The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions provide the selection pressures necessary for the evolution of advanced cognitive abilities (the ‘social intelligence hypothesis’), and in recent years decision-making in the context of cooperative social interactions has been conjectured to be of particular importance. Here we use an artificial neural network model to show that selection for efficient decision-making in cooperative dilemmas can give rise to selection pressures for greater cognitive abilities, and that intelligent strategies can themselves select for greater intelligence, leading to a Machiavellian arms race.
Hilton Head, S.C., is an island full of sandy beaches, manicured golf courses and lush green trees. But one thing the island community doesn’t have is good cellular coverage. The local government has decided to do something about it, and with the help of mobile crowdsourcing technology, it has begun making its case to wireless operators for better service.
On Tuesday January 24, 2012 President Obama delivered the State of the Union Address. He highlighted the challenges the economy faces and the direction in which we need to take the country. One of the nation’s biggest challenges he highlighted was unemployment. Obviously, jobs are the solution to unemployment. Crowdfund Investing (CFI) also known as equity-based crowdfunding, is a zero-cost government solution to the jobs crisis.
In the 2011 edition of the Corruption Perceptions Index , Kenya is ranked one of the most corrupt countries in the world, coming in at #154 out of 182 countries on a list that ranks countries from least corrupt to most corrupt. In fact, bribery is such a common practice in Kenya that it's estimated that Kenyans pay, on average, 16 bribes per month. But now Kenyans are fighting back against their country's stigma, and in order to do so they’re using the power of the Internet and of crowdsourcing. Hatari , which means "danger" in Swahili, is the name of the new platform that Kenyans are using to report incidents of crime and corruption in the city of Nairobi.
An enzyme designed by players of the protein-folding game Foldit was better than anything scientists could come up with. Obsessive gamers’ hours at the computer have now topped scientists’ efforts to improve a model enzyme, in what researchers say is the first crowdsourced redesign of a protein. The online game Foldit, developed by teams led by Zoran Popovic, director of the Center for Game Science, and biochemist David Baker, both at the University of Washington in Seattle, allows players to fiddle at folding proteins on their home computers in search of the best-scoring (lowest-energy) configurations. The researchers have previously reported successes by Foldit players in folding proteins 1 , but the latest work moves into the realm of protein design, a more open-ended problem.
Foldit is a revolutionary new computer game enabling you to contribute to important scientific research. This page describes the science behind Foldit and how your playing can help. What is a protein? Proteins are the workhorses in every cell of every living thing. Your body is made up of trillions of cells, of all different kinds: muscle cells, brain cells, blood cells, and more.
Welcome. We live in an urban age. And while technology will surely make cities smarter and more connected, we know that what makes a city great is how we experience it as people. The good news is that cities are becoming more open, more liveable, and more aware of their footprint on the planet.

Bey2ollak is one of two Egyptian start-ups which are US bound, following their participation in the NexGen IT Entrepreneurs Boot Camp last month. Hearing the news that American and Danish entrepreneurs were flying in to Cairo, to host a seminar especially for Egypt’s up-and-coming start-ups, one of Bey2ollak’s five co-founders, Mohamed Rafea snagged a spot at the table. Bey2ollak is the brainchild of five cousins. Aly Rafea, Mohamed Rafea and Gamal Sadek, all computer science graduates, were responsible for development. Mostafa Beltagy, a business administration graduate, took on marketing, while Yehia Ismail, an architect by profession, was responsible for the design and UI. Bey2ollak is a cross-platform mobile app allowing users to share real-time information about Cairo and Alexandria traffic.
"Abstract This qualitative phenomenological study involving in-depth interviews with seven educators in K-12 and higher education examines the role that the microblogging service Twitter plays in the formation and development of Personal Learning Networks (PLN) among educators. A double hermeneutic data analysis shows that Twitter plays a role in the formation and development of PLNs by allowing educators to; engage in consistent and sustained dialogue with their PLN, access the collective knowledge of their PLN, amplify and promote more complex thoughts and ideas to a large audience, and expand their PLN using features unique to Twitter. This research also examines the nature of a PLN and shows that participants believe their PLN extends beyond their Twitter network to encompass both face-to-face and other ICT mediated relationships.

"Today, TED announced the winner of the 2012 TED Prize: the City 2.0. Breaking from their tradition of recognizing an individual global innovator, TED is embracing the concept of crowd-sourcing urbanism (an idea we obviously support at Open Source Cities). The organizers published this call-to-arms in seeking ideas on the City 2.0:
