- Printable, electrically conductive gel with unprecedented electrical performance synthesized – The gel's conductance is "among the best you can get through this kind of process," said Cui. Its capacity to hold charge is very high, and its response to applied charge is unusually fast.
The substance's similarity to biological tissues, its large surface area and its electrical capabilities make it well suited for allowing biological systems to communicate with technological hardware.

- Freedom and Frugality | Laissez-Faire Bookstore – A few years ago, my view of frugality changed due to an obvious realization that I had never fully grasped before. Material goods cost money; money is acquired in exchange for my time; my time is literally my life. If X costs $100 and I make $25 an hour, then X costs me four hours of life. Or rather, it costs four hours plus whatever time is consumed by the transaction costs of making money, such as the time and expense of a commute.
This was a paradigm shift for me. I ceased viewing possessions in terms of money and saw them in terms of time. And my time is a scarce good. The hours available can sometimes feel boundless, and it is easy to fall into the trap of valuing each unit as if it were part of an infinite supply. Of course, it is not. There are only so many hours left for me to live.
