THE OPENING of a high-speed data link between the US and continental Europe last week gave a fillip to international collaboration among scientists. The existing transatlantic data links have until now allowed only thousands of bits of data to be transmitted per second. The new link, called fatpipe, has a capacity of 1.5 megabits per second, the equivalent of 200,000 characters per second. IBM, Merit Computer Network and MCI, an American telecommunications company, are providing the equipment and software for the link. They are also making space on an existing transatlantic optical fibre for fatpipe. They would not say, however, how much they are spending. The advantage to scientists, says Stephen Wolff of the US’s National Science Foundation, is that files will travel faster than before. In addition, he says, computers on one side of the Atlantic will respond more quickly to commands from those on the other side. By increasing capacity, more researchers will be able to communicate with each other at the same time. Initially, fatpipe will improve data links between US physicists and their colleagues at CERN, the European centre for particle physics in Geneva. Eventually,
