Merrifield confined his simple process to a single laboratory container. Placing a microscopic polystyrene bead inside the receptacle to act as a solid, inert foundation, he began adding drops of amino acid units, which linked together in the proper order. He washed the growing chain in a purifying solution after adding each chemical, thus avoiding the possible need to remove any part for additional purification, as in past methods. When the protein was complete, acid was used to cleave it from the bead. Though Merrifield's first device, regulated by a metal cylinder studded with pegs, had a touch...
...weapon might be terminated altogether. The Army had planned to buy 618 of the guns by 1987 (estimated cost: $4.5 billion). Before a Senate subcommittee, Lieut.

Not since Kruschev came to America in the 1960s has a Russian or an American bead of state visited the other country during their tenure. Reagan, indeed, seems to have a grand imaginative disdain for Russia, as if it were really not a country worth visiting, but a land where savage Darth Vaders punish and abuse helpless Ivan and Vanyas. Unfortunately for Mr. Reagan...
