The plausible, justifiable motivations of trampled-upon humanfolk to fight back are many—poverty, oppression, disenfranchisement, etc—but the big one is more primal than any of the above. It’s hunger, plain and simple. If there’s a single factor that reliably sparks social unrest, it’s food becoming too scarce or too expensive. So argues a group of complex systems theorists in Cambridge, and it makes sense. In a 2011 paper, researchers at the Complex Systems Institute unveiled a model that accurately explained why the waves of unrest that swept the world in 2008 and 2011 crashed when they did. The MIT Technology Review explains how CSI’s model works: “The evidence comes from two sources. Pretty simple. But how accurate is the model? Today, the food price index is hovering around 213, where it has stayed for months—just beyond the tip of the identified threshold.
But the reality is that such predictions are now all but impossible to make. Using the Archive. Scientists worldwide use our audio and video recordings to better understand and preserve our planet.
Teachers use our sounds, videos, and curricula to illustrate the natural world and create exciting interactive learning opportunities. We help others depict nature accurately and bring the wonders of animal behavior to the widest possible audience. New Guinea's Birds of Paradise Documenting Courtship Behavior For more than a decade, video curator Edwin Scholes has used digital video to document and study the courtship behaviors of New Guinea's birds-of-paradise (family Paradisaeidae). North American Warblers Reproduction, Climate Change, and Songs Mike Webster, director of the Macaulay Library, graduate student Sara Kaiser, and collaborators at the Smithsonian Migratory Bird Center are investigating how birds' behaviors may change in response to climate change.

By Tim RadfordClimate News Network LONDON – A combination of wind and solar power and sophisticated energy storage systems could keep a power grid fully supplied between 90 and 99.9 percent of the time, at costs comparable with today's fossil fuel and nuclear mix, according to a new study from Delaware in the United States.
The key is to get the right combination of electricity sources and storage. - Willett Kempton, University of Delaware Computer simulation measured the performance of inland and offshore wind farms and photovoltaic cells, backed up by battery and fuel cell storage, under the lowest cost conditions, for a 72 gigawatt grid system (one gigawatt will typically provide power for about 750,000 to a million US households)..
