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...
...women: Kathryn Sullivan, who is scheduled this week to become the first American woman to walk in space, and Sally Ride, the first U.S. female astronaut. Also aboard is Marc Garneau, the first Canadian astronaut, an engineer who will study the damage done to Canadian lakes by acid rain. Within hours after the launch, Ride commanded the shuttle's robot arm to release a $40 million heat-sensing satellite that will aid long-range weather forecasting.
