Chemist Thomas R. Cech received an honorary doctor of science degree. A 1989 Nobel laureate in chemistry, Cech is currently the director of the Colorado Institute for Molecular Biotechnology at the University of Colorado. Cech's research served a pivotal role in the discovery that RNA can act as an enzyme—a function that had previously been viewed as exclusive to proteins. In 1987, Cech was elected to the U.S. National Academy of Sciences and was awarded a lifetime professorship by the American Cancer Society...
Directed evolution—the method of artificially inducing natural selection to evolve desirable proteins or RNA not found in nature—is highly difficult to study in a laboratory setting, according to physics professor David A. Weitz, an author of the study...
...Stephen J. Elledge, a professor of genetics at Harvard Medical School and head of the lab in which the study took place. With this understanding, Elledge and his team systematically deactivated every gene in the human genome—testing some 20,000 different genes—using new RNA interference technology, hoping to determine the genes in the host cells that the virus relied upon for infection...
...global financial meltdown weren’t enough, this spring introduced scary words like “novel virus” and “pandemic,” bumping the financial crisis off the headlines. The attention-grabbing RNA virus took the world by surprise and, thanks to air travel, spread rapidly from its origin in Mexico to every continent. The virus’ spread was a perfect storm of mutation (a combination of swine, human, and avian elements), little to no human immunity, and no available vaccine against it. To make matters worse, everyone was touting its similarity...
Rathore used a new technique, called RNA interference, to construct a genetic sequence that blocked the gossypol-producing enzyme in the seeds only. After succeeding in the lab, he began a test in a greenhouse to see if the genetically modified cotton plant would survive and pass on its new trait. Rathore's just-compiled data show that the modified cotton appears to be normal in every way other than the fact that it has instantly edible seeds. "What works in the greenhouse should hold true in the fields," he says...
