...assailants in all cases are Great Whites, which can grow to more than 20 ft. long and weigh up to 3½ tons. Many biologists trace the sharks' increasing aggression to recent rulings like the U.S. Marine Mammals Protection Act of 1972. That law makes it illegal to hunt pinnipeds like sea lions, elephant seals and sea otters, all staples of an adult shark's diet. Fifteen elephant seals lived in the Red Triangle area in 1961; by 1984 there were 5,000. The sea lion population has been increasing by 5% a year. As a result, Great...
Like Henry Ford, Merrifield gained fame by automating a complex process. Proteins, produced inside living cells, are made of long chains of chemically linked amino acids, which group into units known as peptides. To understand a wide variety of biological processes, scientists must be able to trace the sequence of amino acids in a protein. They must know how to duplicate that sequence to manipulate its components for research. Before Merrifield developed his technique, biologists labored through dozens of painstaking purification procedures, taking months or even years to synthesize a peptide chain...
Most impressive was freshman goalie Trace Whitley, who has given up just five goals in 13 games on route to recording the record breaking nine shutouts...
...brought up at least $27 million worth of gold, precious gems and artifacts from the wrecks of the Spanish galleons Santa Margarita and Atocha, which sank in 1622. The company found the sister ships in waters about 50 ft. deep off the Florida Keys. During the continuing quest to trace the path of debris scattered as the ships broke apart, Treasure Salvors has videotaped the search area from the air; the shallowness and clarity of the water enable detection of such important visual clues as scars on underwater reefs...
...fixed part of espionage jargon. And while Le Carne and others like him explore the professional side of the celebrated case, others concentrate on the story's personal dimensions. This summer's highly acclaimed film, Another Country, based on the play of the same name, seeks to trace the roots of radicalism and betrayal to the disillusionment with the class power and sexual politics of British boarding schools...
