households spend more than half of 1 percent of their time online at Wikipedia. The site produces nothing pecuniary owing to its ban on advertising. Yet, it is clearly preferred by many readers, at least judging by the declines in both MSN's Encarta and traditional encyclopedias.

First-authored by Mark D. Huntington, a graduate student in Odom's group, a recent paper in Small ("A Portable, Benchtop Photolithography System Based on a Solid-State Light Source") describes the device that can be constructed from an array of UV light-emitting diodes (LEDs) and powered by AA batteries.

With the world networked on an unprecedented scale, and the global population hitting 7 billion only weeks ago, we are living in a uniquely interconnected era, creating new opportunites and dependencies. It's the result of millenia of exploration, travel, exploitation, and innovation, and the Anthropocene, meaning "the new human-dominated period of the Earth's history," is a term coined in 2000 to describe this epoch. A Cartography of the Anthropocene is an effort by global education organization Globaïa to map this epoch, illustrating the various ways that global humanity connects and is interdependent.

The term "curation" has been floating around lot lately, and Scoop.it is far from the only company in the space. Startups like PearlTrees and Curated.by are just a few of the dozens of such tools out there.

"With seed money from the National Science Foundation (NSF), bioengineers from the University of California, Berkeley, and Stanford University are ramping up efforts to characterize the thousands of control elements critical to the engineering of microbes so that eventually, researchers can mix and match these "DNA parts" in synthetic organisms to produce new drugs, fuels or chemicals."

"In this paper I try to describe analytical patterns developed by the Oekonux Project since over ten years of research on Free Software and commons-based peer production.

Currently food moves from farm to fork linearly across a supply chain designed to maximize investor ROI. This linear design results in a long list of things that are bad for our economy, health, and environment

Globaïa is a global education organization whose mission is to foster a consistent and informed participation of citizens in environmental issues by understanding the multiple dimensions of today's world and its likely future.

"Proposes a framework to explain a collaborative learning process in a community of practice as it interacts with social networking tools. The framework begins with tools and continues through five phases of a learning process and ends with socially-mediated meta-cognition."
