinner for Philips, in a mixture of titanium and radioactive tritium. He also discovered that as the mixture was heated, its radioactivity declined sharply. No process known to physics could account for such a baffling phenomenon: radioactivity should be unaffected by heat. Nevertheless, as the temperature increased from 115 C to 160 C, the emission of beta particles fell by 28%." Reifenschweiler and his colleague, H. Casimir, put this discovery on the backburner and concentrated on the Geiger-Mueller tubes. The recent furor over cold fusion impelled them to resurrect the work and publish it in the January 3 issue of Physics Letters A . Is there a new phenomenon here? Is it relevant to cold fusion? It may be pertinent that some common fusion reactions also employ tritium. (Bown, William; "Ancient Experiment Turns Heat Up on Cold Fusion," New Scientist, p. 16, January 8, 1994.) Comment. How many other potential ...

... Science Frontiers ONLINE No. 96: Nov-Dec 1994 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Cold fission?That's right: "fission" not "fusion." A recent number of Science News carries an intriguing suggestion from J. Brind: "Has anyone considered the possibility that the anomaly of "cold fusion" experiments -- high energy yields with few neutrons or tritium nuclei -- might result from a case of mistaken identity? There are a number of nuclear fission reactions that produce neither neutrons nor tritium, yet yield large quantities of energy." One such reaction is: 7Li+ 1H = 2(4He)+ 17.3 MeV. This is a very clean nuclear reaction that might one day be harnessed for everyday use, given lithium's low cost and abundance. The "cold fusion" effects could well come from captures of deuterons by 6Li, which is present in natural lithium. (Brind, Joel; "Cold Fission?" Science News, 137:163, 1994.)

... geo-physicist at Brigham Young, suggested the possibility as long as three years ago! We have not seen Palmer's speculation in print, but the stimulating effect of anomalies on scientific research is reassuring, whatever the final outcome of the cold fusion wars. The same New Scientist article supports the above speculation as follows: "Calculations show that more than enough deuterium finds its way into the upper mantle by this route (seawater in subduction zones) to account for the heat emitted by the Earth's core, although the heat obviously comes from other sources as well. The rate of fusion of deuterium nuclei required to produce the observed rations of helium-3 to helium-4 in rocks, diamonds and metals is similar to that observed by Jones in his experiments with electrolytes. Tritium can also be a product of the fusion of deuterium. Jones and his group say that the tritium detected in the gases from volcanoes is further evidence of cold fusion." Jones has also wondered whether Jupiter's excess heat could be generated deep within the icy planet via cold fusion. (Anonymous; "Rocks Reveal the Signature of Fusion at the Centre of the Earth," New Scientist, p. 20, May 6, 1989.) From Science Frontiers #64, JUL-AUG 1989 . 1989-2000 William R. Corliss ...

... . Bockris stated that Japan has organized a fusion institute where more than 80 scientists are "rapidly moving forward to develop cold fusion." Bockris himself has achieved positive cold-fusion results in his lab at Texas A&M . Another panel member, R. Huggins from Stanford, who has also replicated Utah's cold fusion results, remarked that several other U.S . labs have achieved excess power levels of 10-30 watts/cc. (Anonymous; Access to Energy , p. 4, October, 1989. Cr. P.F . Young) Despite positive results like those mentioned above, a recent report in Nature, by scientists at Cal Tech and the University of California, states emphatically that they can find no excess heat, neutrons, gamma rays, tritium, or helium in their cold-fusion experiments.

... Science Frontiers ONLINE No. 69: May-Jun 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Fracto-fusion?The hot topic in cold fusion research is now fracto-fusion; that is, the inducing of deuterium fusion by means of the electric fields established along microcracks developing in substances charged with deuterium or tritium. Back in 1986, Soviet researchers reported the observation of neutron emission when they violently crushed lithium deuteride in the presence of ice made from heavy water. More recently, they saw the same phenomenon when milling several deuterium-containing metals. Conceivably, deuterium nuclei accelerated by the electric fields along the cracks could be fusing, producing neutrons. (Amato, I.; "If Not Cold Fusion, Try Fracto Fusion," Science News, 137:87, 1990.) Pouring cold water on the Soviet results, two American scientists described negative results in the February 15 issue of Nature. They fired small (0 .131-gram) steel ball bearings at an ice tar-get made with 99.9 % deuterium. Despite the violent shattering of the deuterated ice, no significant numbers of neutrons were measured. (Sobotka, L.G ., and Winter, P.; "Fracture without Fusion," Nature, 343:601, 1990.) Comment. Whatever the fate of fractofusion, several labs around the world are still pursuing cold fusion. The sci entific mainstream, though, considers cold fusion a dead issue, even though anomalous neutrons and heat emission have been found ...
