Cell phones as Credit Cards
ante_up writes "We should have known this was coming. Business Week reported that Japanese carrier NTT DoCoMo Inc. (DCM ) is vamping up their cell phone technology. First they added a debit card facility and now are expanding to full credit card capability. What else can you add to a cell phone?"
and some security added to the mix would be nice too!
Of those to whom much is given, much is required.

;) turns out the only math the used was in calculating how tumours grow, and how they prevent immune responses, so they figured out an immune system response they can trigger that will cause the cells that cause tumours to grow to become a 'target' of the patients immune system. no math equasion used to 'cure' it at all, just a little deductive reasoning and science...
the blog entry that they linked to was kinda vauge on details
The Solution: Nuclear Batteries
The market is practically screaming for a battery that doesn't run down in a short period of time. At the very least, nuclear radioisotope technology could be used to create batteries that have longer lives and recharge themselves. If the full potential of this technology were used, then our devices could be powered for YEARS without replacing the battery. Potentially, the battery could even outlast the device!
I realize a lot of people have concerns over the safety of nuclear batteries. But before you run off half-cocked, consider a few points:
1. They use the radiation for power. As a result, the batteries would be designed to capture as much of it as possible. In the case of Alpha and Beta radiation, that can easily reach 100% even if power isn't realized for all of the radiation.
2. You're probably sitting on a highly unstable, very dangerous bomb right now. See that Lithium-Ion battery in your phone? It just happens to be a powerful explosive.
