Low-frequency radio waves can kill zebra mussels, which cause millions of dollars in damage by clogging water intake pipes at power plants and other installations, researchers reported Tuesday at an American Chemical Society meeting. Zebra mussels in an aquarium that were exposed to very low frequency electromagnetic waves--about 60 hertz, similar to what is emitted by a power outlet--died within 40 days, according to researchers from Purdue University-Calumet in Hammond, Ind.

In its biggest acquisition so far, Irvine chip maker Broadcom Corp. said Tuesday it would buy a company that develops the wireless bluetooth technology for stock worth $457.1 million. Bluetooth, a hot new arena, uses radio frequencies instead of wires or cables to let electronic devices communicate with each other and over the Internet at short ranges. Broadcom, which makes high-speed communications chips, will issue 3 million shares for the 87% of Innovent Systems Inc.
