Wires are dead?

Gizmodo reviews the new line of IKEA's wireless chargers:
IKEA’s wireless charging technology is exactly what it sounds like. It’s a feature being built into a small number of furniture items—namely, lamps and nightstands—but also sold independently as charging pads that you can set on top of a surface or install in any piece of furniture. Once the charging pad is plugged in, you just set your phone on top of a rubber “+” sign. And it charges!

100 years from now you will have your electronic brain implants recharged with a wireless electric pillow while you are sleeping! :)

Speaking of the brain, a group of computer scientists from UCSD and Politechnico di Torino published a paper that describes an implementation of a memory cell-based computing architecture. From the abstract:
Memcomputing is a novel non-Turing paradigm of computation that uses interacting memory cells (memprocessors for short) to store and process information on the same physical platform. It was recently proven mathematically that memcomputing machines have the same computational power of nondeterministic Turing machines. Therefore, they can solve NP-complete problems in polynomial time and, using the appropriate architecture, with resources that only grow polynomially with the input size. The reason for this computational power stems from properties inspired by the brain and shared by any universal memcomputing machine, in particular intrinsic parallelism and information overhead, namely, the capability of compressing information in the collective state of the memprocessor network. We show an experimental demonstration of an actual memcomputing architecture that solves the NP-complete version of the subset sum problem in only one step and is composed of a number of memprocessors that scales linearly with the size of the problem. We have fabricated this architecture using standard microelectronic technology so that it can be easily realized in any laboratory setting.

It's too early to call, but an alternative to the Universal Turing Machine can lead to the creation of novel brain-like applications.
