People naturally sort words and objects into categories, a key process in forming memory. But when it comes to how things are mentally organized, cultures dramatically differ in their strategies.

As I read both Carr and Shirky over the past couple weeks-who both seek parallels between the rise of the internet and digital social media and the invention of the printing press in the 16th century-I couldn't help thinking about medieval manuscripts. Since the early 1990s, both medievalists and electronic media theorists have pointed to the hypertexted quality of medieval illuminated manuscripts in making complementary claims: medievalists to continuing cultural relevancy and electronic media theorists in continuity to literary tradition. The medieval books we admire so much today are distinguished by the remarkable visual images, in the body of a text and in the margins, that scholars have frequently compared to hypertexted images on internet "pages."

IN JUST a few thousand years, we humans have created a remarkable civilisation: cities, transport networks, governments, vast economies full of specialised labour and a host of cultural trappings. It all just about works, but it's hardly a model of rational design - instead, people in each generation have done the best they could with what they inherited from their predecessors. As a result, we've ended up trapped in what, in retrospect, look like mistakes. What sensible engineer, for example, would build a sprawling, low-density megalopolis like Los Angeles on purpose? Suppose we could try again. Imagine that Civilisation 1.0 evaporated tomorrow, leaving us with unlimited manpower, a willing populace and - most important - all the knowledge we've accumulated about what works, what doesn't, and how we might avoid the errors we got locked into last time. If you had the chance to build Civilisation 2.0 from scratch, what would you do differently?

The film tells the story of two ordinary people who are taken into a top-secret military hibernation experiment that goes awry, and awaken 500 years in the future. They discover that the world has degenerated into a dystopia where advertising, commercialism, and cultural anti-intellectualism run rampant and dysgenic pressure has resulted in a uniformly stupid human society devoid of individual responsibility or consequences.

From the 1st through the 6th of February 2011, we were shooting, editing and screening an immediated autodocumentary video at the Transmediale digital art and culture festival in the House of World Cultures in Berlin. Along with events like Ars Electronica and Future Everything, Transmediale is one of the most significant media art events in Europe. We were honored to be included in the Open Zone, a space which will be open to the public, described in the festival programme as "a social experiment with different social territories that are occupied by artists and media activists". We are calling this project The Future of Art. Our goal was a short video which explores questions about the future of art, both in regard to its aesthetics, production, finance, curation, distribution and collection. In addition to conducting interviews at the festival, we were reaching out to several artists in advance of the festival over Skype. Our intention with the Skype interviewees is to extend the discourse beyond the geophysical limits of the festival by including artists who we wish could be here with us in Berlin in February.

Janet K. Swim, professor of psychology, Penn State, and her colleagues report that growing consumption and growing population are two significant contributors to human impact on the environment. Both substantially increase carbon dioxide levels in the atmosphere, the researchers report in a special issue of American Psychologist that focuses on how psychology contributes to understanding and addressing global climate change. "Engaging in one type of environmentally friendly behavior can predispose one to engage in similar behaviors, inhibit other behaviors, or even increase environmentally harmful behaviors," said Swim.

The incidence of type 2 diabetes and hypertension increases with cumulative levels of exposure to nitrogen oxides, according to a new study led by researchers from the Slone Epidemiology Center (SEC) at Boston University. The study, which appears online in the journal Circulation, was led by Patricia Coogan, D.Sc., associate professor of epidemiology at the Boston University School of Public Health and the SEC.

The world in which we live would hardly be recognised by someone who lived and died half a century ago and who may have caught a glimpse of the television generation. The children born in the 90′s have only known a world where the Internet was a natural part of  their day to day lives. We now live in a society that verges on a digital tipping point that wraps and integrates our lives with the Web and it is no longer considered a luxury but a necessity in our modern lifestyle. So what is driving us to this digital dawn that is transporting us from the industrial past of the last 200 years and the TV industrial complex that emerged 50 years ago and embracing us in an information age that challenges our paradigms?

Women have been left defenceless and at the mercy of militia groups in the aftermath of the Iraq war in 2003 according to research from the University of Birmingham.

While many Western retail giants have failed to translate their American success in this booming economy, Apple is winning simply by being Apple.

Research by McGill Sociology Professor Eran Shor, working in collaboration with researchers from Stony Brook University, has revealed that unemployment increases the risk of premature mortality by 63 per cent. Shor reached these conclusions by surveying existing research covering 20 million people in 15 (mainly western) countries, over the last 40 years.

This Friday is not just any old Friday, but it is the kick off of Easter weekend.  In Christianity, of course, this weekend is the celebration of Christ's crucifixion and eventual resurrection and ascension into heaven.  Whether it was planned or a coincidence, This Week's Christiane Amanpour sat down with the Reverend Franklin Graham, son of legendary evangelist Billy Graham.  The topics of social media and the second coming of Christ were among those discussed.

Back in 2009 Mayor Bloomberg prohibited vehicle traffic on Broadway between 42nd Street and 47th Street in Times Square to create a pedestrian plaza (video here). Now, the city's most recent Community Air Survey found that, "After the conversion to a pedestrian plaza, NO pollution levels in Times Square went down by 63 percent while, NO2 levels went down by 41 percent." Unlike N2O, which makes you laugh at Phish shows, NO2, or nitrogen dioxide, destroys your lungs and may cause Sudden Infant Death Syndrome. Nitric oxide (NO) isn't good for you either.

After recently undertaking a journey to walk -- not fly -- across the United States in the "Grounded" storyline and reconnect with the country and everyday Americans, Superman appears to be taking another step that could have major implications for his national identity: in Action Comics #900... ...Superman announces that he is going to give up his U.S. citizenship. Despite very literally being an alien immigrant, Superman has long been seen as a patriotic symbol of "truth, justice, and the American way," from his embrace of traditional American ideals to the iconic red and blue of his costume. What it means to stand for the "American way" is an increasingly complicated thing, however, both in the real world and in superhero comics, whose storylines have increasingly seemed to mirror current events and deal with moral and political complexities rather than simple black and white morality.
