Should scientists be allowed to create extremely aggressive and highly infectious influenza viruses? Dutch virologists have done it and, in the process, triggered a fierce debate over the risks of bio-terrorism and the potential release of deadly viruses.

The 17th floor of the Erasmus Medical Center in the Dutch city of Rotterdam certainly doesn't look like the kind of place that could pose a threat to global security. A disco ball hangs from the ceiling in the hallway in front of the elevators, and a bar with a golden beer tap stands in the corner of the conference room.

Everything in this 1960s high-rise building evokes the charm of student life, including the door to Room 17.73, which is covered with colorful stickers. But some view the scientist who sits behind that door as a threat to mankind.

Ron Fouchier, a giant of a man at more than two meters tall (6'6"), has dark circles under his eyes. His life has been stressful lately. "They want to paint me as a homicidal idiot," he says heatedly. He is referring, most of all, to a powerful institution from the United States, the National Science Advisory Board for Biosecurity (NSABB).

In his work Fouchier, a virologist, uses the methods of a branch of research that is as booming as it is controversial. Synthetic biology employs targeted manipulation through genetic engineering to construct new organisms. The 45-year-old's research has even set off alarm bells at the World Health Organization (WHO). This week, Fouchier will appear before an international panel of experts at the WHO to explain his experiments.
