Science Frontiers ONLINE No. 112: Jul-Aug 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Dolphin Refrigerators Dolphins and other cetaceans have an overheating problem. For high hydrodynamic performance, their bodies must be nicely streamlined. For males, this means that their testicles must be stored internally. But dolphins are very active animals, and their muscles generate considerable heat -- too much heat for sperm to survive without some sort of special cooling system. (Recall that human males with undescended testicles may become sterile.) Since dolphins are obviously procreating, evolution must have come to the dolphins' rescue. Evolution's engineering solution installs heat exchangers in the dolphins' tails and dorsal fins. Blood heated in the vicinity of the testes is ... through special veins in the tail and dorsal fin, where it is cooled by seawater and then returned to the dolphins' heat-sensitive innards. Female dolphins have similar heat exchangers to cool their uteri. The same article in Discover points out still another remarkable adaptation conferred on dolphins: They do not have to expend a lot of energy in diving to great depths. Below about 70 meters, the water pressure collapses their lungs so that they sink like rocks! Of course, returning to the surface does require some exertion. (Zimmer, Carl; "The Dolphin Strategy," Discover, 18:72, March 1997.) Comments. One automatically supposes that the dolphin dorsal fin is needed for stabilization when swimming -- like an airplane's rudder. But several cetacea do ...

Science Frontiers ONLINE No. 17: Fall 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Saturn Is Still Cooking Away Observations from the earth and the Pioneeer spacecraft have long puzzled astronomers because they indicate that Saturn is radiating much more internal heat than it should. This anomaly leads to the outrageous possibility that Saturn is actually very young and has not cooled off as much as we would expect from theory. The infrared detector on the recent Voyager-1 flyby seems to show that the atmosphere of Saturn possesses only about half as much helium as theory would have. The surmise is that the missing helium is still residing in the planet. This might account for some of the abnormal heat generation. (Anonymous; "Puzzling over Saturn's ... Heat," Eos, 62:538, 1981.) Comment. Thus, the excess-heat anomaly may be replaced by the missing-helium anomaly. Curiously, some ancient myths refer to Saturn as the "sun of night." Could Saturn have been much brighter not too long ago? From Science Frontiers #17, Fall 1981 . 1981-2000 William R. Corliss ...

There is simply not enough helium escaping from earth's crust to account for the heat flowing outwards from our planet's core.

The final report on the fatal explosion of a cold-fusion experiment at SRI International (SF#80) blames a loose piece of Teflon that may have blocked a gas outlet tube. Possible scenario: After many hours, the researchers finally noticed something was awry. When A. Riley lifted the cell from its water bath, it exploded. "The investigators believe that hot palladium ignited the pressurized mixture of oxygen and deuterium. The bottom blew off the cell, turning the rest of it into a rocket which shot upwards at 50 metres per second. It struck ... which power was generated by cold fusion. "Edmund Storms, a high-temperature chemist at Los Alamos, used palladium metal supplied by Japanese fusion researcher Akito Takahashi of Osaka University."

Japan's Ministry of Trade and Industry (MITI) plans to launch a five-year program to study cold fusion. Isn't this folly, since most physicists have declared cold fusion to be impossible?

If Carnot life is possible, it may well have evolved in such dark and distant places -- making life abundant throughout the Universe.

But how did these radioactive specks get lodged inside the hollow tubes which themselves are encased within diamonds?

The recent Third International Conference on Cold Fusion, held in Nagoya, Japan, drew 350 participants, including 50 from U.S . corporations and government laboratories. Hardly a wake! But also hardly a confirmation. Even with new results frequently reported, the incontrovertible, reproducible proof of cold fusion demanded by the scientific community still is lacking. A written confrontation between cold fusion protangonists and antagonists appeared in the March 1994 issue of Physics Today. The "pro" position was stated by E. Mallove, editor of ... J.R . Huizenga, author of the debunking book: Cold Fusion: The Scientific Fiasco of the Century : "In contrast to Mallove's declaration that cold fusion is a "spectacular new form of lattice-induced nuclear energy," I conclude that there is no persuasive evidence to support this far-out claim. Instead, cold fusion as a nuclear process producing watts of excess heat is more likely than not to be an example of pathological science." Of historical interest in this collection of correspondence in Physics Today was S. Bashkin's mention of the 1926 experiments of F. Paneth. His results were essentially identical to those of S. Pons and M. Fleischmann that began the present cold fusion furor. Paneth detected helium after passing an electrical current through hydrogen ...
