MYLER '"""United Ptm International Washington - (UP!) - Radio Moscow grabbed and held the 'world's attention for a while last month with a bogus story t about a couple of salamanders : ' It said were revived after 5.000 years in the Siberian deep freeze. '-'Scientists snickered or snorted, according to their - dispositions. The same story speculated 'It- might be a good plan to . " freeze astronauts of the fu ture to enable them to endure Hong space flights. This may turn out with time to be as farfetched as the tale of the resuscitated salamanders. But at the mo ment serious scientists are seriously discussing suspend ed or reduced animation to stretch out crew supplies on space voyages lasting for years. Perhaps the most re spectable ideas along this line have to do with hypothermia, the reduction of body temper ature below the normal 88.6 degrees. Hypothermia is used in some kinds of heart and kid ney surgery and in treatment of certain brain injuries. Reduce Animation Applied to space pilots, hy pothermia would reduce but not entirely suspend anima tion. Air Force doctors have estimated that a relatively slight powering of the body temperature to 86 degrees would cut down activity of the cells and organs by SO per cent. In the case of a hibernating animal with a body temper ature of 39.2 degrees, con sumption of oxygen is re duced to three to eight per cent of normal. Such a reduc tion would mean a great cut in spaceship weight when you consider that an astronaut needs about 1.13 pounds of oxygen per day. Capts. T. K. Cockett and Cecil C. Beehler of the Air Force medical corps at Brooks Air Force Base, Texas, esti mated a space pilot in a normal state would have to take along a minimum of 5,000 pounds of supplies for a roundtrip to Mars lasting 17 months. This could include oxygen, water, food, and material to neutralize carbon dioxide ex haled by the pilot. Assume a three-man crew for the Mars flight, and you have a require ment for supplies weighing five times the entire Mercury space capsule. Protect Astronauts In addition to cutting down consumption, hypot h e r m I a also would protect astronauts from many of the stresses of space flight and from danger ous radiations. The Air Force doctors said tolerance to radiation "may be increased many-fold" by a comparative small lowering of body temperature. Hypo thermia, however, produces some bad side effects. A better method of reduc ing animation, if it were pos sible, would be to induce in astronauts a state similar to that of animals in the deep sleep of hibernation. If a drug could be made which would induce hiberna tion, the doctors said, the re sults would be "tremendous savings" in supplies and a great load off the mind of rocket engineers concerned with spaceship weight problems. Other scientists have esti mated that in hibernation an astronaut's con sumption of food and oxygen might be only a hundredth that of an active man. Bats Live Longer It appears that some hiber nating bats live 20 times long er than nonhibcrating animals of the same body weight. A few years ago Albert R. Dawe, chief scientist of the Chicago branch of the office of naval research, took this bat statistic, applied it to space traveling man, and came up with what he called MILD CHEDDAR CHEESE ANY SIZE PIECE n p -J STEWING CHICKEN Plump-2 to 3 Pound WHOLE DRANK SWIFT'S SANDWICH BOLOGNA BY THE PIECE ....

' "In h i b e r n a tion," Dawe said, "man's arrest ol time might be such that he could possibly exist for about 20 normal lifetimes, or 1,400 years." Entirely suspended anima tion might accomplish even greater wonders. The story of the frozen salamanders un doubtedly was, as one Soviet scientist said, "pure fantasy." But may it not become pos sible some day to preserve people indefinitely in deep freezers? There is a new branch of science called cryo biology. It deals with the cooling of cells and tissues of temperatures hundreds of de grees below freezing. Male Germs Revive This has been proposed as a means of preserving blood and tissue cultures. Male, germ cells have been successfully frozen and revived by cryo biological techniques, and so have fertilized rabbit eggs. The trick seems to be ex tremely quick freezing and similarly quick thawing. This prevents formation of ice , crystals which rupture and '; destroy tissue. It has been found that liv ing cells cooled to the tern- , pcrature of liquid nitrogen, around 320 degrees below zero, cease practically ' all . activity. , . . In a discussion of cryobiolc- gy a while back. Dr. Joseph ... F. Saunders of the office of naval research did not go Into , its possible application to , space flight. But he said it may become feasible in the far future to preserve living plants and anl mals by deep freezing meth- -ods to prevent the extinction of a threatened species. -- "Such an a p p 1 i cation," Saunders said, "cannot be die- . polled as being impossible or fantastic. Theoretically, life docs experience a temporary halt at temperatures around and below the liquid nitrogen range." - . a -v. i a-i?, 1 ,lSf it 4 I .
