单选题In 2010, a federal judge shook America's biotech industry to its core. Companies had won patents for isolated DNA for decades—by 2005 some 20% of human genes were parented. But in March 2010 a judge ruled that genes were unpatentable. Executives were violently agitated. The Biotechnology Industry Organisation (BIO), a trade group, assured members that this was just a "preliminary step" in a longer battle. On July 29th they were relieved, at least temporarily. A federal appeals court overturned the prior decision, ruling that Myriad Genetics could indeed holb patents to two genes that help forecast a woman's risk of breast cancer. The chief executive of Myriad, a company in Utah, said the ruling was a blessing to firms and patients alike. But as companies continue their attempts at personalised medicine, the courts will remain rather busy. The Myriad case itself is probably not over Critics make three main arguments against gene patents: a gene is a product of nature, so it may not be patented; gene patents suppress innovation rather than reward it; and patents' monopolies restrict access to genetic tests such as Myriad's. A growing number seem to agree. Last year a federal task-force urged reform for patents related to genetic tests. In October the Department of Justice filed a brief in the Myriad case, arguing that an isolated DNA molecule "is no less a product of nature.., than are cotton fibres that have been separated from cotton seeds. " Despite the appeals court's decision, big questions remain unanswered. For example, it is unclear whether the sequencing of a whole genome violates the patents of individual genes within it. The case may yet reach the Supreme Court. As the industry advances, however, other suits may have an even greater impact. Companies are unlikely to file many more patents for human DNA molecules I most are already patented or in the public domain. Firms are now studying how genes interact, looking for correlations that might be used to determine the causes of disease or predict a drug's efficacy, companies are eager to win patents for 'connecting the dits', explains Hans Sauer, a lawyer for the BIO. Their success may be determined by a suit related to this issue, brought by the Mayo Clinic, which the Supreme Court will hear in its next term. The BIO recently held a convention which included seddions to coach lawyers on the shifting landscape for patents. Each meeting was packed.

单选题In an age of perpetual digital connectedness, why do people seem so disconnected? In a Duke University study, researchers found that from 1985 to 2004, the percentage of people who said there was no one with whom they discussed important matters tripled, to 25%; the same study found that overall, Americans had one-third fewer friends and confidants than they did two decades ago. Another recent study, by researchers at the University of Michigan, found that college students today have significantly less empathy than students of generations past did. The reason, psychologists speculate, may have something to do with our increasing reliance on digital communication and other forms of new media. It's possible that instead of fostering real friendships off-line, e-mail and social networking may take the place of them—and the distance inherent in screen-only interactions may breed feelings of isolation or a tendency to care less about other people. After all, if you don't feel like dealing with a friend's problem online, all you have to do is log off. The problem is, as empathy wanes, so does trust. And without trust, you can't have a cohesive society. Consider the findings of a new study co-authored by Kevin Rockmann of George Mason University and Gregory Northcraft at the University of Illinois who specializes in workplace collaboration. Northcraft says high-tech communications like e-mail and (to a lesser extent) videoconferencing—which are sometimes known as "lean communication" because they have fewer cues like eye contact and posture for people to rely on—strip away the personal interaction needed to breed trust. In a business setting—as in all other social relationships outside the workplace—trust is a necessary condition for effective cooperation within a group. "Technology has made us much more efficient but much less effective," said Northcraft in a statement. "Something is being gained, but something is being lost. The something gained is time, and the something lost is the quality of relationships. And quality of relationships matters." In Rockmann and Northcraft's study, 200 students were divided into teams and asked to manage two complicated projects: one having to do with nuclear disarmament; the other, price fixing. Some groups communicated via e-mail, some via videoconference and others face to face. In the end, those who met in person showed the most trust and most effective cooperation; those using e-mail were the least able to work together and get the job done. Northcraft thinks this is because real-life meetings, during which participants can see how engaged their colleagues are, breed more trust. Over e-mail, meanwhile, confirmation of hard work gets lost, which tends to encourage mutual slacking off.
