Magnetic signals could cure chronic insomnia
Make no mistake, there's a plethora of devices out there aimed squarely at rudely disrupting your nap, but a technique that utilizes a gaudy head wrap and magnetic pulses could make the process of conking out a whole lot easier. Apparently, scientists can use relatively standard medical equipment in order to "stimulate the brain with harmless magnetic pulses," which essentially penetrate the nerves that control a type of deep sleep called "slow-wave activity." By forcing the brain to conjure these waves, it helps trigger deep sleep in even the "most chronic insomniac," and researchers are hoping that these methods could be used to create a machine that lets weary individuals get one fabulous power nap. Until then, however, may we suggest wading through every last Intel roadmap presentation you can find without ever losing focus, as this little trick seems to work quite well in corporate settings.[Via Spluch]
Widget Watch: Deep Sleep
Safe Sleep is basically a 'deeper sleep' feature that debuted on the 15-inch and 17-inch PowerBooks last year, and as far as I know, it's included (and enabled by default) on all of Apple's MacBook/Pro portables (and yes, I hear it's basically like the Windows 'Hibernate' state). This deep sleep differs from the typical Sleep state that most of us are used to: it writes everything currently in memory (your open apps, the files you're working on, etc.) to the hard drive, and actually powers down the machine, saving the battery power that slowly siphons during the normal Sleep mode. Waking from this mode naturally takes a little longer, and a progress bar unique to this feature is displayed while the machine is waking from Safe Sleep. If you want to see it in action, Rob Griffiths (of Macworld and Mac OS X Hints fame) posted a good video demonstration of Safe Sleep on his black MacBook (so jealous!) to YouTube. By default, the new MacBook/Pro behavior is to use a little of both worlds: they write everything to the drive while they're going to sleep, but still use 'regular Sleep' unless power is lost from both AC and the battery. If power is lost, the machine switches over to Safe Sleep automatically - yet another reason to send those Apple engineers a batch of cookies. But what if you want to bypass the regular Sleep status and use Safe Sleep by default all the time?Enter the Deep Sleep Dashboard widget - one-click access to putting your Mac down for an extended nap. Documentation is included with the widget explaining what's going on, and it also has a list of the machines known to support this feature. To top things off, if you just aren't a fan of widgets, the author also packaged Deep Sleep as a simple command line utility, linked in small print at the bottom of Deep Sleep's page.[via MacUser]
