Tapping the Power of Rap
The acoustic waves from rap music may help power miniature medical sensors implanted in the body.
A device developed by researchers at Purdue University’s Birck Nanotechnology Center harnesses the frequency of music to cause a cantilever to vibrate and generate electricity. Rap’s strong bass component is particularly useful because of its low frequency; also, the frequency changes continually, allowing the sensor to switch between storing electrical charge and transmitting data.
The rap-powered sensor could aid the treatment of individuals with aneurisms or incontinence due to paralysis.

Why the Future Will Almost Certainly Be Better than the Present
Five hundred years ago there was no telephone. No telegraph, for that matter. There was only a postal system that took weeks to deliver a letter. Communication was only possible in any fluent manner between people living in the same neighborhood. And neighborhoods were smaller, too. There were no cars allowing us to travel great distances in the blink of an eye. So the world was a bunch of disjointed groups of individuals who evolved pretty much oblivious to what happened around them.

Where is the Future?
Like the road you can see ahead of you as you drive on a journey, I suggest the future is embedded in emerging, continuous space-time.

Transparency 2013: Good and bad news about banking, guns, freedom and all that
“Bank secrecy is essentially eroding before our eyes,” says a recent NPR article. ”I think the combination of the fear factor that has kicked in for not only Americans with money offshore, countries that don’t want to be on the wrong side of this issue and the legislative weight of FATCA means that within three to five years it will be exceptionally difficult for any American to hide money in any financial institution.”
