Live Wires Today’s information age rests on a basic understanding of how electrons move. The remarkable success of computers, cell phones, and other devices, such as solar cells, depends on our ability to mediate the flow of electrons through the semiconductors and microchips that control the function of these machines and give them their intelligence. But the importance of electron flow is by no means limited to these man-made systems; electron transfer is also central to energy storage and conversion in living cells. Organisms depend on the flow of electrons for key energy-generating cellular processes. Continuous electron flow is necessary for the formation of the electrochemical gradients that enable the synthesis of adenosine triphosphate (ATP), life’s energy currency. In eukaryotes, including animals, this power generation is the specialty of mitochondria.
Transition to a world without oil: Rob Hopkins on TED Global Issues X marks the spot: This week’s TEDx Talks The paradox of finding peace in a war zone, and a way to make aid more effective — by decentralizing it and thus speeding it up. Each week, TEDx chooses four of our favorite talks, highlighting just a few of the enlightening speakers from the TEDx community and its diverse constellation of ideas worth spreading. […] News X marks the spot: Beatboxing brilliance from TEDxSydney and this week’s favorite TEDx talks The Astounding Design Of Eixample, Barcelona Constructed in the early 20th century, Eixample is a district of the Spanish city of Barcelona known for the urban planning that divided the district into octagonal blocks. Influenced by a range of schools of architecture, Eixample Barcelona was designed in a grid pattern with long streets, wide avenues, and rounded street corners. Despite being in the center of a thriving European metropolis, the district provides improved living conditions for inhabitants including extensive sun light, improved ventilation, and more open green space for public use. And of course, the result from the grid-like structure is astounding from above:
Inside a dead, infected ant Inside a dead, infected ant So, by now you've all seen what a by Ophiocordyceps infected, manipulated and killed ant looks like: Published by Andersen et al. in The American Naturalist, 2009 But what does it look like from the inside? The Book of Symbols: Carl Jung’s Catalog of the Unconscious by Kirstin Butler Why Sarah Palin identifies with the grizzly bear, or what the unconscious knows but doesn’t reveal. A primary method for making sense of the world is by interpreting its symbols. We decode meaning through images and, often without realizing, are swayed by the power of their attendant associations. Boarding a moving train: The way to speed up rail travel? The 'Moving Platforms' concept envisions city-wide tram networks that are integrated with a high-speed rail service. When a tram runs next to a high-speed train, the tram speeds up and train slows down. The moving tram "docks" with the moving train, allowing passengers to cross between tram and train without either vehicle stopping.
Junk DNA — Not So Useless After All Junk. Barren. Non-functioning. Dark matter. Deepermind Table of Contents-George Norwood Home Page March 23,2013 1. Kempf I've been spending time over the last month getting to grips with Petra Kempf's remarkable publication You are the City. Subtitled "Observation, organization, and transformation of urban settings", the main element of this publication are 22 sheets of clear acetate, onto which are printed different conceptual layers and frameworks of a city. It's based on a earlier project called Met(r)onymy 1, from 2001. In 'You are the City', the 22 diagram drawings are split into four operational categories: Cosmological Ground; Leglisative Agencies; Currents, Flows and Forces; Nodes, Loops and Connections. By combining different sheets, and adding layers, a huge range of different compositions can be created - a handmade decon version of SimCity. It invites the user to make new urban connections and realities, as different spatial arrangements and possibilities reveal themselves.
What Does Viper Venom Do To Blood? Snakes routinely make the top 10 list of things people are afraid of, so it might surprise many of you to know that about 85% of snakes worldwide are not venomous. In fact, of the 2,700 known species of snakes, only about 30 of them pose any kind of danger to humans. But, given the amount of damage that a snake bite can inflict, it’s probably not very surprising that a few are giving the others a bad reputation. Take Daboia russelii: an old world viper found throughout India and surrounding countries. Deep Web Intelligence We are finding many different industries are able to capitalize on Data-as-a-Service (DaaS). In this post we’ll uncover how a mining company is using BrightPlanet’s Data-as-a-Service model to monitor the Ebola health outbreak to keep their expatriates informed and out of harm’s way with the use of one dataset. You’ll see what type of data is harvested and how it is enriched to make it usable. Continue reading At BrightPlanet, we receive a number of questions about how BrightPlanet’s technology differs from our biggest competitors.
