Back in the Whelan Lab, April is labeling petri dishes with a permanent marker—preparing to infect her cells. Then she hurries to the lab bench for another step and back to the fume hood, which keeps the chemicals she works with contained. The doctor’s appointment has put her behind schedule...
...gave the hybrid viruses the ability to spread easily among the lab mice. Scientists think the protein may allow hybrid viruses to grow more efficiently in the lower temperatures of the upper respiratory tract, from which the virus can more easily spread to others. (The H5N1 virus tends to infect the lower respiratory tract in humans, where it can't easily get out and spread...
...more than four times the euro zone's 3% limit. The European Commission blasted Greece for the faulty stats, and ratings agencies downgraded Greek debt, sending yields on government bonds skyrocketing. Over the past two months, as fears have grown that Greece's poisonous finances could infect the rest of Europe, the euro has slipped by almost 7% against the dollar.

...Such cyberbattles are already happening in miniature. In Afghanistan and Iraq, U.S. cyberwarriors are hard at work denying enemy commanders the ability to direct their forces, the senior Pentagon officer says.

"I can alter the messages coming across," he says...
...malaise at the lab, which Ho attributes to personality conflicts among the faculty, began to infect the quality of the science. In 2002, Ho generated headlines when he thought he had found the X factor made by immune cells that protected some people from developing AIDS. It turned out, however, that his conclusion was premature. Other cells had contaminated his results, and he was forced to issue a "retraction of an interpretation" of the paper describing the study. "It was an embarrassing moment for us, but we fixed it ourselves," says Ho. "It was certainly a low point...
