...want to find Peter Vitousek in his lab, the first thing you have to do is go to Hawaii. After that, it gets tricky, because Vitousek's lab isn't in the state--it is the state. The Stanford University ecologist has devoted his career to studying the earth's metabolism and life cycles, zeroing in on how the intricate machinery of its forests is altered by people and the introduction of new plants and animals. "Peter is a real visionary," says marine ecologist Jane Lubchenco of Oregon State University. "It's unusual to have someone who is simultaneously interested...
...materials used in these systems are designed. Researchers in the past had relied on off-the-shelf materials for medical applications. (The fabric in the first artificial heart, for example, was the same polyether urethane used in women's girdles.) Langer reversed the search process; in his lab, researchers first determine the exact physiological requirements of a system and then design a polymer to meet those specs...
...assignment in Folkman's lab was to find a way to release gradually a stream of large organic molecules into the tissue of a laboratory animal. Researchers had already tried encasing large molecules like the one Langer was testing in polymers (long-chain molecules, such as silicone, that are semipermeable to certain types of molecules). Unfortunately, this particular molecule--like most of the new drugs being created in biotech labs--was much too large to fit through the tiny holes in any of the available polymers. The problem, polymer experts told Langer, was unsolvable...
...said it. My chest aches less. Early this morning I walked out the front door and bent and picked up the morning paper. Cool air, distant traffic, a whiff of lilies from along the driveway, and in the park across the street, a woman loping along with a yellow Lab. After a heart operation, it is all indescribably beautiful...
...murder. Many of those set against embryonic stem cell research advocate using adult stem cells, but while scientists have had some success using stem cells culled from adults, they?ve found that embryonic stem cells hold particular promise. They are more easily molded, more susceptible to manipulation in the lab...
