Last week President Johnson decreed an end to the exile of the Bikinians, now a scattered community of 500. After 23 atomic and hydrogen bomb tests, the last in 1958, the poisons of nuclear radiation have dissipated from the sand and sea around their native atoll, and the Bikinians can at last return to their home...
...distinguished member of the Soviet Academy of Sciences and a Stalin prizeholder who helped develop Russia's hydrogen bomb, Sakharov condemns the imprisonment in labor camps of Authors Yuli M. Daniel and Andrei Sinyavsky and other intellectual dissidents. He demands the release of all political prisoners. As if that were not bad enough, he says that Russia must "without doubt" support the democratic reforms in Czechoslovakia. Though he censures U.S. involvement in Viet Nam, he also blames the outbreak of the Middle East war on Russia's "irresponsible encouragement" of the Arabs, charges that Russia's continued...
...molecule delivers its oxygen to the body's tissues, it reverts to its original shape and attracts charged hydrogen atoms. The blood thus becomes alkaline, forms a temporary chemical bond with carbon dioxide and water from the tissues in the form of bicarbonate and carries it to the lungs, where it changes back into water and carbon dioxide before being exhaled. The change of molecular shape is important, says Perutz, "because it is the most elementary manifestation of the property of a living system that can turn chemical energy into movement...
These organic compounds made of carbon, nitrogen, hydrogen and oxygen resemble ordinary liquids. Yet their orderly molecular structure is similar to that of solid crystals such as diamonds, mica and quartz. The crystals themselves are not new, but it was only recently that scientists discovered that an electrical charge makes them light-reflecting; the higher the voltage, the greater the reflecting power. At first, this "electro-optical effect" could be shown only in the laboratory, since the crystals reacted to electricity only at certain temperatures. Now, after trying more than 100 compounds, RCA scientists have produced a crystal that responds...
...most people today, the word brings to mind a fetchingly skimpy swimsuit. Few now recall that Bikini was the site of the world's fourth atom ic detonation and the cradle of the hydrogen bomb. It has been 22 years since the atoll's docile people were banished by the atom, and gentling nature and the passage of time have leached away Bikini's residual radiation. Lush vegetation once more covers the island. Through their long exile, most of it on inhospitable, isolated, mosquito-plagued Kili Island, the 300 or so Bikinians have huddled in a beachfront...
