According to the Physical Review, a group of scientists at the University of California (Albert Ghiorso, G. Bernard Rossi, Bernard G. Harvey and Stanley G. Thompson) have created Element 99, the heaviest so far. They did it by bombarding Uranium 238 (Element 92) with a beam of positively charged nitrogen atoms from a 60-inch cyclotron. The nitrogen atoms contained seven protons and seven neutrons, and when they collided with U-238, all except five of the neutrons joined its nucleus. The seven added protons raised the atomic number to 99, and the added neutrons and protons together raised...
...Extreme pessimism regarding cancer of the lung is no longer justified, said the University of Tennessee's Dr. Duane Carr. Even in cases which are found too late for surgery to help, deep X-ray treatments and drugs (nitrogen mustard and triethylene melamine) will relieve pain and prolong life...

...suit, using only a mouthpiece breathing apparatus to equalize the tremendous pressures of the ocean's silent world. Unlike Captain Cousteau, who brought the silent world on to the printed page in a 1953 bestseller (TIME, Feb. 9) Root often said that he had never suffered from the nitrogen narcosis which Cousteau calls also "the rapture of the depths...
Working in their separate ways, 3,000 miles apart, the two researchers tackled some of the most complex and fundamental problems in the biological processes by which food is converted into energy. Krebs had already shown that urea, the end product of nitrogen metabolism, is formed through a cycle of chemical reactions in the liver. Soon he was delving into a still more important cycle, by which products of sugar and fatty acids are broken down into a group of chemicals including pyruvic acid. This acid is oxidized or "burned" to form a go-between chemical now known as acetyl...
