Transcranial magnetic stimulation, a technique for treating clinical depression, uses a device placed on a patient's head that delivers a pulse to the gray matter. Psychiatrists at the American Psychiatric Association meeting here are unabashedly optimistic about its potential for treating tough cases. It's in the final stages of FDA review, and could come to market as soon as the end of the year.
TMS works by creating an electromagnetic pulse that doesn't disturb the skull or scalp, but can reach two to three centimeters into the brain to stimulate the prefrontal cortex and paralimbic blood flow, increasing the serotonin output and the dopamine and norepinephrine functions.

The creator of Jabber, Jeremie Miller, is joining Wikipedia founder Jimmy Wales in building and open-source, community-driven search service called Search Wikia. They believe transparent algorithms and open-source code is a better alternative than proprietary engines. Now, with the addition of Miller, the are expanding the effort to include developing a standardized protocol for exchanging information between search engines, enabling distributed, collaborative search. They anticipate that such a service may have many of the same features, but also weaknesses, as Wikipedia such as the posting of inaccurate information and companies trying to influence what is posted.
