During the Lakeside Research Days 2012 Vito Trianni form the ISTC-CNR, Rome, Italy and the IRIDIA-ULB, Brussels, Belgium gave a talk about Evolution, Self-Organisation and Swarm Robotics.
If we're going to get science policy right, it's really important for us to study the economic benefit of open access and not accept the arguments of incumbents. Existing media companies claim that they need ever stronger and longer copyright protection and new, draconian laws to protect them, and meanwhile, new free ecosystems, like the Web, have actually led to enormous wealth creation and enormous new opportunities for social value. And yes, they did in fact lead in some cases to the destruction of incumbents, but that's the kind of creative destruction that we should celebrate in the economy. We have to accept that, particularly in the area of science, there's an incredible opportunity for open access to enable new business models.
While the impact of crowding on the diffusive transport of molecules within a cell is widely studied in biology, it has thus far been neglected in traffic systems where bulk behavior is the main concern. Here, we study the effects of crowding due to car density and driving fluctuations on the transport of vehicles. Using a microscopic model for traffic, we found that crowding can push car movement from a superballistic down to a subdiffusive state. The transition is also associated with a change in the shape of the probability distribution of positions from negatively-skewed normal to an exponential distribution. Moreover, crowding broadens the distribution of cars' trap times and cluster sizes. At steady state, the subdiffusive state persists only when there is a large variability in car speeds. We further relate our work to prior findings from random walk models of transport in cellular systems.
The open-source world has learned to deal with a flood of new, oftentimes divergent, ideas using hosting services like GitHub -- so why can’t governments? In this rousing TED talk Clay Shirky shows how democracies can take a lesson from the Internet, to be not just transparent but also to draw on the knowledge of all their citizens.
Clay Shirky argues that the history of the modern world could be rendered as the history of ways of arguing, where changes in media change what sort of arguments are possible -- with deep social and political implications.

What can governments learn from the open-data revolution? In this stirring talk, Beth Noveck, the former deputy CTO at the White House, shares a vision of practical openness -- connecting bureaucracies to citizens, sharing data, creating a truly participatory democracy. Imagine the "writable society" ...
Renowned academic, author, and director of the Mindsight Institute Dan Siegel, visits the RSA to reveal an extremely rare thing - a working definition of the mind.
What is value about? and how do we measure value? Traditionally, the way of measuring value has been not been through measures of value, but actually through measures of appropriation: measures of the amount of money that you can appropriate through that business, not the value that it generates in society. We're starting to see this difference.
TED Talks Ecologist Eric Berlow doesn't feel overwhelmed when faced with complex systems. He knows that more information can lead to a better, simpler solution.
Five great revolutions have shaped political culture over the past 50 years, says theorist Ivan Krastev. He shows how each step forward -- from the cultural revolution of the ‘60s to recent revelations in the field of neuroscience -- has also helped erode trust in the tools of democracy. As he says, "What went right is also what went wrong." Can democracy survive?
In this new RSA Animate, Manuel Lima, senior UX design lead at Microsoft Bing, explores the power of network visualisation to help navigate our complex moder...
Food price spikes in 2007-2008 and 2010-2011 triggered food riots across the world - including the Arab Spring. NECSI was the first to quantify the heightened propensity for violence, unrest and revolution during times of high food prices. NECSI predicted another price bubble and corresponding surge in violence by the end of this year, but the worst U.S. drought in half a century has accelerated this process. Yaneer Bar-Yam will present NECSI's findings linking high food prices and unrest, and outline the significant causes of a decade-long price run-up: excessive financial speculation and the large-scale conversion of corn to ethanol.
The world is changing much more rapidly than most people realize, says business educator Eddie Obeng -- and creative output cannot keep up. In this spirited talk, he highlights three important changes we should understand for better productivity, and calls for a stronger culture of “smart failure."
Shimon Schocken and Noam Nisan developed a curriculum for their students to build a computer, piece by piece. When they put the course online -- giving away the tools, simulators, chip specifications and other building blocks -- they were surprised that thousands jumped at the opportunity to learn, working independently as well as organizing their own classes in the first Massive Open Online Course (MOOC). A call to forget about grades and tap into the self-motivation to learn.
One question that fascinated me in the last two years is, can we ever use data to control systems? Could we go as far as, not only describe and quantify and mathematically formulate and perhaps predict the behavior of a system, but could you use this knowledge to be able to control a complex system, to control a social system, to control an economic system?
Dr Richard Florida, one of the world's leading experts on economic competitiveness, demographic trends and cultural and technological innovation shows how developing the full human and creative capabilities of each individual, combined with institutional supports such as commercial innovation and new industry, will put us back on the path to economic and social prosperity.
In 1999, half of the world had either never used a phone or had to travel more than two hours to reach the nearest one. Years later, mobile devices are being used in extremely innovative ways to connect and empower people around the world.
Because of poor acoustics, students in classrooms miss 50 percent of what their teachers say and patients in hospitals have trouble sleeping because they continually feel stressed. Julian Treasure sounds a call to action for designers to pay attention to the “invisible architecture” of sound.
The main questions I've been asking myself over the last couple years are broadly about how culture drove human evolution. Think back to when humans first got the capacity for cumulative cultural evolution—and by this I mean the ability for ideas to accumulate over generations, to get an increasingly complex tool starting from something simple. One generation adds a few things to it, the next generation adds a few more things, and the next generation, until it's so complex that no one in the first generation could have invented it. This was a really important line in human evolution, and we've begun to pursue this idea called the cultural brain hypothesis—this is the idea that the real driver in the expansion of human brains was this growing cumulative body of cultural information, so that what our brains increasingly got good at was the ability to acquire information, store, process and retransmit this non genetic body of information.
With Big Data we can now begin to actually look at the details of social interaction and how those play out, and are no longer limited to averages like market indices or election results. This is an astounding change. The ability to see the details of the market, of political revolutions, and to be able to predict and control them is definitely a case of Promethean fire --- it could be used for good or for ill, and so Big data brings us to interesting times. We're going to end up reinventing what it means to have a human society.
These three things—a biological hurricane, computational social science, and the rediscovery of experimentation—are going to change the social sciences in the 21st century. With that change will come, in my judgment, a variety of discoveries and opportunities that offer tremendous prospect for improving the human condition. It's one thing to say that the way in which we study our object of inquiry, namely humans, is undergoing profound change, as I think it is. The social sciences are indeed changing. But the next question is: is the object of inquiry also undergoing profound change? It's not just how we study it that's changing, which it is. The question is: is the thing itself, our humanity, also changing?
