Panarchy Panarchy What is Panarchy? Panarchy is a conceptual framework to account for the dual, and seemingly contradictory, characteristics of all complex systems – stability and change.

4 Rare Earth Elements That Will Only Get More Important Sir William Crookes, a 19th century British chemist, once wrote that, "rare earth elements perplex us in our researches, baffle us in our speculations and haunt us in our very dreams." These weren't easy elements to isolate or to understand, and so there was a very long lag time between the discovery of the rare earths, and the discovery of practical uses for them. It didn't help that individual rare earth elements don't occur by their lonesome—they travel in packs. Lost at sea. Military loses contact with hypersonic test plane By Adam Levine Military researchers conducting the flight of the fastest unmanned aircraft ever launched said Thursday an "anomaly" caused a lost contact with the vehicle nine minutes into its flight. The plane is believed to have crashed in the Pacific at some point along the planned flight path, according to a statement from the Defense Advanced Research Project Agency (DARPA), which conducted the test. The Falcon Hypersonic Test Vehicle (HTV-2) had successfully separated from the launch vehicle and was performing "glide phase" maneuvers meant to test its aerodynamics when contact was lost, according to an 11 a.m.
When will computer hardware match the human brain? by Hans Moravec Journal of Evolution and Technology. 1998. Vol. 1 When will computer hardware match the human brain? (Received Dec. 1997) Hans Moravec ABSTRACT This paper describes how the performance of AI machines tends to improve at the same pace that AI researchers get access to faster hardware. Meghalaya villagers create 'living' bridges by training roots across a river By Daily Mail Reporter Updated: 15:35 GMT, 10 September 2011 Deep in the rainforests of the Indian state of Meghalaya, bridges are not built, they’re grown. Ancient vines and roots of trees stretch horizontally across rivers and streams, creating a solid latticework structure strong enough to be used as a bridge.
Secrets of the first practical artificial leaf A detailed description of development of the first practical artificial leaf -- a milestone in the drive for sustainable energy that mimics the process, photosynthesis, that green plants use to convert water and sunlight into energy -- appears in the ACS journal Accounts of Chemical Research. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from inexpensive materials and employs low-cost engineering and manufacturing processes. Daniel G. Nocera points out that the artificial leaf responds to the vision of a famous Italian chemist who, in 1912, predicted that scientists one day would uncover the "guarded secret of plants."
The first flexible, fiber-optic solar cell that can be woven into clothes An international team of engineers, physicists, and chemists have created the first fiber-optic solar cell. These fibers are thinner than human hair, flexible, and yet they produce electricity, just like a normal solar cell. The US military is already interested in weaving these threads into clothing, to provide a wearable power source for soldiers. In essence, the research team started with optical fibers made from glass — and then, using high-pressure chemical vapor deposition, injected n-, i-, and p-type silicon into the fiber, turning it into a solar cell. Here Are All 56 Finalists In Our 2012 Innovation By Design Awards Design isn’t the gloss applied at the end of the innovation process. Design is the innovation process itself. It begins with a keen insight into how people live and what they need; ideally, it ends with a product or service that’s so intuitive that it seems inevitable. It’s in that spirit that we present our first Innovation By Design Awards. The 56 finalists you see here were culled from the over 1,700 entries we received.
TreeHugger iFixit/CC BY-ND 3.0People are talking a lot about cell phone unlocking in the news this week. Until recently, unlocking mostly flew under the radar—a common technique used by consumers who need to use their phones with more than one carrier. But late last year the Librarian of Congress banned the practice, catapulting cell phone unlocking into the national spotlight. Unlocking is a software tweak that disables a device’s SIM lock.

Energy company to test floating solar islands Swiss energy company Viteos has announced that it is to build three floating solar arrays on Lake Neuchâtel. Viteos will work with tech company and "energy enabler" Nolaris to build the 25-m (82-ft) diameter islands, each with 100 photovoltaic panels. View all Japanese breakthrough will make wind power cheaper than nuclear NOTE: Some major wind projects like the proposed TWE Carbon Valley project in Wyoming are already pricing in significantly lower than coal power -- $80 per MWh for wind versus $90 per MWh for coal -- and that is without government subsidies using today's wind turbine technology. The International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possesses 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy. This makes the U.S. something of a Saudi Arabia for wind energy, ranked third in the world for total wind energy potential. The United States uses about 26.6 billion MWh's, so at the above rate we could satisfy a full one-third of our total annual energy needs. Now what if a breakthrough came along that potentially tripled the energy output of those turbines?
