Just a clean up of old articles I accumulated and had no time to post

Society:
-Racing on Carbon Fiber Legs: How Abled Should We Be? I do think that "disable" athlets are heroes.
-Dean Kamen's Full Bionic Luke Arm Video from All Things D. It's about a bionic arm development. I've placed this under society instead of science or medicine simply because of the sociological impact of the development and how the coordinator refers to the lack of courage to invest in bright youth...
-Google ‘no longer willing’ to censor Chinese searches.
-Google, a new approach to china.

Science:
-Artificial leaf could make green hydrogen.
-How to make a liquid invisibility cloak.
-Metal-Air Battery Could Store 11 Times More Energy than Lithium-Ion.

In portuguese:

Humor:
